Is tarot actually accurate?
Change the question first: tarot is not a prediction instrument, it is closer to a mirror. The cards supply a set of structured pictures, and what makes them “accurate” is the moment you see them — what you recall, what you admit. The same Tower reads as “this needs to stop” for one person, usually because he already knew and simply never allowed himself to say it.
So do not ask whether it is accurate; ask whether it is useful. The test is concrete: after one reading, is your description of the matter more specific than before? If you started with only “I am torn” and, after reading the cards, can say “what I am torn about is not whether to leave, it is that I am afraid leaving will confirm I cannot do this” — then it was accurate.
In reverse, any use of tarot that claims “one hundred percent accurate”, that it can “change your luck” or “ward off bad fortune” deserves suspicion. That is not tarot, it is a sales line, and it is one you are running on yourself.
