Ninth Planet May Exist in Solar System Beyond Pluto, New Evidence Suggests - The New Yo... - 1 views

  • What Dr. Brown and a fellow Caltech professor, Konstantin Batygin, have not done is actually find that planet
  • Rather, in a paper published Wednesday in The Astronomical Journal, Dr. Brown and Dr. Batygin lay out a detailed circumstantial argument for the planet’s existence in what astronomers have observed — a half-dozen small bodies in distant, highly elliptical orbits.
  • This would be the second time that Dr. Brown has upended the map of the solar system. In January 2005, he discovered a Pluto-size object, now known as Eris, in the ring of icy debris beyond Neptune known as the Kuiper belt.A year and a half later, the International Astronomical Union placed Pluto in a new category, “dwarf planet,” because it had not “cleared the neighborhood around its orbit.”In the view of the astronomical union, a full-fledged planet must be, in essence, the gravitational bully of its orbit, and Pluto was not.

Why are shoppers being asked to buy ethically or not in the first place? - Quartz - 3 views

  • A series of studies suggests that, while a product’s ethics may influence purchasing decisions, many shoppers choose simply not to know whether something was ethically made. That includes shoppers who care about social responsibility. And shoppers who ignore ethical matters can even develop a negative opinion about people who do express ethical concerns—which makes them even less likely to pay attention to ethical issues in the future.
  • “You feel badly that you were not ethical when someone else was,” Rebecca Reczek, a professor of marketing at Ohio State University and one of the study’s authors, told NPR about the results. “It’s a threat to your sense of self, to your identity. So to recover from that, you put the other person down.”
  • International supply chains, she points out, are notoriously opaque, and the free market doesn’t have any good way to deal with the way this system stifles information. It might be best, she says, if these matters were regulated before the products even reached consumers, taking ethical dilemmas out of the shopping equation. Of the unethical choice, like a polluting car or a shirt made with exploited labor, she suggests: “Maybe we just shouldn’t have it available.”

How Measurement Fails Doctors and Teachers - The New York Times - 1 views

  • TWO of our most vital industries, health care and education, have become increasingly subjected to metrics and measurements. Of course, we need to hold professionals accountable. But the focus on numbers has gone too far. We’re hitting the targets, but missing the point.
  • We also need more research on quality measurement and comparing different patient populations. The only way to understand whether a high mortality rate, or dropout rate, represents poor performance is to adequately appreciate all of the factors that contribute to these outcomes — physical and mental, social and environmental — and adjust for them.
  • He developed what is known as Donabedian’s triad, which states that quality can be measured by looking at outcomes (how the subjects fared), processes (what was done) and structures (how the work was organized).

There's a good reason Americans are horrible at science - Quartz - 0 views

  • There are a number of problems with teaching science as a collection of facts. First, facts change. Before oxygen was discovered, the theoretical existence of phlogiston made sense. For a brief, heady moment in 1989, it looked like cold fusion (paywall) was going to change the world. In the field of medical science, “facts” are even more wobbly. For example, it has been estimated that fewer than 10% of published high profile cancer studies are reproducible (the word “reproducible” here is a euphemism for “not total poppycock”).
  • It’s not possible for everyone—or anyone—to be sufficiently well trained in science to analyze data from multiple fields and come up with sound, independent interpretations. I spent decades in medical research, but I will never understand particle physics, and I’ve forgotten almost everything I ever learned about inorganic chemistry. It is possible, however, to learn enough about the powers and limitations of the scientific method to intelligently determine which claims made by scientists are likely to be true and which deserve skepticism. As a starting point, we could teach our children that the theories and technologies that have been tested the most times, by the largest number of independent observers, over the greatest number of years, are the most likely to be reliable.

When Philosophy Lost Its Way - The New York Times - 0 views

  • Having adopted the same structural form as the sciences, it’s no wonder philosophy fell prey to physics envy and feelings of inadequacy. Philosophy adopted the scientific modus operandi of knowledge production, but failed to match the sciences in terms of making progress in describing the world. Much has been made of this inability of philosophy to match the cognitive success of the sciences. But what has passed unnoticed is philosophy’s all-too-successful aping of the institutional form of the sciences. We, too, produce research articles. We, too, are judged by the same coin of the realm: peer-reviewed products. We, too, develop sub-specializations far from the comprehension of the person on the street. In all of these ways we are so very “scientific.”

Fixing the Eyewitness Problem - The New Yorker - 0 views

  • n a dissenting opinion in 1981, Supreme Court Justice William Brennan wrote that “eyewitness identification evidence is notoriously unreliable.” Dozens of scientific studies support this claim. Nevertheless, eyewitness testimony continues to be used widely, and many criminal cases hinge on it almost exclusively. Since 1989, two hundred and eighty people have been exonerated of sexual-assault charges in the U.S. Nearly three-quarters of those wrongful convictions relied, in whole or in part, on a mistaken identification by an eyewitness. Psychologists have long recognized that human memory is highly fallible. Hugo Münsterberg taught in one of the first American psychology departments, at Harvard. In a 1908 book called “On the Witness Stand,” he argued that, because people could not know when their memories had deceived them, the legal system’s safeguards against lying—oaths, penalties for perjury, and so on—were ineffective. He expected that teachers, doctors, and politicians would all be eager to reform their fields. “The lawyer alone is obdurate,” Münsterberg wrote.

This Bizarre Illusion Makes Dots In Plain View Disappear | IFLScience - 1 views

  • the reason you are not seeing the yellow dots is due to a phenomenon called sensory overload. As the grid around the green dot rotates, and the yellow dots remain unmoving and unchanging, the brain processes the yellow dots as unnecessary information and blanks them out. The brain, after all, does not automatically process all information, visual or otherwise, that the body’s sensory systems encounter. If it did, it would overload, so it tends to filter out information that it has repeatedly encountered without change. The Yale study suggests something else. Instead of the brain automatically removing pieces of unchanging information from view due to sensory overload, the mind is in fact perceiving the objects as contrary to the logic of real-life perceptions. The brain simply does not accept that the object can logically exist based on what information it has. Thus, they disappear from view – they become perceptual scotomas.

BBC World Service - The Why Factor, Group Thinking - 0 views

  • Anyone who has ever been in a meeting has seen the phenomenon of "Groupthink" first hand. The will of the crowd over shadows the wisdom of individuals and it can lead to dangerous consequences. Mike Williams asks why humans succumb to "Groupthink" and how we fight the tendency to follow the herd even if it leads to very perilous outcomes.

The Six Most Interesting Psychology Papers of 2015 - The New Yorker - 1 views

  • “Estimating the Reproducibility of Psychological Science,” from Science This paper isn’t really a study; it’s the outcome of an important movement in the field of psychology. In an effort called the Reproducibility Project, researchers at dozens of universities collaborated to replicate a hundred psychology studies that were initially conducted in 2008. They ended up replicating between a third and half of the studies. Is that result bad or good? It’s inevitable that studies won’t always be replicable—if every study could be replicated, then every researcher would be right the first time; even legitimate findings can prove fragile when you try to repeat them. All the same, the paper concludes that there is “room for improvement” in psychology, especially when it comes to “cultural practices in scientific communication.” Specifically, the authors propose that “low-power research designs combined with publication bias favoring positive results together produce a literature with upwardly biased effect sizes.” In other words, the desire for novelty drives researchers to overestimate the conclusiveness of their own work. It’s a fascinating and valuable effort to make sure that psychology moves forward in the best way possible.

Disputing Korean Narrative on 'Comfort Women,' a Professor Draws Fierce Backlash - The ... - 0 views

  • women” in 2013, Park Yu-ha wrote that she felt “a bit fearful” of how it might be received. After all, she said, it challenged “the common knowledge” about the wartime sex slaves.But even she was not prepared for the severity of the backlash.In February, a South Korean court ordered Ms. Park’s book, “Comfort Women of the Empire,” redacted in 34 sections where it found her guilty of defaming former comfort women with false facts. Ms. Park is also on trial on the criminal charge of defaming the aging women, widely accepted here as an inviolable symbol of Korea’s suffering under colonial rule by Japan and its need for historical justice, and she is being sued for defamation by some of the women themselves.

Guns are now killing as many people as cars in the U.S. - The Washington Post - 0 views

  • Medical ailments, such as cancer and heart attacks, kill considerably more people each year than either guns or automobiles, according to the CDC. But firearms and motor vehicles are among the leading non-medical causes of mortality in the United States. They kill more people than falls do each year, and considerably more people than alcohol.

The Washington Post Style Guide Now Accepts Singular 'They' | Mental Floss - 0 views

  • Proponents of singular they have long argued that the prohibition makes no sense. Not only is it natural, it has been used in English for centuries. It’s in the King James Bible. Authors like Chaucer, Shakespeare, Swift, Austen, Thackeray, and Shaw used it. Before the production of school textbooks for grammar in the 19th century, no one complained about it or even noticed it. Avoiding it is awkward or necessitates sexist language. Now, in the most recent update to The Washington Post style guide, singular they has been given official approval.
  • it is “the only sensible solution to English’s lack of a gender-neutral third-person singular personal pronoun.”

Are These 10 Lies Justified? - The New York Times - 0 views

  • We tell lies to one another every day. But when we commit other acts that are generally believed to be immoral, like cruelty and theft, we do not seek to justify them. We either deny that the acts we committed are appropriately described by these terms, or we feel guilt or remorse. But many of us are prepared to defend our lies: indeed, to advocate their general use.
  • Nevertheless, it is my claim that we could not lead our lives if we never told lies — or that if we could it would be a much worse life. But I would like to invite your own views on this to begin a dialog. Here is a list of lies that I believe to be either permissible, or, in some cases, obligatory. Readers will certainly disagree with me about some, perhaps many, of these cases. But such disagreement should not be the end of the discussion. I invite your reflection on why you disagree.
