Weekend Roundup

roundup4On Monday, we talked about what women want (hint: they prefer larger, and we’re not talking about wallets).

On Tuesday, we talked about beautiful folk songs; thanks to those who pointed me in new directions.

On Wednesday, we asked why job growth has been so sluggish compared to previous recessions.

On Thursday, I linked to a remarkably thoughtful and literate Fox News clip on immigration policy, featuring the fiery Don Boudreaux.

And on Friday, we lamented the economic illiteracy of local television reporters.

I’ll be back on Monday with more.

Mamas, Don’t Let Your Babies Grow Up to Be Journalism Majors

Alright, this is hilarious. Or pathetic. Or hilarious in a pathetic sort of way. Or something.

Last week in Boston, a water main broke, rendering tap water undrinkable (unless it was boiled). This inspired the journalism majors at Boston station WHDH to produce some highly emotional footage about two tragic side effects—side effects which, as far as it was possible to tell based on everything they teach in journalism school, were entirely unrelated.

First, we had the report on price gouging, featuring a woman weeping—-weeping!—-because her son had been charged $1 a bottle instead of the recent sale price of $3.99 for a case of 24. Then, we had the entirely separate report on frustrated consumers who had visited five stores and/or waited in long lines to buy bottled water. Apparently nobody at WHDH thought to ask how much longer those lines might have been if prices hadn’t risen.

Nor, apparently, have the folks at WHDH ever learned that the whole point of prices is that they adjust quickly to changes in market conditions, and that that’s a good thing. Even the convenience store owner who is a pure altruist and refuses to profit from a crisis would be well advised to raise the price of water and donate the proceeds to charity, rather than allowing all of the available water to be snatched up by whoever happens to arrive first or elbow everyone else out of the way.

To My RSS Readers

This morning’s post contains some imbedded video from Fox News that looks fine on the blog but shows up as a pointer to the wrong video in the RSS feed. Here is a link to the correct video.

Fair and Balanced

Having linked recently to a Fox News segment hosted by a close evolutionary cousin of a sea cucumber, I am delighted to balance the scales with this clip of a thoughtful and literate three-way conversation about Arizona’s anti-immigration statute, featuring Judge Andrew Napolitano, the journalist Jack Hunter, and my hero, George Mason University’s inestimable Don Boudreaux.

The Jobless Recovery

Mark Skousen, the editor of Forecasts and Strategies, and the proprietor of FreedomFest (where I’ll be speaking on multiple topics this July) sent me the above graph, highlighting just how very jobless this recovery has been, even compared to what we saw after the severe recession of 1981. (There’s been nothing nearly as bad in the intervening three decades.)

What accounts for the difference? The glib answer is “Obama versus Reagan”, but there are plenty of alternative stories. I find some of those stories more convincing than others, but the one thing I’m sure of is that I haven’t put in the kind of hard thought or careful study that entitles me to a strong opinion. I’d be interested, though, in hearing what you guys think.

A Musical Interlude

guitarWhat is the most beautiful folk song you’ve ever heard?

Herewith I offer a list of 25 of my top candidates, with links to brief audio clips. For this purpose, I am defining a “folk song” to be something that would likely be filed in the “folk” section of a Barnes and Noble music department.

Note that the criterion is “most beautiful”, not “favorite”, though of course there’s quite a large overlap between the two.

I am aware that my choices might be colored by the circumstances in which I first heard these songs as well as by their intrinsic merit. I also acknowledge, without a shred of embarrassment, that some might consider the overall tenor of this list to be shockingly lowbrow. Nevertheless, I believe every song on this list to be stunningly beautiful in its way.

Do tell me what I’ve overlooked.

What Women Want: It’s Not Just Wallet Size

If you’re planning to lie about your weight on an online dating site, you’d be well advised to shade downward if you’re a woman and (more surprisingly) upward if you’re a man.

That’s one apparent lesson of the data in this recently published paper by three careful researchers. If I’m reading their tables correctly, they say roughly this:

Taking as given your reported age, height, race, weight, income, attractiveness, education, marital status and so forth, there is some class of users who have about a 50/50 chance of contacting you. Now if you are a 5’4″ woman and you subtract 11 pounds from your reported weight (lowering your body mass index, or BMI, by about 1), then you’ll hear not from 50% of that class but from almost 60%. On the other hand, if you are a 5’10” man and you *add* 7 pounds to your weight (adding about 1 to your BMI), you’ll hear from about 53%.

Moreover, these effects fall off very slowly, so that even very thin women gain from underreporting their weights, and even very heavy men gain from overreporting. The effects also fall off very slowly with BMI differences, so that even quite heavy men prefer thinner women, and even quite thin women prefer heavier men.

Weekend Roundup

roundupHaving taken Monday off for the briefest of honeymoons, I returned on Tuesday with an apparently too-cryptic post that required an addendum to make its meaning clear. Thanks to everyone who sent good wishes and congratulations. I am feeling extremely fortunate.

When I announced last week that I’d be taking a couple of days off, readers took the occasion to raise some issues in the foundations of mathematics. This inspired me to write a long-intended post correcting some elementary errors that frequently come up in these discussions. At least one very confused and feisty commenter jumped to the conclusion that I was saying something controversial and that is was his duty to disagree, loudly and repeatedly.

Thursday’s post was about the magic of the past and the technology of the present, which seem roughly equivalent. And on Friday we took on Arizona’s new immigration law and one of its more fatuous defenders.

With no life-changing events scheduled for the coming weekend, I expect to be back, as usual, on Monday.

Missing the Big Picture

Writing in the New York Times, law professor Kris Kobach promises to rebut all the major objections to Arizona’s new anti-immigration law and proceeds to ignore all the major objections. Professor Kobach’s idea of a major objection is “It’s unfair to demand that aliens carry their documents with them”, whereas my idea of a major objection is “It’s idiotic, hateful and destructive to put obstacles in the way of productive activity.”

The number of “unauthorized aliens” in Arizona at any given moment is estimated as just under a half million—about the same as the number of Jews in New Jersey. Over half the text of the Arizona law is devoted to penalizing employers who hire these people. Now suppose for a moment that the New Jersey legislature were to pass a bill penalizing anyone who hires a Jew. Would Professor Kobach defend this law, as he does Arizona’s, by pointing out that it doesn’t require anyone to carry a driver’s license?

The anti-immigration hysterics keep warning us that foreigners want to come over here and exploit our welfare system. The insincerity of that stance is exposed whenever, as in Arizona, its proponents set out to prevent those very same foreigners from coming here and working.

The Book With All the Answers

bunnyDo you remember Mister Bunny Rabbit?. He was a friend of Captain Kangaroo. One day long ago, when I still measured my age in single digits, Mister Bunny Rabbit announced that he owned a book containing the answer to every possible question. I was skeptical about that book, and so was the Captain, who scoffed mightily at the notion. By way of a test, he looked up the question “Where is Mister Green Jeans right now?”. The book’s answer was “In the attic”, which the Captain knew (I forget how) could not possibly be right. While the Captain was still gloating, Mister Green Jeans ambled in and mentioned that he’d just come from the attic.

The Captain was amazed, and so was I. Long into adulthood, I pondered how that book could possibly have known where Mister Green Jeans was. The best answer I ever got was from the journalist Chris Suellentrop, who speculated that it was probably one of those quantum mechanical things where the act of asking the question caused both the book and Mister Green Jeans to settle down from a cloud of possibilities into mutually compatible states. Others—not so very long ago—speculated that perhaps the book was controlled by a satellite operating a surveillance camera.

Nowadays, of course, we can all carry that book in our pockets. I wonder if today’s children would find anything particularly magical about a reference work that has the answers to pretty much everything, and updates them on the fly.

Just the Facts

jackwebbDuring our brief intermission last week, commenters chose to revisit the question of whether arithmetic is invented or discovered—a topic we’d discussed here and here. This reminded me that I’ve been meaning to highlight an elementary error that comes up a lot in this kind of discussion.

It is frequently asserted that the facts of arithmetic are either “tautologous” or “true by definition” or “logical consequences of the axioms”. Those are three different assertions, and all of them are false. (This is not a controversial statement.)

The arguments made to support these assertions are not subtly flawed; they are overtly ludicrous. Almost always, they consist of “proof by example”, as in “1+1=2 is true by definition; therefore all the facts of arithmetic are true by definition”. Of course one expects to stumble across this sort of “reasoning” on the Internet, but it’s always jarring to see it coming from people who profess an interest in mathematical logic. (I will refrain from naming the worst offenders.)

So let’s consider a few facts of arithmetic:

As Much As Direction

Let us please learn new words that mean as much as direction: wife.

That single cryptic line is the complete text of a poem by Richard Brautigan that I first read almost forty years ago. I still don’t quite get it, but for some reason it’s always struck me as hauntingly beautiful. And, following a momentous weekend, it feels like the right thing to post today.

Edited to add: Apparently this post was as cryptic as the poem. One commenter writes:

You make it sound like you would like to get married but have not taken all necessary steps.

In fact, I took all the necessary steps this weekend. It was a lovely wedding.

Intermission

After six months of blogging nearly every weekday, I’m taking a four day weekend. This will give you a chance to browse through the archives for all the good stuff you might have missed. Or, if you’re looking for a good read to tide you over, I can recommend Chapter Two of my book Fair Play. Some of the examples are dated (Wal-Mart, as far as I know, no longer advertises that “we buy American so you can too”), but it makes a good companion piece to yesterday’s post.

I’ll be back on Tuesday with, I expect, something new to say.

Why I’d Rather Be Blogging

You guys—with your thoughtful, witty and relevant comments—have made me thankful I took up blogging. My (considerable) experience with the mainstream media suggests that you meet a much lower class of people there. Let me give you an example.

Once upon a time I wrote a Forbes column drawing an analogy between protectionism (which discriminates on the basis of national origin) and racism (which discriminates, of course, on the basis of race). (Of course the analogy isn’t perfect. For example, racism can be a solitary hobby, whereas protectionism by its nature forces other people to discriminate as well.) There were many responses, of which my favorite was Pat Buchanan’s screed containing both some hilariously misguided economics and a paragraph I’ve had posted on my office door ever since:

Now I do not know what parents pay to send their kids to the University of Rochester. But if the philosophical imbecility of Landsburg is representative of the faculty, it is too much.

Shortly afterward, I was scheduled to appear on John Gibson’s program on Fox News, where the following exchange took place:

This, in turn, led to a flurry of email. To give you the full flavor, and so as not to bias the sample, I am appending every single email I received on this subject, excepting only one relatively positive note from my mother.

Partly Unclear

In the course of planning a rather significant event for the coming weekend, I was forced, for the first time in my life, to confront the following conundrum:

  • Which is sunnier — “partly sunny” or “partly cloudy”?

My faith in the power of pure reason was severely shaken when I realized I could construct equally plausible arguments in either direction. So, with reluctance, I abandoned theory and turned to evidence, in the form of the logos employed by two of the more popular weather forecasting sites:

 
Weather Underground
Accuweather
Partly Sunny
Partly Cloudy

Weather Underground takes an unambiguous stand: partly cloudy is definitely sunnier than partly sunny. Accuweather is a little, umm, hazier on the issue; apparently at Accuweather, partly cloudy means something like “somewhat wispier clouds, covering more of the central portion of the sun but a bit less of the edges, than partly sunny”. Overall, though, it appears that at Accuweather, partly sunny is sunnier than partly cloudy.

The English Patient

whiteheadA friend living in England (the philosopher Jamie Whyte, actually, whose writing has graced this very blog) sends along a little vignette for the benefit of my American readers who see European health care systems through rose colored glasses.

A 64 year old breast cancer survivor suffering severe back pain is told she’ll have to wait five months for an appointment with an orthopedic surgeon through the National Health Service (NHS). She therefore (and perfectly legally) chooses to pay 250 pounds (about 385 dollars) for a private appointment. He puts her on a waiting list for surgery to remove a cyst from her spine, surgery which is routinely covered by the NHS. But the NHS decides that since she can afford 250 pounds for a private appointment, she can also afford 10,000 pounds (over 15,000 dollars) for private surgery. They therefore deny to provide her the surgery for which she’s been paying taxes her whole life.

This was not an isolated incident; until recently, cancer patients were routinely denied further NHS treatement after privately purchasing lifesaving drugs that are not available through the NHS.

More details here. It’s worth reading the comments, where readers excoriate the patient for “queue jumping” because she used the price system to signal her high demand for medical services. Note that nobody complains about “queue jumping” in the market for, say, oranges, because oranges are not rationed by government bureaucrats and therefore do not generate queues.

The lesson, I think, is that once an inefficient bureaucracy becomes entrenched, a certain fraction of the electorate becomes incapable of imagining anything better. In this case, that fraction seems to have forgotten first that some people need medical care more desperately than others, so that “queue jumping” can be desirable, second that private payments to doctors actually call forth more medical care and therefore shorten queues, and third that maybe it would be better to have a system that didn’t require queuing in the first place.

Overselling

deanmartinOver at Overcoming Bias, Robin Hanson blogs about a science fiction novel that posits a world where people routinely sell shares in their future income. (I have not read the novel, which is called The Unincorporated Man.) Robin laments that while many reviewers have taken it for granted that we wouldn’t want to allow such contracts, none seem to have seriously engaged the idea.

I’m not sure if this counts as serious engagement, but I am reminded of the apparently little-known fact that the singer/actor/TV phenomenon Dean Martin did exactly this. In fact, he overdid exactly this. By the time he was 27 years old, Martin had sold 10% of himself to MCA Records, 20% to his manager DIck Richards, 35% to his other manager Lou Perry, and 25% to the mobster Frank Costello. That left him with 5% of himself—“$50 for every grand he made” in the words of writer Nick Tosches. A year later, he hired yet another manager and sold him another 10%. Having now sold 105% of himself, it became imprudent to earn money. Therefore, in need of something to live on, Martin sold yet another 10% of himself to nighclub owner Angel Lopez.

Weekend Roundup

The bulk of the week was devoted to Krugman on green economics, with posts here, here, and here.

Although I agreed with Krugman on some points and disagreed on others, there were two places where I not only disagreed but thought he had the economics wrong. First, he is wrong when he suggests that if we’re more risk averse, it follows that we should spend more on climate control. The reason is that risk averse people don’t like income inequality (because it boosts the risk of being born poor), and spending more on climate control exacerbates income inequality across generations. Therefore risk aversion cuts both ways on this issue. Second, Krugman is wrong when he gives (some) credence to James Hansen’s economically illiterate belief that altruism is somehow less effective under a cap-and-trade regime than under an emissions tax.

To round out the week, we had two posts about shameless hucksters trying to gull the public. Those posts are here and here.

As always, I’ll be back on Monday.

Tax Relief, Obama Style

What a relief. Now that April 15 is out of the way, my tax rate is back to zero for another year.

At least that’s the way the President of the United States seems to have it figured—your tax burden, according to him, is measured by what you’re paying right this moment as opposed to what you’re obligated to pay in the future.

taxburdenThat’s the only possible interpretation of his statement last night that Tea Partiers (and others) should be thanking him for cutting taxes. The reality is that President Obama, like President Bush before him, has rather dramatically raised government spending and therefore has raised your taxes. To say otherwise is like saying you got your new swimming pool for free because you put it on your credit card.

Once the money is spent, the bill must eventually come due—and there’s nobody around to foot that bill except the taxpayers. We are locked into higher current spending and therefore locked into higher future taxes. The president hasn’t lowered taxes; he’s raised and then deferred them. To say otherwise is—let’s be blunt—a flat-out lie.

More Triumphs of Capitalism

Do me a favor. Listen to this 30 second audio clip and let me know if you feel like you can speak a little Gaelic.

gaelic

The clip is from the Subliminal Learn Gaelic Irish/Scottish CD available from Brainwave Mind Voyages. According to their website, listening to this CD while you sleep will train you not just to speak Gaelic but to read it as well. (If the clip above didn’t work for you, please try it again while sleeping.) If you really want to go high-tech, they also offer an ultrasonic track that teaches you Gaelic in complete silence.

In case Gaelic is not your thing, the same company offers subliminal CDs that will teach you to dance, trade stocks, or stop pulling your eyelashes. Or on the racier side, there are CDs for subliminal breast enhancement, “natural male enhancement”, and combating both impotence and the gag reflex.

Unfortunately, nobody seems to have developed a technology that will teach you to keep squirrels in your pocket while you sleep. For the time being, only the traditional methods are available. But who knows what the future might bring?

Krugman on Climate

Yesterday I blogged about Paul Krugman’s recent piece on climate control policy. The bottom line: After recovering from a shaky start, Krugman does a good job of laying out the issues and posing many (though not quite all) of the right questions. But I’m not sure he gets the answers right.

A few years ago, writing in Slate, I listed the key questions that the Al Gores of the world mostly fail to address or even acknowledge. (See also the discussion on pages 186-190 of The Big Questions.) Krugman (thankfully) is no Al Gore, and he does address most of these questions. Let’s see how he does with them.

We had lots of new readers this week after several posts got considerable attention around the blogosphere: One on the difference between what the economist says and what the non-economist hears, one on blogging and the future of math (with its companion piece on four-dimensional tic-tac-toe), and two posts from the preceding week: My most influential books list and a post on what’s wrong with happiness research.

Bookending the week were my discovery of myself as a character in a novel and an extraordinary triumph of capitalism.

I look forward to seeing our new and old readers again on Monday.

Blogging, Tic Tac Toe and the Future of Math

Blogging, as you might have heard, is changing the face of the media. It may also be changing the face of mathematical research. For the first time ever, a substantial mathematical problem has been solved via an accumulation of blog comments, all building on each other. Could this be the future of mathematical research?

Before I explain the problem, let’s talk a little about tic-tac-toe. As you probably figured out long ago, intelligent players of ordinary tic-tac-toe (on a 3 by 3 board) will invariably battle to a draw. But, as you probably also figured out, not every game ends in a draw, because not every player is intelligent.

On the other hand, if we blacken out the three squares on the main diagonal and don’t allow anyone to play there (so the game ends when the remaining six squares are filled, then every game is sure to end in a draw. There’s simply no way to get three in a row when you’re not allowed to play on the diagonal:

Tic Tac Toe in Four Dimensions

In high school, we used to play four-dimensional tic-tac-toe. The board looks like this:

Here each four-by-four subsquare is an ordinary tic-tac-toe board (except that it’s four-by-four instead of the traditional three-by-three). You should think of the four subsquares in the first column (or any other column) as stacked above each other in the third dimension. The red x’s form a vertical line in that direction, so if you manage to place four x’s in those positions, you’re a winner.

You should also think of the four subsquares in the first row as stacked above each other in yet another dimension. The red o’s form a diagonal line passing from the bottom left to the top right (using “bottom” and “top” to refer to directions in this fourth dimension). And the black x’s form another kind of diagonal line, passing from one corner to another through all four dimensions. So there are a lot of ways to win this game.

Hearing Problems

hearingFirst, kudos to both Bennett Haselton and Xan, each of whom nailed yesterday’s puzzle in comments. Bennett’s answer has the advantage of requiring no knowledge of algebra; Xan’s has the advantage of giving a (much) more precise bound on how long it takes for history to repeat itself.

Now on to something completely different:

During a belated conversation about health care policy, a colleague remarked that “of course, nobody would want to live in a world where rich people and poor people got the same kind of health care”. The economists around the table all nodded in agreement and moved on to matters that were actually controversial.

It occurs to me that had there been a few non-economists at the table, someone might have objected to my colleague’s matter-of-fact (and surely accurate) observation. And it occurs to me also that maybe there’s a general lesson here about how economists communicate—or fail to communicate—with the world at large.

The Yukiad, Perpetual Motion and Me

yukiadIt’s a bit of an odd feeling to be reading a novel and stumble upon yourself as a character. Well, at least a well-disguised version of yourself. The novel is Victor Snaith’s The Yukiad, and the character is a large Scotsman named Pans who tugs at his earrings when he becomes agitated. I am neither Scottish, nor earringed, nor particularly large, but I suspect that Pans, viewed through the haze of poetic license, is I.

When we meet Pans, he is hovering over a glass contraption—a perpetual motion machine, really—consisting of a circular tube containing several colored beads, which travel around the tube, some clockwise, some counterclockwise, all at the same speed, bouncing off each other in perfectly elastic collisions whenever they collide. Pans is currently tugging at his earrings so hard as to cause some concern for the integrity of his earlobes, as he ponders the following question:

But wull tha’ aver gut bark to weer tha’s started, at a’, at a’?

Well, okay, maybe I’m not Pans. Maybe I’m the character Sherloch Humes, a “trim but rather wrinkled gentleman in worsteds”, who calculates for Pans’s benefit that “the configuration of beads is guaranteed to have exactly replicated itself by the year two thousand and nineteen”. I believe that I am the inspiration for one of these characters and that the mathematician Leonid Vaserstein (who is neither Scottish nor wrinkled) is the inspiration for the other, and here is why:
