The Biology of Stupidity: Genetics, Eugenics and Mental Deficiency in the Inter-War Years

It may be thought that the title of this paper betrays a regrettable lack of sensitivity and good taste; it is as well, therefore, to explain its origin. Lewis Dexter was, I think, the first sociologist to apply a deviance perspective to the high-grade mentally retarded. ‘On the Politics and Sociology of Stupidity in Our Society’ argues that our discriminatory attitudes to the retarded have deep ideological roots; our social institutions tend ‘automatically’ to penalize stupidity; and repugnance often characterizes our face-to-face interactions with the stupid. The pejorative label ‘stupid’ was justified precisely because identifying the stupid is a ‘commonsense’ rather than a scientific process, although commonsense does not have long to wait before it is bolstered by science.
