Foolproof, by Sander van der Linden: a recommendation, review, and analogy with psychotherapy

I strongly recommend a new book by Cambridge psychologist Sander van der Linden, entitled Foolproof: why misinformation infects our minds and how to build immunity.

I have followed van der Linden's research for several years, alongside other experts who are studying the psychology of persuasion, misinformation, and propaganda.    This area has been an interest of mine for many years, after discovering psychologists such as Cialdini and Kahneman.  

This is a subject that everyone needs to learn about!  Persuasive techniques (for good and for bad) have always been with us through history; the power and influence of these techniques will only continue to escalate, thanks to the internet era, and now the era of artificial intelligence (AI).  

I have discussed these issues in other posts, such as:


and 


and 

Garth Kroeker: "GroupThink" (October 6, 2016) 

Van der Linden reviews the history and scope of misinformation.  Among the many current examples are conspiracy theorists impacting public opinion and policy, political influencers attempting to sway elections, propagandists from other countries defending violent or oppressive policies or sowing discord among their opponents, and of course the anti-vaccine community.  

There are a couple of acronyms he introduces: the word CONSPIRE can help us to recognize some of the common features of conspiracy theories:  

C = contradictory.  Most conspiracy theories feature contradictions.  For example, there could be a belief that some awful event is a hoax, but then also a belief that the awful event is real but was caused by evil conspirators.  

O = over-riding suspicion.    A sense of general distrust that goes beyond the topic of the conspiracy theory, particularly a distrust of official or mainstream explanations.  

N = nefarious plot.  A belief that there is a shadowy group of evildoers, such as government officials, corporations, or (at worst) a particular racial or ethnic group, who behind the scenes have caused some bad thing, perhaps with a motive to advance themselves.  

S = "something's wrong."  The belief that regardless of any acknowledged or corrected fact about an event, there's something going on that isn't right.  

P = persecuted individual.  The belief that someone is being deliberately harmed (most commonly, the believers in the conspiracy theory).  

I = immune to evidence.  Presentations of evidence often have little or no effect to change the opinion of people having conspiracy theory beliefs, in fact evidence could even "backfire" and cause the conspiracy theorist to become even more entrenched, or to believe that you or your sources of evidence are all biased or part of the conspiracy.   Such immunity to evidence is common among people who have limited expertise or knowledge about science, but could also be present in some highly educated people.  A conspiracy theorist who does have more scholarly expertise may understandably deploy statistical or psychological terminology to defend their beliefs; for example, by accusing other scholars of having psychological biases (such as confirmation bias).

Re = reinterpreting randomness.  This is creating a false causal story about random, unrelated events.   Humans in general are prone to doing this.   

It's interesting as a psychiatrist to reflect on the "CONSPIRE" factors above.  They are very often present in frank psychotic states, or in milder variants such as paranoid personality.  The tendency to have paranoid thoughts exists as a trait on a continuum in the population.  This trait has various environmental causes, but also has a high heritability.   It is a typical psychotic symptom to believe that there is a special, often ominous explanation behind pseudorandom events.    

Of course, sometimes there are explanations for events which differ from the mainstream understanding.  Through history there have always been maverick scientists,  who demonstrated something new and important, despite the objections or condemnation of their peers.  One example that has always bothered me was Alfred Wegener, who in 1912 was the first to propose the theory of continental drift; he was ridiculed and dismissed by his peers, who couldn't believe that entire continents could move across the face of the earth; Wegener tragically died before his theory was proved correct.   We have to be open to consider alternative theories.  However, maverick scientists, unlike conspiracy theorists, have clear evidence to support their claims; their reasoning does not contain contradictions; they are not immune to evidence, do not reinterpret randomness, and do not have ominous, over-riding suspicious beliefs about persecution.  

Van der Linden's next acronym is "DEPICT", to help remember features of manipulative communication:
  
D - discrediting.  The manipulative communicator will portray experts who disagree with them (such as scientific leaders, or even entire communities such as leading scientific journals), as biased, poorly qualified, incompetent, or having some nefarious agenda.  It is frustrating to have a scientific debate with someone who is engaging in such discrediting, since any sound evidence you raise with them will be dismissed as invalid.  

E - emotional.  Using strong emotional language to induce fear, anger, or disgust as a persuasive tool.  

P - polarization.  Framing issues, and people who have positions on these issues, in a "black or white" fashion, rather than as shades of grey.  This leads to a false sense of dichotomy, and encourages the formation of teams of opponents holding increasingly extreme positions, and increasing disrespect for those who disagree. 

I - impersonation.  Using fake experts to bolster a claim.   A variant of this is using an actual expert, but whose expertise has nothing to do with the issue at hand.  

C - conspiracy theories.  Encouraging conspiracy theory beliefs. 

T - trolling.  Attacking, insulting, or threatening opponents, usually in an online environment, such as on social media.  Such harassment has at times been so intense that scientists or policy experts (including in public health) have been afraid to speak out, fearing for their safety.  

Van der Linden's work focuses on how we can best deal with misinformation.  He concludes with an analogy:  misinformation must be dealt with by "immunizing" ourselves against it.  

In order to build immunity against an infectious disease, it is necessary to be exposed to a weakened version of the pathogen, in order to train the immune system, such that future doses of pathogens would be dealt with quickly.  

Infectious diseases are much easier to manage, with much less risk of harm or spread, by building immunity, rather than by only relying on treatment after infection.   

Similarly, it is much harder to "treat" misinformation after the fact.  Tactics to "treat" misinformation would be debate, education, and careful review of evidence.  But many people who have fallen into a misinformation "rabbit hole" are difficult to reach or persuade using reasoned debate.  Such debate may even cause the misinformed person to become even more angry or stubbornly adherent to their ideas.    

It is better to prevent people from falling into the rabbit hole in the first place--not by eliminating rabbit holes (which is impossible) but by teaching people how to identify and manage rabbit holes if they encounter them.  

The idea of "vaccination" is presented as an analogy throughout the book.  But beliefs and persuasion are not exactly like the body's immune system.  It's a very good analogy, but not perfect.  Much of the phenomenon van der Linden is talking about is explainable through learning theory:   we learn much better if we actually practice "hands on" with things, rather than just passively absorbing theory.  If you want to learn mathematics, you actually have to work through a lot of problems, not just read about how to do them.  If you want to learn how to ride a bike or drive a car, you have to practice cycling and driving, not just read about those things in a book!  As part of the practice, it is best to face challenging situations, and learn through experience how to overcome them.  

Similarly, to deal with emergencies, it is imperative to do behavioural practice many times as a preparation.  We have to do fire drills to prepare for a potential fire.  Pilots need to practice many times in a simulator how to manage engine failure.  If you only read about something, or learn about something, without practicing, you can't possibly become proficient, especially under pressure.  

To deal with misinformation, we have to practice, hands-on, dealing with misinformation, at first with "easy" examples, then more and more difficult ones.  

Applying these ideas to psychotherapy: CBT (cognitive-behavioural therapy) is very important and useful, but at worst it can be too passive.  Many people engaging in CBT do a lot of passive learning, they do written exercises in a workbook, but do not really practice deliberate exposure to uncomfortable stimuli.  The "vaccine" analogy could be useful to incorporate into CBT for treating depression or anxiety.   This is something that I have advocated for many years, mainly an emphasis on the "B" part of CBT.  To deal with panic attacks, it is most helpful to actually practice having panic attacks, in safe, controlled conditions!   To deal with depressive thoughts, it could be a useful exercise to invent simulated depressive thoughts, at first mild ones, then more challenging ones, to understand the mechanism by which they are created, and to practice facing them without being negatively affected.   This exposure therapy is like van der Linden's "vaccine."  But most therapists don't emphasize this enough, they only try to teach people to relax or cope with symptoms after they have occurred.  One of the purposes of talking about past emotional trauma is to recreate the painful events in the mind, but in a limited, controlled, "virtual" form, within the safe context of a therapy office.  In this way talking therapy has a vaccine-like effect.  

Linden's book is a must-read, not only for those interested in propaganda or misinformation, but also for anyone wanting a better understanding of the mind itself, with ideas that touch upon managing almost any life adversity, including mental illnesses.

Garden metaphor

This is an update of a post I originally wrote in 2008.

The brain, or the mind, or your life, is like a garden.

It has grown for many years, and there are aspects to the structure that are, or become, permanent (e.g. the size and shape of the garden).

Some structures in the garden may be dominant (e.g. a tree that monopolizes sunlight, water, space, or nutrients).

Some structures may be permanent (a tree), others transient (some small flowering plants).

There may be weeds in the garden. Or maybe they are only "weeds" because someone has said they are weeds, just because they are considered weeds by other gardeners. Maybe the beauty and importance of many so-called weeds are overlooked.

There may be parts of the garden that are profoundly important, extremely beautiful, and extremely complex, yet are not noticed because we haven't looked in the right way (e.g. tiny flowers; micro-organisms; ladybugs; close-up views of the structure of the leaves, etc.).

Old or dying plants may be integral parts of the normal life cycle of the garden, as things of beauty in themselves, and as components that help new life to grow.

There may be diseases in the garden that do harm in different ways (above the soil or below).

There may have been terrible events long ago that have done severe harm (a fire; an oil spill; a vandal; a careless former gardener; bad droughts or storms; a lighting strike).

The garden requires a healthy environment to grow, both above and below the soil. Sunlight, water, nutrients, soil conditioning.

The structure of the garden can get tangled up and confused if it isn't tended to regularly. It can get messy. The tangles may prevent certain beautiful plants from being cared for or thriving. The tangles can occur above the ground, or down underneath at the root level.

The structure of the garden can be stunted if it is tended excessively -- the overzealous pruner who cuts too many branches away, instead of letting the natural shapes and stems grow spontaneously.

In healing a troubled garden, sometimes simple, broad measures can make a huge difference (e.g. adding nutrients to the soil; introducing a new type of soil; keeping up this supplementation for months or years).

Other times, or perhaps in conjunction, work may need to be done to prune or guide the garden differently, above and below the ground. Some of this work can happen in a day, other aspects of this work could take years.

Maybe a major change is needed. A huge plant that is taking up all the space, water, and light, may need to be removed, so that other plants have a chance to grow.

Sometimes things that supposedly help need to be cut back -- maybe the garden is being over-watered, or is getting too much sun. Many of the plants may require moderation in order to thrive. There can be too much of a good thing.

New species may need to be introduced, to balance the health and esthetics of the garden. Synergistic benefits can happen with the right combination of species (two different species may help each other grow if they are adjacent to one another).

The effects of past trauma in the garden may gradually heal with care and attention. Some of the scars of the trauma may remain forever. Even if these scars remain, the other plants of the garden, and the gardener, can support the injured plant, help it be a vital, important, and beautiful part of the garden community.

While caring for the garden may be hard work, the process is intrinsically a joy. The results of the gardening are part of the health, but so is the process of the gardening activity itself.

In caring for your mind, you are taking on a role of gardener.  It is possible to "tend the soil" in many ways.  Part of this requires physical labour to improve the texture and drainage.  Sometimes the soil may be depleted or damaged in some way, and a fertilizer may be needed, at least for a little while.  This could be similar to using medication.  But also there are many other ways to care for the "soil," such as by having a healthy diet.  Psychotherapy is analogous to hiring a gardener to help and advise you, and maybe to work with you, kneeling in the soil, or pruning the branches.  Sometimes major structural changes may be needed, to plant the garden in a completely different way...this is akin to making a substantial change in the organization of your life, your goals, and your relationships.  And the best gardens are attuned to the larger ecosystem around it, including other gardens in the neighbourhood.  This is analogous to the need to healthily engage in your community, and in relationships with others.    Part of the life of a garden, and of a gardener, also requires simply sitting down and enjoying its beauty.

There may be hard work to do, but there must also be a lot of time spent simply savouring your efforts, and enjoying the view.  I hope that a good therapist might do this with you as well.  Make sure there is a bench in your garden, in a shady spot, in order to rest and enjoy.  In your life, there may be a lot of work to do, but make sure to spend time, every day, sitting down and enjoying what you have been working on.

Feeling Trapped in a Life You Don't Want: Hopelessness & Chronic Depression

I originally published this post in March, 2009.  I was just looking at it again today, while browsing through my blog...I thought I would re-publish this, and maybe work on adding to it.   I have been reviewing treatment guidelines for mental illness, and have been asked to help prepare some official guidelines for my workplace...while I find this task, of preparing "guidelines,"  meaningful or useful in some ways, with some worthwhile observations and tips to be discovered in the existing research, I finally find the task a great source of weariness and frustration.  This particular post really represents something that is much, much closer to the "core" of who I am, or who I want to be, as a psychiatrist.  And it reflects more deeply--than any "guideline" could-- my beliefs about caring for people who are suffering.   


This post is in response to a comment on my previous post "What to expect from an antidepressant".

What is the purpose of a life?

What needs to be present in a life to make it worthwhile?

If a life is like a work of art, a giant canvas that you have been working on for decades--what if you feel that the canvas has already been wrecked? The damage may have been caused by "bad genes" (e.g. an inherited tendency to be depressed, etc.), which in the canvas metaphor might mean the canvas itself is fragile, thin, easily damaged, doesn't hold pigment very well, etc.

Or the damage may have been caused by "bad environment" (e.g. a traumatic childhood, lack of support, lack of opportunity, natural disasters, war, poverty, etc.), which in the canvas metaphor might mean the canvas itself has been damaged by others, or by environmental adversity, causing it to be very difficult or painful to work with in the present.

Or the damage may have been caused by your own past efforts (e.g. a history of spending years trying to develop oneself-- in school, in relationships, in work, etc.--but where these efforts have ended in failure, pain, breakups, sorrow, regret, guilt, or a sense of having burned your bridges--and where the past failures obstruct future opportunities, e.g. via a poor academic transcript, work record, etc.). In the canvas metaphor this might mean there is a lot of paint on the canvas, but none of it is what you want, none of it is where you wanted it to be, none of it you actually like, it all looks like a collection of mistakes. If it was a literal canvas, you might feel like the best action would be to just throw the painting away, and either start fresh, or give up painting altogether. You might feel like you never wanted to paint in the first place, that the task was forced upon you by the fact of your birth, and by the social expectation that you are supposed to live out your life.

For many people who struggle with chronic depression, I think there is some combination of all these three possibilities: genes, external environment, and personal efforts which haven't worked out, all contributing to a state of hopelessness, tiredness, exhaustion. It can feel like a daily struggle just to make it through the day, a yearning for time to pass just for things to be over. Life can feel like a trap, a life sentence to a prison term, a forced existence that you never really wanted, or have long since stopped wanting.

The idea of a medication somehow "treating" this problem can seem absurd. Or the idea of so-called "cognitive therapy" changing this problem can seem insulting. It is like observing a painting you don't like in an art gallery, and then being told that you have to do some exercises to change your thinking, so that you will start to like it, then have it up on your living room wall for the next 60 years. In some ways this dynamic reminds me of salesmanship, in which case it can feel like the therapist, or even the whole external world, is trying to "sell you" the idea that your life is supposed to be worthwhile, when all you see is something you hate and want to get rid of.

I don't have easy answers to this problem.

But here are some of my beliefs about approaching it:


There are people who will care about you, and who will sit with you through your suffering. A role of a therapist in this type of situation, I think, is to sit quietly, to be gently and consistently present.

The world is full of possibility. No matter how bad conditions have been--internally or externally, past or present--growth and change are possible. The brain is a dynamic structure. It is as powerful and consistently active when alive as is the heart. But the brain reinforces its own pathways. If these pathways give rise to feelings of despair, hopelessness, and futility, then every moment of life can become experiences of despair, hopelessness, and futility. If these pathways of thought, emotion, and felt experience, have been trodden for decades, it can be hard to forge new pathways within the mind.

Immense, profound life change is possible, regardless of how severe problems have been, how long they have been present, or how much damage the problems have caused.

Such changes may require an enormous amount of energy and time, and may require a lot of external support.

There are many individual life stories of profound life change, stories of journeys through chronic hopelessness towards meaning, energy, and joy. Historically, some of these stories are of mythical proportion, and are present in literature and the other creative arts. Many religious stories contain themes of this sort.

Contemporary examples include stories of individuals overcoming lifelong addictions which had devastated their previous life histories (here I am not saying chronic depression is an addiction, but that addictions and depression can both be characterized by feeling very stuck in something bleak and hopeless). The lore in addiction treatment has wisdom to share about making radical life change--in "12 step" models, for example, individuals are called upon to admit "powerlessness" over their problem, and to make a set of statements of faith about a "Power greater than ourselves", etc. While I am wary of the potential for dogmatic religiosity in such statements, I also see that if dogma can be set aside, the "12 steps" can be seen as a sort of "leap of faith", a new contract with life, to live--and work-- with the help of a supportive community. It admits, powerfully, that one must reach out to connect with the possibility of change, it is almost impossible to do alone (the "higher power" idea can simply be an admission that one needs external help).

Psychiatric medications in chronic depression usually do not lead to "profound life change" (sometimes they do, but really this is in a small minority of cases). However, often they help a small to moderate amount. Either to relieve some suffering or pain, or to potentiate energy that might then help to effect a new course in living. I do not feel that any effective treatment leads a person to become resigned to an unpleasant status quo, and then to learn how to "accept a bad life". I feel that effective treatments allow unpleasant circumstances to feel more bearable, then to facilitate the hope and actions that are necessary to improve the unpleasant circumstances.

Cognitive therapy can help. The goal, however, in cognitive therapy, cannot be simple "salesmanship". I think the goal has to be building a satisfying life, where there are healthy, stable relationships: meaningful work, meaningful love relationships, and meaningful activities that bring joy or happiness.

With any type of process that causes deep changes in the brain, the pathway may require you to go right back to the simplest foundations.

I'm reading Norman Doidge's book about "neuroplasticity" right now (The Brain that Changes Itself), which incidentally I recommend highly. The evidence he presents is quite convincing, to some degree surprising, but on another level intuitively very obvious--the brain can change itself, sometimes very radically.

But if new paths are to be formed in one's "mental forest" one may need to start with tasks that seem extremely simple, even infantile, perhaps even "insulting" in their simplicity. Cognitive therapy can seem extremely trite, or even a ridiculous exercise in mental manipulation--an exercise to comform oneself to how society as a whole expects you to think or feel, trying to convince you to think good thoughts about a bad situation.

The thing is, though, these seemingly ridiculous tasks (such as cognitive therapy, etc.) can start new paths forming. In conjunction with this, new connections can begin with the external world, in the form of new friendships, new involvements in creative work, new involvements in education, etc.

There may well be burned bridges, but there is a vast energy available to build new bridges, if you so wish. And your past experiences may eventually become more useful to you than they are right now.

Depression can be extremely tenacious. It is so extremely tenacious that in some cases it is almost like a character that wants to perpetuate itself. The depression itself, so to speak, sets up arguments in one's mind about why this or that action (e.g. medication, therapy, life change of other sorts) cannot or should not happen. In the forest path metaphor, it is like the depression not only has become an extremely well-trodden pathway in a dense forest, but it has also put high fences around the pathway, and a deep moat full of crocodiles on the other side of the fence too.

Once again, I emphasize that I have no easy answers. As I look at the above post, I see that it is rambling. Parts of it probably sound preachy or trite. Probably annoying to look at if you are feeling trapped in a depressive state. I think I come off sounding like a salesman myself, trying to convince you to buy that painting you don't really like.

My intention, though, is to convey my belief that change is possible. There is proof that change is possible. I see this proof in my own clinical experience, as well as in the stories of others. Deep change in a chronically unhappy life is possible, but may require a great deal of external help, and may require a type of commitment to change that is extremely difficult or exhausting to initiate. And your depression won't want you to make any such commitment.

The Better Angels of Our Nature: Why Violence Has Declined, by Steven Pinker: A Book Review, Part 3

So, in conclusion, Pinker's book is very important and can be broadly applied not only to understanding and working towards continued reductions in violence, but these ideas can be useful in developing healthier psychological strategies in daily life.

These principles include:

1) continued education, to bolster reason, cross-cultural understanding, communication skills, empathy, historical knowledge, and even economics and statistics (these latter subjects can help combat cognitive biases which impede clear understanding of information pertaining to daily living)

2) foster trade instead of fostering war.  In some recent news examples, this may not be reasonable (e.g. with some extremely violent groups), but at the very least, fostering trade with adjacent communities would be useful to form alliances. 

3) exercise and strive for freedom of speech

4) expand our circles of empathy, to include those in other groups, cultures, and situations.  Ultimately, a global issue is to include the environment itself in our circle of empathy.  In depressive states, one may be directing aggressive thoughts or actions towards oneself.  So the circle of empathy should deliberately also focus on including oneself.

5) be aware of cognitive biases, such as overconfidence in the setting of conflict, underestimation of the risks of conflict, the tendency to deliver vengeful retaliations that would be considered excessive by a neutral observer, and to overestimate the malevolence of an opponent's motives.    This could be applied to an analysis about one's own depressive thoughts about oneself.

6) avail oneself of mediators or peacekeepers (this can be a role of a therapist).

7) move away from authoritarian or tribalist practices or beliefs, and instead focus on inclusiveness, individual rights, and fairness.  For those involved in religion, work toward a more inclusive, peacemaking, ecumenical, humble theology, with room to include modern scientific findings pertinent to morality, fairness, cultural understanding, and justice. 

8) strive for dignity rather than honour

9) work on ways to improve self-control.  This does not mean a renunciation of Dionysian enjoyments, but rather it means never allowing one's impulses or habits or enjoyments to cause harm or to rule one's life.




The Better Angels of Our Nature: Why Violence Has Declined, by Steven Pinker: A Book Review, Part 2

The first section of Pinker's book is an exhaustive review of violence rates throughout history.  This even includes looking beyond our own species, to other great apes, to understand aggression in our evolutionary lineage.  He also reviews cultural attitudes towards violence throughout the ages, as manifest in literature and the arts, and also in accounts of daily social and entertainment practices.  It is very disconcerting to learn about the extent to which horrifying acts of cruelty were commonly accepted, or even considered amusements (the events in the Roman Colosseum comprise just one of many, many examples)

Clearly, rates of violence were much, much higher in all previous periods of history.  Today the risk of suffering a violent non-suicidal death (from war or other crimes) is in the order of 1% or less (this is the total risk over an entire lifespan).    In most prosperous areas of the world it is much less than 1%.  Of the 245 000 deaths in Canada in 2012, 543 were due to homicide (0.2 % of the total).link   link2

But in all previous eras of human and pre-human history, these risks were orders of magnitude higher,  according to a variety of streams of evidence which Pinker amasses.  Instead of 0.2%, the rates were 10% or more.    If anything, much of this data may actually underestimate these past rates, since violence was so much a norm in previous periods of history that many violent deaths or even massacres were barely mentioned in historical texts.  Risks of non-homicidal violence were much higher still, such that most everyone in the population would have been traumatized in some way, or would have had a close friend or family member who was severely traumatized. 

Pinker outlines various of the forces which have driven violent behaviour over the ages; here are some of them:

1) predation
2) dominance
3) revenge
4) communalism/tribalism/nationalism
5) sadism
6) isolation
7) authoritarianism
8) ideology
9) lack of intelligence

1)
Predation is described as a simple goal-oriented motive, such as robbery or looting.  Yet this strategy is "zero sum" or "negative sum" in that there is no net gain during a robbery, only a transfer of property, and most likely a destruction of the means to efficiently produce more property (e.g. jewelry may be stolen in an attack, but the infrastructure or morale needed to produce more or better jewelry gets damaged in the process).

With societal evolution, free trade becomes a non-violent alternative to predation, which allows the process to be "positive sum."   In this case, goods could be traded for jewelry, leading to a prospering group of jewelers who can then produce more or better jewelry in the future.  Both parties gain.   In order for free trade to occur, and the ensuing reduction in predatory violence, there must be improved communication, a fairly governed commercial system, and penalties for predation which are agreed upon by both parties.

In a psychotherapeutic milieu, this principle could lead to the idea of improving communication and stable transactional rules between potentially conflicted individuals.  In general, the idea of trading with your enemy instead of fighting your enemy may not naturally occur to people.

Pinker does not adequately discuss some of the problems with trading relationships, and of free-market economics in general.  Such relationships can be imbalanced, exploitative on some level (either directly towards the individuals or nations involved, or towards the environment), or favouring a relatively small elite while having little benefit for the majority.  I think there needs to be more emphasis on "fair" trade, including a strong focus on environmental issues.  This is consistent with Pinker's observations about the need to expand a "circle of empathy."  This circle should expand to include not just trading partners, but the larger communities affected by trade, and the benefits or consequences to the natural environment.  Trade may often benefit the environment, through a simple economic efficiency argument:  the lowest-cost economic solution to a problem is favoured by free trade, which in turn can maximize the available eonomic resources to protect the environment.  But in order for this efficiency to be protective, there needs to be structured safeguards in place to prevent social or environmental exploitation. Another big issue I have found with conventional economic theory is that costs are underestimated (such as long-term environmental damage), and the cross-sectional cost appears to be very low; often those involved are not held responsible for the ultimate long-term costs.  In any case, this inaccuracy in measuring costs distorts the system, and causes it to be short-sighted.  

2)
Dominance contests can be seen in many species, often as part of a competition for mates.  Most often, of course, these are behaviours seen in males.  In humans, this can give rises to meaningless displays of strength or machismo, with an associated culture of "honour" in which small perceived slights can result in excessive aggressive reactions. Associated psychological phenomena include overconfidence, underestimation of the losses associated with the conflict, and of course lack of empathy for the opponent. In celebrating a culture of "glory and honour" there can be an utter disregard for the individuals and families affected by the ensuing violent losses.

If this type of behaviour is selected for in the population, it gives rise to large, aggressive, arrogant, reckless males who are easily provoked.  In other species it can give rise to males having harems with multiple mates, while driving away or killing other male challengers  (we see literal examples of this in human groups throughout history). 

In humans, this type of dynamic can occur in "honour-based" cultures; previous periods of history often featured distinguished gentlemen absurdly fighting to the death in duels, often over trivial conflicts.  But entire nations can behave in this fashion as well.

Improvement in this type of problem comes with greater education, strong emphasis on women's rights and gender equality, and selection pressure:  reckless, aggressive males with poor impulse control are much less likely to be found attractive as mates in the modern era!   Instead, most elements of modern culture favour self-control and a culture of "dignity."  It is no longer cool or attractive to be a bully or a hothead. 

3)
Revenge is an understandable reflexive process, and it is pointed out that some degree of revenge can be a deterrent to subsequent violence (to show no revenge can invite subsequent exploitation).  The problem with revenge, as Pinker shows, is twofold:  first, wronged individuals or states tend to want to deliver more punitive harm than a neutral mediator would prescribe.  The individuals doing the wrong likewise tend to underestimate their culpability or guilt (e.g. a great many convicted felons may have a smaller estimation of the magnitude of their guilt or responsibility for harm than a neutral observer or their victims would conclude).  This leads to a cycle of revenge, in which each group retaliates vindictively against each other, with force that is often out of proportion to the offense, and each wrongdoer underestimates their culpability.   The retaliation is itself therefore felt as an assault by the recipient, rather than as a fair punishment.  The violence therefore continues in an escalating fashion, with each group feeling justified in their actions, egregiously wronged by the other, and with each group inducing future acts of vengeance from their enemies.

The solutions to this predicament include having neutral arbiters--a fair system of policing and justice, empowered by a neutral and fair government which has a motive of minimizing overall harm in its citizens.

On a psychological level, a solution is to recognize the cognitive biases which lead to excessive retaliations and excessive justifications for one's own excesses.  Another solution is to recognize the need for neutral mediation to help resolve ongoing conflicts.

Communalism, tribalism, or nationalism are understandable, common human experiences.  Early human culture required a cohesive sense of protecting one's fellow villagers from attacks from neighbours.  Yet, tribalism fosters patterns of revenge, predation, and dominance-based aggression on a group level.  Having separate tribal cultures, often with language and geographic barriers, is a barrier to empathy for outsiders, particularly if a cycle of warfare has already begun.  We see this type of aggression on a large and small scale, all around us.  In some cases it is playful, as in sports teams from different communities.  Gang behaviour in large cities has a tribal quality, with battles over control, protection, predation of resources, and "honour."   But entire nations behave this way.  We subjectively have an urge to enjoy national identity, but we have to be wary of the violent associations of this mindset.

An approach to this issue is to expand our "circle of empathy," and to view those from other groups as partners rather than enemies.   I suspect the healthiest vestige of nationalism that we can safely keep is to have sports teams.  I think this is also a reason to support free, fair international trade.  Protectionist policies must be based on a notion that there is an "us" and a "them".  But it is fair to view everyone in the world as part of "us" at this point.

Nationalist conflict is one of the most devastating factors causing worldwide violent death and suffering through the ages.

It is for this reason that I support the idea of having international sports events -- I believe that this is a symbolic peaceful sublimation of nationalistic conflict, transforming this type of tension into a playful harmless talent show.   The economic indulgence of such events, such as the Olympics, is an understandable complaint, but I think the pursuit of such playful, peaceful activities is very important.

5)
Sadism  may seem like a rarity, relevant only to extreme cases.  But smaller forms of this issue can occur in communities or in one's inner life.  The driving force in sadism is addictive:  repeated behaviours, even if extremely harmful, can lose their aversive or "taboo" character through repetition, and even lead to addictive pleasure, associated with excitement, relief of tension, etc.  This phenomenon can occur in personalities which had previously been quite "normal."    Pinker does point out the likelihood that psychopathic personality--a pathological lack of sympathy for others-- is a risk factor for sadistic behaviour, and that those with this type of personality are more likely to be attracted to occupations in which they could indulge their violent predilections.  In the book, he does not address the environmental or social causes of psychopathy, though alludes to this problem being at least to some degree a neurobiological variant with heritable aspects, and not entirely due to environmental adversity.  In any case, not all psychopaths end up becoming violent sadists, and not all sadists are psychopaths. 

 In depressive states, various forms of physical and figurative self-injury can become sources of relief, and lead to an escalating pattern of violence against self.   This is not "sadism" but it could be considered as arising similarly, as an addictive habit to which the person becomes tolerant and desensitized, leading to a craving for more and more highly destructive behaviour. 

A solution to this issue is to focus on prevention, and to recognize and avoid risk factors.  In a police or military setting, for example, it needs to be recognized that maltreatment of hostile prisoners can occur and escalate through this process.  Abuses of this kind are not some kind of bizarre perversion, but stem from failure to include judicial safeguards adequately to prevent the police or prison guards from getting involved in an addictive habit of maltreating others.  This can be challenging, because many of the prisoners may have behaved in a terrible way themselves (e.g. violent criminals) and so the initial aggressive responses to them may be approved by everyone involved.

In a personal setting, prevention is also important.  Self-injury often begins secretively, without the addictive risks being appreciated, and by the time the problem surfaces to others, it has become an entrenched habit.  At this stage, approaching it as a potentially lifelong addictive risk becomes necessary, with a variety of psychotherapeutic strategies employed.  For those who engage in sadistic behaviour towards others, I think society should be equipped to approach them as permanent risks to others' safety.   This does not necessarily mean longer prison terms, etc. (though this may be necessary in some instances) but I think it does at least mean longer-term societal scrutiny for protection of others.  

6)
Isolation is a risk factor for violence due to a tendency to form a stronger ingroup, view outsiders as a threat, lack the communication or language to resolve disputes peacefully with outsiders, and to lack the advanced education that could bolster diplomacy, empathy, or self-control.

During early human history, groups existed in relative isolation from each other.  Today, groups which are more geographically isolated (e.g. in remote mountainous areas) tend to have much higher rates of violence, as well as less education.  With the advent of modern communication and transportation technology, isolation on this level does not ever have to be as absolute as it has been in the past.  Yet, some groups may deliberately foster isolation, even when they live in large cities.  I think it is important to foster widespread community interactions between isolated groups.  

On a personal level, isolation is likely to magnify suspicion towards strangers, leading to exaggerated negative reactions to others' behaviour.

Psychologically, problems with isolation may be due to social anxiety, depression, or psychotic paraoia, but the isolation itself becomes part of the vicious cycle of symptom exacerbation.

Every person or community may have a certain "set point" for healthy engagement with others, e.g. some people are more comfortably gregarious than others, but I think some type of social practice and engagement is necessary for the health of individuals and communities. 

On a practical level, learning to speak other languages and customs lessens the isolative boundaries between people.  As a strategy of personal development, it could therefore be healthy to learn other languages, to travel to different countries, and to experience and learn respectfully about other cultures.  Treatment of underlying symptoms, such as paranoia or social phobia, can of course be important. 

7)
Authoritarianism evolves naturally from the most ancient origins:  stronger members of a group will dominate and assume leadership powers.  This factor fits closely with the ideological dynamics of aggression.  Those who challenge the authoritarian leadership can be subject to severe aggression.  One of the perpetuating factors for this dynamic includes the cognitive illusion that everyone supports the authoritarian leader or the authoritarian principles.  Even those who quietly dissent may be so fearful of reprisal that they will act to support the leader, and even punish other dissenters to prove it.  An analogous cognitive distortion is the belief among college students that the majority of their peers enjoy binge drinking--this belief normalizes such behaviour, and causes more people to engage in it because they erroneously thought it was an accepted norm.

A protection against this dynamic is fostering a politically open democracy with freedom of speech.  On a personal level, I think it is healthy and protective to question authority as an intellectual norm.  This includes not only teachers and professors, but also religious teachings.  Authoritarianism that is couched in religious dogma can seem so "sacred" that challenging it would seem disrespectful or like a taboo, thus leading to terrible unchecked excesses and distortions justifying violence or other harms and suppressing intellectual growth.

I had assumed that there would be a universal affirmation of the desirability of multi-party democracy throughout the world.  Yet, I have recently been looking at the PewResearch Global Attitudes Project surveys, including a poll done in 2009 (well before the recent conflicts in Russia and Ukraine).  (link)

This survey shows that people in Russia and several former Eastern-Bloc countries such as Hungary, have had a huge reduction in their enchantment with the idea of democratic government, beginning long before the recent conflicts.   Ukrainians gave some of the lowest ratings of all, regarding attitudes towards democracy, freedom of speech, etc.    I suspect that a major reason for this has been that the democratic changes in these countries have been laden with a lot of corruption, instability, and economic problems.

This is reminiscent of what Pinker described in post-colonial African states, which experienced a large surge in violence rates after declaring independence.  This does not at all mean that colonialism was "good," but rather that the benefits of democracy and societal freedom can only come after a state has become stable in terms of economy and political organization.   The period after major political upheavals can be relatively anarchic, and economically harsh, leading to a steep decline in morale for the population. 


8) 
Ideology can lead to extreme violence, through offering a cohesive set of beliefs which bind an ingroup harmoniously, often with a utopian goal, leading to a rationalization to destroy outgroups. Utopian goals can sound attractive, but often the enactment of these goals involve suspension of the other elements of societal growth and non-violence, such as fairness, justice, empathy for outgroup memebers, etc.  Those who commit catastrophic acts of violence within an ideological framework may understand their actions to be normal or just, and may easily dismiss complaints that their actions are wrong.     Our recent history is full of examples of this type, including Nazi Germany.

Unfortunately, there are many examples in history of religious ideologies leading to extreme violence in this way, continuing with examples in today's news.

A prevention for this type of problem includes education, including in the arts and humanities, a commitment to ecumenical approaches in theology (regardless of one's religious orientation), and a commitment to have diplomatic relationships with those having different ideological viewpoints.

I think these preventions apply on a large scale in societies, but also on a personal, individual level.

9)
Intelligence, the greatest talent of humankind, has the power to defuse conflict through negotiation, wise strategizing, and improved empathic understanding of one's opponents.    Cognitive biases are not eliminated by intelligence alone (as Kahneman has shown), but the capacity to employ reason rather than rage to solve problems is enhanced by intellectual training.  Such intelligence has grown over the generations, as Pinker has shown.  This is likely due to better education, and exposure to a more stimulating global cultural milieu.  Unfortunately, many in the world lack access to the basic resources or freedoms to develop their intellect in this way.  Part of global peacemaking must therefore include a strong emphasis on universal access to education.

Intelligence, of course, also permits a higher chance for employment, prosperity, and diverse leisure activities, all of which reduce risks for violence and other harms.

On a more immediate, personal level, intellectual development could be framed as a component of psychotherapy.  This could work not only as a way to focus the brain on activities apart from depressive rumination, but also could strengthen faculties of the mind which could act as skilled "negotiators" to calm the self-injurious impulses which can occur in depression or anxiety.  Some of the CBT literature shows that this type of therapy works better in those who are more highly educated.  Conversely, I suspect that better education and intellectual training can make psychotherapy work better.

The Better Angels of Our Nature: Why Violence Has Declined, by Steven Pinker: A Book Review, Part 1

I have just finished Steven Pinker's book, The Better Angels of Our Nature: Why Violence Has Declined

I think it is a masterpiece of scholarship and research, combining the fields of psychology, history, political science, anthropology, economics, and statistics to contribute a hopeful affirmation about the progress the world has made to reduce violence and to improve quality of life.

My favourite scholarship is the type which combines multiple fields in this way!  

In these posts I would like to briefly summarize the book, and to reflect about ways to apply some of Pinker's insights to the practice of psychotherapy.

I see there has been mostly strong praise for this book among critics, but predictably there has been some controversy.    Cultural groups which still have strong authoritarian, communal, tribal, sexist, or fundamentalist values may find some of Pinker's conclusions to be critical of their way of life.  Mind you, he does show that in almost all such subcultures, such as conservative groups in the U.S., there have been positive changes, for example towards affirming rights for previously disenfranchised groups.  It is just that these changes usually lag a decade or two behind such changes in the rest of the population.  An attitude about women's rights or gay rights that would have been called "liberal" in 1970 would be considered a norm in many conservative groups today. 

Pinker shows that most elements of religious belief and practice have had negative impacts on rates of violence and war, due in part to causing an ingroup mindset, which tends to undervalue the human worth of non-believers, therefore facilitating maltreatment of those with a different faith.    Also most religions have a type of authoritarian structure, including about the concept of divinity itself.  The notion of an afterlife can not only model infinite punishment ("hell") as a supposedly fair possibility for an individual based on offenses such as "disbelief" but could encourage such an attitude of infinite punishments in approaching other individuals or cultures.  Conversely, with infinite reward ("heaven") in the picture, perhaps with simple criteria such as "belief" to be the ticket of entry, this could be experienced as a license to engage in many destructive acts during life while minimizing the relative value of earthly justice.

Other critics question his statistics, but here I think he has been very impressively thorough.  His statistics do not at all imply that violence has miraculously disappeared in modernity, and very clearly do not imply that the most horrific possibilities of violence -- such as the scale of events which happened in World War II -- cannot happen again.  In fact, his discussion of statistical power-law distributions modeling violent conflict gives rise to great concern:  based on this distribution, one can expect an arbitrarily large and devastating conflict to occur in the future, since this type of distribution is "tail heavy" statistically.  His analysis does give reason to be hopeful, though--the underlying causations and probabilities which become the parameters of these statistical patterns are themselves declining.

An example of a power-law distribution is the length of words that would be generated on a typewriter if one were to type on the keys and the spacebar randomly.  Typing the spacebar would separate individual words.   The length of the word would represent the magnitude of  (or loss of life from) a violent conflict. With this analogy, a conflict happens every time the spacebar is pressed. One could see that short, small conflicts would be most common, but that longer, larger conflicts could happen periodically, though less frequently, in a random pattern.  It is disconcerting that this type of distribution can have an infinite expected value, representing total destruction of the population.  As we know, this is actually a possibility in the nuclear age.

But Pinker's thesis also shows that the parameters of this imaginary typewriter are changing--with time, the typewriter is gaining more and more keys (just like Microsoft keyboards!).  This causes the relative risk of pressing the spacebar to gradually decrease with time   Also, metaphorically, Pinker is showing that the information content of each key is increasing, so to speak, causing fewer keys to need to be pressed at all.    Just as with computer keyboards, we are even developing ways to interact without using keyboards at all (e.g. with mice, or voice commands).  The mechanisms he shows for these changes in risk parameters are increased education, intelligence, an expanding circle of empathy, an expanding force of reason, improved human rights (e.g. for women, racial minorities, and people having different sexual orientations), free and fair trade,  and improved stable government (what he calls the "leviathan").

How long does it take for psychotherapy to work?

There are various research articles done in the past which describe rates of change in psychotherapy patients, some studies for example describing a plateau after about 25 sessions or so.  I find these studies very weak, because of the multitude of confounding factors:  severity and chronicity are obvious variables, also the type of follow-up assessments done.

In the CBT literature, a typical trial of therapy is perhaps 16-20 sessions.

In light of our evolving knowledge of neuroplasticity, and our breadth of understanding about education & learning, it seems to me that the most important variable of all is the amount of focused, deliberate practice time spent in a therapeutic activity.  Oddly, most psychotherapy studies--even CBT studies--do not look at how many hours of practice patients have done in-between therapy appointments.  This would be like looking at the progress of music students based on how many lessons they get, without taking into account how much they practice during the week. 

I have often compared psychological symptom change to the changes which occur, for example, with language learning or with learning a musical instrument.

So, I believe that a reasonable estimate of the amount of time required in psychotherapy depends on what one is trying to accomplish:

-Some types of therapeutic problems might be resolved with a few hours of work, or with a single feedback session with a therapist.  This would be akin to a musician with some kind of technical problem who needs just some clear instruction about a few techniques or exercises to practice.  Or it might be akin to a person who is already fluent in a foreign language, but needs a few tips from a local speaker about idioms, or perhaps some help with editing or grammar in a written text.

-Many more therapeutic problems could improve with perhaps 100 hours of work.  This would be like learning to swim or skate competently if you have never done these activities before.  Regular lessons ("therapy") would most likely speed up your rate of progress substantially.   But most of those 100 hours would be practice on your own, unless you're okay with the progress taking place over a year or more.   With the language analogy, think of how fluent you might become in a foreign language with 100 hours of focused, deliberate practice.  For most of us, this would lead to an ability to have a very simple conversational exchange, perhaps to get around in the most basic way in another country.  

-A much larger change is possible with 1000 hours of work:  with music, one could become quite fluent but probably not an expert.  With a foreign language, comfortable fluency would probably be possible, though probably still with an accent and a preference for the old language.
 
-With 5000-10000 hours of work (this is several hours per day over a decade or more) one could become an expert at a skill or a language in most cases.  

In psychotherapy, another confound though is whether the times in-between "practice sessions" lead to a regression of learning.  An educational analogy would be of practicing math exercises an hour per day with a good teacher, but then practicing another 8 hours a day with another teacher whose methods contradict the first.  Often times, learning will still take place with this paradigm, but it might be much less efficient.    Persistent mental habits, in the context of mental illnesses, can be akin to the "second teacher" in this metaphor, and unfortunately they do tend to plague people for many hours per day.

This reminds me of the evolving evidence about stroke rehabilitation & neuroplasticity:  substantial brain change can happen in as short a time as 16 days--but it requires very strict inhibition or constraint of the pathways which obstruct rehabilitation. (note: 16 days of continuous "immersion" = 16*24 = 384 hours!)  In stroke rehabilitation, the neuroplasticity effect is much more pronounced if the unaffected limb is restrained, compelling the brain to optimize improvement in function of the afflicted limb.  Here is a recent reference showing rapid brain changes following limb immobilization: http://www.ncbi.nlm.nih.gov/pubmed/22249495

In conclusion, I believe that it is important to have a clear idea about how much time and deliberate, focused effort are needed to change psychological symptoms or problems through therapeutic activities.  A little bit of meaningful change could happen with just a few hours of work.  In most cases, 100 hours is needed simply to get started with a new skill.  1000 hours is needed to become fluent.  And 5000-10000 hours is needed to master something.  These times would be much longer still if the periods between practice sessions are regressive.  In the case of addictions, eating disorders, self-harm,  or OCD, for example, relapses or even fantasies about relapse will substantially prolong the time it takes for any therapeutic effort to help.  Of course, it is the nature of these problems to have relapses, or fantasies about relapse--so one should let go of the temptation to feel guilty if there are relapses.   But if one is struggling with an addictive problem of this sort, it may help to remind oneself that the brain can change very substantially if one can hold onto to quite a strict behavioural pattern for the hundreds or thousands of hours which are needed.

As a visual reminder of this process, start with an empty transparent bottle, which can hold 250-500 mLof liquid (1-2 cups), and which can be tightly sealed with a small cap.  Add one drop of water every time you invest one hour of focused, deliberate therapeutic work.   The amount of time you need to spend in therapy depends on your goal.  If the goal is total mastery--then you must fill the entire bottle.  If simple competence in a new skill is an adequate goal, then you must fill just the cap of the bottle.  If there are activities in your day which contradict the therapeutic work, it would be like a little bit of water leaking out of your bottle.  So you must also attend to repairing any "leaks."  But every hour of your effort counts towards your growth.

Psychiatry and Linguistics

The history of spoken and written language is a very interesting field of study.  The manner in which languages evolve over time is similar, literally, to the way in which species evolve (languages do evolve much more rapidly than species).  It is interesting to look at a kind of linguistic evolutionary tree, to see the parallels and differences alongside a genetic evolutionary tree, say of Indo-European languages in comparison to mitochondrial or Y-chromosome haplotype analysis in Eurasian groups.

Styles of language, and of word choice, etc. are certainly influenced by the culture of the day.  It would be interesting to consider the degree to which word choices affect individual psychology.  Some modern feminist thinking has certainly looked at the issue of language issues having important elements of psychological effects, particularly if the language itself is biased towards being sexist.  This is a big area, one which I'd be interested to learn more about.

Another aspect of linguistics has to do with the multi-sensory nature of language perception.  I find this very interesting, in expanding our understanding of the way the mind works in general:  words on their own may be perceived or understood in different ways intellectually (this is an issue often discussed by literary scholars), but the manner in which words are perceived is also influenced very directly by core neurologic processes.

For example, I recently discovered the existence of a very powerful perceptual phenomenon called the "McGurk Effect."   Here are a few examples from YouTube:
http://www.youtube.com/watch?v=DsdyE491KcM&feature=related
http://www.youtube.com/watch?v=aFPtc8BVdJk&feature=related
If you watch the video while listening to the speaker pronounce a syllable, it sounds completely different from when you close your eyes and just listen without watching.  The phenomenon demonstrates how powerfully visual input changes how we perceive an auditory stimulus.  I was surprised to find how overpoweringly strong the effect was, how difficult it is to somehow "over-ride" it.

Other linguistics research demonstrates that other sensory modalities, including tactile, also have strong effects on language perception.

As an extension to psychiatry, and to the general workings of the mind, I think it is true that many different perceptual and psychological inputs have very strong effects on the way we perceive other stimuli.  In social exchanges, there may be a wide variety of inputs which we are not consciously aware of, which could be substantially affecting our experiences.  In most cases, these other inputs assist us in understanding better.  The purpose of having one sensory modality influence another is to bolster the input from both, so as to facilitate understanding.  This is the foundation for how lip-reading works, for example.   But if one input is, without our knowledge, giving opposing information compared to another input, then this could lead to a very problematic behavioural cycle.

I think such phenomena are likely to happen in many anxiety disorders, for example, in which the anticipatory anxiety, and resultant physical and emotional tension, are likely to cause one's perceptions of benign social stimuli to become exaggeratedly negative.  This is happening not just on an intellectual level, but arguably on a core perceptual level, akin to the McGurk effect.  Similar perceptual distortions are likely to happen in other psychological states, such as depression.  The cognitive theory of depression centres around so-called "cognitive distortions," but I think it is important to expand this concept to admit that the phenomena could be powerful "cognitive-perceptual" distortions, which could require a lot of disciplined work to overcome.  Without acknowledging the strength of this phenomenon, frustration could quickly set in, just as it would if you were to simply practice hearing McGurk-style syllables without knowledge of the McGurk effect.

Psychiatry and Economics

I've alluded to the field of "behavioural economics" in other posts.  I think this is a very interesting extension of social and motivational psychology.

I think that a broad analogy can be made between economics and psychiatry:
the phenomenon of an economy is similar to the mind, or to one's life, in a variety of ways:
1) there are engines which drive the economy, in the form of productivity.  Economic productivity may be measured by goods or services generated by the population.  Life productivity includes various tasks of developmental "work".
2) There is a relationship between "supply" and "demand" which changes the valuation and flow of productivity.
3) Currencies become symbolic short-cuts to exchange goods or services; emotional or behavioural "currencies" can be short-cuts in to obtain needs in the community or in relationships.
4) Problems in an economy could occur at many different levels in the system:  productivity failure due to a technical, external problem (e.g. a natural disaster), a failure to exchange or trade freely, a symbolic or regulatory system which goes out of control despite integrity in the rest of the system (e.g. stock market crashes).  In the economics of mind, there could be core external problems (e.g. a neurological disorder), but there could certainly also be problems "trading freely."  Heightened neurotic defenses could be compared to a lack of "free trade," where healthy inner resources cannot be shared, not with other parts of oneself, nor with others.  Such phenomena stunt an economy, even if the core capacity for productivity is strong.  A "stock market" crash, similarly, could occur in the mind, if regulatory mechanisms in one's mind run wild, while losing touch with a moment-to-moment sense of self or present. 
5) Borrowing could, one the one hand, be a powerful means to accomplish tasks that would otherwise be impossible (e.g. buying a house).  Refusal to borrow limits capacity for growth.  But if debt cannot be managed, it leads to an economic instability, reduced autonomy, and ultimate failure (bankruptcy).  Similarly, in one's mind, risks need to be taken to grow, and one needs to borrow from others and from the community in order to develop oneself.  Refusal to borrow limits what is possible.  However, over-borrowing, and accumulation of social & emotional debts, leads to a cascade of chaotic effects. 
6) Investing is a means of taking a risk of giving one's resources away, with the hope that the community will prosper as a result, and return the investment prosperously.  Emotional and social investments are risks taken which, on the one hand, are immediately depleting, and which may cause permanent losses (e.g. with unfruitful actions are relationships) but which permit the possibility of substantial growth in one's own life, while also allowing resources for the community to grow (emotionally or socially) around you. 

Much in the field of economics include sophisticated mathematical analysis of the energy dynamics in an economic system, accounting for the many variables at play.  It would be interesting to apply some of this analysis to psychological dynamics.  Behavioural economics is more psychology than economics, at this point.  It would be curious to have more of the leaders in the study of mathematical economics apply some of their ideas to "psychological economics."  

Psychiatry & Architecture

This is the first in a series of posts in which I'd like to discuss figurative or literal comparisons and overlaps between psychiatry and other fields of study. 

Architecture could be considered a science and an art--a field with many technical elements, but with an over-riding importance given to esthetics, expressiveness, and community relationships.

Ideas in psychiatry could be considered "architectural" in the sense that it is important to have an overall sense of a plan, with a clear sense of purpose.  Even with good technical skills (e.g. to relieve a symptom),  work in psychiatry, or in life progress, may be unsatisfying if there is no attendance to the larger sense of purpose in the life's structure.  Part of the purpose is "esthetic," but part has to do with identity, interaction with community, originality, and expressiveness.  This is similar to the architectural considerations involved in planning and developing a new physical structure. 

As in architecture, many very good ideas could be generated to develop one's life, but the ideas must also be technically sound, and supported by good engineering.  Many life plans have dangerous weaknesses in the foundation, so to speak, or may be hindered by untreated symptoms.  So, a sound architectural plan in psychiatry or in life management must include both esthetic or artistic elements, as well as good structural support.

A Learning Model of Psychological Change: the necessity of work & practice

It requires a great deal of work to bring about psychological change.

The brain is a dynamic organ, its development influenced by genetic predisposition combined with environmental experience.  Repeated environmental experience sculpts the brain, altering the strength of neuronal connections, neuronal activity, neurochemistry, and even neuronal growth or survival.

Various environmental adversities obviously predispose the brain to generate psychological symptoms, including specific incidents of trauma or neglect.

The manner in which adversity changes the brain is similar to the manner in which the brain changes in response to any other sort of experience:  sometimes there is sudden, intense change which can happen in an instant (e.g. a traumatic brain injury), but most often the brain changes gradually, after many repetitions of similar stimuli or similar inner processes.

Some environmental adversities are repetitive over months or years.  But often times the repetition which does further harm is generated by the brain itself:  in response to a problem, the brain's repetitious analysis and revisiting of the problem ends up causing consolidated change and ongoing symptoms. A great deal of the harm caused by specific instants of trauma is caused by the brain's reaction months or years after the trauma is over.  This reaction is akin to an autoimmune disease, in which the body's attempts to fight off disease end up causing inflammation, pain, and tissue damage. 

A symptom, such as anxiety or depressed mood, once generated from any cause, may lead to a cascade of brain changes which perpetuate and intensify the symptom.  The behavioural withdrawal which results from anxiety or depression changes the potential experiences the brain may incorporate in order to heal itself.  Even without overt behavioural withdrawal, an anxious or depressive state may cause the brain to perceive normal or pleasurable stimuli as dangerous, negative, boring, or unpleasant.   Each time this experience occurs, the brain changes further into a state of more deeply consolidated anxious or depressive disorder.  The theory of cognitive-behavioural therapy insightfully recognizes the role of thoughts as part of a cascade of phenomena perpetuating psychological illness.  Recurrent hostile, reflexively critical, cynical, pessimistic or negative thinking may at times have intellectual or philosophical validity; however, such thoughts, if highly recurrent, teach and sculpt the brain to make such a style of thinking an entrenched habit.  Such habits of thought are obvious causes for depression and diminished quality of life.    

My point here is to describe the brain as a "teachable" organ.  It is changed and sculpted by experience.  The source of this experience may be from the external environment or from the self-generated inner environment of the brain.   The degree to which the brain is sculpted by experience depends on the intensity of the experiences, multiplied by the time or frequency the experiences repeat themselves.

 In this regard, as I've stated before, the brain and its experiences are analogous to a growing garden, or a forest:  changes require time, care, knowledge about requirements, and energy.


Therapeutically, it is very clear to me that much work must be done in order to effect significant, lasting brain change. Likewise, a growing garden requires frequent care, particularly if there are adverse conditions caused from within (e.g. depleted soil, weeds) or from without (e.g. harsh weather, vandalism).  

The neurochemical environment can be an obstacle to brain change, in the same sense that abnormal soil chemistry may thwart the most earnest efforts of a gardener.  The "abnormal soil chemistry" may itself have been caused by an imbalanced garden ecology over many years, perhaps by genetic predispositions of the plants, and may conceivably be remediated and prevented in the long term by healthy gardening practices, yet an immediate external aid could be an immensely helpful catalyst to help these changes occur more easily and quickly.   Likewise, psychiatric medications can often be helpful catalysts for change.

But the key ingredient for brain change is experiential.  The type of experience capable of changing the brain substantially must be strong enough (i.e. it must employ a significant degree of the brain's capacity for attention, thought, feeling, and sensation, rather than simply being a passive or background activity), and must be frequent enough (i.e. it must occur regularly over a long period of time).

These requirements for experiential change are, as I've claimed before, similar to the requirements needed for learning a new language, or a musical instrument.

Without daily practice, therapy experiences which involve only one, or a few, appointments per week, are unlikely to cause significant psychological change, for the same reason that a language or music class once or twice a week will not lead to much language or music learning without doing daily homework.   The classes may be helpful or inspiring guides, but most of the change or learning will occur due to many hours of hard work, practicing, in-between classes.

Studies of different therapeutic strategies for treating psychological symptoms usually neglect to assess the most obvious and powerful source for change:  the amount and quality of the practice done.  It seems to me that most any style of therapy could work quite well (some slightly better than others, depending on the situation), provided that a great deal of disciplined work and practice takes place to learn new skills, and to effect change in the brain.

The analogy of musical practice leaps to mind again, in which quantity and repetition are important for learning, but also "quality."  To practice something passively, carelessly, or inattentively is often ineffectual, or sometimes even counterproductive, since one may be inculcating an unwanted habit.  Also, some types of practice may be excessively mechanical, or may be veering off a desired course too easily.

I am reminded of the "Suzuki" method of music education, which I think is wonderful, for the following reasons:
1) it encourages one to start young (i.e. at any age or level of ability)
2) it strongly encourages "playing by ear", listening frequently to recordings with strong attention to perceiving sound and tonal quality; this leads to a stronger and more rapidly developed appreciation for esthetics, as well as less dependency on external cues such as printed music.   The therapeutic analogy could be of  inviting frequent indirect involvement from a therapist or therapeutic system, rather than doing all "homework" completely on ones' own.
3) it strongly encourages group practice & performance, right from the beginning. This teaches not only solo musicianship, but also following and playing well with others, enjoying others, cooperation, being in a leadership role, having confidence with performance, and sharing one's gifts with others.   Also, practice is encouraged to be not just a solitary activity, but something which can be done with family or loved ones.  Therapeutically, I think it is strongly desirable to incorporate psychological work into group, family, and community settings.  
4) it emphasizes the importance of good posture.  Therapeutically, I think a fairly strict and disciplined framework to practice psychological techniques is healthy and reduces the likelihood of acquiring unhelpful habits.  On a literal level, I think a balanced exercise routine is psychologically healthy, including cardiovascular or strength training, sports, or a "postural" exercise such as yoga. 
5) it emphasizes the need for a lot of repetition.  Therapeutically, it may be necessary to practice techniques thousands of times, over a period of months or years, in order for them to become fluent.   Repetition should never be undertaken in a dull, mechanical way -- it needs to be infused with careful, reverent attention -- but it is absolutely needed in order to master anything. 

I challenge all those wishing to change longstanding psychological problems to frequently renew commitments to work hard, and to translate these commitments into a disciplined schedule of daily practice.  It may be that there are symptoms of  tiredness, amotivation, apathy, or a very negative or painful reaction to a broad variety of daily life experiences; these symptoms can prevent engagement with commitments, and can hinder the capacity to engage in disciplined work habits.  Also, the life stressors (work, money, relationship problems, etc) can take up so much time and energy that there is not much left to do regular psychological work.  Perhaps part of the therapeutic process at this stage is to problem-solve around ways to reduce stresses, reduce some of the symptoms, bolster energy, etc. as prerequisites to establishing a work plan.  Another view of this issue is that the "work" alluded to here could take place within any type of life stressor, it does not necessarily require a lot of extra time separate from other activities of daily living.

Olympics & Psychiatry


The Olympic games cost billions of dollars to prepare for, and to host. Therefore, it has been a subject of controversy, particularly because so many people (both globally, and in the local communities near the Olympic sites) are suffering with homelessness, poverty, lack of opportunities for therapy, education, recreation, healthy community, etc. There is understandable criticism that those billions could have been better spent addressing these serious social problems directly.

A few things in particular bother me about the Olympics: one main corporate sponsor is a soft-drink company; another is a fast food company. These companies, in my opinion, contribute to the health problems of millions of people. It is like having cigarette companies as sponsors. The Olympic torch was preceded by a truck with neon lights and dancers boisterously advertising soft drinks...I think this was contrary to the spirit of the event--certainly in bad taste-- and I hope future Olympic organizers can be more health-conscious in considering whom to allow as corporate sponsors.

Overall, however, my opinion is that the Olympics are very healthy, for the following reasons:

1) In these games we have an opportunity for nations of the world to display a type of excellence, and to come together in serious, spirited, but friendly competition. It is a model of sublimating competitive conflict through sport or play, rather than through war. And it is an opportunity for multicultural celebration, in a setting which encourages sportsmanship, generosity, and hospitality.

2) The ethical problem of spending extravagantly while many do not have basic needs met is a very serious one. Here are a few ideas about this:
-Almost any activity could be considered extravagant spending (in terms of money, time, or attention) : much university education does not address the needs of impoverished, displaced, or other suffering individuals. Much in medicine (e.g. transplantation surgery) could be considered expensive extravagance, benefiting a small number of people while others have inadequate basic health care. A great deal of scientific exploration (e.g. the space program) is very expensive, yet doesn't help directly with poverty or world hunger. Investment of time, attention, or money in the arts (e.g. music, theatre, literature, visual arts) could be considered wasteful, since it does not directly help with poverty or homelessness. People could be directed to stop spending time reading novels, going to plays, going jogging, having pets, etc. because they should better be volunteering to assist with dire social problems.
-Regarding the above examples, I think most would agree that these "extravagant" aspects of human endeavour are healthy...it is part of human nature to strive for excellence and for new frontiers (whether this be in space travel, advanced surgery, mathematics, theatre, or sports): it is part of healthy civilization that we allow our attention, time, and money to be invested in these activities. It would induce a type of global psychosocial impoverishment to suppress these activities. The development of a culture which is advanced in terms of arts, sciences, and sports, and which shares its advances with other cultures, is healthy. While these activities may not directly help with social problems, they are part of building a healthier society, which in turn can address its social problems with greater ease and morale.

This social issue has a metaphorical parallel, I think, in individual cases of depression, anxiety, or other psychological symptoms: in a depressed or anxious state, a much greater portion of energy may be invested to meet basic needs. Energy itself may be in short supply, and it may require most of this energy just to prepare food, or to make it through the day. It makes sense to budget energy in such a way that few "extravagances" are allowed. Yet, if this budgeting practice persists for years, it may lead to a perpetuation of a grey, depressed status quo. "Extravagance" may be a necessary part of energy budgeting in depressive states--this extravagance might take the form of energy expenditures which may not seem affordable (e.g. exercising, taking up a new activity, involving oneself in a new community, socializing, taking time away from a hard-to-maintain work schedule in order to volunteer, etc.)---and indeed, such extravagances may sometimes not work out (e.g. efforts to socialize may fizzle, the new activity doesn't work out due to depressive fatigue, etc.). But allowing for extravagances is a type of balanced risk that can permit growth from a depressive status quo.

Suppose a room-mate invites a whole bunch of people to your home, for a lavish celebration. Suppose you are very opposed to this event, perhaps in the context of your room-mate not having done his share of chores regularly for the past 4 years (etc.) ...But suppose also that the guests are themselves honorable, noble people who come from many lands, who are polite, respectful, talented, and interesting. Perhaps in this context it is healthier to set aside one's differences, and to welcome the guests with a spirit of hospitality and celebration.

I think it is great to have the Olympics in Vancouver: I wish all the athletes and spectators a happy, healthy, spirited few weeks of enjoying our community, of enjoying vigorous competition and good sportsmanship. Afterwards, I hope that all of us in the community may enjoy the resources constructed for the games, and that special effort may be made to include those in greatest need.

Becoming a "Self Whisperer"

Well, you may accuse me of having sentimental tastes in film, but I really did enjoy the 1998 movie with Robert Redford, called The Horse Whisperer. It's about a reclusive Montana rancher who has an almost mystical ability to gently connect with and rehabilitate horses (and humans?) who are wild, traumatized, or out-of-control.

Since 2002, a dog trainer named Cesar Millan has called himself "the dog whisperer," and has a TV show, website, and has sold millions of books. His approach is basically one of gentle, calm authority: maintaining clear and consistent boundaries without losing one's cool or becoming excessively punitive. Mind you, I see that there is a little bit of debate about some of his techniques. And it's a bit dicey to apply animal training ideas to humans.

Recently, however, people have been trying to generalize these ideas a little bit, to the subject of parenting. Hence the idea of becoming a "child whisperer." Many parents have unhelpful interactions with their children: perhaps there are behavioural or discipline problems, but often times the parents are losing their cool, the parents are resorting to excessive and ineffective punishments, or the parents are giving a lot of praise but without any discipline. Sometimes the timing of praise or discipline is out of synch with the child's behaviour. Some methods of discipline may be harmful to both child and parent. Sometimes misbehaving children seem to be ruling the house, leaving the parents frustrated and exhausted. An exhausted parent in this situation may end up just spending less and less time parenting, in order to find distractions from the problems, or in order to escape. While respite is necessary, this tactic would of course make the parent-child dynamics even worse.

Here's an article from the New York Times on this:
http://www.nytimes.com/2009/11/22/fashion/22dog.html

I would like to generalize this idea one step further, to consider ways to become a "self whisperer."

This may involve nurturing a sense of calm, gentle understanding and authority over the various forces within your own mind:

-in this sense exercises to relax or meditate need not be considered exercises in tolerating an unhealthy state, but rather exercises to produce a stance of calm, loving, gentle authority, which is ideal in "self-whispering."

-part of the process may involve setting very clear boundaries within your own mind, without becoming excessively punitive, bossy, critical, or authoritarian towards aspects of yourself or others. Various therapy styles can help in this sense, including cognitive-behavioural ideas. Methods of non-harmful self-discipline may need to be learned and practiced.

-it can be important to have "respite", but it will be important "to do activities together" with the more challenging aspects of your mind, to be an effective "self whisperer." There needs to be time for reflective, empathic dialog with self, provided there is a benevolent structure, healthy boundaries, and clear safety rules.

--I'll have to edit this posting a bit, I think it's in a formative stage right now, but I thought I'd put it up here as the start of an idea I found enchanting in the moment--

Physical Warmth promotes Interpersonal Warmth

In an amusing study by LE Williams and JA Bargh, published in Science in 2008, subjects exposed to warm objects behaved in a manner which was more interpersonally warm. Here is the reference:
http://www.ncbi.nlm.nih.gov/pubmed/18948544

In the first experiment described by the authors, subjects in the elevator on the way to the study lab were asked to hold an experimenter's drink cup for a moment, while the experimenter wrote some identifying information down on a clipboard. The experimenter in the elevator did not have knowledge of the study's hypotheses. In the study lab afterward, the subjects were given a brief written description of a person (the same description given to all subjects), and were asked to rate that person in terms of a variety of personality dimensions. The subjects who briefly had held a cup of hot coffee gave personality ratings that were significantly "warmer," compared to the subjects who had held a cup of iced coffee. The ratings for warmth were 4.71 out of 7 for the "hot coffee" group, compared to 4.25 out of 7 for the "iced coffee" group; these differed with a p value of 0.05. "Warmth" in this sense refers to traits such as friendliness, helpfulness, and trustworthiness.

The second experiment was more blinded, in that the experimenters did not know whether the subjects were handling a warm or cold object. This time, subjects were offered a choice of two types of gifts after the experiment: the first type would be for personal use, the second would be a gift for a friend. Those who had handled a warm object were substantially more likely to choose a gift for a friend, rather than for themselves.
Those who had handled a cold object chose a "selfish" gift 75% of the time.
Those who had handled a warm object chose the "selfish" gift 46% of the time.

The authors discuss attachment theory, and suggest that one explanation for these findings, on a neurobiological level, is that the insular cortex in the brain is responsible for processing information about both physical and psychological warmth, therefore the two types of warmth perception may influence each other.

I find this type of cross-sectional social-psychological research fun and a bit lighthearted, but often containing kernels of wisdom.

It would be interesting to do similar studies of this sort, but with different groups of subjects who are stratified according to interpersonal style, depressive symptoms, etc. Perhaps there are subjects who are most sensitive to these environmental effects.

I'm amused and delighted, in any case, that figurative or "metaphorical" warmth seems to match up with literal or physical warmth. A nice meeting of the metaphorical with the literal. Perhaps this is typical of what the brain does.

In any case, this little piece of evidence further supports the recommendation to do sensually pleasing, "warmth-oriented" activities, as part of a regimen for maintaining psychosocial health. There may be something in particular about heat which could be therapeutic. Hot baths are anecdotally helpful for relaxation, pain relief, and to promote deeper sleep. I've encountered a few examples in which people found saunas quite helpful for seasonal depressive symptoms. Maybe a very warm, cozy sweater can be helpful for your mental health, and even have positive effects on others!

Here are references to a few studies showing improvement in insomnia following hot baths:
http://www.ncbi.nlm.nih.gov/pubmed/10566907 {a 1999 study from the journal Sleep, showing improvements in sleep continuity and more slow-wave sleep earlier in the night, in older females with insomnia who had 40-40.5 °C baths 1.5-2 hours before bedtime}
http://www.ncbi.nlm.nih.gov/pubmed/15879585 {a 2005 study in the American Journal of Geriatric Psychiatry showing improved sleep in elderly people with vascular dementia, following 30 minute baths in 40°C water, 2 hours before bedtime}

A precipitant of some seasonal depression, at least in Canada, may be not only the darkness but the cold. The cold may lead not only to a disinclination to go outside, but also to a less generous or a "colder" interpersonal stance, which would further perpetuate a depressive cycle. This is another reason to heed that advice mothers often give young children, to dress warmly in the winter.

Here is a link to the abstract of a study from Japan, published in Psychosomatic Medicine in 2005: http://www.ncbi.nlm.nih.gov/pubmed/16046381

In this study, mildly depressed subjects were randomized to receive one of two treatments, 5 days per week, for 4 weeks, in addition to daily physical and occupational therapy:
1) "thermal therapy" in a 60 °C sauna for 15 minutes, followed by 30 minutes wrapped in a blanket, in a 28 °C room.
2) "non-thermal therapy" of 45 minutes in a 24°C room

The thermal therapy group had a 33% reduction in psychological symptoms, compared to a 14% reduction in the non-thermal therapy group.
The thermal group had a 42% reduction in somatic complaints, compared to an 8% reduction in the non-thermal group.

The research literature on this subject is quite limited, but there is some evidence that warmth--physical and psychological--is therapeutic!
