It gets scary when scientists are attacked for asking questions
which don't meet current political sensibilities, or for asking
them in terms that don't.

Recall the first guy who said that the sun might not revolve around
the earth...

Talk about 'double-think.' We have folks who insist that Darwin,
not Genesis be taught in schools. Then we have folks who insist that
evolution of different intellectual abilities on different continents
cannot have occurred.

They probably wouldn't know what the term 'adaptive significance'
means if it bit them on the ass.

Of COURSE folks whose ancestors lived tens of thousands of years
in the African plains would have developed different hard-wired
perceptual skills than those who evolved in Bolton, UK. Different
'gifts' if you want to put it in spiritual terms. Problem is, the
IQ tests were developed by the (relatively recent) folks from
Bolton. With major perceptual (vs. intelligence) elements.

In practice, I'd bet that people arrive at the same conclusions
(objective truth) via different routes.

Then again, we've done so much genetic mixing that it is probably
hard to find the hard-wired differences that relate to skills in
bringing down a zebra vs. a woolly mammoth.
