Children and racial preference

Cognitive Daily has a very nice discussion of the cognitive biases of children involved in identifying and evaluating races. One of the results was that "racial preference" decreases over time.

Obligatory disclaimer: there are no human races, just geographical and genetic variation that is reinforced by social assortation. The "race" here is a social construct. What is interesting is that these social constructs appear to have some foundation not in biological differences among people, but in the sorts of superficial markers used to identify groups.
