Every year, a new crop of business books promises to reveal the secrets of high performance. They point to companies like ABB, Cisco, Enron, or Nokia and explain exactly what made them great. The formula seems clear. Follow these steps, adopt these habits, embrace these values, and your company can achieve lasting success too. Then the story changes. ABB nearly collapsed under a mountain of debt. Cisco's stock plummeted. Enron became synonymous with fraud. Nokia lost its dominance in mobile phones. The same business press that celebrated these companies as visionary later described them as arrogant, complacent, and strategically confused.

Its people seem talented. When performance declines, the same attributes get reinterpreted. The visionary leader is now stubborn. The strong culture is now insular. The brilliant strategy was actually reckless. This bias would be manageable if it only affected casual observers. But Rosenzweig shows that it contaminates even the most rigorous-sounding research. When business professors and consultants gather data about company culture, leadership, or strategy, they often collect…
