Cities, Before and After

A site called Oobject features juxtaposed shots of cities before and after major events like war, natural disasters, and “property speculation.”



Monetizing Frustration

When I’m upset about the minor annoyances of life, I sometimes find it helpful to think of the price I’d charge for enduring the annoyance. For example, when my wallet was stolen, I wondered how many dollars would someone have had to pay me to consent to the taking.




ClimateGate as Rorschach Test

In the 10 days since we first blogged about “ClimateGate” – the unauthorized release of e-mails and other material from the Climate Research Unit (C.R.U.) at East Anglia University in Norwich, England – it’s become strikingly clear that one’s view of the issue is deeply colored by his or her incoming biases. No surprise there, but still, the demarcation is clear. One of the best indicators: when you stumble onto a blog post about the topic, you can tell which way the wind is blowing simply by looking at the banner ad at the top of the site: if it’s for an M.B.A. in Sustainable Business, you’re going to hear one thing about ClimateGate; if the ad shows Al Gore with a Pinocchio nose, meanwhile – well, you get the idea.



Chicken Eggs and Swine Flu

Jason Kottke explains how the H1N1 vaccine is made — including the step where part of the virus is injected into eggs, where it incubates for two to three days before being removed.



Quotes Uncovered: Finally, the Whole Nine Yards

Today I will give my long-awaited response to the many questions about the leading phraseological enigma of our time, namely the origin of the phrase “the whole nine yards.” I am sorry to disappoint by having no definitive answer, but the reality is that many of the major etymological riddles have no known answer.



Can Gerbils Read Maps?

National borders may sometimes seem like arbitrary lines drawn on a map, but a new study from the University of Haifa reveals that those borders mean something to the resident animal populations.



Uncertainty and the Fed

There’s a strange view out there that with unemployment above ten percent, and inflation nascent, the Fed should be thinking about raising interest rates. Yesterday Philadelphia Fed President Charles Plosser attempted to explain his view:




Is the Paradox of Choice Not So Paradoxical After All?

The psychologist Barry Schwartz’s book The Paradox of Choice (here’s his TED talk on the topic) was, for me at least, very persuasive. It made a compelling if counterintuitive argument: even though many people (economists especially) argue that more choice is almost always a good thing, Schwartz argued that too much choice is actually a bad thing, causing decision paralysis and unhappiness.



No Need to Reinvent the Nudge

A Boston Globe article explains how “positive deviance” — a way to change behavior by using “nudges” that already exist in a community, rather than imposing them from the outside — substantially decreased malnutrition in a Vienamese village: researchers observed children who looked more nourished than others, found that their families were feeding them crabs — considered a low-class food — and encouraged neighbors to follow the family’s good example.



When the Weather Puts Food on Your Table

A lot of industries are obviously weather-dependent — agriculture, tourism, etc. — but I hadn’t known that the traditional production of roofing slate in the U.K. was also at the mercy of the weather. Here is but one of many fascinating things you can learn from Simon Winchester’s excellent book The Map That Changed the World, about the proto-geologist William Smith:



The Dangers of a Live Twitter Feed

It seems to make all the sense in the world. You are WPMI-TV, the NBC affiliate that covers southern Alabama and some of the Florida Panhandle, and you rent a big electronic billboard to promote your nightly news and weather team.




The Global Warming Email We've All Been Waiting For

I got a good chuckle out of this piece by George Monbiot in the Guardian about the recent global warming e-mail controversy.
My view is that the emails aren’t that damaging. Is it surprising that scientists would try to keep work that disagrees with their findings out of journals?



The Year's Top Thinkers

Foreign Policy released its list of 2009’s Top 100 Global Thinkers. The No. 1 spot goes to Ben Bernanke for “staving off a new Great Depression,” while Obama takes No. 2 for “reimagining America’s role in the world.” A few of our old favorites also made the list.



Bagel Danger

Americans ate an estimated 3 billion bagels at home last year, an average of about 11 per person (this doesn’t include bagels eaten at work, where a not-completely-insignificant number are delivered by bagel economist Paul Feldman). And in the course of slicing up all those bagels, 1,979 people cut their fingers so badly that they ended up in an emergency room.




A New Car or Ten Thousand Lattes?

At Big Think, Dan Ariely discusses ways to think about money so you splurge less — like equating expensive wine with gallons of milk and making paying hurt a little more.



Why Don't Reputations and Salaries Rise Together?

Our new study poses a conundrum: in a professional market (for economists), having more scholars pay attention to your research raises your reputation and your salary. Conditional on that attention, though, writing more papers lowers your reputation — but it raises your salary!



More Money, More Fishing

The island of Kiribati began to subsidize coconut harvesting in the hopes of encouraging fishermen to switch to the coconut trade and thereby help preserve Kiribati’s reefs from the ravages of overfishing.



Sex and the SUV: Men, Women, and Travel Behavior

Indeed, the conclusion of the slogan “you’ve come a long way, baby” ironically demonstrates that women had not come quite as long a way as they might have hoped. Even now, important gender differences persist, and they show up quite clearly in the realm of transportation.



Some Turkey Facts to Consider, and Why You Don't Want Al Gore Doing the Roasting

‘Tis the season for turkey shopping, and the price is right. According to this Wall Street Journal squib, the price of whole frozen turkeys has fallen from 94 cents per pound last year to just 66 cents per pound, with Wal-Mart leading the way, selling turkeys for just 40 cents per pound. (Note: price estimates vary.)



Physician, Disinfect Thyself

We spend a good bit of time in SuperFreakonomics writing about doctors’ hand hygiene: specifically, how important good hand hygiene is in order to cut down on hospital-acquired infections and yet how historically it has proven difficult to enforce.



The Spiked-Drink Myth

Drinking alcohol puts people at high risk for all kinds of misfortunes. Exposure to date-rape drugs, however, doesn’t seem to be one of them.
In a study published in the British Journal of Criminology, more than half of the 200 university students surveyed said they knew someone whose drink had been spiked. But judging from evidence in police and medical records, these numbers are probably highly inflated.



Today, I Am a Lawbreaker: A Freakonomics Contest

Yesterday, and for much of the past year, I regularly did something that was perfectly legal.
Starting today, if I do the same thing, I am breaking a New York State law.
What is it that I’m doing?
The first correct answer earns a signed copy of SuperFreakonomics or a piece of Freakonomics schwag.



Need to Know How Charitable You Are? There's an App for That

Chapter 3 of SuperFreakonomics, called “Unbelievable Stories About Apathy and Altruism,” takes a look at the research of John List (the Univ. of Chicago economist, not the notorious murderer of the same same — although the same chapter does cast a new light on a famous murder as well). List’s research challenges the prevailing wisdom on a few decades’ worth of lab experiments which seemed to prove that human beings are innately fair or even altruistic.



Just in Time for Christmas: Free Autographed Bookplates

If you’d like to turn your garden-variety copy of SuperFreakonomics (or Freakonomics) into a nifty autographed copy that suddenly seems much more gift-appropriate, you can sign up here for a free bookplate that is hand-signed by Levitt and Dubner. If all goes well, the Freakonomics elves will dispatch your bookplate via mail in plenty of time for the holidays. It’ll look something like this:



Why California's Tuition Hike Might Be a Good Thing

Students at University of California schools have been protesting the decision of the Board of Regents “to raise undergraduate fees – the equivalent of tuition – 32 percent next fall.” But higher tuition, if it is accompanied with higher financial aid for lower- and middle-income students, improves equity. As Aaron Edlin and I wrote back in 2003:



What's Your Best Externality?

The last two years I’ve run an “externality” contest in my giant intro class, offering $5 to the student who comes up with the best example.
