Summary
Robert J. Sternberg’s book, Why Smart People Can Be So Stupid , which examines why individuals with high intellectual capacity often commit breathtaking errors in judgment. The authors argue that traditional measures like IQ and "book smarts" fail to account for real-world failures, such as those seen in major political scandals or professional misconduct. The collection distinguishes between intelligence and wisdom , suggesting that "stupidity" is often a failure of self-regulation , rational thinking, or the inability to adapt to changing environments. Carol Dweck explores how a belief in fixed intelligence causes people to avoid challenges, while Richard Wagner analyzes managerial incompetence and the importance of tacit knowledge . Ultimately, the sources suggest that smart people act foolishly when they prioritize looking intelligent over the continuous process of learning and objective reasoning.
