If Rationality is Winning, or perhaps more explicitly Making The Decisions That Best Accomplish Whatever Your Goals Happen to Be, then Rationality is so large that it swallows everything. Like anything else, spergy LW-style rationality is a small part of this, but it seems to me that anything which one can meaningfully discuss is going to be one such small portion. One could of course discuss Winning In General at a sufficiently high level of abstraction, but then you'd be discussing spergy LW stuff by definition - decision theory, utility, and so on.

If businessfolk are rather rational at running businesses, but no rational than anyone else about religion, or if people who have become experts on spergy LW stuff are no more winningful about their relationships, &c. &c. this (to my mind) brings into question the degree to which a General Rationality-as-Winningness skill exists. You acknowledge the distinction between explicit and tacit rationality, but do you expect successful entrepreneurs to be relatively more successful in their marital life? When you say you want to teach tacit rationality, do you mean something distinct from Teaching People How To Do Things Good?
