What implications does a livewired brain have for personal development?

 

I was pondering this question while reading David Eagleman’s book, Livewired: the inside story of the ever-changing brain. Eagleman is a neuroscientist, writing about neuroplasticity for a popular audience. My interest in brain plasticity was aroused over a decade ago when I read Norman Doidge’s book, The Brain that Changes Itself, and speculated about some implications of his assertion that “to keep the mind alive requires learning something truly new with intense focus”.

Eagleman prefers “livewired” to “plastic” because the latter term may bring to mind plastic molds rather than flexibility. He suggests that we need the concept of liveware “to grasp this dynamic, adaptable, information-seeking system”.

By the way, Eagleman’s book has left me thinking that in 50 years’ time, people who are shown the above cartoon will still be able to see the humor in it.

The livewired brain

In my view, the most important point that Eagleman makes is that the human brain arrives in the world unfinished: “despite some genetic pre-specification, nature’s approach to growing a brain relies on receiving a vast set of experiences, such as social interaction, conversation, play, exposure to the world, and the rest of the landscape of normal human affairs”.

Experiences during early childhood are to a large extent determinative. If infants don’t have appropriate social and sensory interaction, their brains become malformed and pathological.

As brains mature, neural maps become increasingly solidified. As brains get good at certain jobs, they become less able to attempt others. Adult brains keep most of their connections in place to hold on to what has been learned, with only small areas remaining flexible. Nevertheless, even in the elderly an active mental life fosters new connections.

Eagleman distills the main features of livewiring into seven principles:

1. Brains match themselves to their input, e.g. when a person is born blind the occipital cortex is completely taken over by other senses.
2. Brains wrap around the inputs to leverage whatever information streams in. It is possible for one sensory channel to carry another channel’s information, e.g. with appropriate equipment, the brain is able to learn to use information coming from the skin as if it is coming from the eyes.
3. Brains learn by putting out actions and evaluating feedback, e.g. that is how we learn to communicate with other people, how we can learn to control machinery, and how a damaged spinal cord can be bypassed using signals passed directly from a brain to a muscle stimulator.
4. Brains retain what matters to them; flexibility is turned on and off in small spots based on relevance; what is learned in one area is passed to an area in the cortex for more permanent storage; the cortical changes involve the addition of new cellular material; brains have a different system for extracting generalities in the environment (slow learning) and for episodic memory (fast learning). “Everything new is understood through the filter of the old.”
5. Brain lock down stable information. Some parts of the brain are more flexible than others, depending on the input. Brains adjust themselves depending on how you spend your time. When learners direct their own learning, relevance and reward are both present and allow brains to reconfigure.
6. Plasticity arises because different parts of the system are engaged in a competitive struggle for survival. Competition in the brain forest is analogous to the competition between trees and bushes in a rain forest. The principles of competition poise the brain “on the hair-trigger edge of change”.
7. Brains build internal models of the world; by paying attention, our brains notice whenever predictions are incorrect and are able to adjust their internal models.

Eagleman argues that the computer hardware/ software analogy tends to lead people astray in thinking about brain function. He suggests that as neurologists illuminate the principles of brain function, those principles will be gainfully employed to create self-configuring devices that use their interaction with the world to complete the patterns of their own wiring.

The book ends with this thought:

“We generally go through life thinking there’s me and there’s the world. But as we’ve seen in this book, who you are emerges from everything you’ve interacted with: your environment, all of your experiences, your friends, your enemies, your culture, your belief system, your era—all of it.”

That could be interpreted by social engineers as an invitation to seek to modify our brains by shaping our environments. I prefer to see it as an invitation to individuals to think about their belief systems and the choices they make that influence their personal environments because their beliefs and choices can have a profound impact on their own personal development. I will explain later the links between personal environment, social capital and individual flourishing.

The idea that individuals can make choices about their personal environments implies the existence of free will. Eagleman is somewhat skeptical about the existence of free will but he speculates that it may be a property of the whole brain as a complex network or system.  He acknowledges that organisms display the property of free will in their interactions with their environments. Self-direction seems to be implicitly acknowledged in the discussion of some topics in Livewired.  For example, there seems to be implicit acknowledgment that individuals may choose what they practice in the discussion of the ten-thousand-hour rule concerning the need for practice to acquire expertise. Self-direction also seems to be implicit in choices many elderly people are making to keep their brains active.

More fundamentally, if brains learn by putting out actions and evaluating feedback it seems reasonable to expect such behavior to encompass actions that are consciously self-directed as well as those occurring without conscious awareness. The idea that by paying attention our brains notice whenever predictions are incorrect and are able to adjust their internal models seems to me to suggest a role for conscious self-direction. If humans are capable of building robots which can adjust their internal models in the light of experience, it seems reasonable to expect individual humans to be capable of using some of the principles of brain function to create better versions of themselves.

The knowledge that human brains are livewired suggests to me that it is not unduly optimistic to believe that individuals begin life with huge potential for self-directed personal development and that this potential in never entirely extinguished as they grow older.

Directing attention to achieve cognitive integrity

Self-direction implies an ability to direct one’s attention sufficiently to consider the consequences of alternative courses of action. An ability to direct one’s attention is a meta-cognitive capacity – it entails a degree of control over one’s own thought processes.  

You might be thinking that exercising control over thought processes is difficult enough for psychologically healthy people, so it must be impossible for people suffering from addictions, obsessions and delusions. However, in a Psychology Today article, Gena Gorlin, a psychologist, has pointed to evidence that people who appear to have a diminished capacity for rational deliberation in some aspects of their lives, can actually be helped by therapies which help them to exercise agency and acquire relevant knowledge.

In a scholarly contribution, published in 2019, Gena Gorlin and a co-author introduced the concept of cognitive integrity to describe “the metacognitive choice to engage in active, reality-oriented cognition”. (Eugenia I. Gorlin and Reinier Schuur, ‘Nurturing our Better Nature: a proposal for Cognitive Integrity as a Foundation for Autonomous Living’, Behavior Genetics, 2019, 49: 154-167. Independent scholars may be able to obtain access by following links on Gena Gorlin’s web site.)

Cognitive integrity is both a state of mental activity and a trait-like disposition. It stands in contrast to passive cognitive processing – being driven by unconsciously activated intention – and active pretense, or self-deception. The pretense of cognition occurs when we procrastinate and make lame excuses to ourselves to avoid doing things that we have chosen to do. Among other things, self-deception can also involve negatively distorted self-assessments, inaccurate causal attribution for life events, and false memories. Those cognitive biases are common among individuals with depression and anxiety.

Gena Gorlin posits that people who engage in repeated exercise of cognitive integrity earn self-trust. By contrast, those who engage in frequent self-deception are likely to harbor an increasing sense of insecurity about their own abilities.

It seems to me that there is a strong overlap between people who practice cognitive integrity and people who are self-authoring and self-transforming, according to definitions adopted by Robert Kegan and Lisa Laskow. A self-authoring mind is self-directed and can generate an internal belief system or ideology. A self-transforming mind can step back from and reflect on the limits of personal ideology. You can read more about that and how I see it as linked to personal integrity in Freedom, Progress, and Human Flourishing (pp 171-173). There is also relevant discussion on this blog.

Personal development as a multi-stage process

The information we have about the livewired nature of brains is suggestive of substantial potential for individual personal development throughout life. The process of personal development can be seen as a multi-stage process involving interaction between a person’s family and social environment and the degree of cognitive integrity they achieve.

In Freedom, Progress, and Human Flourishing, I make use of an analytical framework proposed by the economist, Gary Becker, to propose that the extent to which an individual flourishes at any time during her or his life, is a function of personal capital and social capital.

Personal capital includes all personal resources, natural abilities, skills acquired through education and on-the-job training, and preferences, values and habits acquired from past experiences. For example, habit formation causes previous consumption patterns to have a large impact on current preferences. Those habits can either enhance or inhibit an individual’s flourishing.

Social capital incorporates the influence of other people—family, friends, peer groups, communities. People want respect, acceptance, recognition, prestige, and so on from others and often alter their behavior to obtain it. Social capital can have a positive or negative impact on an individual’s flourishing. For example, peer pressure on a teenager could lead to sexual promiscuity, or to healthy exercise.

This framework recognizes that present choices and experiences affect personal capital in the future, which in turn affects future flourishing. It is difficult to modify the social capital of the networks to which individuals currently belong, but they may have opportunities to leave networks that damage their prospects of flourishing, and to join other networks.

I wrote:

“The journey of life is a multi-stage process. At each stage, the extent that we can flourish depends on effective use of personal capital we have developed in earlier stages, and alertness to opportunities for further investment in personal capital. Investment in personal capital can help us to forge mutually beneficial relationships with others and, if necessary, to enter more favorable social networks. As we flourish, our priorities may change, bringing about changes in preferences and behaviors. At each stage of adult life, flourishing requires values consistent with wise and well-informed self-direction.”

Is "scout mindset" a worthy objective of personal development?

 

If someone had mentioned “scout mindset” to me a week ago, I would probably have thought they were referring to mottos of the scouting movement such as “Be prepared!” and “Do a good turn every day!”. Since then, I have had the opportunity to read Julia Galef’s book, Scout Mindset, Why some people see things clearly and others don’t, which was published last year.

I think this is a remarkably good book - even though it has left me feeling somewhat more modest about the accuracy of some of my perceptions.

Scout mindset versus soldier mindset

Julia Galef defines scout mindset as ‘wanting your “map” – your perception of yourself and the world – to be as accurate as possible’. The scout aims to form a map of the strategic landscape. The scout mindset is characterized by accuracy motivated reasoning and guided by the question: Is it true?

By contrast, “soldier mindset” is aimed at fighting off threatening evidence. It is directionally motivated reasoning, evaluating ideas through the lenses of “Can I believe it?” and “Must I believe it?”

Galef suggests that soldier mindset is our default setting, and argues that in many, if not all situations we would be better off abandoning it and learning to adopt a scout mindset instead.

I am inclined to the view that intuitive thinking is our default setting, and that there are often good reasons to be reluctant to abandon intuitions and expectations that are based on patterns that have we have observed in the past. Nevertheless, it is probably fair to argue that most of us have a tendency to keep fighting conflicting evidence long after it should have persuaded us to change our minds. That is the soldier mindset. When we adopt a scout mindset, we begin to assimilate the evidence and re-assess our views sooner – perhaps by engaging in reasoning akin to Bayesian updating of probabilities.

Galef explains that there are several reasons why people tend to adopt a soldier mindset. It enables them to avoid unpleasant emotions by denial or by offering comforting narratives. It helps them to feel good about themselves by maintaining illusions. It helps them to motivate themselves by exaggerating their chances of success. It helps them to convince themselves so they can be more successful in convincing others. It enables them to choose beliefs that make them look good. It also helps them to belong to social groups of like-minded people.

The author suggests that scout mindset is more useful to us than for our ancestors. I have some reservations about that claim. Scout mindset would have been a useful attribute for our hunter and gatherer ancestors when they were searching for food. Nevertheless, she is persuasive in arguing that, by comparison with your ancestors, “your happiness isn’t nearly as dependent on your ability to accommodate yourself to whatever life, skills, and social groups you happened to be born into”.

In subsequent chapters, Galef proceeds to discuss how to develop self-awareness, thrive without illusions, change your mind, and develop a scout identity. In what follows, my focus is selective. Readers seeking a more comprehensive review should also read Jon Hersey’s article in Quillette, which persuaded me to read the book.

It seems to me that the strongest objection that people raise to having accurate perceptions of themselves is that self-delusion serves them well. The strongest objection to seeking accurate perceptions relating issues of public policy is that it is not worth attempting because the individual voter’s influence on policy outcomes is insignificant. I will look at those objections before discussing scout identity as an objective of personal development.

Does self-delusion serve us well?

A substantial amount of psychological research purports to show that people who deceive themselves are happier than realists. Galef points out that these research findings are based on measures of self-deception that lack any objective standards of reality as a basis for comparison. They use measures of self-deception that conflate positive beliefs with illusions. For example, the measurement methodology assumes that people who claim that they never get angry are deceiving themselves. Similarly, people who claim that they always know why they like things are assumed to be deceiving themselves.

It is not necessary for us to deceive ourselves about the probability of success before embarking on new ventures. Galef refers to Elon Musk as an example of an investor who has proceeded with ventures even though he has a clear-eyed view that they have a low probability of success. When asked why he has said:

“If something is important enough you should try. Even if the probable outcome is failure”.

A gamble can worth taking if the expected payoff (value of each outcome x probability of occurrence) is positive.

There can also be an issue of perspective involved in assessing probability of success. I find it helpful to think in terms of adopting a player mindset rather than a spectator mindset. On the basis of past performance, spectators might be justified in assessing that the player has low probability of success in a particular event. However, a coach who knows a great deal about the player’s capability might have good reasons to suggest to her that the spectators are under-rating her chances. Encouraging the player to adopt a mindset that makes use of her inside knowledge might induce her to take a more positive attitude toward training etc. My point is that adopting a player mindset is an exercise in realistic self-appraisal, rather than self-deception.

Julia Galef is not alone in being critical of empirical research which purports to show that holding positive illusions about oneself tends to promote happiness. As previously noted on this blog Neera Badhwar has also taken that position, and has argued strongly that realistic optimism about oneself and one’s future beats unrealistic optimism. Badhwar also notes that Abraham Maslow and Carl Rogers, leaders of the human potential movement, viewed realism as central to mental health and well-being. She notes that in Rogers' view the fully functioning individual is open to experience, distorting neither his perceptions of the world to fit his conception of himself, nor his conception of himself to fit his perceptions of the world. I find this particularly interesting in the light of Rogers’ use of Alfred Korzybski’s notion that “the map is not the territory”. Carl Rogers recognized that our maps do not serve us well if they are not realistic.

Why seek accurate maps of public policy issues?

Readers who are familiar with Chapter 6 of Freedom, Progress, and Human Flourishing will be aware of my concern that individual voters lack incentive to become well-informed about policy issues. Most voters are either apathetic about politics, or view it in the same way as they view sporting contests. They cheer for their team and jeer at their opponents.

Galef discusses Bryan Caplan’s concept of rational irrationality. In explaining what he means by rational irrationality Caplan suggests:

“In real world political settings, the price of ideological loyalty is close to zero. So we should expect people to ‘satiate’ their demand for political delusion, to believe whatever makes them feel best” (The Myth of the Rational Voter, p 18).

Galef rejects the view that voters are rationally irrational on the grounds that it implies that they are “already striking an optimal balance between scout and soldier”. She seems concerned that if she were to accept that rational irrationality is widespread, she would have to appeal to the desire of the readers of her book to be good citizens, and/ or to love truth, in urging them to adopt a scout mindset.

However, it seems to me that readers of this book who have any interest in politics are more likely to be Vulcans than Hooligans – to use the terminology of Jason Brennan (in Against Democracy, 2016). Vulcans try to avoid bias, while the Hooligans are the rabid sports fans of politics. The Hooligans are so wedded to soldier mentality that their beliefs are determined by the social groups that they identify with. The only hope of persuading these soldiers to modify political beliefs that are at variance with reality rests with the ability of scouts to persuade the generals (opinion leaders they respect) to modify their views.

Galef has little respect for those Vulcans whose reasoning resembles that of Spock in Star Trek, but has plenty of advice for people who really want to avoid bias in beliefs relating to policy issues. For example, she discusses the research of Phil Tetlock, which suggests that people who are willing to make subtle revisions of forecasts of global events in response to new information tend to make more accurate forecasts than academic experts.  

The author also has some interesting advice for people who want to reduce bias in their beliefs by exposing themselves to views outside of their echo chambers. Exposing partisans to the views of their political opponents tends to reinforce their existing views. She suggests:

“To give yourself the best chance of learning from disagreement, you should be listening to people who make it easier to be open to their arguments, not harder. People you like or respect, even if you don’t agree with them.”

Scout identity

Galef notes that identifying with a belief can wreck your ability to think clearly because you feel that you have to defend it, which motivates you to feel that you have to collect evidence in its favour. She suggests that activists are likely to be most successful if they hold their identity lightly enough to be capable of engaging with the views of opponents and making clear-eyed assessments of the best ways to achieve goals.

The author presents several arguments for seeking to adopt scout identity, but suggests that the most inspiring one is “the idea of being intellectually honorable: wanting the truth to win out, and putting that principle above your own ego”.

In reading The Scout Mindset, I was struck by parallels between the argument presented for adoption of scout mindset and the views of Robert Kegan on stages of mental development from a socialized mind, which enables people to be faithful followers and team players, to a self-authoring mind and self-transforming mind. Readers wishing to investigate further might find it helpful to read Immunity to Change, by Robert Kegan and Lisa Lahey. (I discuss the book here.) 

Conclusions

In my view Julia Galef makes a strong case for people to seek to have realistic maps - perceptions of themselves and the world that are as accurate as possible.

The author successfully challenges research findings claiming that self-deception contributes to happiness of individuals, and she provides useful advice to those seeking to make their maps more accurate.

Galef offers particularly useful advice for people seeking better mapping of public policy issues. If you want to become less biased, listen carefully to the views of opponents you respect rather than seeking exposure to opponents you do not respect.

I agree with the author that the most important reason to seek to have realistic maps is because that is intellectually honorable. Scout mindset is a worthy objective of personal development.

Who should read "Freedom, Progress, and Human Flourishing"?

 

I have dedicated the book to those who reflect on what it means to be a flourishing human.

When individuals think about their own personal development, they are reflecting on what it means to be a flourishing human.  I believe that reflection on what it means to be a flourishing human also holds the key to understanding the importance of liberty, and its role in economic development.

What is the book about?

The book explains how freedom (liberty) enables individuals to flourish in different ways without colliding, how it fosters progress and enables growth of opportunities, and how it supports personal development by enabling individuals to exercise self-direction.

The importance of self-direction is a theme of the book. The introductory chapter explains that wise and well-informed self-direction is integral to flourishing because it helps individuals to attain health and longevity, positive human relationships, psychological well-being, and an ability to live in harmony with nature.

Part I discusses natural rights and the evolution of freedom since ancient times. It explains how most people living in the liberal democracies today came to enjoy greater freedom than their ancestors.

Part II discusses progress. It explains how cultural change made economic progress possible by supporting the rule of law, liberty, and interpersonal trust, as well as the advance of knowledge, respect for innovators and tolerance of diversity. It notes that progress has led to increasingly widespread opportunities for people to meet their aspirations. It also discusses reasons for apprehension about the continuation of progress.

Part III considers how it is possible for individuals to meet the challenges of self-direction and to enhance their potential to flourish by investing in personal development. It explains that while the exercise of practical wisdom has always been integral to the flourishing of individuals, it has become commonplace for people to aspire to exercise meaningful self-direction over their lives to a greater extent than has ever been possible in the past.

The main message of the book is that people who live in Western liberal democracies should count their blessings. They have many blessings to count!

What are reviewers saying about the book?

Doug Rasmussen, a philosopher, and joint author with Douglas Den Uyl of a trilogy of books about liberty and human flourishing writes:

“Freedom, Progress, and Human Flourishing is a highly informed, but not an unduly technical, account of human flourishing and the need for a political/legal order that has the primary goal of protecting individual rights. This work is informed by not only philosophical but also by psychological and economic studies. This work provides an excellent entry point for deeper discussions of these fundamental claims.”

Readers who are seeking deeper discussions will find much to think about in the books by Rasmussen and Den Uyl: Norms of Liberty, The Perfectionist Turn, and The Realist Turn: Repositioning Liberalism.

Ron Duncan, a distinguished Australian economist with particular expertise in the economics and governance of developing countries, writes:

“With so much attention on identifying issues we should be unhappy about, Winton Bates' book is a welcome relief, given its emphasis on how much the lot of most people—particularly those in western liberal societies—has improved, why the improvements have taken place, and why they should continue. Its historical coverage of the philosophical issues underpinning the role of liberty in western progress should delight all serious thinkers.”

Ed Younkins, author of Flourishing and Happiness in A Free Society and Capitalism and Commerce writes:

“This masterful feat of integration of a wide range of literature from philosophy, economics, political science, and the social sciences will inspire scholars to bring their disciplines together to advance the argument for a free society.”

What are my qualifications to write such a book?

I am an economist. I first became professionally involved in broad issues concerning human flourishing in the early 1990s. Before then, my career focused on public policy relating to economic development, international trade, productivity growth and technological progress. Whilst retaining my professional interest in such matters, I have become increasingly interested in economic history, happiness economics, behavioral economics, self-help psychology, politics, and Aristotelian philosophy. I have written extensively about freedom and flourishing and have been blogging on this site for about 12 years.

How do I perform when interviewed about my book?

Potential interviewers who need to make such an assessment should take a look at me being interviewed by Leah Goldrick. The interview entitled “Freedom Helps us Flourish” has been published on Leah’s Common Sense Ethics channel on YouTube. The interview is also a useful source of background information about the book and its author.

Where can the book be purchased?

The book has been published by Hamilton Books and can be purchased at the Rowman and Littlefield web site: https://rowman.com/ISBN/9780761872665/Freedom-Progress-and-Human-Flourishing

It is also available from Amazon and some other booksellers.

Does evolutionary psychology shed light on the source of human intuitions?

 

I have difficulty thinking of Aristotle as a blank slate theorist. The view that evolved psychological adaptations play no role in determining human behavior seems impossible to reconcile with Aristotle’s teleological view that living entities contain in themselves the principle of their own development. It is worth remembering, however, that Aristotle saw personal development as linked to formation of good habits – he saw roles for both nature and nurture in human flourishing. In order to make sense of the passage quoted above I need to allow myself to imagine a blank writing tablet that has functional specialization allowing information relevant to the flourishing of our pre-historic ancestors to be most readily written upon it. (Incidentally, the quote is from On the Soul, Book III, Part 4.)

Evolutionary psychology has promoted the view that evolved psychological adaptations play a role in determining human behavior. To consider the light it sheds on the source of human intuitions I will begin with Steven Pinker’s list of the cognitive intuitions (also referred to as modules, systems, stances, faculties, mental organs, multiple intelligences, and reasoning engines), and then move on to Jonathan Haidt’s list of ethical intuitions. I will then consider whether attacks on evolutionary psychology should cause us to be wary of the evolutionary reasoning associated with such lists.

Pinker suggests that we are equipped with a range of different cognitive intuitions that evolved through psychological adaptations to keep our ancestors in touch with reality. These intuitions emerge early in life, and are present in every normal person. His list includes a basic intuitive grasp of physics, biology, engineering, psychology, and economic exchange. It includes a spatial sense, and senses of number and probability. It also includes language, and a mental data base and logic that are used to represent ideas and infer new ideas from old ones. These intuitions are suitable for the lifestyles of small groups of illiterate people living several thousands of years ago. They do not give people a spontaneous intuitive understanding of modern science, technology, or economics. (Steven Pinker, The Blank Slate, 2002, 219-21)

Haidt argues that moral intuitions evolved to meet various adaptive challenges faced by our ancestors. He suggests that moral intuitions relating to care and harm evolved to protect children; intuitions relating to fairness and cheating evolved to reap benefits of cooperation; intuitions relating to loyalty and betrayal evolved to protect groups from challenges; intuitions relating to authority and subversion evolved to obtain benefits from hierarchies; and intuitions about sanctity and degradation evolved to avoid contamination and disease. (Jonathan Haidt, The Righteous Mind, 2012, 123-127)

The views of Pinker and Haidt seem to me to be plausible, but can this kind of reasoning withstand the criticism that evolutionary psychology consists of “just so” stories?  

In his book, Rethinking Evolutionary Psychology, Andrew Goldfinch, a philosopher, tells readers that critics view evolutionary psychology explanations “as shockingly naked in historic and scientific detail”. Massive modularity has been a particular focus of criticism. The strongest form of massive modularity claims that there are no systems or mechanisms that are not dedicated to particular problems.

I came to Goldfinch’s book with the idea that the concept of brain plasticity was opposed to modularity. I had thought that evidence that brains “rewire” themselves in response to experience as people transition from infancy to adulthood would tend to count against modularity. However, many cognitive psychologists stress that when they talk about modules what they have in mind is functional specialization which is consistent with overlap between processing areas of the brain. Plasticity enables brains to develop so that individuals normally have intuitions that are common among adult humans.

However, Goldfinch also makes it clear that the existence of innate knowledge does not require massive modularity. It is possible for domain-specific knowledge to be generated by domain-general processing. Both domain-specific and domain-general mechanisms are compatible with evolutionary theory. I think it follows that the issue of whether the lists of intuitions compiled by Pinker and Haidt are evolutionary adaptations does not depend on the validity of the theory of massive modularity.

The main point that Goldfinch makes is that leading evolutionary psychologists have brought their research program into disrepute by packaging it as a paradigm shift. The research program became identified with claims of a strong form of massive modularity as leading proponents argued that evolutionary adaptation implies the existence of strong massive modularity. Leading proponents used the concept of strong massive modularity to challenge conventional social science based on the foundation of domain-general knowledge and processes that are exclusively social. This prompted excessively critical responses that sought to discredit the entire research program as “just so” stories.

Goldfinch argues that strong massive modularity is not integral to evolutionary psychology. He suggests that evolutionary psychology should be viewed as an exploratory research program aimed at generating and testing hypotheses about psychological mechanisms. Viewed in that light, evolutionary psychology explores whether psychological traits that are observed across cultures could be adaptations, and has potential to guide researchers into identifying new behavioral patterns and mechanisms.

Goldfinch summarizes his view as follows:

“Initial evolutionary psychology hypotheses aim, or should aim, not for the last evolutionary word on a given phenomenon, but the first. They are in constant adjustment—both with the research programme’s own findings and findings from adjacent research programmes and disciplines. If this is done, this should generate sophisticated hypotheses, as well as generate progressive increments to our understanding of psychological and social phenomena.” (200)

I can see the wisdom in Goldfinch’s suggestion that evolutionary psychologists should not be aiming to have the last word. Should any scientist ever be aiming to have the last word? However, I think it is inevitable that a good number of the hypotheses advanced by evolutionary psychologists will challenge beliefs that human behavior is wholly attributable to simple mechanisms of learning and can be modified readily by changing social arrangements.  

Even if the views about human intuitions put forward by evolutionary psychologists only have the status of plausible speculations, they can still help us to comprehend aspects of the world we live in. For example, Pinker’s views provide a provisional understanding of why people tend to perceive the world they live in much the same way as their ancestors who knew nothing about the processes that modern physics describes. Haidt’s views provide a provisional understanding of why people hold ethical intuitions that cannot be readily explained in terms of current social circumstances. The paucity of historic detail supporting such speculations should not cause them to be dismissed unless more plausible explanations are offered. Those seeking truth should find plausible speculations more satisfying than implausible speculations and mysteries.    

How is behavioral economics relevant to human flourishing?

The practitioners of behavioral economics have tended to direct their research findings mainly at “choice architects”, including paternalistic governments. For example, in their book, Nudge, Richard Thaler and Cass Sunstein adopt the term “libertarian paternalism” to propose:

“Choice architects can preserve freedom of choice while also nudging people in directions that will improve their lives”.

An example might help to clarify what a nudge involves. If the government were to invest a certain proportion of your income in a superannuation fund on your behalf this would amount to a nudge, rather than a push or a shove, if you were allowed to withdraw the funds at any time to use as you wished. Because of a tendency for people to avoid choices, or to choose default options, such an arrangement would be likely to result in more investment in superannuation than one that relied solely on tax incentives. It would do this without the interference in personal choice that is involved in compulsory superannuation, such as exists in Australia. (That example is taken from my review of Nudge.)

However, if you view human flourishing as an essentially self-directed activity, as I do, you may be sceptical about claims that such nudging can improve your life. Even if the people doing the nudging have your interests at heart, their perception of what will improve your life will not necessarily accord with your own preferences.

In the example provided above, additional transactions costs may be imposed on the person being nudged. For example, investment in superannuation might not be the best option for a young person wanting to save for a deposit on a house. Over the longer term, the value of an investment in a superannuation fund could be expected to rise to a greater extent than cash in the bank, but short term fluctuations in equity prices make superannuation a less suitable vehicle for shorter term saving. Withdrawing funds for a house deposit could result in capital losses being incurred.

Robert Sugden suggests that “something is clearly wrong if economists think that their response to the discovery of mistakes in individual decision-making must take the form of a recommendation about public policy” (The Community of Advantage, p 44). If you want to help individuals to make better decisions it makes more sense to address the information to those individuals rather than to address it to autocrats.  (I have previously discussed The Community of Advantage here, here and here.)

Sugden makes the point that nudgees (people who are nudged) do not always explain their failure to follow expert advice in terms of self-control problems. For example, an obese person who fails to follow expert advice about choosing fruit rather than cake, could explain his choice in a range of different ways that do not involve a self-control problem. If he sees nothing wrong with his choices, he has no reason to want to be nudged by having the fruit placed in a more prominent position in the cafeteria relative to the cake (p 47).

However, if the obese person acknowledges that he has a self-control problem, research findings about the influence of placement of products on consumer purchases might help him to modify his behaviour. His trusted advisers might be able to suggest how he could nudge himself to make better choices. By coincidence, earlier today, I heard a news item indicating that there is a supermarket chain in Australia that refrains from placing confectionary near checkouts. That information could be relevant to a person with an acknowledged self-control problem, who was wanting to avoid impulse purchases of confectionary.

The fact that supermarkets often place confectionary near checkouts illustrates that choice architects may not always have paternalistic motives. It should not be assumed, however, that their motives are exploitive. Supermarkets want loyal customers, so it is not likely to be in their interests to have shoppers end up feeling that they have been manipulated to make unhealthy choices and/or to spend more money than they wanted to spend. It is possible that the placement of the confectionary helps give most shoppers good feelings about their shopping experience. The nudge that one person views as manipulative may be viewed by others as benign, or even as providing a helpful reminder.

As a rule, it is good to be aware how you are being nudged in the choices you make. It is necessary to be aware that you are being nudged, as the first step in making a conscious choice to accept or reject the suggestion involved. Behavioural economics can make a useful contribution in helping to make us aware of how nudges may affect the choices we make.

Sugden suggests that behavioural economists who discover possible mistakes in individual decision-making are in an analogous situation to epidemiologists who discover an apparent causal relationship between some activity and the prevalence of an illness. The epidemiological findings are made available to the public in various ways and begin to influence behaviour prior to any public policy intervention being contemplated (p 43). 

Similarly, happiness researchers who discover that average life satisfaction of various groups is affected by factors such as leisure, or commute times, are providing information that individuals may wish to consider in the choices they make.  Individuals are likely to be affected differently, but rarely so differently that information about others is irrelevant.

Sugden acknowledges that normative economics has almost always been directed toward public decision-makers rather than private individuals, but suggests that “since economists often characterize their discipline as the science of rational choice one might expect them to recognize the potential value of helping individuals to make better decisions in their private lives” (p 43). He notes that Philip Wicksteed, one of the founders of neoclassical economics, presented economics as a study of the “general laws of the administration of resources” and insisted that these laws apply “from end to end of life”. He gave practical advice on how to avoid common mistakes in decision-making. The passage quoted above reflects the role he saw for economists in helping people to make better choices.

Sugden’s view that there is a role for economists in helping individuals to make better choices seems somewhat at variance with the view of James Buchanan. In his article “What should economists do?”, published in 1964, Buchanan argued that the theory of choice should be removed from “its position of eminence in the economist’s thought processes”. He suggested that economists should concentrate their attention on human behaviour in market relationships and other voluntaristic exchange processes, and upon the various institutional arrangements that can arise as a result of this form of activity.

I maintain the view, as previously expressed, that Buchanan is correct in identifying the heartland of economics to be concerned with voluntaristic exchange processes, but that does not rule out the potential for economists to make useful contributions in helping individuals to make better personal choices. It is in the latter context that behavioural economics is most relevant to human flourishing.

Which are the countries in which people have the best opportunities for psychological well-being?

This might seem like an odd question, so I will begin by explaining why I think it is worth considering.

Psychological well-being was identified in a recent post on this blog as one of five basic goods that a flourishing human would be expected to have. The post listed a range of aspects involved in psychological well-being: emotional stability, positive emotion, satisfaction with material living standards, engagement in doing things for their own sake and learning new things, perception of life as meaningful, a sense of accomplishment, optimism, resilience, vitality, integrity, and self-respect.

It seems reasonable to expect that opportunities for individuals to experience some of those aspects of psychological well-being might be greater in some countries than in others.

In compiling my list of aspects of psychological well-being, my starting point was the definition of psychological flourishing adopted by Felicia Huppert and Timothy So in their article ‘Flourishing Across Europe’ (published in Soc.Indic.Res. in 2013). These authors view psychological flourishing as lying at the opposite end of a spectrum to depression and anxiety. They identified 10 symptoms of flourishing (competence, emotional stability, engagement, meaning, optimism, positive emotion, positive relationships, resilience, self-esteem, and vitality) as the opposites of internationally agreed criteria for depression and anxiety (DSM and ICD). The study has previously been discussed on this blog.

My main modification to Huppert and So’s list is the addition of satisfaction with material living standards. In my view, people who feel miserable because they are dissatisfied with their material living standards are deficient in psychological well-being, even though they may not be suffering from the symptoms of depression or anxiety.

Despite my desire to modify the measure of psychological flourishing constructed by Huppert and So, it strikes me as providing a good basis for international comparison of psychological well-being. Unfortunately, this measure is only available for European countries, and for one year, 2006. That leads me to consider whether life satisfaction is a satisfactory alternative measure.

Is life satisfaction good enough?

The chart shown above suggests that, at a national level at least, the percentage of people who are satisfied “with how life has turned out so far” (ratings of 9 or 10 on a scale of 0 to 10) is a good predictor of psychological flourishing. In a simple linear regression, the percentage with high life satisfaction explains 83% of the inter-country variation in the percentage who are flourishing. (The chart was constructed using life satisfaction data from the 2006 European Social Survey used by Huppert and So to construct their psychological flourishing indicator.)

The idea that life satisfaction could a good enough measure of psychological flourishing might appear to be at variance with the findings of Huppert and So.  As discussed in an earlier post, Huppert and So found that only 46.0% of people who met the criterion for flourishing had high life satisfaction, and only 38.7% of people who had high life satisfaction met the criterion for flourishing.

 

However, the appropriateness of life satisfaction as an indicator of psychological flourishing depends on the purpose for which the indicator is to be used. If you want to know about an individual’s psychological well-being, it is hardly surprising that a single question about life satisfaction has been found to be a poor indicator. If your focus is on average psychological well-being at a national level, life satisfaction seems to be a good enough indicator because much of the measurement error at an individual level washes out in calculating national averages.

The countries with highest average life satisfaction

Average life satisfaction data from the Gallup World Poll is published annually in the World Happiness Report. This data set covers many countries and measures life satisfaction according to the Cantril ladder scale, with a rating of 10 being given to the best possible life and a rating of zero is given to the worst possible life.

In the 2018 survey, average life satisfaction ratings were greater than 7 in 15 countries: Finland, Denmark, Switzerland, Netherlands, Norway, Austria, Sweden, New Zealand, Luxembourg, United Kingdom, Australia, Canada, Costa Rica, Germany and Czech Republic. Average ratings tend to be fairly stable from year to year, but a decade earlier, Ireland, Spain, U.S, Israel, Belgium and France had average ratings above 7, and U.K, Costa Rica and Germany had ratings below 7.

Regression analysis undertaken by John Helliwell et. al. show that almost three-quarters of the variation in national annual average life satisfaction scores among countries can be explained by six variables: GDP per capita, networks of social support, healthy life expectancy, freedom to make life choices, generosity, and freedom from corruption. That list of variables has a strong overlap with determinants of other basic goods in my list of the five basic goods that a flourishing human could be expected to have. (See other posts in this series, here, here and here.) Apart from GDP per capita and healthy life expectancy, however, the data used in the analysis of Helliwell et al are based on perceptions of survey participants rather than objective measurement. (The analysis is a pooled regression using 1704 national observations from the years 2005 to 2018.)

Since my focus is on identifying countries where a person chosen at random would have the best opportunities, the median life satisfaction for each country would be a better criterion than the mean. Unfortunately, I don’t have access to such data at a national level. Estimates of median life satisfaction for broad regions (based on data here) suggest that median life satisfaction is typically lower than the mean. The difference between mean and median tends to be small for countries with relatively high life satisfaction: Western Europe (6.6 for mean cf. 6.4 for median) and North America and ANZ (7.1 cf. 6.9). The difference more substantial in some other parts of the world e.g. South East Asia (5.4 cf. 4.8).

Avoiding and reducing misery

In considering which countries offer the best opportunities for psychological well-being, countries with high average life satisfaction would be less attractive to risk averse people (most humans) if a relatively high proportion of the population of those countries nevertheless lived in misery. However, available evidence suggests that factors that lead to high life satisfaction also tend to reduce misery. For example, it is apparent from the graph below that the regions of the world with highest average life satisfaction tend also to have the lowest percentages with low life satisfaction.

A study by Andrew Clark et al for the World Happiness Report 2017 used data for the U.S., Australia, Britain and Indonesia to examine how much misery would be reduced if it was possible to eliminate one or more key determinants. The factors considered were poverty, low education, unemployment, living alone, physical illness, and depression and anxiety disorders. The authors found that the most powerful impact would come from the elimination of depression and anxiety disorders.

Conclusions

Life satisfaction is not a particularly good indicator of individual psychological well-being, but it seems to be a good enough indicator to use in international comparisons.

Countries with the highest average life satisfaction are characterised by relatively high income levels and life expectancy, accompanied by perceptions of strong social support, freedom and low corruption. The percentage of the population who are dissatisfied with life tends to be relatively low in such countries.

Where did Adam Smith's 'system of natural liberty' come from?

In Wealth of Nations, Adam Smith (1723 -1790) famously wrote that when all systems of government

preferment or restraint for particular “species of industry” are removed, “the obvious and simple system of natural liberty establishes itself of its own accord”.

He went on to explain what this system of natural liberty entails:

‘Every man, as long as he does not violate the laws of justice, is left perfectly free to pursue his own interest in his own way, and to bring forth both his industry and capital into competition with those of any other man, or order of men. The sovereign is completely discharged from a duty [for which] no human wisdom or knowledge could ever be sufficient; the duty of superintending the industry of private people, and of directing it towards the employments most suitable to the interest of the society’. (WN, IV.ix.51).

Smith’s use of the value-laden term, ‘natural liberty’, seems to have been intended to convey that it is good for everyone to be free to pursue their individual interests, even in the absence of more tangible mutual benefits. That ethical connotation is even stronger in other passages in Wealth of Nations (WN) where Smith refers to violations of natural liberty as unjust.

Jerry Muller suggests that “the display” of the ‘system of natural liberty’ contributes to the great persuasive power of the WN, but might “lead many readers to overlook the complexity of Smith’s conception of the moral life and to conclude that liberty, in itself, was always a good thing” (The Mind and the Market, 2002, p 83).

In my view, it is likely that Smith would have been pleased to have readers accept his vision of natural liberty and limited government as unambiguously good. I think he would have wanted people to recognise that it was an unjust infringement of natural liberty for the powers of government to be used to assist some economic groups at the expense of others.

Nevertheless, as Nicholas Phillipson highlights in his biography, Smith’s political prescriptions for market liberalisation were pragmatic. He recognised the need for a gradual approach to the removal of obstructions to avoid provoking dangerous opposition from opposing interests (Adam Smith, An enlightened life, 2010, p 230-31).

The authors of the introduction to the 1976 edition of The Theory of Moral Sentiments suggest that Smith’s reference to “the obvious and simple system of natural liberty” in WN reflects the influence on him of the Stoic concept of natural harmony. (The editors D. D. Raphael and A. L. Macfie acknowledge help from Walter Eckstein in writing the introduction.)

Smith’s reference to natural liberty could also reflect the influence of more recent philosophers, including Francis Hutcheson (1694 – 1746), who taught Smith moral philosophy at Glasgow university. Hutcheson’s philosophical interests included the nature of virtue, the meaning of sociability and natural rights. His teaching and writings were deeply respected in radical Whig circles in Britain and the American colonies.

Smith’s ideal of everyone being free to pursue their own interests in their own way seems to echo Hutcheson’s explanation of the right to natural liberty in terms of pursuit of happiness:

“As nature has implanted in each man a desire of his own happiness, and many tender affections toward others in some nearer relations of life, and granted to each one some understanding and active powers, with a natural impulse to exercise them for the purposes of these natural affections; 'tis plain each one has a natural right to exert his powers, according to his own judgment and inclination, for these purposes, in all such industry, labour, or amusements, as are not hurtful to others in their persons or goods, while no more public interest necessarily requires his labours, or requires that his actions should be under the direction of others. This right we call natural liberty.”

Smith and his followers would want to redraft that a little to define the meaning of what is hurtful to others in terms of fair play, or respect for their rights. There is also the question of how to define the “public interest” that apparently has priority over private interests.

 Hutchison goes on to assert:

“Every man has a sense of this right, and a sense of the evil of cruelty in interrupting this joyful liberty of others, without necessity for some more general good. Those who judge well about their own innocent interests will use their liberty virtuously and honourably; such as have less wisdom will employ it in meaner pursuits, and perhaps in what may be justly censured as vicious.”

Smith doubted that everyone is born with such moral instincts. He argued that individuals gained the perspective of an impartial spectator to judge their own actions via a socialisation process.

Hutcheson argues that people resent infringements of liberty:

“the sense of natural liberty is so strong, and the loss of it so deeply resented by human nature, that it would generally create more misery to deprive men of it because of their imprudence, than what is to be feared from their imprudent use of it."

Hutcheson doesn’t see any problem with persuasion:

“Let men instruct, teach, and convince their fellows as far as they can about the proper use of their natural powers, or persuade them to submit voluntarily to some wise plans of civil power where their important interests shall be secured.”

Francis Hutcheson sums up:

“This right of natural liberty is not only suggested by the selfish parts of our constitution, but by many generous affections, and by our moral sense, which represents our own voluntary actions as the grand dignity and perfection of our nature.”

(The quoted passages by Francis Hutcheson are from A System of Moral Philosophy, published posthumously in 1755, pp 293-5.)

Can subjectivism and objectivism be reconciled?

Readers who don’t recognise the faces depicted in my amateurish artwork might be thinking that the question is absurd because opposites can never be reconciled. That is a feature of the real world. However, subjectivism and objectivism are labels that have been attached to different schools of thought. We need to look at what lies behind the labels to assess whether the schools of thought can be reconciled.

I have previously struggled with related issues when considering whether human well-being is subjective or objective. I will return to that question later in this post.

Edward Younkins has little difficulty in reconciling subjectivism and objectivism in his excellent book, Flourishing and Happiness in a Free Society, 2011. The book is subtitled, Towards a synthesis of Aristotelianism, Austrian Economics and Ayn Rand’s Objectivism. The subtitle accurately summarises what the book is about. This is a scholarly work that should be read by anyone who has reasons to be interested in whether such a synthesis is possible. Readers of this blog will have observed that the approach to freedom and flourishing adopted here is eclectic, but strongly influenced by Neo-Aristotelian classical liberal philosophy and Hayekian economics. Ed’s reconciliation of objectivism and subjectivism goes part of the way in helping me to think about the coherence of my own views.

Reconciling Mises and Rand

The Austrian economist to whom Ed devotes most attention is Ludwig von Mises. Mises observed that all human action involves choices that are made subjectively by individuals having regard to their internal purposes, ends or goals. Valuation reflects the acting person’s internal scale of preferences. Mises held that economists should study the implications of individual human actions without regard to their motives or causes, which are the objects of study for psychologists.

Ayn Rand argued that the minds of the individual humans are competent to achieve objectively valid knowledge of the real world. The senses, aided by reason in accordance with the rules of logic, enable us to obtain objectively valid knowledge of reality. When a correct cognitive process has been followed, it can be said that the output of that process is objective. It is up to individuals to discover what will further their own lives and what will harm them. Values reflect facts as evaluated by persons with respect to the goal of living. The objectivity of value derives from the fact that some actions tend to promote human life and others detract from it.

Ed Younkins points out that the claim of Miserian economists that values are subjective is compatible with Rand’s claim that values are objective because “they exist at different levels or spheres of analysis”:

“The value-freedom (or value-neutrality) and value subjectivity of the Austrians have a different function or purpose than does Objectivism’s emphasis of objective values. On the one hand, the Austrian emphasis is on the value-neutrality of the economist as a scientific observer of a person acting to attain his ‘subjective’ (i.e. personally-estimated) values. On the other hand, the philosophy of Objectivism is concerned with values for an acting individual moral agent himself”.

Ed provides a more complete explanation in his book, but the quoted passage is a good summary.

Did Hayek claim that morals are not rationally justifiable?

Ed’s reconciliation of Objectivism and the subjectivism of Austrian economists doesn’t get me off the hook entirely regarding the compatibility of Hayekian and neo-Aristotelian philosophies. A decade ago, after re-reading Rand’s warnings (via John Galt in Atlas Shrugged) about becoming “an abject zombie who serves a purpose he does not know for reasons he is not to question”, I re-considered my support for Hayek’s view that there is merit in observing long-standing norms of behaviour that serve purposes beyond our understanding.  My conclusion was that both views deserve consideration. Hayek was correct to emphasise that societal norms may deserve respect even if we don’t fully understand their purpose, because they evolved through an evolutionary process in which groups that adhered to superior rules were most successful. Rand was correct to emphasise that the purpose served by rules protecting lives, liberty and property are usually capable of being understood.

There are some passages in Hayek’s final book, The Fatal Conceit, that are incompatible with neo-Aristotelian philosophy (and my own views) but it seems likely that those passages were written by W.W Bartley, the book’s editor, rather than by Hayek, whose health was deteriorating at the time. For example: “Moreover, while it is true that traditional morals, etc. are not rationally justifiable, this is also true of any possible moral code …”. Bruce Caldwell suggests that the assertion that our morals are not rationally justifiable is “a position that clearly derives from Bartley” (Hayek’s Challenge, p 317). Here are another sentence for which I hope Hayek was not responsible:

“There is no reason to suppose that the selection by evolution of such habitual practices as enabled men to nourish larger numbers had much if anything to do with the production of happiness, let alone that it was guided by the striving after it” (The Fatal Conceit, p 69).

I think that statement is false. Without downplaying the importance of survival as a motive, a realist would acknowledge that until recently human reproduction has been largely an outcome of the actions of humans striving for happiness via the habitual practice of sexual gratification. Moralists have long argued that people can’t find happiness by seeking pleasure, but that doesn’t seem to have stopped many from striving to do just that. Furthermore, the literature of the distant past, as well as more recent times, suggests that those who were most successful in passing on their genes would generally have been living in societies providing relatively good opportunities for individual human flourishing, and they would generally have been flourishing individuals enjoying good health and relative prosperity. It also seems likely that persons with happy dispositions have generally been more likely to form lasting bonds and to care for their offspring.

The objective nature of human flourishing and happiness

Ed Younkins clearly views human flourishing as an objective state of life:

“Flourishing is a successful state of life, and happiness is a positive state of consciousness that flows from, or accompanies, a flourishing life. The legitimate function of every human person is to live capably, excellently and happily. This involves an ethic of aspiration toward one’s objective well-being that is actively attained and maintained”.

Ed introduces the concept of metalevel happiness to distinguish “enduring and justified contentment with one’s life as a whole” from transitory feelings. His description of metalevel happiness seems to have firm roots in antiquity:

“Metalevel happiness requires a proper perspective that comes from the serenity or peace of mind that one gets from knowing that: (1) one is free to rationally choose among alternatives; (2) a person’s potential for happiness is oriented in some particular way and with some particular nature which is not a matter of choice; and (3) nothing external can harm the core of one’s self. Serenity requires wisdom, a sense of proportion, and the ability to deal with pain and emotions in a balanced and rational manner. Happiness means being serene in the face of the unchangeable, courageous before the changeable, and wise enough to determine which is which”.

It seems appropriate to end this post here, leaving you to ponder how best to follow Edward Younkins’ good advice about cultivating the serenity required to be objective about subjective feelings.

Isn't it good to be able to get what you want by helping others to get what they want?

When I was at university studying neoclassical welfare economics - about half a century ago - the standard discussion of the benefits and limitations of free markets began with a demonstration that, under certain assumptions, individuals with stable and internally consistent preferences could maximize their utility through voluntary transactions. As I write, I have a picture in my mind of neat sets of indifference curves in an Edgeworth Box, rather than the gains from trade diagram shown above.

Of course, in the 1960s and 70s a great deal of attention was given to market failure stemming from violation of competitive market assumptions and the existence of externalities. Since then, research by behavioural economists has provided evidence that individuals’ preferences tend to be context-dependent, rather than stable and internally consistent. For example, as we all know, what we choose to buy may be influenced by the placement of items on supermarket shelves.

Just as evidence of market failure led many economists to advocate remedial government interventions, evidence that individuals’ preferences tend to be context-dependent has been used by some behavioural economists to argue for paternalistic interventions to nudge people to make better choices. Wise economists urge that consideration should also be given to government failure - the tendency for government intervention to make matters worse even when politicians intend to produce better outcomes.

Robert Sugden has shone light through the smog caused by the standard neoclassical assumptions about individual preferences in his recently published book, The Community of Advantage. Sugden dispenses with assumptions about individual preferences by substituting the principle of individual opportunity – the idea that individuals will choose to have more opportunities rather than less.

Sugden’s book has been praised by some eminent scholars working at the interface between economics, psychology and ethics. It is pleasing that Cass Sunstein, whose advocacy of paternalistic nudges is challenged in the book, describes it as “one of the very few most important explorations of liberty in the last half-century.

Sugden makes the powerful point that there is no basis for behavioural economists to interpret contraventions of the standard neoclassical assumptions as necessarily attributable to cognitive error or self-control problems. There is no known psychological foundation for human decision-making to be modelled as “a neoclassically rational inner agent, trapped inside and constrained by an outer psychological shell”.

Nevertheless, humans obviously make cognitive errors and experience self-control problems. Should economists wash their hands of those problems and leave them for psychologists to deal with? Sugden suggests that economists may be able to help by adopting a contractarian approach – addressing their recommendations to individuals - usually by showing them how they can coordinate their behaviour to achieve mutual benefit - rather than addressing recommendations to paternalistic governments. It is consistent with a contractarian approach for economists to point out the mistakes that individuals are liable to make and to suggest types of choice architecture (e.g. nudges) that they could use, if they wanted, to avoid making those mistakes.

One of the highlights of the book is the perception it offers of the workings of “the invisible hand” of the market. The invisible hand is sometimes portrayed as something that has to be mysterious since it is able to convert self-interest into community benefits. Sugden suggests that the invisible hand is far from mysterious when perceived in terms of the activities of profit-seeking traders looking for arbitrage opportunities. If some individuals are willing to sell something at a lower price than other individuals are willing to pay to buy it, traders can take advantage of the profit opportunities of that situation. From the perspective of the buyers and sellers the transaction helps realize an opportunity for mutual benefit, whether traders are involved or not.

As I see it, from an individual’s perspective the market provides expanded opportunities along the lines suggested in the gains from trade diagram shown above. A person who subsists without trading with others has little leisure time left after eking out a living. By participating in trade - earning a market income in this example - her consumption possibilities are expanded. She is able to get more of what she wants – more leisure and/or more other goods - by helping others to get what they want.

Opportunities for mutual benefit are not limited to market exchange. Mutual benefit is possible in many different types of cooperative interaction. Sugden provides an insightful analysis of team reasoning, contrasting a contractarian approach in which individual team members seek to achieve mutual benefit with the alternative of perceiving the team as a single entity and seeking to maximize the overall good of the team, as judged from some neutral viewpoint.

The author’s analysis of adherence to voluntary practices is also insightful. He notes that individuals realize mutual benefits directly by conforming to voluntary practices, e.g. tipping conventions, because regularities of behaviour provide salient benchmarks for expectations about one another in specific interactions. By conforming to the practice, they also sustain the expectations upon which it depends and help to maintain it as an institution.

In my view, the most important contribution of the book is its discussion of the ethics of intending mutual benefit. A long-standing and recurring theme of criticism of market exchange is that it involves extrinsic motivations that are not virtuous. That line of thinking implies, implausibly, that the intrinsic satisfaction that I obtain from blogging might evaporate if I were to obtain monetary rewards for my efforts. Sugden observes that when people participate in markets they can act with the intention of achieving mutual benefit, rather than personal benefit. He urges readers to adopt the following principle of mutual benefit:

“When participating with others in a voluntary interaction, and for as long as others’ behaviour in that interaction is consistent with this very principle, behave in such a way that the other participants are able to satisfy normal expectations about the consequences of the interaction for them."

The author explains that one of the merits of the principle of mutual benefit is that what it requires of us individually is independent of the motivations of the people with whom we interact. It is in our interests to seek mutual benefit in interactions with as many other people as possible. The principle never requires us to make judgements about another person’s intentions.

The Community of Advantage is the best book I have read about the economics of human flourishing. This brief review has provided only a glimpse of what it is about. Hopefully, it has whetted your appetite to read the book.

The book has raised several issues that I hope to be able to explore further on this blog:

• Is the principle of mutual benefit consistent with the primacy of personal responsibility as discussed by Douglas Den Uyl and Douglas Rasmussen in The Perfectionist Turn?
• When is it possible for economists who are engaged in provision of public policy advice to adopt a contractarian approach?
• Does the principle of mutual benefit mesh well with the views of Elinor Ostrom on management of common property resources, the views of Vincent Ostrom on politics, and the views of Max Borders about the prospects of a Social Singularity?
