I've only read one of those books: Guns, Germs and Steel, and I learned and retained a _lot_ from it. Now, whether what I learned and retained was accurate and worth retaining is a subject of great dispute - there are a lot of people who really hate this book because they disagree with it, but that's not the author of this post's point.
