It’s been almost a half decade since the replication crisis in psychology broke, and one of the major casualties was the subfield of ego depletion. (I belive this was the initial large scale meta-analysis that found no effect. And here is a popular article on the failure to replicate.)
Does anyone have a good summary of the state of that research program? Is there any part of it that held up? What can we conclusively say about self control, willpower, depletion of mental resources, etc?
