There are measurable statistically significant differences in IQ (even for culture blind tests) between different ethnic groups that are primarily caused by genetics. This is not about the superiority of one race over another; it’s about understanding the world better. It is a good indicator to understand wealth differences between nations, for example. There have even been studies, such as the Minnesota Transracial Adoption Study, that show that these differences in IQ persist between different ethnic groups, regardless of socioeconomic factors. James Watson, the discoverer of DNA, had to sell his Nobel prize for stating approximately the above, for he was censored, hence this post.
