some gooey parabola-like shape somewhere in their brain
This does not seem obvious to me. The ability to make a rock go roughly where you want does not translate to the ability to accurately draw its trajectory on paper. Granting that there is clearly some part of the brain that does calculations (which may not involve parabolas because of the air resistance, as noted in earlier comments) you have no introspective access to those calculations. Besides which, they might well be wrong for cannonballs; humans do not throw half-ton weights at a good fraction of the speed of sound.
Yeah, I’ve re-addressed that line of reasoning. I became briefly fascinated by how a human brain could plot a quadratic shape, until I discovered the Gaze Heuristic.
I’m still convinced there’s some sort of parabola heuristic though, simply through my own experience of juggling, which doesn’t seem to conform to the gaze heuristic. I also cite the popularity of Angry Birds as weak but hilarious evidence.
Even later in replying, but oh well.
