When the scores obtained with the WISC battery of tests from children attending a psychiatric clinic were compared with those obtained from normal children, they showed a greater dispersion. Attempts to explain the discrepancy in terms of selection, non‐normality, or emotional and environmental factors, proved unconvincing. An application of Bartlett's formulae for the sampling theory of ability suggested that the difference might be due to genetic factors arising from pronounced assortative mating.
