Challenging the assertion that the key to life is low expectations: Some people believe the secret to happiness is low expectations.

Research shows that whatever the outcome, whether we succeed or we fail, people with high expectations tend to feel better.

We wear rose-tinted glasses whether we are eight or eighty.

Although the belief in a better future is often an illusion, optimism has clear benefits in the present. Hope keeps our minds at ease, lowers stress, and improves physical health. This is probably the most surprising benefit of optimism.

Yes, optimism is on one level irrational and can also lead to unwanted outcomes.

She became a science journalist. At first it was a lark, a way to get free press passes to conferences where she and her father could ask questions of the greatest minds in quantum mechanics, string theory and cosmology. But within a short time, as she started getting assignments, journalism became a calling, and an identity.

“If observers create reality, where do the observers come from?” But the great man responded in riddles. “The universe is a self-­excited circuit,” Wheeler said. “The boundary of a boundary is zero.” The unraveling of these mysteries propels the next 400 or so pages.

she has an epiphany — that for something to be real, it must be invariant — she flies home to share it with her father. They discuss her insight over breakfast at a neighborhood haunt, where they make a list on what they will affectionately call “the IHOP napkin.” They list all the possible “ingredients of ultimate reality,” planning to test each item for whether it is “real,” that is whether it is invariant and can exist in the absence of an observer.

their readings and interviews reveal that each item in turn is observer-dependent. Space? Observer-dependent, and therefore not real. Gravity, electromagnetism, angular momentum? No, no, and no. In the end, every putative “ingredient of ultimate reality” is eliminated, including one they hadn’t even bothered to put on the list because it seemed weird to: reality itself

What remained was an unsettling and essential insight: that “physics isn’t the machinery behind the workings of the world; physics is the machinery behind the illusion that there is a world.”

In the proposal, she clarifies how cosmology and quantum mechanics have evolved as scientists come to grips with the fact that things they had taken to be real — quantum particles, space-time, gravity, dimension — turn out to be ­observer-dependent.

Mr. Putin’s decisions since the crisis began reflect instincts, political skills and emotions that have characterized his 14 years as Russia’s paramount leader, including a penchant for secrecy, loyalty and respect, for him and for Russia. They also suggest a deepening frustration with other world leaders that has left him impervious to threats of sanctions or international isolation

Because of Mr. Putin’s centralized authority, Russia’s policies and actions in moments of crisis can appear confused or hesitant until Mr. Putin himself decides on a course of action

Mr. Putin, by his own account at a news conference on Tuesday, warned Mr. Yanukovych not to withdraw the government’s security forces from Kiev, one of the demands of the agreement being negotiated.

By the next day, however, Ukraine’s Parliament had stripped Mr. Yanukovych of his powers, voted to release the opposition leader Yulia V. Tymoshenko from prison and scheduled new presidential elections. Russia’s initial response was muted, but officials have since said that Mr. Putin fumed that the Europeans who had mediated the agreement did nothing to enforce it.

The group, the officials and analysts said, included Sergei B. Ivanov, Mr. Putin’s chief of staff; Nikolai P. Patrushev, the secretary of the security council; and Aleksandr V. Bortnikov, the director of the Federal Security Service. All are veterans of the K.G.B., specifically colleagues of Mr. Putin’s when he served in the organization in Leningrad, now St. Petersburg, during the 1970s and ’80s.

“He has bit by bit winnowed out the people who challenged his worldview,” Mr. Galeotti said.

The deployment of the Russian forces — which the Ukrainian government has said ranged from 6,000 to 15,000 troops — remains a covert operation, the officials and analysts said, to sidestep international law and the need for approval by the United Nations Security Council, something that Mr. Putin and others have repeatedly insisted was necessary for any military operations against another country.

As long ago as 2008, when NATO leaders met in Bucharest to consider whether to invite Ukraine to begin moving toward membership, Mr. Putin bluntly warned that such membership would be unacceptable to Russia, presaging the strategy that appears to be unfolding now.

The author retorts “I really have an issue with the word hoax.” He regards himself as a performance artist. His response – “It’s the people who reported it who are deceiving their audience.”

Why is fake news so popular on newssites? Here are two reasons: first, it provides emotional “buzz.” Second, because it can make a lot of money. As the Washington Bureau chief of the Pulitzer winning Huffington Post lamented, “If you throw something up without fact checking it, and you’re the first one to put it up, and you get millions and millions of views, and later it’s proved false, you still got those views. That’s a problem. The incentives are all wrong.”Especially when, as at places like Bloomberg, remuneration is based on the number of hits an article receives. But incentives are wrong not just for news gathering organizations.

Americans continue to believe important historical “facts” that are untrue. After 9/11, Americans were incensed to hear that the many in the Middle East thought Osama bin Laden’s horrifying attack was the product of a CIA-Mossad plot. To this day, large majorities in countries like Pakistan think the massacre of 9/11 was created in Washington or Tel Aviv.

Yet close to a majority of Americans believe that Saddam Hussein, tyrant of Iraq, was in cahoots with Al-Qaeda, especially before the 9/11 attack. The Bush administration told them so.Which people in the Middle East rightly regard as preposterous.Saddam Hussein was the leader of a boldly secular, Arabist tyranny. Sunni fanatics like Al Qaeda were his regime’s blood enemies. That they would work together rather than murder each other was just insane. Welcome to the world of fict and faction.

What can we learn from this? Plausibility is not truth; when something is “too good to be true” it generally isn’t; institutions increasingly do not back up what they proclaim and sell.And the “free informational marketplace” of the Internet is a wonderful site for fraud, scams, lies, plausible lies, and pleasant, beautiful untruths. So we all need our own truth detectors.

beauty is very much about familiarity and it’s reinforcing an idea we have already. It’s like when we go on holiday, all we really want to do is take the photograph that we’ve seen in the brochure. Because our idea of beauty is constructed, by family, friends, education, nationality, race, religion, politics, all these things

I have found the 21st-century version of the Venetian secret and it is a mathematical formula. What you do, you get a half-decent, non-offensive kind of idea, then you times it by the number of studio assistants, and then you divide it with an ambitious art dealer, and that equals number of oligarchs and hedge fund managers in the world.

the nearest we have to an empirical measure of art that actually does exist is the market. By that reckoning, Cézanne’s “Card Players” is the most beautiful lovely painting in the world. I find it a little bit clunky-kitsch but that’s me. It’s worth $260m.

The opposite arguments are that it’s art for art’s sake and that’s a very idealistic position to take. Clement Greenberg, a famous art critic in the 1950s, said that art will always be tied to money by an umbilical cord of gold, either state money or market money. I’m pragmatic about it: one of my favourite quotes is you’ll never have a good art career unless your work fits into the elevator of a New York apartment block.

there’s one thing about that red painting that ends up in Sotheby’s. It’s not just any old red painting. It is a painting that has been validated. This is an important word in the art world and the big question is: who validates? There is quite a cast of characters in this validation chorus that will kind of decide what is good art. They are a kind of panel, if you like, that decides on what is good quality, what are we going to end up looking at?

They include artists, teachers, dealers, collectors, critics, curators, the media, even the public maybe. And they form this lovely consensus around what is good art.

there were four stages to the rise of an artist. Peers, serious critics and collectors, dealers, then the public.

Another member of that cast of validating characters is the collectors. In the 1990s, if Charles Saatchi just put his foot over the threshold of your exhibition, that was it. The media was agog and he would come in and Hoover it up. You do want the heavyweight collector to buy your work because that gives it kudos. You don’t want a tacky one who is just buying it to glitz up their hallway.

The next part of this chorus of validation are the dealers. A good dealer brand has a very powerful effect on the reputation of the artist; they form a part of placing the work. This is a slightly mysterious process that many people don’t quite understand but a dealer will choose where your work goes so it gains the brownie points, so the buzz around it goes up.

now, of course, galleries like the Tate Modern want a big name because visitor numbers, in a way, are another empirical measure of quality. So perhaps at the top of the tree of the validation cast are the curators, and in the past century they have probably become the most powerful giver-outers of brownie points in the art world.

ach of the encounters with these members of the cast of validation bestows upon the work, and on the artist, a patina, and what makes that patina is all these hundreds of little conversations and reviews and the good prices over time. These are the filters that pass a work of art through into the canon.

So what does this lovely consensus, that all these people are bestowing on this artwork, that anoints it with the quality that we all want, boil down to? I think in many ways what it boils down to is seriousness. That’s the most valued currency in the art world.

The whole idea of quality now seems to be contested, as if you’re buying into the language of the elite by saying, “Oh, that’s very good.” How you might judge this work is really problematic because to say it’s not beautiful is to put the wrong kind of criteria on it. You might say, “Oh, it’s dull!” [And people will say] “Oh, you’re just not understanding it with the right terms.” So I think, “Well, how do we judge these things?” Because a lot of them are quite politicised. There’s quite a right-on element to them, so do we judge them on how ethical they are, or how politically right-on they are?

What I am attempting to explain is how the art we see in museums and in galleries around the world, and in biennales – how it ends up there, how it gets chosen. In the end, if enough of the right people think it’s good, that’s all there is to it. But, as Alan Bennett said when he was a trustee of the National Gallery, they should put a big sign up outside saying: “You don’t have to like it all.”

Or then again I might say, “Well, what do I judge them against?” Do I judge them against government policy? Do I judge them against reality TV? Because that does participation very well. So, in the end, what do we do? What happens to this sort of art when it doesn’t have validation? What is it left with? It’s left with popularity.

Then, of course, the next group of people we might think about in deciding what is good art is the public. Since the mid-1990s, art has got a lot more media attention. But popularity has always been a quite dodgy quality [to have]. The highbrow critics will say, “Oh, he’s a bit of a celebrity,” and they turn their noses up about people who are well known to the public

it is not clear whether the rise of post-war tower dwelling is a definite improvement on the modern city sprawl. Tall buildings (with the exception of glassed-office buildings and landmarks) are often found in sad scenes.

In recent years, the new mayor of the Colombian capital Bogota, Enrique Penalosa, has cancelled highways projects and poured the money instead into cycle lanes, parks and open spaces for locals – undoing decades of car-centric planning that had made the streets a no-go area for the capital’s children. On the day in February 2000 when Penalosa banned cars from the street for 24 hours, hospital admissions fell by a third, air pollution levels dropped and residents said it made them feel more optimistic about living in the city.

are the technologies we are designing really helping its users to be happy? Take the simple example of a web map. It usually gives us the shortest walking direction to destination. But what if it would give us the small street, full of trees, parallel to the shortest path, which would make us happier? As more and more of us share these city streets, what will keep us happy as they become more crowded?

the share of the world’s population living in cities has surpassed 50%. By 2025, we will see another 1.2 billion city residents. With more and more of us moving to urban centres, quality of life becomes ever-more important.

when parents, grandparents and Little League coaches became core users of Facebook, kids naturally gravitated to new places where they could socialize away from the watchful eye of adults, experts say.

“The worst stuff happens on the anonymous sites because people are either too scared to say something to someone’s face or they want to present someone with public humiliation,” Olivia said.

Numerous psychological studies show conflict is often resolved when people talk face-to-face. When people can see signs of sadness or other emotions, they tend to back down. Facebook said the majority of users who are flagged for abusive or bullying conduct never do it again. On the anonymous sites, there are no such brakes on negative behavior.

Since at least the Middle Ages, philosophers and philologists have dreamed of curing natural languages of their flaws by constructing entirely new idioms according to orderly, logical principles.

What if, they wondered, you could create a universal written language that could be understood by anyone, a set of “real characters,” just as the creation of Arabic numerals had done for counting? “This writing will be a kind of general algebra and calculus of reason, so that, instead of disputing, we can say that ‘we calculate,’ ” Leibniz wrote, in 1679.

nventing new forms of speech is an almost cosmic urge that stems from what the linguist Marina Yaguello, the author of “Lunatic Lovers of Language,” calls “an ambivalent love-hate relationship.” Language creation is pursued by people who are so in love with what language can do that they hate what it doesn’t. “I don’t believe any other fantasy has ever been pursued with so much ardor by the human spirit, apart perhaps from the philosopher’s stone or the proof of the existence of God; or that any other utopia has caused so much ink to flow, apart perhaps from socialism,”

Quijada began wondering, “What if there were one single language that combined the coolest features from all the world’s languages?”

Solresol, the creation of a French musician named Jean-François Sudre, was among the first of these universal languages to gain popular attention. It had only seven syllables: Do, Re, Mi, Fa, So, La, and Si. Words could be sung, or performed on a violin. Or, since the language could also be translated into the seven colors of the rainbow, sentences could be woven into a textile as a stream of colors.

“I had this realization that every individual language does at least one thing better than every other language,” he said. For example, the Australian Aboriginal language Guugu Yimithirr doesn’t use egocentric coördinates like “left,” “right,” “in front of,” or “behind.” Instead, speakers use only the cardinal directions. They don’t have left and right legs but north and south legs, which become east and west legs upon turning ninety degrees

Among the Wakashan Indians of the Pacific Northwest, a grammatically correct sentence can’t be formed without providing what linguists refer to as “evidentiality,” inflecting the verb to indicate whether you are speaking from direct experience, inference, conjecture, or hearsay.

In his “Essay Towards a Real Character, and a Philosophical Language,” from 1668, Wilkins laid out a sprawling taxonomic tree that was intended to represent a rational classification of every concept, thing, and action in the universe. Each branch along the tree corresponded to a letter or a syllable, so that assembling a word was simply a matter of tracing a set of forking limbs

he started scribbling notes on an entirely new grammar that would eventually incorporate not only Wakashan evidentiality and Guugu Yimithirr coördinates but also Niger-Kordofanian aspectual systems, the nominal cases of Basque, the fourth-person referent found in several nearly extinct Native American languages, and a dozen other wild ways of forming sentences.

he discovered “Metaphors We Live By,” a seminal book, published in 1980, by the cognitive linguists George Lakoff and Mark Johnson, which argues that the way we think is structured by conceptual systems that are largely metaphorical in nature. Life is a journey. Time is money. Argument is war. For better or worse, these figures of speech are profoundly embedded in how we think.

I asked him if he could come up with an entirely new concept on the spot, one for which there was no word in any existing language. He thought about it for a moment. “Well, no language, as far as I know, has a single word for that chin-stroking moment you get, often accompanied by a frown on your face, when someone expresses an idea that you’ve never thought of and you have a moment of suddenly seeing possibilities you never saw before.” He paused, as if leafing through a mental dictionary. “In Ithkuil, it’s ašţal.”

Neither Sapir nor Whorf formulated a definitive version of the hypothesis that bears their names, but in general the theory argues that the language we speak actually shapes our experience of reality. Speakers of different languages think differently. Stronger versions of the hypothesis go even further than this, to suggest that language constrains the set of possible thoughts that we can have. In 1955, a sociologist and science-fiction writer named James Cooke Brown decided he would test the Sapir-Whorf hypothesis by creating a “culturally neutral” “model language” that might recondition its speakers’ brains.

most conlangers come to their craft by way of fantasy and science fiction. J. R. R. Tolkien, who called conlanging his “secret vice,” maintained that he created the “Lord of the Rings” trilogy for the primary purpose of giving his invented languages, Quenya, Sindarin, and Khuzdul, a universe in which they could be spoken. And arguably the most commercially successful invented language of all time is Klingon, which has its own translation of “Hamlet” and a dictionary that has sold more than three hundred thousand copies.

He imagined that Ithkuil might be able to do what Lakoff and Johnson said natural languages could not: force its speakers to precisely identify what they mean to say. No hemming, no hawing, no hiding true meaning behind jargon and metaphor. By requiring speakers to carefully consider the meaning of their words, he hoped that his analytical language would force many of the subterranean quirks of human cognition to the surface, and free people from the bugs that infect their thinking.

Brown based the grammar for his ten-thousand-word language, called Loglan, on the rules of formal predicate logic used by analytical philosophers. He hoped that, by training research subjects to speak Loglan, he might turn them into more logical thinkers. If we could change how we think by changing how we speak, then the radical possibility existed of creating a new human condition.

today the stronger versions of the Sapir-Whorf hypothesis have “sunk into . . . disrepute among respectable linguists,” as Guy Deutscher writes, in “Through the Looking Glass: Why the World Looks Different in Other Languages.” But, as Deutscher points out, there is evidence to support the less radical assertion that the particular language we speak influences how we perceive the world. For example, speakers of gendered languages, like Spanish, in which all nouns are either masculine or feminine, actually seem to think about objects differently depending on whether the language treats them as masculine or feminine

The final version of Ithkuil, which Quijada published in 2011, has twenty-two grammatical categories for verbs, compared with the six—tense, aspect, person, number, mood, and voice—that exist in English. Eighteen hundred distinct suffixes further refine a speaker’s intent. Through a process of laborious conjugation that would befuddle even the most competent Latin grammarian, Ithkuil requires a speaker to home in on the exact idea he means to express, and attempts to remove any possibility for vagueness.

Every language has its own phonemic inventory, or library of sounds, from which a speaker can string together words. Consonant-poor Hawaiian has just thirteen phonemes. English has around forty-two, depending on dialect. In order to pack as much meaning as possible into each word, Ithkuil has fifty-eight phonemes. The original version of the language included a repertoire of grunts, wheezes, and hacks that are borrowed from some of the world’s most obscure tongues. One particular hard-to-make clicklike sound, a voiceless uvular ejective affricate, has been found in only a few other languages, including the Caucasian language Ubykh, whose last native speaker died in 1992.

Human interactions are governed by a set of implicit codes that can sometimes seem frustratingly opaque, and whose misreading can quickly put you on the outside looking in. Irony, metaphor, ambiguity: these are the ingenious instruments that allow us to mean more than we say. But in Ithkuil ambiguity is quashed in the interest of making all that is implicit explicit. An ironic statement is tagged with the verbal affix ’kçç. Hyperbolic statements are inflected by the letter ’m.

“I wanted to use Ithkuil to show how you would discuss philosophy and emotional states transparently,” Quijada said. To attempt to translate a thought into Ithkuil requires investigating a spectrum of subtle variations in meaning that are not recorded in any natural language. You cannot express a thought without first considering all the neighboring thoughts that it is not. Though words in Ithkuil may sound like a hacking cough, they have an inherent and unavoidable depth. “It’s the ideal language for political and philosophical debate—any forum where people hide their intent or obfuscate behind language,” Quijada co

In Ithkuil, the difference between glimpsing, glancing, and gawking is the mere flick of a vowel. Each of these distinctions is expressed simply as a conjugation of the root word for vision. Hunched over the dining-room table, Quijada showed me how he would translate “gawk” into Ithkuil. First, though, since words in Ithkuil are assembled from individual atoms of meaning, he had to engage in some introspection about what exactly he meant to say.For fifteen minutes, he flipped backward and forward through his thick spiral-bound manuscript, scratching his head, pondering each of the word’s aspects, as he packed the verb with all of gawking’s many connotations. As he assembled the evolving word from its constituent meanings, he scribbled its pieces on a notepad. He added the “second degree of the affix for expectation of outcome” to suggest an element of surprise that is more than mere unpreparedness but less than outright shock, and the “third degree of the affix for contextual appropriateness” to suggest an element of impropriety that is less than scandalous but more than simply eyebrow-raising. As he rapped his pen against the notepad, he paged through his manuscript in search of the third pattern of the first stem of the root for “shock” to suggest a “non-volitional physiological response,” and then, after several moments of contemplation, he decided that gawking required the use of the “resultative format” to suggest “an event which occurs in conjunction with the conflated sense but is also caused by it.” He eventually emerged with a tiny word that hardly rolled off the tongue: apq’uxasiu. He spoke the first clacking syllable aloud a couple of times before deciding that he had the pronunciation right, and then wrote it down in the script he had invented for printed Ithkuil:

“You can make up words by the millions to describe concepts that have never existed in any language before,” he said.

Many conlanging projects begin with a simple premise that violates the inherited conventions of linguistics in some new way. Aeo uses only vowels. Kēlen has no verbs. Toki Pona, a language inspired by Taoist ideals, was designed to test how simple a language could be. It has just a hundred and twenty-three words and fourteen basic sound units. Brithenig is an answer to the question of what English might have sounded like as a Romance language, if vulgar Latin had taken root on the British Isles. Láadan, a feminist language developed in the early nineteen-eighties, includes words like radíidin, defined as a “non-holiday, a time allegedly a holiday but actually so much a burden because of work and preparations that it is a dreaded occasion; especially when there are too many guests and none of them help.”

“We think that when a person learns Ithkuil his brain works faster,” Vishneva told him, in Russian. She spoke through a translator, as neither she nor Quijada was yet fluent in their shared language. “With Ithkuil, you always have to be reflecting on yourself. Using Ithkuil, we can see things that exist but don’t have names, in the same way that Mendeleyev’s periodic table showed gaps where we knew elements should be that had yet to be discovered.”

Lakoff, who is seventy-one, bearded, and, like Quijada, broadly built, seemed to have read a fair portion of the Ithkuil manuscript and familiarized himself with the language’s nuances.“There are a whole lot of questions I have about this,” he told Quijada, and then explained how he felt Quijada had misread his work on metaphor. “Metaphors don’t just show up in language,” he said. “The metaphor isn’t in the word, it’s in the idea,” and it can’t be wished away with grammar.“For me, as a linguist looking at this, I have to say, ‘O.K., this isn’t going to be used.’ It has an assumption of efficiency that really isn’t efficient, given how the brain works. It misses the metaphor stuff. But the parts that are successful are really nontrivial. This may be an impossible language,” he said. “But if you think of it as a conceptual-art project I think it’s fascinating.”

Pythagoras believed that “all things are number”: things come into existence when mathematical order is imposed on the formless stuff of the universe. He is believed to have come to this idea after discovering the importance of mathematics in music.

Musical order and beauty are similarly the result of order and harmony being carved out of cacophonous noise. Pythagoras also originated the idea of the heavenly ‘music of the spheres’, inaudible to us, made by the movement of the planets around the earth.

In his La Monadologie (Monadology, 1714), Gottfried Leibniz explained our response to art through subconscious perceptions (“les petites sensations”) of “the secret arithmetic” of intervals and other relationships in music and painting.

Immanuel Kant wrote a book on aesthetics, The Critique of Judgment (1790), in which he described aesthetic qualities as those which give us “disinterested pleasure”. They do this through their beauty, which Kant, as a classically-inclined thinker, saw in their harmony of form; or through their sublimity – meaning a perceived grandeur or power that does not threaten us.

Friedrich Schelling was the first of these transcendental idealists, and the first philosopher who thought that instrumental (as distinct from vocal) music was the purest and most disembodied of the arts, and enabled us not only to glimpse the Absolute – a word he coined, although Kant had talked about absolute truth being found in the Ding an Sich [‘the thing-in-itself’] – but during that experience, to see ourselves as an integral part of it. This idea would be taken much further still by:

Other expats find that their alienation – sometimes called reverse culture shock – can take a more serious turn

Ms. Okona stopped leaving the house and cut herself off from friends. Finally, her father asked her if she wanted to see a therapist. When she did, she was diagnosed with “situational depression,” or a depression caused in her case by her inability to adjust to the transition of her new life.

it’s easy for returning expats to feel isolated. “Nobody gets it. It’s like having somebody dying and there’s no funeral and you’re not supposed to talk about it. You feel guilty talking about it.”

The Rev. Ken MacHarg, who served as a pastor in six countries around the world, says that he tells people that moving overseas will “mess you up for the rest of your life. You’re constantly torn between those places, and you’re a changed person.”

Children, who may appear to be excited to return home and reunite with old friends, sometimes hide their identities as Third Culture Kids. Ms. Foley, who had lived for years in France with her family, says that her children were fluent in French. But when one daughter took a French class back in Canada, she spoke French with a strong Anglo accent.

Many repatriated expats find it hard to connect to friends again at home. Ms. Hattaway says that expat life draws people together: “You’re in a circle or tribe with other expats. But back home, you’re only one in a sea of people. Some of them have never left, some don’t have passports. And you look like everyone els

Tina Quick, who lives outside of Boston, says that although she’s been back in the States for 10 years, she still doesn’t have a best friend, someone she could call in an emergency.  She didn’t understand why she never heard from the other soccer parents she met after the season ended

many companies limit the amount of time employees can spend in a particular posting. “They may say you have to go home or go somewhere else. But you might say, I actually like living here,” he says.

Expats need to know that the toughest assignment of all might be coming home. “Send me home?” asks Ms. Pascoe. “It’s easier to go to Bangkok than to repatriate in Vancouver.”

The ban would only prohibit involvement in what the association defines as national security interrogations, which are those conducted by the American military or intelligence agencies, or by contractors or foreign governments outside traditional domestic criminal law enforcement inside the United States.

Psychologists played crucial roles in the post-9/11 harsh interrogation programs created by the C.I.A. and Pentagon, and their involvement helped the Bush administration claim that the abusive interrogation techniques were legal. The involvement of psychologists in the interrogations enabled the Justice Department to issue secret legal opinions arguing that the interrogations were safe because they were being monitored by health professionals, and thus did not constitute torture.

Even before Friday’s vote, the Hoffman report and its unsparing findings of collusion during the Bush administration had already had a dramatic impact on the A.P.A. Four top association officials, including its chief executive and his deputy, have left the organization since the report was released in July.

To create this lexicon, they hired actors to mime the expressions, then asked volunteers to describe their meaning, taking the majority response as the accurate one.

The camera tracks 24 "feature points" on your conversation partner's face, and software developed by Picard analyses their myriad micro-expressions, how often they appear and for how long. It then compares that data with its bank of known expressions (see diagram).

Eventually, she thinks the system could be incorporated into a pair of augmented-reality glasses, which would overlay computer graphics onto the scene in front of the wearer.

In addition to facial expressions, we radiate a panoply of involuntary "honest signals", a term identified by MIT Media Lab researcher Alex Pentland in the early 2000s to describe the social signals that we use to augment our language. They include body language such as gesture mirroring, and cues such as variations in the tone and pitch of the voice. We do respond to these cues, but often not consciously. If we were more aware of them in others and ourselves, then we would have a fuller picture of the social reality around us, and be able to react more deliberately.

Some of our body's responses during a conversation are not designed for broadcast to another person - but it's possible to monitor those too. Your temperature and skin conductance can also reveal secrets about your emotional state, and Picard can tap them with a glove-like device called the Q Sensor. In response to stresses, good or bad, our skin becomes clammy, increasing its conductance, and the Q Sensor picks this up.

Physiological responses can now even be tracked remotely, in principle without your consent. Last year, Picard and one of her graduate students showed that it was possible to measure heart rate without any surface contact with the body. They used software linked to an ordinary webcam to read information about heart rate, blood pressure and skin temperature based on, among other things, colour changes in the subject's face

In Rio de Janeiro and Sao Paolo, police officers can decide whether someone is a criminal just by looking at them. Their glasses scan the features of a face, and match them against a database of criminal mugshots. A red light blinks if there's a match.
