This paper examines how accurate people are at estimating their own psychometric test results, which assess personality, intelligence, approach to learning and other factors. Seven groups of students completed a battery of power (general intelligence, fluid intelligence, creativity and general knowledge) tests and preference (approaches to learning, emotional intelligence, Big Five personality) tests. Two months later (before receiving feedback on their psychometric scores) they estimated their own scores and that of a class acquaintance who they claimed to know well on these variables. Results from the different samples were reasonably consistent. They showed that participants could significantly predict/estimate their own Neuroticism, Extraversion and Conscientiousness scores, as well as their General, Fluid and Crystalised intelligence, Approaches to Learning, Creativity and Happiness. Correlations between estimated and test-derived scores for an acquaintance were around half those for self-estimates and better for personality than ability. Participants self and “other” estimates were nearly all significantly positive. The discussion considers when, if ever, self-estimated scores can be used as proxy for test scores and what self-estimated scores indicate. Limitations are considered.
