Finding Sociopaths on Facebook

On his blog, Scott Adams suggests that it might be possible to identify sociopaths based on their interactions on social media.

My hypothesis is that science will someday be able to identify sociopaths and terrorists by their patterns of Facebook and Internet use. I’ll bet normal people interact with Facebook in ways that sociopaths and terrorists couldn’t duplicate.

Anyone can post fake photos and acquire lots of friends who are actually acquaintances. But I’ll bet there are so many patterns and tendencies of “normal” use on Facebook that a terrorist wouldn’t be able to successfully fake it.

Okay, but so what? Imagine you had such an amazingly accurate test…then what? Do we investigate those who test positive, even though there’s no suspicion that they’ve actually done anything? Do we follow them around? Subject them to additional screening at airports? Throw them in jail because we know the streets will be safer because of it? Do we want to live in a Minority Report world?

The problem isn’t just that such a system is wrong, it’s that the mathematics of testing makes this sort of thing pretty ineffective in practice. It’s called the “base rate fallacy.” Suppose you have a test that’s 90% accurate in identifying both sociopaths and non-sociopaths. If you assume that 4% of people are sociopaths, then the chance of someone who tests positive actually being a sociopath is 26%. (For every thousand people tested, 90% of the 40 sociopaths will test positive, but so will 10% of the 960 non-sociopaths.) You have postulate a test with an amazing 99% accuracy—only a 1% false positive rate—even to have an 80% chance of someone testing positive actually being a sociopath.

This fallacy isn’t new. It’s the same thinking that caused us to intern Japanese-Americans during World War II, stop people in their cars because they’re black, and frisk them at airports because they’re Muslim. It’s the same thinking behind massive NSA surveillance programs like PRISM. It’s one of the things that scares me about police DNA databases.

Many authors have written stories about thoughtcrime. Who has written about genecrime?

BTW, if you want to meet an actual sociopath, I recommend this book (review here) and this blog.

DDOS as Civil Disobedience

For a while now, I have been thinking about what civil disobedience looks like in the Internet Age. Certainly DDOS attacks, and politically motivated hacking in general, is a part of that. This is one of the reasons I found Molly Sauter’s recent thesis, “Distributed Denial of Service Actions and the Challenge of Civil Disobedience on the Internet,” so interesting:

Abstract: This thesis examines the history, development, theory, and practice of distributed denial of service actions as a tactic of political activism. DDOS actions have been used in online political activism since the early 1990s, though the tactic has recently attracted significant public attention with the actions of Anonymous and Operation Payback in December 2010. Guiding this work is the overarching question of how civil disobedience and disruptive activism can be practiced in the current online space. The internet acts as a vital arena of communication, self expression, and interpersonal organizing. When there is a message to convey, words to get out, people to organize, many will turn to the internet as the zone of that activity. Online, people sign petitions, investigate stories and rumors, amplify links and videos, donate money, and show their support for causes in a variety of ways. But as familiar and widely accepted activist tools—petitions, fundraisers, mass letter-writing, call-in campaigns and others—find equivalent practices in the online space, is there also room for the tactics of disruption and civil disobedience that are equally familiar from the realm of street marches, occupations, and sit-ins? This thesis grounds activist DDOS historically, focusing on early deployments of the tactic as well as modern instances to trace its development over time, both in theory and in practice. Through that examination, as well as tool design and development, participant identity, and state and corporate responses, this thesis presents an account of the development and current state of activist DDOS actions. It ends by presenting an analytical framework for the analysis of activist DDOS actions.

One of the problems with the legal system is that it doesn’t make any differentiation between civil disobedience and “normal” criminal activity on the Internet, though it does in the real world.

Security Risks of Too Much Security

All of the anti-counterfeiting features of the new Canadian $100 bill are resulting in people not bothering to verify them.

The fanfare about the security features on the bills, may be part of the problem, said RCMP Sgt. Duncan Pound.

“Because the polymer series’ notes are so secure … there’s almost an overconfidence among retailers and the public in terms of when you sort of see the strip, the polymer looking materials, everybody says ‘oh, this one’s going to be good because you know it’s impossible to counterfeit,'” he said.

“So people don’t actually check it.”

Details of a Cyberheist

Really interesting article detailing how criminals steal from a company’s accounts over the Internet.

The costly cyberheist was carried out with the help of nearly 100 different accomplices in the United States who were hired through work-at-home job scams run by a crime gang that has been fleecing businesses for the past five years.

Basically, the criminals break into the bank account, move money into a bunch of other bank accounts, and use unwitting accomplices to launder the money.

The publication said the attack occurred on Apr. 19, and moved an estimated $1.03 million out of the hospital’s payroll account into 96 different bank accounts, mostly at banks in the Midwest and East Coast.

Britain's Prince Philip on Security

On banning guns:

“If a cricketer, for instance, suddenly decided to go into a school and batter a lot of people to death with a cricket bat,which he could do very easily, I mean, are you going to ban cricket bats?” In a Radio 4 interview shortly after the Dunblane shootings in 1996. He said to the interviewer off-air afterwards: “That will really set the cat among the pigeons, won’t it?”

"Raise the Crime Rate"

I read this a couple of months ago, and I’m still not sure what I think about it. It’s definitely one of the most thought-provoking essays I’ve read this year.

According to government statistics, Americans are safer today than at any time in the last forty years. In 1990, there were 2,245 homicides in New York City. In 2010, there were 536, only 123 of which involved people who didn’t already know each other. The fear, once common, that walking around city parks late at night could get you mugged or murdered has been relegated to grandmothers; random murders, with few exceptions, simply don’t happen anymore.

When it comes to rape, the numbers look even better: from 1980 to 2005, the estimated number of sexual assaults in the US fell by 85 percent. Scholars attribute this stunning collapse to various factors, including advances in gender equality, the abortion of unwanted children, and the spread of internet pornography.

It shouldn’t surprise us that the country was more dangerous in 1990, at the height of the crack epidemic, than in 2006, at the height of the real estate bubble. What’s strange is that crime has continued to fall during the recession. On May 23, in what has become an annual ritual, the New York Times celebrated the latest such finding: in 2010, as America’s army of unemployed grew to 14 million, violent crime fell for the fourth year in a row, sinking to a level not seen since the early ’70s. This seemed odd. Crime and unemployment were supposed to rise in tandem­progressives have been harping on this point for centuries. Where had all the criminals gone?

Statistics are notoriously slippery, but the figures that suggest that violence has been disappearing in the United States contain a blind spot so large that to cite them uncritically, as the major papers do, is to collude in an epic con. Uncounted in the official tallies are the hundreds of thousands of crimes that take place in the country’s prison system, a vast and growing residential network whose forsaken tenants increasingly bear the brunt of America’s propensity for anger and violence.

Crime has not fallen in the United States—it’s been shifted. Just as Wall Street connived with regulators to transfer financial risk from spendthrift banks to careless home buyers, so have federal, state, and local legislatures succeeded in rerouting criminal risk away from urban centers and concentrating it in a proliferating web of hyperhells. The statistics touting the country’s crime-reduction miracle, when juxtaposed with those documenting the quantity of rape and assault that takes place each year within the correctional system, are exposed as not merely a lie, or even a damn lie—but as the single most shameful lie in American life.

The author argues that the only moral thing for the U.S. to do is to accept a slight rise in the crime rate while vastly reducing the number of people incarcerated.

While I might not agree with his conclusion—as I said above, I’m not sure whether I do or I don’t—it’s very much the sort of trade-off I talk about in Liars and Outliers. And Steven Pinker has an extensive argument about violent crime in modern society that he makes in The Better Angels of our Nature.

Prisons in the U.S.

Really good article on the huge incarceration rate in the U.S., its causes, its effects, and its value:

Over all, there are now more people under “correctional supervision” in America—more than six million—than were in the Gulag Archipelago under Stalin at its height. That city of the confined and the controlled, Lockuptown, is now the second largest in the United States.

The accelerating rate of incarceration over the past few decades is just as startling as the number of people jailed: in 1980, there were about two hundred and twenty people incarcerated for every hundred thousand Americans; by 2010, the number had more than tripled, to seven hundred and thirty-one. No other country even approaches that. In the past two decades, the money that states spend on prisons has risen at six times the rate of spending on higher education.

[…]

The trouble with the Bill of Rights, he argues, is that it emphasizes process and procedure rather than principles. The Declaration of the Rights of Man says, Be just! The Bill of Rights says, Be fair! Instead of announcing general principles­—no one should be accused of something that wasn’t a crime when he did it; cruel punishments are always wrong; the goal of justice is, above all, that justice be done­—it talks procedurally. You can’t search someone without a reason; you can’t accuse him without allowing him to see the evidence; and so on. This emphasis, Stuntz thinks, has led to the current mess, where accused criminals get laboriously articulated protection against procedural errors and no protection at all against outrageous and obvious violations of simple justice. You can get off if the cops looked in the wrong car with the wrong warrant when they found your joint, but you have no recourse if owning the joint gets you locked up for life. You may be spared the death penalty if you can show a problem with your appointed defender, but it is much harder if there is merely enormous accumulated evidence that you weren’t guilty in the first place and the jury got it wrong. Even clauses that Americans are taught to revere are, Stuntz maintains, unworthy of reverence: the ban on “cruel and unusual punishment” was designed to protect cruel punishments—flogging and branding—that were not at that time unusual.

The author mentions the rise of for-profit businesses increasingly running prisons in the U.S., but I don’t think he makes the point strongly enough. There is now a corporate interest in the U.S. lobbying for such things as mandatory minimum sentencing.

The Idaho Loophole

Brian C. Kalt (2005), “The Perfect Crime,” Georgetown Law Journal, Vol. 93, No. 2.

Abstract: This article argues that there is a 50-square-mile swath of Idaho in which one can commit felonies with impunity. This is because of the intersection of a poorly drafted statute with a clear but neglected constitutional provision: the Sixth Amendment’s Vicinage Clause. Although lesser criminal charges and civil liability still loom, the remaining possibility of criminals going free over a needless technical failure by Congress is difficult to stomach. No criminal defendant has ever broached the subject, let alone faced the numerous (though unconvincing) counterarguments. This shows that vicinage is not taken seriously by lawyers or judges. Still, Congress should close the Idaho loophole, not pretend it does not exist.

Detecting Psychopaths by their Speech Patterns

Interesting:

The researchers interviewed 52 convicted murderers, 14 of them ranked as psychopaths according to the Psychopathy Checklist-Revised, a 20-item assessment, and asked them to describe their crimes in detail. Using computer programs to analyze what the men said, the researchers found that those with psychopathic scores showed a lack of emotion, spoke in terms of cause-and-effect when describing their crimes, and focused their attention on basic needs, such as food, drink and money.

[…]

To examine the emotional content of the murderers’ speech, Hancock and his colleagues looked at a number of factors, including how frequently they described their crimes using the past tense. The use of the past tense can be an indicator of psychological detachment, and the researchers found that the psychopaths used it more than the present tense when compared with the nonpsychopaths. They also found more dysfluencies—the “uhs” and “ums” that interrupt speech—among psychopaths. Nearly universal in speech, dysfluencies indicate that the speaker needs some time to think about what they are saying.

I worry about people being judged by these criteria. Psychopaths make up about 1% of the population, so even a small false-positive rate can be a significant problem.
