I’d just like to note that as with most of the rationality material in Eliezer’s sequences, the position in this post is a pretty common mainstream position among cognitive scientists. E.g. here is Jonathan Baron on page 61 of his popular textbook Thinking and Deciding:
the best kind of thinking, which we shall call rational thinking, is whatever kind of thinking best helps people achieve their goals. If it should turn out that following the rules of formal logic leads to eternal happiness, then it is rational thinking to follow the laws of logic (assuming that we all want eternal happiness). If it should turn out, on the other hand, that carefully violating the laws of logic at every turn leads to eternal happiness, then it is these violations that we shall call rational.
This view is quoted and endorsed in, for example, Stanovich 2010, p. 3.
