I can't speak to math and theoretical CS, because both of those fields now have methods to make proofs that can be verified (and math is probably the only situation where you can "prove" something true; all other fields are effectively probabilistic, not logical in nature).

I disagree with your premise. Part of our job as scientists (thankfully no longer mine) is to reduce the irrelevant and incorrect noisy as early as possible. I have seen so many grad students get excited by a paper and put enormous effort into reproducing somethign that was a false or fake result.
