The repetition team being incompetent sounds like a cop out. The researcher did a bad job and it’s on them to explain better etc in that case. No excuses, if it can’t be reproduced it isn’t taken seriously no exceptions
Furthermore, I think you can often see poorly done science in the papers themselves. They will use suggestive wording in surveys, unreliable sources for sampling such as Amazon Mechanical Turk, and maybe one of the biggest tells is measuring a large number of unnecessary variables. That does very little to further your experiment, but absolutely ensures you can p-hack your way to a statistically significant result. Another is ignoring such patently obvious viable confounding issues, that one can't reasonably appeal to Hanlon's razor.

But this simply isn't true in physics where negative results are very common. This is at least an existence proof that this can work, people just have to get their heads straight on what research means.
On the other hand, it really is the case that there's just not much of any value in learning that [shocking possibility] is, as everybody would naturally expect, indeed not the case. And filling up limited journal space with such discoveries would seem to be counter-productive, at best. And when you have limited space/funding for researchers, one guy who keeps proving everything everybody knows to be false, to be false, is always going to be perceived as less valuable than one making [shocking discovery] [... which ends up being proven false years later].
