2.0

I learned a few things of interest and I'm keen to give non-fiction more of a chance specifically due to that educational purpose.

However, I thought about giving up on this book on multiple occasions, including after battling to 60% read. This book would greatly benefit from a slashing copy edit to shorten it significantly and tighten up the narrative.

The author often repeats himself, describing the results of a study and then repeating those findings as now fact. He also spends a lot of time writing "more on that later" or "which we covered in chapter x" which is clumsy. If you need wayfinding statements, it's more proof that you need to tighten the content.

There are also exclamation points. A lot of them. They just shouldn't be in non-fiction. If the content is actually fascinating, you shouldn't need to force feed it to your readers as (!) Wow, isn't this amazing?!
