You may be more prejudiced than you think, especially if you?re angry and approached by someone of a different race, religion or creed.
February 9, 2004
The police killing of an unarmed 19-year-old on a Brooklyn rooftop last month appears to be a tragedy of nanoseconds and eons, a death delivered by a cop firing not because of a conscious decision but an instantaneous neuronal impulse hardwired from the days of our animal ancestors.

What motivates our choices? Is it reason? Emotion? Biological instinct? Social norms? Is the moral satisfaction of doing right enough to tempt us away from the material rewards of doing wrong?
January 21, 2004
What accounts for the persistent belief that trade with poor countries will make us worse off? Recently, it occurred to me that evolutionary psychology might provide the answer.
January 19, 2004
Some people say a face is like an open book. For psychologist Paul Ekman, the face is more than that, it's the Rosetta stone of human evolution. (Audio interview requires RealPlayer.)

An unusual experiment with monkeys who were switched between mothers shortly after birth has demonstrated the importance of nature over nurture in behavior.
November 26, 2003
Fossil bones record the history of the human form but they say little about behavior. A richer source on the way human social behavior evolved may come from chimpanzees, with whom people shared a common ancestor as recently as five or six million years ago. (May require free registration.)

Feminists might be surprised to hear it, but females are the dominant sex in most primate communities. Far from being passive bystanders in a world governed by machismo, a new study suggests females may determine social evolution in primates.
November 25, 2003
Several million years before Bonnie Fuller ditched Jann Wenner's Us Weekly to remake David Pecker's Star tabloid into a shiny celebrity magazine, life on the African savanna had already sculpted the human psyche into a vessel that would thirst for page after page of articles about the mating rituals, health, and drug problems, fertility problems, wealth and status displays.

If races are defined as genetically discrete groups, no. But researchers can use some genetic information to group individuals into clusters with medical relevance.
November 17, 2003
A new Dartmouth study reveals that interracial contact has a profound impact on a person's attention and performance. The researchers found new evidence using brain imaging that white individuals attempt to control racial bias when exposed to black individuals, and that this act of suppressing bias exhausts mental resources.
November 14, 2003
Two recent studies of African baboons provide new insights into the complexity of monkey social behavior. This research may in turn reveal the conditions that contributed to the evolution of distinctly human traits, such as language and certain strategies for survival.
October 6, 2003
When a nation's overall levels of religious belief and attendance are high, its citizens voice greater disapproval of divorce, homosexuality, abortion and prostitution—issues involving sexual morality. But religiosity is less likely to spur such disapproval for cheating on taxes or accepting bribes in public office, says two Penn State researchers.

A speech at the American Enterprise Institute by Lionel Tiger, Darwin Professor of Anthropology at Rutgers University. His "principal focus is on the set of working principles and facts speaking for themselves, which compose the idea of 'human nature.' "
September 29, 2003
Humans are social animals, but does our social organization result from our genetic makeup or does it come from something much more fundamental? From her work studying social insects, Arizona State University biologist Jennifer Fewell believes that these remarkable animals suggest a an alternate cause behind the development of complex societies.

The discovery of just a single bacterium somewhere beyond Earth would force us to revise our understanding of who we are and where we fit into the cosmic scheme of things, throwing us into a deep spiritual identity crisis that would be every bit as dramatic as the one Copernicus brought about in the early 1500s, when he asserted that Earth was not at the center of the universe.
September 18, 2003
Knowing when you have been ripped off is not solely a human skill, biologists have discovered. Monkeys can spot a raw deal when they see one, and if they are not treated fairly they throw a tantrum. The finding confirms the idea that cooperative behaviour, which relies on the participants' having a sense of fair play, appeared early in our evolutionary history.

Languages evolve and compete with each other much like plants and animals, but those driven to extinction are almost always tongues with a low social status, U.S. research shows.
September 5, 2003
Many positive aspects of modern human society are the fruit of millennia of cooperative interactions between members of our species. Yet the evolutionary origins of cooperative behaviour in social animals and insects remains one of the most intriguing puzzles in biology. Now scientists have observed the real-time evolution of novel forms of cooperative behaviour between bacterial cells in the laboratory.

The Moral Sense Test is a Web-based study into the nature of moral intuitions developed by the Primate Cognitive Neuroscience Laboratory at Harvard. How do humans, throughout the world, decide what is right and wrong? To answer this question, participants evaluate a series of moral dilemmas designed to probe the psychological mechanisms underlying our ethical judgments. The test takes about 10 minutes and participation is completely confidential.

Michael Shermer's column in the September issue of Scientific American examines recent evidence that, like bonobos, we may be evolving in a more peaceful direction.
August 13, 2003
The idea that people are connected through just "six degrees of separation," based on Stanley Milgram's "small world study," has become part of the intellectual furniture of educated people. New evidence discovered in the Milgram papers in the Yale archives, together with a review of the literature on the "small world problem," reveals that this widely-accepted idea rests on scanty evidence.
August 8, 2003
An e-mail experiment has confirmed the famous 'six degrees of separation' of human social networks, but revealed that individuals don't necessarily benefit from their connectedness.

Much has been written about the glass ceiling, the double standard and other barriers to women in management. A related question that has consumed both academic and popular writers is whether men and women have the same leadership abilities. The answer suggested by a comprehensive meta-analysis published in the current Psychological Bulletin (Vol. 129, No. 3) might surprise you. On average, women in management positions are somewhat better leaders than men in equivalent positions, according to the study.

Empathy is what we all claim we want more of—from our spouses, our bosses, our friends and, perhaps especially, our harried doctors. But what is it, exactly? Does it truly aid healing to be understood? Do empathizers run the risk of burning out if they care too much? And how, if empathy is such a good thing, can we get—and give—more of it?

Is mankind doomed? Against the background of the war against terror, the march of technology and environmental calamity, this has become the defining question of our age.
July 24, 2003
The important thing about religion, David Sloan Wilson thinks, is that it encourages collective action. The emotions that religions build on, and the conduct they encourage, tend to bind groups and build cooperation. The worship of a common god, he believes, is really the worship of a common good, to whom everyone in the tribe or religion must defer.
July 18, 2003
Researchers have worked out why tit-for-tat jostles so swiftly escalate into fisticuffs: humans routinely underestimate the force they exert when pushing or hitting other people.

Feel under seige from a vocal religious culture? Maybe you're a Bright. A Bright is defined as a person whose worldview is naturalistic (free of supernatural and mystical elements). Although they differ in many ways, there are lots and lots of people who have such a worldview. An umbrella group for those with a naturalistic worldview is being formed. Members include Daniel Dennett and Richard Dawkins. And perhaps you too?
July 3, 2003
Research by economists at two American universities suggests that, even in the job market, women behave in ways that disadvantage them. At the University of Chicago's business school, Uri Gneezy and a group of colleagues have used novel techniques to show that women and men have different attitudes to competing.

June 23, 2003
And as companies race to build better gadgets and gizmos to improve our daily routines, a part-human, part machine organism comes closer to becoming reality. But it seems, at least in some circles, that we became full-fledged cyborgs long ago. Technology is inseparable from who we are and how we think, argues Andy Clark in his new book, Natural-Born Cyborgs.
June 20, 2003
Blue-throated lizards that help each other achieve reproductive success are also helping scientists understand how social cooperation evolved. Most examples of cooperative behavior in animals involve cooperation between genetically related individuals, which is explained by the theory of "kin selection." Now, researchers have described an example of cooperation between genetically similar but unrelated members of a lizard species common in the western United States. Their findings, published in the June 20 issue of the journal Science, shed new light on the evolution of cooperation and social behavior.

From the BBC comes three radio programs on the history of human folly. Francis Wheen examines the perennial tendency of politicians, scientists and others in authority to act perversely, and how, when more rational alternatives are clearly present, the best and brightest can blithely and arrogantly march into colossal blunders. You can listen to the broadcasts over the 'Net.

There is no earthly reason that readers should care about the drama that has unfolded over the turf war between the Greater Kansas City Chamber of Commerce and the smaller Chambers of Commerce in Johnson County. Yet, like many conflicts that seem petty to those who are uninvolved, to those who are involved, the issues trigger rage, suspicion, fear, and other deeply passionate emotions that prove, once again, our human systems are programmed oftentimes to fight, particularly over a perceived threat over turf.
June 10, 2003
We've been obsessed with human nature ever since we knew we had one. And we 've fought fierce intellectual battles and even real wars trying to impose different versions on each other. The irony was that much of what we thought we knew was wrong or at best problematic. But now, uniquely, barriers are coming down and disciplines joining forces for what will be a truly epic journey.

Lucky people frequently experience the small-world phenomenon, and that such "lucky" meetings have a dramatic and positive effect on their lives. In contrast, unlucky people rarely report such experiences.
June 9, 2003
Some of the most provocative new findings about the origins and worldwide spread of the human species are coming from studies of the history books packed inside nearly every cell of our bodies. Genes speak volumes about our beginnings in Africa an estimated 130,000 to 200,000 years ago, our divergence into distinct populations of hunter- gatherers and farmers, our migration into Europe and Asia, and finally our settling in the Americas, perhaps 30,000 years ago.

Apart from population--larger countries tend to have more terrorists--the only variable that was consistently associated with the number of terrorists was the Freedom House index of political rights and civil liberties. Countries with more freedom were less likely to be the birthplace of international terrorists. Poverty and literacy were unrelated to the number of terrorists from a country.

An interview with philosopher Galen Strawson. "Almost all human beings believe that they are free to choose what to do in such a way that they can be truly, genuinely responsible for their actions in the strongest possible sense; responsible period; responsible without any qualification; responsible sans phrase, responsible tout court, absolutely, radically, buck-stoppingly responsible; ultimately responsible, in a word - and so ultimately morally responsible when moral matters are at issue. Free will is the thing you have to have if you're going to be responsible in this all or nothing way. That's what I mean by free will. That's what I think we haven't got and can't have."

Terrorists appear to share several biopsychosocial traits with war heroes--with some important distinctions, Dr. Ansar Haroun said at a special session of the annual meeting of the American College of Forensic Psychiatry. Drawn from interviews with suspected terrorists captured in Afghanistan during Operation Enduring Freedom, Dr. Haroun's observations were in aid of shaping a framework of understanding about such individuals, and, if possible, shedding light on the murky psychiatric study of terrorism.

Social exchange is cooperation for mutual benefit. It is an "I'll scratch your back if you scratch mine" principle: X provides a benefit to Y conditional on Y doing something that X wants. This very basic form of cooperation is zoologically rare -- it occurs in only a handful of species. But it is as characteristic of human beings as language and tool use.
August 5, 2002
We’re wired by evolution to want to connected to the group. But to stay connected, our brain must reward us for cooperative behavior. Now researchers at Emory University in Atlanta have used brain imaging to show just how cooperative behavior triggers that subtle ‘high’ we all seek.
