Ego depletion (limited willpower) turns out not to be true [0]. It could not be replicated and is no longer considered how willpower works.
> Results from the current multilab registered replication of the ego-depletion effect provide evidence that, if there is any effect, it is close to zero. [1]
> Taken all together, experiments conducted at 24 different labs showed no signs whatsoever of Baumeister and Tice’s original effect. [2]
It's a really interesting result because the concept of limited willpower - over extended periods of time (years) - fits my lived experience very well.
