What? There's a definite difference between "Whoops, I accidentally measured this wrong back in the day, sorry" vs "I'm covering up that I'm measured this wrong".
From a moral point of view there is. My point is that from the point of view of science the same self-correction should work in both cases, so the bigger story to "somebody lied" is that "in case of this attractive lie the self-correction didn't work well".
