Query: Fun, but unconvincing and shallow

Authors give an account of important findings of evolutionary psychology, as a way to improve our lives. But covering so many topics in just 250 pages must lead to trivializing science in truly barbarian style. If you are unconvinced of validity of evolutionary approach to understanding human nature: keep away, this book will only outrage you. If you are interested, or are an 'intelectually sophisticated' person, take Buss' 'Evolutionary psychology', 'Adapted mind' or 'Evolution of desire' for easier approach. Those who know already some ev-psych, will by simply bored, as they will find almost nothing new in 'mean genes', nothing that they couldn't think of themselves. Only truly open minded readers, who haven't got in touch with the field, and want to have some fun would really love that book.
