Resolute ignorance on race and Rushton

I review Rushton’s research on the evolutionary divergence of the three major human lineages. His life-history theory predicts, and his multiple analyses document, a consistent three-way patterning of mean differences among blacks, whites, and East Asians on coevolved sets of morphological, physiological, developmental, psychological, and behavioral traits. I then analyze a typical example of how critics evaluate his work, including the rate at which they cast his scientific hypotheses, methods and conclusions in politically charged language. The set of articles in question, although authored by well-known academics and appearing in a major, peer-reviewed journal, illustrate how mob science works to “discredit” valid research and enforce collective ignorance about entire bodies of evidence. Rushton is a scholar and gentleman but it appears that his critics often act like neither.

► I evaluate Rushton’s life-history research on the evolution of human races.
► I analyze the content, logic and derogatory terms in typical critiques of it.
► Results show how mob science works to quarantine research on human biodiversity.
► They show how “yes-but” gambits enforce collective ignorance of its evidence base.
