The general factor of personality and general intelligence: Evidence for substantial association

Article history: Received 8 December 2012 Received in revised form 18 May 2013 Accepted 11 June 2013 Available online 6 July 2013 Despite theoretical assertions derived from life history theory, research on the relationship between the general factor of personality and general intelligence has shown that there is little overlap between the two higher-order constructs. It is argued that the association between these general factors is largely attenuated by measurement error in assessing the general factor of personality. A substantial association between the general factors at multiple points in time was found when the general factor of personality was derived from rater Q-sorts. The results have important implications for the study of individual differences. © 2013 Elsevier Inc. All rights reserved.
