   Fact-check: corrected the Hagger et al. (2016) replication result (no significant depletion effect; d=0.04, CI includes zero), qualified the parole-board study as observational, and reframed 'decision-making reliably degrades judgment' as contested given the 36-lab null.

   Before

   Hagger 2016 showed a significant depletion effect; parole-board data proves judges were depleted; decision-making reliably degrades subsequent judgment.

   After

   Hagger 2016 found NO significant depletion effect (d=0.04, 95% CI [-0.07,0.15]); the parole-board study is an observational association; sustained decision-making MAY degrade judgment but this is contested (36-lab null, d=0.06).

   Why: Independent fact-check against Hagger et al. 2016 (Perspect Psychol Sci), Danziger et al. 2011 (PNAS), and Vohs et al. 2021.
