The element that I’d call clearly meta-rational is understanding that rationality is not one well-defined thing but a bag of tricks that are more-or-less applicable in different situations. It’s meta-rational in that it’s about how rationality works and is used in practice.
What’s different is that it treats decision theory as a tool that may or may not be useful depending on the situation, rather than as The Correct Way Of Being Rational Even If We Can’t Specify Exactly How To Use It.

In general I think that when you can reduce some area of your life to a fairly tractable quantification that yields a reliable definite answer you should do so. My model of the world is that there is so much complexity hidden everywhere that this heuristic is of marginal use.
