Note on small p-value hacking by Thomas Lumley [outside article]


The proposal to change p-value thresholds from 0.05 to 0.005 won’t die. I think it’s targeting the wrong question:  many studies are too weak in various ways to provide the sort of reliable evidence they want to claim, and the choices available in analysis and publication process eat up too much of that limited information.  If you use p-values to decide what to publish, that’s your problem, and that’s what you need to fix.
