It hurts more from a man
For a given amount of pressure, it hurts more when a man is making you feel bad:
Participants placed a finger in a clamp which was tightened using a pressure gauge until they reported feeling pain. Both men and women appeared to feel pain more quickly if the person turning the clamp was a man.
Previous studies have shown that men report feeling less pain in front of a female experimenters – but this was put down to their wanting to appear more macho.
David Williams, who carried out the study at the University of Westminster in the UK, says his findings contradict this assumption. Williams suggests that the subjects of his study may be socially conditioned to expect men to be more likely to inflict harm. The effect, “is likely to be a result of what participants subconsciously expect, based on socially acquired gender stereotypes,” he says.
We are susceptible to the power of suggestion in other ways as well:
The study also shows that a person’s surroundings can affect their sensitivity to pain. Objects that might be associated with suffering – such as a chart showing wounds or a poster related to blood donations – were found to make the participants report feeling pain more readily.
Here is the full story, here is the researcher.
The bottom line? No, it is not all in your head. Nonetheless a stoic attitude may help you endure discomfort. Furthermore we seem programmed to think that men are the bad guys. They usually are.
Loan markets in grades
A school in China is allowing students who don’t do well in tests to borrow a few extra marks as long as they pay them back with interest.
The scheme was recently introduced by Penglai Road No 2 Primary School in the Huangpu District of Shanghai, reports Xinhua.
Students who do poorly on a test can ask their teachers to lend them a few points to improve their grade, but twice as many points must be paid back on the next test, assuming they achieve a better mark.
If they don’t, interest on the loan continues to run at 100% per test until it is paid off.
It is reported that about 40% of students at the school have taken out such loans.
Why the monopoly provision? If you are going to do this at all, allow students to trade and lend points among themselves, thereby establishing a competitive equilibrium price.

The APA (American Philosophical Association) is looking for stories about how valuable philosophical training has been to people other than professional, full-time philosophers.
Here is the full story. And here is an excerpt from an accompanying letter:
We might also use some of these names later in a fund drive we are now planning.
Good luck is all I can say. If you can think of anyone since Alcibidiades and Alexander the Great, let them know. Queen Christina did study with Rene Descartes, and John Stuart Mill sat in Parliament, but no U.S. example comes to mind. Might philosophy be best suited to advising an autocrat?
Addendum: Astute reader Brock Sides offers the following link to famous philosophy majors. The list includes Woody Allen, Iris Murdoch, David Foster Wallace, Bill Clinton, the Pope, Harrison Ford, Bruce Lee, and Mike Schmidt.
Markets in everything, part II
You can now buy a personalized romance novel, featuring you and your sweetheart:
To get their names in print, customers decide on a book – most companies offer several stories to choose from – then fill out a questionnaire with details such as their love’s hair color and nickname. The information is inserted into the context of pre-fab story and presto, a personalized romance.
Don Fox of Port Saint Lucie, Fla., bought the novel “Treasure Seekers” for his wife last Valentine’s Day and included details such as the type of car he drives and his wife Josephine’s favorite radio station in the text.
“It’s something my wife and I will have forever. It’s unique,” said Fox, 43. “If you get a box of chocolates, it looks just like the box you got before that one. Then you eat it and it’s gone.”
The novels come in “mild” and “wild” versions and the plots take place in various standard romance novel locales such as a dude ranch and the white sand beaches of Tahiti (search). While their text won’t win any Pulitzer Prizes, they offer a quick read and, at $55.95, the books won’t break the bank.
Some people actually like this idea:
“It was an addictive read because it makes you the star,” said Pete Hart, 34, who received a pre-fan novel called “Vampire Kisses” from his girlfriend. “I was referred to as Pedro in the book, which is my nickname. I found that quite charming.”
Another fellow noted:
“It read more like a novel or novelette and less like a typical romance novel,” he said. “I enjoyed reading it. Besides, I was in it.”
So what is next? How about DVD movies with your face superimposed upon that of Tom Cruise?
But our world is not always taking steps forward. Ebay has been moving to take down sales of imaginary girlfriends.
If you are curious, here is part one of “Markets in everything.”
What is the world’s longest direct commercial flight?
The new Los Angeles to Singapore route, eighteen hours, forty minutes, courtesy of Singapore airlines.
Next, not surprisingly, is Singapore to Los Angeles, although it is a full two hours, forty minutes shorter, because of air currents. Then comes New York to Hong Kong, sixteen hours.
Here is an article on how people stand it. Some sleep, some drink, and some argue politics with their seatmates. Airlines are now taking a hand in shaping on-board community. Virgin will be installing in-flight instant messaging on some of its longer flights, to encourage the formation of small discussion groups on the plane.
How about me?: I view any flight (that’s the flight, not the waiting) under six hours as a benefit, not a cost. It is a chance to do sustained reading and thinking without interruption. A ten hour flight remains tolerable if I have enough leg room. I need a stack of good books, some chocolate, and an assortment of cheeses. After ten hours my reading starts to veg out. But even then I would prefer in-flight institutions that tax people who try to communicate with me.
Addendum: Air genius Gary Leff informs me that a forthcoming NY-Singapore route, Singapore Air, will soon become the world’s longest direct flight.
Is “mindsight” a sixth sense?
Some people may be aware that a scene they are looking at has changed without being able to identify what that change is. This could be a newly discovered mode of conscious visual perception, according to the psychologist who discovered it. He has dubbed the phenomenon “mindsight”.
Ronald Rensink, based at the University of British Columbia in Canada, showed 40 people a series of photographic images flickering on a computer screen. Each image was shown for around a quarter of a second and followed by a brief blank grey screen. Sometimes the image would remain the same throughout the trial; in other trials, after a time the initial image would be alternated with a subtly different one.
n trials where the researchers manipulated the image, around a third of the people tested reported feeling that the image had changed before they could identify what the change was. In control trials, the same people were confident that no change had occurred. The response to a change in image and control trials was reliably different.
Our visual system can produce a strong gut feeling that something has changed, Rensink says, even if we cannot visualise that change in our minds and cannot say what was altered or where the alteration occurred.
Here is the full story. The bottom line? Maybe somebody really is following you, and subtly changing small items in your environment.
Milton Friedman opposes drug reimportation
Read this TCS interview. He also blames the whole mess on the FDA, whose regulations have raised the costs of drug development to about $800 million per drug.
If you could only learn five things…
Yana, who is fourteen, was complaining last night about her math homework, and about calculus in particular. Without much thinking, I responded that if you could only learn five things from schooling, calculus should be one of them. First came an “Ugh.” Then came a question:
“What are the other four?”
Without much thinking, here was my list, in no particular order:
1. Calculus
2. Statistics
3. Programming
4. Shakespeare
5. The Bible
Another Ugh, directed mostly at the first three items. Writing would have been a natural sixth pick, and would not have drawn an ugh either.
Addendum: I’ve already received several emails asking why I chose the Bible rather than microeconomics. I didn’t mean anything sectarian in my choice of the Bible, rather it is a critical foundation of Western civilization and of Western literature. Plato would be next in line. As for microeconomics, knowing it brings huge social benefits but the private benefits are less clear. I love life as an economist, but it is not for everyone.
Protectionism hurts fine dining
My biggest personal complaint with U.S. trade policy concerns non-pasteurized cheese. Read Fred Foldvary:
Few Americans know what really good cheese tastes like, because the U.S. government bans tasty handmade cheese made from untreated milk. The U.S. Food and Drug Administration prohibits the sale of cheese made with raw milk, which has not been aged for 60 days. If the raw-milk cheese is from France, voila, its sale is prohibited in the USA no matter how long it has been aged.
The danger of eating raw-milk cheese is similar to that of eating raw oysters, yet the latter is legal in the US. Those with higher risk of infection, such as pregnant women, should not eat raw-milk cheese, raw oysters and steak, and other foods that can harbor microbes that cause diseases. But Europeans have been eating raw-milk cheeses since ancient times, evidently with little ill effect. European cheese makers are generally careful to keep the milk uncontaminated, which minimizes the risk.
Now I have a new grudge: the ban on Szechuan peppercorns.
Since 1968, the federal government has banned the import of Sichuan peppercorns, which are the dried berries of the prickly ash shrub. The Agriculture Department did not really enforce the ban until two years ago, and its effort is expected to dry up supplies soon. Some chefs and retailers say that they are unable to find the peppercorns, which are often an ingredient of five-spice powder, a common Chinese seasoning. Others say they are selling what was stockpiled before the enforcement effort began.
The details are a bit complicated, but if you can believe the NYT, there is no good reason for the ban other than excessively broad bureaucratic classifications (a related item endangers citrus crops).
You can’t cook Sichuan food without huajiao,” said Wang Dinggeng, the chef at Grand Sichuan International on Second Avenue. “You can’t get that special ma la flavor,” he said of the peppercorns’ numbing (ma) and burning (la) effects.
Tragic, I say, tragic. By the way, if you ever visit my university, make sure you eat at the Szechuan restaurant China Star, in Fairfax, on Rt.236. Get the house specials, before it is too late.
Googling the Great Books
Google is scanning everything pre-1923 in the Stanford Library into its system, read Will Wilkinson. Here’s to hoping that Congress does not extend the term of copyright protection once again.
Are classical recordings disappearing?
Norman Lebrecht recently predicted that the year 2004 would be the last for the classical recording industry. To be sure, the number of new releases is declining and major orchestras are losing their recording contracts, read this New York Times story.
David Hurwitz offers some good points in response. Naxos of course is thriving. Classical music is cheaper than ever before and many of the recordings are excellent. Try my favorite version of the Scriabin piano sonatas, by Bernd Glemser.
Furthermore classical indepedent labels continue to bring innovative new releases to the market:
Over the past decade, and thanks to labels like Naxos, BIS, Hyperion, Ondine, CPO, Harmonia Mundi, Chandos and others, music lovers have learned that the quality of music making today is generally so high that excellence may be found well beyond the cloistered catalogs of the major labels. Their classical divisions are dying because they are no longer necessary: the myth of their uniqueness and monopoly on great performances has been exploded forever. That’s the reality of the classical music recording industry at present. It’s also reason for optimism, not despair, because while the majors may or may not survive depending on their adaptability, excellent music making will continue to thrive and reach the public via the classical recording industry, whatever its actual form.
I’ve found the last year to be wonderful for new releases of Elliott Carter, Helmut Lachenmann, Pierre Boulez, and John Cage. Minority tastes, to be sure, but the slow sellers are usually the first to go if the sector is truly dying.
Here are some off the cuff predictions for the future of the music industry:
1. The lines between classical and other genres, most of all world music, will blur increasingly.
2. The next generation of classical composers will come from Asia, where classical music remains a living art.
3. World music will continue to grow in importance. These artists learned how to live without copyright protection long ago.
4. Given the commercial prominence of the DVD, we can expect soundtrack music to grow in importance and quality.
5. Classical CDs will be custom-made to order, rather than “released,” see the NYT article for more detail.
In sum: The new musical world won’t look much like the old, but I have yet to see convincing reasons for pessimism. I don’t buy so many classical CDs any more, in part because I already have a dozen or more copies of each Beethoven piano sonata, and three copies of Messiaen’s major works for organ. Let’s not confuse “good for the suits” with “good for the consumer.”
More common sense on outsourcing
Computer programmers are a highly paid lot in the United States. Both the U.S. and India would be better off if lower-wage Indians did more of the programming and the U.S. did more innovating. Read here about tech executive Marc Andreesen, who is willing to come out and offer three cheers for outsourcing. Here is my previous post on outsourcing.
Did sexual selection make humans brainy and artistic?
Birds sing to attract mates, so what about humans? Are our jokes, stories, guitar strumming just part of an elaborately programmed mating strategy? We all know how much young girls fall for rock stars. Here are three reviews of Geoffrey Miller’s The Mating Mind. Click here for a good summary and short critique, here for an outright critique, and here for an account of why Miller’s views are not always so popular.

The economics of Netflix
Lately I’ve signed up for Netflix.com. You pay $20 a month and you get mail order DVDs, free shipping, and you can keep them as long as you want. The limit is three to a customer. Once you return what you have, you can order some more. This is a big business and Wal-Mart is entering the market.
I am finding that Netflix changes what I watch. Service is prompt but there is a lag between ordering and viewing. The only late fee is the rather abstract opportunity cost of not being able to order more films. So I can order a DVD and not watch it for a week or even a month. I can engage in a kind of artistic deficit spending. I find myself ordering more movies that I feel I “ought to watch,” but won’t necessarily enjoy. After all, the consequences of my decision lie further in the future. I find myself especially altruistic toward my wife, and what she wants to watch. I am more willing to order long movies. I could never bring myself to rent The Shawshank Redemption, which is compelling yet sappy and well over two hours long, but now I have seen it.
Netflix reminds me just the tiniest bit of democratic voting. I order films to feel good now about my ordering, and not necessarily to watch them. Overall Netflix has improved my movie viewing and induced me to experiment more. Fortunately it is a supplement to other ways of choosing movies. When it comes to what I really want to see, nothing beats getting in the car and driving there, pushing through the yellow light to make sure I don’t miss the previews.
Does free trade lead to insufficient diversification?
The theory of comparative advantage, and the theory of increasing returns, both predict that free trade brings specialization. Michigan and Tennessee produce automobiles, but Delaware does not. I have heard free trade critics suggest that regions end up especially vulnerable and overspecialized.
Yes in economics virtually everything is possible, once you recognize that Giffen goods and upward-sloping demand curves cannot be ruled out. But I am not so worried about free trade leading to excess specialization.
First, individuals can buy equities from multiple regions or countries. There does appear to be an inefficient “home bias” when it comes to investing, but surely free trade is not at fault here. If anything, free trade should encourage investors to think more globally and to diversify more.
Second, individuals specialize, in response to trade, because specializing brings higher returns. When investors expand a firm or line of business they internalize risk-return trade-offs.
Third, we must consider global risk. Let us say that protectionism helps a country avoid a declining industry. The world as a whole does not gain. Those economic problems are simply shouldered by another country, and in a less efficient way, relative to free trade.
Fourth, risk is borne by individuals, not by countries per se. Having many different industries in a country does not by itself create safety for individual investors or workers. Who cares if France has its own movie industry, if you are losing your job in computer software? Contrary to what Dana Rodrik suggests, it is not necessarily economically safer to live in a large country.
I can see a potential political version of the argument. Free trade, by inducing specialization, might make tax revenue more volatile in a country. Still, tax revenue should be higher in absolute terms. And if revenue volatility is a problem, I would prefer fiscal responsibility over protectionism as the proper medicine.
I am indebted to Randall Parker and Arnold Kling for sharing some of their email correspondence on this topic with me.
