For myself I find this point is poorly understood by most self-identified rationalists, and I think most people reading the sequences come out of them as positivists because Eliezer didn’t hammer the point home hard enough and positivism is the default within the wider community of rationality-aligned folks (e.g. STEM folks).
Maybe so, but I can’t help noticing that whenever I try to think of concrete examples about what postrationality implies in practice, I always end up with examples that you could just as well justify using the standard rationalist epistemology. E.g. all my examples in this comment section. So while I certainly agree that the postrationalist epistemology is different from the standard rationalist one, I’m having difficulties thinking of any specific actions or predictions that you would really need the postrationalist epistemology to justify. Something like the criterion of truth is a subtle point which a lot of people don’t seem to get, yes, but it also feels like one which doesn’t make any practical difference whether you get it or not. And theoretical points which people can disagree a lot about despite not making any practical difference are almost the prototypical example of tribal labels. John Tooby:
The more biased away from neutral truth, the better the communication functions to affirm coalitional identity, generating polarization in excess of actual policy disagreements. Communications of practical and functional truths are generally useless as differential signals, because any honest person might say them regardless of coalitional loyalty. In contrast, unusual, exaggerated beliefs—such as supernatural beliefs (e.g., god is three persons but also one person), alarmism, conspiracies, or hyperbolic comparisons—are unlikely to be said except as expressive of identity, because there is no external reality to motivate nonmembers to speak absurdities.
