I don't know of another human who has been researching this as long as Thomas Sowell. He has made predictions about culture and the welfare state that have come true decades later. In the scientific world, being able to observe phenomena, make a hypothesis and accurately predict results is the gold standard.

I find it illogical that you care so little about the actual data and so much about the race and nationality of the researcher. What does a researcher's nationality or skin colour have to do with data research? Are you suggesting that only Canadians can study Canada? What is your basis for this claim?
