When I figured out many years ago that you could read one good textbook about a subject and know more than 50% of “experts” in the actual field and 99.999% of laypeople, I was flabbergasted. Most people — again, even the experts — simply have not done the work.

If you read and understand ~3 books in a field of study, you then know more than ~95% of experts and 99.9999999% of laypeople. I’ve done this in roughly 100 fields, though some I need to refresh on since it’s been two decades.

(I’ve read the Janeway Immunobiology book, by the way. It’s very good! Basic Immunology: Functions and Disorders of the Immune System by Abbas et al. is also great.)
