More about false positives

This feels like a similar topic to the previous post: If someone asks me if such-and-such is correct and I can only answer in terms of good or bad (e.g. my mouth is full and I can give a "thumbs up" but cannot say "correct") then I say "good" as a substitute for "correct". The good/bad axis and the correct/incorrect axis are neither orthogonal nor co-linear.
