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.

A great idea. Also known as a pre registered study.

Not familiar with this idea, but this idea is commonly applied for grant applications: only apply for a grant when you finished the thing you promise to work on. Then use the grant money to prototype the next five ideas (of which maybe one works), because science is about exploration.

Most pharma / medicine studies are pre-registered now. Sometimes the endpoints change based on what the scientists are seeing, but if they're worth their salt, they still report the original scoped findings as well.

Does not fix the underlying issue. Having a "this does not work" paper on your resume will do little for your career. So the incentives to make data fit a positive hypothesis are still there.

That is categorically not true. Showing why something does not work (or is not advantageous over other methods) demonstrates you know how to properly conduct research which is good for ones resume.

The paper is irrelevant and will never get cited. There is essentially zero benefit to your career as it is nothing more than a single bullet point on your resume.

Discovering something that works is significant, discovering something that does not work is irrelevant.

Can you name a single scientist, e.g. from your field, who is known for showing that something does not work?

I would encourage you to learn more about how science and research is conducted before continuing to make uninformed comments.
