The conspiracy mindset

history, politics, science / /

From Alex Koppelman’s “Why the stories about Obama’s birth certificate will never die” (Salon: 5 December 2008):

But according to several experts in conspiracy theories, and in the psychology of people who believe in conspiracy theories, there’s little chance those people who think Obama is barred from the presidency will ever be convinced otherwise. “There’s no amount of evidence or data that will change somebody’s mind,” says Michael Shermer, who is the publisher of Skeptic magazine and a columnist for Scientific American, and who holds an undergraduate and a master’s degree in psychology. “The more data you present a person, the more they doubt it … Once you’re committed, especially behaviorally committed or financially committed, the more impossible it becomes to change your mind.”

Any inconvenient facts are irrelevant. People who believe in a conspiracy theory “develop a selective perception, their mind refuses to accept contrary evidence,” Chip Berlet, a senior analyst with Political Research Associates who studies such theories, says. “As soon as you criticize a conspiracy theory, you become part of the conspiracy.”

Evan Harrington, a social psychologist who is an associate professor at the Chicago School of Professional Psychology, agrees. “One of the tendencies of the conspiracy notion, the whole appeal, is that a lot of the information the believer has is secret or special,” Harrington says. “The real evidence is out there, [and] you can give them all this evidence, but they’ll have convenient ways to discredit [it].”

Whatever can’t be ignored can be twisted to fit into the narrative; every new disclosure of something that should, by rights, end the controversy only opens up new questions, identifies new plotters.

How the fundamentalist thinks

From ScienceDaily’s “Brain Differences Found Between Believers In God And Non-believers” (5 March 2009):

In two studies led by Assistant Psychology Professor Michael Inzlicht, participants performed a Stroop task – a well-known test of cognitive control – while hooked up to electrodes that measured their brain activity.

Compared to non-believers, the religious participants showed significantly less activity in the anterior cingulate cortex (ACC), a portion of the brain that helps modify behavior by signaling when attention and control are needed, usually as a result of some anxiety-producing event like making a mistake. The stronger their religious zeal and the more they believed in God, the less their ACC fired in response to their own errors, and the fewer errors they made.

“You could think of this part of the brain like a cortical alarm bell that rings when an individual has just made a mistake or experiences uncertainty,” says lead author Inzlicht, who teaches and conducts research at the University of Toronto Scarborough. “We found that religious people or even people who simply believe in the existence of God show significantly less brain activity in relation to their own errors. They’re much less anxious and feel less stressed when they have made an error.”

…

“Obviously, anxiety can be negative because if you have too much, you’re paralyzed with fear,” [Inzlicht] says. “However, it also serves a very useful function in that it alerts us when we’re making mistakes. If you don’t experience anxiety when you make an error, what impetus do you have to change or improve your behaviour so you don’t make the same mistakes again and again?”

Why cons work on us

business, law, security / /

From Damien Carrick’s interview with Nicholas Johnson, “The psychology of conmen” (The Law Report: 30 September 2008):

Nicholas Johnson: I think what I love most about con artists and the world of scammers is that they’re criminals who manage to get their victims to hand over their possessions freely. Most thieves and robbers and the like, tend to use force, or deception, in order for them to take things, whereas a con artist manages to get their victim to freely give up their stuff.

…

The main thing that really makes people susceptible to con artists is the idea that we’re going to get something for nothing. So it really buys into our greed; it buys into sometimes our lust, and at the same time, sometimes even our sense that we’re going to do something good, so we’re going to get a great feeling from helping someone out, we’re going to make some money, we’re going to meet a beautiful girl—it really ties into our basest desires, and that’s what the con artist relies on.

…

Most con artists rely on this idea that the victim is in control. The victim is the one who is controlling the situation. So a great example of that is the classic Nigerian email scam, the person who writes to you and says, ‘I’ve got this money that I need to get out of the country, and I need your help.’ So you’re in control, you can help them, you can do a good deed, you can make some money, you’ve got this fantastic opportunity, and the con artist needs your help. It’s not the con artist doing you a favour. So really, you feel like you’re the one who’s controlling the situation when really it’s the con artist who knows the real deal.

…

I think for a lot of con artists they’re very proud of their work, and they like people to know exactly what they’ve gotten away with.

…

… for many of [the conmen], they really feel like even if they get caught, or even if they don’t get away with it, they feel like they’re giving their victim a good story, you know, something to dine out over, something to discuss down at the pub. They think that’s OK, you can scam somebody out of a couple of hundred bucks, because they’re getting a good story in return.

…

My all-time favourite one only makes the con artist a few dollars every time he does it, but I absolutely love it. These guys used to go door-to-door in the 1970s selling lightbulbs and they would offer to replace every single lightbulb in your house, so all your old lightbulbs would be replaced with a brand new lightbulb, and it would cost you, say $5, so a fraction of the cost of what new lightbulbs would cost. So the man comes in, he replaces each lightbulb, every single one in the house, and does it, you can check, and they all work, and then he takes all the lightbulbs that he’s just taken from the person’s house, goes next door and then sells them the same lightbulbs again. So it’s really just moving lightbulbs from one house to another and charging people a fee to do it.

But there’s all sorts of those homemaker scams, people offering to seal your roof so they say, ‘We’ll put a fresh coat of tar on your roof’, or ‘We’ll re-seal your driveway’. In actual fact all they do is get old black sump oil and smooth it over the roof or smooth it over the driveway. You come home and it looks like wet tar, and so ‘Don’t step on it for 24 hours’, and of course 24 hours later they’re long gone with the money, and you’re left with a sticky, smelly driveway.

The color of the TV you watch determines the color of your dreams

cool stuff, science / /

From Richard Alleyne’s “Black and white TV generation have monochrome dreams” (The Telegraph: 17 October 2008):

New research suggests that the type of television you watched as a child has a profound effect on the colour of your dreams.

While almost all under 25s dream in colour, thousands of over 55s, all of whom were brought up with black and white sets, often dream in monchrome – even now.

…

Research from 1915 through to the 1950s suggested that the vast majority of dreams are in black and white but the tide turned in the sixties, and later results suggested that up to 83 per cent of dreams contain some colour.

Since this period also marked the transition between black-and-white film and TV and widespread Technicolor, an obvious explanation was that the media had been priming the subjects’ dreams.

Chemically remove bad memories

education, politics, science, tech in changing society, technology / /

From Nicholas Carr’s “Remembering to forget” (Rough Type: 22 October 2008):

Slowly but surely, scientists are getting closer to developing a drug that will allow people to eliminate unpleasant memories. The new issue of Neuron features a report from a group of Chinese scientists who were able to use a chemical – the protein alpha-CaM kinase II – to successfully erase memories from the minds of mice. The memory losses, report the authors, are “not caused by disrupting the retrieval access to the stored information but are, rather, due to the active erasure of the stored memories.” The erasure, moreover, “is highly restricted to the memory being retrieved while leaving other memories intact. Therefore, our study reveals a molecular genetic paradigm through which a given memory, such as new or old fear memory, can be rapidly and specifically erased in a controlled and inducible manner in the brain.”

…

One can think of a whole range of applications, from the therapeutic to the cosmetic to the political.

Hallucinating the presence of the dead

religion, science / /

From Vaughan Bell’s “Ghost Stories: Visits from the Deceased” (Scientific American: 2 December 2008):

The dead stay with us, that much is clear. They remain in our hearts and minds, of course, but for many people they also linger in our senses—as sights, sounds, smells, touches or presences. Grief hallucinations are a normal reaction to bereavement but are rarely discussed, because people fear they might be considered insane or mentally destabilised by their loss. As a society we tend to associate hallucinations with things like drugs and mental illness, but we now know that hallucinations are common in sober healthy people and that they are more likely during times of stress.

Mourning seems to be a time when hallucinations are particularly common, to the point where feeling the presence of the deceased is the norm rather than the exception. One study, by the researcher Agneta Grimby at the University of Goteborg, found that over 80 percent of elderly people experience hallucinations associated with their dead partner one month after bereavement, as if their perception had yet to catch up with the knowledge of their beloved’s passing. As a marker of how vivid such visions can seem, almost a third of the people reported that they spoke in response to their experiences. In other words, these weren’t just peripheral illusions: they could evoke the very essence of the deceased.

Occasionally, these hallucinations are heart-rending. A 2002 case report by German researchers described how a middle aged woman, grieving her daughter’s death from a heroin overdose, regularly saw the young girl and sometimes heard her say “Mamma, Mamma!” and “It’s so cold.” Thankfully, these distressing experiences tend to be rare, and most people who experience hallucinations during bereavement find them comforting, as if they were re-connecting with something of the positive from the person’s life. Perhaps this reconnecting is reflected in the fact that the intensity of grief has been found to predict the number of pleasant hallucinations, as has the happiness of the marriage to the person who passed away.

There are hints that the type of grief hallucinations might also differ across cultures. Anthropologists have told us a great deal about how the ceremonies, beliefs and the social rituals of death differ greatly across the world, but we have few clues about how these different approaches affect how people experience the dead after they have gone.

But we’ve always done it this way …

business, politics / /

From James Bennett’s “Let’s talk about Python 3.0” (The B-List: 5 December 2008):

There’s an old joke, so old that I don’t even know for certain where it originated, that’s often used to explain why big corporations do things the way they do. It involves some monkeys, a cage, a banana and a fire hose.

You build a nice big room-sized cage, and in one end of it you put five monkeys. In the other end you put the banana. Then you stand by with the fire hose. Sooner or later one of the monkeys is going to go after the banana, and when it does you turn on the fire hose and spray the other monkeys with it. Replace the banana if needed, then repeat the process. Monkeys are pretty smart, so they’ll figure this out pretty quickly: “If anybody goes for the banana, the rest of us get the hose.” Soon they’ll attack any member of their group who tries to go to the banana.

Once this happens, you take one monkey out of the cage and bring in a new one. The new monkey will come in, try to make friends, then probably go for the banana. And the other monkeys, knowing what this means, will attack him to stop you from using the hose on them. Eventually the new monkey will get the message, and will even start joining in on the attack if somebody else goes for the banana. Once this happens, take another of the original monkeys out of the cage and bring in another new monkey.

After repeating this a few times, there will come a moment when none of the monkeys in the cage have ever been sprayed by the fire hose; in fact, they’ll never even have seen the hose. But they’ll attack any monkey who goes to get the banana. If the monkeys could speak English, and if you could ask them why they attack anyone who goes for the banana, their answer would almost certainly be: “Well, I don’t really know, but that’s how we’ve always done things around here.”

This is a startlingly good analogy for the way lots of corporations do things: once a particular process is entrenched (and especially after a couple rounds of employee turnover), there’s nobody left who remembers why the company does things this way. There’s nobody who stops to think about whether this is still a good way to do things, or whether it was even a good idea way back at the beginning. The process continues through nothing more than inertia, and anyone who suggests a change is likely to end up viciously attacked by monkeys.

But this is also a really good analogy for the way a lot of software works: a function or a class or a library was written, once upon a time, and maybe at the time it was a good idea. Maybe now it’s not such a good idea, and actually causes more problems than it solves, but hey, that’s the way we’ve always done things around here, and who are you to suggest a change? Should I go get the fire hose?

But we’ve always done it this way … Read More »

A Russian man with perfect memory

history, science / /

From Jonah Lehrer’s “Hell is a Perfect Memory” (The Frontal Cortex: 2 December 2008):

This isn’t the first case report of a person with perfect memory. In the masterful The Mind of A Mnemonist, the Soviet neurologist A.R. Luria documented the story of a Russian newspaper reporter, D.C. Shereshevskii, who was incapable of forgetting. For example, D.C. would be bound by his brain to memorize the entire Divine Comedy of Dante after a single reading. Audiences would scream out random numbers 100 digits long and he would effortlessly recount them. The only requirement of this man’s insatiable memory was that he be given 3 or 4 seconds to visualize each item during the learning process. These images came to D.C. automatically.

Eventually, D.C.’s memory overwhelmed him. He. struggled with mental tasks normal people find easy. When he read a novel, he would instantly memorize every word by heart, but miss the entire plot. Metaphors and poetry – though they clung to his brain like Velcro – were incomprehensible. He couldn’t even use the phone because he found it hard to recognize a person’s voice “when it changes its intonation…and it does that 20 or 30 times a day.”

A woman who never forgets anything

history, science / /

From Samiha Shafy’s “An Infinite Loop in the Brain” (Der Spiegel: 21 November 2008):

Price can rattle off, without hesitation, what she saw and heard on almost any given date. She remembers many early childhood experiences and most of the days between the ages of 9 and 15. After that, there are virtually no gaps in her memory. “Starting on Feb. 5, 1980, I remember everything. That was a Tuesday.”

…

“People say to me: Oh, how fascinating, it must be a treat to have a perfect memory,” she says. Her lips twist into a thin smile. “But it’s also agonizing.”

In addition to good memories, every angry word, every mistake, every disappointment, every shock and every moment of pain goes unforgotten. Time heals no wounds for Price. “I don’t look back at the past with any distance. It’s more like experiencing everything over and over again, and those memories trigger exactly the same emotions in me. It’s like an endless, chaotic film that can completely overpower me. And there’s no stop button.”

She’s constantly bombarded with fragments of memories, exposed to an automatic and uncontrollable process that behaves like an infinite loop in a computer. Sometimes there are external triggers, like a certain smell, song or word. But often her memories return by themselves. Beautiful, horrific, important or banal scenes rush across her wildly chaotic “internal monitor,” sometimes displacing the present. “All of this is incredibly exhausting,” says Price.

…

The scientists were able to verify her autobiographical data because she has meticulously kept a diary since the age of 10. She has filled more than 50,000 pages with tiny writing, documenting every occurrence, no matter how insignificant. Writing things down helps Price organize the thoughts and images shimmering in her head.

In fact, she feels a strong need to document her life. This includes hoarding every possible memento from childhood, including dolls, stuffed animals, cassette tapes, books, a drawer from dresser she had when she was five. “I have to be able to touch my memories,” Price explains.

[James McGaugh, founder of the Center for the Neurobiology of Learning and Memory at the University of California in Irvine,] and his colleagues concluded that Price’s episodic memory, her recollection of personal experiences and the emotions associated with them, is virtually perfect. A case like this has never been described in the history of memory research, according to McGaugh. He explains that Price differs substantially from other people with special powers of recall, such as autistic savants, because she uses no strategies to help her remember and even does a surprisingly poor job on some memory tests.

It’s difficult for her to memorize poems or series of numbers — which helps explain why she never stood out in school. Her semantic memory, the ability to remember facts not directly related to everyday life, is only average.

Two years ago, the scientists published their first conclusions in a professional journal without revealing the identity of their subject. Since then, more than 200 people have contacted McGaugh, all claiming to have an equally perfect episodic memory. Most of them were exposed as fakes. Three did appear to have similarly astonishing abilities. “Their personalities are very different. The others are not as anxious as Jill. But they achieve comparable results in the tests,” McGaugh reports.

The subjects do have certain compulsive traits in common, says McGaugh, especially compulsive hoarding. The three others are left-handed, and Price also showed a tendency toward left-handedness in tests.

…

In neurobiological terms, a memory is a stored pattern of links between nerve cells in the brain. It is created when synapses in a network of neurons are activated for a short time. The more often the memory is recalled afterwards, the more likely it is that permanent links develop between the nerve cells — and the pattern will be stored as a long-term memory. In theory there are so many possible links that an almost unlimited number of memories can be permanently stored.

So why don’t all people have the same powers of recollection as Jill Price? “If we could remember everything equally well, the brain would be hopelessly overburdened and would operate more slowly,” says McGaugh. He says forgetting is a necessary condition of having a viable memory — except in the case of Price and the other three memory superstars.

Denver International Airport, home to alien reptilians enslaving children in deep dungeons

1 Comment / art, history, politics, religion, security, weird / /

From Jared Jacang Maher’s “DIA Conspiracies Take Off” (Denver Westword News: 30 August 2007):

Chris from Indianapolis has heard that the tunnels below DIA [Denver International Airport] were constructed as a kind of Noah’s Ark so that five million people could escape the coming earth change; shaken and earnest, he asks how someone might go about getting on the list.

…

Today, dozens of websites are devoted to the “Denver Airport Conspiracy,” and theorists have even nicknamed the place “Area 52.” Wikipedia presents DIA as a primary example of New World Order symbolism, above the entry about the eyeball/pyramid insignia on the one-dollar bill. And over the past two years, DIA has been the subject of books, articles, documentaries, radio interviews and countless YouTube and forum board postings, all attempting to unlock its mysteries. While the most extreme claim maintains that a massive underground facility exists below the airport where an alien race of reptilian humanoids feeds on missing children while awaiting the date of government-sponsored rapture, all of the assorted theories share a common thread: The key to decoding the truth about DIA and the sinister forces that control our reality is contained within the two Tanguma murals, “In Peace and Harmony With Nature” and “The Children of the World Dream of Peace.”

…

And not all these theorists are Unabomber-like crackpots uploading their hallucinations from basement lairs. Former BBC media personality David Icke, for example, has written twenty books in his quest to prove that the world is controlled by an elite group of reptilian aliens known as the Babylonian Brotherhood, whose ranks include George W. Bush, Queen Elizabeth II, the Jews and Kris Kristofferson. In various writings, lectures and interviews, he has long argued that DIA is one of many home bases for the otherworldly creatures, a fact revealed in the lizard/alien-faced military figure shown in Tanguma’s murals.

“Denver is scheduled to be the Western headquarters of the US New World Order during martial law take over,” Icke wrote in his 1999 book, The Biggest Secret. “Other contacts who have been underground at the Denver Airport claim that there are large numbers of human slaves, many of them children, working there under the control of the reptilians.”

On the other end of the conspiracy spectrum is anti-vaccination activist Dr. Len Horowitz, who believes that global viruses such as AIDS, Ebola, West Nile, tuberculosis and SARS are actually population-control plots engineered by the government. The former dentist from Florida does not speak about 2012 or reptiles — in fact, he sees Icke’s Jewish alien lizards as a Masonic plot to divert observers from the true earthly enemies: remnants of the Third Reich. He even used the mural’s sword-wielding military figure as the front cover of his 2001 book, Death in the Air.

“The Nazi alien symbolizes the Nazi-fascist links between contemporary population controllers and the military-medical-petrochemical-pharmaceutical cartel largely accountable for Hitler’s rise to power,” Horowitz explained in a 2003 interview with BookWire.

…

Although conspiracy theories vary widely, they all share three commonalities. “One is the belief that nothing happens by accident,” [Syracuse University professor Michael Barkun, author of the 2006 book A Culture of Conspiracy] points out. “Another is that everything is connected. And a third is that nothing is as it seems.” [Emphasis added]

…

[Alex] Christopher is a 65-year-old grandmother living in Alabama.

…

Christopher, on the other hand, was open to hearing anything. A man called her and said he had found an elevator at DIA that led to a corridor that led all the way down into a military base that also contained alien-operated concentration camps. She detailed this theory in her next book, Pandora’s Box II…

And the scale of DIA reflected this desire: It was to be the largest, most modern airport in the world. But almost as soon as ground was broken in 1989, problems cropped up. The massive public-works project was encumbered by design changes, difficult airline negotiations, allegations of cronyism in the contracting process, rumors of mismanagement and real troubles with the $700 million (and eventually abandoned) automated baggage system. Peña’s successor, Wellington Webb, was forced to push back the 1993 opening date three times. By the time DIA finally opened in February 1995, the original $1.5 billion cost had grown to $5.2 billion. Three months after that opening, the Congressional Subcommittee on Aviation held a special hearing on DIA in which one member said the Denver airport represented the “worst in government inefficiency, political behind-the-scenes deal-making, and financial mismanagement.” …

And what looked like a gamble in 1995 seems to have paid off for Denver. Today, DIA is considered one of the world’s most efficient, spacious and technologically advanced airports. It is the fifth-busiest in the nation and tenth-busiest in the world, serving some 50 million passengers in 2006.

Matthew, the blind phone phreaker

history, law, security, tech in changing society / /

From Kevin Poulsen’s “Teenage Hacker Is Blind, Brash and in the Crosshairs of the FBI” (Wired: 29 February 2008):

At 4 in the morning of May 1, 2005, deputies from the El Paso County Sheriff’s Office converged on the suburban Colorado Springs home of Richard Gasper, a TSA screener at the local Colorado Springs Municipal Airport. They were expecting to find a desperate, suicidal gunman holding Gasper and his daughter hostage.

“I will shoot,” the gravely voice had warned, in a phone call to police minutes earlier. “I’m not afraid. I will shoot, and then I will kill myself, because I don’t care.”

But instead of a gunman, it was Gasper himself who stepped into the glare of police floodlights. Deputies ordered Gasper’s hands up and held him for 90 minutes while searching the house. They found no armed intruder, no hostages bound in duct tape. Just Gasper’s 18-year-old daughter and his baffled parents.

A federal Joint Terrorism Task Force would later conclude that Gasper had been the victim of a new type of nasty hoax, called “swatting,” that was spreading across the United States. Pranksters were phoning police with fake murders and hostage crises, spoofing their caller IDs so the calls appear to be coming from inside the target’s home. The result: police SWAT teams rolling to the scene, sometimes bursting into homes, guns drawn.

Now the FBI thinks it has identified the culprit in the Colorado swatting as a 17-year-old East Boston phone phreak known as “Li’l Hacker.” Because he’s underage, Wired.com is not reporting Li’l Hacker’s last name. His first name is Matthew, and he poses a unique challenge to the federal justice system, because he is blind from birth.

…

Interviews by Wired.com with Matt and his associates, and a review of court documents, FBI reports and audio recordings, paints a picture of a young man with an uncanny talent for quick telephone con jobs. Able to commit vast amounts of information to memory instantly, Matt has mastered the intricacies of telephone switching systems, while developing an innate understanding of human psychology and organization culture — knowledge that he uses to manipulate his patsies and torment his foes.

…

Matt says he ordered phone company switch manuals off the internet and paid to have them translated into Braille. He became a regular caller to internal telephone company lines, where he’d masquerade as an employee to perform tricks like tracing telephone calls, getting free phone features, obtaining confidential customer information and disconnecting his rivals’ phones.

It was, relatively speaking, mild stuff. The teen though, soon fell in with a bad crowd. The party lines were dominated by a gang of half-a-dozen miscreants who informally called themselves the “Wrecking Crew” and “The Cavalry.”
…

By then, Matt’s reputation had taken on a life of its own, and tales of some of his hacks — perhaps apocryphal — are now legends. According to Daniels, he hacked his school’s PBX so that every phone would ring at once. Another time, he took control of a hotel elevator, sending it up and down over and over again. One story has it that Matt phoned a telephone company frame room worker at home in the middle of the night, and persuaded him to get out of bed and return to work to disconnect someone’s phone.

How con artists use psychology to work

1 Comment / business, science, security / /

From Paul J. Zak’s “How to Run a Con” (Psychology Today: 13 November 2008):

When I was in high school, I took a job at an ARCO gas station on the outskirts of Santa Barbara, California. At the time, I drove a 1967 Mustang hotrod and thought I might pick up some tips and cheap parts by working around cars after school. You see a lot of interesting things working the night shift in a sketchy neighborhood. I constantly saw people making bad decisions: drunk drivers, gang members, unhappy cops, and con men. In fact, I was the victim of a classic con called “The Pigeon Drop.” If we humans have such big brains, how can we get conned?

Here’s what happened to me. One slow Sunday afternoon, a man comes out of the restroom with a pearl necklace in his hand. “Found it on the bathroom floor” he says. He followed with “Geez, looks nice-I wonder who lost it?” Just then, the gas station’s phone rings and a man asked if anyone found a pearl necklace that he had purchased as a gift for his wife. He offers a $200 reward for the necklace’s return. I tell him that a customer found it. “OK” he says, “I’ll be there in 30 minutes.” I give him the ARCO address and he gives me his phone number. The man who found the necklace hears all this but tells me he is running late for a job interview and cannot wait for the other man to arrive.

Huum, what to do? The man with the necklace said “Why don’t I give you the necklace and we split the reward?” The greed-o-meter goes off in my head, suppressing all rational thought. “Yeah, you give me the necklace to hold and I’ll give you $100” I suggest. He agrees. Since high school kids working at gas stations don’t have $100, I take money out of the cash drawer to complete the transaction.

You can guess the rest. The man with the lost necklace doesn’t come and never answers my many calls. After about an hour, I call the police. The “pearl” necklace was a two dollar fake and the number I was calling went to a pay phone nearby. I had to fess up to my boss and pay back the money with my next paycheck.

Why did this con work? Let’s do some neuroscience. While the primary motivator from my perspective was greed, the pigeon drop cleverly engages THOMAS (The Human Oxytocin Mediated Attachment System). … THOMAS is a powerful brain circuit that releases the neurochemical oxytocin when we are trusted and induces a desire to reciprocate the trust we have been shown–even with strangers.

The key to a con is not that you trust the conman, but that he shows he trusts you. Conmen ply their trade by appearing fragile or needing help, by seeming vulnerable. Because of THOMAS, the human brain makes us feel good when we help others–this is the basis for attachment to family and friends and cooperation with strangers. “I need your help” is a potent stimulus for action.

50% of people infected with personality-changing brain parasites from cats

science, weird / /

From Carl Zimmer’s “The Return of the Puppet Masters” (Corante: 17 January 2006):

I was investigating the remarkable ability parasites have to manipulate the behavior of their hosts. The lancet fluke Dicrocoelium dendriticum, for example, forces its ant host to clamp itself to the tip of grass blades, where a grazing mammal might eat it. It’s in the fluke’s interest to get eaten, because only by getting into the gut of a sheep or some other grazer can it complete its life cycle. Another fluke, Euhaplorchis californiensis, causes infected fish to shimmy and jump, greatly increasing the chance that wading birds will grab them.

Those parasites were weird enough, but then I got to know Toxoplasma gondii. This single-celled parasite lives in the guts of cats, sheddding eggs that can be picked up by rats and other animals that can just so happen be eaten by cats. Toxoplasma forms cysts throughout its intermediate host’s body, including the brain. And yet a Toxoplasma-ridden rat is perfectly healthy. That makes good sense for the parasite, since a cat would not be particularly interested in eating a dead rat. But scientists at Oxford discovered that the parasite changes the rats in one subtle but vital way.

The scientists studied the rats in a six-foot by six-foot outdoor enclosure. They used bricks to turn it into a maze of paths and cells. In each corner of the enclosure they put a nest box along with a bowl of food and water. On each the nests they added a few drops of a particular odor. On one they added the scent of fresh straw bedding, on another the bedding from a rat’s nests, on another the scent of rabbit urine, on another, the urine of a cat. When they set healthy rats loose in the enclosure, the animals rooted around curiously and investigated the nests. But when they came across the cat odor, they shied away and never returned to that corner. This was no surprise: the odor of a cat triggers a sudden shift in the chemistry of rat brains that brings on intense anxiety. (When researchers test anti-anxiety drugs on rats, they use a whiff of cat urine to make them panic.) The anxiety attack made the healthy rats shy away from the odor and in general makes them leery of investigating new things. Better to lie low and stay alive.

Then the researchers put Toxoplasma-carrying rats in the enclosure. Rats carrying the parasite are for the most part indistinguishable from healthy ones. They can compete for mates just as well and have no trouble feeding themselves. The only difference, the researchers found, is that they are more likely to get themselves killed. The scent of a cat in the enclosure didn’t make them anxious, and they went about their business as if nothing was bothering them. They would explore around the odor at least as often as they did anywhere else in the enclosure. In some cases, they even took a special interest in the spot and came back to it over and over again.

The scientists speculated that Toxoplasma was secreted some substance that was altering the patterns of brain activity in the rats. This manipulation likely evolved through natural selection, since parasites that were more likely to end up in cats would leave more offpsring.

The Oxford scientists knew that humans can be hosts to Toxoplasma, too. People can become infected by its eggs by handling soil or kitty litter. For most people, the infection causes no harm. Only if a person’s immune system is weak does Toxoplasma grow uncontrollably. That’s why pregnant women are advised not to handle kitty litter, and why toxoplasmosis is a serious risk for people with AIDS. Otherwise, the parasite lives quietly in people’s bodies (and brains). It’s estimated that about half of all people on Earth are infected with Toxoplasma.

…

Parasitologist Jaroslav Flegr of Charles University in Prague administered psychological questionnaires to people infected with Toxoplasma and controls. Those infected, he found, show a small, but statistically significant, tendency to be more self-reproaching and insecure. Paradoxically, infected women, on average, tend to be more outgoing and warmhearted than controls, while infected men tend to be more jealous and suspicious.

… [E. Fuller Torrey of the Stanley Medical Research Institute in Bethesda, Maryland] and his colleagues had noticed some intriguing links between Toxoplasma and schizophrenia. Infection with the parasite has been associated with damage to a certain class of neurons (astrocytes). So has schizophrenia. Pregnant women with high levels of Toxoplasma antibodies in their blood were more likely to give birth to children who would later develop schizophrenia. Torrey lays out more links in this 2003 paper. While none is a smoking gun, they are certainly food for thought. It’s conceivable that exposure to Toxoplasma causes subtle changes in most people’s personality, but in a small minority, it has more devastating effects.

The various participants in phishing schemes

business, law, security, tech in changing society / /

From Chapter 2: Botnets Overview of Craig A. Schiller’s Botnets: The Killer Web App (Syngress: 2007):

Christopher Abad provides insight into the phishing economy in an article published online by FirstMonday.org (http://www.firstmonday.org/issues/ issue10_9/abad/). The article, “The economy of phishing: A survey of the operations of the phishing market,” reveals the final phase of the phishing life cycle, called cashing. These are usually not the botherders or the phishers. The phishers are simply providers of credential goods to the cashers. Cashers buy the credential goods from the phishers, either taking a commission on the funds extracted or earned based on the quality, completeness, which financial institution it is from, and the victim’s balance in the account. A high-balance, verified, full-credential account can be purchased for up to $100. Full creden- tials means that you have the credit card number, bank and routing numbers, the expiration date, the security verification code (cvv2) on the back of the card, the ATM pin number, and the current balance. Credit card numbers for a financial institution selected by the supplier can be bought for 50 cents per account. The casher’s commission of this transaction may run as much as 70 percent. When the deal calls for commissions to be paid in cash, the vehicle of choice is Western Union.

The continuation of phishing attacks depends largely on the ability of the casher’s to convert the information into cash. The preferred method is to use the credential information to create duplicate ATM cards and use the cards to withdraw cash from ATM terminals. Not surprisingly the demand for these cards leans heavily in favor of banks that provide inadequate protections of the ATM cards. Institutions like Bank of America are almost nonexistent in the phisher marketplace due to the strong encryption (triple DES) used to protect information on its ATM cards.

10,000 hours to reach expertise

art, education, science / /

From Malcolm Gladwell’s “A gift or hard graft?” (The Guardian: 15 November 2008):

This idea – that excellence at a complex task requires a critical, minimum level of practice – surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is a magic number for true expertise: 10,000 hours.

“In study after study, of composers, basketball players, fiction writers, ice-skaters, concert pianists, chess players, master criminals,” writes the neurologist Daniel Levitin, “this number comes up again and again. Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years… No one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.”

Thinking like an engineer; thinking like a security pro

security / /

From Bruce Schneier’s “Inside the Twisted Mind of the Security Professional” (Wired: 20 March 2008):

This kind of thinking is not natural for most people. It’s not natural for engineers. Good engineering involves thinking about how things can be made to work; the security mindset involves thinking about how things can be made to fail. It involves thinking like an attacker, an adversary or a criminal. You don’t have to exploit the vulnerabilities you find, but if you don’t see the world that way, you’ll never notice most security problems.

Bush’s Manicheanism destroyed him

1 Comment / history, law, politics / /

From Glenn Greenwald’s “A tragic legacy: How a good vs. evil mentality destroyed the Bush presidency” (Salon: 20 June 2007):

One of the principal dangers of vesting power in a leader who is convinced of his own righteousness — who believes that, by virtue of his ascension to political power, he has been called to a crusade against Evil — is that the moral imperative driving the mission will justify any and all means used to achieve it. Those who have become convinced that they are waging an epic and all-consuming existential war against Evil cannot, by the very premises of their belief system, accept any limitations — moral, pragmatic, or otherwise — on the methods adopted to triumph in this battle.

Efforts to impose limits on waging war against Evil will themselves be seen as impediments to Good, if not as an attempt to aid and abet Evil. In a Manichean worldview, there is no imperative that can compete with the mission of defeating Evil. The primacy of that mandate is unchallengeable. Hence, there are no valid reasons for declaring off-limits any weapons that can be deployed in service of the war against Evil.

Equally operative in the Manichean worldview is the principle that those who are warriors for a universal Good cannot recognize that the particular means they employ in service of their mission may be immoral or even misguided. The very fact that the instruments they embrace are employed in service of their Manichean mission renders any such objections incoherent. How can an act undertaken in order to strengthen the side of Good, and to weaken the forces of Evil, ever be anything other than Good in itself? Thus, any act undertaken by a warrior of Good in service of the war against Evil is inherently moral for that reason alone.

It is from these premises that the most amoral or even most reprehensible outcomes can be — and often are — produced by political movements and political leaders grounded in universal moral certainties. Intoxicated by his own righteousness and therefore immune from doubt, the Manichean warrior becomes capable of acts of moral monstrousness that would be unthinkable in the absence of such unquestionable moral conviction. One who believes himself to be leading a supreme war against Evil on behalf of Good will be incapable of understanding any claims that he himself is acting immorally.

…

That is the essence of virtually every argument Bush supporters make regarding terrorism. No matter what objection is raised to the never-ending expansions of executive power, no matter what competing values are touted (due process, the rule of law, the principles our country embodies, how we are perceived around the world), the response will always be that The Terrorists are waging war against us and our overarching priority — one that overrides all others — is to protect ourselves, to triumph over Evil. By definition, then, there can never be any good reason to oppose vesting powers in the government to protect us from The Terrorists because that goal outweighs all others.

But our entire system of government, from its inception, has been based upon a very different calculus — that is, that many things matter besides merely protecting ourselves against threats, and consequently, we are willing to accept risks, even potentially fatal ones, in order to secure those other values. From its founding, America has rejected the worldview of prioritizing physical safety above all else, as such a mentality leads to an impoverished and empty civic life. The premise of America is and always has been that imposing limitations on government power is necessary to secure liberty and avoid tyranny even if it means accepting an increased risk of death as a result. That is the foundational American value.

It is this courageous demand for core liberties even if such liberties provide less than maximum protection from physical risks that has made America bold, brave, and free. Societies driven exclusively or primarily by a fear of avoiding Evil, minimizing risks, and seeking above all else that our government “protects” us are not free. That is a path that inevitably leads to authoritarianism — an increasingly strong and empowered leader in whom the citizens vest ever-increasing faith and power in exchange for promises of safety. That is most assuredly not the historical ethos of the United States.

The Bill of Rights contains numerous limitations on government power, and many of them render us more vulnerable to threats. If there is a serial killer on the loose in a community, the police would be able to find and apprehend him much more easily if they could simply invade and search everyone’s homes at will and without warning. Nonetheless, the Fourth Amendment expressly prohibits the police from undertaking such searches. It requires both probable cause and a judicial warrant before police may do so, even though such limitations on state power will enable dangerous killers to elude capture.

…

The scare tactic of telling Americans that every desired expansion of government power is justified by the Evil Terrorist Threat — and that there is no need to worry because the president is Good and will use these powers only to protect us — is effective because it has immediate rhetorical appeal. Most people, especially when placed in fear of potentially fatal threats, are receptive to the argument that maximizing protection is the only thing that matters, and that no abstract concept (such as liberty, or freedom, or due process, or adhering to civilized norms) is worth risking one’s life by accepting heightened levels of vulnerability.

But nothing in life is perfectly safe. Perfect safety is an illusion. When pursued by an individual to the exclusion of all else, it creates a tragically worthless, paralyzed way of life. On the political level, safety as the paramount goal produces tyranny, causing people to vest as much power as possible in the government, without limits, in exchange for the promise of maximum protection.

Correcting wrong info reinforces false beliefs

education, history, politics, science / /

From Jonathan M. Gitlin’s “Does ideology trump facts? Studies say it often does” (Ars Technica: 24 September 2008):

We like to think that people will be well informed before making important decisions, such as who to vote for, but the truth is that’s not always the case. Being uninformed is one thing, but having a population that’s actively misinformed presents problems when it comes to participating in the national debate, or the democratic process. If the findings of some political scientists are right, attempting to correct misinformation might do nothing more than reinforce the false belief.

This sort of misinformation isn’t hypothetical; in 2003 a study found that viewers of Fox News were significantly more misinformed about the Iraq war, with far greater percentages of viewers erroneously believing that Iraq possessed WMDs or that there was a credible link between the 9/11 attack and Saddam Hussein than those who got their news from other outlets like NPR and PBS. This has led to the rise of websites like FactCheck and SourceWatch.

Saying that correcting misinformation does little more than reinforce a false belief is a pretty controversial proposal, but the claim is based on a number of studies that examine the effect of political or ideological bias on fact correction. In the studies, volunteers were shown news items or political adverts that contained misinformation, followed by a correction. For example, a study by John Bullock of Yale showed volunteers a political ad created by NARAL that linked Justice John Roberts to a violent anti-abortion group, followed by news that the ad had been withdrawn. Interestingly, Democratic participants had a worse opinion of Roberts after being shown the ad, even after they were told it was false.

Over half (56 percent) of Democratic subjects disapproved of Roberts before the misinformation. That rose to 80 percent afterward, but even after correcting the misinformation, 72 percent of Democratic subjects still had a negative opinion. Republican volunteers, on the other hand, only showed a small increase in disapproval after watching the misinformation (11 percent vs 14 percent).

Bruno’s memory structures

education, history / /

From Laura Miller’s “The heretic” (Salon: 25 August 2008):

Still, the mental powers of Bruno and his fellow memory artists seem almost superhuman today. The basic principle, Rowland explains, is simple enough, “to link words with images.” Nevertheless, the structures employed were mind-boggling: vast, elaborate patterns and nested wheels within wheels (like the color wheels used by visual designers) that could be used to juxtapose and rearrange huge quantities of information without recourse to any extra-mental form of storage (like writing). This ability makes the minds of Renaissance intellectuals radically different from our own, almost incomprehensibly so.
