Seven individuals having a 47, XYY chromosome were correctly distinguished from 28 individuals drawn from the general population by means of a double blind psychological evaluation (including TAT and Rorschach). The prevalence of XYY men, unscreened for height, was 1 per 1000, and for those screened for height, was 3.5 per 1000. Greater stature and certain psychological characteristics were found among the XYY group. However, there was no evidence of below‐average intelligence or criminality.
