Can you guys turn your attention to the truth behind the gun control debate. Do more guns really equal fewer gun crimes?

Sam Taylor

(I guess this question is more directed towards Levitt)

How did you determine topics to research? How do you deal with topics where data is generally unavailable?

(I'm a grad student working on a paper for my Advanced Econometrics class and could use a little inspiration!)


hello guys.

does anyone know how much money, total, there is in the world? And if it is so that value i.e. money can "dissapear" stock exchanges etc. what is the theoretical minum value of the whole world?

Javier Luna Victoria

It is true –according to Milton Friedman- that illegal immigration is good as long as is kept illegal?


how do you guys deal with wine snob friends after your analysis? do you bite your tongue or say something? If so, what do you say?


I find it incredibly annoying that normally economically rational people have a total blind spot for immigration. If you were President, what immigration policy would you be pushing for?

All about the health exchanges - Where do you find your own states? What if they ate relying on the Feds? How does one effect a "rebate "? By what mechanism can one compare coverage? All that and more....please & thank you! eaee


Is there a relationship between the wealth and/or income inequality in various states in the US and the political leanings of those same states?

For instance, does Texas have a higher or lower income inequality than Massachusetts?

Or, what correlates to wealth and/or income inequality in various states when only evaluating an individual state?

Rafael Santos

Should the US and China enter a new cold war to save the world's economy?

What is driving up the "high cost" of healthcare? Is it our aging population? Longer life expectancy? Rising cost of drugs and their influence on the system? Or something else?

What is the most common logical or rational fallacy that you encounter, other than confusing correlation and causation?

Jeff Collier

I own two business in a metro market. More and more, we are being extended on payments from large businesses including contractors, manufacturers, and retailers.... not the normal 30 days, but some as long as 120 days. Think it would be interesting to see the real cost and effects these extensions of payments has on business and the economy. What are these large cash cows doing with this small amount of cash they are hording?


What would you recommend to students who are looking for a job which allows them to pay back their student loans as quickly as possible? Are investment banking and its cousins still the answer?

Question: Can you be too smart for your own good?

I have heard this used often however I tend to disagree that you can be too smart for your own good. The only example I can think of are Iran Nuclear Scientists being assassinated. Can you conjure up different examples besides persecution?


Speed kills - can you discuss the relationship between highways speed limits and wrecks/injuries. Why does America have such slow speed limits compared to the rest of the developed world (Especially our buddies in the EU), also what is the cost of those slower speeds in terms of lost production etc...


i think that one of ur topics was test forensics: how u can analyze test result data to discern if the results were doctored- have u heard of any such analysis for financial fraud? eg. are there any post hoc analyses of accounting fraud that may help to detect when firms are currently cooking the books?

I hope I've found the correct web location to send in a question. I was wondering if there is a Freakonomics spin on the "Where's George" phenomenon where $1 bills distribution is tracked via a web site.
Just in case you're not aware of this, groups of people stamp their $1 with a stamp identifying the bill that it can be tracked and each follower then enters the unique ID stamped on each bill.

So how about it, what can an inquiring freak glean from this data set?

Mark Greer

I would love to know the positive and adverse affects that speeding traps have on a local community. Are speeding traps setting us back, or do they improve our standard of living?

In all your statistical analysis to identify cheating AND experience with horse racing. Given the large amounts of money involved, but relatively few jockeys/owners/trainers, do you think some Triple Crown horse races are fixed?

I think specifically of a 50-1 horse, Mine That Bird, that ran a time faster than came from dead last to pass the entire field on a sloppy track. The horse never won a race before the KD and never won a race after.

Q: Is there a hidden cost to intelligence?

I feel a lot of people assume(wrongly?) there is a trade-off between intellectual and social ability. Certainly, Hollywood seems to have jumped on board with the stereotype (Sheldon Cooper, Urkel, Lisa Simpson, etc). I'm often eager to bring up new things I learn from the Freakonomics podcast(and others) in casual conversation. I'd like to know if intellectual individuals alienate themselves or spark interest and engagement in general when it comes to social interaction. Thanks!
