I have something that sorts my incoming work before I see it, and a while back I let it start learning from what I did afterwards. Replied, acted on, ignored, deleted. It adjusts what it puts in front of me next time. It works, roughly. But I keep hitting the same wall: I am a bad teacher and I have no way to tell it so. A week where I am underwater looks exactly like a week where nothing mattered. A Sunday cleanup where I clear a pile of things in four minutes teaches it that the whole pile was unimportant, when really I was just tired of looking at it. And the things I avoid because they make me uncomfortable are often the ones I should have opened first, so it learns to hide precisely the wrong stuff. I have patched the obvious cases. Anything cleared in a big batch counts for less. Age is taken into account before an ignore counts as a judgement. But those are guesses about my own behaviour, and I have no way to check whether the guesses are any good. What I keep landing on is that the signal is cheap and abundant and mostly meaningless, and the signal I actually want, did this turn out to matter, arrives weeks later if at all, and never in a form anything can read. So: anyone here letting a system learn from your behaviour rather than from your instructions? How do you stop it learning your bad weeks? Or have you tried it, decided it was not worth it, and gone back to writing the rules yourself?
