Episode notes

Economist Dick Thaler discovered that people in the real world do not always make decisions rationally, contrary to economic models. These departures from rationality could be systematic rather than random, leading to predictable errors. Thaler's excitement arose from the intersection of his work on economic decision-making and Kahneman and Tversky's research on cognitive biases, providing a groundbreaking insight into non-rational decision-making processes.

The notion of merging psychology with economics initially faced staunch skepticism, with errors perceived as random rather than systematic. However, everything changed when psychologists Daniel Kahneman and Amos Tversky joined forces, armed with groundbreaking ideas about human decision-making. Their meticulous research not only introduced a fresh perspective on understanding people’s choices but also ignited the flames of Behavioral Economics. Through collaboration with other influential figures in the field, including Richard Thaler, their work spearheaded a transformative movement that challenged conventional economic assumptions, propelled novel ideas forward, and seamlessly integrated psychological theories into economic theory and practice.
