In "The Undoing Project," Michael Lewis explores the complexities of human behavior and decision-making, highlighting the challenges people face when attempting to create positive change. He suggests that while the intention to improve the world is noble, demonstrating the effectiveness of those efforts often proves to be more difficult than the act of trying itself. This raises questions about accountability and the metrics we use to assess change.

The quote emphasizes that the process of making a difference may be more straightforward than justifying or evidencing that impact. It reflects on the nuances of social change, where actions might speak louder than results. Ultimately, Lewis invites readers to consider how we appraise both actions and their outcomes in the context of personal and collective progress.
