Bring Your Think Like a Freak Questions for Levitt and Dubner

book-TLaFOn May 12, Levitt and I will publish our third book, Think Like a Freak. We cannot wait for you to read it. Here’s how the publisher describes it:

The New York Times-bestselling Freakonomics changed the way we see the world, exposing the hidden side of just about everything. Then came Super-Freakonomics, a documentary film, an award-winning podcast, and more.

Now, with Think Like a Freak, Steven D. Levitt and Stephen J. Dubner have written their most revolutionary book yet. With their trademark blend of captivating storytelling and unconventional analysis, they take us inside their thought process and teach us all to think a bit more productively, more creatively, more rationally—to think, that is, like a Freak.

Levitt and Dubner offer a blueprint for an entirely new way to solve problems, whether your interest lies in minor lifehacks or major global reforms. As always, no topic is off-limits. They range from business to philanthropy to sports to politics, all with the goal of retraining your brain. Along the way, you’ll learn the secrets of a Japanese hot-dog-eating champion, the reason an Australian doctor swallowed a batch of dangerous bacteria, and why Nigerian e-mail scammers make a point of saying they’re from Nigeria.

You can read more about the book, check out our tour dates, and of course preorder it: the book will come in all formats including e-book, audio, large-print, and in translation around the world. We will also start up our fee-signed-bookplate-mailing program so that you can get your books autographed.

How can we best "train" ourselves out of loss aversion (to our advtantage)?

Is there a way to logic someone out of a mindset they did not logic themselves into?

How do I share all this great information with others without being preachy?


Is a barista with a PhD good for society, or is it a waste of resources?

Is "overeducating" people bad, or is education an intrinsic good?

Steve Beckmann

What now? I am in my late 50's. I have enough money saved for retirement, really no need to continue to work. Shouldn't I get out of the way and let the next generation have their turn?

But, having just spent the last two weeks in Florida, I have to say "no way" when considering the typical retirement life.

What is the best use of my time now? How can I maximize the value of my time?

I can keep working and adding to my already adequate savings. At least until my mental capacities diminish, my experience will always trump that of the next generation. Should I continue to work because I can't think of anything better to do?

I can volunteer, but the opportunities are primarily menial, below my intellectual capacity. My middle manager skills don't translate well to the volunteer market.

As Americans gray, what are we supposed to do?


Do fire sprinklers cost more money to install, maintain, inspect, and repair than the cost of the fires they protect us from?

Why is Steve Leavitt so concerned about his children's education? Specifically, he mentioned on one of your previous FAQ's that he had chosen his neighborhood based on the schools. I was surprised my Steve's "conventional" attitude o this matter. I have heard some research - possibly reported on your podcast - that school's/environment/upbringing don't affect a person's outcome nearly as much as we think they do (it may have been Bryan Kaplan's work).

Parents these days are quite obsessed with where to send their kids to school. My wife and daughter are wringing their hands about which junior high she should go to. I just want her to go to the closest public school so she can ride her bike and we don't have to pay tuition. I know that she will be fine in any case, mostly because of the genes my wife and I have given her. Secondarily, we make sure she does her work, help her with her questions, stay involved, etc. Isn't this the right attitude for an economist?

Also, is Dubner similarly obsessed with his children's schooling?




What are good tips for success (marriage) in online dating?

Steve Nations

I hate the NCAA and pretty much everything it stands for. Have you guys looked into your crystal ball and do you have any thoughts on what the drawbacks might be if college athletes to gain more rights and more money? And what techniques should a Freak use when arguing with somebody about the issue of college sports, with respect to an idea that everybody just seems to take for granted even though it's just made up out of nothing. The idea that college athletes should be amateurs is so engrained in people's minds, and yet I see no actual reason for it, and it seems to just be a figment of the NCAA's imagination.

Regarding education, seems like the best schools have a couple of things going for them.

1. they are in an affluent area, where the districts have the money to support them.
2. they have parents that are involved with the education process
3. The students have a stronger sense that education is a priority.
4. Education seems to have stronger community ties.

I think that the last three are more of direct result of the first. With that in mind, how can we change the ideas and thinking behind education in under served communities. In a world where we tell everyone that education is "free", how do we get people to think more about the other costs involved in educating children. In other words, how can a government and a society at large help to change the logic of "free" education in less affluent areas and get Numbers 2,3, & 4?


First, to comment on the education thread because some people think that subsidizing private education threatens public schools. My "freaky" thought is that, if subsidies are small, they could help public schools by lowering class sizes. Perhaps there are other examples of this in society.

Second, there is much concern in the news about faulty ignition switches in GM cars, but it could be a signal vs. noise problem that is hard to detect, rather than intentional non-disclosure. Before we impose punitive damages or additional regulations, can Freakonomics provide some rational approaches to managing such risks?

What do you think about the 'Effective Altruism' movement?

Barry Carter

I've always subscribed to the theory that 'dog people' are much nicer than 'cat people'. Dogs take a lot more caring for than cats, so the owners are therefore more generous have giving. Also dogs display loyalty, which is important in nice folk.

Is there any data to back this assertion up?


Has anyone ever studied whether climate plays a role in test scores? Teacher's unions like to point to higher scores in unionzed states(not southern states), as proof of their effectiveness, but what about being a prisoner of weather and seeking knowledge out of boredom?
