When do psychopathic traits affect cooperative behaviour? An iterated prisoner’s dilemma experimental study
Personality traits have been long recognised to have a strong impact on human decision-making. In this study, a sample of 314 participants took part in an online game to investigate the impact of psychopathic traits on cooperative behaviour in an iterated Prisoner’s dilemma game. We found that disinhibition decreased the maintenance of cooperation in successive plays, but had no effect on moving towards cooperation after a previous defection or on the overall level of cooperation over rounds. Furthermore, our results underline the crucial importance of a good model selection procedure, showing how a poor choice of statistical model can provide misleading results.

Abstract

Personality traits have been long recognised to have a strong impact on human decision-making. In this study, a sample of 314 participants took part in an online game to investigate the impact of psychopathic traits on cooperative behaviour in an iterated Prisoner’s dilemma game. We found that disinhibition decreased the maintenance of cooperation in successive plays, but had no effect on moving towards cooperation after a previous defection or on the overall level of cooperation over rounds. Furthermore, our results underline the crucial importance of a good model selection procedure, showing how a poor choice of statistical model can provide misleading results.
