Some of his conclusions are less than earth-shattering. For example, African-American names (DeShawn, Latanya) don't influence African-American test performance. As a second example, Levitt compiled data regarding online dating websites and concluded that bald men and overweight women fared badly. Not rocket science.
However, Levitt livens up the book with some controversial discussions. He believes that the dramatic drop in crime in the 1990s can be traced to Roe v. Wade. He thinks that the children who would have committed crimes (due to being brought up by impoverished, teenage, single mothers) are simply not being born as often.
He also writes about the man who more or less singlehandedly contributed to the KKK's demise by infiltrating their group and leaking their secret passwords and rituals to the people behind the Superman comic book (Superman needed a new enemy).
Interestingly, he also discusses how overbearing parents don't contribute to a child's success. For example, having a lot of books in the house has a positive influence on children's test scores, but reading to a child a lot has no effect. Highly educated parents are also a plus, while limiting children's television time is irrelevant. Similarly, political candidates who have a lot of money to finance their campaigns are still out of luck if no one likes them.
In the chapter entitled "Why Drug Dealers Live With Their Mothers," Levitt explores the economics of drug dealing.Read more ›
The book, co-authored by Stephen J. Dubner, is breezy and anecdotal, which is an effective format for presenting a lot of sociological trends without being dry or losing the scintillating reportage in dense prose.
The lesson of this book is that we should be leery of trusting society's common assumptions or common wisdom. In other words, the book encourages us to keep our mind alert and break out of the mold in the way we see things. By looking at social trends with a fresh eye, the book succeeds at making economic trends a fun, adventurous endeavor.
If I were to criticize the book, it would be that it is too short. It's barely 200 pages and if you take out the blank chapter pages, the charts, the lists, and so on, it's really closer to 150 pages. Because the material is so current and topical, the method of "freakonomics" presented here would make a good format for a monthly magazine. My guess is that there will be many sequels.
As any statistician will tell you, one of the major pitfalls of their field is the confusion of correlation and causation. Just because X and Y have similar trends does not necessarily mean that X caused Y or that Y caused X. Numerous times throughout the book, Levitt and Dubner chastise various experts, pundits, and conventional wisdoms for failing to observe this basic tenet. Yet so tempting is this trap that the authors fall right in along with their targets.
Take, for example, the chapter on parenting. A full six paragraphs are devoted to warning about correlation versus causation, the caution of which is thrown immediately to the wind with a set of highly dubious stabs at the causes of various correlations regarding parenting. The data in question comes from Levitt's regression analysis of numerous factors which conventional wisdom believes may play some role in the academic outcome of children. So, for example, correlations were found between a child's test scores and the number of books the parents have in their house, but not how often the parents read to the child. So far, so good. The authors then conclude from similar datapoints that it is the nature of the parents' lives that influence a child's scores, not what the parents do. Granted, it has a certain logical appeal, but it amounts to no more than an educated guess. What's wrong with that? you may ask.Read more ›

What an interesting book. The first chapter is great, then the second chapter is surprising. The conclusions are further and further drawn into the theory land. Read morePublished 9 days ago by Lucy Kuala
Fantastic book that really helps open one's eyes to good analysis practices (e.g. correlation is not causation). One of the first books I pick after a huge hiatus from reading. Read morePublished 10 days ago by Deng
