Summarize how Levitt and Dubner logically support their argument that cheating exists when there is high incentive, but that the majority of people are honest.

Answer:

In the introduction to Freakonomics, Levitt and Dubner claim that economics is primarily the study of incentives. They provide evidence from sumo wrestling to show how athletes may cheat when incentives for winning are high, and they use the anecdote of the bagel man to demonstrate that people are generally honest even without direct supervision. While addressing counterarguments about the predictability of human nature, they conclude that analyzing data and incentives reveals the hidden side of the contemporary world.
