Abstract:

Ego depletion leads to preference for immediate interests and goals, which is likely to induce irrational decision making. Based on systematic literature reviews, ego depletion impedes rational decision making through two mechanisms. In regard to the attention mechanism, depleted individuals are more likely to be attracted by immediate rewards but ignore the importance of long-term benefit (i.e., failure of “focusing on the future”). In terms of the execution mechanism, depletion impairs individuals’ abilities of planning and executing (i.e., failure of “sticking to the future”). Moreover, two critical boundaries affect such processes: (1) individual characteristics, including susceptibility to resource depletion and internal moral restraint; (2) situational characteristics, including external provocation, social norms and decision costs. Future research should adopt eye tracking technology to extend the research in attention mechanism and explore other boundary conditions, which helps to nudge rational decision making.

Key words: ego depletion, decision making, rationality, attention mechanism, execution mechanism, long-term benefit
