I know, I know, I’m obsessed with p-hacking. If you’re tired of reading about the undermining of many of the scientific results in psychology over the past several decades, I’m sorry, but this paper is just too good:
“The designing, collecting, analyzing, and reporting of psychological studies entail many choices that are often arbitrary. The opportunistic use of these so-called researcher degrees of freedom aimed at obtaining statistically significant results is problematic because it enhances the chances of false positive results and may inflate effect size estimates.”
This is an instruction manual to commit, or to detect, p-hacking.
