Short storyline
The authors attempt to demonstrate the power of data mining. Many of their results emerge from Levitt's analysis of various databases, and asking the right questions. Authors posit that various incentives encourage teachers to cheat by assisting their students with multiple-choice high-stakes tests. Such cheating in the Chicago school system is inferred from detailed analysis of students' answers to multiple choice questions. But first Levitt asks, "What would the pattern of answers look like if the teacher cheated?" The simple answer: difficult questions at the end of a section will be more correct than easy ones at the beginning.
