How did a brilliant physics professor end up smuggling 2 kilograms of cocaine across the Argentine border? Why do doctors misdiagnose 10 to 15% of their patients? Why do Nobel laureates spread false news? The assumption that smarter people are less prone to mistakes is incorrect. Greater education and specialization can often reinforce our errors, making us blind to our biases. This is the "intelligence trap". Based on the latest behavioral science and historical examples from Socrates to Benjamin Franklin, David Robson shows how to apply our intelligence more wisely. That is, to identify biases and enhance our "rationality index", to recognize and regulate our emotions, to adjust our intuition, and to think more flexibly about seemingly dead-end problems. The 21st century brings us complex problems that require a wiser approach to thinking. Whether you are a NASA scientist or a school student, "The Intelligence Trap" offers a new thinking tool to fully harness your potential.
