99% Impossible: a Valid, Or Falsifiable, Internal Meta-Analysis

Researchers are increasingly relying on internal meta-analysis (IMA) to document cumulative evidence. We demonstrate that even minor violations of the assumptions underlying IMA invalidate its results—and once established—a false-positive IMA is practically impossible to falsify. We conclude that IMA should be used exclusively for pre-registered many-lab replications.
