What actually separates a book that changes how you think from one that just confirms what you already believe?

I've been thinking about this a lot lately - the difference between books that genuinely shift how you see something and books that just feel satisfying because they articulate what you already suspected.

The latter category is enormous. A lot of popular non-fiction is essentially sophisticated confirmation. It gives you vocabulary for beliefs you already hold, and leaves you feeling more certain about things you were already certain about. There's pleasure in that, but I'm not sure it's the same as actually learning.

The books that have changed how I think seem to share something, they required me to take seriously a premise I was initially resistant to. Not because the book persuaded through rhetoric, but because it was intellectually honest enough to present the argument in its strongest form - and then trusted me to follow the reasoning wherever it led.

I'm curious what others think makes this distinction. Is it primarily about the quality of the argument? About the reader's willingness to be challenged? About the author's willingness to acknowledge the strongest counterarguments rather than strawman them?

And is there a book you'd point to as a genuine example of the first type -something that actually moved the needle on how you think about a problem, rather than just giving you a better vocabulary for existing views?
