I’m surprised it’s a year already since posting my published comments on the ASA Document on P-Values. Since then, there have been a slew of papers rehearsing the well-worn fallacies of tests (a tad bit more than the usual rate). Doubtless, the P-value Pow Wow raised people’s consciousnesses.

Times Sunday Rev. at 2 (Jan. 4, 2015). Is there anything […]
1. What does it mean for a debate to be “media driven” or a battle to be “lost by the media”? In my last post, I noted that until a few weeks ago, I’d never heard of a “power morcellator.” Nor had I heard of the AAGL–The American Association of Gynecologic Laparoscopists.

There are some ironic twists in the way social psychology is dealing with its “replication crisis”, and they may well threaten even the most sincere efforts to put the field on firmer scientific footing–precisely in those areas that evoked the call for a “daisy chain” of replications.
