Science & Health Benefits of Belief in God & Religion | Dr. David DeSteno

About this video

Psychologist Dr. David DeSteno argues that whether God exists is not a useful scientific question because science cannot prove or disprove it, and he cautions against scientists claiming certainty either way. Huberman introduces Dr. DeSteno as studying morality, religion, and the health benefits of belief and prayer without promoting religion. Dr. DeSteno discusses brain mechanisms behind faith, rituals versus superstition, religions versus cults, and why few of the many new religions endure. In his cheating research, Dr. DeSteno describes a rigged coin-flip task where participants could claim an easier task: he reports about 85 percent lied in one version, and about a third cheated even when told they must follow the coin. He says people then invent stories to preserve a view of themselves as good, illustrating how reputation and being observed shape moral behavior.
