Blog

When Freakonomics.com was launched in 2005, it was essentially a blog (c’mon, blogs were a thing then!). The first Freakonomics book had just been published, and Stephen J. Dubner and Steven D. Levitt wanted to continue their conversation with readers. Over time, the blog grew to have millions of readers, a variety of regular and guest writers, and it was hosted by The New York Times, where Dubner and Levitt also published a monthly “Freakonomics” column. The authors later collected some of the best blog writing in a book called When to Rob a Bank … and 131 More Warped Suggestions and Well-Intended Rants. (The publisher rejected their original title: We Were Only Trying to Help. The publisher had also rejected the title Freakonomics at first, so they weren’t surprised.) While the blog has not had any new writing in quite some time, the entire archive is still here for you to read.

Good News: We're Getting Better at Not Killing Sea Turtles

Human-caused sea turtle deaths are down 94% since 1990 because of “fisheries-specific bycatch mitigation measures.” Basically, it means we’re getting better at not catching sea turtles in giant fishing and shrimping nets. A paper to be published in the November issue of the journal Biological Conservation compiles the first cumulative estimates of the number of sea turtles unintentionally caught across U.S. fisheries between 1990 and 2007 — before and after implementation of mitigation measures. The researchers are careful to point out, however, that they cannot account for off-the-books fisheries. They write in their abstract:

Our estimates represent minimum annual interactions and mortality because our methods were conservative and we could not analyze unobserved fisheries potentially interacting with sea turtles.

Before measures were put in place 20 years ago, 300,000 sea turtles were victims of bycatch, and 70,000 were killed every year.


Entitled to Know

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
jennifer atkinson asked:

“When did we start calling social security, medicare, and medicaid ‘entitlements’? Seems like they might well be deemed obligations.”

The Oxford English Dictionary does not yet include this sense of the word “entitlement,” but I believe that it originated with or was at least popularized by pioneering legal scholar Charles Reich. Reich used “entitlement” meaning “right to governmental benefits” in his landmark article “Individual Rights and Social Welfare: The Emerging Legal Issues” in the Yale Law Journal in 1965. He had earlier used the corresponding sense of the verb “entitled” in his even more landmark article “The New Property” in the Yale Law Journal in 1964.
Do any readers have any other quotations whose origins they would like me to attempt to trace?


The Testosterone Tradeoff: Hormone Decrease Makes Better Fathers

It’s official: having a baby will lower your testosterone levels. If you’re a man, of course. And while this may seem scary and vaguely emasculating, it’s actually a good thing, according to a new study by researchers at Northwestern University. While testosterone is good for some activities, like competing for a mate, it’s not great for other activities, like nurturing a newborn baby. Here’s part of the abstract:

In species in which males care for young, testosterone (T) is often high during mating periods but then declines to allow for caregiving of resulting offspring. This model may apply to human males, but past human studies of T and fatherhood have been cross-sectional, making it unclear whether fatherhood suppresses T or if men with lower T are more likely to become fathers. …Our findings suggest that T mediates tradeoffs between mating and parenting in humans, as seen in other species in which fathers care for young. They also highlight one likely explanation for previously observed health disparities between partnered fathers and single men.


Radio in Progress: Political Word Watch

For an upcoming Freakonomics Radio episode, we’ve been doing some research on media bias. We came across this paper by Northwestern researchers, part of a growing body of work that uses computational analysis to turn political speech into data. Simply by examining speech patterns, the researchers were able to predict the political affiliation of U.S. Senators with 94% accuracy.
They broke down the nouns, adjectives, verbs, and adverbs most common to each party. For instance: liberals use the adjective “gay” while conservatives favor “homosexual.” Adverbs preferred by liberals include “disproportionately,” “ecologically” and “indiscriminately”; conservatives favor “morally,” “objectively” and “constitutionally.”


How Does High Unemployment Affect Wages of Those Who Remain Employed?

Of course higher unemployment generally raises unemployment among men, women and minorities. But how does it affect the wages of workers who keep their jobs? I believe a new paper that I coauthored with Jeff Biddle is the first to use large amounts of data to address this question about cycles in wage discrimination. Here’s the abstract:

Using CPS data from 1979-2009 we examine how cyclical downturns and industry-specific demand shocks affect wage differentials between white non-Hispanic males and women, Hispanics and African- Americans. Women’s and Hispanics’ relative earnings are harmed by negative shocks, while the earnings disadvantage of African-Americans may drop with negative shocks. Negative shocks also appear to increase the earnings disadvantage of bad-looking workers. A theory of job search suggests two opposite-signed mechanisms that affect these wage differentials. It suggests greater absolute effects among job-movers, which is verified using the longitudinal component of the CPS.


What's the Best Way to Measure Poverty: Income or Consumption?

Yesterday we learned that 15.1% of Americans were living in poverty in 2010, the highest level since 1993, and up nearly 1 percentage point from 2009, when it was 14.3%. That data is based on an income measurement which shows that in 2010, 46.2 million Americans were living below the poverty line, defined as $22,314 a year for a family of four.
But income is just one way to measure poverty, and a particularly tricky (and narrow) way at that – so says Notre Dame economist and National Poverty Center research affiliate, James Sullivan, who believes that to measure poverty strictly by income fails to accurately reflect people’s true economic circumstances. Income alone ignores the effects of things like the Earned Income Tax Credit, Medicaid, food stamps, and housing subsidies. From a Notre Dame press release on Sullivan’s recent poverty research:

“Income received from food stamps, for example, grew by more than $14 billion in 2009. By excluding these benefits in measuring poverty, the Census figures fail to recognize that the food stamps program lifts many people out of actual poverty,” Sullivan says. “If these programs are cut back in the future, actual poverty will rise even more.”


Rise of the Apes via Miracle Grow

This is a Freakonomics guest post by Mark Changizi, an evolutionary neurobiologist, and Director of Human Cognition at 2AI. His new book Harnessed explores the evolutionary origins of language and music.
Rise of the Apes via Miracle Grow
By Mark Changizi
Add Miracle Grow to your tomato plants and you get tomatoes. Big tomatoes, but still tomatoes. What you don’t get are mobile, blood-thirsty tomatoes with a deep distaste for the classic tune, “Puberty Love.” That would require serious evolutionary design, something far more complex than Miracle Grow can handle.
Yet something very much like Miracle Grow works for giving chimps and gorillas human-level intelligence. Or, at least, that’s what you’d have to believe to accept the premise of the summer movie, Rise of the Planet of the Apes, where a grow-more-neurons drug aimed for Alzheimers is given to apes, who thereby become the cognitive equal of humans, replete with language.
Obviously, that can’t happen. Our human brain is not simply a bigger version of the same fundamental ape design. Rather, it possesses essential new software forged over millions of years of natural selection. Some believe there is new language software, a language instinct; while others believe, in contrast, that what’s new are general-purpose algorithms of the kind artificial intelligence researchers seek. A simple give-‘em-more-neurons mechanism can’t reproduce these sorts of designs.


The Day My Golf Dream Died

It sounded like a small explosion. That was the first hint that my dream was dying. I was standing on a driving range in Florida. Because I am completely and utterly obsessed with golf, there is no place I would rather be. It makes no sense, but I’ve stopped trying to rationalize it.
As much effort as I invest in golf, I’ve never really had any expectation that I would be an outstanding golfer. So when I’ve had the chance to play with some of the world’s very best golfers, like Luke Donald and Jason Day, it was not the slightest bit discouraging to see, up close, just how much better they are than me. I fully expected them to be as amazing as they are.
All my life I have been far more obsessed with how far I could hit a golf ball than with making low scores. I was an extremely short hitter as a kid, and much of my adult life has been devoted to making amends for that weakness. I’m still not an exceptionally long hitter, but I have probably added 40 yards to my average drive in the last four years. Those gains have fueled the (surely irrational) dream that perhaps I could add another 40 yards over the next four years, in which case I would be a long driver.


Why Is There a Rule Against Poetry Critics Quoting Poetry?

In a recent article, the poetry critic of the New York Times complained that to do poetry criticism right, it’s often necessary to quote extensively from a poem. Indeed, in the case of a short poem, it might be helpful to readers to copy the whole thing. But, the critic said, this can’t be done because it might run afoul of copyright law.
It is true that copyright law prohibits the unauthorized copying of any substantial part of someone’s poem, song, or other work. What does “substantial” mean? Well, in one recent case, a federal court held that rap group N.W.A.’s unauthorized sample of a two-second guitar chord was infringing. The court’s holding was clear: “Get a license, or do not sample.”
Is this a good policy? From an economic perspective, no. Use of a small bit of someone else’s creative work to build a new creative work rarely harms the economic interests of the first copyright owner, because most “derivative” works do not directly compete with the original. In the case mentioned above, no one thought that N.W.A.’s rap song “100 Miles and Runnin’” would lure potential paying customers away from Funkadelic’s “Get Off Your Ass And Jam.” (Note: neither song is safe for work.)


How I Know I Love My Wife

A year ago, my wife said to me, “I need you to do me a favor.” I knew that was bad news. A charity she is heavily involved with, Half the Sky, was planning an event in Chicago and she had volunteered me to be the speaker.
In principle, this was no big deal. I speak in front of groups all the time. I can talk about Freakonomics, SuperFreakonomics, and my academic research in my sleep.
I knew immediately, however, that this speech would be completely different. Although I often tell stories about myself and my life, they are never stories about emotions. I am one of the most closed off people you’ll ever find when it comes to emotional topics. I have never learned, or really even tried to learn how to express emotions. I’m not proud of this, it just is the truth.
There was no way, however, that I could speak at a Half the Sky event without opening up my emotions. Half the Sky is an amazing charity – perhaps one of the world’s best – doing incredible work with Chinese orphanages. The only events that ever fully penetrated my emotional wall were the death of my son Andrew and the subsequent, deeply moving process of adopting a daughter (eventually two daughters) from China. More than a decade later, the emotions associated with these two events remain shockingly raw, hiding just below the surface.


Bring Your Questions for Willpower Authors Roy Baumeister and John Tierney

What’s the most coveted human virtue — empathy? honesty? courage?
Or how about … self-control?
That’s the assertion of the new book Willpower: Rediscovering the Greatest Human Strength*, by Roy Baumeister, a research psychologist at Florida State, and John Tierney**, a New York Times science writer. The book builds off Baumeister’s research on the physical aspect of willpower, which he and his research collaborators found behaves like a muscle: it can be strengthened through exercise but it becomes fatigued from overuse. Willpower is generated in large part by sleep and diet, and feeds off of the glucose in our bloodstream.
Baumeister and Tierney argue that our ability (or inability) to exercise self-control is most often the key between success and failure. And it’s hard not to see their point: I type these words on the very day that a special election is being held in New York to replace the disgraced (and aptonymic) Congressman Anthony Weiner.


Wanna Buy a Tony Award?

People give to charities for all kinds of reasons – some more noble than others. But one important motivation is recognition. If Yale mandated that it would only accept anonymous donations, its fundraising would be decimated.
There are a lot of different ways to garner public recognition. If I had 3 million bucks to throw around, I’d think long and hard about trying instead to buy myself a Tony Award. For as little as $200,000, you might be able to purchase an 8% chance at winning a Tony.
Let me emphasize that this is at best a crude ballpark estimate. Over the last 5 years, 12.2 new plays have been produced on Broadway each year. For a play, which generally runs about $2.5-3 million these days, my friend Jack Thomas at Bulldog Theatrical tells me you can usually find yourself among those listed above the title for about $200,000. Some investors split this minimum ante and put up or raise just $100,000 each and get listed as Bulldog Theatrical / Cantab Theatrical.


Why Do Elected Coroners Underreport Suicide?

The WSJ reports on a new study that finds that elected coroners report 15% fewer suicides than do appointed medical examiners. The researchers looked at 1,578 counties with elected coroners, and 1,036 with appointed medical examiners, adjusting for poverty, marriage, household income, education levels and gun ownership. Their reasoning for the difference in reporting? Stigma and politics:

“Elected coroners would feel pressure because they are elected by the public at large and would be worried about antagonizing local community stakeholders who might badmouth them,” said Joshua Klugman, PhD, first author of the study and assistant professor of sociology at Temple University in Philadelphia. “For medical examiners, we think the pressure is still there, but it’s to a lesser degree. They feel insulated from that.”

In addition, the researchers looked at 174 appointed coroners and found that their reporting rate matched the medical examiners, instead of the elected coroners.
In general, suicide is a taboo subject. But not too taboo for us — if you haven’t already downloaded our latest podcast, do so and find out about “The Suicide Paradox.”


Is David Ortiz the New Yogi Berra?

Here’s what the Red Sox slugger had to say recently about the sour streak his team has been on lately, endangering its playoff hopes:

“There’s nobody to blame but everybody.”

If I were a CEO, or the president of something, or someone with even the slightest responsibility for anything, I would tuck this quote in my back pocket and whip it out when things get grim.


Study Shows Minorities Less Likely to Win Grants, Scholarships

A short paper recently released by Mark Kantrowitz, publisher of Fastweb.com and FinAid.org, is shaking up the discussion of race and financial aid – specifically, Kantrowitz writes that white students are disproportionately more likely to receive financial aid than their minority counterparts. Kantrowitz’s intro reads as follows:
 

This paper presents data concerning the distribution of grants and scholarships by race. It debunks the race myth, which claims that minority students receive more than their fair share of scholarships. The reality is that minority students are less likely to win private scholarships or receive merit-based institutional grants than Caucasian students. Among undergraduate students enrolled full-time/full-year in Bachelor’s degree programs at four-year colleges and universities, minority students represent about a third of applicants but slightly more than a quarter of private scholarship recipients. Caucasian students receive more than three-quarters (76%) of all institutional merit-based scholarship and grant funding, even though they represent less than two-thirds (62%) of the student population. Caucasian students are 40% more likely to win private scholarships than minority students.


Tiger vs. Dragon: A Demographic Comparison of India and China

One of the biggest story lines of the 21st century is going to be the continued economic rise of China and India. According to the World Bank, both countries grew at a rate of 9.1% in 2009. Here’s a chart of their growth since the 1960s:
While their recent growth has been roughly similar, China and India also boast the two largest populations on the planet. But a new study by RAND shows the giants heading down different demographic paths. From the abstract:

Demographic contrasts between China and India will become more pronounced in the coming decades, and these differences hold implications for the countries’ relative economic prospects. China’s population is larger than India’s, but India’s population is expected to surpass China’s by 2025. China’s population is older than India’s and beginning to age rapidly, which may constrain economic growth, whereas an increasing percentage of India’s population will consist of working-age people through 2030, giving India an important demographic advantage. How much these demographic changes affect economic growth will depend on several other factors, including the infrastructure, education system, and health care systems in each country and how well each country integrates women into its workforce.


Europe's Problem with Mental Illness

Along with a shaky currency, and fears of sovereign debt defaults, Europe has another problem on its hands: psychiatric disorders are now the biggest source of illness among Europeans.
A new study in European Neuropsychopharmacology shows that 38.2% of Europe’s population grapples with some kind of psychiatric problem. Depression, insomnia and anxiety top the list. Only one third of those afflicted receive treatment. Hans-Ulrich Wittchen from the Technical University of Dresden led the three-year study of mental health in 30 countries. Here’s part of the abstract:

No indications for increasing overall rates of mental disorders were found nor of improved care and treatment since 2005; less than one third of all cases receive any treatment, suggesting a considerable level of unmet needs. We conclude that the true size and burden of disorders of the brain in the EU was significantly underestimated in the past. Concerted priority action is needed at all levels, including substantially increased funding for basic, clinical and public health research in order to identify better strategies for improved prevention and treatment for disorders of the brain as the core health challenge of the 21st century.


Examining the EPA Cave-in: Does the Broken Window Fallacy Apply?

Did President Obama get the economics wrong earlier this month when he abandoned stricter air-quality rules, wagering environmentalist loyalty in a bid to avoid job losses from strict new ozone standards? Paul Krugman thinks so, calling the decision to wave off the EPA a “lousy decision all around.” But is Krugman right?
The short-run job-creating move, Krugman contends, would have been for Obama to promulgate the new ozone regulations, which would have forced firms in hundreds of counties across the country to replace and upgrade capital in order to comply with new, stringent pollution abatement requirements. He asserts that because the U.S. economy is in a liquidity trap, wherein conventional monetary policy is insufficient to induce firms to spend, the regulations could have accomplished what the Fed cannot. In such a “world of topsy-turvy,” as Krugman says, the usual rules of economics are thrown out, and even the “Broken Window Fallacy” ceases to hold.


Waiting for Free Cheeseburgers: Worth the Opportunity Cost?

There’s a long line of students snaking around the courtyard near my office. They’re queuing up to get a “free” cheeseburger, courtesy of Dave’s Hot and Juicy Tour of America, a Wendy’s promotion. A student near the current end of the line will spend 15 minutes in the sun to get the burger. A Wendy’s cheeseburger usually costs $2.99. I certainly wouldn’t be out there, even if I liked cheeseburgers.
If the student’s opportunity cost of time exceeds $12/hour, waiting for the freebie is a bad decision. But since there’s some evidence that people value time outside of work at 1/3 their wage, and since it is unlikely that many students’ hourly wage rates exceed $36/hour, standing out there is sensible on narrow economic grounds for nearly all students. But: This doesn’t factor in the likelihood of heat stroke—it’s 101º in the shade!

China's Suicide Rate Among the Highest in the World

September 10th is World Suicide Prevention Day. Timely, since our latest podcast is “The Paradox of Suicide.” It focuses on the specter of suicide and how, strangely, it tends to be more prevalent in rich societies than in poor ones.
One country not mentioned in the podcast is China, where suicide is definitely a cultural problem. Yesterday, China’s Center for Disease Control and Prevention announced that China’s official suicide rate is among the highest in the world. It’s so high, that someone tries to kill themselves every two minutes. Roughly 287,000 people commit suicide each year, out of a population of 1.3 billion. From the AFP:


Peg Tyre, Author of The Good School, Answers Your Questions

This week, we solicited your questions for Peg Tyre, education journalist and author of The Good School: How Smart Parents Get Their Kids The Education They Deserve. You responded quickly, and so has she, with answers to a handful of your education-related questions, ranging from textbooks, to No Child Left Behind.
This turned into a smart conversation on a topic that affects all of us. Education policy and reform is certainly something we’ll keep coming back to on the blog. Thanks to everyone for participating.


Why We Desire But Reject Creative Ideas

According to a new paper by researchers at Cornell, University of Pennsylvania, and the University of North Carolina, creative ideas make people uncomfortable. The paper, which is based on two studies from U. Penn. involving more than 200 people, is set to be published in an upcoming issue of the journal Psychological Science. Here’s an earlier ungated version.
From the abstract:

People often reject creative ideas even when espousing creativity as a desired goal. To explain this paradox, we propose that people can hold a bias against creativity that is not necessarily overt, and which is activated when people experience a motivation to reduce uncertainty. In two studies, we measure and manipulate uncertainty using different methods including: discrete uncertainty feelings, and an uncertainty reduction prime. The results of both studies demonstrated a negative bias toward creativity (relative to practicality) when participants experienced uncertainty. Furthermore, the bias against creativity interfered with participants’ ability to recognize a creative idea. These results reveal a concealed barrier that creative actors may face as they attempt to gain acceptance for their novel ideas.


Obama's Jobs Bill: A Reasonable Plan

Here are some quick thoughts on President Obama’s jobs plan:
– It’s reasonably big, at about 3% of GDP.
– It’s reasonably front-loaded. Goldman Sachs says it will raise 2012 GDP by about 1.5%–before any multiplier effects. Moody’s chief economist Mark Zandi thinks the effect on 2012 GDP will be about 2%. Expect more estimates in the 1-3% range for 2012; smaller for 2013.
– It’s reasonably well targeted. Unemployment insurance extensions will get spent. Infrastructure money gets spent and also builds stuff. as for the payroll tax: Who knows if it gets spent, but the point is to stimulate hiring, rather than spending.
– It’s reasonably well designed. The biggest problem with a payroll tax is that firms get it even for employees already on the books. But this time, the biggest payroll tax cut is only for firms raising their payrolls. This will yield a much bigger bang-for-each-buck. Early analyses have yet to realize how important this is.

Who First Said, "Great Scott!"? And Who Is Scott?

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
Bill asked:

“Great Scott!
As in, I’d love to know the origin of the phrase made famous most recently by Christopher Lloyd’s zany character in the Back to the Future series, but also used with some frequency much earlier by Hank Morgan, Mark Twain’s own Connecticut Yankee.”

Garson O’Toole, creator of the fantastic quoteinvestigator.com site, has found the earliest known example of the exclamation “Great Scott!” in The Eclectic Medical Journal, December 1856:


Day After the Debate: Intrade Odds of Republican Candidates Securing Presidential Nomination

Today, it seems that everyone has their own opinion on who helped themselves and who didn’t in last night’s Republican presidential candidates’ debate. And consensus is hard to come by, even in the same news room.
Take the Washington Post, for example. On its PostPartisan blog, first Richard Cohen wants us to think that Rick Perry was the “Big Loser” of the night. But then 90 minutes later, his colleague Marc Thiessen weighs in saying that Perry “had a very good night.” Rather than relying on Beltway journalists to decide won and who lost, I figured: why not see what the market is saying? So I headed over to Intrade to take a look at the odds for who will wind up as the 2012 Republican Presidential Nominee.
It does appear that Perry is slipping after last night’s debate. Even in the time it took me to put this blog post together, he’s lost a percentage point, going from 37.5% to 36.4%. While Mitt Romney has remained even so far today at 36.3%. These markets are of course fluid, but here’s a snapshot of the current Intrade odds for each candidate at last night’s debate, and how they’ve moved over the last week.


Baby Talk: The Benefits of Bilingualism

To all you new parents out there: if you’re trying to decide whether to spring for that Mandarin-speaking nanny, the answer is yes. Signing up your child for Chinese language kindergarten classes will be far too late.
A study in the Journal of Phonetics about bilingual learning offers new insight into babies and their relationship to the spoken word. Researchers at the University of Washington’s Institute for Learning & Brain Sciences compared the brain functions of babies raised in a monolingual household to those raised in a bilingual household, and found that bilingual babies are more likely to maintain their language learning ability for a longer period of time.


A Freakonomics-inspired Novel

We recently got an email from Michael Klein, an economics professor at Tufts who’s currently on leave as chief economist at the Office of International Affairs at the U.S. Treasury. Klein, it turns out, has done the rarest of things: turned the dismal science (economics) into fodder for a humorous work of fiction. His new novel is called Something for Nothing. Klein wrote to tell Dubner and Levitt that the novel was (at least partly) inspired by Freakonomics. Quoting from his email:

At the center of its plot is a Freakonomics-like result that a young professor publishes which promises to launch his career (it concerns the efficacy of teenage abstinence programs – this is one meaning behind the book’s title).
…The novel’s focus is the challenges facing a young professor who faces tradeoffs in work vs. personal life, and intellectual integrity vs. career advancement.

Thanks for writing Michael, and good luck with the book!


How Are Sharks Less Dangerous than Vending Machines? An Exercise in Conditional Risk

Did you know that vending machines, not a major danger in most of our minds, are twice as likely to kill you as a shark? I heard this statistic at the new shark-and-ray touch tank of the New England Aquarium, which I try to visit weekly with my daughters. You stand at a large, shallow tank with plexiglass walls and can lay your hand in the water, gently feeling the sharks and sting rays swimming by.
The aquarium probably wants to convince visitors that sharks are not the fierce predators of Jaws fame, and thereby help protect sharks from hunting and extinction. Although I could admire this motive, the comparison always surprised me. My number sense complained that sharks simply must be more dangerous than vending machines.
However, upon looking up the risks, I found that the comparison was correct. The yearly risk (in the United States) of dying from a shark attack is roughly 1 in 250 million. In contrast, the yearly risk of dying from a vending machine accident is roughly 1 in 112 million. The vending machine is indeed roughly twice as lethal as the shark!
Why then was I still troubled by the comparison? Maybe my number sense needed a tune up, and I should just accept the statistical facts of life. I then started thinking about it using the method of easy cases.
