The Halo Effect

1. IDEA 1

   Success creates a glowing halo

   Rosenzweig argues that when companies perform well, observers tend to praise everything about them, such as their culture and leadership. When performance falls, the same features are suddenly criticised. This halo effect distorts business analysis.

2. IDEA 2

   Stories followed results

   Rosenzweig describes companies like Cisco and ABB, praised during success and criticised after decline. Their practices had not changed much; perceptions had. Rosenzweig says people judge a firm's methods by its results, so the same habits look wise or foolish depending on profits.

3. IDEA 3

   Business books often mislead

   Rosenzweig argues that many popular business studies rely on data shaped by the halo effect. Their conclusions about what causes success may be wrong. For example, managers may praise a company's culture after it makes profits because they are influenced by those profits.
