Reproducibility project fails to validate dozens of biomedical studies

This doesn’t really surprise me at all. It’s an unrelated field, but part of the reason I got completely disillusioned with research to the point I switched out of a program with a thesis was because I started noticing reproducibility problems in published work. My field is CS/CE, generally papers reference publicly available datasets and can be easily replicated… except I kept finding papers with results I couldn’t recreate. It’s possible I made mistakes (what does a college student know, after all), but usually there were other systemic problems on top of reproducibility. A secondary trait I would often notice is a complete exclusion of [easily intuited] counter-facts because they cut into the paper’s claim.

To my mind there is a nasty pressure that exists for some professions/careers, where publishing becomes essential. Because it’s essential, standards are relaxed and barriers lowered, leading to the lower quality work being published. Publishing isn’t done in response to genuine discovery or innovation, it’s done because boxes need to be checked. Publishers won’t change because they benefit from this system, authors won’t change because they’re bound to the system.

All it takes is 14 grad students studying the same thing targeting a 95% confidence interval for, on average, one to stumble upon a 5% case. Factor in publication bias and you get a bunch of junk data.

I think I heard this idea from Freakonomics, but a fix is to propose research to a journal before conducting it and being committed to publication regardless of outcome.
