I've spent so much time in the cogsci literature that I know the LW approach to rationality is basically the mainstream cogsci approach to rationality (plus some extra stuff about, e.g., language), but... do other people not know this? Do people one step removed from LessWrong — say, in the 'atheist' and 'skeptic' communities — not know this? If this is causing credibility problems in our broader community, it'd be relatively easy to show people that Less Wrong is not, in fact, a "fringe" approach to rationality.
For example, here's Oaksford & Chater in the second chapter to the (excellent) new Oxford Handbook of Thinking and Reasoning, the one on normative systems of rationality:
Is it meaningful to attempt to develop a general theory of rationality at all? We might tentatively suggest that it is a prima facie sign of irrationality to believe in alien abduction, or to will a sports team to win in order to increase their chance of victory. But these views or actions might be entirely rational, given suitably nonstandard background beliefs about other alien activity and the general efficacy of psychic powers. Irrationality may, though, be ascribed if there is a clash between a particular belief or behavior and such background assumptions. Thus, a thorough-going physicalist may, perhaps, be accused of irrationality if she simultaneously believes in psychic powers. A theory of rationality cannot, therefore, be viewed as clarifying either what people should believe or how people should act—but it can determine whether beliefs and behaviors are compatible. Similarly, a theory of rational choice cannot determine whether it is rational to smoke or to exercise daily; but it might clarify whether a particular choice is compatible with other beliefs and choices.
From this viewpoint, normative theories can be viewed as clarifying conditions of consistency… Logic can be viewed as studying the notion of consistency over beliefs. Probability… studies consistency over degrees of belief. Rational choice theory studies the consistency of beliefs and values with choices.
They go on to clarify that by probability they mean Bayesian probability theory, and by rational choice theory they mean Bayesian decision theory. You'll get the same account in the textbooks on the cogsci of rationality, e.g. Thinking and Deciding or Rational Choice in an Uncertain World.
Vladimir_M, what makes you think that elite universities have the desire and money/power to proselytize their "output"? I mean, you surely know about the trouble they are having trying to win the propaganda fight against creationism, and against global warming denial. And then there's anti-vaccination and the moon landing conspiracy.
In fact the statement that I quoted seems to so obviously deserve the answer "yes, they are unable to spread the word" that I wonder whether I am missing something.
Perhaps you were thinking that elite universities only need to spread the word amongst, say, the smartest 10% of the country for it to matter. But even in that demographic, I think you will find that few people know about this stuff. Perhaps with the release of books such as Predictably Irrational things have improved. But still, such books seem somewhat inadequate since they don't aim to cleanly teach rationality, rather they aim to give a few cute rationality-flavoured anecdotes. If someone reads Predictably Irrational I doubt that they would be able to perform a solid analysis of the Allais Paradox (because Predictably Irrational doesn't teach decision theory in a formal way) and I doubt that their calibration would improve (because Predictably Irrational doesn't make them play calibration games).
There are very, very few people employed at universities whose job description is "make the public understand science". As far as I am aware there is literally no-one in the world whose job title is "make the public understand cognitive-biases-style rationality"
Mencius Moldbug has convincingly argued on his blog, that intellectual fashion among the ruling class follows intellectual fashion on Harvard by an offset of about one generation. A generation after that the judicial and journalist class exiles any opposition to such thought from public discourse and most educated people move significantly towards it. A generation after that through public schools and the by now decades long e... (read more)
