Ego Depletion: Is Willpower a Limited Resource?
Investigate the ego depletion theory and its ongoing challenges in the realm of psychology and self-control.
What is this page about?
An explainer of ego depletion, Baumeister's 1998 hypothesis that self-control draws on a limited resource so exercising willpower reduces capacity for subsequent self-control, opening with the radish experiment. It covers the strength model versus the process/motivational alternative, four case studies (parole decisions, dietary self-regulation, aggression, workplace ethics), and treats the concept as a central case in psychology's replication crisis, detailing the Hagger et al. 2016 preregistered replication, publication bias, the belief moderator, and the open question of what, if anything, is being depleted.
