Negative Positive
Title: Not Recommended
Review: Well written and well researched books can still be seriously flawed, of course, and I believe this is one example. Mr. Diamond tips his hand fairly early in the book by taking pains to explain that there is no scientific evidence of genetic variations in intelligence and that this idea came about through Eurocentrism. He then states that his aboriginal friends of New Guinea are obviously more intelligent than white Europeans and wonders how the two cultures developed so differently. This contradiction and Mr. Diamond's pretty obvious biases made it very difficult for me to take his answers to this very interesting question seriously.
Is the review positive or negative?
