Do Nothing: How to Break Away from Overworking, Overdoing, and Underliving by Celeste Headlee. Where Kahneman provides the cognitive science account of why extended hours degrade the quality of thinking, Headlee provides the historical, anthropological, and psychological account of how the assumption that more hours produces more output came to dominate working culture despite the evidence against it. Her research-grounded account of the Pencavel hours-output findings, the historical evidence for shorter productive working patterns across pre-industrial and non-Western cultures, and the psychological evidence that genuine recovery is not a productivity cost but a structural requirement of sustainable high output makes the complementary case from the outside in: not only does the cognitive science predict the diminishing returns, but the historical and cultural evidence shows that the working patterns now treated as normal are both recent and substantially evidence-free. Together, Kahneman and Headlee provide the cognitive mechanism and the cultural context for a research-grounded reassessment of the hours-output assumption.
