content: While I urged myself on to finish the book, Diamond lost much of his credibility in his prologue. After making impassioned statements against "racist" assertions of ethincally based differential intelligence, he goes and says New Guineans are more intelligent than wetern Europeans. I am a south-west Asian ethincally so my reaction to that was not a defensive one. He fell headlong into the trap of guilt-driven Western reverse-prejudice. I can't beleive non of his editors insisted he take that piece out.
