Just in case it takes me another 3 years to get back to this, here are preliminary & exploratory (!) results from #zcurve using #FReD2.0. Expected Replicability Rate (ERR) is overestimated in most cases. Creating samples where the actual replicability rate (RR) is 0 reveals a strong overestimation.

Assumption Checking Prevents Assumption Hacking in Multiverse Meta-Analyses - Replicability-Index In a nutshell Statistical methods for meta-analyses make different assumptions. For this reason, different methods can produce different results with the same data. Meta-analysts often struggle to mak...

Who could have predicted this. 600 studies and no real effect. #Zcurve of Ego Depletion studies. The data are from 2016.
