You can’t fix it in infants. The bias comes from a fundamental fear of the unknown, different races are more unknown than your own (mostly). As a child grows, other races become less unknown and that “branch” of bias falls off.
The title of the relevant paper discussed in your link is “Olderbut not younger infants associate own-race faces with happy music and other-race faces with sad music” [emphasis mine]
If it were an ‘in utero’ phenomenon, the reverse would be expected–younger, but not older, infants would make the association. (Or, there would be no effect of infant age).
I’ve changed my mind, this has to be a clumsy troll job. Nobody earnestly posts that many articles in support of their arguments that they clearly haven’t read and that directly undermine the claim they’re making. It’s impossible.
It’s all cool. I think this thread is making everyone batty actually. I was actually serious about the hike, I was never able to get any good pictures but I saw primates swinging in the trees on the first day before we cleared the primary forest area.
So… being a slave stresses you out? Multiply that times a few generations and the epigenetics select for stressed out unhealthy people (sickle cell for example).
The interesting thing about sickle cell is it evolved as a mechanism to
prevent Malaria. You only need one sickle cell gene to be malaria
resistant, but two causes the disease, likely because of the host of other
issues that come with it. Malaria is so prevalent in Africa, it’s not
surprising.
On the other hand, predisposition to hypertension, cardiovascular disease
and diabetes, to me, signals a possible oversecretion/high receptor
affinity for stress hormones that lead to high blood pressure and
hyperglycemia. If you were a slave, like you said, that makes plenty of
sense. Seeing as my great-great grandparents had the potential to be
slaves, we’re not that far removed from those possible epigenetic changes.
