Real interesting, but entirely overlooks the category of Conservative Riverians.
Those with the Riverian cognitive and personality clusters (inclined to quantify), but recognize its limitations:
The constrained vision puts a premium on “systematic rationality.” This simply refers to the collective experience and wisdom contained in long-evolved social processes and systems. Since the constrained vision doesn’t think that any one person or small group of individuals can really become smart enough to dictate decisions for everyone else, the combined knowledge held in culture, tradition, legal precedent, and other structures is superior. This knowledge gets created by a survival of the fittest society. If our society has survived thus far, that means it has beaten out other competing societies that have failed. Mankind will probably not be able to understand everything about the system that makes it good, and as such should simply trust its lasting success and view admonitions for significant change with suspicion.

Doesn't seem to recognize that if the Village is "distinctly left-of-center" and the EA and Rationalist wings of Riverians are 13:1 and 2.6:1 registered Democrats vs Republicans (respectively), he's missing most conservatives. Who, dismissive of intentions in favor of outcomes and assume trade offs over solutions, etc., reside most naturally in the River.
Even mentions evolutionary psychology and Chesterton's Fence, but doesn't follow how they would influence a Riverian.
