Mimick other people's body language to gain their sympathy


In a recent experiment, Rick van Baaren, a psychologist at Nijmegen University in the Netherlands, had student participants go to a lab and give their opinions about a series of advertisements. A member of his research team mimicked half the participants while they spoke, roughly mirroring the posture and the position of their arms and legs, taking care not to be too obvious.

Minutes later, the experimenter dropped six pens on the floor, making it look like an accident.

In several versions of this simple sequence, participants who had been mimicked were two to three times as likely to pick up the pens as those who had not.

Mind
You Remind Me of Me
By BENEDICT CAREY

Artful persuasion depends on eye contact, but not just any kind. If one person prefers brief glances and the other is busy staring deeply, then it may not matter how good the jokes are or how much they both loved “Juno.” Rhythm counts.

Voice cadence does, too. People who speak in loud, animated bursts tend to feed off others who do the same, just as those who are lower key tend to relax in a cool stream of measured tones.

“Myself, I’m very conscious of people’s body position,” said Ray Allieri of Wellesley, Mass., a former telecommunications executive with 20 years in marketing and sales. “If they’re leaning back in their chair, I do that, and if they’re forward on their elbows, I tend to move forward,”

Psychologists have been studying the art of persuasion for nearly a century, analyzing activities like political propaganda, television campaigns and door-to-door sales. Many factors influence people’s susceptibility to an appeal, studies suggest, including their perception of how exclusive an opportunity is and whether their neighbors are buying it.

Most people are also strongly sensitive to rapport, to charm, to the social music in the person making the pitch. In recent years, researchers have begun to decode the unspoken, subtle elements that come into play when people click.

They have found that immediate social bonding between strangers is highly dependent on mimicry, a synchronized and usually unconscious give and take of words and gestures that creates a current of good will between two people.

By understanding exactly how this process works, researchers say, people can better catch themselves when falling for an artful pitch, and even sharpen their own social skills in ways they may not have tried before.

“Really good salespeople, and for that matter good con artists, have known about these skills and used them forever,” Jeremy Bailenson, a psychologist at Stanford, said. “All we’re doing now is measuring and describing more precisely what it is they’re doing, whether consciously or not.”

Imitation is one of the most common and recognizable behaviors in the animal kingdom. Just as baby chimps learn to climb by aping their elders, so infants pick up words and gestures by copying parents. They sense and mimic peers’ behavior from early on, too, looking up at the ceiling if others around them do so or mirroring others’ cringes of fear and anxiety.

Such behavioral contagion probably evolved early for survival, some scientists argue. It is what scatters a flock well before most members see a lunging predator.

Yet by drawing on apparently similar skills, even in seemingly trivial ways, people can prompt almost instantaneous cooperation from complete strangers.

In a recent experiment, Rick van Baaren, a psychologist at Nijmegen University in the Netherlands, had student participants go to a lab and give their opinions about a series of advertisements. A member of his research team mimicked half the participants while they spoke, roughly mirroring the posture and the position of their arms and legs, taking care not to be too obvious.

Minutes later, the experimenter dropped six pens on the floor, making it look like an accident.

In several versions of this simple sequence, participants who had been mimicked were two to three times as likely to pick up the pens as those who had not.

The mimicry had not only increased good will toward the researcher within minutes, the study concluded, but it also prompted “an increased pro-social orientation in general.”

That orientation applies to far more than dropped pens. In a study due out in the spring, Robin Tanner and Tanya Chartrand, psychologists at Duke, led a research team that tested how being mimicked might affect the behavior of a potential client or investor.

The team had 37 Duke students try out what was described as a new sports drink, Vigor, and answer a few questions about it. The interviewer mimicked about half the participants using a technique Dr. Chartrand had developed in earlier studies.

The technique involved mirroring a person’s posture and movements, with a one- to two-second delay. If he crosses his legs, then wait two seconds and do the same, with opposite legs. If she touches her face, wait a beat or two and do that. If he drums his fingers or taps a toe, wait again and do something similar.

The idea is to be a mirror but a slow, imperfect one. Follow too closely, and most people catch it — and the game is over.

In the study, the researchers set up the interviews so each student’s experience was virtually identical, except for the mimicking.

None of the copied participants picked up on the mimicry. But by the end of the short interview, they were significantly more likely than the others to consume the new drink, to say they would buy it and to predict its success in the market.

In a similar experiment, the psychologists found that this was especially true if the participants knew that the interviewer, the mimic, had a stake in the product’s success.

“This is somewhat counterintuitive,” Dr. Chartrand said in an interview. “Normally, you’d expect when people realize that someone was invested in a product and trying to sell it to them, their reaction would be attenuated. They’d be less enthusiastic.

“But we found that people who were mimicked actually felt more strongly about the product when they knew the other person was invested in it.”

Any amiable conversation provides ample evidence of this subconscious social waltz. Smiles are contagious. So is nodding, in an amiable conversation.

Accents converge quickly and automatically. A country chime or an Irish whistle can seemingly infect the voice of a New Yorker in a 10-minute phone call.

“I especially find myself falling into a Southern accent, which is crazy,” Mr. Allieri, the telecom executive, said. “I’m from Boston.

“But I think what good salespeople really do is pick up on physical cues and respond to them without thinking much about it.”

It is one thing to move like a naturally synchronized swimmer through the pools of everyday conversation without thinking, however. It is another to deliberately employ mimicry to persuade or seduce.

Dr. Bailenson, the Stanford psychologist, has been testing the effects of different forms of mimicry by programming a computer-generated figure, an avatar, to mirror the movements and gestures of people in a study.

He has found that his subjects pick up the mimicry when it is immediate and precise. If the avatar is slightly out of sync, however — waits four seconds, for instance — then the mimicking goes unnoticed, and the usual rules apply. The virtual creating comes across as warm and convincing, as if controlled by another human.

“The point is it’s a delicate balance to get it right, and I suspect that people who are good at this know how to do it intuitively,” Dr. Bailenson said.

Or they have developed ways to engage their skills indirectly.

Veldon Smith, a musician and legendary salesman living in Centennial, Colo., who spent 30 years in the automobile parts business before retiring a few years ago, said:

“One thing I always did, I learned as much as possible about a client before I visited, what their problem was, what they were worried about. Then I would go in with a story about myself being in the same predicament.

“So when I walked in, I was in exactly the same frame of mind as the customer. I was immediately on the same wavelength. Everything else kind of flowed out of that.”

One reason subtle mimicry is so instantly beguiling may be that it draws on and, perhaps, activates brain circuits involved in feelings of empathy.

In several studies, Jean Decety, a neuroscientist at the University of Chicago, has shown that some of the same brain regions that are active when a person feels pain also flare up when that person imagines someone else like a loved one feeling the same sting or ache.

A similar process almost certainly occurs when a person takes pleasure in the good fortune of a friend or the apparent enjoyment of a conversation partner, Dr. Decety said.

“When you’re being mimicked in a good way, it communicates a kind of pleasure, a social high you’re getting from the other person, and I suspect it activates the areas of the brain involved in sensing reward,” he said.

Social mimicry can and does go wrong. At its malicious extreme, it curdles into mockery, which is why people often recoil when they catch of whiff of mimicry, ending any chance of a social bond. Preliminary studies suggest that the rules change if there is a wide cultural gap between two people. For almost everyone else, however, subtle mimicry comes across as a form of flattery, the physical dance of charm itself. And if that kind of flattery doesn’t close a deal, it may just be that the customer isn’t buying.

Everyone has the right to be charmed but not seduced.

building the new U.S. Embassy in Baghdad


The compound will comprise 21 buildings on 104 acres (42 ha), making it the largest and most expensive U.S. embassy in the world.

The complex is said to be heavily fortified, even by the standards of the Green Zone. The details are largely secret, but it is likely to include a significant U.S. Marine Security Guard detachment. Fortifications are to include deep security perimeters, buildings reinforced beyond the standard, and five highly guarded entrances.

Subliminal smells can have powerful effects

Subliminal smells can have powerful effects

IN A world where sight and sound seem to reign supreme, all it takes is a cursory glance at the size of the perfume industry to realise that smell matters quite a lot, too. Odours are known to regulate moods, thoughts and even dating decisions, which is why any serious romantic will throw on the eau de toilette before going out for a night on the town. Yet in all these cases, those affected are aware of what they are smelling. Unlike the media of sight and sound, in which subliminal messages have been studied carefully, the potential power of subliminal smells has been neglected.

Wen Li and her colleagues at Northwestern University in Chicago are now changing that. In particular, they are investigating smells so faint that people say they cannot detect them. The idea is to see whether such smells can nevertheless change the way that people behave towards others.

Dr Li's experiment, the results of which have just been published in Psychological Science, employed 31 volunteers. These people were exposed to three different odours at low concentration. One was the fresh lemon scent of citral. The second was the neutral ethereal perfume of anisole. The third was the foul sweaty smell of valeric acid. And the concentrations really were low. In the case of valeric acid, for example, that concentration was seven parts per trillion—a level only just detectable by bloodhounds. As a control, Dr Li used a mineral oil that has no detectable smell at any concentration.

The participants were asked to sniff a jar containing either one of the three odours or the scentless oil, and then press a button to indicate whether they thought the jar smelled of anything. Immediately after that, a picture of a face would appear on a screen in front of them for just over a second. Each participant was asked to rate the face's “likeability”.

Dr Li found that the odours helped shape people's judgments about the faces when their responses indicated that they had not smelled anything. When someone had been exposed to valeric acid, for example, he tended to react negatively to a face. Exposure to citral, by contrast, made that face seem, on average, more friendly. (Obviously, the same face was not shown to any given participant more than once.) Even more intriguing, however, was that when participants did consciously perceive a smell, its effect on face-perception disappeared.

What is going on is unclear. If smells can carry useful information about personality (which is possible), then the effect would be expected to be the same whether or not the chemical in question is detected subliminally. If they do not carry such information, then it is hard to see what use the subliminal reaction is. Nevertheless, it is there.

The findings do, however, demonstrate what might be a powerful method of manipulation. Indeed, Dr Li considers the potential uses to be vast. Business meetings might be made more pleasant by releasing appropriate fragrances into the air in unsmellable amounts. Conversely, fights might be started by putting people in the presence of a faint foul odour. Advertising hoardings might benefit from a little olfactory tweaking and cinema audiences could be reduced to floods of tears at the appropriate moment. The sweet smell of success might, in other words, actually be undetectable.

The sex of a child may depend on how stressed its mother is

The sex of a child may depend on how stressed its mother is

A BOY or a girl? That is usually the first question asked when a woman gives birth. Remarkably, the answer varies with where the mother lives. In rich countries the chances of its being a boy are about 5% higher than in poor ones. Equally remarkably, that figure has been falling recently. Several theories have been put forward to explain these observations. Some argue that smoking plays a role, others that diet may be important. Neither of these ideas has been supported by evidence from large studies. But new research points to a different factor: stress.

Strange as it might seem, the terrorist attacks of September 11th 2001 shed light on the enigma. Studies noting the sex of babies conceived in New York during the week of the attacks found a drop in the ratio of males to females. That is consistent with earlier studies, which revealed a similar shift in women who became pregnant during floods and earthquakes and in time of war. Moreover, a study carried out eight years ago by researchers at the University of Aarhus, in Denmark, revealed that women who suffered the death of a child or spouse from some catastrophic illness (such as a heart attack) around the time they conceived were much more likely to give birth to girls than to boys.

Taken together, these results suggest that acute stress to a woman at the time of conception shifts the sex ratio towards girls. However, Carsten Obel, a researcher at Aarhus who was not involved in the earlier study, wondered if the same might be true of chronic stress too. In a paper just published in Human Development, he shows that it is.

Dr Obel used a set of data collected between 1989 and 1992. During that period 8,719 expectant mothers were asked to fill in questionnaires that inquired, among other things, about their level of stress. Dr Obel found that the more stressed a mother had been, the less chance she had of having given birth to a boy. Only 47% of children born to women in the top quartile of stress were males. That compared with 52% for women in the bottom quartile.

Dr Obel suspects the immediate cause is that male pregnancies are more likely to miscarry in response to stress than female pregnancies are, especially during the first three months. However, that is difficult to prove. More intriguing, though, is the ultimate cause, for he thinks it might be adaptive, rather than pathological.

That is because the chances are that a daughter who reaches adulthood will find a mate and thus produce grandchildren. A son is a different matter. Healthy, strapping sons are likely to produce lots of grandchildren, by several women—or would have done in the hunter-gatherer societies in which most human evolution took place. Weak ones would be marginalised and maybe even killed in the cut and thrust of male competition. If a mother's stress adversely affects the development of her fetus (as it is likely to do) then selectively aborting boys, rather than wasting time and resources on bringing them to term, would make evolutionary sense.

That, in turn, would explain why women in rich countries, who are less likely to suffer from hunger and disease, are more likely to give birth to sons. That this likelihood is, nevertheless, falling suggests that rich women's lives may be more stressful than they used to be.

The End of the World by Archibald MacLeish

The End of the World

Quite unexpectedly, as Vasserot
The armless ambidextrian was lighting
A match between his great and second toe,
And Ralph the lion was engaged in biting
The neck of Madame Sossman while the drum
Pointed, and Teeny was about to cough
In waltz-time swinging Jocko by the thumb
Quite unexpectedly the top blew off:

And there, there overhead, there, there hung over
Those thousands of white faces, those dazed eyes,
There in the starless dark, the poise, the hover,
There with vast wings across the cancelled skies,
There in the sudden blackness the black pall
Of nothing, nothing, nothing -- nothing at all.

-- Archibald MacLeish

Coins cost more to make than face value

http://www.usatoday.com/money/2006-05-09-penny-usat_x.htm

EXCERPTS from article written in 2006:

"The Mint estimates it will cost 1.23 cents per penny and 5.73 cents per nickel this fiscal year, which ends Sept. 30. The cost of producing a penny has risen 27% in the last year, while nickel manufacturing costs have risen 19%."

"The estimates take into account rising metals prices as well as processing, labor and transportation costs. Based on current metals prices, the value of the metal in a nickel alone is a little more than 5 cents. The metal in a penny, however, is still worth less than a penny."

"The Federal Reserve, which distributes money to banks, pays face value for coins. If a coin costs less to manufacture than the face value, the Mint makes a profit. Last year, the Mint's coin-making profit was $730 million. Mint officials estimate the added penny and nickel expenses will reduce the Mint's profit this year by $45 million."

PRKA (People Reluctant To Kill for an Abstraction)

Manifesto
A press release from PRKA.
By George Saunders
Posted Thursday, Aug. 26, 2004, at 3:59 PM ET
--------------------------------------------------------------------------------


Last Thursday, my organization, People Reluctant To Kill for an Abstraction, orchestrated an overwhelming show of force around the globe.

At precisely 9 in the morning, working with focus and stealth, our entire membership succeeded in simultaneously beheading no one. At 10, Phase II began, during which our entire membership did not force a single man to suck another man's penis. Also, none of us blew himself/herself up in a crowded public place. No civilians were literally turned inside out via our powerful explosives. In addition, at 11, in Phase III, zero (0) planes were flown into buildings.

During Phase IV, just after lunch, we were able to avoid bulldozing a single home. Furthermore, we set, on roads in every city, in every nation in the world, a total of zero (0) roadside bombs which, not being there, did not subsequently explode, killing/maiming a total of nobody. No bombs were dropped, during the lazy afternoon hours, on crowded civilian neighborhoods, from which, it was observed, no post-bomb momentary silences were then heard. These silences were, in all cases, followed by no unimaginable, grief-stricken bellows of rage, and/or frantic imprecations to a deity. No sleeping baby was awakened from an afternoon nap by the sudden collapse and/or bursting into flame of his/her domicile during Phase IV.

In the late afternoon (Phase V), our membership focused on using zero (0) trained dogs to bite/terrorize naked prisoners. In addition, no stun guns, rubber batons, rubber bullets, tear gas, or bullets were used, by our membership, on any individual, anywhere in the world. No one was forced to don a hood. No teeth were pulled in darkened rooms. No drills were used on human flesh, nor were whips or flames. No one was reduced to hysterical tears via a series of blows to the head or body, by us. Our membership, while casting no racial or ethnic aspersions, skillfully continued not to rape, gang-rape, or sexually assault a single person. On the contrary, during this late-afternoon phase, many of our membership flirted happily and even consoled, in a nonsexual way, individuals to whom they were attracted, putting aside their sexual feelings out of a sudden welling of empathy.

As night fell, our membership harbored no secret feelings of rage or, if they did, meditated, or discussed these feelings with a friend until such time as the feelings abated, or were understood to be symptomatic of some deeper sadness.

It should be noted that, in addition to the above-listed and planned activities completed by our members, a number of unplanned activities were completed by part-time members, or even nonmembers.

In London, a bitter homophobic grandfather whose grocery bag broke open gave a loaf of very nice bread to a balding gay man who stopped to help him. A stooped toothless woman in Tokyo pounded her head with her hands, tired beyond belief of her lifelong feelings of anger and negativity, and silently prayed that her heart would somehow be opened before it was too late. In Syracuse, New York, holding the broken body of his kitten, a man felt a sudden kinship for all small things.

Even declared nonmembers, it would appear, responded to our efforts. In Chitral, Pakistan, for example, a recent al-Qaida recruit remembered the way an elderly American tourist once made an encouraging remark about his English, and how, as she made the remark, she touched his arm, like a mother. In Gaza, an Israeli soldier and a young Palestinian, just before averting their eyes and muttering insults in their respective languages, exchanged a brief look of mutual shame.

Who are we? A word about our membership.

Since the world began, we have gone about our work quietly, resisting the urge to generalize, valuing the individual over the group, the actual over the conceptual, the inherent sweetness of the present moment over the theoretically peaceful future to be obtained via murder. Many of us have trouble sleeping and lie awake at night, worrying about something catastrophic befalling someone we love. We rise in the morning with no plans to convert anyone via beating, humiliation, or invasion. To tell the truth, we are tired. We work. We would just like some peace and quiet. When wrong, we think about it awhile, then apologize. We stand under awnings during urban thunderstorms, moved to thoughtfulness by the troubled, umbrella-tinged faces rushing by. In moments of crisis, we pat one another awkwardly on the back, mumbling shy truisms. Rushing to an appointment, remembering a friend who has passed away, our eyes well with tears and we think: Well, my God, he could be a pain, but still I'm lucky to have known him.

This is PRKA. To those who would oppose us, I would simply say: We are many. We are worldwide. We, in fact, outnumber you. Though you are louder, though you create a momentary ripple on the water of life, we will endure, and prevail.

Join us.

Resistance is futile.
