Similarly, agreeableness is a personality trait that is related to the consideration of others' mental states. [9] The finding that IQ predicts work performance, academic achievement, and health might also point to a link between intelligence and personality, or else be grounds for further research into their relationship.

The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by the psychologist Richard J. Herrnstein and the political scientist Charles Murray in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance ...
Typical intellectual engagement (TIE) is a personality construct referring to a person's enjoyment (or dislike) of intellectually demanding activities. [1] TIE was developed to identify aspects of personality most closely related to intelligence and knowledge and measures a person's typical performance in intellectual domains rather than their maximal performance (intellectual capacity ...
Personality traits are not significantly correlated with the intelligence as process aspect except in the context of psychopathology. One exception to this generalization has been the finding of sex differences in cognitive abilities, specifically abilities in mathematical and spatial form. [46] [49]
The mean correlation of IQ scores between monozygotic twins was 0.86, between siblings 0.47, between half-siblings 0.31, and between cousins 0.15. [ 79 ] The 2006 edition of Assessing adolescent and adult intelligence by Alan S. Kaufman and Elizabeth O. Lichtenberger reports correlations of 0.86 for identical twins raised together compared to 0 ...
As a result, correlations between personality and behavior increased substantially, and it became clear that "personality" did in fact exist. [69] In 1992, the NEO PI evolved into the NEO PI-R, adding the factors "Agreeableness" and "Conscientiousness", [57] and becoming a Big Five instrument. This set the names for the factors that are now ...
The associations between intelligence and personality have generally been interpreted in two main ways. The first perspective is that personality traits influence performance on intelligence tests. For example, a person may fail to perform at a maximal level on an IQ test due to his or her anxiety and stress-proneness.
Intelligence tests and psychometrics have generally found high correlations between different aspects of intelligence, rather than the low correlations which Gardner's theory predicts, supporting the prevailing theory of general intelligence rather than multiple intelligences (MI). [54]
