A Brief Tour of Craig Feied's Mind

We write at some length in SuperFreakonomics about a physician and technologist named Craig Feied, who is responsible for not only for a lot of medical innovation but who looks at problem-solving in a resolutely unorthodox manner.




Sticking to What I'm Good At

My wife and I did two hours of volunteer work on Maui, trying to remove sea grape, an invasive species. Twelve people in total had to divide the tasks of using large shears, raking brush, and hauling away all the cuttings.



Perfect Pitch

I recently attended my third Renaissance Weekend in Charleston, where among the normal cornucopia of ideas and fellowship, Sam Horn was incredibly generous in helping me sharpen my elevator pitch for a new project.



Are Women Being Taken for a Ride?

According to sociologist Pepper Schwartz they are — as car passengers. Schwartz reports that even in households that consider themselves feminist, men are far more likely to take the keys when the couple rides together. Does the evidence back her up?
I’ve been working with the American Time Use Survey, a great data set collected by the Department of Labor. The ATUS is chock-full of fun facts; for example, American adults report spending more than two- and-one-third times more time at gambling establishments than at museums.



What If They'd Said Yes?

Unredacted, the National Security Archive’s blog, has posted Lee Harvey Oswald’s request to the Soviet Union for citizenship. “I want citizenship,” Oswald wrote, “because I am a communist and a worker; I have lived in a decadent capitalist society where the workers are slaves.”



Cold, Hard Cash as a Handwashing Incentive

Whenever you write a book, it’s interesting to see which parts of it people respond to en masse. With SuperFreakonomics, the global-warming chapter has certainly gotten its fair share of attention, and Levitt noted a lot of feedback about the perils of drunk walking.



Quantifying Teacher Effectiveness

Teach for American (TFA) is known for putting recent college graduates in low-income public schools for two-year teaching stints, a mission that has produced a lot of passionate debate. The organization’s founders hope that these young teachers will eventually become education leaders and advocates – and many of them have.



If It's Raining, You Might Want to Reschedule That Interview

It is no secret that weather affects mood, and even behavior. The Bagel Man we wrote about in Freakonomics, who ran an honor-system business, received lower payments during foul weather. Now along come Donald Redelmeier and Simon D. Baxter from the University of Toronto with an interesting question: do applicants to medical school suffer if they happen to be interviewed on a rainy day?



A Chinese Spit Crackdown

As the Associated Press reports, the Chinese city of Guangzhou has introduced a strong incentive to discourage spitting in public: residents lose their homes if they get caught spitting seven times within a two-year period.



What Are Economists Talking About?

O.K., this is a pretty crude analysis. But still, this year’s conference suggests to me that the economics profession is healing itself.




What's Next: A Do-Not-Knock Registry?

John List had better be careful. His research is very valuable to the philanthropic community; but if this latest paper engenders a public outcry for a “do-not-knock” registry, he might quickly become a pariah.



My Grandfather Before Computers

My siblings, cousins, and I were talking about our paternal grandfather recently. He was very bright, but uneducated (immigrated to the U.S. at age 10). He worked in the garment industry, his best job being as a cutter — figuring out how to waste the least amount of cloth in creating a garment.



China's City of the Future

Al Jazeera reports on one of the projects driving China’s magical 8 percent GDP growth. Ordos is a modern, luxurious “city of the future” in Inner Mongolia, built entirely over the last five years with government funds. It’s also a ghost town with almost no residents or businesses.




LED Astray

LED traffic lights may be the wave of the future. But do they have some unintended negative consequences?



Yes We Can? Paul Volcker's Not So Sure

Charlie Rose interviews Paul Volcker, longtime former chairman of the Federal Reserve and currently the chairman of the Economic Recovery Advisory Board. Volcker talks bluntly about fixing the broken financial system, compensation on Wall Street, the future of the American economy, and the Obama administration’s performance so far. Volcker is particularly pessimistic about getting things done in Washington: “The American political process is about as broken as the financial system.” [%comments]



R.O.I. on Cancer Spending: Better Than We Think?

It is commonly thought that the nearly-40-year “war on cancer” has largely been a failure, since the age-adjusted mortality rate for cancer is essentially unchanged over that time. But that’s a deceptive metric. Consider this…



Engineers Among the Terrorists

A study by sociologists Diego Gambetta and Steffen Hertog reveals that engineers are “three times more likely to become violent terrorists than their peers in finance, medicine, or the sciences,” as reported in Slate. So why the career change?



The "Sole Purpose" of SuperFreakonomics

Here is a multiple choice question for you.
Read the following passage, taken from SuperFreakonomics:
If you know someone in southeastern Uganda who is having a baby next year, you should hope with all your heart that the baby isn’t born in May. If so, it will be roughly 20 percent more likely to have visual, hearing, or learning disabilities as an adult.



Are Economists Cheap? Or Do We Just Believe in Comparative Advantage?

The front page of Saturday’s Wall Street Journal tells us that “Economists are cheapskates.” The article by Justin Lahart is hilarious, recounting the foibles of those of us who sometimes take our classroom lessons about economizing a step too far – particularly when it comes to economizing on time.



Decision-Making Master Ralph Keeney Answers Your Questions

We recently solicited your questions for Ralph Keeney, a decision analyst at Duke University’s Fuqua School of Business.
In his answers, you’ll find that Keeney discusses how to avoid making the wrong decisions, how to figure out what you really want, and why neither psychologists nor economists have definitively figured out how to make good decisions.



Why I Love Scientists

Two articles in Harvard magazine remind me why I am so optimistic about scientific breakthroughs making the world a better place.




In Defense of GDP

My recent Marketplace commentary focused on the recent Sarkozy Commission report, which re-examined the usefulness of the usual economic indicators, like Gross Domestic Product (or GDP).
The report raises many of the usual shortcomings of GDP. And I agree with each of their criticisms. Much of this was summarized 40 years ago, in a famous Bobby Kennedy speech:



The Checklist Manifesto

If there is one topic that I have no natural affinity for, it is checklists. I don’t use checklists. I’m not interested in checklists.
Yet, against all odds, I read Atul Gawande’s new book about checklists, The Checklist Manifesto in one sitting yesterday, which is an amazing tribute to the book that Gawande has crafted. Not only is the book loaded with fascinated stories, but it honestly changed the way I think about the world. It is the best book I’ve read in ages.



From Cap and Trade to Carbon Farming

There’s really no need to panic over the prospect of EPA dominance. Instead, industry should take the hint that’s it high time to push hard for climate-change legislation. Sure, the move by the EPA to exercise regulatory authority over carbon — a power granted to it by a 2007 Supreme Court ruling — was designed to give President Obama moral leverage in Denmark. But it also serves as a presidential prod to Congress to pass a climate-change law. No matter how you feel about global warming, greenhouse-gas emissions are not going to go unregulated. I suspect Obama ultimately nudged the EPA because he wants the U.S. Congress to do the regulating. Industry should support him on this.
