Cognitive Abilities and Testing

A total of 101 university students completed the full NEO-PI-R ( Costa & McCrae, 1992 ), assessing the five super-traits (domains) and 30 primary traits (facets), followed by four different cognitive ability tests. Two months later (before receiving feedback on their psychometric scores), they had estimated their own scores on all these variables (personality traits and ability tests), as well as that of a known friend. Results at the Big Five super-factor (domain) level indicated that participants could significantly predict/estimate all their own big five scores, particularly Neuroticism (r = .60). Correlations between estimates of their own intelligence scores and test-derived scores ranged from r = .51 to r = .59. They were, as predicted, much less successful in predicting their friend's scores. At the primary factor (facet) level, participants seemed best at predicting their six Neuroticism scores and less good predicting their six Agreeableness scores. A series of regressions looked at the extent to which self-estimated versus actual (test-derived) Big Five trait scores predicted self-estimated and actual intelligence on each of the four test scores. Self-estimated Conscientiousness significantly predicted various intelligence scores. Stable Open Introverts tended to give themselves higher self-estimates. The possible origins of academic hubris and humility are discussed.
