Several years ago, I bought this book from an antique store. I love finding old psych and psych-adjacent books. But I bought this book not for its contents, but for the pamphlets stuck inside it. Seems relevant to these discussions on the dangers of IQ testing. A pic thread. Image A "Code of Ethics", right beside an article on sterilization, from the American journal of mental deficiency. Irony. Image

Posterior passing assumes a few things I'm not sure are discussed enough here. Mainly, that there is a singular parameter. In the end, this mode of posterior passing basically becomes a fixed-effect meta-analysis. To that end, I actually think a better comparison would be > between posterior passing, fixed effects MA, random effects MA, both bayesian and non-bayesian versions. Comparing a pseudo meta-analytic method to ones that don't claim to do so, and arguing for how well it converges to the generative value seems a bit obvious to me.
