Gaming the College Rankings - NYTimes.com - 0 views

  •  
    "Any love-hate relationship must have its share of pain, so the academic world, in its obsession with college rankings, is suitably dismayed by news that an elite college, Claremont McKenna, fudged its numbers in an apparent bid to climb the charts. Claremont McKenna in California is the latest but not the only college to have admitted submitting false information in an effort to win a high rating. Dismayed, but not quite surprised. In fact, several colleges in recent years have been caught gaming the system - in particular, the avidly watched U.S. News & World Report rankings - by twisting the meanings of rules, cherry-picking data or just lying. In one recent example, Iona College in New Rochelle, north of New York City, acknowledged last fall that its employees had lied for years not only about test scores, but also about graduation rates, freshman retention, student-faculty ratio, acceptance rates and alumni giving. Other institutions have found ways to manipulate the data without outright dishonesty. In 2008, Baylor University offered financial rewards to admitted students to retake the SAT in hopes of increasing its average score. Admissions directors say that some colleges delay admission of low-scoring students until January, excluding them from averages for the class admitted in September, while other colleges seek more applications to report a lower percentage of students accepted. Claremont McKenna, according to Robert Morse, the director of data research at U.S. News, is "the highest-ranking school to have to go through this publicly and have to admit to misreporting." This year, U.S. News rated it as the nation's ninth-best liberal arts college. There is no reason to think the U.S. News rankings are rife with misinformation, and the publication makes efforts to police the data, adjust its metrics and close loopholes. But repeated revelations of manipulation show the importance of the rankings in the minds of prospective students, thei

How Companies Learn Your Secrets - NYTimes.com - 0 views

    "Andrew Pole had just started working as a statistician for Target in 2002, when two colleagues from the marketing department stopped by his desk to ask an odd question: "If we wanted to figure out if a customer is pregnant, even if she didn't want us to know, can you do that? " Multimedia How to Break the Cookie Habit This article is adapted from "The Power of Habit: Why We Do What We Do in Life and Business," which will be published on Feb. 28. More in the Magazine » Readers' Comments Share your thoughts. Post a Comment » Read All Comments (35) » Pole has a master's degree in statistics and another in economics, and has been obsessed with the intersection of data and human behavior most of his life. His parents were teachers in North Dakota, and while other kids were going to 4-H, Pole was doing algebra and writing computer programs. "The stereotype of a math nerd is true," he told me when I spoke with him last year. "I kind of like going out and evangelizing analytics." As the marketers explained to Pole - and as Pole later explained to me, back when we were still speaking and before Target told him to stop - new parents are a retailer's holy grail. Most shoppers don't buy everything they need at one store. Instead, they buy groceries at the grocery store and toys at the toy store, and they visit Target only when they need certain items they associate with Target - cleaning supplies, say, or new socks or a six-month supply of toilet paper. But Target sells everything from milk to stuffed animals to lawn furniture to electronics, so one of the company's primary goals is convincing customers that the only store they need is Target. But it's a tough message to get across, even with the most ingenious ad campaigns, because once consumers' shopping habits are ingrained, it's incredibly difficult to change them. There are, however, some brief periods in a person's life when old routines fall apart and

The decline effect and the scientific method : The New Yorker - 1 views

  •  
    "n September 18, 2007, a few dozen neuroscientists, psychiatrists, and drug-company executives gathered in a hotel conference room in Brussels to hear some startling news. It had to do with a class of drugs known as atypical or second-generation antipsychotics, which came on the market in the early nineties. The drugs, sold under brand names such as Abilify, Seroquel, and Zyprexa, had been tested on schizophrenics in several large clinical trials, all of which had demonstrated a dramatic decrease in the subjects' psychiatric symptoms. As a result, second-generation antipsychotics had become one of the fastest-growing and most profitable pharmaceutical classes. By 2001, Eli Lilly's Zyprexa was generating more revenue than Prozac. It remains the company's top-selling drug. But the data presented at the Brussels meeting made it clear that something strange was happening: the therapeutic power of the drugs appeared to be steadily waning. A recent study showed an effect that was less than half of that documented in the first trials, in the early nineteen-nineties. Many researchers began to argue that the expensive pharmaceuticals weren't any better than first-generation antipsychotics, which have been in use since the fifties. "In fact, sometimes they now look even worse," John Davis, a professor of psychiatry at the University of Illinois at Chicago, told me. "

Top 10 Most Famous Scientific Theories (That Turned out to be Wrong) | Top 10 Lists | TopTenz.net - 1 views

  •  
    "One of the best aspects of science has always been its readiness to admit when it got something wrong. Theories are constantly being refigured, and new research frequently renders old ideas outdated or incomplete. But this hasn't stopped some discoveries from being hailed as important, game-changing accomplishments a bit prematurely. Even in a field as rigorous and detail-oriented as science, theories get busted, mistakes are made, and hoaxes are perpetrated. The following are ten of the most groundbreaking of these scientific discoveries that turned out to be resting on some questionable data. It is worth noting that most of these concepts are not necessarily "wrong" in the traditional sense; rather, they have been replaced by other theories that are more complete and reliable."

New York Study of Pedestrian Victims Leads to Unexpected Conclusions - NYTimes.com - 0 views

      A human/social science study of the streets of NYC.
  • Taxis, it turns out, are not a careering menace: cabs, along with buses and trucks, accounted for far fewer pedestrian accidents in Manhattan than did private automobiles. Jaywalkers were involved in fewer collisions than their law-abiding counterparts who waited for the “walk” sign, though they were likelier to be killed or seriously hurt by the collision.

The city says it is already planning a series of street changes based on data in the report.

Do Daughters Cause Divorce? - NYTimes.com - 3 views

  •  
    Parents of girls are 5 percent more likely to divorce than parents of boys. Economists first analyzed the data that way in 2003, when Gordon Dahl at the University of Rochester and Enrico Moretti at U.C.L.A., identified that gap, and noted that it widened as you added boys or girls to a family. Parents of three girls, for instance, are 10 percent more likely to split than are parents of three boys. And, they found, an unmarried couple is more likely to marry if they learn their unborn child will be a boy than a girl.

Why Language May Shape Our Thoughts - Newsweek - 0 views

  •  
    "When the Viaduct de Millau opened in the south of France in 2004, this tallest bridge in the world won worldwide accolades. German newspapers described how it "floated above the clouds" with "elegance and lightness" and "breathtaking" beauty. In France, papers praised the "immense" "concrete giant." Was it mere coincidence that the Germans saw beauty where the French saw heft and power? Lera Boroditsky thinks not. A psychologist at Stanford University, she has long been intrigued by an age-old question whose modern form dates to 1956, when linguist Benjamin Lee Whorf asked whether the language we speak shapes the way we think and see the world. If so, then language is not merely a means of expressing thought, but a constraint on it, too. Although philosophers, anthropologists, and others have weighed in, with most concluding that language does not shape thought in any significant way, the field has been notable for a distressing lack of empiricism-as in testable hypotheses and actual data."

'Pre-crime' Comes to the HR Dept. - Datamation.com - 0 views

  •  
    "A Santa Barbara, Calif., startup called Social Intelligence data-mines the social networks to help companies decide if they really want to hire you. While background checks, which mainly look for a criminal record, and even credit checks have become more common, Social Intelligence is the first company that I'm aware of that systematically trolls social networks for evidence of bad character. Using automation software that slogs through Facebook, Twitter, Flickr, YouTube, LinkedIn, blogs, and "thousands of other sources," the company develops a report on the "real you" -- not the carefully crafted you in your resume. The service is called Social Intelligence Hiring. The company promises a 48-hour turn-around. Because it's illegal to consider race, religion, age, sexual orientation and other factors, the company doesn't include that information in its reports. Humans review the reports to eliminate false positives. And the company uses only publically shared data -- it doesn't "friend" targets to get private posts, for example. The reports feature a visual snapshot of what kind of person you are, evaluating you in categories like "Poor Judgment," "Gangs," "Drugs and Drug Lingo" and "Demonstrating Potentially Violent Behavior." The company mines for rich nuggets of raw sewage in the form of racy photos, unguarded commentary about drugs and alcohol and much more. "

Is Economics a Science? - The American, A Magazine of Ideas - 0 views

  •  
    "Economics aspires to be a science. But in this it does not succeed. Neither does finance. This despite the fact that there is an annual, optimistically named Nobel Prize in "Economic Sciences." Financial crises keep happening-the list is long. Could they be avoided if economics and finance were science? To paraphrase financial observer James Grant: science is progressive, but finance is cyclical. But why should this be? Do we not learn from experience? Does economic knowledge not increase? And how about having computers, vast amounts of data and information, and new mathematical models to guide lending and investing decisions?"

A's for Good Behavior - NYTimes.com - 0 views

    "A few years ago, teachers at Ellis Middle School in Austin, Minn., might have said that their top students were easy to identify: they completed their homework and handed it in on time; were rarely tardy; sat in the front of the class; wrote legibly; and jumped at the chance to do extra-credit assignments. But after poring over four years of data comparing semester grades with end-of-the-year test scores on state subject exams, the teachers at Ellis began to question whether they really knew who the smartest students were. About 10 percent of the students who earned A's and B's in school stumbled during end-of-the-year exams. By contrast, about 10 percent of students who scraped along with C's, D's and even F's - students who turned in homework late, never raised their hands and generally seemed turned off by school - did better than their eager-to-please B+ classmates.

MP3: Scientific Attempt To Create Most Annoying Song Ever | Listening Post - 1 views

  •  
    "An online poll conducted in the '90s set Vitaly Komar, Alex Melamid and David Soldier on a quest to create the most annoying song ever. After gathering data about people's least favorite music and lyrical subjects, they did the unthinkable: they combined them into a single monstrosity, specifically engineered to sound unpleasant to the maximum percentage of listeners. The song is not new, but it resurfaced on Dial "M" for Musicology. Amazingly, this "most unwanted music" contains little dissonance - that would have been too easy. For the most part, they seem to have tried to assemble these elements in a listenable way. Komar & Melamid and David Soldier's list of undesirable elements included holiday music, bagpipes, pipe organ, a children's chorus and the concept of children in general (really?), Wal-Mart, cowboys, political jingoism, George Stephanopoulos, Coca Cola, bossanova synths, banjo ferocity, harp glissandos, oompah-ing tubas and much, much more. It's actually a fascinating listen, worthwhile for the opera rapping alone. (We didn't think that was possible either.)"

The Science of Why We Don't Believe Science | Mother Jones - 0 views

    "In the annals of denial, it doesn't get much more extreme than the Seekers. They lost their jobs, the press mocked them, and there were efforts to keep them away from impressionable young minds. But while Martin's space cult might lie at on the far end of the spectrum of human self-delusion, there's plenty to go around. And since Festinger's day, an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts. The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds-fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself."

Currents - Are Metrics Blinding Our Perception? - NYTimes.com - 1 views

  • Computers have become an extension of us: that is a commonplace now. But in an important way we may be becoming an extension of them, in turn. Computers are digital — that is, they turn everything into numbers; that is their way of seeing. And in the computer age we may be living through the digitization of our minds, even when they are offline: a slow-burning quantification of human affairs that promises or threatens, depending on your outlook, to crowd out other categories of the imagination, other ways of perceiving.
  • Welcome to the Age of Metrics — or to the End of Instinct. Metrics are everywhere. It is increasingly with them that we decide what to read, what stocks to buy, which poor people to feed, which athletes to recruit, which films and restaurants to try.

For Law School Graduates, Debts if Not Job Offers - NYTimes.com - 1 views

    "IF there is ever a class in how to remain calm while trapped beneath $250,000 in loans, Michael Wallerstein ought to teach it. Here he is, sitting one afternoon at a restaurant on the Upper East Side of Manhattan, a tall, sandy-haired, 27-year-old radiating a kind of surfer-dude serenity. His secret, if that's the right word, is to pretty much ignore all the calls and letters that he receives every day from the dozen or so creditors now hounding him for cash. "And I don't open the e-mail alerts with my credit score," he adds. "I can't look at my credit score any more." Mr. Wallerstein, who can't afford to pay down interest and thus watches the outstanding loan balance grow, is in roughly the same financial hell as people who bought more home than they could afford during the real estate boom. But creditors can't foreclose on him because he didn't spend the money on a house. "
