 One of the best known “light duty” versions of TT proposes that FP should be understood as nothing more than an intentional stance or heuristic we employ for quick and dirty predictions of the behavior of a wide variety of systems (Dennett 1985, 1987). FP ascriptions are, on the intentional stance view, irredeemably indeterminate. As such, we have no grounds for taking FP attributions ontologically seriously above and beyond the limited practical leverage they give us in enabling us to make such predictions and explanations.
