The whole framing of meta-analyses as the pinnacle of reliability is sort of concerning. They're a huge help with messy questions like "what the hell is up with priming?", but between choosing which studies to include, standardizing their controls, normalizing their results, etc. it's amazing how far they can be skewed.

One thing I don't know: what does preregistration even look like for a metaanalysis? You can state some conditions up front, but a lot of the degrees of freedom only come into play once you're deep in the work looking at specific studies.
