In Michael Lewis's book "The Undoing Project," the author presents a perspective on the uncertainty inherent in several global issues. He notes that many intriguing questions, such as predicting oil prices a decade into the future, often defy definitive answers. The acknowledgment of such uncertainty does not equate to inactivity; rather, it encourages a nuanced approach to understanding and estimating these unpredictable situations.

The author emphasizes the importance of framing answers in probabilistic terms. This approach recognizes the complexity and variability of real-world phenomena while allowing for informed speculation. Thus, while certainty may be unachievable, engaging with these uncertainties thoughtfully can still lead to useful insights and better decision-making.
