  • America’s Real Digital Divide - The New York Times
    https://www.nytimes.com/2018/02/11/opinion/america-digital-divide.html

    A group of former Facebook and Google employees last week began a campaign to change the tech companies they had a hand in creating. The initiative, called Truth About Tech, aims to push these companies to make their products less addictive for children — and it’s a good start.

    But there’s more to the problem. If you think middle-class children are being harmed by too much screen time, just consider how much greater the damage is to minority and disadvantaged kids, who spend much more time in front of screens.

    According to a 2011 study by researchers at Northwestern University, minority children watch 50 percent more TV than their white peers, and they use computers for up to one and a half hours longer each day. White children spend eight hours and 36 minutes looking at a screen every day, according to a survey by the Kaiser Family Foundation, while black and Hispanic children spend 13 hours.

    While some parents in more dangerous neighborhoods understandably think that screen time is safer than playing outside, the deleterious effects of too much screen time are abundantly clear. Screen time has a negative effect on children’s ability to understand nonverbal emotional cues; it is linked to higher rates of mental illness, including depression; and it heightens the risk for obesity.

    Make no mistake: The real digital divide in this country is not between children who have access to the internet and those who don’t. It’s between children whose parents know that they have to restrict screen time and those whose parents have been sold a bill of goods by schools and politicians that more screens are a key to success. It’s time to let everyone in on the secret.

    Un point revue partial et peu argumenté, mais qu’il faut intégrer dans une réflexion plus vaste sur les usages de l’internet en fonction des classes sociales.

  • The Case for Less Solidarity - Issue 48: Chaos

    There’s a lot of talk in this country about the federal deficit,” then-Senator Barack Obama said in a 2006 commencement address at Northwestern University. “But I think we should talk more about our empathy deficit.” What we need, he said, was the ability to “see the world through those who are different from us.” Since Obama’s speech, the phrase “empathy deficit” has gained a foothold, appearing everywhere from academic journals to mainstream media outlets. Among the varied responses to the 2016 United States presidential election were calls for a greater general empathy. Many liberals tried to peer across party lines to understand the motivations of Donald Trump voters, for instance interviewing Republican constituents and reading books about rural poverty (think J.D. Vance’s Hillbilly Elegy (...)

  • A psychological history of the #NSA

    Peter Ludlow, a philosopher at Northwestern University, pointed to the sociologist Robert Jackall’s 1988 book, Moral Mazes, for a description of the rules that govern such bureaucracies: “(1) You never go around your boss. (2) You tell your boss what he wants to hear, even when your boss claims that he wants dissenting views. (3) If your boss wants something dropped, you drop it. (4) You are sensitive to your boss’s wishes so that you anticipate what he wants; you don’t force him, in other words, to act as a boss. (5) Your job is not to report something that your boss does not want reported, but rather to cover it up. You do your job and you keep your mouth shut.”

    “The NSA is nothing if not a 1950s-style bureaucracy,” Ludlow told me. “The consequence of that is you’re almost guaranteed to do evil.”

  • Brain Controls Paralyzed Muscles | The Scientist

    Scientists at Northwestern University have developed a device that allows monkeys to reach out and grab a ball, even though they cannot feel some of their arm muscles. A panel of electrodes implanted in the monkeys’ brains decodes commands from the motor cortex (the region that controls movements), while electrodes in their arms directly stimulate the appropriate muscles.
