"wet bias"

From: Retronaut

"Predictions are hard—especially about the future. It must have taken superhuman will for New York Times FiveThirtyEight blogger and columnist Nate Silver to avoid quoting Yogi Berra in the course of writing his engaging and sophisticated new book, The Signal and the Noise, especially because the line is so directly on point. The essential problem of prediction is that while forecasts are 'about' the future, the data on which they’re based are generally data about the past….
     Good forecasters are meticulous, open-minded, eager for more data, and rigorous in checking their ideas. You want foxes, in Isaiah Berlin’s terms, rather than hedgehogs who simply assimilate new information into a strongly held big idea. Ideologues do a poor job of making political forecasts, presumably for reasons of bias. It’s easier to make good predictions when you have large samples of solid data, as in baseball, than when forced to deal with sketchy information or small samples.
     Forecasts may even be deliberately biased: The National Weather Service is pretty good at short-term weather predictions, but local TV newscasts deliberately and systematically overstate the chances of rain. This 'wet bias' occurs because the audience is more upset when they’re caught in an unexpected shower without their umbrella than when predicted rain fails to materialize."

Slow Food. For Thought



"In her new book, “The Republic of Noise,” New York City public school educator and curriculum advisor Diana Senechal argues that one reason for this problem [academic failure] is the students’ loss of solitude: the ability to think and reflect independently on a given topic. Schools have become more concerned with the business of keeping students busy in what Senechal deems is a flawed attempt to ensure student engagement. But as a result, students are not given the time and space to devote themselves completely to the study and understanding of one specific thing. It’s a need she finds reflected in our culture as a whole: We are a nation glued to smartphones and computer screens, checking email and Twitter feeds in our need to stay in some loop by reading and responding to rolling updates. [...]
    Solitude is not about being in a hut out in the woods or being out in the desert or living without other people around. I define solitude as a certain apartness that we always have, whether we’re among others or not. It is something that can be practiced — maybe to think just on one’s own, even when in a meeting or in a group and so forth — but that also has been nurtured by time alone. So there’s an ongoing solitude that’s always there, and there’s also a shaped or practiced solitude, which requires both time alone with things, to be thinking about things and working on things, and time among others when you nonetheless think independently. [...]
     'What I see is people having great difficulty sitting with a book for a long time, or with a pad of paper,' [says Ms. Senechal]. 'They want to have the stimulus right nearby – they want access to their email, they want access to their text messages no matter what they’re doing. You see people walking down the street with their phones and just staring at their phones; and you see people holding their phones in all situations – at a concert or when having dinner with a friend – so they can check that they don’t miss anything. Yes, there is a loss of ability to just sit with something.'"

Write Out of Nothing

Photo: Michael Hale



"What should you do to help your child pursue her dreams of becoming a writer?
     First of all, let her be bored. Let her have long afternoons with absolutely nothing to do. Limit her TV-watching time and her internet-playing time and take away her cell phone. Give her a whole summer of lazy mornings and dreamy afternoons. Make sure she has a library card and a comfy corner where she can curl up with a book. Give her a notebook and five bucks so she can pick out a great pen. [...] Give her some tedious chores to do. Make her mow the lawn, do the dishes by hand, paint the garage. Make her go on long walks with you and tell her you just want to listen to the sounds of the neighborhood.
     [...] Let her go without writing if she wants to. Never nag her about writing, even if she’s cheerful when writing and completely unbearable when she’s not. Let her quit writing altogether if she wants to." — M. Molly Backes

"Start by doing nothing while you are waiting in line, at the doctor’s office, on a bus, or for a plane. Wait, without reading a newspaper or magazine, without talking on the phone, without checking your email, without writing out your to-do list, without doing any work, without worrying about what you need to do later. Wait, and do nothing. Concentrate on your breathing, or try one of the relaxation techniques above. Concentrate on those around you — watch them, try to understand them, listen to their conversations." — zenhabits

Be. Quiet.

From: One Good Eye Antiques

"In his gorgeous little book The Lost Art of Reading — Why Books Matter in a Distracted Time the critic David Ulin admits to a strange feeling. All his life, he had taken reading as for granted as eating — but then, a few years ago, he 'became aware, in an apartment full of books, that I could no longer find within myself the quiet necessary to read.' [...]
The idea of keeping yourself on a digital diet will, I suspect, become mainstream soon. Just as I've learned not to stock my fridge with tempting carbs, I've learned to limit my exposure to the web [...]
And here's the function that the book — the paper book that doesn't beep or flash or link or let you watch a thousand videos all at once — does for you that nothing else will. It gives you the capacity for deep, linear concentration. As Ulin puts it: 'Reading is an act of resistance in a landscape of distraction... It requires us to pace ourselves. It returns us to a reckoning with time. In the midst of a book, we have no choice but to be patient, to take each thing in its moment, to let the narrative prevail. We regain the world by withdrawing from it just a little, by stepping back from the noise.'"
