Levitt and Dubner's purpose in Freakonomics is to convey the message that your first judgment based off of common sense is rarely right. The authors go in depth about exploring “The hidden side of everything”. Freakonomics provides many statistics and facts showing the inner workings of things in our everyday lives, and why these things work as they do. Levitt’s underlying belief is that, “The modern day world, despite a surfeit of obfuscation, complication, and downright deceit, is not impenetrable, is not unknowable, and- if the right questions are asked- is even more intriguing than we think. All it takes is a new way of looking”(Page xxv of Freakonomics). Levitt not only researched things such as this but this is the way he believes, that with a different perspective a new world can be revealed. Levitt explores why a persons reasoning can be wrong on a topic so simple, such as criminal rates. “Cities with a lot of murders also tend to have a lot of police officers. Consider now the police/murder correlation in a pair of real cities. Denver and Washington, D.C., have about the same population- but Washington has nearly three times as many police as Denver, and it also has eight times the number of murders” (Page 9 of Freakonomics). This fact causes readers to rethink their assumption that the more police officers there are, the less crime there would be; Which is very untrue.
