Here's what I distracted myself with this morning. Don't mix these at home. Wired Sci examines how Testosterone Makes People Suspicious of One Another. And that's a hell of a photo. New Flu Vaccines Could Protect Against All Strains If all goes well, of course. Not to count on at this point, but an interesting look at one direction in vaccine development. I covered another approach in an Technology Review article last year, when I also looked at the weird history of adjuvants. (If you want, check out my complete vaccine coverage. You can find also some other good ones at the Technology…
The English language is full of metaphors linking moral purity to both physical cleanliness and brightness. We speak of "clean consciences", "pure thoughts" and "dirty thieves". We're suspicious of "shady behaviour" and we use light and darkness to symbolise good and evil. But there is more to these metaphors than we might imagine. The mere scent of a clean-smelling room can take people down a virtuous road, compelling them to choose generosity over greed and charity over apathy. Meanwhile, the darkness of a dimmed room or a pair of sunglasses can compel people towards selfishness and…
Not long ago I was out at a dinner of climate activists, at the beginning of a conference I was at, and as we were climbing into the car of one of the program leaders, there was talk about whose car was messier. This is a competition I always win - I mentioned to them that not only do I have little kids in my car, messing it up, but I drive goats around in my Taurus. Several people asked me why I drive goats in a car, (which even to me seems like a reasonable question). The answer is that I am a farmer with goats, but I don't have a pick up truck, so when they go to be bred or to the vet,…
What do you think a group of women would do if they were given a dose of testosterone before playing a game? Our folk wisdom tells us that they would probably become more aggressive, selfish or antisocial. Well, that's true... but only if they think they've been given testosterone. If they don't know whether they've been given testosterone or placebo, the hormone actually has the opposite effect to the one most people would expect - it promotes fair play. The belligerent behaviour stereotypically linked to testosterone only surfaces if people think they've been given hormone, whether they…
This article is reposted from the old Wordpress incarnation of Not Exactly Rocket Science. The blog is on holiday until the start of October, when I'll return with fresh material. As a species, we value fair play. We're like it so much that we're willing to eschew material gains in order to punish cheaters who behave unjustly. Psychological games have set these maxims in stone, but new research shows us that this sense of justice is, to a large extent, influenced by our genes. When it comes to demonstating our innate preference for fair play, psychologists turn to the 'Ultimatum Game',…
Some people go out of their way to help their peers, while others are more selfish. Some lend their trust easily, while others are more suspicious and distrustful. Some dive headlong into risky ventures; others shun risk like visiting in-laws. There's every reason to believe that these differences in behaviour have biological roots, and some studies have suggested that they are influenced by sex hormones, like testosterone and oestrogen. It's an intriguing idea, not least because men and women have very different levels of these hormones. Could that explain differences in behaviour between…
If a colleague of yours was rewarded for their work while you received nothing for your (similarly sized) efforts, you would probably be quite peeved. Now it seems that man's best friend also shares our disdain for unfairness. Humans are notorious for our dislike of injustice. It rankles us to see others being rewarded or penalised unfairly. We not only have the capacity to recognise when someone else is being rewarded beyond their efforts, but the inclination to punish them for it, often at personal expense. But other species behave in the same way - recent studies have found that capuchin…
A stranger walks up to you and a friend and offers to give you both £100. As always, there is a catch - your friend must choose how to split the money between you. Accept his offer, and you both keep your respective shares; reject it, and you both come away empty-handed. Now imagine your friend offered you a single pound. What do you do? Most people would reject the offer to spite the friend. Even though you would financially better off if you accepted, you friend's proposal is unfair and rather insulting. Clearly, economic status is not the only thing at stake here. Psychologists use…
Yesterday, I wrote about selfless capuchin monkeys, who find personal reward in the act of giving other monkeys. The results seemed to demonstrate that monkeys are sensitive to the welfare of their peers, and will make choices that benefit others without any material gain for themselves. Today, another study looks at the same processes in a very different sort of cheeky monkey - human children. Humans are notable among other animals for our vast capacity for cooperation and empathy. Our concern about the experiences of other people, and our natural aversion to unfair play are the bedrocks…
There are some who say that helping others is its own reward, and many biologists would agree. The fact that selfless acts give us a warm glow is evident from personal experience and neurological studies, which find that good deeds trigger activity in parts of the brain involved in feelings of reward. But feeling food by being good isn't just the province of humans - monkeys too get a kick out of the simple act of giving to their fellow simians. At the Yerkes National Primate Research Center, Frans de Waal's team of scientists have been investigating the selfless side of eight brown capuchin…
Social lives are delicate things. We've all had situations where friendships and relationships have been dented and broken, and we're reasonably skilled at repairing the damage. This ability to keep our social ties from snapping relies on being able to read other people, and on knowing a thing or two about what's normal in human society. For instance, we appreciate that cheating fosters ill-will, while generosity can engender trust. So cheaters might try to win back their companions with giving gestures. These little exchanges are the glue that bind groups of people into happy and…
