**Abstract:** Can differences in cognitive reflection explain other-regarding behavior? To test this, I use the three-item Cognitive Reflection Task to classify individuals as *intuitive* or *reflective* and correlate this measure with choices in three games that each subject participates in. The main sample consists of 236 individuals who completed the *dictator game, ultimatum game* and a *third-party punishment task.* Subjects afterwards completed the three-item Cognitive Reflection Test. Results showed that *intuitive* individuals acted more prosocially in all social dilemma tasks. These individuals were more likely to serve as a norm enforcer and *third-party punish* a selfish act in the *dictator game*. *Reflective* individuals were found more likely to act consistently in a self-interested manner across the three games.

**Keywords:** social preferences; third-party punishment; cognitive reflection ability; intuition; reflection; dictator game; ultimatum game
