Do schoolteachers cheat to meet high-stakes testing standards? Is sumo wrestling a corrupt sport? What caused crime rates in the United States to plunge in the 1990s?

With the help of data in the form of schoolchildren’s test scores, sumo match records, abortion history, or crime rates, the author has come to various shocking conclusions and unmasked the real world behind the veil.
