Sian Jarvis, the supermarket’s head of corporate affairs, had undermined her claims to care about the health of her customers and let slip one of the secrets of a multi-billion-pound industry ... she revealed that one in three Asda checkouts “are what we call guilt-free checkouts”. Jarvis insisted “guilt-free” was merely “a term that’s commonly used in retail”. But it was too late, and her “guilt” gaffe quickly invited scorn in the industry and among public health professionals. Whatever the damage, she had already opened a door to the arcane science of supermarket psychology. To the designers of the modern store, shoppers are lab rats with trolleys, guided through a maze of aisles by the promise of rewards they never knew they sought The Secrets Of Our Supermarkets [more inside]

The Anternet is always up. On the surface, ants and the Internet don't seem to have much in common. But two Stanford researchers have discovered that a species of harvester ants determine how many foragers to send out of the nest in much the same way that Internet protocols discover how much bandwidth is available for the transfer of data.

A chronic public health disaster.
Complex trauma and toxic stress puts children into a state of reflexive fight, flight, or freeze responses to a perpetually threatening world. The traditional authoritative response only serves to reinforce those behaviours and, perhaps worse, has long-term health consequences:
With an ACE score of 4 or more, things start getting serious. The likelihood of chronic pulmonary lung disease increases 390 percent; hepatitis, 240 percent; depression 460 percent; suicide, 1,220 percent.
One doctor describes it as “a chronic public health disaster”. Remediating this problem is going to require listening, kindness, and parachutes.

Anger, Politics and the Wisdom of Uncertainty
- "If there's somebody or even some institution to blame, it turns out people are much more likely to get angry... anger tends to inspire individuals to engage in more political activities than they would otherwise... Without someone to blame, respondents mostly just grow fearful and anxious... A particular danger of anger seems to be closed-mindedness. Research finds that when citizens get angry, they close themselves off to alternative views and redouble their sense of conviction in their existing views. Fear and anxiety, on the other hand, seem to promote openness to alternative viewpoints and a willingness to compromise." (via

humans are dumber than chimps. These guys
show (at the NY Times level) that human kids will over-imitate every ritualized nuance modeled for them, whereas chimp kids just wanna get the damn cookie out of the box. Their website also describes more

How dogs became man's best friend: Dr Hare's hypothesis is that dogs are superbly sensitive to social cues from people...
His experiment was simple. He presented his animal subjects with two inverted cups. Then he hid the cups behind a screen, put a small piece of food under one of them, and took the screen away. The animal had to choose which cup to look under. If the experimenter gave no cue, both species got it right 50% of the time, as would be expected. However, if he signalled in some way which was the right cup, by pointing at it, tapping it, or even just gazing at it, a dog would choose correctly every time, while a chimpanzee would still do only slightly better than chance.

Monkeys down tools
. - Demand fair pay for a fair day's work
" Researchers taught brown capuchin monkeys to swap tokens for food. Usually they were happy to exchange this "money" for cucumber.
But if they saw another monkey getting a grape - a more-liked food - they took offence. Some refused to work, others took the food and refused to eat it.

I yearn for your tasty flesh
[ Gene Study Finds Cannibal Pattern ] - "Deep in the recesses of the human heart, lurking guiltily beneath the threshold of consciousness, there may lie a depraved craving — for the forbidden taste of human flesh.
The basis for this morbid accusation, made by a team of researchers in London, is a genetic signature, found almost worldwide, that points to a long history of cannibalism" (NYT)

Becoming Evil: How Ordinary People Commit Genocide and Mass Killing
: "To offer a psychological explanation for the atrocities committed by perpetrators is not to forgive, justify or condone their behavior. Instead, the explanation simply allows us to understand the conditions under which many of us could be transformed into killing machines." (James Waller) In a Salon interview
about his widely acclaimed, pathbreaking book Waller states, "Most people don't understand how easy it is to develop us-them [mindsets]......In our climate of fear in response to terrorism, I think we could pretty easily turn on people who have been our neighbors."
