Possibilities
"When you have eliminated the impossible, whatever remains, however improbable, must be the truth." This is true as far as it goes. But there are always an infinitude of remaining possibilities, of varying degrees of improbability. You can't begin to think of most of them. And you definitely shouldn't assume that the first one that comes to your mind must be the one correct one.
We are very tired of doctors who, having failed to find a probable cause of a symptom by anything they can test for, jump to some conclusion about something that wouldn't show up on any test they can think of... and insist that that MUST be THE answer.
