Is Personal Intelligence Related To Maladaptive Interpersonal Behavior?

Being able to identify problematic personality expression has been rising in importance—especially given personality profiles of individuals engaging in violent events—hate crimes, shootings, and the like. If we become better capable of assessing groups of people who experience symptoms that may predispose them to such acts—and to helping them, we can improve the quality of life for those individuals and the ones around them. Some individuals exhibit what has become known as “dark triad” traits: Machiavellianism, narcissism, and psychopathy. Machiavellianism is defined as a focus on self-interest and personal gain with an inherent disregard of morality. Narcissism is defined as a pursuit of self-glorification and vanity with disregard of others. Psychopathy is defined as a general form of behavior deviancy accompanied by an emotional-interpersonal detachment. The present research examines whether low levels of the ability to recognize and use information about personality to understand oneself and others may contribute to those traits. The ability to understand such personality characteristics is labeled personal intelligence. Other personality traits related to such interpersonal behaviors also have been identified. We hypothesize that those low in personal intelligence, low in honesty/humility, and in other traits, are more likely to exhibit dark triad traits and have a general lack of understanding of themselves and others. The Test of Personal Intelligence (TOPI 5G), the Short Dark Triad, the Dirty Dozen, the HEXACO-PI-R, and the Balanced Inventory of Desirable Responding Short Form will be administered to participants to find potential correlations between the scores on the scales.
