1975MYCIN: type WHY and it says why it is asking; type HOW and it says how it reached a conclusion. Davis, Buchanan and Shortliffe, Stanford.
See also: SHRDLU answers 'why did you do that?' with its goal: 'TO CLEAN OFF THE RED CUBE' (Winograd, MIT, January 1971).
“Because the consultation process is essentially one of search through an AND/OR goal tree, ... WHY a question was asked, and HOW a conclusion was (or will be) reached.”
MYCIN's guesses are about a patient, not about you, so it is the ancestor of asking a machine why.
