Jacobson, and Li-Jun Ji Queen’s University Abstract Researchers have proposed that the emergence of religion was a cultural adaptation necessary for promoting self-control. Self-control, in turn, may serve as a psychological pillar supporting a myriad of adaptive psychological and behavioral tendencies. If this proposal is true, then subtle reminders of religious concepts should result in higher levels of self-control. In a series of four experiments, we consistently found that when religious themes were made implicitly salient, people exercised greater self-control, which, in turn, augmented their ability to make decisions in a number of behavioral domains that are theoretically relevant to both major religions and humans’ evolutionary success. Furthermore, when self-control resources were minimized, making it difficult for people to exercise restraint on future unrelated self-control tasks, we found that implicit reminders of religious concepts refueled people’s ability to exercise self-control. Moreover, compared with morality- or death-related concepts, religion had a unique influence on self-control.

For example, in a study supporting the similar human evolution by promoting a myriad of socially beneficial idea that religious concepts, such as the concept that God exists, behaviors (Baumeister, Bauer, & Lloyd, 2010; Henrich & can serve basic psychological needs to perceive the social world Henrich, 2006; Norenzayan & Shariff, 2008).
