When the going gets tough, the tough get… more relief from a placebo? – “[T]he new findings link specific, established personality traits with an individual’s susceptibility to the placebo effect…. The researchers showed a significant link between certain personality traits and how much relief people said they felt when given the placebo – as well as the level of a specific chemical that their brains released…. The findings show that about one-quarter of placebo response was explained by the personality traits of resiliency, straightforwardness, altruism or anger/hostility, as measured on standardized tests.”

The mysterious Ainu – “[I]s the physical similarity [of the Ainu] to Europeans just a matter of chance? Convergent evolution? No, it may be that the Ainu have just not changed as much physically as other East Asians. – from peter frost.

In Defense of Favoritism – “Affective neuroscience research on early-childhood bonding suggests that, as mammals, we probably start out as emotionally glued microcommunities (family and tribe) before we become autonomous ego-driven creatures.

Privileging your tribe does not render you negative or bigoted toward those outside your tribe.”
