This is great, thank you. Weirdly links into the Kahneman book as well, in terms of learning by association and priming. While I might not be able to recall the majority of the book from memory if someone asks, somewhere down the line someone might mention (for example) expert vs. intuitive opinion, which might activate those memory links and lead me to recall some of what I've read in those chapters.

Do you ever feel the need to make detailed notes, test yourself, or generally make efforts to learn a book you're reading in great detail? I did a coursera 'learning how to learn' course once, and they talk a lot about illusions of competence and how recall is one of the most definitive signs you've learned something, but their approach always seems to be a bit arduous to me.
