In 1959, psychologists Festinger and Carlsmith conducted an experiment that showed how a small payment could change people's beliefs about boring tasks. Participants were asked to lie, telling others the tasks were enjoyable—but here’s the twist: those paid only $1 ended up believing the lie more than those who got $20. Why? The $1 group needed to justify their fib to themselves since the reward wasn’t big enough to excuse the lie. This experiment reveals the surprising way our minds handle guilt and justification!
