In "The Undoing Project," Michael Lewis explores how human decisions are often influenced by the concept of chance. He likens life to a casino, where every choice we make resembles a gamble. People frequently assess situations based on perceived similarities, which can dictate their judgments and outcomes.

The narrative delves into the cognitive biases that shape our understanding of risk and probability. By illustrating how our minds operate like a game of chance, Lewis emphasizes the importance of recognizing these patterns in our decision-making processes. Ultimately, it reflects on the interplay between friendship and intellectual discovery, reshaping our perspectives on human behavior.
