Is there a type 3 error? If not, or if the question is as meaningless as I suspect, why would anyone ever want to use "type 1 error"/"type 2 error" rather than "false positive" and "false negative" (or the other way around, I refuse to look it up)? Is someone golfing research papers, trying to save two characters here and there?

Type 3 error is "giving the right answer to the wrong question" [1] and there are uses for a Type 4 error. This digs into the realm of the "not even wrong" statements.

  In the world of boolean logic this could be expressed as: Type I: true Type II: false Type IV: FileNotFound

  "The wrong question" is subjective though. I meant in the technical sense.
