What Do Schoolteachers and Sumo Wrestlers Have in Common?  Cheating, like almost everything else that involves incentives, can be predicted Research processes made the author identify a number of Chicago public school teachers who cheated by helping their students cheat. He analyzed standardized test answer patterns and identified suspicious blocks of correct answers, also comparing test scores to students’ past academic performance.  Also research projects involved the analysis of the scores and bout records of Japan’s elite-level sumo wrestlers. He analyzed and compared the performances of the wrestlers in matches with vastly different stakes and potential consequences. The story of an entrepreneur who sold bagels using the honor system to office workers in Washington,  D.C. concludes the chapter.  The owner kept detailed financial records, and by analyzing them, author  was able to discern a number of remarkably consistent patterns in the behavior of those who took bagels without paying for them.
How is the Ku Klux Klan like a Group of Real-Estate Agents?  information asymmetry is one of the most powerful economic tools  Stetson Kennedy helped cripple the racist Ku Klux Klan during the era of world war –II simply by widely disseminating their secrets. He systematically documented the secret rituals and codes of the organization and supplied the records to Hollywood writers, who used the information on radio. Children across the United States imitated the shows in their schoolyard games, and gradually, the mystery, grandeur, and influence of the group were profoundly diminished.  Analyzing data about real estate agents common practices when they are selling their own houses, shows that not always do they have their clients’ best interests at heart.
Why Do Drug Dealers Still Live with Their Moms?  Because most of them don't make much money. Based on unbelievably detailed records of an actual Chicago neighborhood gang, the author found that, while the leader (who's now in jail) made $100,000 a year (tax free) over four years, his officers made only $700 a month and his foot soldiers made only $3.30 an hour, less than the minimum wage. "They had no choice but to live with their mothers." He compared this scenario with a high-school quarterback (position in American and Canadian football) and an editorial assistant.
Where Have All the Criminals Gone?          The common assumption was innovative policing strategies, increased number of police, increased reliance on prisons, changes in crack and other drug markets, aging of population, tougher gun control law, a stronger economy and other secondary ones.  The author compares the situation of abortion ban in Romania starting from 1966 to the legalizing dates of abortion in the US. The relation of causality between abortion and crime drop is further supported by evidence from the states that introduced earlier the policy of not banning the right of the woman to control the time of birth.          
What Makes a Perfect Parent?  W hat is important in parenting is who you are, not what you do.   The author estimates that a child is more than 100 times more likely to die in a swimming pool than playing with a gun Positive parenting outcomes are linked more strongly to factors such as socioeconomic status and parental education than any specific parenting practices. Important factors  in determining high standardized test scores in children include highly educated parents, high socioeconomic status, maternal age of greater than thirty when the child was born and low birth weight. Not  important factors  are: the family is intact, the parents recently moved to a better neighborhood, the mother didn't work between birth and kindergarten, visit to museums, regular spanking, watching television, reading to the child every day.
Would a Roshanda by Any Other Name Smell as Sweet?  Obsessive or not, any parent wants to believe that she is making a big difference in the kind of person her child turns out to be. Otherwise, why bother? This is proved by the booming baby-naming industry. in 1958, a New York City man named Robert Lane decided to call his baby son Winner. Three years later the 7 th  boy was named Looser. It was explained that the deeds were opposite. The Temptress example, actual name intended Tempestt Bled-soe  Black and white habits completely differ. Distinctive names by blacks A unique super black name signal of solidarity  with the community
