Personality characteristics of a group of white South African managers: Some implications for placement procedures

The usefulness of the E.P.I. as a discriminator between functionally differentiated groups of white managers in South Africa was investigated. The results supported the hypothesis that managers performing jobs of a less routine nature would be more extraverted than managers involved in more routine work. It was suggested that the E.P.I. may have a useful role to play in organizational placement. This supported the conclusions of Eysenck (1967).
