A Million First Dates - Dan Slater - The Atlantic - 0 views

  • The positive aspects of online dating are clear: the Internet makes it easier for single people to meet other single people with whom they might be compatible, raising the bar for what they consider a good relationship. But what if online dating makes it too easy to meet someone new? What if it raises the bar for a good relationship too high? What if the prospect of finding an ever-more-compatible mate with the click of a mouse means a future of relationship instability, in which we keep chasing the elusive rabbit around the dating track?
  • the rise of online dating will mean an overall decrease in commitment.
  • I often wonder whether matching you up with great people is getting so efficient, and the process so enjoyable, that marriage will become obsolete.”
  • ...5 more annotations...
  • “Historically,” says Greg Blatt, the CEO of Match.com’s parent company, “relationships have been billed as ‘hard’ because, historically, commitment has been the goal. You could say online dating is simply changing people’s ideas about whether commitment itself is a life value.” Mate scarcity also plays an important role in people’s relationship decisions. “Look, if I lived in Iowa, I’d be married with four children by now,” says Blatt, a 40‑something bachelor in Manhattan. “That’s just how it is.”
  • “I think divorce rates will increase as life in general becomes more real-time,” says Niccolò Formai, the head of social-media marketing at Badoo, a meeting-and-dating app with about 25 million active users worldwide. “Think about the evolution of other kinds of content on the Web—stock quotes, news. The goal has always been to make it faster. The same thing will happen with meeting. It’s exhilarating to connect with new people, not to mention beneficial for reasons having nothing to do with romance. You network for a job. You find a flatmate. Over time you’ll expect that constant flow. People always said that the need for stability would keep commitment alive. But that thinking was based on a world in which you didn’t meet that many people.”
  • “You could say online dating allows people to get into relationships, learn things, and ultimately make a better selection,” says Gonzaga. “But you could also easily see a world in which online dating leads to people leaving relationships the moment they’re not working—an overall weakening of commitment.”
  • Explaining the mentality of a typical dating-site executive, Justin Parfitt, a dating entrepreneur based in San Francisco, puts the matter bluntly: “They’re thinking, Let’s keep this fucker coming back to the site as often as we can.” For instance, long after their accounts become inactive on Match.com and some other sites, lapsed users receive notifications informing them that wonderful people are browsing their profiles and are eager to chat. “Most of our users are return customers,” says Match.com’s Blatt.
  • The market is hugely more efficient … People expect to—and this will be increasingly the case over time—access people anywhere, anytime, based on complex search requests … Such a feeling of access affects our pursuit of love … the whole world (versus, say, the city we live in) will, increasingly, feel like the market for our partner(s). Our pickiness will probably increase.” “Above all, Internet dating has helped people of all ages realize that there’s no need to settle for a mediocre relationship.”

Facebook Has 50 Minutes of Your Time Each Day. It Wants More. - The New York Times - 0 views

  • Fifty minutes.That’s the average amount of time, the company said, that users spend each day on its Facebook, Instagram and Messenger platforms
  • there are only 24 hours in a day, and the average person sleeps for 8.8 of them. That means more than one-sixteenth of the average user’s waking time is spent on Facebook.
  • That’s more than any other leisure activity surveyed by the Bureau of Labor Statistics, with the exception of watching television programs and movies (an average per day of 2.8 hours)
  • ...19 more annotations...
  • It’s more time than people spend reading (19 minutes); participating in sports or exercise (17 minutes); or social events (four minutes). It’s almost as much time as people spend eating and drinking (1.07 hours).
  • the average time people spend on Facebook has gone up — from around 40 minutes in 2014 — even as the number of monthly active users has surged. And that’s just the average. Some users must be spending many hours a day on the site,
  • time has become the holy grail of digital media.
  • Time is the best measure of engagement, and engagement correlates with advertising effectiveness. Time also increases the supply of impressions that Facebook can sell, which brings in more revenue (a 52 percent increase last quarter to $5.4 billion).
  • And time enables Facebook to learn more about its users — their habits and interests — and thus better target its ads. The result is a powerful network effect that competitors will be hard pressed to match.
  • the only one that comes close is Alphabet’s YouTube, where users spent an average of 17 minutes a day on the site. That’s less than half the 35 minutes a day users spent on Facebook
  • ComScore reported that television viewing (both live and recorded) dropped 2 percent last year, and it said younger viewers in particular are abandoning traditional live television. People ages 18-34 spent just 47 percent of their viewing time on television screens, and 40 percent on mobile devices.
  • People spending the most time on Facebook also tend to fall into the prized 18-to-34 demographic sought by advertisers.
  • “You hear a narrative that young people are fleeing Facebook. The data show that’s just not true. Younger users have a wider appetite for social media, and they spend a lot of time on multiple networks. But they spend more time on Facebook by a wide margin.”
  • What aren’t Facebook users doing during the 50 minutes they spend there? Is it possibly interfering with work (and productivity), or, in the case of young people, studying and reading?
  • While the Bureau of Labor Statistics surveys nearly every conceivable time-occupying activity (even fencing and spelunking), it doesn’t specifically tally the time spent on social media, both because the activity may have multiple purposes — both work and leisure — and because people often do it at the same time they are ostensibly engaged in other activities
  • The closest category would be “computer use for leisure,” which has grown from eight minutes in 2006, when the bureau began collecting the data, to 14 minutes in 2014, the most recent survey. Or perhaps it would be “socializing and communicating with others,” which slipped from 40 minutes to 38 minutes.
  • But time spent on most leisure activities hasn’t changed much in those eight years of the bureau’s surveys. Time spent reading dropped from an average of 22 minutes to 19 minutes. Watching television and movies increased from 2.57 hours to 2.8. Average time spent working declined from 3.4 hours to 3.25. (Those hours seem low because much of the population, which includes both young people and the elderly, does not work.)
  • The bureau’s numbers, since they cover the entire population, may be too broad to capture important shifts among important demographic groups
  • Users spent an average of nine minutes on all of Yahoo’s sites, two minutes on LinkedIn and just one minute on Twitter
  • Among those 55 and older, 70 percent of their viewing time was on television, according to comScore. So among young people, much social media time may be coming at the expense of traditional television.
  • comScore’s data suggests that people are spending on average just six to seven minutes a day using social media on their work computers. “I don’t think Facebook is displacing other activity,” he said. “People use it during downtime during the course of their day, in the elevator, or while commuting, or waiting.
  • Facebook, naturally, is busy cooking up ways to get us to spend even more time on the platform
  • A crucial initiative is improving its News Feed, tailoring it more precisely to the needs and interests of its users, based on how long people spend reading particular posts. For people who demonstrate a preference for video, more video will appear near the top of their news feed. The more time people spend on Facebook, the more data they will generate about themselves, and the better the company will get at the task.

Chris Hayes Has Arrived With 'Up' - NYTimes.com - 0 views

  • In less than a year on television (and with a chirpy voice, a weakness for gesticulation and a tendency to drop honors-thesis words like “signifier” into casual conversation), Mr. Hayes has established himself as Generation Y’s wonk prince of the morning political talk-show circuit.
  • “He is never doctrinaire,” Mr. Leo said in an interview. Both punk fans and “Up” fans are “suspicious of any authority,” he said, and appreciate that Mr. Hayes “is always willing to challenge his own assumptions, and the received wisdom on both sides of the aisle.”
  • Social media, in fact, have played an unusually important role in driving traffic to the program, an MSNBC spokeswoman said. About 45 percent of the visitors to the program’s Web site, which contains complete episodes, linked through sites like Facebook and Twitter. In April, those users spent an average of 51 minutes on the site each visit.

  • “Up” comes off as a rebuke to traditional cable shout-fests like CNN’s late “Crossfire.” Thanks to its early weekend time slot, the program has the freedom to unwind over two hours each Saturday and Sunday. Guests are encouraged to go deep into the issues of the week, and not try to score cheap-shot points to win the debate.
  • “The first and foremost important rule of the show: we’re not on television — no talking points, no sound bites,” he said, his hair still a bed-head tangle and his suit collar askew. “We have a lot of time for actual conversation. So actually listen, actually respond.”
  • An hour later, as the cameras rolled, Mr. Hayes and his guests waded thigh-deep into an analysis of private equity and whether it is bad for the economy. At a table of wonks, Mr. Hayes, who studied the philosophy of mathematics at Brown, came off as the wonkiest as he deconstructed the budgetary implications of tax arbitrage. Opinions were varied and passionate, but there was no sniping, no partisan grandstanding.
  • “I like t

  • Since Dec. 26, it has been No. 1 on average in its Sunday time slot on cable news channels among viewers ages 18 to 34, according to Nielsen figures provided by the network.
  • Ms. Maddow said on her program that “Up” was “the best news show on TV, including this one.” “Chris is the antidote to the anti-intellectual posing that has characterized the last decade in cable news,”
  • “No one else in cable is even trying long-form, off-the-news-cycle dives like him — let alone succeeding at them as he is. He’s giving the network Sunday shows a run for their money.”
  • As a student at Hunter College High School in Manhattan, he aspired to write. “My dream when I was 14,” he said, “was someday I could have a David Levine caricature of me in The New York Review of Books.”

The Washington Monthly - The Magazine - The Information Sage - 0 views

  • PowerPoint, a software program that Tufte says is constricting and obfuscating and “turns information into a sales pitch.”
  • Tufte dissected NASA’s PowerPoint slides on his Web site, showing that the program didn’t allow engineers to write in scientific notation and replaced complex quantitative measurement with imprecise words like “significant.” He then published a twenty-eight-page essay called “The Cognitive Style of PowerPoint,” in which he analyzed hundreds of existing PowerPoint slides and showed that the statistical graphics used in PowerPoint presentations show an average of twelve numbers each, which, in Tufte’s analysis, ranks it below every major world publication except for Pravda. The low information density of PowerPoint is “approaching dementia,” he wrote.
  • the reliance on PowerPoint often means that battle orders are rendered in incomplete, often unclear sentences and maps are squashed and stripped of meaningful detail, leaving essential battlefield questions of geography dangerously unclear. The details are classified, but Hammes told me that he has seen war plans for the Korean peninsula prepared in PowerPoint in which massive terrain issues were completely glossed over. On the whole, Hammes told me, the rise of PowerPoint in the military has made the decision-making process less intellectually active. And Tufte, he added, “is the master on this whole thing.”
  • ...2 more annotations...
  • Nate Silver, who runs the political Web site FiveThirtyEight, now part of the New York Times, uses many of Tufte’s maxims in the site’s design. Silver told me that he tries to keep the “data-ink” ratio of his current site very high, meaning most of the pixels on the screen show actual numbers or data points; he also thinks of the site’s design in terms of “small multiples,” another Tufte neologism that refers to a series of related numbers that reveal subtle differences over time. “Tufte treats data like good writing,” he said. “You have a certain thought—how clearly and beautifully are you conveying it?”
  • Good design, then, is not about making dull numbers somehow become magically exhilarating, it is about picking the right numbers in the first place. “It’s about data that matters to you,”

Dating Study: At What Age Are Men, Women Most Desirable? - The Atlantic - 0 views

  • “Three-quarters, or more, of people are dating aspirationally,” she says. And according to a new study, users of online-dating sites spend most of their time trying to contact people “out of their league.”In fact, most online-dating users tend to message people exactly 25 percent more desirable than they are.
  • “There’s so much folk wisdom about dating and courtship, and very little scientific evidence,” she told me recently. “My research comes out of realizing that with these large-scale data sets, we can shed light on a lot of these old dating aphorisms
  • Bruch and her colleagues analyzed thousands of messages exchanged on a “popular, free online-dating service” between more than 186,000 straight men and women. They looked only at four metro areas—New York, Boston, Chicago, and Seattle—and only at messages from January 2014.
  • ...19 more annotations...
  • imagine that you are a very desirable user. Your specific desirability rank would have been generated by two figures: whether other desirable people contacted you, and whether other desirable people responded when you contacted them. If you contacted a much less desirable person, their desirability score would rise; if they contacted you and you replied, then your score would fall.
  • The team had to analyze both first messages and first replies, because, well, men usually make the first move. “A defining feature of heterosexual online dating is that, in the vast majority of cases, it is men who establish the first contact—more than 80 percent of first messages are from men in our data set,” the study says. But “women reply very selectively to the messages they receive from men—their average reply rate is less than 20 percent—so women’s replies … can give us significant insight about who they are interested in.”
  • It found that—insofar as dating “leagues” are not different tiers of hotness, but a single ascending hierarchy of desirability—then they do seem to exist in the data. But people do not seem universally locked into them—and they can occasionally find success escaping from theirs.
  • “I mean, everybody knows—and as a sociologist, it’s been shown—that older women have a harder time in the dating market. But I hadn’t expected to see their desirability drop off from the time they’re 18 to the time they’re 65,”
  • Across the four cities and the thousands of users, consistent patterns around age, race, and education level emerge. White men and Asian women are consistently more desired than other users, while black women rank anomalously lower.
  • “what we are seeing is overwhelmingly the effect of white preferences,” she cautioned. “This site is predominantly white, 70 percent white. If this was a site that was 20 percent white, we may see a totally different desirability hierarchy.”
  • And Bruch emphasized that the hierarchy did not just depend on race, age, and education level: Because it is derived from user behavior, it “captures whatever traits people are responding to when they pursue partners. This will include traits like wittiness, genetic factors, or whatever else drives people to message,” she said.
  • Here are seven other not entirely happy takeaways from Bruch’s study:- In the study, men’s desirability peaks at age 50. But women’s desirability starts high at age 18 and falls throughout their lifespan.
  • The key, Bruch said, is that “persistence pays off.”“Reply rates [to the average message] are between zero percent and 10 percent,” she told me. Her advice: People should note those extremely low reply rates and send out more greetings.
  • I was also surprised to see how flat men’s desirability was over the age distribution,” she said. “For men, it peaks around age 40 or 50. Especially in New York.”
  • “New York is a special case for men,” Bruch told me. “It’s the market with the highest fraction of women. But it’s also about it being an incredibly dense market.”
  • “Seattle presents the most unfavorable dating climate for men, with as many as two men for every woman in some segments,” the study says
  • Across all four cities, men and women generally tended to send longer messages to people who were more desirable than them. Women, especially, deployed this strategy.
  • But the only place it paid off—and the only people for whom it worked with statistically significant success—were men in Seattle. The longest messages in the study were sent by Seattle men, the study says,“and only Seattle men experience a payoff to writing longer messages.”
  • A more educated man is almost always more desirable, on average: Men with postgraduate degrees outperform men with bachelor’s degrees; men with bachelor’s degrees beat high-school graduates.
  • “But for women, an undergraduate degree is most desirable,” the study says. “Postgraduate education is associated with decreased desirability among women.
  • men tended to use less positive language when messaging more desirable women. They may have stumbled upon this strategy through trial and error because “in all four cities, men experience slightly lower reply rates when they write more positively worded messages.”
  • “The most common behavior for both men and women is to contact members of the opposite sex who on average have roughly the same ranking as themselves,
  • “The most popular individual in our four cities, a 30-year-old woman living in New York, received 1504 messages during the period of observation,” the study says. This is “equivalent to one message every 30 min, day and night, for the entire month.”

Have Smartphones Destroyed a Generation? - The Atlantic - 0 views

  • She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”
  • The arrival of the smartphone has radically changed every aspect of teenagers’ lives, from the nature of their social interactions to their mental health. These changes have affected young people in every corner of the nation and in every type of household
  • Around 2012, I noticed abrupt shifts in teen behaviors and emotional states. The gentle slopes of the line graphs became steep mountains and sheer cliffs, and many of the distinctive characteristics of the Millennial generation began to disappear. In all my analyses of generational data—some reaching back to the 1930s—I had never seen anything like it.
  • ...54 more annotations...
  • the trends persisted, across several years and a series of national surveys. The changes weren’t just in degree, but in kind.
  • The biggest difference between the Millennials and their predecessors was in how they viewed the world; teens today differ from the Millennials not just in their views but in how they spend their time. The experiences they have every day are radically different from those of the generation that came of age just a few years before them.
  • it was exactly the moment when the proportion of Americans who owned a smartphone surpassed 50 percent.
  • theirs is a generation shaped by the smartphone and by the concomitant rise of social media. I call them iGen
  • Born between 1995 and 2012, members of this generation are growing up with smartphones, have an Instagram account before they start high school, and do not remember a time before the internet.
  • iGen’s oldest members were early adolescents when the iPhone was introduced, in 2007, and high-school students when the iPad entered the scene, in 2010. A 2017 survey of more than 5,000 American teens found that three out of four owned an iPhone.
  • . I had grown accustomed to line graphs of trends that looked like modest hills and valleys. Then I began studying Athena’s generation.
  • More comfortable in their bedrooms than in a car or at a party, today’s teens are physically safer than teens have ever been. They’re markedly less likely to get into a car accident and, having less of a taste for alcohol than their predecessors, are less susceptible to drinking’s attendant ills.
  • Psychologically, however, they are more vulnerable than Millennials were: Rates of teen depression and suicide have skyrocketed since 2011. It’s not an exaggeration to describe iGen as being on the brink of the worst mental-health crisis in decades. Much of this deterioration can be traced to their phones.
  • the twin rise of the smartphone and social media has caused an earthquake of a magnitude we’ve not seen in a very long time, if ever. There is compelling evidence that the devices we’ve placed in young people’s hands are having profound effects on their lives—and making them seriously unhappy.
  • But the allure of independence, so powerful to previous generations, holds less sway over today’s teens, who are less likely to leave the house without their parents. The shift is stunning: 12th-graders in 2015 were going out less often than eighth-graders did as recently as 2009.
  • Today’s teens are also less likely to date. The initial stage of courtship, which Gen Xers called “liking” (as in “Ooh, he likes you!”), kids now call “talking”—an ironic choice for a generation that prefers texting to actual conversation. After two teens have “talked” for a while, they might start dating.
  • only about 56 percent of high-school seniors in 2015 went out on dates; for Boomers and Gen Xers, the number was about 85 percent.
  • The decline in dating tracks with a decline in sexual activity. The drop is the sharpest for ninth-graders, among whom the number of sexually active teens has been cut by almost 40 percent since 1991. The average teen now has had sex for the first time by the spring of 11th grade, a full year later than the average Gen Xer
  • The teen birth rate hit an all-time low in 2016, down 67 percent since its modern peak, in 1991.
  • Nearly all Boomer high-school students had their driver’s license by the spring of their senior year; more than one in four teens today still lack one at the end of high school.
  • In conversation after conversation, teens described getting their license as something to be nagged into by their parents—a notion that would have been unthinkable to previous generations.
  • In the late 1970s, 77 percent of high-school seniors worked for pay during the school year; by the mid-2010s, only 55 percent did. The number of eighth-graders who work for pay has been cut in half.
  • Beginning with Millennials and continuing with iGen, adolescence is contracting again—but only because its onset is being delayed. Across a range of behaviors—drinking, dating, spending time unsupervised— 18-year-olds now act more like 15-year-olds used to, and 15-year-olds more like 13-year-olds. Childhood now stretches well into high school.
  • In an information economy that rewards higher education more than early work history, parents may be inclined to encourage their kids to stay home and study rather than to get a part-time job. Teens, in turn, seem to be content with this homebody arrangement—not because they’re so studious, but because their social life is lived on their phone. They don’t need to leave home to spend time with their friends.
  • eighth-, 10th-, and 12th-graders in the 2010s actually spend less time on homework than Gen X teens did in the early 1990s.
  • The time that seniors spend on activities such as student clubs and sports and exercise has changed little in recent years. Combined with the decline in working for pay, this means iGen teens have more leisure time than Gen X teens did, not less.
  • So what are they doing with all that time? They are on their phone, in their room, alone and often distressed.
  • despite spending far more time under the same roof as their parents, today’s teens can hardly be said to be closer to their mothers and fathers than their predecessors were. “I’ve seen my friends with their families—they don’t talk to them,” Athena told me. “They just say ‘Okay, okay, whatever’ while they’re on their phones. They don’t pay attention to their family.” Like her peers, Athena is an expert at tuning out her parents so she can focus on her phone.
  • The number of teens who get together with their friends nearly every day dropped by more than 40 percent from 2000 to 2015; the decline has been especially steep recently.
  • Eighth-graders who are heavy users of social media increase their risk of depression by 27 percent, while those who play sports, go to religious services, or even do homework more than the average teen cut their risk significantly.
  • The roller rink, the basketball court, the town pool, the local necking spot—they’ve all been replaced by virtual spaces accessed through apps and the web.
  • The results could not be clearer: Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy.
  • There’s not a single exception. All screen activities are linked to less happiness, and all nonscreen activities are linked to more happiness
  • Eighth-graders who spend 10 or more hours a week on social media are 56 percent more likely to say they’re unhappy than those who devote less time to social media
  • If you were going to give advice for a happy adolescence based on this survey, it would be straightforward: Put down the phone, turn off the laptop, and do something—anything—that does not involve a screen
  • Social-networking sites like Facebook promise to connect us to friends. But the portrait of iGen teens emerging from the data is one of a lonely, dislocated generation. Teens who visit social-networking sites every day but see their friends in person less frequently are the most likely to agree with the statements “A lot of times I feel lonely,” “I often feel left out of things,” and “I often wish I had more good friends.” Teens’ feelings of loneliness spiked in 2013 and have remained high since.
  • This doesn’t always mean that, on an individual level, kids who spend more time online are lonelier than kids who spend less time online.
  • Teens who spend more time on social media also spend more time with their friends in person, on average—highly social teens are more social in both venues, and less social teens are less so.
  • The more time teens spend looking at screens, the more likely they are to report symptoms of depression.
  • It’s not only a matter of fewer kids partying; fewer kids are spending time simply hanging out
  • Teens who spend three hours a day or more on electronic devices are 35 percent more likely to have a risk factor for suicide, such as making a suicide plan. (That’s much more than the risk related to, say, watching TV.)
  • Since 2007, the homicide rate among teens has declined, but the suicide rate has increased. As teens have started spending less time together, they have become less likely to kill one another, and more likely to kill themselves. In 2011, for the first time in 24 years, the teen suicide rate was higher than the teen homicide rate.
  • For all their power to link kids day and night, social media also exacerbate the age-old teen concern about being left out.
  • Today’s teens may go to fewer parties and spend less time together in person, but when they do congregate, they document their hangouts relentlessly—on Snapchat, Instagram, Facebook. Those not invited to come along are keenly aware of it. Accordingly, the number of teens who feel left out has reached all-time highs across age groups.
  • Forty-eight percent more girls said they often felt left out in 2015 than in 2010, compared with 27 percent more boys. Girls use social media more often, giving them additional opportunities to feel excluded and lonely when they see their friends or classmates getting together without them.
  • Social media levy a psychic tax on the teen doing the posting as well, as she anxiously awaits the affirmation of comments and likes. When Athena posts pictures to Instagram, she told me, “I’m nervous about what people think and are going to say. It sometimes bugs me when I don’t get a certain amount of likes on a picture.”
  • Girls have also borne the brunt of the rise in depressive symptoms among today’s teens. Boys’ depressive symptoms increased by 21 percent from 2012 to 2015, while girls’ increased by 50 percent—more than twice as much
  • The rise in suicide, too, is more pronounced among girls. Although the rate increased for both sexes, three times as many 12-to-14-year-old girls killed themselves in 2015 as in 2007, compared with twice as many boys
  • Social media give middle- and high-school girls a platform on which to carry out the style of aggression they favor, ostracizing and excluding other girls around the clock.
  • I asked my undergraduate students at San Diego State University what they do with their phone while they sleep. Their answers were a profile in obsession. Nearly all slept with their phone, putting it under their pillow, on the mattress, or at the very least within arm’s reach of the bed. They checked social media right before they went to sleep, and reached for their phone as soon as they woke up in the morning
  • the smartphone is cutting into teens’ sleep: Many now sleep less than seven hours most nights. Sleep experts say that teens should get about nine hours of sleep a night; a teen who is getting less than seven hours a night is significantly sleep deprived
  • Fifty-seven percent more teens were sleep deprived in 2015 than in 1991. In just the four years from 2012 to 2015, 22 percent more teens failed to get seven hours of sleep.
  • Two national surveys show that teens who spend three or more hours a day on electronic devices are 28 percent more likely to get less than seven hours of sleep than those who spend fewer than three hours, and teens who visit social-media sites every day are 19 percent more likely to be sleep deprived.
  • Teens who read books and magazines more often than the average are actually slightly less likely to be sleep deprived—either reading lulls them to sleep, or they can put the book down at bedtime.
  • Sleep deprivation is linked to myriad issues, including compromised thinking and reasoning, susceptibility to illness, weight gain, and high blood pressure. It also affects mood: People who don’t sleep enough are prone to depression and anxiety.
  • correlations between depression and smartphone use are strong enough to suggest that more parents should be telling their kids to put down their phone.
  • What’s at stake isn’t just how kids experience adolescence. The constant presence of smartphones is likely to affect them well into adulthood. Among people who suffer an episode of depression, at least half become depressed again later in life. Adolescence is a key time for developing social skills; as teens spend less time with their friends face-to-face, they have fewer opportunities to practice them
  • Significant effects on both mental health and sleep time appear after two or more hours a day on electronic devices. The average teen spends about two and a half hours a day on electronic devices. Some mild boundary-setting could keep kids from falling into harmful habits.

6 Ways Social Media Affects Our Mental Health - 0 views

  • But possibly as concerning is the thing that we often do while we're sitting: Mindlessly scrolling through our social media feeds when we have a few spare minutes (or for some, hours)
  • It’s addictive
  • Experts have not been in total agreement on whether internet addiction is a real thing, let alone social media addiction, but there’s some good evidence that both may exist.
  • ...14 more annotations...
  • And studies have confirmed that people tend to undergo a kind of withdrawal: A study a few years ago from Swansea University found that people experienced the psychological symptoms of withdrawal when they stopped using (this went for all internet use, not just social media).
  • It triggers more sadness, less well-being
  • The more we use social media, the less happy we seem to be. One study a few years ago found that Facebook use was linked to both less moment-to-moment happiness and less life satisfaction—the more people used Facebook in a day, the more these two variables dropped off
  • In fact, another study found that social media use is linked to greater feelings of social isolation.
  • Comparing our lives with others is mentally unhealthy
  • One study looked at how we make comparisons to others posts, in “upward” or “downward” directions—that is, feeling that we’re either better or worse off than our friends.
  • It can lead to jealousy—and a vicious cycle
  • Studies have certainly shown that social media use triggers feelings of jealousy. The authors of one study, looking at jealousy and other negative feelings while using Facebook, wrote that “This magnitude of envy incidents taking place on FB alone is astounding, providing evidence that FB offers a breeding ground for invidious feelings."
  • We get caught in the delusion of thinking it will help
  • Part of the unhealthy cycle is that we keep coming back to social media, even though it doesn’t make us feel very good.
  • This is probably because of what’s known as a forecasting error: Like a drug, we think getting a fix will help, but it actually makes us feel worse, which comes down to an error in our ability to predict our own response.
  • More friends on social doesn’t mean you’re more social
  • A couple of years ago, a study found that more friends on social media doesn’t necessarily mean you have a better social life—there seems to be a cap on the number of friends a person’s brain can handle, and it takes actual social interaction (not virtual) to keep up these friendships
  • All of this is not to say that there’s no benefit to social media—obviously it keeps us connected across great distances, and helps us find people we’d lost touch with years ago

In Some Countries, Facebook's Fiddling Has Magnified Fake News - The New York Times - 0 views

  • In Some Countries, Facebook’s Fiddling Has Magnified Fake News
  • SAN FRANCISCO — One morning in October, the editors of Página Siete, Bolivia’s third-largest news site, noticed that traffic to their outlet coming from Facebook was plummeting.The publication had recently been hit by cyberattacks, and editors feared it was being targeted by hackers loyal to the government of President Evo Morales.
  • But it wasn’t the government’s fault. It was Facebook’s. The Silicon Valley company was testing a new version of its hugely popular News Feed, peeling off professional news sites from what people normally see and relegating them to a new section of Facebook called Explore.
  • ...4 more annotations...
  • Facebook said these News Feed modifications were not identical to those introduced last fall in six countries through its Explore program, but both alterations favor posts from friends and family over professional news sites. And what happened in those countries illustrates the unintended consequences of such a change in an online service that now has a global reach of more than two billion people every month.
  • The fabricated story circulated so widely that the local police issued a statement saying it wasn’t true. But when the police went to issue the warning on Facebook, they found that the message — unlike the fake news story they meant to combat — could no longer appear on News Feed because it came from an official account.Facebook explained its goals for the Explore program in Slovakia, Sri Lanka, Cambodia, Bolivia, Guatemala and Serbia in a blog post in October. “The goal of this test is to understand if people prefer to have separate places for personal and public content,” wrote Adam Mosseri, head of Facebook’s News Feed. “There is no current plan to roll this out beyond these test countries.”
  • The loss of visitors from Facebook was readily apparent in October, and Mr. Huallpa could communicate with Facebook only through a customer service form letter. He received an automatic reply in return.

Opinion | Barack Obama's smart way to change the disinformation debate - The Washington... - 0 views

  • The former president spoke at Stanford University on April 21 to lay out his vision for fighting disinformation on the Internet. His focus on the subject is fitting; the dusk of his administration marked a turning point from techno-optimism to pessimism after election interference revealed how easily malicious actors could exploit the free flow of information.
  • His diagnosis is on target. The Internet has given us access to more people, more opportunities and more knowledge
  • This has helped activists drum up attention for overlooked causes. It has also enabled the nation’s adversaries to play on our preexisting prejudices and divisions to sow discord
  • ...5 more annotations...
  • Mr. Obama starts where most lawmakers are stuck: Section 230 of the Communications Decency Act, which gives platforms immunity from legal liability for most third-party posts. He suggested a “higher standard of care” for ads than for so-called organic content that everyday users post. This would strike a sensible balance between eviscerating Section 230, making sites accountable for everything they host, and doing nothing.
  • On top of that, “an instant, 24/7 global information stream,” from which audiences can pick and choose material that confirms their biases, has deepened the social divides that bad actors seek to exploit.
  • Mr. Obama identified another problem with the Section 230 talk: homing in on what material platforms do and don’t take down risks missing how the “very design” of these sites privileges polarizing, inflammatory posts.
  • With this, Mr. Obama adds something vital to the mainstream debate over social media regulation, shifting attention away from a debate about whack-a-mole content removal and toward the sites’ underlying structures. His specific suggestions, while fuzzy, also have promise — from slowing down viral material to imposing transparency obligations that would subject social media companies’ algorithms to scrutiny from researchers and regulators.
  • Mr. Obama calls this “democratic oversight.” But the material companies reveal could be highly technical. Ideally, it would get translated into layman’s terms so that everyday people, too, can understand how decisions so significant in their daily lives and the life of the country are made.

What Do We Lose If We Lose Twitter? - The Atlantic - 0 views

  • At its best, Twitter can still provide that magic of discovering a niche expert or elevating a necessary, insurgent voice, but there is far more noise than signal. Plenty of those overenthusiastic voices, brilliant thinkers, and influential accounts have burned out on culture-warring, or have been harassed off the site or into lurking.

At a moment when people were terrified and looking for any information at all, Twitter seemed to offer a steady stream of knowledgeable, diligent experts.

Football and racist language: Reclaiming the Y-word | The Economist - 0 views

  • Game theory Sports Previous Next Latest Game theory Latest from all our blogs Football and racist language Reclaiming the Y-word Nov 9th 2012, 16:28 by B.R. ENGLISH football grounds in the 1980s were not pleasant places. Fans were squeezed into caged terraces which were often left open to the elements. Hooliganism was rife and the country was in a state of moral panic as lurid images of fighting youths became a fixture on news bulletins. Margaret Thatcher, the prime minister, convened a "war cabinet". Ken Bates, the chairman of Chelsea football club, suggested electrifying the fences in the stadiums to keep the warring factions apart. By the end of the decade English football reached its nadir. In 1985, 39 Italian football fans had been killed in Heysel, Belgium after a riot by Liverpool supporters. In 1989, Liverpool supporters themselves were the victims as 96 lost their lives at Hillsborough as a result of incompetent policing.Some time toward the beginning of that decade, aged around ten, your correspondent was taken to his first away game by his father, a fanatical supporter of Tottenham Hotspur. The game was a derby with Chelsea, a bitter London rival. Chelsea's fans were among the game’s most notorious. Many were skinheads; foot soldiers of extreme right-wing parties such as the National Front and the British Movement. Tottenham, because of the area in North London in which it is situated, had a large and visible Jewish following. It did not make for a pleasant combination. At one point during the first half the hostile Chelsea crowd fell suddenly silent. Quietly at first came a hissing sound, like someone letting out gas from a canister. Before long the hissing reached crescendo. It was a terrifying sound for a small boy. But I was too young to grasp the significance. Only later was I filled in: the Chelsea fans were mimicking the sound of cyanide being released at a Nazi concentration camp. As the years wore on, the abuse towards Spurs fans became less subtle. When clubs with a large right-wing following came to Tottenham’s White Hart Lane stadium, such as Chelsea, West Ham, Leeds and Manchester United, the anti-semitism was relentless. One common song ran:Spurs are on their way to BelsenHitler's going to gas ‘em againThe Yids from TottenhamThe Yids from White Hart Lane The Y-word. It was the most relentless chant of all. Thousand of opposition fans, faces snarled, would come together in spiteful mantra: “Yiddo! Yiddo!” It was directed towards Tottenham fans and players alike. It would go on for minutes at a time, many times in a game. After a while it was so commonplace that one became immune to it. At some point during that time, something odd began to happen. Tottenham fans began to appropriate the Y-word. Gradually they began to refer to themselves as Yids. The club’s supporters started to describe themselves as the “Yid Army”. Soon the word was being chanted solely by Tottenham fans referring to themselves in a spirit of celebration and of togetherness. It had been reclaimed in much the same way that the word “nigger” was taken back by black hip-hop artists and “queer” was by gays.As a result, the word died as an insult, at least within football grounds.

Computer Algorithms Rely Increasingly on Human Helpers - NYTimes.com - 0 views

  • Although algorithms are growing ever more powerful, fast and precise, the computers themselves are literal-minded, and context and nuance often elude them. Capable as these machines are, they are not always up to deciphering the ambiguity of human language and the mystery of reasoning.
  • And so, while programming experts still write the step-by-step instructions of computer code, additional people are needed to make more subtle contributions as the work the computers do has become more involved. People evaluate, edit or correct an algorithm’s work. Or they assemble online databases of knowledge and check and verify them — creating, essentially, a crib sheet the computer can call on for a quick answer. Humans can interpret and tweak information in ways that are understandable to both computers and other humans.
  • Even at Google, where algorithms and engineers reign supreme in the company’s business and culture, the human contribution to search results is increasing. Google uses human helpers in two ways. Several months ago, it began presenting summaries of information on the right side of a search page when a user typed in the name of a well-known person or place, like “Barack Obama” or “New York City.” These summaries draw from databases of knowledge like Wikipedia, the C.I.A. World Factbook and Freebase, whose parent company, Metaweb, Google acquired in 2010. These databases are edited by humans.

  • When Google’s algorithm detects a search term for which this distilled information is available, the search engine is trained to go fetch it rather than merely present links to Web pages. “There has been a shift in our thinking,” said Scott Huffman, an engineering director in charge of search quality at Google. “A part of our resources are now more human curated.”
  • “Our engineers evolve the algorithm, and humans help us see if a suggested change is really an improvement,” Mr. Huffman said.

Write My Essay, Please! - Richard Gunderman - The Atlantic - 1 views

  • Why aren't the students who use these services crafting their own essays to begin with?
  • Here is where the real problem lies. The idea of paying someone else to do your work for you has become increasingly commonplace in our broader culture, even in the realm of writing. It is well known that many actors, athletes, politicians, and businesspeople have contracted with uncredited ghostwriters to produce their memoirs for them. There is no law against it.
  • At the same time, higher education has been transformed into an industry, another sphere of economic activity where goods and services are bought and sold. By this logic, a student who pays a fair market price for it has earned whatever grade it brings. In fact, many institutions of higher education market not the challenges provided by their course of study, but the ease with which busy students can complete it in the midst of other daily responsibilities.

If the entire course is online, why shouldn't students hire someone to enroll and complete all its requirements on their behalf? In fact, "Take-my-course.com" sites have already begun to appear.

Good reasoning needn't make you an unfeeling robot - 1 views

  • There are two brain networks, called in the literature the “Default Mode Network” and the “Task Positive Network” – and it was shown these activate in different reasoning situations, but rarely together. One network lit up when subjects were asked to reason about physical systems (including the mechanical properties of inanimate objects); the other lit up when subjects were asked to reason about social situations (including the mental states of other people).
  • Some people have jumped to bad conclusions on the basis of this evidence, claiming that it shows “analytic thinking” and “empathy” are in tension, and that when we reason carefully, we can’t see the human cost of our decisions.
  • These are all open questions where the logician, the linguist and the philosopher enter the picture, to help us understand how we can represent and reason about the world.
  •  
    This article is saying that emotion and reasoning is not in conflict. Although our brain has two distinctive system of thinking, it doesn't tension between thinking and feeling. So our emotion and our reasoning is coexisting. A good reasoning doesn't conflict with moral judgment. Good reasoning is also coming up with possibilities to consider the options to explore. However, this topic is still debatable. --Sissi (11/29/2016)

Social Media and the Devolution of Friendship: Full Essay (Pts I & II) » Cybo... - 1 views

  • social networking sites create pressure to put time and effort into tending weak ties, and how it can be impossible to keep up with them all. Personally, I also find it difficult to keep up with my strong ties. I’m a great “pick up where we left off” friend, as are most of the people closest to me (makes sense, right?). I’m decidedly sub-awesome, however, at being in constant contact with more than a few people at a time.
  • the devolution of friendship. As I explain over the course of this essay, I link the devolution of friendship to—but do not “blame” it on—the affordances of various social networking platforms, especially (but not exclusively) so-called “frictionless sharing” features.
  • I’m using the word here in the same way that people use it to talk about the devolution of health care. One example of devolution of health care is some outpatient surgeries: patients are allowed to go home after their operations, but they still require a good deal of post-operative care such as changing bandages, irrigating wounds, administering medications, etc. Whereas before these patients would stay in the hospital and nurses would perform the care-labor necessary for their recoveries, patients must now find their own caregivers (usually family members or friends; sometimes themselves) to perform free care-labor. In this context, devolution marks the shift of labor and responsibility away from the medical establishment and onto the patient; within the patient-medical establishment collaboration, the patient must now provide a greater portion of the necessary work. Similarly, in some ways, we now expect our friends to do a greater portion of the work of being friends with us.
  • ...13 more annotations...
  • Through social media, “sharing with friends” is rationalized to the point of relentless efficiency. The current apex of such rationalization is frictionless sharing: we no longer need to perform the labor of telling our individual friends about what we read online, or of copy-pasting links and emailing them to “the list,” or of clicking a button for one-step posting of links on our Facebook walls. With frictionless sharing, all we have to do is look, or listen; what we’ve read or watched or listened to is then “shared” or “scrobbled” to our Facebook, Twitter, Tumblr, or whatever other online profiles. Whether we share content actively or passively, however, we feel as though we’ve done our half of the friendship-labor by ‘pushing’ the information to our walls, streams, and tumblelogs. It’s then up to our friends to perform their halves of the friendship-labor by ‘pulling’ the information we share from those platforms.
  • We’re busy people; we like the idea of making one announcement on Facebook and being done with it, rather than having to repeat the same story over and over again to different friends individually. We also like not always having to think about which friends might like which stories or songs; we like the idea of sharing with all of our friends at once, and then letting them sort out amongst themselves who is and isn’t interested. Though social media can create burdensome expectations to keep up with strong ties, weak ties, and everyone in between, social media platforms can also be very efficient. Using the same moment of friendship-labor to tend multiple friendships at once kills more birds with fewer stones.
  • sometimes we like the devolution of friendship. When we have to ‘pull’ friendship-content instead of receiving it in a ‘push’, we can pick and choose which content items to pull. We can ignore the baby pictures, or the pet pictures, or the sushi pictures—whatever it is our friends post that we only pretend to care about
  • I’ve been thinking since, however, on what it means to view our friends as “generalized others.” I may now feel like less of like “creepy stalker” when I click on a song in someone’s Spotify feed, but I don’t exactly feel ‘shared with’ either. Far as I know, I’ve never been SpotiVaguebooked (or SubSpotified?); I have no reason to think anyone is speaking to me personally as they listen to music, or as they choose not to disable scrobbling (if they make that choice consciously at all). I may have been granted the opportunity to view something, but it doesn’t follow that what I’m viewing has anything to do with me unless I choose to make it about me. Devolved friendship means it’s not up to us to interact with our friends personally; instead it’s now up to our friends to make our generalized broadcasts personal.
  • While I won’t go so far as to say they’re definitely ‘problems,’ there are two major things about devolved friendship that I think are worth noting. The first is the non-uniform rationalization of friendship-labor, and the second is the depersonalization of friendship-labor.
  • In short, “sharing” has become a lot easier and a lot more efficient, but “being shared with” has become much more time-consuming, demanding, and inefficient (especially if we don’t ignore most of our friends most of the time). Given this, expecting our friends to keep up with our social media content isn’t expecting them to meet us halfway; it’s asking them to take on the lion’s share of staying in touch with us. Our jobs (in this role) have gotten easier; our friends’ jobs have gotten harder.
  • The second thing worth noting is that devolved friendship is also depersonalized friendship.
  • Personal interaction doesn’t just happen on Spotify, and since I was hoping Spotify would be the New Porch, I initially found Spotify to be somewhat lonely-making. It’s the mutual awareness of presence that gives companionate silence its warmth, whether in person or across distance. The silence within Spotify’s many sounds, on the other hand, felt more like being on the outside looking in. This isn’t to say that Spotify can’t be social in a more personal way; once I started sending tracks to my friends, a few of them started sending tracks in return. But it took a lot more work to get to that point, which gets back to the devolution of friendship (as I explain below).
  • Within devolved friendship interactions, it takes less effort to be polite while secretly waiting for someone to please just stop talking.
  • When we consider the lopsided rationalization of ‘sharing’ and ‘shared with,’ as well as the depersonalization of frictionless sharing and generalized broadcasting, what becomes clear is this: the social media deck is stacked in such a way as to make being ‘a self’ easier and more rewarding than being ‘a friend.’
  • It’s easy to share, to broadcast, to put our selves and our tastes and our identity performances out into the world for others to consume; what feedback and friendship we get in return comes in response to comparatively little effort and investment from us. It takes a lot more work, however, to do the consumption, to sift through everything all (or even just some) of our friends produce, to do the work of connecting to our friends’ generalized broadcasts so that we can convert their depersonalized shares into meaningful friendship-labor.
  • We may be prosumers of social media, but the reward structures of social media sites encourage us to place greater emphasis on our roles as share-producers—even though many of us probably spend more time consuming shared content than producing it. There’s a reason for this, of course; the content we produce (for free) is what fuels every last ‘Web 2.0’ machine, and its attendant self-centered sociality is the linchpin of the peculiarly Silicon Valley concept of “Social” (something Nathan Jurgenson and I discuss together in greater detail here). It’s not super-rewarding to be one of ten people who “like” your friend’s shared link, but it can feel rewarding to get 10 “likes” on something you’ve shared—even if you have hundreds or thousands of ‘friends.’ Sharing is easy; dealing with all that shared content is hard.
  • t I wonder sometimes if the shifts in expectation that accompany devolved friendship don’t migrate across platforms and contexts in ways we don’t always see or acknowledge. Social media affects how we see the world—and how we feel about being seen in the world—even when we’re not engaged directly with social media websites. It’s not a stretch, then, to imagine that the affordances of social media platforms might also affect how we see friendship and our obligations as friends most generally.

The Stereotypes About Math That Hold Americans Back - Jo Boaler - The Atlantic - 2 views

  • Mathematics education in the United States is broken. Open any newspaper and stories of math failure shout from the pages: low international rankings, widespread innumeracy in the general population, declines in math majors. Here’s the most shocking statistic I have read in recent years: 60 percent of the 13 million two-year college students in the U.S. are currently placed into remedial math courses; 75 percent of them fail or drop the courses and leave college with no degree.
  • We need to change the way we teach math in the U.S., and it is for this reason that I support the move to Common Core mathematics.
  • One of the reasons for these results is that mathematical problems that need thought, connection making, and even creativity are more engaging for students of all levels and for students of different genders, races, and socio-economic groups. This is not only shown by my research but by decades of research in our field.

They are, in many ways, the essence of what mathematics is.  Scientists work to prove or disprove new theories by finding many cases that work or counter-examples that do not. Mathematicians, by contrast prove the validity of their propositions through justification and reasoning.
  • The young people who are successful in today’s workforce are those who can discuss and reason about productive mathematical pathways, and who can be wrong, but can trace back to errors and work to correct them.

Speed is revered in math classes across the U.S., and students as young as five years old are given timed tests—even though these have been shown to create math anxiety in young children.

Bretherton, an atmospheric researcher at the University of Washington. “I don’t think it’s intellectually honest at all.”
  • With climate policy nearly paralyzed in the United States, many other governments have also declined to take action, and worldwide emissions of greenhouse gases are soaring.
  • The most elaborate computer programs have agreed on a broad conclusion: clouds are not likely to change enough to offset the bulk of the human-caused warming. Some of the analyses predict that clouds could actually amplify the warming trend sharply through several mechanisms, including a reduction of some of the low clouds that reflect a lot of sunlight back to space. Other computer analyses foresee a largely neutral effect. The result is a big spread in forecasts of future temperature, one that scientists have not been able to narrow much in 30 years of effort.
  • The earth’s surface has already warmed about 1.4 degrees Fahrenheit since the Industrial Revolution, most of that in the last 40 years. Modest as it sounds, it is an average for the whole planet, representing an enormous addition of heat. An even larger amount is being absorbed by the oceans. The increase has caused some of the world’s land ice to melt and the oceans to rise.
  • Even in the low projection, many scientists say, the damage could be substantial. In the high projection, some polar regions could heat up by 20 or 25 degrees Fahrenheit — more than enough, over centuries or longer, to melt the Greenland ice sheet, raising sea level by a catastrophic 20 feet or more. Vast changes in  rainfall, heat waves and other weather patterns would most likely accompany such a large warming. “The big damages come if the climate sensitivity to greenhouse gases turns out to be high,” said Raymond T. Pierrehumbert, a climate scientist at the University of Chicago. “Then it’s not a bullet headed at us, but a thermonuclear warhead.”
  • But the problem of how clouds will behave in a future climate is not yet solved — making the unheralded field of cloud research one of the most important pursuits of modern science.
  • for more than a decade, Dr. Lindzen has said that when surface temperature increases, the columns of moist air rising in the tropics will rain out more of their moisture, leaving less available to be thrown off as ice, which forms the thin, high clouds known as cirrus. Just like greenhouse gases, these cirrus clouds act to reduce the cooling of the earth, and a decrease of them would counteract the increase of greenhouse gases. Dr. Lindzen calls his mechanism the iris effect, after the iris of the eye, which opens at night to let in more light. In this case, the earth’s “iris” of high clouds would be opening to let more heat escape.
  • Dr. Lindzen acknowledged that the 2009 paper contained “some stupid mistakes” in his handling of the satellite data. “It was just embarrassing,” he said in an interview. “The technical details of satellite measurements are really sort of grotesque.” Last year, he tried offering more evidence for his case, but after reviewers for a prestigious American journal criticized the paper, Dr. Lindzen published it in a little-known Korean journal. Dr. Lindzen blames groupthink among climate scientists for his publication difficulties, saying the majority is determined to suppress any dissenting views. They, in turn, contend that he routinely misrepresents the work of other researchers.
  • Ultimately, as the climate continues warming and more data accumulate, it will become obvious how clouds are reacting. But that could take decades, scientists say, and if the answer turns out to be that catastrophe looms, it would most likely be too late. By then, they say, the atmosphere would contain so much carbon dioxide as to make a substantial warming inevitable, and the gas would not return to a normal level for thousands of years.
  • In his Congressional appearances, speeches and popular writings, Dr. Lindzen offers little hint of how thin the published science supporting his position is. Instead, starting from his disputed iris mechanism, he makes what many of his colleagues see as an unwarranted leap of logic, professing near-certainty that climate change is not a problem society needs to worry about.
  • “Even if there were no political implications, it just seems deeply unprofessional and irresponsible to look at this and say, ‘We’re sure it’s not a problem,’ ” said Kerry A. Emanuel, another M.I.T. scientist. “It’s a special kind of risk, because it’s a risk to the collective civilization.”

Facebook Is Using You - NYTimes.com - 0 views

  • Facebook’s inventory consists of personal data — yours and mine.
  • Facebook makes money by selling ad space to companies that want to reach us. Advertisers choose key words or details — like relationship status, location, activities, favorite books and employment — and then Facebook runs the ads for the targeted subset of its 845 million users
  • The magnitude of online information Facebook has available about each of us for targeted marketing is stunning. In Europe, laws give people the right to know what data companies have about them, but that is not the case in the United States.

  • The bits and bytes about your life can easily be used against you. Whether you can obtain a job, credit or insurance can be based on your digital doppelgänger — and you may never know why you’ve been turned down.
  • Stereotyping is alive and well in data aggregation. Your application for credit could be declined not on the basis of your own finances or credit history, but on the basis of aggregate data — what other people whose likes and dislikes are similar to yours have done
  • Data aggregators’ practices conflict with what people say they want. A 2008 Consumer Reports poll of 2,000 people found that 93 percent thought Internet companies should always ask for permission before using personal information, and 72 percent wanted the right to opt out of online tracking. A study by Princeton Survey Research Associates in 2009 using a random sample of 1,000 people found that 69 percent thought that the United States should adopt a law giving people the right to learn everything a Web site knows about them. We need a do-not-track law, similar to the do-not-call one. Now it’s not just about whether my dinner will be interrupted by a telemarketer. It’s about whether my dreams will be dashed by the collection of bits and bytes over which I have no control and for which companies are currently unaccountable.
  • The term Weblining describes the practice of denying people opportunities based on their digital selves. You might be refused health insurance based on a Google search you did about a medical condition. You might be shown a credit card with a lower credit limit, not because of your credit history, but because of your race, sex or ZIP code or the types of Web sites you visit.
  • Advertisers are drawing new redlines, limiting people to the roles society expects them to play
  • Even though laws allow people to challenge false information in credit reports, there are no laws that require data aggregators to reveal what they know about you. If I’ve Googled “diabetes” for a friend or “date rape drugs” for a mystery I’m writing, data aggregators assume those searches reflect my own health and proclivities. Because no laws regulate what types of data these aggregators can collect, they make their own rules.
  • LAST week, Facebook filed documents with the government that will allow it to sell shares of stock to the public. It is estimated to be worth at least $75 billion. But unlike other big-ticket corporations, it doesn’t have an inventory of widgets or gadgets, cars or phones.
  • If you indicate that you like cupcakes, live in a certain neighborhood and have invited friends over, expect an ad from a nearby bakery to appear on your page.
