  • Traditional economic theory could not explain, much less predict, the near collapse of the financial system and its long-lasting effects on the global economy. Since the 2008 crisis, there has been increasing interest in using ideas from complexity theory to make sense of economic and financial markets.

  • Predicting the Next Financial CrisisWhy do financial crises occur – and when will the next one come? In the past, economic theory has failed to answer these questions. In this week’s Science Journal Perspectives, economists, physicists, epidemiologists, climate scientists and ecologists call to establish a new early warning system to avoid future global financial crises. They argue that the methods used by scientists to predict weather, traffic or disease epidemics should be used to simulate the financial systems, which could help to avoid the failures we have seen in the past. Professor Doyne tells Jack how the analysis of complex networks could and should be applied to the economy.

  • Lifetime readers know that reading literature can be transformative, but they can’t prove it. If they tried, they would have to buck the metric prejudice, the American notion that assertions unsupported with statistics are virtually meaningless. What they know about literature and its effects is literally and spiritually immeasurable. They would have to buck common marketplace wisdom, too: in an economy demanding “skill sets”—defined narrowly as technical and business skills—that deep-reading stuff won’t get you anywhere.

  • Students who learned that great scientists struggled, both personally and intellectually, outperformed those who learned only of the scientists’ great achievements, new research shows.
  • “In our culture we always say you don’t want to intimidate kids, you don’t want to tell them how hard the work is,” she noted. But the experiment showed the opposite strategy works better: Showing how great scientists had to muddle through lots of tough stuff made the subject matter real and allowed students to connect with them as people.
  • Some people learn better when the content has meaning to them. For those students, science comes to life more through personal stories than through the actual scientific content.

  • And kids who learn that intellect is a malleable thing, something to be built rather than inherited, take more academic risks and perform better. The study adds to the growing body of research in favor of teaching this “growth mindset” or the belief that the brain, like other muscles in the body, can be strengthened and improved through struggle and hard work.

  • In the nineteen-eighties, Allan Rechtschaffen and Bernard Bergmann, both, like Kleitman, sleep researchers at the University of Chicago, performed what is now considered to be one of the classic experiments in the field. It showed that rats, when totally deprived of sleep, would, after two or three weeks, drop dead. But Rechtschaffen and Bergmann could never figure out the precise cause of the rats’ deaths, and so, they wrote in a follow-up paper in 2002, even “that dramatic symptom did not tell us much about why sleep was necessary.” Rechtschaffen has observed that “if sleep doesn’t serve an absolutely vital function, it is the greatest mistake evolution ever made.”

  • Crohn’s disease affects as many as seven hundred thousand Americans, but, like other autoimmune disorders, it remains poorly understood and is considered incurable. (Autoimmune disorders are thought to arise when the immune system attacks healthy tissue, mistaking it for a threat.) The standard treatments for Crohn’s often don’t work, or work only temporarily, and many have serious side effects.
  • His mother showed him an article from the Times about a man who had been nearly bedridden by ulcerative colitis—a condition related to Crohn’s—and who had largely recovered after a month or so of fecal transplants. Gravel found a how-to book on Amazon and bought the recommended equipment: a blender, a rectal syringe, saline solution, surgical gloves, Tupperware containers. His wife agreed to be his donor.
  • New research suggests that the microbes in our guts—and, consequently, in our stool—may play a role in conditions ranging from autoimmune disorders to allergies and obesity, and reports of recoveries by patients who, with or without the help of doctors, have received these bacteria-rich infusions have spurred demand for the procedure. A year and a half ago, a few dozen physicians in the United States offered FMT. Today, hundreds do, and OpenBiome, a nonprofit stool bank founded last year by graduate students at M.I.T., ships more than fifty specimens each week to hospitals in thirty-six states. The Cleveland Clinic named fecal transplantation one of the top ten medical innovations for 2014, and biotech companies are competing to put stool-based therapies through clinical trials and onto the market. In medicine, at any rate, human excrement has become a precious commodity.

  • HERE’S an apparent paradox: Most Americans have taken high school mathematics, including geometry and algebra, yet a national survey found that 82 percent of adults could not compute the cost of a carpet when told its dimensions and square-yard price.
  • In fact, what’s needed is a different kind of proficiency, one that is hardly taught at all. The Mathematical Association of America calls it “quantitative literacy.” I prefer the O.E.C.D.’s “numeracy,” suggesting an affinity with reading and writing.
  • Many students fall by the wayside. It’s not just the difficulty of the classes. They can’t see how such formulas connect with the lives they’ll be leading.

  • Finally, we talk about how math can help us think about reorganizing the world around us in ways that make more sense. For example, there’s probably nothing more cumbersome than how we measure time: How quickly can you compute 17 percent of a week, calibrated in hours (or minutes, or seconds)? So our class undertook to decimalize time.

  • It’s an intuitive claim, but also a profound one. It asserts that the benefits of bilingualism extend well beyond the realm of language, and into skills that we use in every aspect of our lives. This view is now widespread, heralded by a large community of scientists, promoted in books and magazines, and pushed by advocacy organizations.
  • But a growing number of psychologists say that this mountain of evidence is actually a house of cards, built upon flimsy foundations.
  • Jon Andoni Duñabeitia, a cognitive neuroscientist at the Basque Center on Cognition, Brain, and Language, was one of them. In two large studies, involving 360 and 504 children respectively, he found no evidence that Basque kids, raised on Basque and Spanish at home and at school, had better mental control than monolingual Spanish children.

  • Similar controversies have popped up throughout psychology, fueling talk of a “reproducibility crisis” in which scientists struggle to duplicate classic textbook results. In many of these cases, classic psychological phenomena that seem to be backed by years of supportive evidence, suddenly become fleeting and phantasmal. The causes are manifold. Journals are more likely to accept positive, attention-grabbing papers than negative, contradictory ones, which pushes scientists towards running small studies or tweaking experiments on the fly—practices that lead to flashy, publishable discoveries that may not actually be true.

  • To what extent can we and should we aspire to create machines that can outthink us? For example, Netflix has an algorithm that can predict what movies you will like based on the ones you've already seen and rated. Suppose a dating site were to develop a similar algorithm—maybe even a more sophisticated one—and predict with some accuracy which partner would be the best match for you. Whose advice would you trust more? The advice of the smart dating app or the advice of your parents or your friends?
  • The question, it seems to me, is should we use new genetic technologies only to cure disease and repair injury, or also to make ourselves better-than-well. Should we aspire to become the masters of our natures to protect our children and improve their life prospects?AdvertisementAdvertisement This goes back to the role of accident. Is the unpredictability of the child an important precondition of the unconditional love of parents for children? My worry is that if we go beyond health, we run the risk of turning parenthood into an extension of the consumer society.

  • Fact can be stranger than fiction. This is especially true of black holes, as Prof Stephen Hawking explains.For instance as soon as you entered the black hole, reality would split in two. "In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed," as we have previously explored.In the 2016 Reith lectures broadcast on BBC Radio 4, Prof Hawking further examines and challenges the latest scientific thinking about black holes.

What Google Learned From Its Quest to Build the Perfect Team - The New York Times - 1 views

  • Five years ago, Google — one of the most public proselytizers of how studying workers can transform productivity — became focused on building the perfect team. In the last decade, the tech giant has spent untold millions of dollars measuring nearly every aspect of its employees’ lives. Google’s People Operations department has scrutinized everything from how frequently particular people eat together (the most productive employees tend to build larger networks by rotating dining companions) to which traits the best managers share (unsurprisingly, good communication and avoiding micromanaging is critical; more shocking, this was news to many Google managers).The company’s top executives long believed that building the best teams meant combining the best people. They embraced other bits of conventional wisdom as well, like ‘‘It’s better to put introverts together,’’ said Abeer Dubey, a manager in Google’s People Analytics division, or ‘‘Teams are more effective when everyone is friends away from work.’’ But, Dubey went on, ‘‘it turned out no one had really studied which of those were true.’’In 2012, the company embarked on an initiative — code-named Project Aristotle — to study hundreds of Google’s teams and figure out why some stumbled while others soared.
  • As they struggled to figure out what made a team successful, Rozovsky and her colleagues kept coming across research by psychologists and sociologists that focused on what are known as ‘‘group norms.’’
  • As the researchers studied the groups, however, they noticed two behaviors that all the good teams generally shared. First, on the good teams, members spoke in roughly the same proportion, a phenomenon the researchers referred to as ‘‘equality in distribution of conversational turn-taking.’’ On some teams, everyone spoke during each task; on others, leadership shifted among teammates from assignment to assignment. But in each case, by the end of the day, everyone had spoken roughly the same amount. ‘‘As long as everyone got a chance to talk, the team did well,’’ Woolley said. ‘‘But if only one person or a small group spoke all the time, the collective intelligence declined.’’Second, the good teams all had high ‘‘average social sensitivity’’ — a fancy way of saying they were skilled at intuiting how others felt based on their tone of voice, their expressions and other nonverbal cues. One of the easiest ways to gauge social sensitivity is to show someone photos of people’s eyes and ask him or her to describe what the people are thinking or feeling — an exam known as the Reading the Mind in the Eyes test. People on the more successful teams in Woolley’s experiment scored above average on the Reading the Mind in the Eyes test. They seemed to know when someone was feeling upset or left out. People on the ineffective teams, in contrast, scored below average. They seemed, as a group, to have less sensitivity toward their colleagues.

  • A landmark 2015 report that cast doubt on the results of dozens of published psychology studies has exposed deep divisions in the field, serving as a reality check for many working researchers but as an affront to others who continue to insist the original research was sound. On Thursday, a group of four researchers publicly challenged the report, arguing that it was statistically flawed and, as a result, wrong.The 2015 report, called the Reproducibility Project, found that less than 40 studies in a sample of 100 psychology papers in leading journals held up when retested by an independent team. The new critique by the four researchers countered that when that team’s statistical methodology was adjusted, the rate was closer to 100 percent.

  • Nuremberg is not alone in dealing anew with its Nazi heritage. The entire country has been swept into a debate this year about the release of a new edition of “Mein Kampf,” the first time Hitler’s book has been published in Germany in 70 years. Both clashes come as Germany faces the reemergence of xenophobia that has flared as the country sits at the center of Europe’s refugee crisis. Some worry that both the book and the buildings, if renovated, will become rallying points for today’s neo-Nazis. 
  • The debates in Germany highlight a fundamental question that many countries in the world struggle with: What do you do with symbols of a past that many people today find abhorrent?In the United States, fights over the display of the Confederate flag in public places surface almost weekly. Ukraine is systematically removing statues of Vladimir Lenin and other totems of the country’s Soviet past. In Spain, where authorities in Madrid are renaming streets that commemorate Francisco Franco, divisions simmer over demands to remove the late dictator’s body from the vast monument named  Valley of the Fallen that glorifies his reign.The Rising Sun flag – a controversial symbol of Japan’s imperial history – is still used by the country’s Maritime Self-Defense Force, much to the anger of Japan’s neighbors. Britain has been embroiled in a controversy over whether to remove a statue of Cecil Rhodes – for whom the prestigious Rhodes scholarship is named – from a college at Oxford University because of critics’ concerns about his ties to Southern Africa’s colonial and racist past. The university says it will stay right where it is.
  • Yet in few places do historical symbols evoke more sensitivity than in Germany.

  • Philosophy is important for more than just a while, and has serious, practical uses for all of society. There are countless examples of philosophy of mind theories’ relevance to neuroscientists, or cases where political philosophers have shaped politicians.
  • The 18th century philosopher David Hume’s argument that we don’t have a reasonable understanding of causation at all, but only presume cause and effect when two things have been observed as conjoined in the past, is notoriously difficult to refute. The problem underlies much of physics and is hardly insignificant.

  • The spectacular success of science in the past 300 years has raised hopes that it also holds the key to guiding human beings towards a good life. Psychology and neuroscience has become a main source of life advice in the popular media. But philosophers have long held reservations about this scientific orientation to how to live life.
  • The 18th century Scottish philosopher David Hume, for instance, famously pointed out, no amount of fact can legislate value, moral or otherwise. You cannot derive ought from is.
  • Science is the best method we have for approaching the world objectively. But in fact it is not science per se that is the problem, from the point of view of subjectivity. It is objectivizing, in any of its forms. One can frame a decision, for example, in objective terms. One might decide between career choices by weighing differences in workloads, prestige, pay and benefits between, say, working for an advanced technology company versus working for a studio in Hollywood. We are often encouraged to make choices by framing them in this way. Alternatively, one might try to frame the decision more in terms of what it might be like to work in either occupation; in this case, one needs to have the patience to dwell in experience long enough for one’s feelings about either alternative to emerge. In other words, one might deliberate subjectively.

  • Most commonly, we turn our back on subjectivity to escape from pain. Suffering, one’s own, or others’, might become bearable, one hopes, when one takes a step back and views it objectively, conceptually, abstractly. And when it comes to something as monumental as the Holocaust, one’s mind cannot help but be numbed by the sheer magnitude of it. How could one feel the pain of all those people, sympathize with millions? Instead one is left with the “facts,” the numbers.

  • There are generally two, radically different ways to relate to the world: objective and subjective. Objectivity is an orientation towards reality based on abstracting away, in various degrees, from subjective experience, and from individual points of view. A subjective orientation, on the other hand, is based on an attunement to the inner experience of feeling, sensing, thinking and valuing that unfolds in our day-to-day living. This distinction has been brought into contemporary philosophical discourse most notably by Thomas Nagel, in a number of his essays, most famously in “What Is It Like to Be a Bat?”The spectacular success of science in the past 300 years has raised hopes that it also holds the key to guiding human beings towards a good life. Psychology and neuroscience has become a main source of life advice in the popular media. But philosophers have long held reservations about this scientific orientation to how to live life. The 18th century Scottish philosopher David Hume, for instance, famously pointed out, no amount of fact can legislate value, moral or otherwise. You cannot derive ought from is. But there is another, in some way more radical concern, expressed in Western philosophy most forcefully by Kierkegaard, and in literature by Dostoyevsky — two religiously inspired thinkers — namely that our experience of life matters in ineffable ways that no objective understanding of the world can capture.
