> Just say things like "right yes" or "wrong no" and I'll understand. OK. So s/false/right/ and s/right/true/ and s/negative/no/ and s/positive/yes/. Does that work for you? Positive and negative are about the outcome of the test - did it report whatever or not? True and false are about if this result corresponds to reality or not. It might just be me, but "wrong yes" sounds like it's claiming something very specific about the test. It's claiming that test said something was present and it wasn't. It's possible that this might not align with how the test works. Calling it a false positive would seem to make it clear that it's positive from the test's perspective. But I may be wrong! This is clearly just opinion.

I'm not sure I get what distinction you're making. Are you saying that the standard terms don't commit to what we mean by a test's positive/negative, and this generality is more valuable than concreteness? It would be bad to imply too generally that we're talking about a test that says yes or no, a thing is present or absent?

  I'm saying that in my opinion, the standard terms are pretty clear and yes or no create exactly the kind of confusion you're hoping to avoid.

    Huh. Positive and negative are sort of notorious in medical tests for creating a confusion: positive is often bad! There are actually three dichotomies here: was the test mistaken, what was its boolean value, and which boolean value means which thing in the world. Saying yes/no still requires a decision about the latter; though it seems clearer to me about this (both the need for interpretation and on suggesting a default), but it is subjective. And of course, any of these are better than Type I/II. I do kind of insist that right/wrong or correct/mistaken clearly means the first question, where true/false is more ambiguous. To really resolve things maybe a better idea is like wrong/present and right/absent.

      I've found that the pronunciation of English tends to dissociate the words "positive" and "negative" from their proper meaning, which has led to all sorts of misuse of the words. The following pronunciation isn't 'correct' English pronunciation, but try 'mispronouncing' it that way a few times (out loud) and see if that flips a switch in your head: Po‑si–t—ive & Ne‑ga–t—ive. po‑si–t—ing & ne‑ga–t—ing. Po‑si–t—ed & Ne‑ga–t—ed. Po‑si–t—ive‑ly & Ne‑ga–t—ive‑ly. Gives a whole new meaning to the idea of 'positive' and 'negative' numbers, doesn't it?
