FIGURE 10.4 The 16PF: Example Questions and Profiles The 16PF, developed by Raymond Cattell, is a self-report inventory that contains 185 items like those shown in part (a). When scored, the 16PF generates a personality profile. In part (b), personality profiles of airline pilots and writers are compared. Cattell (1973) found that pilots are more controlled, more relaxed, more self-assured, and less sensitive than writers.
