How to talk about books you haven't read.

So this Frenchman Bayard wrote a book, about how to talk about books you have not read. It’s been translated into English, so the excuse of not reading French, is, what they say, “poof !”.
First and most important, of course, is to have no sense of shame. Second, particularly if you have to talk with someone who has actually read the book, say, the author (ha! you’re in trouble now, huh!), the best approach is to talk about your ideas of what the book should be. You did take care of the first step, didn’t you ?
Okay, we know even without reading the book that we don’t have to read it to talk about it, but … it’s already on ? Why did they even bother to print any ?

The Illusion of Transparency
Thursday, October 25th, 2007
In searching for something about overcoming bias in the selection of experimental subjects, I came across this:
The illusion of transparancy
October 20, 2007
Illusion of Transparency: Why No One Understands You
In hindsight bias, people who know the outcome of a situation believe the outcome should have been easy to predict in advance. Knowing the outcome, we reinterpret the situation in light of that outcome. Even when warned, we can’t de-interpret to empathize with someone who doesn’t know what we know.
Closely related is the illusion of transparency: We always know what we mean by our words, and so we expect others to know it too. Reading our own writing, the intended interpretation falls easily into place, guided by our knowledge of what we really meant. It’s hard to empathize with someone who must interpret blindly, guided only by the words.
June recommends a restaurant to Mark; Mark dines there and discovers (a) unimpressive food and mediocre service (b) delicious food and impeccable service. Then Mark leaves the following message on June’s answering machine: “June, I just finished dinner at the restaurant you recommended, and I must say, it was marvelous, just marvelous.” Keysar (1994) presented a group of subjects with scenario (a), and 59% thought that Mark’s message was sarcastic and that Jane would perceive the sarcasm. Among other subjects, told scenario (b), only 3% thought that Jane would perceive Mark’s message as sarcastic. Keysar and Barr (2002) seem to indicate that an actual voice message was played back to the subjects.

Keysar (1998) showed that if subjects were told that the restaurant was horrible but that Mark wanted to conceal his response, they believed June would not perceive sarcasm in the (same) message:
“They were just as likely to predict that she would perceive sarcasm when he attempted to conceal his negative experience as when he had a positive experience and was truly sincere. So participants took Mark’s communicative intention as transparent. It was as if they assumed that June would perceive whatever intention Mark wanted her to perceive.”
(The above wording is from Keysar and Barr 2002.)
“The goose hangs high” is an archaic English idiom which has passed out of use in modern language. Keysar and Bly (1995) told one group of subjects that “the goose hangs high” meant that the future looks good; another group of subjects learned that “the goose hangs high” meant the future looks gloomy. Subjects were then asked which of these two meanings an uninformed listener would be more likely to attribute to the idiom. Each group thought that listeners would perceive the meaning presented as “standard”.
(Other idioms tested included “come the uncle over someone”, “to go by the board”, and “to lay out in lavender”. Ah, English, such a lovely language.)
Keysar and Henly (2002) tested the calibration of speakers: Would speakers underestimate, overestimate, or correctly estimate how often listeners understood them? Speakers were given ambiguous sentences (”The man is chasing a woman on a bicycle”) and disambiguating pictures (a man running after a cycling woman), then asked the speakers to utter the words in front of addressees, then asked speakers to estimate how many addressees understood the intended meaning. Speakers thought that they were understood in 72% of cases and were actually understood in 61% of cases. When addressees did not understand, speakers thought they did in 46% of cases; when addressees did understand, speakers thought they did not in only 12% of cases.
Additional subjects who overheard the explanation showed no such bias, expecting listeners to understand in only 56% of cases.
As Keysar and Barr (2002) note, two days before Germany’s attack on Poland, Chamberlain sent a letter intended to make it clear that Britain would fight if any invasion occurred. The letter, phrased in polite dipliomatese, was heard by Hitler as conciliatory - and the tanks rolled.
Be not too quick to blame those who misunderstand your perfectly clear sentences, spoken or written. Chances are, your words are more ambiguous than you think.

Google found the actual meanings of “the goose hangs high” (the future looks good), and the reason it means that (there is a goose in the larder, therefor you will not starve), and “to go by the board” (to be completely destroyed or overthrown), but not the reason behind it. What do “to come an uncle over someone” and “to lay out in lavender” mean?

I’ve heard things like this before. This is one reason why it’s a good idea to run your writing by someone else before you “publish”; you can get a better idea of whether what you wrote actually says what you wanted it to.

1) That’s why Deidre (then Donald) McCloskey wrote in (I believe), “The Rhetoric of Economics” (JEL 1983), that, “If the reader says something is unclear, it is unclear.”2) The recent Rush Limbaugh imbroglio is consistent with the point about inferring meaning. The political leanings of the commentors guided their inerpretation of his words.

Humor seems the most difficult. Once I taught a guy from Sweden English. One day he read an article in the newspaper to me and could tell me what it meant– no problem.When we got to the comics page… the humor didn’t translate at all.I still don’t know why the difference was so marked.

Certain kinds of academics use this to justify a rhetorical technique: they simply say they do not understand what you say, and they keep repeating this for any statements that do not fit with their standard method. For example, in a community uses formal statistical techniques, they say they cannot understand any argument for a probabilistic conclusion that is not expressed as a formal statistical test.

Robin, could you give a bit more detail?
Posted by: Scholar October 21, 2007 at 09:33 AM

I’d have to hear the voice mail message to believe what you’re saying. In my daily life, when one of my friends says, “That’s great. Just great” it’s totally clear whether he’s being sarcastic or not. Because he intends to sound sarcastic, and changes his inflection.
Now in this case the message was the same, so the inflection didn’t carry any content. But the subjects were told Mark was leaving a message for his friend. So it’s a reasonable assumption that Mark is using an inflection that his friend will recognize as sarcasm. I would assume that unless, as in the second case, they told me he was trying not to show sarcasm.
Posted by: Noumenon October 21, 2007 at 11:53 PM

Noumenon, one of the experiments (I think Keysar 1994) showed that, when people read in text that Mark left a voice message (that is, the experimental subjects themselves did not hear a spoken message, only read about Mark leaving one); or alternatively read in text that Mark left a written note; then they were equally likely to judge that June would identify sarcasm. In other words, the modality of text versus speech made no difference to their expectations.
Posted by: Eliezer Yudkowsky October 22, 2007 at 12:19 AM

Okay, then, that’s just weird. To me there’s obviously not enough information in a text message to tell sarcasm that way. Even a voice message wouldn’t be enough for someone who didn’t know Mark, like the restaurant manager.
I can’t really imagine myself in this scenario any more. My takeaway is that some people are dumb about text messages (or were in 1994 before the smiley).
Posted by: Noumenon October 22, 2007 at 03:03 AM

If they were told Mark left a voice message, it would be rational to assume June would identify sarcasm, because it would be rational to assume that Mark left it in a sarcastic tone (or not) if he intended sarcasm (or not). Though the written note case shows that’s not what’s really going on, unfortunately.

Hi Marty hereBack in the Bush we have many words to describe our environment that is mostly sand. The words are always the same but how we say the word describes what we mean example one click then word Danger under the sand maybe snake!Loud click then soft click then word slow rolling sand wind from the south face not good for hunting now. Click pop hand over our mouth then word means to hot for traveling best to go around. The word never changes or the meaning will be lost in enemy? Environment it is very important meaning is always understood life depends on meaning so I am confused about phone message Why not just say food was not good why leave meaning hanging to interpretation? This is not honest say the truth the person listening did not make the food so I say he should be honest. Or I, am I misunderstanding something in the article?
Posted by: Marty October 23, 2007 at 11:58 AM

I believe the reason for saying the opposite of what you mean is so that you and your friend can say, “We’re clever. Others would not perceive our nuanced tone and would stupidly think we meant what we said.” In the bush, don’t people sometimes make the sound for “snake” when there is no snake, just so they can laugh and mock the person who foolishly believed there was a snake?
Posted by: Noumenon October 23, 2007 at 01:35 PM

Chesh, lay out in lavender means “displayed in the best possible light” according to If you google “out in lavender” or “laid out in lavender”, you get more hits.
Posted by: Whit October 23, 2007 at 02:21 PM

Dear Whit, yes,when there is no real danger like at a party the youngsters may play everyone knowns it is harmless. Never in the bush this would be very bad manners to frighten for a laugh beside what pleasure is gained by such unkind act to me that is a foolish game and being mean is not showing cleverness. Marty

game theory in political science …

The New Nostradamus
Words By Michael A.M. LernerPhotos By Ethan Hill
Can a fringe branch of mathematics forecast the future? A special adviser to the CIA, Fortune 500 companies, and the U.S. Department of Defense certainly thinks so.
If you listen to Bruce Bueno de Mesquita, and a lot of people don’t, he’ll claim that mathematics can tell you the future. In fact, the professor says that a computer model he built and has perfected over the last 25 years can predict the outcome of virtually any international conflict, provided the basic input is accurate. What’s more, his predictions are alarmingly specific. His fans include at least one current presidential hopeful, a gaggle of Fortune 500 companies, the CIA, and the Department of Defense. Naturally, there is also no shortage of people less fond of his work. “Some people think Bruce is the most brilliant foreign policy analyst there is,” says one colleague. “Others think he’s a quack.”
Today, on a rare sunny summer day in San Francisco, Bueno de Mesquita appears to be neither. He’s relaxing in his stately home, answering my questions with exceeding politesse. Sunlight streams through the tall windows, the melodic sound of a French horn echoing from somewhere upstairs; his daughter, a musician in a symphony orchestra, is practicing for an upcoming recital. It’s all so complacent and genteel, which is exactly what Bueno de Mesquita isn’t. As if on cue, a question sets him off. “I found it to be offensive,” he says about a colleague’s critique of his work. “This is absolutely, totally, and utterly false,” he says about the attack of another.
The criticism rankles him, because, to his mind, the proof is right there on the page. “I’ve published a lot of forecasting papers over the years,” he says. “Papers that are about things that had not yet happened when the paper was published but would happen within some reasonable amount of time. There’s a track record that I can point to.” And indeed there is. Bueno de Mesquita has made a slew of uncannily accurate predictions—more than 2,000, on subjects ranging from the terrorist threat to America to the peace process in Northern Ireland—that would seem to prove him right.
“The days of the digital watch are numbered,” quipped Tom Stoppard. After spending a few hours with Bueno de Mesquita, you might come to believe that so is everything else. Numbered as in “mathematics”—more precisely, game theory, an esoteric branch of mathematics used to analyze interaction. “Game theory is math for how people behave strategically,” Bueno de Mesquita says.
Bueno de Mesquita has big ideas, and he’s more than happy to put his career on the line for them. Back in March 2004, when al-Qaeda bombed a Madrid train station, influencing the course of Spain’s general election three days later, a lot of U.S. security folks were nervous. Worried that al-Qaeda might try something similar here in the run-up to the November, 2004, presidential elections, the Pentagon hired Bueno de Mesquita to run some data through his forecasting model to tell them what to expect. The results were unequivocal. “I said there would be no homeland attack. I also indicated that bin Laden’s second-in-command, Ayman al-Zawahiri, would resurface around Thanksgiving, 2004,” he says. Just after the elections in November that year, Zawahiri released a new videotape. Bueno de Mesquita was right on both counts. “One of the things government needs most is advice that’s not wishy-washy. I try to be as precise as I can.”
For the record, this man is not some lunatic soothsayer sequestered in a musty, forgotten basement office. He is the chairman of New York University’s Department of Politics, a senior fellow at the Hoover Institution at Stanford, and the author of many weighty academic tomes. He regularly consults with the CIA and the Department of Defense—most recently on such hot-button topics as Iran and North Korea—and has a new book coming out in the fall that he cowrote with his pal Secretary of State Condoleezza Rice. His curriculum vitae, which details his various Ph.Ds, academic appointments, editorial-board memberships, writings, honors, awards, and grants, runs 17 small-font pages long.
He is wildly controversial, though. As one of the foremost scholars of game theory—or “rational choice,” as its political-science practitioners prefer to call it—Bueno de Mesquita is at the center of a raging hullabaloo that has taken over some of the most prestigious halls of learning in this country. Exclusive, highly complex mathematically, and messianic in its certainty of universal truths, rational-choice theory is not only changing the way political science is taught, but the way it’s defined.
To verify the accuracy of his model, the CIA set up a kind of forecasting face-off that pit predictions from his model against those of Langley’s more traditional in-house intelligence analysts and area specialists. “We tested Bueno de Mesquita’s model on scores of issues that were conducted in real time—that is, the forecasts were made before the events actually happened,” says Stanley Feder, a former high-level CIA analyst. “We found the model to be accurate 90 percent of the time,” he wrote. Another study evaluating Bueno de Mesquita’s real-time forecasts of 21 policy decisions in the European community concluded that “the probability that the predicted outcome was what indeed occurred was an astounding 97 percent.” What’s more, Bueno de Mesquita’s forecasts were much more detailed than those of the more traditional analysts. “The real issue is the specificity of the accuracy,” says Feder. “We found that DI (Directorate of National Intelligence) analyses, even when they were right, were vague compared to the model’s forecasts. To use an archery metaphor, if you hit the target, that’s great. But if you hit the bull’s eye—that’s amazing.”
How does Bueno de Mesquita do this? With mathematics. “You start with a set of assumptions, as you do with anything, but you do it in a formal, mathematical way,” he says. “You break them down as equations and work from there to see what follows logically from those assumptions.” The assumptions he’s talking about concern each actor’s motives. You configure those motives into equations that are, essentially, statements of logic based on a predictive theory of how people with those motives will behave. From there, you start building your mathematical model. You determine whether the predictive theory holds true by plugging in data, which are numbers derived from scales of preferences that you ascribe to each actor based on the various choices they face.
The Prisoner’s Dilemma, a basic in game theory, explains it well: Two burglars are apprehended near the scene of a crime and are interrogated separately by the police. The police know these two goons did it, but they don’t know how, so they offer each one a deal. If they both confess and cooperate, they’ll both get a minor sentence of five years. If neither man confesses, they’ll both only get one year (for having been caught with some of the stolen loot on them). But, and here’s where it gets interesting, if one confesses and the other doesn’t, the one who confesses walks out scot-free while the other will do 10 years. What will they do? Will they trust each other and do what’s obviously in their best interest, which is not confess? Based on game theory’s assumptions about human nature, the math derived from this dilemma tells you squarely that the two goons will turn each other in.
“In the foreboding world view of rational choice, everyone is a raging dirtbag.”
Which illustrates the next incontrovertible fact about game theory: In the foreboding world view of rational choice, everyone is a raging dirtbag. Bueno de Mesquita points to dictatorships to prove his point: “If you liberate people from the constraint of having to satisfy other people in order to advance themselves, people don’t do good things.” When analyzing a problem in international relations, Bueno de Mesquita doesn’t give a whit about the local culture, history, economy, or any of the other considerations that more traditional political scientists weigh. In fact, rational choicers like Bueno de Mesquita tend to view such traditional approaches with a condescension bordering on disdain. “One is the study of politics as an expression of personal opinion as opposed to political science,” he says dryly. His only concern is with what the political actors want, what they say they want (often two very different things), and how each of their various options will affect their career advancement. He feeds this data into his computer model and out pop the answers.
Though controversial in the academic world, Bueno de Mesquita and his model have proven quite popular in the private sector. In addition to his teaching responsibilities and consulting for the government, he also runs a successful private business, Mesquita & Roundell, with offices in Rockefeller Center. Advising some of the top companies in the country, he earns a tidy sum: Mesquita & Roundell’s minimum fee is $50,000 for a project that includes two issues. Most projects involve multiple issues. “I’m not selling my wisdom,” he says. “I’m selling a tool that can help them get better results. That tool is the model.”
“In the private sector, we deal with three areas: litigation, mergers and acquisitions, and regulation,” he says. “On average in litigation, we produce a settlement that is 40 percent better than what the attorneys think is the best that can be achieved.” While Bueno de Mesquita’s present client list is confidential, past clients include Union Carbide, which needed a little help in structuring its defense after its 1984 chemical-plant disaster in Bhopal, India, claimed the lives of an estimated 22,000 people; the giant accounting firm Arthur Andersen; and British Aerospace during its merger with GEC-Marconi.
But there are limits to what his company will do. For example, Bueno de Mesquita may already know, but he won’t say who’ll succeed George W. Bush in the White House. “We have a corporate policy that we will not, on a commercial basis, use the model in campaigns,” he says. “We don’t think it’s appropriate to manipulate the democratic process. We won’t take a client who wants to manipulate U.S. government policy, even if we agree with the manipulation. And we won’t take a foreign client whose objectives are contrary to the objectives of the United States government.”
There’s also the book he’s written with Condoleezza Rice and two other authors, The Strategy of Campaigning, which comes out in the fall. Given the Bush administration’s heavy ideological bent—which would seem to represent everything a rationalist like Bueno de Mesquita opposes—how does he justify putting his name on the same dust jacket as Rice’s? Bueno de Mesquita repositions himself in his chair. “The central question in this book is a question that Condi raised before she came to Washington,” he says. (So is her name there just to sell books? “We are making a concerted effort not to play up the fact that the Secretary of State is a co-author,” he later adds.)
Meanwhile, he has just launched and is the director of NYU’s Alexander Hamilton Center. “The mission for the center is the application of logic and evidence to solving fundamental policy problems. Not to a bipartisan solution, but to a nonpartisan solution.” In his continuing work for the CIA and the Defense Department, one of his most recent assignments has been North Korea and its nuclear program. His analysis starts from the premise that what Kim Jong Il cares most about is his political survival. As Bueno de Mesquita sees it, the principal reason for his nuclear program is to deter the United States from taking him out, by raising the costs of doing so. “The solution, then, lies in a mechanism that guarantees us that he not use these weapons and guarantees him that we not interfere with his political survival,” he says.
“They said my work was evil, offensive, that it should be suppressed. It was a very difficult time in my career.—Bruce Bueno de Mesquita”
Perhaps not coincidentally, the recent agreement that the United States reached with the government of Pyongyang closely resembles the one that Bueno de Mesquita’s model suggested: Kim agrees to dismantle his existing nuclear weapons but not his existing nuclear capability. “He puts it in mothballs with IAEA (International Atomic Energy Agency) inspectors on site 24 hours a day, 365 days a year. And in exchange, we provide him with $1.2 billion a year, which we label ‘foreign aid,’ of course.” The “foreign-aid” figure published in the newspapers was $400 million, which concerns Bueno de Mesquita. “I read that and I said, I hope that’s not the deal because it’s not enough money. He needs $1.2 billion, approximately, to sustain the loyalty of his cronies in the military and so forth. It’s unpleasant, this is a nasty man, but we’re stuck with it. The nice part of the deal is that it’s self-enforcing. Each side has a reason to credibly commit to their part of the deal.”
Recently, he’s applied his science to come up with some novel ideas on how to resolve the Israeli-Palestinian conflict. “In my view, it is a mistake to look for strategies that build mutual trust because it ain’t going to happen. Neither side has any reason to trust the other, for good reason,” he says. “Land for peace is an inherently flawed concept because it has a fundamental commitment problem. If I give you land on your promise of peace in the future, after you have the land, as the Israelis well know, it is very costly to take it back if you renege. You have an incentive to say, ‘You made a good step, it’s a gesture in the right direction, but I thought you were giving me more than this. I can’t give you peace just for this, it’s not enough.’ Conversely, if we have peace for land—you disarm, put down your weapons, and get rid of the threats to me and I will then give you the land—the reverse is true: I have no commitment to follow through. Once you’ve laid down your weapons, you have no threat.”
Bueno de Mesquita’s answer to this dilemma, which he discussed with the former Israeli prime minister and recently elected Labor leader Ehud Barak, is a formula that guarantees mutual incentives to cooperate. “In a peaceful world, what do the Palestinians anticipate will be their main source of economic viability? Tourism. This is what their own documents say. And, of course, the Israelis make a lot of money from tourism, and that revenue is very easy to track. As a starting point requiring no trust, no mutual cooperation, I would suggest that all tourist revenue be [divided by] a fixed formula based on the current population of the region, which is roughly 40 percent Palestinian, 60 percent Israeli. The money would go automatically to each side. Now, when there is violence, tourists don’t come. So the tourist revenue is automatically responsive to the level of violence on either side for both sides. You have an accounting firm that both sides agree to, you let the U.N. do it, whatever. It’s completely self-enforcing, it requires no cooperation except the initial agreement by the Israelis that they are going to turn this part of the revenue over, on a fixed formula based on population, to some international agency, and that’s that.”
His first foray into forecasting controversy took place in 1984, when he published an article in PS, the flagship journal of the American Political Science Association, predicting who would succeed Iran’s ruling Ayatollah Khomeini upon his death. He had developed a rudimentary forecasting model that was different from anything anyone had seen before in that it was not designed around one particular foreign-policy problem, but could be applied to any international conflict. “It was the first attempt at a general mathematical model of international conflict,” he says. His model predicted that upon Khomeini’s death, an ayatollah named Hojatolislam Khamenei and an obscure junior cleric named Akbar Hashemi Rafsanjani would emerge to lead the country together. At the time, Rafsanjani was so little known that his name had yet to appear in the New York Times.
Even more improbably, Khomeini had already designated his successor, and it was neither Ayatollah Khamenei nor Rafsanjani. Khomeini’s stature among Iran’s ruling clerics made it inconceivable that they would defy their leader’s choice. At the APSA meeting subsequent to the article’s publication, Bueno de Mesquita was roundly denounced as a quack by the Iran experts—a charlatan peddling voodoo mathematics. “They said I was an idiot, basically. They said my work was evil, offensive, that it should be suppressed,” he recalls. “It was a very difficult time in my career.” Five years later, when Khomeini died, lo and behold, Iran’s fractious ruling clerics chose Ayatollah Khamenei and Hashemi Rafsanjani to jointly lead the country. At the next APSA meeting, the man who had been Bueno de Mesquita’s most vocal detractor raised his hand and publicly apologized to him.
Bueno de Mesquita had arrived, and so, too, had rational-choice theory. Rational choicers began sprouting up in political-science departments around the country and, say their critics, strangling anyone and anything in their way. By 2000, according to one estimate, some 40 percent of all articles published in the prestigious American Political Science Review were rational-choice themed. Increasingly, graduate students in political science viewed a fluency in formal mathematic modeling as a prerequisite for career advancement. And the leaps in technology taking place only fueled rational choice’s advance: faster, more powerful computers allowed rational choicers to build bigger, ever more complex models that could be applied to ever more complex situations. And, naturally enough, an intellectual counteroffensive was launched.
It began in 1994 when two Yale political-science professors, Donald Green and Ian Shapiro, published their book, Pathologies of Rational Choice Theory, which disputed much of the scientific underpinnings that rational choice claimed for itself. In essence, the authors said that when rational choice was actually put to the practical test, much of it simply didn’t work. This was followed by a 1999 (lightning speed in academia) article by Stephen M. Walt in the journal International Security called “Rigor or Rigor Mortis?” Walt, a political-science professor at Harvard’s John F. Kennedy School of Government, conceded some value to formal modeling but ultimately likened rational choice to a “cult of irrelevance” that stifled creativity and had little practical value in actual policy formulation. Most vexing, Walt accused rational choicers of regarding nonrational choice theorists such as himself as “methodological Luddites whose opposition rests largely on ignorance.”
“We found that [national intelligence] analyses, even when they were right, were vague compared to [Bueno de Mesquita’s] forecasts. If you hit the target, that’s great. But if you hit the bull’s eye—that’s amazing.—Stanley Feder, former CIA analyst”
Since no one snaps a towel back harder than a scorned academic, Bueno de Mesquita and several of his rational-choice cohorts immediately mounted a blistering counter-counteroffensive, firing off a series of lengthy rebuttals to Walt’s piece that deconstructed his criticism, questioned his facts, and cited what was in their view Walt’s muddled logic as a prime example of why rational choice was so desperately needed in the field. “In the piece that Steve Walt wrote, in which he acknowledged that logical consistency was important, he also argued that it was overrated, that it stifled creativity. To me this is a bizarre idea,” says Bueno de Mesquita, “because really what that statement means to me is, if you relax logical consistency, you can say whatever you feel like and therefore you are back to a world in which the study of politics is the expression of personal opinion instead of being political science. It’s the art of politics or the articulation of beliefs, which is what dominates much of advising to government. It’s rhetoric.”
The brouhaha culminated at a raucous APSA meeting in 2001 at San Francisco’s Hilton Hotel with the open revolt of a group of major-league political scientists who, one by one, took to the podium to rail against rational choice and its encroaching methodological orthodoxy. Dubbed the “Perestroika Movement” by its anonymous founder (apparently, rational-choice folk are a powerful and vindictive lot), the dissident group vowed to take a stand against “the domination of mathematical approaches to the discipline.” There is a “hegemonic threat out there,” warned John J. Mearsheimer, a noted professor of international relations at the University of Chicago. “This is about the mathematicization of political science,” he said. “I’m in favor of filling the zoo with all kinds of animals. But I’m concerned about them running us out of the business or making us marginal.” Ultimately, the Perestroikans did win some concessions: a new editor of the APSR who vowed to make the flagship journal more hospitable to mathematics-free articles and a pledge from the APSA to open up its method of appointing officers. “The APSA had become dominated by those practicing so-called rigorous analyses,” says Walt. “Now the pendulum has swung back a bit.”
For Bueno de Mesquita, getting his methodology accepted by the policy-making establishment remains somewhat of an uphill slog. The most pointed criticism of rational choice has been that, unlike with more traditional political scientists, very little cross-pollination takes place between rational-choice academics and government policy-makers. Bueno de Mesquita says it’s just a matter of time before that changes. “Because people who are in a position to appoint people weren’t trained in this way, they don’t feel as comfortable as with people who were trained in what I would describe as a less rigorous form of study of politics. And, so, the folks who do more rigorous work typically don’t get invited in,” he says. Of course, the same was true of economics 40 years ago when nontechnical types like John Kenneth Galbraith dominated the field. Paul Samuelson and Milton Friedman changed all that, and Bueno de Mesquita sees himself playing the same role for politics.
Bueno de Mesquita remains unfazed, ever certain that rational choice will ultimately prevail. “When I moved to Rochester in 1973, if you wanted to be trained in this kind of political science, you could go to Rochester, period,” he says. “Ten years later, you could go to Rochester, Caltech, and Washington University in St. Louis. If you asked me today, you could go to the places I just mentioned, and you could go to NYU, you could go to Stanford—there’s a long list of places you could go. Except, of course, Harvard. But it will happen there, too. I’m on their syllabus.”

Bad sports / Why people cheat when they don’t have to

Bad sportsWhy people cheat when they don’t have to
By Drake Bennett September 23, 2007
IT’S BEEN A tough month for fair play in New England.
Three weeks ago, a police prosecutor in Hanover, N.H., announced that he might bring felony charges against nine students accused of breaking into their high school to steal advance copies of AP exams. The taping scandal that engulfed the New England Patriots after their season opener was finally resolved last week, with no penalties beyond the $750,000 in fines and probable loss of a first-round draft pick. And the Patriots remain without safety Rodney Harrison, suspended until Oct. 2 for violating the league’s policy on performance-enhancing drugs.
All of which has left people scratching their heads. Why would smart students steal a test? Why would the favorites to win the Super Bowl break a rule, especially when they had already been warned about the behavior? Why, in other words, do people cheat in situations where there is little to gain - one good grade, a slight edge in a game - and so much to lose?
This irrationality may be the rule, rather than the exception, when it comes to cheating, according to a group of scholars who have turned their attention to the mysteries of the cheating mind. Cheating is often thought of as something that is done after cold calculation. But, the new research has found, people are prone to cheat even when it is not in their best interest. Instead of carefully weighing the costs and benefits of breaking the rules, people can be heavily swayed by peer pressure, their mood, their image of themselves. Sometimes, people even cheat out of a sense of fairness.
“A lot of the time people are thinking about the broader costs and benefits, but there are biases or blind spots or other psychological factors that are actually driving their behavior,” says Maurice Schweitzer, an associate professor at the University of Pennsylvania’s Wharton School who studies deception.
The new research into the psychology of cheating comes at a time when others, largely economists, are finding stark evidence that cheating is a widespread part of sports, and not merely in the sort of cases that make the news. Using economics as a forensic tool, they’re arguing that foul play, either by referees or players, is common in sports as varied as figure skating, basketball, and sumo wrestling.
Whether it’s corporate malfeasance, academic dishonesty, tax fraud, or point shaving, researchers are looking with renewed interest at the motivations behind breaking the rules - and whether we fully understand what we’re doing when we do it. Cheating has always interested social scientists, but increasingly today they’re trying to find ways around the secrecy and obfuscation that surrounds cheating, and designing experiments that expose telltale patterns.
Economists who have looked specifically at sports argue that their work is more than just an investigation of games, but a window into the workings of the human mind. They see their field as promising in large part because sports and games serve as ready-made experiments - people competing on roughly equal terms, under agreed-upon rules, for the same clear, quantifiable goals - with the potential to yield insights into how we live the rest of our lives.
“It’s a metaphor,” says Justin Wolfers, an assistant professor at the Wharton School who has looked at point shaving in college basketball. “The data are plentiful, and we can have very sharp predictions and test them. And the lessons, hopefully, are generalizable.”
. . .
Even setting aside the Patriots, any sports fan could reel off a list of recent cheating scandals: the doping revelations in professional cycling and baseball; Tim Donaghy, the NBA referee who admitted to betting on games he worked; and, last year, match fixing in Italian professional soccer involving some of the most storied teams in Europe.
But if economists like Wolfers are to be believed, cheating is more widespread than we hear about. Wolfers looked at the scores of more than 44,000 Division 1 college basketball games from 1989 to 2005 and found that the number of times that the winning team just failed to beat the “spread,” the expected margin of victory as determined by Las Vegas bookmakers, couldn’t be explained by chance. More likely, he argues, players on the winning team were holding back just a little bit. They would still win, but so would gamblers who had bet against the spread - and who, Wolfers surmised, had colluded with the players beforehand. Wolfers found that 5 percent of the games with large spreads showed this sort of suspicious score.
Perhaps the best-known study of this kind was by Steven Levitt, an economics professor at the University of Chicago and co-author of the best-selling book “Freakonomics,” who looked at match fixing in sumo wrestling. But in recent years other economists have started doing work to uncover sports cheating - some instances more intentional than others. Eric Zitzewitz, an associate professor of economics at Dartmouth, has found evidence of vote trading among figure skating judges in the Olympics. Luis Garicano and Canice Prendergast of the University of Chicago, along with Ignacio Palacios-Huerta of Brown University, have looked at systematic favoritism among Spanish soccer referees.
Paradoxically, one of the most powerful motivations for cheating, according to scholars who study decision-making, is a desire for fairness. In the past couple weeks, on New England sports blogs and radio shows, the most widely heard justification for the Patriots cheating was that other teams in the league were almost certainly doing the same thing. Professional cyclists describe similar pressures to take performance-enhancing drugs - a complaint only strengthened by the recent confirmation of Tour de France champion Floyd Landis’s positive drug test.
In a way, this is common sense: If an opponent is illegally gaining some advantage over me, I’ll want to balance things out. But what’s more surprising is the way the effect extends beyond situations in which cheating confers an advantage. Robert Kurzban, a psychologist at the University of Pennsylvania, has found that players in a game he created are less likely to behave selfishly when they know that other players aren’t behaving selfishly, even though being the only player to behave selfishly actually increases one’s winnings at the game. That would suggest that most people, if they could be assured no one else was cheating, would be content not to cheat.
Daylian Cain, an assistant professor specializing in decision-making at the Yale School of Management, believes that the “defensive” model explains much of the cheating one sees in professional sports. Since coaches and players can’t know what opponents are doing, they “tend to think that others are doing what they are doing and thinking what they are thinking,” he says. “You think you were doing things for a reason, and assume other people have the same reasons, so you think it’s likely that they’re cheating.”
Findings like these emerge from a broader wave of social science research looking at the ways in which we calculate - and miscalculate - costs and benefits in making decisions, whether it’s a coach choosing to go for it on fourth down or a head of state choosing to go to war. And while the idea of defensive cheating emerges from a new model of how people react to incentives, other research is looking at the complicated, sometimes conflicting ways in which we think about costs.
In particular, people seem willing in some cases to simply ignore the cost of getting caught. In a set of experiments carried out in 2005 by the economists Nina Mazar and Dan Ariely, of MIT, and On Amir, a marketing expert at the University of California at San Diego, subjects were given a timed test of general-knowledge questions and paid for each correct answer. They varied the setup of the experiment and found that people would tend to cheat when given the chance, but that the risk of being discovered did not deter them. Even more surprisingly, the experimenters found a way to limit cheating that had nothing to do with the threat of getting caught. When they asked subjects to write down as many of the Ten Commandments as they could remember before taking the test, it virtually eliminated cheating.
Researchers are only beginning to understand what shapes the propensity to cheat, but some economists believe more answers will come from looking directly at the brain, says Colin Camerer, an economics professor at the California Institute of Technology who is involved with the research. In the meantime, researchers, like the rest of us, can only speculate about the famously tight-lipped Bill Belichick’s motives. But if they’re right, even the coach may be unsure of why he did what he did.

my horoscope
Wednesday, August 29th, 2007
I hardly ever read my horoscope anymore, but today it was rather a surprise:
”You’ll not be yourself today, so don’t think that everyone around you is wrong. It’s probably you who is causing all the fuss. Keep things simple, avoid controversial subjects and don’t let anyone bait you into a battle.”
outsourcing intelligence, the erosion of loyalty and citizenship

Outsourcing intelligenceBy James Carroll August 27, 2007
THE WAYS in which the Bush war has degraded the structures and culture of Iraq are obvious. Less so are its insidious effects on the United States, but President Bush is similarly destroying something essential to our own democracy. A signal of that was sounded last week when The Washington Post reported that the Defense Intelligence Agency is transferring “core intelligence tasks of analysis and collection” to private contractors — up to a billion dollars worth. This raises the prospect that hired guns, instead of sworn officials, will be conducting covert operations, spying missions, interrogations, “renditions,” surveillance — the whole dangerous complex of shadow activity that began as the government’s most sensitive responsibility.
Given the often shocking record of what US intelligence officials have done over the years, why does it matter if such activities are carried out by contractors? The answer patently goes to the question of accountability. Public servants who are bound by oaths to the Constitution and the law understand what the measure of behavior must be, even if they fall short of it. Activities involving the surreptitious, especially, have properly been reserved to public institutions subject to political oversight. Private parties, bound by contract, operate at remove from such limit and accountability, which may be why borderline activities like interrogation or rendition are increasingly farmed out to them.
But there is a deeper problem. I know the dark history well, yet I also know that the American intelligence services were founded, then staffed across two generations, by patriots — people who acted primarily out of loyalty to this country. If at times they acted wrongly, they mainly did so with a sense of higher purpose. Among the most gifted and well educated people in government, intelligence officials could always have done better in the private sector, but personal gain was never the point. The ethos of service informed their commitment. That was broadly true of the military, which is why “service” is its synonym. But that word, as in “secret service,” defined the essence of the government’s most dangerous work — dangers both physical and moral.
But now intelligence activities, like security functions in Iraq, are increasingly carried out for the sake of large paychecks. True belief has its problems, but so does the no-belief of greed. The Post reported that “outsourced” intelligence operatives cost, on average, twice what comparable government employees are paid. This has resulted in something new — the resignations of trained and trusted officials who take jobs with contractors to perform the same operations, but with far higher pay. Whether their activities are different or not, they themselves are. Such ex-officials are dismantling politically accountable structures, and undercutting an ideal of selflessness that formerly made the custodians of state power its most important check.
Readers of this column may know that the Defense Intelligence Agency was founded by my father in 1961. Not long before, he had declined an offer from the Ford Motor Company to take a big job in Detroit, a chance at true affluence. My parents were typical products of immigrant culture, people who so loved America for its welcome that the highest privilege they could imagine was to spend their lives in its service. In this, newcomers were like the “best and brightest” of the establishment — the patriots who first stamped the culture of American intelligence. I know for certain that, in setting out the ethos of the DIA, my father assumed love of country, and sacrifice for it, as foundational. He would not have entrusted the difficult and, perhaps, dirty work for which he found himself responsible to people who thought differently. Profit-driven contractors for core functions of the agency? My father would not have understood what you were talking about.
As the Post suggests, the Bush administration has replaced officials with contractors throughout government, outsourcing run amok. But Bush did not begin this. Since Ronald Reagan, conservatives have preached the doctrine that the nation’s basic needs can best be met by private enterprise. The profit motive trumps any public ideal. Consequently, government has been in slow motion collapse, with the ineptitudes of Iraq as final proof of its untrustworthiness.
But what the antigovernment movement missed is that attacks on the public sector equal assaults on the public. When the high calling of public service yields to the highest bid, the corruption is total: the heart of government — the military — becomes mercenary; the mind of the military — intelligence — becomes privatized. Citizenship itself is universally gutted, yet another source of our malaise.

fMRI - detecting “switchers” and “stickers”
Tuesday, August 21st, 2007
from: A Beautiful Math by Tom Siegfried (Joseph Henry Press, 2006)In one experiment described by Montague and Berns, people chose either A or B on a computer screen and then watched a bar on the screen to see whether their choice earned a reward. (The bar recorded accumulated reward “points” as the game progressed.) As the game went on, the computer adjusted the rewards, based on the player’s choices. At first, choosing A raised the bar more, but choosing A too often made B a better bet. When A’s payoffs dropped, some players noticed right away and quickly switched to choosing B more often. But others stuck with A, gambling that it would return to its previous high-payoff rate. It appeared that some brains are more inclined to take risks than others — some players play conservatively; others are risk-takers.
To me, it sounds more like they should be called “switchers” and “stickers”. But the labels don’t really matter. The most intriguiging result from this experiment is the revelations from the brain scans. Sure enough, patterns of brain activity differed in the two groups, particularly in a small clump of brain cells called the nucleus accembens. It’s a brain region implicated in drug addition, and it’s more active in the “risk-taking” game players (the stickers).
The neatest thing, though, is that you can tell who the risk takers and play-it-safers are from their brain scans just after the very beginning of the game, even while their behaviors are still identical.

The folly of 1 percent policy
By Eugene Declercq and Judy Norsigian August 6, 2007
THE PHRASE that comes to mind when you hear Dick Cheney is probably not “reshaping American childbirth.” Yet Vice President Cheney’s “One Percent Doctrine” — the title of Ron Suskind’s 2006 book on post9/11 national security policy — perfectly captures an approach to decision-making in American medicine that misallocates resources and undermines primary care. By focusing maximum resources on preventing an extremely rare but potentially disastrous outcome over necessary preventive care, this model has shaped healthcare decision-making in areas ranging from hysterectomies to coronary bypasses. One shift — the rapidly rising caesarean rate — exemplifies this problem.Suskind reports that in debates over national security policy following 9/11, Cheney repeatedly invoked the principle that if there’s even a 1 percent chance of a terrorist attack, we must prepare as if it were a certainty. This extreme position invariably gave Cheney the moral high ground in debates, where he could appear more willing to protect American interests than others with a broader focus. Of course, in winning the immediate argument, Cheney also ignored myriad longer-term complications involving problems not solved while the “emergency” is addressed.
In healthcare, caesarean sections represent the most recent example of this doctrine, as births are increasingly treated as potential emergencies requiring expensive, high-tech interventions. The caesarean rate in the United States has increased from 20 percent in 1996 to a record high of more than 30 percent in 2005, trailing only Italy (37 percent) and South Korea (35 percent) among industrialized countries. Obstetricians are more skilled at performing caesareans than ever before and caesareans are safer than ever. But they are not without negative consequences. When they are performed as elective surgery on mothers with little or no medical risk, these harms outweigh the benefits.
Yet caesareans are advocated as necessary to avert potential disasters that might occur. At a 2006 meeting sponsored by the National Institutes of Health, one doctor captured the 1 percent (or in this case 1/30th of 1 percent) doctrine when he described rare conditions and noted the benefits of a 100 percent caesarean rate (you read that right) in avoiding these outcomes in 3 in 10,000 cases.
Likewise, a 2006 position statement from the American College of Obstetricians and Gynecologists states that “Labor and delivery is a physiologic process that most women experience without complications,” but then goes on to emphasize the 1 percent doctrine: “. . . serious intrapartum complications may arise with little or no warning, even in low risk pregnancies.” The statement and the doctor’s claim are true, of course — anything can occur — but does that mean that society benefits when every birth is handled as a disaster (or worse yet a lawsuit) waiting to happen?
No one wishes a health problem on any mother or child, but the “1 percent” advocates of higher caesarean section rates assert they care more about infant outcomes than those who oppose them. However, the consequences of universal caesarean sections on a largely healthy population are profound in both the short run (longer recovery, greater postpartum pain, higher maternal rehospitalization rates for surgical complications, higher costs) and long run (higher rates of subsequent stillbirths, greater risk of future uterine rupture, longer stays requiring more hospital space). The 1 percent doctrine cares little about such consequences since its focus is on winning the current argument.
Creating a crisis atmosphere is essential to the 1 percent doctrine and its ability to override all obstacles — be they constitutional restrictions on national security measures or concerns about the United States ranking last among industrialized countries on infant mortality. Such an atmosphere encourages more centralized decision-making and stifles debate. The fact that most of these crises never occur and that countless resources are expended to prevent something that was unlikely to happen anyway is lost in the relief of the immediate positive outcome (a healthy baby or no terrorist attack). In the long run, however, we’ve wasted time and money, created new problems, and ignored systematically documented, if less emotional, evidence.
A version of the 1 percent doctrine has been invoked for decades in steering the US healthcare system away from an emphasis on preventive care for the whole population to an obsession with treating rare events. As a debating strategy, the 1 percent doctrine is extremely persuasive. As a policy guideline, it makes no sense in either politics or healthcare.

Miscellaneous posts in between have been cleaned out. Back to a new start on the burdenon society. An outlet for ideas.
Sunday, August 5th, 2007
Classification into simple groups so we can summarize and deal with “things-that-are-alike” rather than isolated incidents or objects. Presumably Plato did this to impose some sort of order on an already complex universe. We continue to follow that tradition because without classification and summarization, we would not be able to find “rules” of behavior.
But classification and finding rules of behavior, works in places where the normal bell-curve random distribution applies. In some areas, the standard distribution with standard deviations, don’t work. Not only in circumstances with asymmetric outcomes (turn left, you merely continue to be lost - turn right, you run off the cliff and fall 200 feet to a pile of rocks) do the “normal” distribution fail, but in particular the “black swan” event, which doesn’t even fit into a distribution, will cause massive consequences.
Bertrand Russell’s chicken
Sunday, August 5th, 2007
Taleb tells the story of a chicken (today, in the US, we would use a turkey), which for a thousand days is fed and cared for by humans. Until that thousand-and-one day, which is the Wednesday before Thanksgiving. Ha ! All the history observed by that chicken or turkey, is for naught. The entire performance over a thousand days suddenly gets sidetracked by a surprising event. Now if you were the farmer, you know this is going to happen.
The entire past history of behavior, is absolutely useless in dealing with this type of event, unless you can understand the motive of the farmer. If you were a really smart turkey, you figure this out and arrange to be the one pardoned by the Prez to live out your life away from the hatchet.
9/11 could be seen as Thanksgiving.
Black Monday, October 19th, 1987, could be seen as the same type of event.
So could the sinking of the Titanic.

The Black Swan
Sunday, August 5th, 2007
Taleb’s new book “The Black Swan - The Impact of the Highly Improbable”, points out three sources of opacity between the human brain and history (or even our own life experiences).

a. the illusion of understanding …
b. the retrospective distorton … in hindsight, events have been put into their proper context and explanations …
c. the overvaluation of factual information and the handicap of authoritative and learned people.
The more I learn, the more I am firmly convinced that I know almost nothing.
The Narrative Fallacy
Sunday, August 5th, 2007
or, the story-telling imperative. Telling the story puts things into an organized structure which can be remembered. But the story simplifies, categorizes, Platonizes, and forces the world into an artificial (?) structure that perhaps does not acknowlege the possibility of the existence of things outside the simplification.

the ingratitude factor

when you warn people about something abstract, particularly an event or possible outcome that never becomes realized, or act in their interest to prevent a disaster, their common response is, why are you wasting my time and money ?

p 26, Fooled by Randomness
David Hume and the Cygnus Atratus
Sunday, June 17th, 2007
The Scots philosopher: “No amount of observations of white swans can allow the inference that all swans are white, but the observation of a single black swan is sufficient to refute that conclusion.”
Hume is the first modern epistemologist. They who stress the need for rigor in the gathering and interpretation of knowledge.
I’ve mentioned before, the very fact that I know absolutely nothing about a subject, liberates me to make all manner of pronouncements on a topic, pretending to be an expert on such. Wide sweeping generalizations, misinterpretations, are all part of the package.
Pure empiricism without logical structure, is dangerous.

The Hidden Role of Chance in Life and in the Markets, by Nassim Nicholas Taleb.
Starting to read 2nd ed., it took me a long time to get past the introductory parts (preface, etc.), because I kept getting caught by little gems of statements. Examples (okay you don’t have to agree, the differences among us make life interesting):
“Aut tace aut loquere meliora silencio (only when the words outperform silence).” That is a brave man, I thought - many times I know perfectly well I should shut up, or stop writing, but an inability to just stop while I’m ahead, is difficult for me. I excuse it only by the weak rationale of desiring completeness, but it is a weak excuse.
“Past events will always look less random than they were (it is called the hindsight bias).” “backfit explanations concocted ex post by his deluded mind”Montaigne vs Descartes -vague and informal (but critical) judgement vs formal thinking seeking logical certitude
something about which I have no iota of clue: “Hume’s Problem of Induction (or Aristotle’s inference to the general)” Ultimately, what do we know ?
Errors in interpretation abound — not understanding the differences between, coincidence and causality.
“It is a mistake to use … statustics without logic, but … is not a mistake to use logic without statistics.” Reminds me of the book “how to lie with statistics” …
“the classical ‘expert problem’ with the buildup of rules of thumb that do not have empirical validity?” — let’s examine our assumptions always.
“This book is about luck disguised and perceived as nonluck (that is, skills) and, more generally, randomness disguised and perceived as non-randomness (that is, determinism).” It seems that humans are terrible at estimating probability.
“Delivering advice assumes that our cognitive apparatus rather than our emotional machinery exerts some meaningful control over our actions.” Now that is a level of randomness, or attribution of what really exerts meaningful control over our actions. If it is not our cognitive apparatus, …

A Surgeon’s Notes on Performance.
Always try to do better. For those in the medical profession, better can mean the difference between life and death. But it can be a guiding principle in all life pursuits.
Atul Gawande makes some suggestions at the end:
1) Ask an unscripted question. Something that establishes a personal connection between yourself and other(s). Without that personal connection, it is too easy to treat people as objects.
2) Don’t complain. “It’s boring, it doesn’t solve anything, and it will get you down.”
3) Count something. Measure something about the universe in which you live and breathe. When you have counted, you can measure and analyze trends.
4) Write something. It is an attempt to observe and document, or observe and remember, something special about your world.
5) Change. Look to be better.
In a universe dominated by the bell curve, it is the “positive deviants” who pull the average in a direction that is beneficial to the rest, by becomine one of those deviations.

The Power of a Positive No
Monday, May 28th, 2007
How to say NO and still get to YES. William Ury, Bantam Books, March 2007.ISBN-13:978-0-553-80498-0.
Say no served up between two yes’s. The first yes is the root of your value system - for example, that you value your family’s time and family life. When you get to the part where you have to say no to your boss about working double shifts all weekend, that first statement of value establishes the context that you are not refusing because you are a recalcitrant employee. The final yes opens options — can we get Frank to take a shift, or Jim ? Can some of the work be covered during the week ? Ury says, the first yes forms the root of your position — the deeper and more conviction with which you can say that first yes, affirms the no that follows — that is the trunk of the “tree” — and the last yes, are the branches that grow out and permit new options and relationships.
Go in with a “Plan B”, not just BATNA (the best alternative to a negotiated agreement) because you may not get to ANY agreement. If you have a solid Plan B, the very existence of that plan will give you a level of confidence that cannot help but make you negotiate from a role with greater power.
Sometimes our values are so obvious that they do not need to be stated out loud. But not actually stating them in clear (non-weasel) language can be very affirming. So many “mission statements” are fuzzy and loosely stated, they leave options to avoid the responsibility implied by some words. There is a universe of difference between “should” and “must”.
Reminds me I should look for Dale Carnegie’s classic and see what he says.
