Social investment theory is a psychological theory that claims that changes in personality traits over time are driven by changes in persons' commitments to social roles and institutions. For instance, young adults may undertake efforts to be "more socially dominant, agreeable, conscientious, and less neurotic" in order to establish their careers or families; in so far as society rewards these efforts, the related personality traits are reinforced.
