In "The Fifth Risk," Michael Lewis expresses a critical concern regarding how science is often misapplied to endorse various policies. He highlights the potential dangers that arise when data and scientific findings are manipulated to fit political agendas rather than serving the public good. This misuse undermines trust in science and can have serious consequences for decision-making processes.

Lewis suggests that a lack of proper understanding and respect for scientific principles can lead to ineffective or harmful policies. His work warns of the risks associated with ignoring factual evidence, emphasizing the importance of integrity in the application of science to guide policy decisions. Ultimately, he advocates for a thoughtful and responsible approach to incorporating scientific insights in governance.
