You take what you can as a consumer of information, trying to make sense of things. Sailer spends more time on Nicholas Wade than I think is warranted. Wade says ethnic groups are the product of 50,000 years of evolutionary pressure. And with the DNA research being done in recent years there is a lot to study and consider. But Wade does not explain how so many blacks a person comes across in every day life are indistinquishable, behavior and ability wise, from others. Based on Wade you would expect stark differences between people who maintained a hunter gatherer lifestyle and the Asians and Europeans who settled into structured communities.
