There's cultural incentive to report results that are favorable even if they are wrong.

This has the unfortunate side effect that research coming out of China needs to be taken with a grain of salt and extra doubly carefully verified.

It's nothing the scientific method can't handle (we're seeing the start of the verification steps here), but knowing that lots of research coming out of China is misrepresented it introduces another layer of healthy skepticism that it needs to be verified before being accepted as a thing.

Suppose University of Shanghai produces a result, and the University of Beijing confirms it. Rather than accept the result, it's likely that before it's declared "SCIENCE!" a NASA or MIT or whoever is going to want to have verification from someplace that doesn't have a long history of misrepresenting scientific claims.

This is going to be treated differently than if the original work was done at say...CERN and the confirmation was done by CalTech.
