High Quality Content by WIKIPEDIA articles! The Halo Effect is a 2007 book by business academic Phil Rosenzweig that criticizes pseudoscientific tendencies in the explanation of business performance. As well as many business magazines and newspapers, it targets specific books (those that offer secrets of guaranteed business success) and academic research published by business schools. It outlines nine "delusions": mistakes of reasoning that undermine these recipes for business success. In light of these mistakes, Rosenzweig argues, much of business writing is what Richard Feynman called "cargo cult science", having the superficial trappings of science but operating at the level of story-telling. The book also considers some more scientific business research, whose conclusions are more rigorous but do not promise a simple recipe for success. The subtitle of the 2007 US edition is "and the eight other business delusions that deceive managers" while that of the 2008 UK edition is "How Managers Let Themselves Be Deceived".
