TLDR
The size of the ego-depletion effect was small with 95% confidence intervals (CIs) that encompassed zero (d = 0.04, 95% CI [−0.07, 0.15]), and implications of the findings for the psyche depletion effect and the resource depletion model of self-control are discussed.

The Ideological-Conflict Hypothesis
Decades of research in social and political psychology have demonstrated that political conservatives appear more intolerant toward a variety of groups than do political liberals. Recent work from
