The nature of the relationship between job characteristics, personality, and job satisfaction was investigated. A longstanding debate exists between psychologists that believe structural characteristics of the job are the primary determinants of job satisfaction (Kulik, Oldham, & Hackman, 1987; O'Reilly & Roberts, 1975) and those that believe personal attributes of the worker are most important (Hackman & Lawler, 1971; Pervin, 1968). Information was collected from 163 participants on the Job Characteristics Inventory, the Myers‐Briggs Type Indicator (Form G), and the satisfaction scale of the Job Diagnostic Survey. Hierarchical regression analyses demonstrated that job characteristics successfully predicted job satisfaction (average Ra2 =.30). A series of hierarchical regressions indicated that personality had neither a direct effect on satisfaction nor a moderating effect on the job characteristics‐job satisfaction relation. These results indicate that, at least as measured by the MBTI, the characteristics of the individual may be of little importance during job redesign.
