INTRODUCTION

CORE DEFINITION

Proposed by Roy Baumeister and colleagues in the 1990s, ego depletion holds that self-control depends on a limited resource that is temporarily reduced by prior acts of restraint, decision-making, or emotional suppression. The theory explains why people who have exerted self-control are more likely to give in to temptation afterward. Key qualification: a large multi-laboratory replication found a much smaller effect than originally reported, so the theory is now contested and treated cautiously.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Schedule by energy: place the tasks requiring most restraint in your highest-energy hours. - Reduce the demand: design the environment so that fewer acts of willpower are needed. - Batch the drain: group demanding decisions rather than scattering them through the day.

Anchor fast decisions

If self-control draws on a depletable resource, then each act of restraint leaves less available for the next, which raises the chance of giving in. An alternative explanation is that motivation and attention shift rather than a resource being consumed, which would produce the same behavior without depletion. The two accounts predict similar outcomes but call for different remedies.

Negging

Negging ("to neg", meaning "negative feedback") is an act of emotional manipulation whereby a person makes a deliberate backhanded compliment or otherwise flirtatious remark to another person to undermine their confidence and attempt to engender in them a need for the manipulator's approval.
