    Preregistered multisite experiment across 36 samples using depletion tasks selected by proponents of the theory.

    Key Findings

    Depletion effects were very small and not statistically robust across sites.

    Conclusions

    Evidence for a general resource-depletion account of decision fatigue is weak.

    Limitations

    Laboratory tasks may not capture real-world decision load.
