There are big temperament differences in newborns that seem to foreshadow what we think of as cultural differences.>> Landmark studies on racial differences in temperament in human neonates (already referenced on this list) and breed differences in puppies were both conducted by Daniel Freedman. To recap briefly, the studies of humans found that Asian neonates were much less active than Blacks, with Whites falling in between. A spin-off then found that Amerind neonates were most like Asians, supporting the Bering Strait migration hypothesis. Freedman's 1958 study of puppies looked at whether one could effect their going to a dish of food after the experimenter had disciplined them for doing so (and then observed them through a 1-way mirror). Shelties, a breed selected for its ability to inhibit aggression and to instead herd sheep, refused to go to the dish and almost starved themselves to death. Basenjis, an active hunting breed, started to wolf down the chow almost as soon as the experimenter turned his back. Two other breeds, beagles and fox terriers, responded differentially to the experiment based on whether their earlier training had been indulgent or strict (no such breed X training interaction was found for basenjis or shelties). So my question is to what extent do race differences in school achievement and job success reflect differences in temperament, as much as in g or learning ability? I'm not saying there are no cognitive differences, but only that temperament may also play a role, and one easier to accept and to adjust for -- especially given that for most of history the American elementary school system was largely run by 'old spinsters'. Perhaps one reason groups like Blacks, on average, perform better in areas like sports, entertainment, and the military than in academics is that the former are better suited to a more active, extraverted temperament. That's just one of the many reasons why I think our 'one-size-fits-all' school system needs to be completely overhauled. --------------------------------------- Freedman, D.
