The Halo Effect

With two new chapters and a new preface, the award-winning book The Halo Effect continues to unmask the delusions found in the corporate world and provides a sharp understanding of what drives business success and failure. Too many of today’s most prominent management gurus make steel-clad guarantees based on claims of irrefutable research, promising to reveal the secrets of why one company fails and another succeeds, and how you can become the latter. Combining equal measures of solemn-faced hype and a wide range of popular business delusions, statistical and otherwise, these self-styled experts cloud our ability to think critically about the nature of success. Central among these delusions is the Halo Effect—the tendency to focus on the high financial performance of a successful company and then spread its golden glow to all its attributes—clear strategy, strong values, brilliant leadership, and outstanding execution. But should the same company’s sales head south, the very same attributes are universally derided—suddenly the strategy was wrong, the culture was complacent, and the leader became arrogant. The Halo Effect not only identifies these delusions that keep us from understanding business performance, but also suggests a more accurate way to think about leading a company. This approach—focusing on strategic choice and execution, while recognizing the inherent riskiness of both—clarifies the priorities that managers face. Brilliant and unconventional, irreverent and witty, The Halo Effect is essential reading for anyone wanting to separate fact from fiction in the world of business. The Delusion of Rigorous Research: Many bestselling authors praise themselves for the vast amount of data they have gathered, but forget that if the data aren't valid, it doesn't matter how much was gathered or how sophisticated the research methods appear to be. They trick the reader by substituting sizzle for substance. The Delusion of Single Explanations: Many studies show that a particular factor, such as corporate culture or social responsibility or customer focus, leads to improved performance. But since many of these factors are highly correlated, the effect of each one is usually less than suggested. In what promises to be a landmark book, The Halo Effect replaces mistaken thinking with a sharper understanding of what drives business success and failure. The Halo Effect is a guide for the thinking manager, a way to detect errors in business research and to reach a clearer understanding of what drives business success and failure. Skeptical, brilliant, iconoclastic, and mercifully free of business jargon, Rosenzweig's book is nevertheless dead serious, making his arguments about important issues in an unsparing and direct way that will appeal to a broad business audience. For managers who want to separate fact from fiction in the world of business, The Halo Effect is essential reading -- witty, often funny, and sharply argued, it's an antidote to so much of the conventional thinking that clutters business bookshelves.
