Abstract in brief

The concept of ego depletion suggests that willpower relies on a limited mental resource, potentially glucose, that gets exhausted after acts of self-control, but this idea faces theoretical challenges and mixed experimental results.
Researchers used a new meta-analytic method called p-curve analysis to assess the reliability of the evidence, finding that the reported effect sizes may be biased and that the overall evidential value is weak.
Due to these findings, the authors recommend that researchers and policymakers avoid concluding that glucose directly influences self-control until more robust evidence is available.]
