I have personally observed over and over that there are certain classes of mental mistake that you simply CANNOT reliably correct in non-interactive media, because the person making the mistake simply can't tell they're making the mistake unless you point out an example of it in their own behavior or thinking.
I know I don't really get a given cognitive bias unless I can think of an example of me doing it and feel stupid at the realisation. (I have previously generalised from myself on this point, but I'll try to refrain from that.)
LW doesn't seem to have a discussion of the article Epiphany Addiction, by Chris at succeedsocially. First paragraph:
I like that article because it describes a dangerous failure mode of smart people. One example was the self-help blog of Phillip Eby (pjeby), where each new post seemed to bring new amazing insights, and after a while you became jaded. An even better, though controversial, example could be Eliezer's Sequences, if you view them as a series of epiphanies about AI research that didn't lead to much tangible progress. (Please don't make that statement the sole focus of discussion!)
The underlying problem seems to be that people get a rush of power from neat-sounding realizations, and mistake that feeling for actual power. I don't know any good remedy for that, but being aware of the problem could help.
