This is a good observation. It still leaves open the question of helping (or self-help advise) for people of sufficient intelligence to perceive that LW-style "rationality" is correct in some sense, but cannot quite put it together themselves into a useful framework from a bunch of blog posts :). I do think CFAR has a role in this, Stanford's Ron Howard took it all the way to (non gifted-) high school level:

The two things this can accomplish is to create better "non-weird" cultural memes than society provides out of the box, and in the long term perhaps establishing priesthood of rationality where people can escalate important/complicated decisions to more expert authorities.
