If it’s worth saying, but not worth its own post, you can put it here.
Also, if you are new to LessWrong and want to introduce yourself, this is the place to do it. Personal stories, anecdotes, or just general comments on how you found us and what you hope to get from the site and community are welcome. If you want to explore the community more, I recommend reading the Library, checking recent Curated posts, and seeing if there are any meetups in your area.
The Open Thread sequence is here.
I can offer an explanation that might fit. Rationalists tend toward expertise mode thinking (expert from the torbert action logic framework). Behaviour like reading the book is in line with the expert behaviour.
Cfar techniques and related in-person methods are not always about being the expert, they are about doing the best thing. Being a better expert is not always the same as being the better munchkin, the better person or the person who can step out of their knowledge beliefs.
In theory, the expert thing is the best thing. In theory there's no difference between theory and practice, in practice, there's a big difference between theory and practice.
Having said that, I've never done cfar, and I teach workshops monthly in Sydney and I think they are wrong to discourage sharing of their resources. As the same time I accept the idea of intellectual property being protected even if that's not the case they are claiming.
