That's the statistical theory, but what is the reality? I would be very surprised if 95% of results are accurate. We would need a study of reproducibility across other fields - and of course a study that reproduces the Reproducibility Project. > it's not hacked (or the papers go through selection effects) There are many, many reasons, besides 'hacking' or selection effects, for results that aren't 100% accurate.
