Since people are often wrong, assuming a particular mistake is not always that much off a hypothesis (given available information), but the person suspected of error will often notice the false positives more saliently than they deserve, instead of making a correction, as a purely technical step, and moving forward.
The observation that people are often wrong applies similarly to both the hypothesis that a specific error is present and the hypothesis that a specific correction is optimal. Expecting a conversation partner to take either of those as given is incorrect in a very similar way to expecting a conversational partner to take a particular hypothesis’s truth as given. Clear communication of the logic behind a hypothesis (including a hypothesis about wrongness or correction) is generally necessary in such situations before that hypothesis is accepted as likely-true.
