The idea that some groups of people may be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran is prepared to say it anyway. He is that rare bird, a secientist who works independently of any institution. He helped popularize tha idea that some diseases not previously thought to have a bacterail cause were actually infections ,which aroused much controversy when it was first suggested.
Even he, however,might tremble at the thought of what he is about to do.

They also suffer more often than most people from a number of nasty genetic diseases, such as breast cancer. These facts , however, social effects, such as a strong tradition of valuing education. The latterwas seen as a consequence of genetic isolation .Dr.Cochran suggests that the inteligence and diseases are intimately linked. His argument is that the unusual history of these people has subjected them to unique evolutionary pressures that have reasulted in this paradoxical state of affairs.
