You're abusing the term "subjective probabilities" here, perhaps
willfully.  Valid use of the term pertains to estimating your
subjective uncertainty about the actual state of some aspect of
reality. If your objective is truly "about how wild-type psychology
leads one..." then your focus should be on the psychology of
heuristics and biases, definitely NOT philosophy.

The difference between the camps is not between obvious right answers,
but about the relative importance assigned to max entropy modeling
versus defending the illusion of an essential self.

You're right.  It **could** be true.
