      I really dislike the proposal to change the significance threshold from 0.05 to 0.005. There's no principled difference, it's just a number, & it's asking to (eventually) have similar problems. Better solutions are needed, based on a different experimental paradigm.https://twitter.com/JPdeRuiter/status/1046058507500441601 …

      People are often a bit scared of lowering alpha to .005 (see https://www.nature.com/articles/s41562-017-0189-z …), but if you have a real effect, it is easier to obtain than you might think. See http://rpsychologist.com/d3/pdist/  pic.twitter.com/icRbuJ9g8f

      Or to put it a different way: at best this is a stopgap solution.

          Well, all solutions are stopgap solutions. :)

          At 0.05 a human can fudge things around 20ish times to get a result. At 0.005, one would have to write explicit computer code to p-hack, which takes things ethically from grey to black, and can be punished. It's a computationally complexity difference.

          I think it could reasonably be argued to be more than that, because it raises the cost of certain types of bad science much more than the cost of good science, so it should create a lot of circumstances under which the most economically viable strategy is now better science.

          It's not a *great* solution for sure, but changing incentives is more than just a stopgap solution. The real questions are a) does this raise the cost of doing good science too much (it depends.) b) does this make us less likely to adopt a better solution (probably not?)
