Brain scans have shown that when people see faces of other races, their amygdalas light up like home security systems. Some tout this as evidence of hardwired racial bias, evolved to keep the oddly colored “other” out of home territory. But as Robert Wright points out in this recent article, there would be few opportunities for interracial conflict in our geographically dispersed evolutionary past. The “other” would primarily be distinguished by different visual cues such as tribal emblems, because hostile neighboring tribes would generally be of the same race.
More recent brain scan experiments done on children show that, like menstrual cramps and unstoppable boners, neurological race rage doesn’t kick in until after puberty. While the question of “nature vs. nurture” is still open, this suggests that cultural forces are at work.
Wright’s line of reasoning is pretty solid when he says, “[T]hough we’re not naturally racist, we’re naturally ‘groupist.’”
