What is the most accurate modern assessment of the ego-depletion theory discussed in Chapter 3?

Answer & explanation

It proposes prior self-control can impair later self-control, but replication evidence is mixed and its generality remains debated

The ego-depletion hypothesis proposes that exerting self-control on one task reduces later self-control, sometimes described as drawing on a limited resource. Kahneman recounts evidence favoring this idea, but later preregistered multilab experiments reported smaller or nonsignificant effects under some protocols. The takeaway is to distinguish what the book argued from how confidently current evidence supports a general depletion effect.
