People seem to forget most of what they read, and they mostly don’t notice

It seems that most people can remember only a few high-level details of a book weeks later—if that. A typical reader might spend hours finishing some serious non-fiction—then maybe it comes up at a dinner party, and they find you can remember like three sentences. Basically no detailed recall. Barely the gist!

What’s more: people seem surprised when this happens. They seem to consistently overestimate how much they’re absorbing from a book.

I can’t find real empirical data on this question, so this is largely an anecdotal claim. Some light evidence in suggested by Amlund et al, who showed <50% free recall minutes later, even when readers knew it was a test.

This observation is unfortunate for many reasons, but among them: Conceptual understanding is unlikely without detailed knowledge of fundamentals and Complex ideas may be hard to learn in part because their components overflow working memory.
