Until the advent of the genetic research that gave birth to Ancestry DNA and 23andMe, a lot of people took Franz Boaz and his "race is a social construct" fallacy seriously. However, when 23andMe can pick the one Icelander out of a blind sample that includes one Icelander and 10,000 Bantu tribesman -- with 100% accuracy -- Boaz's "race is a social construct" hypothesis is laughed to scorn by any reasonable person.

And how about Bayesian Clustering? When assigned a value of k=3 (without using reference panel data), Bayesian Clustering of genetic data selects random individuals and separates them into the 3 racial groups commonly recognized for more than 100 years: Caucasian, Negro, and Mongoloid. Therefore Boaz's Fallacy is now totally debunked.
