Which is more dangerous, a gun or a swimming pool? What do schoolteachers and sumo wrestlers have in common? Why do drug dealers still live with their moms? How much do parents really matter? How did the legalization of abortion affect the rate of violent crime?

These may not sound like typical questions for an econo-mist to ask. But Steven D. Levitt is not a typical econom...more

This was an interesting book. I say it was interesting because I started liking it (a lot) when I first read it, as time passed I liked it less and less. In that way I call it a candy book, tastes good at first but leaves you worse off for reading it.

In my opinion, there are two problems with the book: First, Stephen Dubner comes across as a sycophant. Way to much of the book is spent praising Levitt. Secondly, I was disappointed in the lack of detail provided about Livitt's hypothesis. I wante...more

Sure, this book was a compelling read that offered us all some great amo for cocktail party conversation. But ultimately I think most of what Leavitt claims is crap.

He dodges accoutability with the disclaimer about his book NOT being a scholarly work, but then goes on to drop statistics, theories and expert opinions. These assertions laid, he doesn't provide readers with enough information to critically examine his perspectives.

Ultimately I have a problem with the unquestioned, unaccoutable rol...more

Recommends it for: People Who Appreciate the Value of Social Science
I guess some people don't like this book because it's not centered around one theme. Instead, it's more about the seemingly diffuse academic work of one of the authors Steven D. Levitt (the other author is a journalist, Stephen J. Dubner). Levitt is something of an economist but more like a social scientist using the tools of Microeconomics applied to other fields that happen to catch his interest (often having something to do with cheating, corruption, crime, etc.). In the back of the book he m...more

I loved this book, though I think the title is a bit misleading. It's not really about economics. In fact, he's showing you what interesting things you can discover when you apply statistical analysis to problems where you wouldn't normally think of using it. I use statistical methods a fair amount in my own work, so I found it particularly interesting. The most startling and thought-provoking example is definitely the unexpected reduction in US urban crime that occurred towards the end of the 2...more

Recommends it for: People who know data
Yes, zero stars.

There is one segment of this book that reports use of a dataset I know very well -- the Fatality Analysis Reporting System (FARS) data. From what details they put into the book, it's fairly clear that the researchers did not research the reliability of the data elements they chose to use from FARS. In particular, their analysis rests on the ability to identify uninjured children in vehicles that were involved in fatal crashes. FARS has data elements for this, but the reliability...more

I am indebted to airport bookstores. And I am thus indebted to such an extent, that I can confess to arriving early for any flight departing from an airport with a bookstore for the sole purpose of securing a few additional minutes to browse books. If it were not for the practicalities of travelling, I would probably have bought this book much sooner than I did for I had been securing extra minutes in airport bookstores just to read through another chapter long before I actually bought it.

Levitt makes the lofty claim that economics is not swayed by moral sensibilities - it's a pure numbers game of course! However, not knowing much about him beyond his affiliation with the University of Chicago and what was written in the book, I can surmise that he is conservative, or at least what today would be inappropriately labeled "moderate." Is this a bad thing? Not necessarily...or at least I don't view it that way. Does it affect his conclusions? Absolutely. Levitt assumes his assertion...more

The Basics:

Freakonomics isn’t really about any one thing, which makes it a bit hard to summarize. In essence, it’s economist Steven Levitt playing around with economic principles and basic statistical analysis to examine various cultural trends and phenomena. He tackles a variety of questions, from whether or not sumo wrestlers cheat (they do) to whether or not a child’s name determines his success (it doesn’t). He does this all through examining statistics and data, trying to find facts to back...more

As the old joke goes, the questions in economics exams are the same every year; only the answers change.

I found this book to be really fascinating. Chapter 3- Why do drug dealers still live with their moms, was very illuminating. I like the questions they posed and the connections they came up with. I was quite surprised about the American school system, especially the fact that teachers often used cheating methods to make sure their students scored well in standardized tests.The section about how given names may influence one's future was quite gloomy in some ways, especially as there's evidence...more

There are at least two ways you can read Freakanomics – as a fun and interesting little book that uses data to tell us little things about ourselves and the world. Or, you can see it as econometrics gone apeshit and finally taking over the world. I kind of view it as both.

That said, I really enjoyed reading this. I think Levitt has developed some useful tools that can tell us some interesting stuff about the way little corners of our world are organized. I also think it is a little bit batty to...more

Shelves: economics, 2008, own
An engaging read but not necessarily the scintillating, mind-blowing experience it had been hyped as.

Levitt and Dubner present their arguments well and their style makes the at-times daunting subject matter easier to approach and thus easier to digest. I don't read much non-fiction (for example) and even less stuff about economics but I found this book quick to get through and I was able to take away their message without having to labor through it.

That said, a few points:

Shelves: nonfiction
The most interesting part of this book was the introduction. Sad, but true.

Four stars for presentation. The prose is nearly invisible, which I suppose in this genre is preferable to the alternative. And the content is mildly interesting, in a "Huh. Wouldja look at that" sort of way, as though you saw a duck waddling through your back yard with jam on its head.

But insofar as it's meant to be the vehicle for a larger framework for viewing the world, this book is old news. You mean shit's connected...more

This is a very American book. Not just because all of the examples in it are set in the US, but also the hype about it is terribly American too. It has the tone of self congratulation that has sold a million self-help books. Which is a pity, as what it has to say is terribly interesting and amusing.

The stuff at the end about how the name you are born with affects your life is very interesting. Also the idea, that is clearly true, but I'd never thought of it before, that people give their daughte...more

One of the most interesting topics in Freakonomics, is that of bad assumptions in causality. These are made when people consider causality regarding a particular event, and they making assumptions that are affected by factors such as self-interest, prejudice, common sense, etc. The book shows that when the right questions are asked and their answers are searched in a bigger context, some unrelated causes may happen to trigger the original event. An example from the book is how crime rate had fal...more

Exceeds the hype! Easy breezy to read, a wealth of information that I would never have stopped to contemplate. I had just read the chapter on the KKK and the real estate agent when my car was totaled; it helped me choose a posture with the insurance adjusters that wouldn't result in a total ass-raping. The last chapter about names was simultaneously horrifying and hilarious. It is dismaying to confess, now, that I am more judgmental of people's names knowing the societal/economic trends behind t...more

After packing 5 books for my trip, I found myself sitting in the Philadelphia airport with nothing to read. My mom, instead of buying me Remember Me? or Change of Heart, handed me her copy of Freakonomics: A rough Economist Explores the Hidden Side of Everything by Steven D. Levitt and Stephen J. Dubner.

Freakonomics was a great back-up book. It was witty, insightful, and really made me think. What does the Ku Klux Klan like a group of real-estate agents? Why do drug dealers still live with their...more

You know, I really enjoy economics and I used to listen to the Freakonomics podcast so I figured I'd enjoy this book more than I did. I think it's lack of a theme (which the authors clearly warn readers about ahead of time) contributed to my overall "meh" attitude. Additionally, I found myself yearning for more than just Levitt's observations and findings. For example, simply stating that data shows higher abortion rates yield lower crime rates and then not delving too deeply into the reasons th...more

Freakonomics by Steven D. Levitt and Stephen J. Dubner didn't impress me as much as I thought it would. A book about economics and finding correlations in things you wouldn't necessarily surmise, Levitt and Dubner seem to be really arguing that the defining indicator behind these studies is incentive. Perhaps it's my background in Psychology, but a lot of this seemed common sense to me. There were some parts I really enjoyed though. The two chapters I found to be the most interesting out of the...more

This book is not the super-awesome, totally-in-your-facer that, like, "society" or whatever would like you to believe it is.

If pressed, I'd assign this book to a category I'd call "Books That People Who Love Malcolm Gladwell Might Also Enjoy." There's no doubt that Steven D. Levitt is an expert number-cruncher, organizer, and researcher. The conclusions with which he attempts to wow the reader, however, are specious, hyperbolic, and generally lame-o-zoid.*

Here's an example: The author explains...more

A fascinating book that taught me a lot of things about myself and other people that were distinctly uncomfortable. Herewith some of the tidbits I picked up.

* About 10% of the population are happy to commit some sort of fraud, even if it just consists of not paying for their lunchtime sandwiches.
* IQ is inherited not nurtured
* On the whole we don't like old people.
* Attractive men are rich, tall and have a full head of hair.
* Attractive women are pretty, blonde and not too successful.
* The intro...more

Superficial, lleno de anécdotas y explicaciones enrevesadas sin ninguna base más allá de la correlación. Este es el nivel de la economía.

Hay un punto que resulta especialmente ofensivo: Levitt repite una y otra vez "ya sé correlación no es causa" y añade sistemáticamente "pero...", y da una explicación causal de libro. El análisis de regresión es llamado "una sofisticada herramienta de los economistas", que "permite controlar variables". Esto es la peor interpretación posible de la regresión, qu...more

Economics is not widely considered to be one of the sexier sciences. The annual Nobel Prize winner in that field never receives as much publicity as his or her compatriots in peace, literature, or physics. But if such slights are based on the notion that economics is dull, or that economists are concerned only with finance itself, Steven D. Levitt will change some minds. In Freakonomics (written with Stephen J. Dubner), Levitt argues that many apparent mysteries of everyday life don't need to be...more

الكتاب : اقتصاديات غريبة

الكتاب ألفه صحفي و استاذ جامعي في الاقتصاد في 2004. بيع منه اكثر من 4 مليون نسخة في العالم، كان مدونة ثم برنامج إذاعي و انتهى الحال بكتاب ثم فيلم وثائقي... ثم نسخة اخرى من الكتاب " اقتصاديات سوبر غريبة" و شركة استشارات اقتصادية يعمل فيها استاذ حاصل على نوبل في الاقتصاد.... بنفس الاسم!
بحسب ما فهمت من الكتابات عن الكتاب، انه يعالج مسائل اقتصادية من منظور مختلف... يحلل نتائج احصائية و يخبر القارئ بنتيجة تحليل الكتاب المفاجئ للمعتاد او المعروف.

Disappointed in the wordiness and round about way the authors' presented their data. The chapter introductions were so far away from the chapter contents it was humorous. I did notice how the authors' went around their elbows to get to their thumbs and tried to show a correlation, but I found sifting through the multitude of off-topic data tiresome.

Also, the way they presented their data took forever for them to get to the point. Often, they contradicted or repeated themselves or beat a topic in...more

I assumed Freakonomics would be a book that used statistics to debunk various societal hysterias and fearmongering in a semi-humorous way. I quickly realized what I was in for when early in the book when the authors gave their background as Harvard Jews and profiled a guy that infiltrated the KKK for the ADL. The story sounds at least partially made up.

It then jumped into predictable white guilt inducing trash and goes into mental contortions using "data" and sociological explanations for black...more

Freakonomics should definitely be listed as one of the books I'm glad I read them. Instead of directly writing about any sort of theories or laws of economy, Steven.L focuses on social issues that could explain many things previously ignored (or intentionally avoided). The overall writing style and structure of book are very similar to those of Malcolm Gladwell's books. Interesting and unexpected questions such as "What do Schoolteachers and Sumo Wrestlers have in common?" or "Why do drug dealer...more

For a book that so heavily relies on (mostly) untested assumptions, the repeated, passionate references to the distinction between causality and correlation is impressive if not audacious, to say the least.

Suffice to say, “"As Levitt sees it, economics is a science with excellent tools for gaining answers but a serious shortage of interesting questions".

Exactly, Stephen. And that would work extremely well as an inside joke too. Unless you are implying that, in contrast with the usual textbook...more
