I’ve decided to take Richard Lynn up on his 2010 challenge:
“If a multiracial society is found where these race differences in intelligence are absent, the evolutionary and genetic theory of these differences would be falsified. Those who maintain that there are no genetic differences in intelligence between the races are urged to attempt this task.”
As such, I’m going to start collecting new data (i.e., from 2000 on), starting with secondary data, on the ethnic gaps in multiethnic societies. If you’re aware of any good sources feel free to let me know. I am generally only interested in data which includes a standardized measure of ability. I’m going to take my time on this, so this post will be continually updated until I find a society that substantially falsifies Lynn’s evolutionary hypothesis.
