Why my mom didn’t buy me a slot car track for Christmas in 1978, even though I told her that’s what I wanted

Friday, December 15th, 2006

In Why my mom didn’t buy me a slot car track for Christmas in 1978, even though I told her that’s what I wanted, Dave Munger looks at a study of couples and how they predict each other’s taste:

Lerouge and Warlop recruited 35 couples to participate in the study. Each partner was placed in a separate cubicle for the duration of the study, and had no contact with his or her mate. They then were shown pictures of 30 different sets of bedroom furniture and asked to indicate their impression of it (positive or negative). The next part was the key to the study:

Each partner was shown 30 new furniture sets — the sets the other partner had already rated. In each case, they were asked to predict how another person would feel about the furniture. Half the participants were told they were predicting their own partner’s preference, and the other half were led to believe they were choosing for a stranger. In fact, all participants were predicting their own partner’s preferences. After each prediction, the partner’s actual preference was revealed, so as the study progressed, presumably each participant would better understand his or her partner’s preference, and gradually make better predictions.

Overall, participants were better at predicting their partners’ tastes when they believed they were predicting the tastes of a stranger. When they knew they were predicting their own partners’ tastes, the accuracy of predictions depended on how similar their own tastes were to that of their partners.

Here’s the key finding: When partners’ tastes were different from their own, then they were better at predicting each others’ tastes if they believed they were predicting the tastes of a stranger.
[...]
When you know someone well, it appears, you begin to assume they have the same tastes as you do.

World’s tallest man saves ailing dolphins

Friday, December 15th, 2006

This seems like something that should happen on a popular sitcom during sweeps week. World’s tallest man saves ailing dolphins:

Bao Xishun, the world’s tallest man, reaches in to retrieve objects from the stomach of a sick dolphin at an aquarium in Fushun, in China’s northern Liaoning province, Wednesday, Dec. 13, 2006. Bao, whose arms measure more than a meter in length, was called in by the aquarium after experts failed to surgically remove unidentified objects from the stomachs of two dolphins. Bao was able to reach in and retrieve the objects, which turned out to be pieces of plastic from their pool surround. Despite a few remaining small pieces of plastic in their stomachs, local experts expect the dolphins to recover soon. The 2.36 meter-tall Bao was confirmed as the world’s tallest man by the Guinness Book of Records in 2005.

Dictatorships and Double Standards

Friday, December 15th, 2006

In 1979, Jeane Kirkpatrick spoke of Dictatorships and Double Standards — in Iran, Nicaragua, and the rest of the world:

In each of these countries, the American effort to impose liberalization and democratization on a government confronted with violent internal opposition not only failed, but actually assisted the coming to power of new regimes in which ordinary people enjoy fewer freedoms and less personal security than under the previous autocracy — regimes, moreover, hostile to American interests and policies.

The pattern is familiar enough: an established autocracy with a record of friendship with the U.S. is attacked by insurgents, some of whose leaders have long ties to the Communist movement, and most of whose arms are of Soviet, Chinese, or Czechoslovak origin. The “Marxist” presence is ignored and/or minimized by American officials and by the elite media on the ground that U.S. sup- port for the dictator gives the rebels little choice but to seek aid “elsewhere.” Violence spreads and American officials wonder aloud about the viability of a regime that “lacks the support of its own people.” The absence of an opposition party is deplored and civil-rights violations are reviewed. Liberal columnists question the morality of continuing aid to a “rightist dictatorship” and provide assurances concerning the essential moderation of some insurgent leaders who “hope” for some sign that the U.S. will remember its own revolutionary origins. Requests for help from the beleaguered autocrat go unheeded, and the argument is increasingly voiced that ties should be established with rebel leaders “before it is too late.” The President, delaying U.S. aid, appoints a special emissary who confirms the deterioration of the government position and its diminished capacity to control the situation and recommends various measures for “strengthening” and “liberalizing” the regime, all of which involve diluting its power.

The emissary’s recommendations are presented in the context of a growing clamor for American disengagement on grounds that continued involvement confirms our status as an agent of imperialism, racism, and reaction; is inconsistent with support for human rights; alienates us from the “forces of democracy”; and threatens to put the U.S. once more on the side of history’s “losers.” This chorus is supplemented daily by interviews with returning missionaries and “reasonable” rebels.

As the situation worsens, the President assures the world that the U.S. desires only that the “people choose their own form of government”; he blocks delivery of all arms to the government and undertakes negotiations to establish a “broadly based” coalition headed by a “moderate” critic of the regime who, once elevated, will move quickly to seek a “political” settlement to the conflict. Should the incumbent autocrat prove resistant to American demands that he step aside, he will be readily overwhelmed by the military strength of his opponents, whose patrons will have continued to provide sophisticated arms and advisers at the same time the U.S. cuts off military sales. Should the incumbent be so demoralized as to agree to yield power, he will be replaced by a “moderate” of American selection. Only after the insurgents have refused the proffered political solution and anarchy has spread throughout the nation will it be noticed that the new head of government has no significant following, no experience at governing, and no talent for leadership. By then, military commanders, no longer bound by loyalty to the chief of state, will depose the faltering “moderate” in favor of a fanatic of their own choosing.

How the Public School System Crushes Souls

Friday, December 15th, 2006

Steve Olson explains How the Public School System Crushes Souls — or, at least, how it crushed his soul:

My father is an autodidact engineer. We had computers (TRS-80) and teletypes in our home since 1977. I taught myself to program Level II Basic at eight years old. By 10, I was hacking into commercial programs to improve them. By 11, I was enrolled and succeeding in college level programming classes at North Dakota State University.

Two years later in Jr. High, I took an Apple II computer class. On the first day of class, I looked through the syllabus, found the last lesson, loaded the 5 1/4 inch floppy, and completed it. I beamed with pride and arrogance. The teacher looked at my program, turned bright red, yanked me out of my seat by my ear, and I fell to the floor humiliated. He pointed to the door and said, “get out of my classroom.” He forced me to sit in the hall the rest of the semester and failed me.

The superlions marooned on an island

Wednesday, December 13th, 2006

A new documentary, Relentless Enemies, tells the story of superlions marooned on an island:

“We discovered this tiny sandy island in the Okavango,” says Dereck. “It is extraordinary because it became totally isolated from the mainland 15 years ago when the course of the river changed, and a huge herd of buffalo and lions were trapped on a piece of land measuring 200 square kilometres.”

Through this twist of geographical fate, these two ancient species are now engaged in a desperate battle of survival — watched by six bemused refugee wildebeest and a handful of similarly outnumbered warthogs.

Thus, the island has become a unique, ecological experiment. In order to exist without the customary spectrum of weaker African prey like zebra, giraffe and impala, the Duba lions have had to develop distinct strategies in order to trap the single available food source.

They have adapted to this challenge by hunting during the day under the baking African sun, swimming through deep rivers in the hunt for buffalo. This water-based training programme combined with a diet of protein-rich buffalo meat has led to the development of huge muscles, and these super-cats now dwarf other lions.

The island lions also use highly advanced psychology in their quest for food, predicting the course of the buffaloes’ daily trek by anticipating their need for water — then lying in wait at the precise spot along the river where the herd will eventually stop for refreshment.

In turn, the buffalo have responded to the threat by merging into a vast mega-herd of 1,200 beasts — five times the size of a normal group. They have also, at times, turned on the lions, killing isolated cubs.
[...]
A subspecies is emerging which the experts have named the Duba swamp lion — as opposed to the jungle lion, the desert lion, or the lion of the mainland African plain. It is distinctive in appearance, with a bigger, thicker neck and an extra-strong chest. The lionesses are almost the same size as the male lions on the Botswana mainland.

Has science fiction influenced your work?

Wednesday, December 13th, 2006

Discover magazine asked Marvin Minsky, Has science fiction influenced your work?:

It’s about the only thing I read. General fiction is pretty much about ways that people get into problems and screw their lives up. Science fiction is about everything else.

Do Helping Professions Help More?

Wednesday, December 13th, 2006

Alex Tabarrok says that Robin Hanson has his Scrooge hat on when he asks, Do Helping Professions Help More?:

A student told me the other day he wanted to be a doctor, so he could help people. I thought, “What, as opposed to the rest of us who hurt people?” Contrary to the smug self-righteousness assumptions of those in “helping” professions, like child care, teaching, counseling, or emergency services, it is far from obvious that these professions are any more helpful than the rest.

All but Ageless

Wednesday, December 13th, 2006

Turtles are All but Ageless:

With its miserly metabolism and tranquil temperament, its capacity to forgo food and drink for months at a time, its redwood burl of a body shield, so well engineered it can withstand the impact of a stampeding wildebeest, the turtle is one of the longest-lived creatures Earth has known. Individual turtles can survive for centuries, bearing silent witness to epic swaths of human swagger. Last March, a giant tortoise named Adwaita said to be as old as 250 years died in a Calcutta zoo, having been taken to India by British sailors, records suggest, during the reign of King George II. In June, newspapers around the world noted the passing of Harriet, a Galapagos tortoise that died in the Australia Zoo at age 176 — 171 years after Charles Darwin is said, perhaps apocryphally, to have plucked her from her equatorial home.

Behind such biblical longevity is the turtle’s stubborn refusal to senesce — to grow old. Don’t be fooled by the wrinkles, the halting gait and the rheumy gaze. Researchers lately have been astonished to discover that in contrast to nearly every other animal studied, a turtle’s organs do not gradually break down or become less efficient over time.

Dr. Christopher J. Raxworthy, the associate curator of herpetology at the American Museum of Natural History, says the liver, lungs and kidneys of a centenarian turtle are virtually indistinguishable from those of its teenage counterpart, a Ponce de Leonic quality that has inspired investigators to begin examining the turtle genome for novel longevity genes.

“Turtles don’t really die of old age,” Dr. Raxworthy said. In fact, if turtles didn’t get eaten, crushed by an automobile or fall prey to a disease, he said, they might just live indefinitely.

Turtles have the power to almost stop the ticking of their personal clock. “Their heart isn’t necessarily stimulated by nerves, and it doesn’t need to beat constantly,” said Dr. George Zug, curator of herpetology at the Smithsonian Institution. “They can turn it on and off essentially at will.”

Turtles resist growing old, and they resist growing up. Dr. Zug and his co-workers recently determined that among some populations of sea turtles, females do not reach sexual maturity until they are in their 40s or 50s, which Dr. Zug proposes could be “a record in the animal kingdom.”

Orphaned Squirrel Monkey

Wednesday, December 13th, 2006

Today’s dose of cute comes from an Orphaned Squirrel Monkey named Loki — an excellent name for a monkey, by the way:

Orphaned squirrel monkey Loki clings to his toy duck at Taronga Zoo in Sydney, Australia, in this Jan. 19, 2006, file photo. Loki, who lost his mother shortly after birth eight weeks ago, has been hand raised by zoo staff and will be introduced to the rest of the Squirrel Monkey’s when once he is weaned and learns to regulate his body temperature.

Where The Wild Things Are

Are we trying to reach the wrong goal in Iraq?

Monday, December 11th, 2006

Mitch Townsend asks, Are we trying to reach the wrong goal in Iraq?:

We went into Iraq with the goal of creating a democracy where a tyrant had ruled. After a few hundred years of democratic republics, constitutional monarchy, free markets, individual rights, and a tendency toward egalitarianism, we may have come to miss some of the obvious factors that make for a successful nation. It seems so natural to us that we may have imagined it to be the normal, default setting for any society; any instance of tyranny must be due to some interference with the natural progress of freedom, and the removal of that interference would allow that progress to resume.
[...]
Paradoxically, people establish a democratic republic because they understand that so much is at stake, but a democratic republic cannot function unless very little is at stake. A party or a person must be exposed to the real possibility of defeat in elections, and if voted out of office, must leave quietly and with as much grace as can be managed. This is only possible because the change in office will not result in show trials, disappearances, confiscations, and mass graves. We have to trust each other to an extraordinary extent, and we have to deserve the trust of each other.

There is not much mutual trust in Iraq.

Against organic farming

Monday, December 11th, 2006

Tyler Cowen cites a passage (from Voting with your trolley) against organic farming:

Perhaps the most eminent critic of organic farming is Norman Borlaug, the father of the “green revolution”, winner of the Nobel peace prize and an outspoken advocate of the use of synthetic fertilisers to increase crop yields. He claims the idea that organic farming is better for the environment is “ridiculous” because organic farming produces lower yields and therefore requires more land under cultivation to produce the same amount of food. Thanks to synthetic fertilisers, Mr Borlaug points out, global cereal production tripled between 1950 and 2000, but the amount of land used increased by only 10%. Using traditional techniques such as crop rotation, compost and manure to supply the soil with nitrogen and other minerals would have required a tripling of the area under cultivation. The more intensively you farm, Mr Borlaug contends, the more room you have left for rainforest.

You should also question the environmental benefits of local food production:

The DEFRA report, which analysed the supply of food in Britain, contained several counterintuitive findings. It turns out to be better for the environment to truck in tomatoes from Spain during the winter, for example, than to grow them in heated greenhouses in Britain. And it transpires that half the food-vehicle miles associated with British food are travelled by cars driving to and from the shops. Each trip is short, but there are millions of them every day. Another surprising finding was that a shift towards a local food system, and away from a supermarket-based food system, with its central distribution depots, lean supply chains and big, full trucks, might actually increase the number of food-vehicle miles being travelled locally, because things would move around in a larger number of smaller, less efficiently packed vehicles.

Research carried out at Lincoln University in New Zealand found that producing dairy products, lamb, apples and onions in that country and shipping them to Britain used less energy overall than producing them in Britain. (Farming and processing in New Zealand is much less energy intensive.)

How Art Can Be Good

Monday, December 11th, 2006

In How Art Can Be Good, Paul Graham argues that there is such a thing as good art; it’s not all “equally valid”:

When I was in art school, we were looking one day at a slide of some great fifteenth century painting, and one of the students asked “Why don’t artists paint like that now?” The room suddenly got quiet. Though rarely asked out loud, this question lurks uncomfortably in the back of every art student’s mind. It was as if someone had brought up the topic of lung cancer in a meeting within Philip Morris.

“Well,” the professor replied, “we’re interested in different questions now.” He was a pretty nice guy, but at the time I couldn’t help wishing I could send him back to fifteenth century Florence to explain in person to Leonardo & Co. how we had moved beyond their early, limited concept of art. Just imagine that conversation.

Examining the Libertarian Vote in Depth

Monday, December 11th, 2006

David Kirby and David Boaz have been Examining the Libertarian Vote in Depth:

In our study, “The Libertarian Vote,” we analyzed 16 years of polling data and found that libertarians constituted 13 percent of the electorate in 2004. Because libertarians are better educated and more likely to vote, they were 15 percent of actual voters.

Libertarians are broadly defined as people who favor less government in both economic and personal issues. They might be summed up as “fiscally conservative, socially liberal” voters.

In the past, our research shows, most libertarians voted Republican — 72 percent for George W. Bush in 2000, for instance, with only 20 percent for Al Gore, and 70 percent for Republican congressional candidates in 2002. But in 2004, presumably turned off by war, wiretapping, and welfare-state spending sprees, they shifted sharply toward the Democrats. John F. Kerry got 38 percent of the libertarian vote. That was a dramatic swing that Republican strategists should have noticed. But somehow the libertarian vote has remained hidden in plain sight.

This year we commissioned a nationwide post-election survey of 1013 voters from Zogby International. We again found that 15 percent of the voters held libertarian views. We also found a further swing of libertarians away from Republican candidates. In 2006, libertarians voted 59-36 for Republican congressional candidates — a 24-point swing from the 2002 mid-term election. To put this in perspective, front-page stories since the election have reported the dramatic 7-point shift of white conservative evangelicals away from the Republicans. The libertarian vote is about the same size as the religious right vote measured in exit polls, and it is subject to swings more than three times as large.

Based on the turnout in 2004, Bush’s margin over Kerry dropped by 4.8 million votes among libertarians. Had he held his libertarian supporters, he would have won a smashing reelection rather than squeaking by in Ohio.

President Bush and the congressional Republicans left no libertarian button unpushed in the past six years: soaring spending, expansion of entitlements, federalization of education, cracking down on state medical marijuana initiatives, Sarbanes-Oxley, gay marriage bans, stem cell research restrictions, wiretapping, incarcerating U.S. citizens without a lawyer, unprecedented executive powers, and of course an unnecessary and apparently futile war. The striking thing may be that after all that, Democrats still looked worse to a majority of libertarians.

Because libertarians tend to be younger and better educated than the average voter, they’re not going away.

Another interesting stat:

One more bit from our post-election Zogby poll: We asked voters if they considered themselves “fiscally conservative and socially liberal.” A whopping 59 percent said they did. When we added to the question “also known as libertarian,” 44 percent still claimed that description. That’s too many voters for any party to ignore.

C-130 Deploying It’s "Angel Decoy"

This footage of a C-130 Deploying It’s “Angel Decoy” seems like something out of the latest X-Men flick.

(That means it’s pretty cool looking.)
