Edge: Getting at the Neuroanthropology of Morality

Edge has just posted a new seminar, The New Science of Morality. You get lots of access to interviews, links to papers, videos, exchange of views, reactions from the press, and more. Quite stimulating.

What proved interesting to me is the inherent duality in the discussion. There is a marked division between the assumed basis for this research and what many of the main researchers are actually saying. The assumed basis is in evolution and functional biology:

A realistic biology of the mind, advances in evolutionary biology, physics, information technology, genetics, neurobiology, psychology, engineering, the chemistry of materials… For the first time, we have the tools and the will to undertake the scientific study of human nature… Using babies, psychopaths, chimpanzees, fMRI scanners, web surveys, agent-based modeling, and ultimatum games, moral psychology has become a major convergence zone for research in the behavioral sciences.

But the researchers themselves often sound a lot more like neuroanthropologists, taking into account culture, relying on cross-cultural research, thinking about the dynamics of development and the interaction of nature and nurture. There’s no ethnography yet, which would really help in getting at how people and institutions think and act morally in reality. Still, the researchers’ work shows that many of these people are not in the “morality as a naturalistic brain module that simply acts on the world” camp.

Here are some examples:

Jonathan Haidt: “Morality is a social construction, but it is constructed out of evolved raw materials provided by five (or more) innate “psychological” foundations… Each culture’s morality is unique, but an aspect shared by all five-foundation moralities is that they do not regard society as a social contract created for the benefit of individuals. Rather, they see society in more organic terms, as an entity that is of value in and of itself, and they think the building blocks of society are not individuals but rather groups and institutions.”

Sam Harris: “I propose that answers to questions of human value can be visualized on a “moral landscape” — a space of real and potential outcomes whose peaks correspond to states of the greatest possible wellbeing and whose valleys represent the deepest depths of suffering. Different ways of thinking and behaving — different cultural practices, ethical codes, modes of government, etc. — translate into movements across this landscape. Such changes can be analyzed objectively on many levels — ranging from biochemistry to economics — but they have their crucial realization as states and capacities of the human brain.”

Roy Baumeister: “The human being was designed by nature for culture: That is, the distinctively human traits are those that enable us to participate in this new kind of social life, namely culture. Culture is humankind’s biological strategy. To understand human traits, therefore, it is useful to ask how each trait would have been selected for as a way of helping an individual flourish in this new kind of social environment.”

David Pizzaro: One of my primary interests is in how people arrive at judgments about moral responsibility. Most people seem to have intuitions about what sorts of things matter when determining whether a person deserves blame (or praise) for any given act. In another ongoing set of studies, we have demonstrated that moral reasoning can be influenced by motivations that may have nothing to do with moral concerns… I am particularly interested in specific emotions (anger, disgust, fear, etc.), and on “visceral” affective states (e.g., thirst, hunger, sexual arousal) and their impact on how we process information, how we remember events, and how these emotions impact our moral judgments.”

Elizabeth Phelps: “My primary focus has been to understand how human learning and memory are changed by emotion and to investigate the neural systems mediating their interactions. I have approached this topic from a number of different perspectives, with an aim of achieving a more global understanding of the complex relations between emotion and memory. As much as possible, I have tried to let the questions drive the research, not the techniques or traditional definitions of research areas… It is my belief that having focused questions and a broad approach to answering these questions has enhanced the overall quality of my research program and the cross-disciplinary relevance and appeal of my work.”

Joshua Knobe: “Over the past few years, a series of recent experimental studies have reexamined the ways in which people answer seemingly ordinary questions about human behavior. Did this person act intentionally? What did her actions cause? Did she make people happy or unhappy? It had long been assumed that people’s answers to these questions somehow preceded all moral thinking, but the latest research has been moving in a radically different direction. It is beginning to appear that people’s whole way of making sense of the world might be suffused with moral judgment, so that people’s moral beliefs can actually transform their most basic understanding of what is happening in a situation.”

To be sure, there were researchers at the Edge seminar who are fully in the evolution/innatist camp. But nonetheless, the younger researchers seem to embrace a wider and more natural approach to studying morality. And by natural I mean understanding that we are biological and cultural beings, individual and social, with the interaction between the developing person and a rich social and material environment central to how we understand our own nature.

I would encourage more serious thinking about culture, and not just the brain and psychology. Take Knobe’s statements, about “people’s whole way of makign sense of the world might be suffused with moral judgment.” That’s a statement familiar to most cultural anthropologists. The question becomes, How? It’s not as simple as saying culture imprints it on people, not at all. Pizarro’s work on disgust and visceral experiences points to embodiment and complex interactions to understanding how moral thinking gets developed inside a person.

Baumeister indicates that we are actually cultural animals, not moral ones, and that we have mechanisms designed to interact with our social-cultural milieu. But what sorts of mechanisms? And how do complex interactions among groups of people and environments create the sort of social construction of morality that Jonathan Haidt advocates (construction albeit with biological and psychological components!)? These sorts of questions need to also be part of the new science of morality.

The moral consequences of this sort of research is also important. It is something I critiqued a couple years back in the post Steven Pinker and the Moral Instinct, writing:

To help you make a final decision [about what he is selling], a linguist like Pinker will surely appreciate a little content analysis of his New York Times essay, “The Moral Instinct.” The word “science” appears ten times in the article, often in close association with “moral” or “morality.” How about Bill Gates helping out? “Help” appears six times, four of those times about how selfish genes can get ahead through reciprocal altruism. And justice? You guessed it. Zero, zilch, nada.

Also, I can’t resist this final quote from Robert Trivers, posted way, way at the bottom of the Edge seminar:

“If i fuck a goat i may feel ashamed if someone saw it, but absent harm to the goat, not clear how i should respond if i alone witness it.”

Behavioral Economics Is Not All That

An excellent editorial today in the NY Times – Economics Behaving Badly by George Loewenstein and Peter Ubel. The basic gist – behavioral economics, while important, has limits; traditional economics still matters greatly for policy; behavioral economics is being used in politics as an avoidance mechanism (hmm, sounds behavioral?) when traditional economic solutions would be better though politically more difficult.

So to repeat:

[Behavioral economics] has its limits. As policymakers use it to devise programs, it’s becoming clear that behavioral economics is being asked to solve problems it wasn’t meant to address. Indeed, it seems in some cases that behavioral economics is being used as a political expedient, allowing policymakers to avoid painful but more effective solutions rooted in traditional economics.

They use two main examples – obesity and conflicts of interest in medicine, like the drug industry giving lavish gifts to doctors.

Take, for example, our nation’s obesity epidemic. The fashionable response, based on the belief that better information can lead to better behavior, is to influence consumers through things like calorie labeling — for instance, there’s a mandate in the health care reform act requiring restaurant chains to post the number of calories in their dishes.

Calorie labeling is a good thing; dieters should know more about the foods they are eating. But studies of New York City’s attempt at calorie posting have found that it has had little impact on dieters’ choices.

Obesity isn’t a result of a lack of information; instead, economists argue that rising levels of obesity can be traced to falling food prices, especially for unhealthy processed foods.

To combat the epidemic effectively, then, we need to change the relative price of healthful and unhealthful food — for example, we need to stop subsidizing corn, thereby raising the price of high fructose corn syrup used in sodas, and we also need to consider taxes on unhealthful foods. But because we lack the political will to change the price of junk food, we focus on consumer behavior.

As they point out, behavioral economics tries to understand how and why people behave irrationally, using elements from psychology to examine deviations from rational choice. The general prescriptions from this policy approach are to manage how options are presented and to present better information so that people better understand the real costs and benefits. Loewenstein and Ubel don’t go so far as to say that these policy solutions still remain rooted in rational man assumptions – individual choice, better information, costs and benefits – but it is rather obvious. And that’s part of the problem.

Behavioral economics reinforces the individual and rational biases there in psychology and economics, rather than addressing community, institutional, and meaningful aspects of people’s lives. In this sense, it’s not too surprising that the pay-off from behavioral economic solutions is not that great.

Prime Minister David Cameron of Britain recently promoted behavioral economics as a remedy for his country’s over-use of electricity, citing what he claimed were remarkable results from a study that reduced household electricity use by informing consumers of how their use compared to that of their neighbors.

Under closer scrutiny, however, tests of the program found that better information reduced energy use by a mere 1 percent to 2.5 percent — modest relative to the hopes being pinned on it.

Compare that with the likely results of a solution rooted in traditional economics: a carbon tax would instantly bring the price of energy into line with its true cost and would unleash the creative power of the marketplace to generate cleaner energy sources.

Still, it’s quite refreshing to have two such distinguished professors saying that what matters is looking at the true costs of things. Nothing irrational about that!

George Loewenstein is a professor of economics and psychology; here’s his webpage in the Department of Social and Decision Sciences at Carnegie Mellon University. You can access a lot of his publications through the live links in his cv – it downloads as a Word document and the one I clicked one then led to a pdf.

Peter Ubel, a physician and behavioral scientist, looks like he’s just moved to become a professor of business and public policy at Duke (he still has a live listing at Michigan’s Center for Behavioral and Decision Sciences in Medicine). But he does have his own website, peterubel.com.

And finally their editorial – Economics Behaving Badly.

Empathy and Neuropolitics


Interesting new piece by Gary Olson, professor of political science at Moravian College. It’s called Empathy and Neuropolitics, with the tagline, “This is your brain on neoliberal culture. Any questions?”

Here’s the abstract:

Mirror neurons, the brain cells believed to be the basis for empathy, have recently been identified in the human brain. And yet we’re left to explain the disjuncture between this deep-seated, pre-reflective, moral intuition and the paucity of actual empathic behavior, especially in certain cultures. I suggest that answers may be found in the bidirectional connection between culture and brain development.

The political theorist William Connally has defined neuropolitics as “. . . the politics through which cultural life mixes into the composition of the body/brain process. And vice versa.” In this context, I hypothesize that the neo-liberal ideology justifying free market capitalism is one of the most potent empathy “bracketing off” elements of that culture and hybrid cultural/neurobiological imprinting can override the neurobiological traits that should bring people together. The dominant culture’s social engineering undermines and attenuates both the acceptance and institutionalization of empathy on a grand scale, while channeling its expression toward system maintenance behaviors.

There are outstanding exceptions, but too many cultural psychologists and other subspecialists have followed too many anthropologists in failing to unpack the meaning of culture itself. Following Gramsci, I argue that power and class realities have not received sufficient attention in explaining what I’ve described as a societal-wide cultural deficit disorder. This pathological condition has structural roots in the socio-economic system which influence the brain’s mirror neuron network. Cross-cultural studies offer a promising avenue for aiding our understanding of this process.

Gramsci and the encultured brain, that’s quite a mix!

Brown Food Revolution

Shannon Horst, the CEO of The Savory Institute, has a good editorial, Africa Needs a Brown (Not Green) Food Revolution, over at the Christian Science Monitor. Rather than more artificial fertilizer and genetically enhanced seeds, of exporting our industrial model to them, she argues for a more local model that improves soil and yields, and works with local environments and knowledge.

She’s definitely on the William Easterly side of things, and against a Jeffrey Sachs type approach – White Man’s Burden: Why the West’s Efforts to Aid the Rest Have Done So Much Ill and So Little Good over The End of Poverty: Economic Possibilities for Our Time.

Here’s the main part of Horst’s Green Revolution critique:

First, scientists are focusing on how to grow bigger, more, and disease- and pest-resistant plants. Their approach views the soil surrounding plants as a “problem” to overcome, rather than the very habitat in which they can thrive. The entire focus is on how to manipulate the plants rather than how to produce both healthy plants and healthy soil… Some 70 percent of Africa’s landscape is grassland – arid, semiarid, temperate, and some tropical. Kenya, for example, is 80 percent grassland. The practices and inputs required to use revolutionary seeds in these lands are destructive… Turning those lands into crop fields will have the same effect it produced on the Great Plains of the United States – the collapse of the grasslands and the soil, river systems, and the groundwater supplies that lie beneath them.

Horst also points out that human resources, embedded in cultures and specific histories, matter:

Most of Africa’s rural populations are pastoralists or agropastoralists who do not farm. Turning them into “productive farmers,” dependent on foreign seeds and other inputs, is not only destructive to their land, it is destructive to their culture. Millions have already been spent by US and European aid organizations throughout Africa on unsuccessful farming programs. Pastoralists in the Horn of Africa consistently say that these programs have also been culturally destructive.

In contrast, Horst and The Savory Institute push for a brown revolution, one that starts with increasing soil quality, and works with environmental and human resources on hand.

What Africa needs is a revolution that mobilizes people to focus on local inputs and practices that produce food that grows in healthy soil (maybe a “brown revolution”) and that enhances the social and economic fabric of the community and nation. Guess what? That brown revolution is possible and sustainable right now…

They have also achieved successful results over the past five years without spending one dime on expensive research into seeds, genetically modified organisms, root manipulation, climate change adaptation, herbicides, fertilizers, or pesticides, and without special planting or harvesting equipment.

Instead, they focus funds on educating local people in practices that blend some older pastoral knowledge and techniques of animal herding with new understanding of how grazing animals, soils, plants, and organisms coevolved and function in a healthy state. Savory’s approach also means building soils, using the seeds and simple tools already available to them, and enhancing the community’s social fabric.

A brown revolution resonates well with what I know of Lesotho, where development has had negative consequences (see James Ferguson’s The Anti-Politics Machine) and where a lack of local employment and farming opportunities, coupled with poor soil and arid conditions, means most Basotho men go to South Africa to work in mines. For more (including photos), see our post on food coping in Lesotho.

So, overall, a very good editorial. There will be roles for fertilizer to improve yields and for plant engineering for greater drought and insect resistance, but imposing such outside solutions simply on the idea that this is what we believe will work, is simply not good enough.

Squirrels as Models for Human Behavior? Indeed!

A delightful article on squirrel behavior, biology, and sociality today highlights just how great a model squirrels can be for some true comparative research. Here’s another species with phenomenal elasticity, good learning and sociality, and even specialized brain and body parts!

Behind the squirrel’s success lies a phenomenal elasticity of body, brain and behavior. Squirrels can leap a span 10 times the length of their body, roughly double what the best human long jumper can manage. They can rotate their ankles 180 degrees, and so keep a grip while climbing no matter which way they’re facing. Squirrels can learn by watching others — cross-phyletically, if need be.

In the acuity of their visual system, the sensitivity and deftness with which they can manipulate objects, their sociability, chattiness and willingness to deceive, squirrels turn out to be surprisingly similar to primates. They nest communally as multigenerational, matrilineal clans, and at the end of a hard day’s forage, they greet each other with a mutual nuzzling of cheek and lip glands that looks decidedly like a kiss.

The gray squirrel is diurnal and has the keen eyesight to match. “Its primary visual cortex is huge,” said Jon H. Kaas, a comparative neuroscientist at Vanderbilt University, A squirrel’s peripheral vision is as sharp as its focal eyesight, which means it can see what’s above and beside it without moving its head.

“We’ve seen seeds that were recached as many as five times,” said Dr. Steele. The squirrels recache to deter theft, lest another squirrel spied the burial the first X times. Reporting in the journal Animal Behaviour, the Steele team showed that when squirrels are certain that they are being watched, they will actively seek to deceive the would-be thieves. They’ll dig a hole, pretend to push an acorn in, and then cover it over, all the while keeping the prized seed hidden in their mouth. “Deceptive caching involves some pretty serious decision making,” Dr. Steele said. “It meets the criteria of tactical deception, which previously was thought to only occur in primates.”

Royal Society Neuroscience and Cognition Articles Free

For the month of July 2010, Royal Society Publishing is providing free access to all their neuroscience and cognition articles.

To give you just one example, here is Joan Chiao & Katherine Blizinsky’s 2010 article (pdf) (sometimes problematic link…). The abstract reads:

Culture–gene coevolutionary theory posits that cultural values have evolved, are adaptive and influence the social and physical environments under which genetic selection operates. Here, we examined the association between cultural values of individualism–collectivism and allelic frequency of the serotonin transporter functional polymorphism (5-HTTLPR) as well as the role this culture–gene association may play in explaining global variability in prevalence of pathogens and affective disorders. We found evidence that collectivistic cultures were significantly more likely to comprise individuals carrying the short (S) allele of the 5-HTTLPR across 29 nations. Results further show that historical pathogen prevalence predicts cultural variability in individualism–collectivism owing to genetic selection of the S allele. Additionally, cultural values and frequency of S allele carriers negatively predict global prevalence of anxiety and mood disorder. Finally, mediation analyses further indicate that increased frequency of S allele carriers predicted decreased anxiety and mood disorder prevalence owing to increased collectivistic cultural values. Taken together, our findings suggest culture–gene coevolution between allelic frequency of 5-HTTLPR and cultural values of individualism–collectivism and support the notion that cultural values buffer genetically susceptible populations from increased prevalence of affective disorders. Implications of the current findings for understanding culture–gene coevolution of human brain and behaviour as well as how this coevolutionary process may contribute to global variation in pathogen prevalence and epidemiology of affective disorders, such as anxiety and depression, are discussed.
