The relationship between Manifest Anxiety and intelligence was evaluated by means of a design which attempted to control such variables as heterogeneity of intelligence and presence of psychopathology. The Ss, 100 "normal' and 100 "neurotic,' were similar in age and education. They were approximately normally distributed with respect to intelligence test scores. The results suggest that considerable caution must be exercised in interpreting any relationship between intelligence and Manifest Anxiety. Although no significant relationship was demonstrated, the present statistical results illustrate that faulty control of relevant variables may have contributed to some of the apparent significance of past research.
