Modern game theory is generally dated to 1944, with the publication of von Neumann’s “Theory of Games and Economic Behavior,” which imagined human interactions as a series of moves and countermoves aimed at maximizing “payoff.” Since then the discipline has thrived, often dominating political science, economics and biology

But a century and a half earlier, Mr. Chwe argues, Austen was very deliberately trying to lay philosophical groundwork for a new theory of strategic action, sometimes charting territory that today’s theoreticians have themselves failed to reach.

Game theory, he argues, isn’t just part of “hegemonic cold war discourse,” but what the political scientist James Scott called a subversive “weapon of the weak.”

many situations, Mr. Chwe points out, involve parties with unequal levels of strategic thinking. Sometimes a party may simply lack ability. But sometimes a powerful party faced with a weaker one may not realize it even needs to think strategically.

Mr. Chwe, who identifies some 50 “strategic manipulations” in Austen

First among her as yet unequaled concepts is “cluelessness

Even some humanists who admire Mr. Chwe’s work suggest that when it comes to appreciating Austen, social scientists may be the clueless ones. Austen scholars “will not be surprised at all to see the depths of her grasp of strategic thinking and the way she anticipated a 20th-century field of inquiry,”

Google’s latest transparency report shows a sharp rise in requests from governments and courts to take down potentially damaging material.

In Europe, where press freedoms are less sacred and the right to privacy is more ensconced, the idea has taken hold that individuals have a “right to be forgotten,” and those who want their online particulars expunged tend to have the government on their side. In Germany or Spain, Lorraine Martin might have a winning case.

The Connecticut case is just one manifestation of an anxious backlash against the invasive power of the Internet, a world of Big Data and ever more powerful search engines, in which it seems almost everything is permanently recorded and accessible to almost anyone — potential employers, landlords, dates, predators

The Times’s policy is not to censor history, because it’s history. The paper will update an arrest story if presented with evidence of an acquittal or dismissal, completing the story but not deleting the story.

Owen Tripp, a co-founder of Reputation.com, which has made a business out of helping clients manage their digital profile, advocated a “right to be forgotten” in a YouTube video. Tripp said everyone is entitled to a bit of space to grow up, to experiment, to make mistakes.

“This is not just a privacy problem,” said Viktor Mayer-Schönberger, a professor at the Oxford Internet Institute, and author of “Delete: The Virtue of Forgetting in the Digital Age.” “If we are continually reminded about people’s mistakes, we are not able to judge them for who they are in the present. We need some way to put a speed-brake on the omnipresence of the past.”

would like to see search engine companies — the parties that benefit the most financially from amassing our information — offer the kind of reputation-protecting tools that are now available only to those who can afford paid services like those of Reputation.com. Google, he points out, already takes down five million items a week because of claims that they violate copyrights. Why shouldn’t we expect Google to give users an option — and a simple process — to have news stories about them down-ranked or omitted from future search results? Good question. What’s so sacred about a search algorithm, anyway?

search could be – and was – personalised, because Google’s algorithms could figure out what each user was most likely to be interested in, and therefore what kinds of information would be most relevant for her or him. So, imperceptibly, but inexorably over time, we have come to live in what Eli Pariser christened a “filter bubble”.

Before the internet, our problem with information was its scarcity. Now our problem is unmanageable abundance. So now the scarce resources are attention and time, over which a vicious war has broken out between traditional media and the internet-based upstarts.

YouTube has a billion users, half of whom access it via mobile devices. The average time spent on the site is 40 minutes. Facebook now claims to have 1.65 billion monthly active users, who spend on average 50 minutes a day on its services. So if Google is an 800lb gorilla, Facebook is a megaton King Kong.

Competition for attention and time is a zero-sum game that traditional media are losing. In desperation, they are trying both to appease Facebook and to harness its hold on people’s attention

In doing so, they have entered into a truly Faustian bargain. Because while publishers can without difficulty ship their stuff to Instant Articles, they cannot control which ones Facebook users actually get to see. This is because users’ news feeds are determined by Facebook’s machine-learning algorithms that try to guess what each user would like to see (and what might dispose them to click on an advertisement).

when you ask – as Professor George Brock memorably did – whether Mark Zuckerberg and his satraps understand that they have acquired editorial responsibilities, they look blank. Facebook is not a publisher, they explain, merely a “platform”. And, besides, no humans are involved in curating users’ news feeds: it’s all done by algorithms and is therefore neutral. In other words: nothing to see here; move on.

Any algorithm that has to make choices has criteria that are specified by its designers. And those criteria are expressions of human values. Engineers may think they are “neutral”, but long experience has shown us they are babes in the woods of politics, economics and ideology.

The frustration has been compounded by the lack of recourse for Mr. Alefantis, his friends and employees. Yelp blocked the comments sections of Comet Ping Pong’s review page after reports of abusive comments and fake news in reviews. YouTube said it prohibits threats, harassment and hate speech and has tools for flagging violations and filing complaints for the site to take further action, but has largely not blocked comments on these videos. Twitter declined to comment, and Facebook did not have any further comment.

After employees and Mr. Alefantis complained to Reddit about how Comet Ping Pong was being targeted on the site, the #pizzagate discussion thread posted a warning that revealing personal information about individuals was prohibited.“We know that we have more work to do and we take our responsibility to address online abuse seriously,” Reddit said in a statement

“Over 100 likes is good, for me. And comments. You just comment to make a joke or tag someone.”

The best thing is the little notification box, which means someone liked, tagged or followed her on Instagram. She has 604 followers. There are only 25 photos on her page because she deletes most of what she posts. The ones that don’t get enough likes, don’t have good enough lighting or don’t show the coolest moments in her life must be deleted.

Sociologists, advertisers, stock market analysts – everyone wants to know what happens when the generation born glued to screens has to look up and interact with the world.

“It kind of, almost, promotes you as a good person. If someone says, ‘tbh you’re nice and pretty,’ that kind of, like, validates you in the comments. Then people can look at it and say ‘Oh, she’s nice and pretty.’ ”

School is where she thrives: She is beloved by her teachers, will soon star as young Simba in the eighth-grade performance of “The Lion King” musical, and gets straight A’s. Her school doesn’t offer a math course challenging enough for her, so she takes honors algebra online through Johns Hopkins University.

“Happy birthday posts are a pretty big deal,” she says. “It really shows who cares enough to put you on their page.”

He checks the phone bill to see who she’s called and how much she’s been texting, but she barely calls anyone and chats mostly through Snapchat, where her messages disappear.

Some of Katherine’s very best friends have never been to her house, or she to theirs. To Dave, it seems like they rarely hang out, but he knows that to her, it seems like they’re together all the time.

Dave Pommerening wants to figure out how to get her to use it less. One month, she ate up 18 gigabytes of data. Most large plans max out at 10. He intervened and capped her at four GB. “I don’t want to crimp it too much,” he says. “That’s something, from my perspective, I’m going to have to figure out, how to get my arms around that.”

Even if her dad tried snooping around her apps, the true dramas of teenage girl life are not written in the comments. Like how sometimes, Katherine’s friends will borrow her phone just to un-like all the Instagram photos of girls they don’t like. Katherine can’t go back to those girls’ pages and re-like the photos because that would be stalking, which is forbidden.

Or how last week, at the middle school dance, her friends got the phone numbers of 10 boys, but then they had to delete five of them because they were seventh-graders. And before she could add the boys on Snapchat, she realized she had to change her username because it was her childhood nickname and that was totally embarrassing.

Then, because she changed her username, her Snapchat score reverted to zero. The app awards about one point for every snap you send and receive. It’s also totally embarrassing and stressful to have a low Snapchat score. So in one day, she sent enough snaps to earn 1,000 points.

Snapchat is where flirting happens. She doesn’t know anyone who has sent a naked picture to a boy, but she knows it happens with older girls, who know they have met the right guy.

Nothing her dad could find on her phone shows that for as good as Katherine is at math, basketball and singing, she wants to get better at her phone. To be one of the girls who knows what to post, how to caption it, when to like, what to comment.

Katherine doesn’t need magazines or billboards to see computer-perfect women. They’re right on her phone, all the time, in between photos of her normal-looking friends. There’s Aisha, there’s Kendall Jenner’s butt. There’s Olivia, there’s YouTube star Jenna Marbles in lingerie.

The whole world is at her fingertips and has been for years. This, Katherine offers as a theory one day, is why she doesn’t feel like she’s 13 years old at all. She’s probably, like, 16.

“I don’t feel like a child anymore” she says. “I’m not doing anything childish. At the end of sixth grade” — when all her friends got phones and downloaded Snapchat, Instagram and Twitter — “I just stopped doing everything I normally did. Playing games at recess, playing with toys, all of it, done.”

Her scooter sat in the garage, covered in dust. Her stuffed animals were passed down to Lila. The wooden playground in the back yard stood empty. She kept her skateboard with neon yellow wheels, because riding it is still cool to her friends.

On the morning of her 14th birthday, Katherine wakes up to an alarm ringing on her phone. It’s 6:30 a.m. She rolls over and shuts it off in the dark. Her grandparents, here to celebrate the end of her first year of teenagehood, are sleeping in the guest room down the hall. She can hear the dogs shuffling across the hardwood downstairs, waiting to be fed. Propping herself up on her peace-sign-covered pillow, she opens Instagram. Later, Lila will give her a Starbucks gift card. Her dad will bring doughnuts to her class. Her grandparents will take her to the Melting Pot for dinner. But first, her friends will decide whether to post pictures of Katherine for her birthday. Whether they like her enough to put a picture of her on their page. Those pictures, if they come, will get likes and maybe tbhs. They should be posted in the morning, any minute now. She scrolls past a friend posing in a bikini on the beach. Then a picture posted by Kendall Jenner. A selfie with coffee. A basketball Vine. A selfie with a girl’s tongue out. She scrolls, she waits. For that little notification box to appear.

For instance, we might choose a different metaphor—like, say, the traffic system. Sounds ridiculous? No more so than the market metaphor. After all, we already talk about one important aspect of economic life in terms of traffic: online activity. We could describe it in market terms (the market demands Trump memes!), but we use a different metaphor, because it’s just intuitively more suitable. That last Trump meme is generating a lot of traffic. Redirect your attention as required.

We don’t know much about markets, because we don’t deal with them very often. But most of us know plenty about traffic systems: drivers will know the frustration of trying to turn left onto a major road, of ceaseless, pointless lane-switching on a stalled rush-hour freeway, but also the joys of clear highways.

We know the traffic system because, whether we like it or not, we are always involved in it, from birth

As of birth, Jean is in the economy—even if s/he rarely goes to a market. You can’t not be an economic actor; you can’t not be part of the transport system.

Consider also the composition of the traffic system and the economy. A market, whatever else it is, is always essentially the same thing: a place where people can come together to buy and sell things. We could set up a market right now, with a few fences and a sign announcing that people could buy and sell. We don’t even really need the fences. A traffic system, however, is far more complex. To begin with, the system includes publicly and privately run elements: most cars are privately owned, as are most airlines

If we don’t evaluate traffic systems based on their size, or their growth, how do we evaluate them? Mostly, by how well they help people get where they want to go. The market metaphor encourages us to think that all economic activity is motivated by the search for profit, and pursued in the same fashion everywhere. In a market, everyone’s desires are perfectly interchangeable. But, while everybody engages in the transport system, we have no difficulty remembering that we all want to go to different places, in different ways, at different times, at different speeds, for different reasons

Deciding how to improve the traffic system, how to expand people’s opportunities, is obviously a question of resource allocation and prioritization on a scale that private individuals—even traders—cannot influence on their own. That’s why government have not historically trusted the “magic of the markets” to produce better opportunities for transport. We intuitively understand that these decisions are made at the level of mass society and public policy. And, whether you like it or not, this is true for decisions about the economy as well.

Thinking of the economy in terms of the market—a featureless plane, with no entry or exit costs, little need for regulation, and equal opportunity for all—obscures this basic insight. And this underlying misconception creates a lot of problems: we’ve fetishized economic growth, we’ve come to distrust government regulation, and we imagine that the inequalities in our country, and our world, are natural or justified. If we imagine the economy otherwise—as a traffic system, for example—we see more clearly how the economy actually works.

We see that our economic life looks a lot less like going to “market” for fun and profit than it does sitting in traffic on our morning commute, hoping against hope that we’ll get where we want to go, and on time.

The more screen time, the more revenue.

The goal of Facebook Inc., Alphabet Inc.’s Google, Snap Inc. and their peers is to create or host captivating experiences that keep users glued to their screens, whether for Instagram, YouTube, Snapchat or Facebook

Snapchat users 25 and younger, for example, were spending 40 minutes a day on the app, Chief Executive Evan Spiegel said in August. Alphabet boasted to investors recently that YouTube’s 1.5 billion users were spending an average 60 minutes a day on mobile.

Facebook’s stock slid 4.5% to close at $179 Friday after CEO Mark Zuckerberg announced plans Thursday to overhaul the Facebook news feed in a way that could reduce the time users spend.

Tech companies are working to instill viewing habits earlier than ever. The number of users of YouTube Kids is soaring. Facebook recently launched Messenger Kids, a messaging app for children as young as 6.

Ms. Ho’s 16-year-old son, Brian is an Eagle Scout and chorister, who at times finds it hard to break away from online videogames, even at 3 a.m. The teen recently told his mother he thinks he is addicted. Ms. Ho’s daughter, Samantha, 14, also is glued to her device, in conversations with friends.

“You think you’re buying a piece of technology,” Ms. Shepardson said. “Now it’s like oxygen to her.”

Psychologists say social media creates anxiety among children when they are away from their phones—what they call “fear of missing out,” whether on social plans, conversations or damaging gossip teens worry could be about themselves.

About half the teens in a survey of 620 families in 2016 said they felt addicted to their smartphones. Nearly 80% said they checked the phones more than hourly and felt the need to respond instantly to messages

Children set up Instagram accounts under pseudonyms that friends but not parents recognize. Some teens keep several of these so-called Finsta accounts without their parents knowing.

An app called Secret Calculator looks and works like an iPhone calculator but doubles as a private vault to hide files, photos and videos.

Mr. Zuckerberg told investors late last year that Facebook planned to boost video offerings, noting that live video generates 10 times as many user interactions. Netflix Inc. chief executive Reed Hastings, said in April about the addictiveness of its shows that the company was “competing with sleep on the margins.”

Keeping children away from disturbing content, though, is easier than keeping them off their phones.

About 16% of the nation’s high-school students were bullied online in 2015, according to the U.S. Centers for Disease Control and Prevention. Children who are cyberbullied are three times more likely to contemplate suicide

Smartphones “bring the outside in,” said Ms. Ahn, whose husband works for a major tech company. “We want the family to be the center of gravity.”

To have this conversation, consider saying: “If people within a group want to claim ownership of a word that has been used to hurt them, that’s their call, even if not everyone else in that group agrees with their decision. But if you’re not in the group, the word is definitely not yours to use.”

Not all girls and women believe that it is empowering to playfully refer to one another as bitches. Similarly, not all African-Americans share the same view on the use of the “N-word.” But its regular use in popular songs (mostly, but not entirely by black artists) has left a lot of kids who are not black wondering if they are free to use the word, too.
