Abstract This paper reports three studies designed to look at the usefulness of the Perception and Preference Inventory (PAPI). The first study looked at the fakeability of the PAPI by asking one group to fake good, another to fake bad, and a third group to respond honestly. Just over hald of the items yielded significant differences between the three groups, with most differences being between the fake bad and control group. In the second study the PAPI was correlated with the Eysenck Personality Questionnaire. Extraversion-Introversion and to a lesser extent neuroticism was correlated with PAPI subscores, particularly the dimensions of work direction and work style. Five of the seven subscale scores from the PAPI were correlated with extraversion. In the third study the PAPI was correlated with the Baddeley Reasoning Test, which is itself correlated with many intelligence tests. There were very few significant correlations. Implications for the measurement of personality and individual differences in occupational and industrial settings are considered.
