Finished teaching my new Advance Stats for Psych graduate course today with a heavy emphasis on both DAGs and shifting away from coefficient interpretation and towards models as prediction machines. Both went great! The latter was extremely helpful for logistic regression (for obvious reasons 😵💫)!

If the average power of a test in a discipline is ~20% and 1% of published results are nulls, then there is almost no plausible way to work out the math so you don’t see absolutely *enormous* amounts of selection on significance. Sig results are always over like 100x favoured
