Business Book Award: Thomas Homer-Dixon

Thomas Homer-Dixon received the National Business Book Award last night for The Upside of Down, his argument that things today are, well, complicated. Well deserved -- H-D writes vigorous prose on complicated matters. But this Business Book Award is one I don't understand. Some years their lists focus on narrow, technical works on macro-economic policy or management science; another year it's all history or pop sociology. Charlotte Gray's Alexander Graham Bell bio is a terrific book -- but a business book? Bill Davis seems to be on the jury every year, but the jury's sense of what constitutes a business book seems to jump all over.
