The Cutting-edge Science of Self-control (and What to Do About It) | Michael Inzlicht, PhD

Ego Depletion

Michael Inzlicht challenges the traditional theory of ego depletion, which suggests that self-control is a finite resource that diminishes with use. He argues that while we do experience fatigue, the lab experiments supporting ego depletion may not accurately reflect real-world scenarios. Instead, self-control might be more about our willingness to exert effort than a depletable resource 1.

The theory of ego depletion is a limited resource that runs out after use, like fuel in a car.

Trait vs. State

The distinction between self-control as a trait and as a situational state is crucial for understanding behavior. Inzlicht explains that trait self-control refers to a consistent ability across different situations, while state self-control is about moment-to-moment decisions 3. For instance, someone with high trait self-control consistently makes choices aligned with long-term goals, whereas state self-control involves resisting temptations in specific situations.

State self-control is any action, mental or physical, taken to align with long-term goals.

Daily Dynamics

Self-control operates dynamically throughout the day, influenced by psychological and environmental factors. Inzlicht highlights that our ability to regulate ourselves diminishes as the day progresses due to natural rhythms and fatigue 5. This is evident in studies where participants who exert self-control early in the day struggle with similar tasks later.

In the course of a day, you're less able to control yourself at the end versus the beginning.
