Thanks for all these links! I skimmed them, and it's fun to see that two of them rip into Ionnadis' work, while Ionnadis rips into the Jager/Leek work... It's also a cool exercise in reproducible research and open peer review, both of which are far from common.

In my opinion, the entire exercise of data-mining the published literature is pretty much futile. We already know there are problems in the published literature and that scientists are pretty mediocre at statistics. Pin-pointing the exact value of how mediocre only leads to, as your link shows, a mountain of published works, hurt feelings (on Ionnadis side I guess) and doesn't solve anything.
