Think fast, not deep
Watching the end of Family Feud and one of the questions was "Name a state where you think the buffalo used to roam."
Now, that is a tricky question. Whatever your answer, it can't be wrong; you could *think* they used to roam in Hawaii and score points if other people also think it.
But what does "used to roam" imply? One of them said "Minnesota," which strikes me as not a bad answer for fact-ness. (The other said New York, which is also true.) But Montana was the number 1 answer, and they *still* roam there, so I wouldn't have said it.
Of course, "used to" doesn't' have to mean "still doesn't", though I think Grice implies it.
The trick is not to overthink it, I guess. Plus, you only get 4 seconds a question.
