I would no take this you wrote as an argument against ISF(p) as Si is not about “efficiently navigating the present” per se, and general absent-mindedness can be argued to be a derivative of Te PoLR, with Te generally being resented by ISFPs for being a force that comes between them and ‘real thinking’ (which to them is more enjoyable…something more Ti) . These Te faux passes can appear to them as happening because “they spend too mich time in their own head” (among others).
