I was contrasting abductive reasoning to deductive and inductive reasoning, something that has happened around here before.  The point was that one could not deduce Born's rule from accepted premises, not induce it from prior examples.  Though maybe it is an induction from prior experience with photon wave functions.

This looks to be a nice presentation of the Bethe ansatz, https://arxiv.org/pdf/cond-mat/9809162.pdf, which appears to be an inspired selection of basis functions for solving a 1-d spin glass.  So, no, Born's rule was not an ansatz, but Bethe's ansatz might be an abduction.

and, is an ansatz, more or less, a formalized metaphor?
