Abstract
In a prior study psychopathic individuals showed a diminished level of cooperativeness but realized higher individual rewards in a prisoner’s dilemma game, compared with community controls. The present study replicated this finding with professional bank traders, who exhibited less cooperative behavior than both of the aforermentioned groups (community controls and psychopathic patients). While the bank traders did not obtain a higher gain than the psychopathic individuals at an absolute level, they maximized the discrepancy between their own profit and the yield of their anonymous computerized gaming partner. The bank traders were more prone than psychopathic patients to rely on strategies that considerably harmed the profit of their gaming partners without necessarily optimizing their own total profit. The community controls achieved the same overall gain as traders and psychopaths. Unlike traders and psychopathic patients, the normal controls balanced overall gains of themselves and their game opponent, which led to the highest overall profit, whereas the traders achieved the lowest overall profit.
