      I learned from this a new way of thinking about thinking, “cognitive decoupling,” and its role in disagreements.https://twitter.com/everytstudies/status/989544002511949825 …

      Since @everytstudies’ post is long, and has prompted some interesting discussion: here is Sarah Constantin’s explanation of “cognitive decoupling.” It’s an aspect of systematic rationality, focusing on limiting inference. https://srconstantin.wordpress.com/2014/06/09/do-rationalists-exist/ …pic.twitter.com/1QUz9ImPoI

      Systematic rationality only works if you do limit inference, because nothing is really truly true. If you take true-enough-for-this-context as “truly true,” you infer way too much. If you take it as “false,” you can’t infer anything.

      David Chapman Retweeted John Nerst

      Effective use of rational inference requires “circumscription assumptions,” which say what sorts of considerations count as relevant in a particular situation, for particular purposes.https://twitter.com/everytstudies/status/989602997264142336 …

      What it means for separating or not separating scientific findings from political implications is somewhat captured by this excerpt: pic.twitter.com/hKB4kGaOx9

      The term “circumscription” was introduced by John McCarthy as a key move in the logicist program of AI (which he founded). You can’t use logic in the real world without it or something equivalent. https://en.wikipedia.org/wiki/Circumscription_(logic) …

      Interesting point that applying logic to the real world requires tight limits or it stops working. Seems obviously correct but I never thought of it in exactly that way.

      The _Hard Truths_ book I live-tweeted a couple days ago is largely about this point. The first 3-4 chapters are great; it bogs down in the technicalities of analytic metaphysics after that.

          Has been on hold since October, due to family responsibilities. In the last week I’ve just started to get enough free time to start doing some background reading. Will be another couple months before I can work on it in earnest, at a guess.
