The CFAR handbook is good stuff that gets at important aspects of rationality, but I don’t think it counts either as something that core LessWrong userbase has mostly read, or is nearly as much the stuff that gets used regularly in conversations here. Among other things, the PDF of it wasn’t generally available until 2020, and a nicely formatted sequence until a year ago.
