Answer:
What Alan Goodman is saying is true.
Race, for a long time, was a concept that was accepted, not only by the scientific community, but also, by society at large.
With time, the concept of human race was found to be a biological myth, a social construct, and while this kind of thinking is true in the scientific community, in society, many people still believe that human races are real.
For this reason, a paradigm shift is required: a radical change in the way we understand and study human differences from a scientific and social point of view.
