The main argument or claim made by the author in Freakonomics is that economics is essentially the study of incentives and how they influence human behavior. The authors, Steven Levitt and Stephen Dubner, use economic theories to analyze and explain various social phenomena, such as cheating in sumo wrestling or the structure of drug gangs. They argue that by understanding the incentives at play, one can predict and explain seemingly unrelated social behaviors and trends. They also challenge conventional wisdom and encourage readers to look at things from a different perspective.

The main subject or topic that the authors Steven Levitt and Stephen Dubner talk about is the application of economic theories to analyze various social issues.

The authors use stories and case studies to illustrate that economics is fundamentally about studying human behavior and how people achieve their desires.
