Scholars are "at each other's throats" all the time with respect to the interpretation of data and conflicting theories.
On the other hand, 3rd-party audits of whether a lab is faking data are rare. Your peer scientific investigators take you at your word if you say that you ran a particular experiment and observed a set of measurements.
The idea that "3rd party review" should be commonplace is like the idea that the police should break your door down at their discretion to make sure you are not hiding any illicit drugs. I mean, what is the problem with such "spot checks", especially if you don't use nor traffic illicit drugs, so you have nothing to hide?
Yeah, yeah and yeah, there are bad actors who abuse this trust just as there are criminals who demand their Constitutional Rights in the U.S. system. But yes, the scholarly enterprise is based on mutual trust, and it hence it is such a big deal when someone is caught cheating.
As far as a room-temperature superconductor, as soon as someone announces such a thing, everyone and his brother is running to their lab trying to replicate this result, not just because they are skeptical but also because if this works, they want to "get in on this", maybe writing their own papers if they discover other materials or other ways to get this to work. There was such a gold rush climate with the announcement of liquid-nitrogen temperature superconductors, there was almost immediate confirmation, there was a long period where it was thought not to be practical for engineering applications, but because of the concerted effort of further research over time, such "high-temperature superconductors" have found practical use.
Here, just like with "cold fusion", no one is able to replicate the result. Just like with cold fusion, the people who can't reproduce the result are being charitable, blaming the initial hype on sloppy experimental technique and wishful thinking rather than pointing a finger accusing fraud.
