The past, present, and future of ego depletion

At the center of social psychology just a few years ago, ego depletion is now widely seen as a controversial topic, one of the chief victims of the replication crisis. Despite over 600 studies of apparent support, many are now asking if ego depletion is even real. Here, we comment on the articles included in this Special Issue: Ego Depletion. Specifically, we delineate the contributions and limitations of these articles by embedding them in a brief history of ego depletion, describing the current state of uncertainty about ego depletion’s scientific status, and outlining necessary steps for the study of ego depletion to have a healthy future. To us, the most troubling aspect of this controversy is not what is suggests about ego depletion; but what it suggests about social psychology more broadly. If the mere existence of ego depletion is seriously doubted by many, what can be confidently regarded as real in social psychology? By increasing the precision of our theories, continuously validating our manipulations and measures, and practicing the full suite of open science practices we have the potential to identify legitimate and robust effects and build a cumulative and trustworthy psychological science.
