Maybe not so independent after all: The possibility, prevalence, and consequences of violating the independence assumptions in psychometric meta‐analysis

Psychometric meta‐analysis assumes that moderators are unrelated to study artifacts (e.g., criterion reliability), and that study artifacts are independent of true validities. Meeting these assumptions is important for researchers seeking to accurately partition the variance in effect sizes due to study artifacts from the variance due to meaningful moderators. Despite the critical role of these assumptions, we know very little about their...
