The Perils of Popularity, or: How Is a Frozen Website Like a Sick Person?

It is hard to predict, in nearly every pursuit, what will be popular and what will not. Blog posts are no exception. Sometimes a blogger posts something that would seem to generate a lot of interest and it fades without a trace; sometimes you post something that seems like no big deal and, for whatever reason, people care a lot. . . .



Stay Off the Internets If You Know What’s Good for You

New Jersey governor Jon Corzine, unhappy with an official probe into the e-mails he sent to a former girlfriend who was also the state union president, has decided to swear off e-mail entirely. (In related news, stocks in smoke-signaling firms surged in overnight trading.) Meanwhile, Whole Foods CEO John Mackey has also found that old online exchanges can come back . . .



And Today Is…

July 12 is Different Colored Eyes Day, celebrating both “diversity of eye color” and Heterochromia, a condition in which a person’s eyes are different colors. Should genetic engineering become widely available, traits like eye color could cease to become inherited traits, a development that critics cite as a danger to society.



Nigerian Oil Spam Meets “Three Kings”

My spam filter is so good that I barely ever get to see all the Nigerian oil-scam spams any more. But this one poked its way through today. It is always nice to see people thinking creatively. My name is Sgt Kenny Baker, Jr. I am in the Engineering military unit here in Ba’qubah in Iraq, we have about $10, . . .



The False Altruism of Alumni Giving

Can a charitable act truly be called charitable when the contributor wants or expects a reward? In a new study, Princeton economics professor Harvey Rosen and Stanford graduate student Jonathan Meer examined this question using a specific case of incentivized charity: alumni donations. They found that the size and frequency of an alumnus’s contributions to his alma mater rise in . . .



And Today Is…

July 11 is National Cheer Up The Lonely Day, an increasingly necessary task according to the National Science Foundation General Social Survey, which found that Americans are more socially isolated then in previous decades despite (or because of?) the growth of communications technology.



The FREAKest Links: Two’s A Crowd Edition

Fortune Small Business reports that a feud is brewing between two companies that provide inflatable torsos to serve as movie extras in crowd scenes. Industry leader Inflatable Crowd is being sued by competitor Crowd in a Box over patent infringement, while the defendant’s owner claims he came up with the idea on his own. (Hat tip: the Wall Street Journal‘s . . .



Consider the Source?

I’m reading a pretty interesting book called Blue Blood. It’s a memoir written a few years back by a Harvard-educated New York City cop Edward Conlon (who also wrote the New Yorker’s “Cop’s Diary” column under the name Marcus Laffey). I have the paperback edition, which means that the first three or four pages are devoted to positive reviews and . . .



If Public Libraries Didn’t Exist, Could You Start One Today?

Raise your hand if you hate libraries. Even though this blog doesn’t enable me to peer through the screen into your living room (yet), I am guessing there aren’t a lot of raised hands out there. Who could possibly hate libraries? Here’s one guess: book publishers. I am probably wrong on this, but if you care about books, hear me . . .



In Praise of Ancient Technologies, and Aptonyms

There was an interesting article in the New York Times sports section the other day about how the All England Club has kept the Wimbledon tournament free of pigeons since 1999 by employing a man named Wayne Davis to bring in his small flock of peregrine falcons. Until Davis came along, the pigeons were a real nuisance. “In the old, . . .



And Today Is…

July 10 is Clerihew Day, marking the birth date in 1875 of Edmund Clerihew Bentley, the British writer who invested a four-line rhyming verse, usually biographical in nature and resembling a limerick, that came to be known as a “clerihew.” Bentley composed the first clerihew about Sir Humphrey Davy, the chemist credited with isolating and naming aluminum.



The FREAKest Links: Paper Beats Rock and Boys Named Hell Edition

As enduring fans of the sport, we were glad to hear that ESPN2 broadcast its first coverage of the 2007 USA Rock Paper Scissors League championship, which took place in May at the Las Vegas Mandalay Bay. The single-elimination competition was won by Jamie Langridge from Odessa, Texas, who employed a “complex adaptive” strategy to take home the Bud Light . . .



Born Under a Good Sign

This kid better have a great life, or he’s got a lot to answer for: a boy named Jack Falkner was born in Chippewa Falls, Wisc., on Saturday, 7/7/07, and he weighed 7 pounds, 7 ounces. That, at least, is what the hospital says. But think about it: if you were the person looking at Baby Jack’s scale, mightn’t you . . .



The Science of Large Breasts, and Other Evolutionary Verities

I blogged nearly a year ago about a study by the evolutionary psychologist Satoshi Kanazawa which argued that beautiful women sometimes marry unattractive men because of the following supply/demand gap: there are simply more good-looking women than there are good-looking men. One reason, Kanazawa said, is that beauty is a more valuable trait for a female, and is therefore accentuated . . .



Lead and Crime

Over the weekend, the Washington Post published an article suggesting that much of the decline in crime in the 1990s may have been due to the reduction of childhood lead exposure after the removal of lead from gasoline and house paint. This is an intriguing hypothesis. There is evidence on an individual level that high exposure to lead is harmful . . .



And Today Is…

July 9 marks the start of Nude Recreation Week, during which you are encouraged to do household chores, exercise or telecommute in the buff . Nudist vacation destinations are reportedly the travel industry’s fastest growing niche market, taking in more than $400 million a year.



Don’t Forget to Place Your Bets Tomorrow

Tomorrow’s date is 7/7/07. If you believe in lucky 7’s (the influence of which we’ve written about before), it’s a good day. During a recent trip to Las Vegas, I was told by one casino executive that never in the history of Vegas have the hotels been booked so far in advance as they are for tomorrow. I predict that . . .



The FREAKest Links: Smaller Homes, Free Burritos, and the Price of Death Edition

Bad news for retirees (and others) who want gigantic houses in Boulder, Colo.: local officials may enact home size restrictions. Under the proposal, residents would be allowed to build homes larger than 4,000 square feet only if they agree to invest in the preservation of agricultural or rural land in other regions. (Hat tip: J.C. O’Connell.) Here’s more on the . . .



Is This Lance Armstrong’s Year?

The wheels seem to have come off the Tour de France. This year’s race, with a ceremonial start in London, is of course absent the retired Lance Armstrong, whom Americans learned to love and the French grew to hate in seemingly direct proportion. But the race this year is also missing Floyd Landis, last year’s disgraced winner, as well as . . .



Obama Wants to Pay Teachers What They’re Worth

It sounds as if Barack Obama has been listening to some economists (maybe even Austan Goolsbee): he has come out in favor of merit pay for schoolteachers. From an A.P. article: Democratic presidential candidate Barack Obama told the largest teachers union Thursday that performance-based merit pay ought to be considered in public schools. Teachers at the National Education Association’s annual . . .



And Today Is…

July 6 is one woman’s self-declared National Fried Chicken Day. If you don’t like her recipes, Chef Jeff has a good one in his book. Do keep in mind that, according to the Center for Disease Control, national obesity rates have more than quadrupled since the 1970s.



Yet Another Job Opportunity for Economists

We’ve written in the past about the life-like struggles for resources and justice in online roleplaying games and universes. Now comes word that EVE Online, a sci-fi MMOG (Massively Multiplayer Online Game), has hired a full-time economist, Eyjólfur Guðmundsson, to help manage the game’s virtual economy. Insert your own joke. (Hat tip: Derek Guder)



The FREAKest Links: Terrorists, Phones, and Breast Exams Edition

Mirroring Levitt’s thoughts on doctors plotting terrorist attacks, the Wall Street Journal takes an in-depth look at Alan Krueger‘s findings that terrorists tend to come from high-income, high-education families. David Pogue of the New York Times points out that, in the midst of last week’s iPhone mania, most of us missed T-Mobile’s announcement of a new plan under which all . . .



A Q&A With Intrade’s John Delaney

Prediction markets. Are there any other two words that couple as nicely as those, at least to readers of this blog? The promise of a prediction market is simple and profound: if you ask a lot of people a question about politics or sports or Hollywood movies, and those people are motivated to answer it correctly, their collective judgment turns . . .




What Do a New Orleans Death Spike and a Study on Surplus Embryos Have in Common?

They were both widely reported this week, although not at ABC News. Gary Langer, who runs polling at ABC and also acts as its data cop, kept both stories off the air after kicking their tires and determining that they weren’t worth reporting. Langer was obviously not sufficiently consulted in the Paris–Hilton– gets-out-of-jail story.



And Today Is…

July 5 is National Workaholics Day. If you are reading this at a work computer, you know who you are. For those who feel they have a problem, Workaholics Anonymous has been growing throughout the country — though some chapters are foundering, given that so few people will leave work to make it to meetings.



What’s a W.A.S.H.?

Mike Bloomberg regularly calls himself a “short, Jewish billionaire from New York” … but how Jewish is he? Here’s an interesting article from the Forward on Bloomberg’s brand of Jewishness in which an acquaintance calls Bloomberg something I’d never heard, but which is a pretty useful acronym: W.A.S.H., or a White Anglo-Saxon Hebrew. If widely adopted, this would give headline . . .



Doctors on Suicide Bombing Missions? Not as Strange as It Seems.

So much for the Hippocratic Oath. The latest terror attacks in the United Kingdom were apparently carried out by doctors. The specifics of the case are admittedly bizarre, but the general principle that acts of terror are often committed by individuals with high levels of education is not at all unusual, a fact I learned from economist Alan Krueger‘s excellent . . .



And Today Is…

July 4, in addition to being a bona fide national holiday, is also Tom Sawyer Day in Monroe City, Missouri. The festivities include a 10K run – whether the race is considered work or leisure is for Mark Twain to decide.
