content: Is Jared Diamond tendentious? Of course. Is he as bad as Stephen Jay Gould? No. There's a whiff of Lysenkoism (a term I just learned and like...it means using science to justify some ideological aim) to the book, but there is much that is fruitful and edifying. This should be read by everyone, left, right, or center. Just be aware that this is a theoretical work, relying on a great deal of circumstantial evidence, and that Diamond wants nothing to do with any explanation that factors in physiological differences between groups of human beings...especially regarding innate intelligence.
