57. Will Gervais on the Origins of Religion, Disbelief, and Morality

“Humans didn’t evolve to believe in gods — we evolved to learn from culture, and sometimes culture points away from gods.”


Dr Will M. Gervais, psychologist and author of Disbelief, joins Humanism Now to examine one of the most persistent puzzles in the study of religion: why a species capable of deep religiosity also produces millions of convinced non-believers. Drawing on cultural evolution, cognitive science, and cross-cultural data, Will shows why belief and disbelief are shaped less by raw rationality than by social signals, security, and learning environments.
