The ego depletion theory once looked like one of the most solid ideas in psychology. From the 1998 experiment in which students who ate radishes in a room full of chocolate aroma gave up on puzzles faster, through hundreds of supporting studies, to the 2016 reversal in which a joint replication by 23 labs and over 2,000 participants reported an effect of essentially zero. This installment traces how a theory backed by hundreds of papers can collapse — by running a publication bias simulation with your own hands.
