UNSOCIAL SCIENTISTS--"Are the social traits that characterize so many scientists to be regarded as defects of personality bordering on the abnormal? The answer is no. Mental or emotional breakdowns were no more common among scientists than among nonscientists in our gifted sample of the population. At any rate, in our gifted group the physical scientists and engineers are at the opposite pole from the businessmen and lawyers in abilities, in occupational interests and in social behavior. These basic personality differences may well account for much of the current friction between scientists and the government officials who are responsible for their security clearances and for the restrictions imposed upon them."
