On each field of knowledge you can find more than one heterodox PhD or professor. So a list of selected quotes can be sampled quickly. William B. Shockley, 1956 physics nobelist for having developed the transistor, is on record for stating that Blacks are for genetical reasons dumber than Whites. Should I be impressed? Does him being a physics Nobelist make his statement any truer? I do not value much the opinion of a peace Nobelist when she talks about science.
