Another Liars and Outliers Review

I was reviewed in Science:

Thus it helps to have a lucid and informative account such as Bruce Schneier’s Liars and Outliers. The book provides an interesting and entertaining summary of the state of play of research on human social behavior, with a special emphasis on trust and trustworthiness.

[…]

Free from preoccupations and personal attachments to any of the scientific disciplines working on the topic, he has compiled a well-structured overview of what research can tell us about how trust and trustworthiness accumulate (although some academic readers may find their publications presented in an unexpected context). This he enlivens by adding real-life experiences on how to build trust and keep trustworthiness alive.

I am amused by the parenthetical comment.

Police Sting Operation Yields No Mobile Phone Thefts

Police in Hastings, in the UK, outfitted mobile phones with tracking devices and left them in bars and restaurants, hoping to catch mobile phone thieves in the act. But no one stole them:

Nine premises were visited in total and officers were delighted that not one of the bait phones was ‘stolen’. In fact, on nearly every occasion good hearted members of the public handed them to bar or security staff.

I’m not sure about the headline: “Operation Mobli deters mobile phone thieves in Hastings.”

There are two things going on here. One, people are generally nice and will return property to its rightful owner. Two, it’s hard for the average person to profit from a stolen cell phone. He already has a cell phone that’s assigned to his phone number. He doesn’t really know if he can sell a random phone, especially one assigned to the number of someone who had her phone stolen. Yes, professional phone thieves know what to do, but what’s the odds that one of those is dining out in Hastings on a particular night?

Honor System Farm Stands

Many roadside farm stands in the U.S. are unstaffed. They work on the honor system: take what you want, and pay what you owe.

And today at his farm stand, Cochran says, just as at the donut shop years ago, most customers leave more money than they owe.

That doesn’t surprise social psychologist Michael Cunningham of the University of Louisville who has used “trust games” to investigate what spurs good and bad behavior for the last 25 years. For many people, Cunningham says, trust seems to be at least as strong a motivator as guilt. He thinks he knows why.

“When you sell me something I want and trust me to pay you even when you’re not looking, you’ve made my life good in two ways,” Cunningham tells The Salt. “I get something delicious, and I also get a good feeling about myself. Both of those things make me feel good about the world­ that I’m in a good place. And I also see you as a contributor to that good ­ as somebody I want to reward. It’s a win win.”

I like systems that leverage personal moral codes for security. But I’ll bet that the pay boxes are bolted to the tables. It’s one thing for someone to take produce without paying. It’s quite another for him to take the entire day’s receipts.

Lessons in Trust from Web Hoaxes

Interesting discussion of trust in this article on web hoaxes.

Kelly’s students, like all good con artists, built their stories out of small, compelling details to give them a veneer of veracity. Ultimately, though, they aimed to succeed less by assembling convincing stories than by exploiting the trust of their marks, inducing them to lower their guard. Most of us assess arguments, at least initially, by assessing those who make them. Kelly’s students built blogs with strong first-person voices, and hit back hard at skeptics. Those inclined to doubt the stories were forced to doubt their authors. They inserted articles into Wikipedia, trading on the credibility of that site. And they aimed at very specific communities: the “beer lovers of Baltimore” and Reddit.

That was where things went awry. If the beer lovers of Baltimore form a cohesive community, the class failed to reach it. And although most communities treat their members with gentle regard, Reddit prides itself on winnowing the wheat from the chaff. It relies on the collective judgment of its members, who click on arrows next to contributions, elevating insightful or interesting content, and demoting less worthy contributions. Even Mills says he was impressed by the way in which redditors “marshaled their collective bits of expert knowledge to arrive at a conclusion that was largely correct.” It’s tough to con Reddit.

[…]

If there’s a simple lesson in all of this, it’s that hoaxes tend to thrive in communities which exhibit high levels of trust. But on the Internet, where identities are malleable and uncertain, we all might be well advised to err on the side of skepticism.

Kip Hawley Reviews Liars and Outliers

In his blog:

I think the most important security issues going forward center around identity and trust. Before knowing I would soon encounter Bruce again in the media, I bought and read his new book Liars & Outliers and it is a must-read book for people looking forward into our security future and thinking about where this all leads. For my colleagues inside the government working the various identity management, security clearance, and risk-based- security issues, L&O should be required reading.

[…]

L&O is fresh thinking about live fire issues of today as well as moral issues that are ahead. Whatever your policy bent, this book will help you. Trust me on this, you don’t have to buy everything Bruce says about TSA to read this book, take it to work, put it down on the table and say, “this is brilliant stuff.”

I’m hosting Kip Hawley on FireDogLake’s Book Salon on Sunday at 5:00 – 7:00 PM EDT. Join me and we’ll ask him some tough questions about his new book.

Fear and the Attention Economy

danah boyd is thinking about—in a draft essay, and as a recording of a presentation—fear and the attention economy. Basically, she is making the argument that the attention economy magnifies the culture of fear because fear is a good way to get attention, and that this is being made worse by the rise of social media.

A lot of this isn’t new. Fear has been used to sell products (I’ve written about that here) and policy (“Remember the Maine!” “Remember the Alamo! “Remember 9/11!”) since forever. Newspapers have used fear to attract readers since there were readers. Long before there were child predators on the Internet, irrational panics swept society. Shark attacks in the 1970s. Marijuana in the 1950s. boyd relates a story from Glassner’s The Culture of Fear about elderly women being mugged in the 1990s.

These fears have largely been driven from the top down: from political leaders, from the news media. What’s new today—and I agree this is very interesting—is that in addition to these traditional top-down fears, we’re also seeing fears come from the bottom up. Social media are allowing all of us to sow fear and, because fear gets attention, is enticing us to do so. Rather than fostering empathy and bringing us all together, social media might be pushing us further apart.

A lot of this is related to my own writing about trust. Fear causes us to mistrust a group we’re fearful of, and to more strongly trust the group we’re a part of. It’s natural, and it can be manipulated. It can be amplified, and it can be dampened. How social media are both enabling and undermining trust is a really important thing for us to understand. As boyd says: “What we design and how we design it matters. And how our systems are used also matters, even if those uses aren’t what we intended.”

Amazing Round of "Split or Steal"

In Liars and Outliers, I use the metaphor of the Prisoner’s Dilemma to exemplify the conflict between group interest and self-interest. There are a gazillion academic papers on the Prisoner’s Dilemma from a good dozen different academic disciplines, but the weirdest dataset on real people playing the game is from a British game show called Golden Balls.

In the final round of the game, called “Split or Steal,” two contestants play a one-shot Prisoner’s Dilemma—technically, it’s a variant—choosing to either cooperate (and split a jackpot) or defect (and try to steal it). If one steals and the other splits, the stealer gets the whole jackpot. And, of course, if both contestants steal then both end up with nothing. There are lots of videos from the show on YouTube. (There are even two papers that analyze data from the game.) The videos are interesting to watch, not just to see how players cooperate and defect, but to watch their conversation beforehand and their reactions afterwards. I wrote a few paragraphs about this game for Liars and Outliers, but I ended up deleting them.

This is the weirdest, most surreal round of “Split or Steal” I have ever seen. The more I think about the psychology of it, the more interesting it is. I’ll save my comments for the comments, because I want you to watch it before I say more. Really.

For consistency’s sake in the comments, here are their names. The man on the left is Ibrahim, and the man on the right is Nick.

A Heathrow Airport Story about Trousers

Usually I don’t bother posting random stories about dumb or inconsistent airport security measures. But this one is particularly interesting:

“Sir, your trousers.”

“Pardon?”

“Sir, please take your trousers off.”

A pause.

“No.”

“No?”

The security official clearly was not expecting that response.

He begins to look like he doesn’t know what to do, bless him.

“You have no power to require me to do that. You also haven’t also given any good reason. I am sure any genuine security concerns you have can be addressed in other ways. You do not need to invade my privacy in this manner.”

A pause.

“I think you probably need to get your manager, don’t you?” I am trying to be helpful.

As I said in my Economist essay, “At this point, we don’t trust America’s TSA, Britain’s Department for Transport, or airport security in general.” We don’t trust that, when they tell us to do something and claim it’s essential for security, they’re tellling the truth.

Lost Smart Phones and Human Nature

Symantec deliberately “lost” a bunch of smart phones with tracking software on them, just to see what would happen:

Some 43 percent of finders clicked on an app labeled “online banking.” And 53 percent clicked on a filed named “HR salaries.” A file named “saved passwords” was opened by 57 percent of finders. Social networking tools and personal e-mail were checked by 60 percent. And a folder labeled “private photos” tempted 72 percent.

Collectively, 89 percent of finders clicked on something they probably shouldn’t have.

Meanwhile, only 50 percent of finders offered to return the gadgets, even though the owner’s name was listed clearly within the contacts file.

[…]

Some might consider the 50 percent return rate a victory for humanity, but that wasn’t really the point of Symantec’s project. The firm wanted to see if—even among what seem to be honest people—the urge to peek into someone’s personal data was just too strong to resist. It was.

Harms of Post-9/11 Airline Security

As I posted previously, I have been debating former TSA Administrator Kip Hawley on the Economist website. I didn’t bother reposting my opening statement and rebuttal, because—even though I thought I did a really good job with them—they were largely things I’ve said before. In my closing statement, I talked about specific harms post-9/11 airport security has caused. This is mostly new, so here it is, British spelling and punctuation and all.


In my previous two statements, I made two basic arguments about post-9/11 airport security. One, we are not doing the right things: the focus on airports at the expense of the broader threat is not making us safer. And two, the things we are doing are wrong: the specific security measures put in place since 9/11 do not work. Kip Hawley doesn’t argue with the specifics of my criticisms, but instead provides anecdotes and asks us to trust that airport security—and the Transportation Security Administration (TSA) in particular—knows what it’s doing.

He wants us to trust that a 400-ml bottle of liquid is dangerous, but transferring it to four 100-ml bottles magically makes it safe. He wants us to trust that the butter knives given to first-class passengers are nevertheless too dangerous to be taken through a security checkpoint. He wants us to trust the no-fly list: 21,000 people so dangerous they’re not allowed to fly, yet so innocent they can’t be arrested. He wants us to trust that the deployment of expensive full-body scanners has nothing to do with the fact that the former secretary of homeland security, Michael Chertoff, lobbies for one of the companies that makes them. He wants us to trust that there’s a reason to confiscate a cupcake (Las Vegas), a 3-inch plastic toy gun (London Gatwick), a purse with an embroidered gun on it (Norfolk, VA), a T-shirt with a picture of a gun on it (London Heathrow) and a plastic lightsaber that’s really a flashlight with a long cone on top (Dallas/Fort Worth).

At this point, we don’t trust America’s TSA, Britain’s Department for Transport, or airport security in general. We don’t believe they’re acting in the best interests of passengers. We suspect their actions are the result of politicians and government appointees making decisions based on their concerns about the security of their own careers if they don’t act tough on terror, and capitulating to public demands that “something must be done”.

In this final statement, I promised to discuss the broader societal harms of post-9/11 airport security. This loss of trust—in both airport security and counterterrorism policies in general—is the first harm. Trust is fundamental to society. There is an enormous amount written about this; high-trust societies are simply happier and more prosperous than low-trust societies. Trust is essential for both free markets and democracy. This is why open-government laws are so important; trust requires government transparency. The secret policies implemented by airport security harm society because of their very secrecy.

The humiliation, the dehumanisation and the privacy violations are also harms. That Mr Hawley dismisses these as mere “costs in convenience” demonstrates how out-of-touch the TSA is from the people it claims to be protecting. Additionally, there’s actual physical harm: the radiation from full-body scanners still not publicly tested for safety; and the mental harm suffered by both abuse survivors and children: the things screeners tell them as they touch their bodies are uncomfortably similar to what child molesters say.

In 2004, the average extra waiting time due to TSA procedures was 19.5 minutes per person. That’s a total economic loss—in –America—of $10 billion per year, more than the TSA’s entire budget. The increased automobile deaths due to people deciding to drive instead of fly is 500 per year. Both of these numbers are for America only, and by themselves demonstrate that post-9/11 airport security has done more harm than good.

The current TSA measures create an even greater harm: loss of liberty. Airports are effectively rights-free zones. Security officers have enormous power over you as a passenger. You have limited rights to refuse a search. Your possessions can be confiscated. You cannot make jokes, or wear clothing, that airport security does not approve of. You cannot travel anonymously. (Remember when we would mock Soviet-style “show me your papers” societies? That we’ve become inured to the very practice is a harm.) And if you’re on a certain secret list, you cannot fly, and you enter a Kafkaesque world where you cannot face your accuser, protest your innocence, clear your name, or even get confirmation from the government that someone, somewhere, has judged you guilty. These police powers would be illegal anywhere but in an airport, and we are all harmed—individually and collectively—by their existence.

In his first statement, Mr Hawley related a quote predicting “blood running in the aisles” if small scissors and tools were allowed on planes. That was said by Corey Caldwell, an Association of Flight Attendants spokesman, in 2005. It was not the statement of someone who is thinking rationally about airport security; it was the voice of irrational fear.

Increased fear is the final harm, and its effects are both emotional and physical. By sowing mistrust, by stripping us of our privacy—and in many cases our dignity—by taking away our rights, by subjecting us to arbitrary and irrational rules, and by constantly reminding us that this is the only thing between us and death by the hands of terrorists, the TSA and its ilk are sowing fear. And by doing so, they are playing directly into the terrorists’ hands.

The goal of terrorism is not to crash planes, or even to kill people; the goal of terrorism is to cause terror. Liquid bombs, PETN, planes as missiles: these are all tactics designed to cause terror by killing innocents. But terrorists can only do so much. They cannot take away our freedoms. They cannot reduce our liberties. They cannot, by themselves, cause that much terror. It’s our reaction to terrorism that determines whether or not their actions are ultimately successful. That we allow governments to do these things to us—to effectively do the terrorists’ job for them—is the greatest harm of all.

Return airport security checkpoints to pre-9/11 levels. Get rid of everything that isn’t needed to protect against random amateur terrorists and won’t work against professional al-Qaeda plots. Take the savings thus earned and invest them in investigation, intelligence, and emergency response: security outside the airport, security that does not require us to play guessing games about plots. Recognise that 100% safety is impossible, and also that terrorism is not an “existential threat” to our way of life. Respond to terrorism not with fear but with indomitability. Refuse to be terrorized.

EDITED TO ADD (3/20): Cory Doctorow on the exchange:

All of Hawley’s best arguments sum up to “Someone somewhere did something bad, and if he’d tried it on us, we would have caught him.” His closing clincher? They heard a bad guy was getting on a plane somewhere. The figured out which plane, stopped it from taking off and “resolved” the situation. Seeing as there were no recent reports of foiled terrorist plots, I’m guessing the “resolution” was “it turned out we made a mistake.” But Hawley’s takeaway is: “look at how fast our mistake was!”

EDITED TO ADD (4/19): German translation of the closing statement.
