From David Robson's book, examines the concept of the "intelligence trap," arguing that high general intelligence (IQ) and expertise do not necessarily equate to rational or wise decision-making, and can, in fact, make people more susceptible to cognitive errors like motivated reasoning and the myside bias. It highlights examples of highly intelligent individuals, including Nobel laureates and historical figures, who held irrational beliefs or made catastrophic mistakes in their personal or professional lives. The book contrasts traditional intelligence with skills essential for evidence-based wisdom, such as intellectual humility, open-mindedness, and emotional regulation, suggesting these traits are crucial for overcoming common cognitive blind spots. Furthermore, the author explores techniques to foster wiser thinking, such as self-distancing and critical thinking skills, and discusses how factors like organizational culture and group dynamics can either amplify or mitigate collective stupidity.
