When to cooperate and when to compete: Emotional intelligence in interpersonal decision-making

This study examined the relationship between emotional intelligence (El), assessed with an ability test, and interpersonal decision-making using the Prisoner's Dilemma Game (PDG). Previous research found that individuals who self-report high El tend to cooperate more than others in the Prisoner's Dilemma. We relativize these findings by showing that individuals scoring high on an ability measure of El choose effective strategies to deal with three different PDG conditions during real interactions. This suggests that emotionally intelligent individuals are not rigidly predisposed to cooperate regardless of others' behavior. Instead, El is associated with the capacity to respond flexibly to others' strategies and to the interaction context in order to maximize long-term gains - even when this means competing rather than cooperating.
