That is correct as far as it goes, and here is where it stops going. Yes, and the corollary is less popular: if the reasoning holds, it also holds where it produces an answer we do not like.
Worth separating that from the trial evidence, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.
If somebody has the primary source to hand I would rather cite it than paraphrase it.
