Everyone knows that.

I think Richard was trying for a reframing of the example, as a way
of demonstrating how a quick&dirty fast&frugal catch-as-catch-can
structure like a typical brain/body response actually operates, in
the list's context of seeking insight into machine analogues of
cognition, evaluation and response.

It seems to me quite consonant with the (experimentally demonstrable)
Roschean model of type representation. Eliezer noted "the standard
experimental result *and its standard interpretation*: subjects
substitute judgment of representativeness for judgment of
probability... Judgment by representativeness, like judgment by
availability, is a heuristic that can often produce useful results -
some even say a fast and frugal heuristic - but the heuristic also
produces systematic biases, which are what reveal to us that the
heuristic exists in the first place, and what pin[s] down how the
heuristic must be working to produce those specific biases." Yes,
yes, yes, nor did Richard dispute the fallibility *for some rather
contrived purposes* of templated heuristics that are effective *for
other daily purposes*. So why all the bad temper and foot-stamping?
