The Bell Curve wasn't simply descriptive. It contained "policy implications based on these purported connections [between IQ and race]." It opened by saying that if you want to hire good employees, you should hire by IQ... and then connected IQ to race, implying that racial discrimination is justified. On examination, many of the sources were directly tied to white supremacist organizations.

The Bell Curve is a singularly poor example of a scientific description of the status quo attracting unfair attacks.
