The purpose of this study was to examine the simultaneous relationships among intelligence, personality, and vocational interests. The study sample was composed of 874 individuals aged 14 to 83. Intelligence, personality, and vocational interest were measured using the Kaufman Adolescent and Adult Intelligence Test, Myers-Briggs Type Indicators, and Strong Interest Inventory respectively. A canonical correlation analysis was performed between each pair of instruments. Overall, the results of the study indicate modest relationships among the domains of intelligence, personality, and vocational interests. The relationships observed in the present canonical correlation analyses between intelligence and both personality and vocational interests reflect overlap with general ability, especially the kind that is associated with schooling and overall acculturation experiences. The relationships do not seem to denote an overlap with fluid ability, the kind of intelligence that is demonstrated when people are able to solve novel problems that are largely unaffected by schooling; nor do the relationships seem to donate correspondence to intellectual abilities that are less saturated with "g" (general intelligence), such as short-term memory or visual-spatial ability. Whereas the areas of overlap should help professionals interpret the measures jointly, the results affirm that none of the measures are redundant with each other and all have much uniqueness to contribute to an assessment of an adolescent or adult.
