this study was based out of the UK.
jeesh....
it is great that they took the time to track kids born in 1958 and again in 1970 and gave them IQ tests at age 10 or 11, and then gave them IQ tests again at age 30, but.....
my guess is that their end goal is to get rid of racism or prejudices that make it easier to tax middle class whites and give the money to poor blacks....so their end goal is to make it easier to spread socialism.
back when I was trying to go to grad school for psychology, I was involved with running students through surveys that measured their individualistic vs. collectivism tendencies. the same study was going on in India, and if I recall correctly also in Ireland.
you could see where being a more collectivistic culture would make it easier to become communists/socialists.
