Professor Jeffrey Pfeffer said that Greene's so-called laws are based on isolated examples, and not on solid research. "Kirkus Reviews" said Greene offers no evidence to support his world view, Greene's laws contradict each other, and the book is "simply nonsense". "Newsweek" also points out ways the laws contradict each other and says "Intending the opposite, Greene has actually produced one of the best arguments since the New Testament for humility and obscurity." "Director" magazine notes "some of Greene's 'laws' seem contradictory" and the work is "plodding and didactic".
