Their main aim is to engage and teach the common person versatile concepts of economics in a harmless manner. In doing so, they take into account all kinds of people who might read it, including drug dealers. This way, a drug dealer could read facts about his industry and digest the data about him, without feeling offended or attacked by the words chosen by the perpetrators. Levitt and Dubner make their book a global read because anyone can read it, regardless of their background, without being offended while doing so. The authors use contrast in a fluent conversational style. The two talk about how today's society is doing its best to find ways to reduce the crime rate. They then add that "some people would say we're not doing a very good job" (18), then immediately refute this comment by stating: "but in the long run, that's clearly not true." (18). The authors are extremely intelligent in their writing style because they show readers the opinions of some and then prove it to be factually incorrect. They also provide evidence as to why they, as economists, are right in a graph.
