Might this help explain Russia and Ukraine?

by Tyler Cowen

The excellent Akos Lada, a graduate student at Harvard, has a new paper on why countries sometimes invade their neighbors, it is called “The Dark Side of Attraction,” the abstract is here:

I argue that the diffusion of domestic political institutions is a source of wars. In the presence of an inspiring foreign regime, repressive elites fear that their citizens emulate the foreign example and revolt. As a result, a dictator starts a war against an attractive foreign regime, seeking to destroy this alternative model. Such wars are particularly likely when there are strong religious, ethnic or cultural ties between the dictator’s opposition and the inspiring country – connections that allow citizens to draw easy comparisons. My posited mechanism explains three case studies. The first describes the Russian invasion of Hungary in 1849. The second case study analyzes the origins of the First World War (1914-8), where Austria-Hungary invaded Serbia. The final case study discusses the Iran-Iraq War (1980-8). In all three cases, a dictator started a war in order to extinguish the foreign flame that fueled his domestic opposition.

Akos occasionally writes blog posts here.  Here is our previous coverage of Akos Lada — he stands a good chance of being one of the significant new “big picture” thinkers in economics.

African immigrant fact of the day

by Tyler Cowen

That’s African immigrants to the United States, here is the fact:

In 2009, 41.7 percent of African-born adults age 25 and older had a bachelor’s degree or higher, compared to 28.1 percent of native-born adults and 26.8 percent of all foreign-born adults.

The source is here, further information about African immigrants is here.  They speak good English at very high rates — close to three-quarters — and they are more likely than other immigrants to be participating in the labor force.  And their importance is rising:

Though African immigrants represented only 0.4 percent of all foreign born in 1960, this share grew to 1.4 percent in 1980, to 1.8 percent in 1990, and to 2.8 percent in 2000…

There is also this:

People born in the U.S. were roughly four times as likely to report engaging in violent behavior than immigrants from Asia and Africa…

The future of immigration to America is likely African, some south Asian, and Chinese, with Latinos continuing to have a presence as well.

A Problem With Increased Surveillance

by jeff

Any punishment designed for deterrence is based on the following calculation.  The potential criminal weighs the benefit of the crime against the cost, where the cost is equal to the probability of being caught multiplied by the punishment if caught.

Taking surveillance technology as given, the punishment is set in order to calibrate the right-hand-side of that comparison.  Optimally, the expected punishment equals the marginal social cost of the crime so that crimes whose marginal social cost outweighs the marginal benefit are deterred.

When technology allows improved surveillance, the law does not adjust automatically to keep the right-hand side constant.  Indeed there is a ratchet effect in criminal law:  penalties never go down.

So we naturally hate increased surveillance, even those of us who would welcome it in a first-best world where punishments adjust along with technology.

The Great Autocrat Moderation, and when will it end?

by Tyler Cowen

We’ve now seen a good twenty-five years of autocrats backing down, ceding power, and refusing to escalate, starting  around 1989 if not earlier.  Arguably North Korea and Saddam Hussein have been partial exceptions, but even there North Korea has stayed in its shell and Saddam had in fact largely disarmed his WMD.  We also see many autocrats — most notably those of China — who pursue remarkably sophisticated courses of action.  Just think how much more deftly they handled Occupy Hong Kong than the Ferguson police dealt with their situation.  Even the Iranian leaders seem quite sophisticated, even though most of us do not share their goals or endorse their means.

I call it The Great Autocrat Moderation.

If we look back in history, are autocrats generally this rational and conciliatory?  I am struck reading the new Andrew Roberts biography of Napoleon how he grew drunk with success and overreached and of course eventually failed (twice).  Mussolini, Hitler, Stalin, and Mao are some additional obvious examples of autocrats who, in terms of procedural rationality, simply collapsed at some point and very dramatically overreached.

Of course these are tricky examples.  The most famous autocrats are arguably going to be more subject to overreach, which in part drives their fame (infamy), and so if we consult our historical memories we may be selecting for overreach.  Your typical earlier autocrat may have been more rational than this list of ambitious tyrants might imply.  Was the typical dictator of Paraguay, historically speaking, really so irrational?  Still, it does seem that autocrats have been relatively benign as of late.

So how about Putin?  Is he like the autocrats of the last twenty-five years, or he is more like Napoleon and Mussolini with regard to his long-term procedural rationality?

I do not myself expect The Great Autocrat Moderation to continue for much longer. Let us not forget that some autocratic “tournaments” select for overreach, namely the autocrat had to think he could, against long odds, rise to the top and stay there.

I am indebted to a conversation with John Nye about the topics of this blog post.

Why Jonathan Gruber is Paid the Big Bucks

by Arnold Kling

Tyler Cowen comes to his defense.

I’ve disagreed with Gruber from the beginning on health care policy and I thought his ObamaCare comic book did the economics profession — and himself — a disservice. But I’m simply not very interested in his proclamations on tape, which as far as I can tell are mostly correct albeit overly cynical.

My remarks:

1, Gruber is not paid the big bucks to be a political tactician. In particular, whether or not Obamacare was sold deceptively was not his call to make.

2. For me, the problem with democracy is not the intelligence, or alleged lack thereof, among voters. I just think that the wisdom of crowds is channeled more effectively through exit than through voice. As for democracy, it is a good way of arranging for the routine replacement of high-level officials. It is otherwise much over-rated.

3. Gruber is paid the big bucks because he has a quantitative model of how insurance health reforms will play out. Relative to most academic economists and policy makers, my level of trust in such models is rather low. For me, it would be a better world if Gruber and his model were not held in such high regard. But I would have made this point, and probably did so, before the recent controversy.

4. If you need proof of Gruber’s contempt for your intelligence, all you need to do is skim the comic book to which Tyler refers. The comic book left me with the impression that Gruber lives in a Krugmanesque bubble, in which any disagreement must be dismissed as stemming from extreme ignorance and/or evil intent.

5. I think that the extent to which the attacks on Gruber have become personal is something that every economist, regardless of ideology, will come to regret. I am all for criticizing the ideas and the world view that underlie Obamacare. However, a world in which every economist who steps into the policy arena is subjected to opposition research and “gotcha” attacks is not going to be pretty.

All In All, Another Brick In The Motte

by Scott Alexander

One of the better things I’ve done with this blog was help popularize Nicholas Shackel’s “motte and bailey doctrine”. But I’ve recently been reminded I didn’t do a very good job of it. The original discussion is in the middle of a post so controversial that it probably can’t be linked in polite company – somewhat dampening its ability to popularize anything.

In order to rectify the error, here is a nice clean post on the concept that adds a couple of further thoughts to the original formulation.

The original Shackel paper is intended as a critique of post-modernism. Post-modernists sometimes say things like “reality is socially constructed”, and there’s an uncontroversially correct meaning there. We don’t experience the world directly, but through the categories and prejudices implicit to our society; for example, I might view a certain shade of bluish-green as blue, and someone raised in a different culture might view it as green. Okay.

Then post-modernists go on to say that if someone in a different culture thinks that the sun is light glinting off the horns of the Sky Ox, that’s just as real as our own culture’s theory that the sun is a mass of incandescent gas a great big nuclear furnace. If you challenge them, they’ll say that you’re denying reality is socially constructed, which means you’re clearly very naive and think you have perfect objectivity and the senses perceive reality directly.

The writers of the paper compare this to a form of medieval castle, where there would be a field of desirable and economically productive land called a bailey, and a big ugly tower in the middle called the motte. If you were a medieval lord, you would do most of your economic activity in the bailey and get rich. If an enemy approached, you would retreat to the motte and rain down arrows on the enemy until they gave up and went away. Then you would go back to the bailey, which is the place you wanted to be all along.

So the motte-and-bailey doctrine is when you make a bold, controversial statement. Then when somebody challenges you, you claim you were just making an obvious, uncontroversial statement, so you are clearly right and they are silly for challenging you. Then when the argument is over you go back to making the bold, controversial statement.

Some classic examples:

1. The religious group that acts for all the world like God is a supernatural creator who builds universes, creates people out of other people’s ribs, parts seas, and heals the sick when asked very nicely (bailey). Then when atheists come around and say maybe there’s no God, the religious group objects “But God is just another name for the beauty and order in the Universe! You’re not denying that there’s beauty and order in the Universe, are you?” (motte). Then when the atheists go away they get back to making people out of other people’s ribs and stuff.

2. Or…”If you don’t accept Jesus, you will burn in Hell forever.” (bailey) But isn’t that horrible and inhuman? “Well, Hell is just another word for being without God, and if you choose to be without God, God will be nice and let you make that choice.” (motte) Oh, well that doesn’t sound so bad, I’m going to keep rejecting Jesus. “But if you reject Jesus, you will BURN in HELL FOREVER and your body will be GNAWED BY WORMS.” But didn’t you just… “Metaphorical worms of godlessness!”

3. The feminists who constantly argue about whether you can be a real feminist or not without believing in X, Y and Z and wanting to empower women in some very specific way, and who demand everybody support controversial policies like affirmative action or affirmative consent laws (bailey). Then when someone says they don’t really like feminism very much, they object “But feminism is just the belief that women are people!” (motte) Then once the person hastily retreats and promises he definitely didn’t mean women aren’t people, the feminists get back to demanding everyone support affirmative action because feminism, or arguing about whether you can be a feminist and wear lipstick.

4. Proponents of pseudoscience sometimes argue that their particular form of quackery will cure cancer or take away your pains or heal your crippling injuries (bailey). When confronted with evidence that it doesn’t work, they might argue that people need hope, and even a placebo solution will often relieve stress and help people feel cared for (motte). In fact, some have argued that quackery may be better than real medicine for certain untreatable diseases, because neither real nor fake medicine will help, but fake medicine tends to be more calming and has fewer side effects. But then once you leave the quacks in peace, they will go back to telling less knowledgeable patients that their treatments will cure cancer.

5. Critics of the rationalist community note that it pushes controversial complicated things like Bayesian statistics and utilitarianism (bailey) under the name “rationality”, but when asked to justify itself defines rationality as “whatever helps you achieve your goals”, which is so vague as to be universally unobjectionable (motte). Then once you have admitted that more rationality is always a good thing, they suggest you’ve admitted everyone needs to learn more Bayesian statistics.

6. Likewise, singularitarians who predict with certainty that there will be a singularity, because “singularity” just means “a time when technology is so different that it is impossible to imagine” – and really, who would deny that technology will probably get really weird (motte)? But then every other time they use “singularity”, they use it to refer to a very specific scenario of intelligence explosion, which is far less certain and needs a lot more evidence before you can predict it (bailey).

The motte and bailey doctrine sounds kind of stupid and hard-to-fall-for when you put it like that, but all fallacies sound that way when you’re thinking about them. More important, it draws its strength from people’s usual failure to debate specific propositions rather than vague clouds of ideas. If I’m debating “does quackery cure cancer?”, it might be easy to view that as a general case of the problem of “is quackery okay?” or “should quackery be illegal?”, and from there it’s easy to bring up the motte objection.

Recently, a friend (I think it was Robby Bensinger) pointed out something I’d totally missed. The motte-and-bailey doctrine is a perfect mirror image of my other favorite fallacy, the weak man fallacy.

Weak-manning is a lot like straw-manning, except that instead of debating a fake, implausibly stupid opponent, you’re debating a real, unrepresentatively stupid opponent. For example, “Religious people say that you should kill all gays. But this is evil. Therefore, religion is wrong and barbaric. Therefore we should all be atheists.” There are certainly religious people who think that you should kill all gays, but they’re a small fraction of all religious people and probably not the ones an unbiased observer would hold up as the best that religion has to offer.

If you’re debating the Pope or something, then when you weak-man, you’re unfairly replacing a strong position (the Pope’s) with a weak position (that of the guy who wants to kill gays) to make it more attackable.

But in motte and bailey, you’re unfairly replacing a weak position (there is a supernatural creator who can make people out of ribs) with a strong position (there is order and beauty in the universe) in order to make it more defensible.

So weak-manning is replacing a strong position with a weak position to better attack it; motte-and-bailey is replacing a weak position with a strong position to better defend it.

This means people who know both terms are at constant risk of arguments of the form “You’re weak-manning me!” “No, you’re motte-and-baileying me!“.

Suppose we’re debating feminism, and I defend it by saying it really is important that women are people, and you attack it by saying that it’s not true that all men are terrible. Then I can accuse you of making life easy for yourself by attacking the weakest statement anyone vaguely associated with feminism has ever pushed. And you can accuse me if making life too easy for myself by defending the most uncontroversially obvious statement I can get away with.

So what is the real feminism we should be debating? Why would you even ask that question? What is this, some kind of dumb high school debate club? Who the heck thinks it would be a good idea to say “Here’s a vague poorly-defined concept that mind-kills everyone who touches it – quick, should you associate it with positive affect or negative affect?!”

Taboo your words, then replace the symbol with the substance. If you have an actual thing you’re trying to debate, then it should be obvious when somebody’s changing the topic. If working out who’s using motte-and-bailey (or weak man) is remotely difficult, it means your discussion went wrong several steps earlier and you probably have no idea what you’re even arguing about.

PS: Nicholas Shackel, original inventor of the term, weighs in.

Galileo still right about gravity

by Jason Kottke

If you believe in gravity, then you know that if you remove air resistance, a bowling ball and a feather will fall at the same rate. But seeing it actually happen, in the world's largest vacuum chamber (122 feet high, 100 feet in diameter), is still a bit shocking.

In the late 1500s, Galileo was the first to show that the acceleration due to the Earth's gravity was independent of mass with his experiment at the Leaning Tower of Pisa, but that pesky air resistance caused some problems. At the end of the Apollo 15 mission, astronaut David Scott dropped a hammer and a feather in the vacuum on the surface of the Moon:

Political Order and Political Decay

by Arnold Kling

That is the title of Francis Fukuyama’s latest book. I have started reading it. So far, I would summarize it as saying that government must overcome both market failure and government failure. That is, it needs to be effective at providing public goods while serving everyone equally (not succumbing to the problems of public choice). I might summarize this as follows:

Public Goods Provided Public Goods Not Provided
Treats People Equally good government weak government
Privileges Elites crony government predatory government

Think of Denmark as good government, China as crony government, Zaire under Mobutu as predatory government, and Afghanistan as weak government. I assume that “political decay” will mean the movement from good government toward either weak government or crony government.

For a review by someone who has finished the book, see Michael Barone.

Awesome photos show how Google is using a camel to map deserts

by Sarah Kliff

When Google wants to create its Street View maps — the ones that show the buildings and sidewalks that line the world's streets — it sends a funny-looking car with a camera on top off to capture the footage.

Those StreetView cars work great in places where there are roads. But in the world's more remote locations — a desert in Abu Dhabi, lets say — vehicles don't cut it. Enter Raffia, the camel carrying a camera across the Liwa oasis to produce more Google Maps.

(Google/YouTube)

Of course, the camel carrying a camera is not an everyday sight. But whats more striking about the video is the sheer size of the Liwa Oasis, an expansive stretch of desert that runs along the Persian Gulf.

This is a somewhat surreal video of Raffia, with her guide, in action.

You can see the results of Raffia's work on the Google Treks site, replete with many more camels who were not carrying cameras.

Online Education for Pre-School

by Alex Tabarrok

Online education continues to expand rapidly:

WASHINGTON—Saying the option is revolutionizing the way the nation’s 3- and 4-year-olds prepare for the grade school years ahead, a Department of Education report released Thursday confirmed that an increasing number of U.S. toddlers are now attending online preschool. “We found that a growing number of American toddlers are eschewing the traditional brick-and-mortar preschools in favor of sitting down in front of a computer screen for four hours a day and furthering their early psychosocial development in a virtual environment,” said the report’s author, Dr. Stephen Forrest, who said that the affordability and flexibility characteristic of online pre-primary education are what make the option most appealing, allowing young children to learn their shapes and colors on a schedule that works best for them. “With access to their Show-And-Tell message boards, recess timers, and live webcams of class turtle tanks, most toddlers are finding that they can receive the same experience of traditional preschooling from the comfort of their parents’ living room or home office. In addition, most cited the ability to listen to their teacher’s recordings of story time at their own pace as a significant benefit of choosing an online nursery school.” Forrest added that, despite their increasing popularity, many parents remain unconvinced that online preschools provide the same academic benefits as actually hearing an instructor name farm animals and imitate their noises in person.

The United States of Alcoholism

by Jason Kottke

Drinking Rate USA

30% of Americans don't drink any alcohol during a typical week. On the other end of the scale, ten percent of Americans consume more than 10 drinks every single day. More from Wonkblog.

I double-checked these figures with Cook, just to make sure I wasn't reading them wrong. "I agree that it's hard to imagine consuming 10 drinks a day," he told me. But, "there are a remarkable number of people who drink a couple of six packs a day, or a pint of whiskey."

As Cook notes in his book, the top 10 percent of drinkers account for well over half of the alcohol consumed in any given year. On the other hand, people in the bottom three deciles don't drink at all, and even the median consumption among those who do drink is just three beverages per week.

This is shocking to me. I wonder what the distribution is within the top 10%...there must be people in the top 1% who drink, what, 30 drinks per day? Is that even possible day after day without very serious consequences? (via mr)

Update: Over at Forbes, Trevor Butterworth casts doubt on the conclusions in the Wonkblog article.

The source for this figure is "Paying the Tab," by Phillip J. Cook, which was published in 2007. If we look at the section where he arrives at this calculation, and go to the footnote, we find that he used data from 2001-2002 from NESARC, the National Institute on Alcohol Abuse and Alcoholism, which had a representative sample of 43,093 adults over the age of 18. But following this footnote, we find that Cook corrected these data for under-reporting by multiplying the number of drinks each respondent claimed they had drunk by 1.97 in order to comport with the previous year's sales data for alcohol in the US. Why? It turns out that alcohol sales in the US in 2000 were double what NESARC's respondents -- a nationally representative sample, remember -- claimed to have drunk.

Additionally, the statement I made above -- "ten percent of Americans consume more than 10 drinks every single day" -- is not true, even if the data is correct. Instead, it is accurate to say that top 10% consumes an average of 10 drinks daily...some individuals may drink 4/day and some 18/day. Looks like it's time for a reread of How to Lie with Statistics and A Mathematician Reads the Newspaper. (via @harryh & @gfilpus)

Partyism in America is getting worse

by Tyler Cowen

In 1960, 5 percent of Republicans and 4 percent of Democrats said that they would feel “displeased” if their son or daughter married outside their political party. By 2010, those numbers had reached 49 percent and 33 percent. Republicans have been found to like Democrats less than they like people on welfare or gays and lesbians. Democrats dislike Republicans more than they dislike big business.

And this:

To test for political prejudice, Shanto Iyengar and Sean Westwood, political scientists at Stanford University, conducted a large-scale implicit association test with 2,000 adults. They found people’s political bias to be much larger than their racial bias. When Democrats see “joy,” it’s much easier for them to click on a corner that says “Democratic” and “good” than on one that says “Republican” and “good.”

To find out whether such attitudes predict behavior, Iyengar and Westwood undertook a follow-up study. They asked more than 1,000 people to look at the resumes of several high-school seniors and say which ones should be awarded a scholarship. Some of these resumes contained racial cues (“president of the African American Student Association”) while others had political ones (“president of the Young Republicans”).

Race mattered. African-American participants preferred the African-American candidates 73 percent to 27 percent. Whites showed a modest preference for African-American candidates, as well, though by a significantly smaller margin. But partisanship made a much bigger difference. Both Democrats and Republicans selected their in-party candidate about 80 percent of the time.

That is from Cass Sunstein.

Hedge fund rats

by Tyler Cowen
Joswald1

Seriously, has no one heard of the EMH?

Why should trading be the province of humans only?:

One project is Michael Marcovici’s Rat Trader. The book describes the training of laboratory rats to trade in foreign exchange and commodity futures markets. Marcovici says the rats “outperformed some of the world’s leading human fund managers.” The rats were trained to press a red or green button to give buy or sell signals, after listening to ticker tape movements represented as sounds. If they called the market right they were fed, if they called it wrong they got a small electric shock. Male and female rats performed equally well. The second generation of rattraders, cross-bred from the best performers in the first generation, appeared to have even better performance, although this is a preliminary result, according to the text. Marcovici’s plan, he writes, is to breed enough of them to set up a hedge fund.

I don’t myself like the electric shock idea, but there you go.  That is from Diane Coyle, and for the pointer I thank Michael Gibson.

The Case for Open Borders

by Alex Tabarrok

Dylan Matthews summarizes the The Case for Open Borders drawing on an excellent interview with Bryan Caplan. Here is one bit from the interview:

Letting someone get a job is not a kind of charity. It’s not a welfare program. It’s just the government leaving people alone to go and make something out of their lives. When most people are on earth are dealt such a bad hand, to try to stop them from bettering their condition seems a very cruel thing to do to someone.

My elevator pitch has no economics in it, because the economics is actually too subtle to really explain in an elevator pitch. If I had a little bit more time, I would say, “What do you think the effects for men have been of more women in the workforce?”

Are there some men who are worse off? Sure. But would we really be a richer society if we kept half the population stuck at home? Isn’t it better to take people who have useful skills and let them do something with it, than to just keep them locked up someplace where their skills go to waste?

Isn’t that not just better for them, but better for people in general, if we allow people to use their skills to contribute to the world instead of keeping them shut up someplace where they just twiddle their thumbs or do subsistence agriculture or whatever?

On the economics, David Roodman has a characteristically careful and comprehensive review written for Givewell of the evidence on the effect of immigration on native wages. He writes, “the available evidence paints a fairly consistent and plausible picture”:

  • There is almost no evidence of anything close to one-to-one crowding out by new immigrant arrivals to the job market in industrial countries. Most studies find that 10% growth in the immigrant “stock” changes natives’ earnings by between –2% and +2% (@Longhi, Nijkamp, and Poot 2005@, Fig 1; @Peri 2014@, Pg 1). Although serious questions can be raised about the reliability of most studies, the scarcity of evidence for great pessimism stands as a fact (emphasis added, AT)….
  • One factor dampening the economic side effects of immigration is that immigrants are consumers as well as producers. They increase domestic demand for goods and services, perhaps even more quickly than they increase domestic production (@Hercowitz and Yashiv 2002@), since they must consume as soon as they arrive. They expand the economic pie even as they compete for a slice. This is not to suggest that the market mechanism is perfect—adjustment to new arrivals is not instantaneous and may be incomplete—but the mechanism does operate.
  • A second dampener is that in industrial economies, the capital supply tends to expand along with the workforce. More workers leads to more offices and more factories. Were receiving economies not flexible in this way, they would not be rich. This mechanism too may not be complete or immediate, but it is substantial in the long run: since the industrial revolution, population has doubled many times in the US and other now-wealthy nations, and the capital stock has kept pace, so that today there is more capital per worker than 200 years ago.
  • A third dampener is that while workers who are similar compete, ones who are different complement. An expansion in the diligent manual labor available to the home renovation business can spur that industry to grow, which will increase its demand for other kinds of workers, from skilled general contractors who can manage complex projects for English-speaking clients to scientists who develop new materials for home building. Symmetrically, an influx of high-skill workers can increase demand for low-skill ones. More computer programmers means more tech businesses, which means more need for janitors and security guards. Again, the effect is certain, though its speed and size are not.
  • …one way to cushion the impact of low-skill migration on low-skill workers already present is to increase skilled immigration in tandem.

Plaudits are due to Givewell. While others are focused on giving cows, Givewell is going after the really big gains.

Another Education Peculiarity

by Arnold Kling

Neerav Kingsland writes,

the wealthy are paying for status (and perhaps peer effects) more so than they are paying for educational programming.

Schools respond when people pay for status: we get beautiful buildings, wonderful extracurriculars, and a lot of social events.

Of course, these things don’t spread to all schools because they involve costly goods rather than innovations in instruction.

So instead of the wealthy subsidizing the early adoption of innovation, the reverse seems more likely true: it’s the practices of urban charter schools (Teach Like A Champion, Leveraged Leadership, blended learning, etc.) that will end up spreading to the suburbs.

Read the whole thing. If elite schools are status goods, then it will be difficult to dislodge them from their perches–until it becomes easy. I have suggested before that you could see a very rapid “tipping” away from elite schools. Once enough parents decide that there are other ways to achieve parenting status than sending kids to erstwhile elite schools, the elite schools collapse.

Classic French cheeses restricted by FDA

by Jason Kottke

Tighter FDA restrictions are keeping some classic French cheeses (Roquefort, Morbier, Tomme de Savoie) out of the US and even some American cheese makers are halting production of their cheeses because they're afraid their products won't meet the new standards.

In early August, these cheeses and many more landed on an FDA Import Alert because the agency found bacterial counts that exceeded its tolerance level. Cheeses on Import Alert can't be sold in the U.S. until the producer documents corrective action and five samples test clean, a process that can take months.

Of course, French creameries haven't changed their recipes for any of these classic cheeses. But their wheels are flunking now because the FDA has drastically cut allowances for a typically harmless bacterium by a factor of 10.

Even Parmigiano-Reggiano might be threatened by the new restrictions. Ridiculous.

Should Only Winners Get Trophies?

by Alex Tabarrok

A Reason-Rupee poll asked

Do you think all kids who play sports should receive a trophy for their participation, or should only the winning players be awarded trophies?

Overall, an estimated 57% Americans said that only the winning players should be awarded trophies but there were big differences according to gender, race, politics, education and income. 62% of men, for example, said that only the winning players should be awarded trophies compared to 52% of women. These results are consistent with experiments in which women tend to shy away from competition (perhaps with long-run consequences in the workforce). Whites opt for trophies to the winners-only at 63% compared to African Americans at just 44% and Hispanics at 39%. A whopping 80% of libertarians say that trophies should go only to the winners compared to conservatives at 63% and liberals and progressives both at 53%. More educated respondents were more likely to opt for trophies for only the winners.  Trophies for the winners also increased strongly in income which could be because people with high income feel that they are winners or perhaps because people with high incomes are the types of people who enjoy competition.

Note that these are raw differences not betas from a statistical regression and since income, race, education etc. aren’t independent we don’t know which are the most controlling although the results point in directions consistent with other evidence. The data can be found here.

Policing by consent

by Jason Kottke

In light of the ongoing policing situation in Ferguson, Missouri in the wake of the shooting of an unarmed man by a police officer and how the response to the community protests is highlighting the militarization of US police departments since 9/11, it's instructive to look at one of the first and most successful attempts at the formation of a professional police force.

The UK Parliament passed the first Metropolitan Police Act in 1829. The act was introduced by Home Secretary Sir Robert Peel, who undertook a study of crime and policing, which resulted in his belief that the keys to building an effective police force were to 1) make it professional (most prior policing had been volunteer in nature); 2) organize as a civilian force, not as a paramilitary force; and 3) make the police accountable to the public. The Metropolitan Police, whose officers were referred to as "bobbies" after Peel, was extremely successful and became the model for the modern urban police force, both in the UK and around the world, including in the United States.

At the heart of the Metropolitan Police's charter were a set of rules either written by Peel or drawn up at some later date by the two founding Commissioners: The Nine Principles of Policing. They are as follows:

1. To prevent crime and disorder, as an alternative to their repression by military force and severity of legal punishment.

2. To recognise always that the power of the police to fulfil their functions and duties is dependent on public approval of their existence, actions and behaviour, and on their ability to secure and maintain public respect.

3. To recognise always that to secure and maintain the respect and approval of the public means also the securing of the willing co-operation of the public in the task of securing observance of laws.

4. To recognise always that the extent to which the co-operation of the public can be secured diminishes proportionately the necessity of the use of physical force and compulsion for achieving police objectives.

5. To seek and preserve public favour, not by pandering to public opinion, but by constantly demonstrating absolutely impartial service to law, in complete independence of policy, and without regard to the justice or injustice of the substance of individual laws, by ready offering of individual service and friendship to all members of the public without regard to their wealth or social standing, by ready exercise of courtesy and friendly good humour, and by ready offering of individual sacrifice in protecting and preserving life.

6. To use physical force only when the exercise of persuasion, advice and warning is found to be insufficient to obtain public co-operation to an extent necessary to secure observance of law or to restore order, and to use only the minimum degree of physical force which is necessary on any particular occasion for achieving a police objective.

7. To maintain at all times a relationship with the public that gives reality to the historic tradition that the police are the public and that the public are the police, the police being only members of the public who are paid to give full-time attention to duties which are incumbent on every citizen in the interests of community welfare and existence.

8. To recognise always the need for strict adherence to police-executive functions, and to refrain from even seeming to usurp the powers of the judiciary of avenging individuals or the State, and of authoritatively judging guilt and punishing the guilty.

9. To recognise always that the test of police efficiency is the absence of crime and disorder, and not the visible evidence of police action in dealing with them.

As police historian Charles Reith noted in 1956, this philosophy was radical when implemented in London in the 1830s and "unique in history and throughout the world because it derived not from fear but almost exclusively from public co-operation with the police, induced by them designedly by behaviour which secures and maintains for them the approval, respect and affection of the public". Apparently, it remains radical in the United States in 2014. (thx, peter)

Humans need not apply

by Jason Kottke

This video combines two thoughts to reach an alarming conclusion: "Technology gets better, cheaper, and faster at a rate biology can't match" + "Economics always wins" = "Automation is inevitable."

That's why it's important to emphasize again this stuff isn't science fiction. The robots are here right now. There is a terrifying amount of working automation in labs and warehouses that is proof of concept.

We have been through economic revolutions before, but the robot revolution is different.

Horses aren't unemployed now because they got lazy as a species, they're unemployable. There's little work a horse can do that pays for its housing and hay.

And many bright, perfectly capable humans will find themselves the new horse: unemployable through no fault of their own.
