I mean I can see it. Books are just a way to transmit one’s thoughts and experiences to other people. So it’s no different to being exposed to someone with a different viewpoint. Common sense isn’t common or innate, it’s tribal knowledge.

There’s that XKCD about someone learning something new that was just thought to be something everyone knew.

Also you don’t know what you don’t know.

Agree though — coaching and persuasion are a huge part which is why I think a lot of these books seem ‘fluffy’ if all you’re wanting is a collection of facts.
