edyong | March 2, 2009I live in London. According to Google Analytics, 96% of this blog's readers make their homes in a different city and 91% live in another country altogether. The fact that most of you are reading this post at all is a symptom of the globalised state of the 21st century.
Through telecommunications, the Internet, free trade, air travel and more, the world's population is becoming increasingly connected and dependent on one another. And as this happens, the problems that face us as a species are becoming ever more apparent, from our relentless overuse of natural resources to the threat of…
ddobbs | February 27, 2009I drove up to Montreal yesterday, and amid visits with anthropologist and Somatosphere founder Eugene Raikhel, anthropologist Allan Young, and Suparna Choudhury, talked about (among other things) the emerging new area of study they're calling "critical neuroscience."
What the heck is critical neuroscience? Well, one definition calls it
the attempt to assess and inform neuroscientific practice from a rich interdisciplinary perspective, and to categorize, evaluate and (begin to) manage the various risks resulting from neuroscience and its results and applications

Both objects and behaviour can be described as disgusting. The term could equally apply to someone who cheats other people out of money as it could to the sight of rancid food or the taste of sour milk. That's not just a linguistic quirk. Some scientists believe that the revulsion we feel towards immoral behaviour isn't based on our vaunted mental abilities, but on ancient impulses that evolved to put us off toxic or infectious foods.
It seems that your facial muscles agree. Hanah Chapman from the University of Toronto has found that both physical and moral disgust cause the levator labii…
edyong | February 26, 2009During elections, what affects our decision to vote for one politician over another? We'd like to think that it's an objective assessment of many different factors including their various policies, their values, their record and so on. But in reality, voters are just not that rational.
In the past, studies have shown that people can predict which of two politicians will win an election with reasonable accuracy based on a second-long looks at their faces. With a fleeting glance and little purposeful consideration, people make strong judgments about a candidate's competence, that can sway…
edyong | January 23, 2009It's been a big week. With a simple words, Barack Obama became the first black President of a country whose history has been so haunted by the spectre of racial prejudice. His election and inauguration are undoubtedly proud moments but they must not breed complacency. Things may be changing outwardly, but problems remain.
For a start, it goes without saying that many people, even the most liberal and left-wing among us, still harbour unconscious prejudices against members of other races. These "implicit biases" may be hidden, but their effects are often not. For example, a study published…
edyong | January 8, 2009Picture the scene - you sit in a room with two other people, one white and one black, waiting for a psychological test. As the black person leaves to use their mobile phone, they bump the knee of the white person on their way out. While they're gone, the white person turns to you and says, "Typical, I hate it when black people do that." How would you feel? Would you be shocked? Angry? Indifferent? And would you want to work with that person later?
This was the scenario that Kerry Kawakami from York University used to try and understand the state of race relations in 21st century America.…

When battles are waged over values and ideologies, you can't bribe or reason your way to peace. That's the stark message from a new psychological study of people in the heart of the Israeli-Palestinian conflict.
The fight over the land of Israel/Palestine has raged for over a century and the peace process has been difficult, lengthy and often stagnant. All the while, lives continue to be lost in skirmishes and suicide attacks, as the past weeks have painfully demonstrated. Perhaps it's time to put the situation under some scientific scrutiny.
A huge number of modern conflicts are…

"Control - you must learn control!" These wise words were uttered by no less a sage than Yoda, and while he was talking about telekinetically hoisting spacecraft, having control has another important benefit. It protects a person from spotting false patterns that aren't there, from believing in conspiracies and from developing superstitions.
Control and security are vital parts of our psychological well-being and it goes without saying that losing them can feel depressing or scary. As such, people have strategies for trying to regain a sense control even if it's a tenuous one. Jennifer…
edyong | December 23, 2008Three years ago, Lawrence Summers, former president of Harvard University, claimed that genetic differences between the sexes led to a "different availability of aptitude at the high end". His widely derided led to his dismissal, but is views are by no means uncommon. In the same year, Paul Irwing and Richard Lynn conducted a review of existing studies on sex differences in intelligence and concluded:
"Different proportions of men and women with high IQs... may go some way to explaining the greater numbers of men achieving distinctions of various kinds for which a high IQ is required, such…
edyong | December 8, 2008We tend to think of race as a fixed part of our identity, a trait that is set at the moment of conception and stays unchanged for our entire lives. But a new study shows just how fluid our conceptions of race can be.
By following a group of people over almost two decades, Andrew Penner and Aliya Saperstein from the University of California, Irvine found that the way people identify themselves racially, and the way others define them, change over time and are coloured by social status. Their study strongly argues that race is as much a flexible indicator of our social standing as it is a…
edyong | November 26, 2008Throughout our language, the vocabulary of physical cleanliness is also used to describe moral cleanliness. We describe saints as pure and thieves as dirty; consciences can be clean and sins can be washed away. But more and more, psychological studies tell us that these concepts are entwined in a very real way. The act of cleaning, or even just thinking about the concept of cleanliness, can influence a person's moral compass, swinging it towards a less judgmental direction.
This isn't the first time that I've blogged about this. Two years ago, Chen-Bo Zhong and Katie Liljenquist found that…
edyong | November 20, 2008Imagine walking through a neighbourhood and seeing graffiti, litter, and shopping trolleys strewn about the place. Are these problems to be solved, or petty annoyances that can be ignored in the light of more serious offences? A new study suggests that the former is right - even the most trivial of transgressions can spread and spiral because their very presence stimulates more of the same behaviour. Through a series of stunning real-world experiments, Kees Keizer and colleagues from the University of Groningen have shown that disorder breeds more disorder. The mere presence of graffiti, for…
edyong | September 18, 2008When we're suddenly confronted with a shocking image, our skin becomes moist and we blink strongly. These actions are automatic and unintentional; they happen without conscious thought. So it may come as a surprise that they can also predict some of our most seemingly considered beliefs - our political attitudes.
According to a new American study, the stronger these responses, the more likely people are to support the Iraq War, Biblical truth, the Patriot Act and greater defence budgets. Conversely, people who show weaker "startle reflexes" are more likely to support foreign aid, immigration…

On 14 January 2005, Lawrence Summers (right), president of Harvard University spoke of the reasons behind the disproportionate lack of women in top-end science and engineering jobs. Avoiding suggestions of discrimination, he offered two explanations - unwillingness to commit to the 80-hour weeks needed for top level positions and, more controversially, a lower "intrinsic aptitude" for the fields. According to Summers, research showed that genetic differences between the sexes led to a "different availability of aptitude at the high end".
For years, scientists have battled over the…

Elections are weighing heavily on our minds. In three short months, America will see the race between Barack Obama and John McCain come to a head, while we in Britain will probably have a general election within the next few years. Some people, of course, will vote based on long-held loyalties to a specific political party, but many of us are more malleable in our choices. What affects the choices of these undecided voters?
People are given to viewing ourselves as rational beings and as such, we'd like to think that our choices are fuelled by objective and careful deliberation. So we pay…

People in most parts of the world are living longer and longer, thanks to great leaps in medicine and sanitation over the last century. But these growing life expectancies bring with them a sense of unease. The biggest worry is the possibility that medical advances are artificially prolonging life with little regard for its quality. Old age, after all, brings with it an increased risk of chronic diseases such as cancer, as well as both physical and mental decline.
This is not just a moral question, but an economic one too. The "oldest-old" are the fastest growing demographic in…

"Out, damn spot! Out I say!" In Macbeth's fifth act, Lady Macbeth's role in the treacherous murder of Duncan takes its toll, and she begins obsessively washing her hands to alleviate her guilty conscience. Now, some four centuries after Shakespeare penned his play, scientists have found that physical and moral cleanliness are just as inextricably linked as he suggested.
The link between bodily cleanliness and moral purity is evident throughout the world's cultures. Cleansing ceremonies are common in religions. Christians and Sikhs literally wash away their sins through baptism, while…

"This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn't the small green pieces of paper that were unhappy." - Douglas Adams
In this pithy paragraph, the sorely missed Douglas Adams sums up a puzzling paradox of modern life - we often link happiness to money and the spending of it, even though both proverbs and psychological surveys…
edyong | March 19, 2008Two weeks ago, I wrote about a Science paper which looked at the effects of punishment in different societies across the world. Through a series of fascinating psychological experiments, the paper showed that the ability to punish freeloaders stabilises cooperative behaviour, bringing out the selfless side in people by making things more difficult for cheaters. The paper also showed that 'antisocial punishment', where the punished seek revenge on the punishers, derails the high levels of cooperation that other fairer forms of punishment help to entrench.
Now a new study published in that…

Humans have an extraordinary capacity for selflessness. We often help complete strangers who are unrelated to us, who we may never meet again and who are unlikely to be able to return the favour. More and more, we are being asked to behave in selfless ways to further the common good, not least in the race to tackle climate change.
Given these challenges, it's more important than ever to understand the roots of cooperative behaviour. From an evolutionary point of view, it can be a bit puzzling because any utopic society finds itself vulnerable to slackers, who can prosper at the expense of…
