Alyson McGregor: Why medicine often has dangerous side effects for women | TED Talk | T... - 0 views

  • For most of the past century, drugs approved and released to market have been tested only on male patients, leading to improper dosing and unacceptable side effects for women. The important physiological differences between men and women have only recently been taken into consideration in medical research. Emergency doctor Alyson McGregor studies these differences, and in this fascinating talk she discusses the history behind how the male model became our framework for medical research and how understanding differences between men and women can lead to more effective treatments for both sexes

BBC News - Astrologers look to the stars to help Indian businesses - 4 views

  • It is another busy day for Abhishek Dhawan in Delhi. His phone has not stopped ringing and he has a series of business meetings. Many of his business clients want to know when is the best time to release their products. Abhishek has been studying a number of factors and charts to try to help them. But he is not a marketing guru or an economist - he is an astrologer and he uses the position of the stars and the planets as a guide to help businesses maximise their profits.
  • When I ask Abhishek what his success rate is, he answers immediately. "Eighty per cent - this is like a science and when we make mistakes it is because people do not provide us with the correct information."

Female Scientists Turn to Data to Fight Lack of Representation on Panels - The New York... - 0 views

  • Among the defenders of the project, however, is Anne Churchland, a neuroscientist at Cold Spring Harbor Laboratory who studies how people make decisions. In 2001, she started Anne’s List, a directory of 170 women in computational neuroscience, intended to silence claims that no good female scientists existed in that field.Her research suggests that someone you recently had lunch with or someone from your hometown might spring to mind when selecting a speaker, even though neither has anything to do with science.“It doesn’t feel like irrelevant information influences our judgment, but it does,” Dr. Churchland said.

The Science of Why We Don't Believe Science - 2 views

  • "A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point." So wrote the celebrated Stanford University psychologist Leon Festinger [1] (PDF), in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes. But it was too early for that—this was the 1950s—and Festinger was actually describing a famous case study [2] in psychology. Festinger and several of his colleagues had infiltrated the Seekers, a small Chicago-area cult whose members thought they were communicating with aliens—including one, "Sananda," who they believed was the astral incarnation of Jesus Christ. The group was led by Dorothy Martin, a Dianetics devotee who transcribed the interstellar messages through automatic writing.
  • 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 [5]" 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 [6] (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.

Big Ideas in Social Science: An Interview With Steven Pinker on Violence and Human Nature - 1 views

  • I think most philosophers of science would say that all scientific generalizations are probabilistic rather than logically certain, more so for the social sciences because the systems you are studying are more complex than, say, molecules, and because there are fewer opportunities to intervene experimentally and to control every variable. But the exis­tence of the social sciences, including psychology, to the extent that they have discovered anything, shows that, despite the uncontrollability of human behavior, you can make some progress: you can do your best to control the nuisance variables that are not literally in your control; you can have analogues in a laboratory that simulate what you’re interested in and impose an experimental manipulation. You can be clever about squeezing the last drop of causal information out of a correlational data set, and you can use converging evi­dence, the qualitative narratives of traditional history in combination with quantitative data sets and regression analyses that try to find patterns in them. But I also go to traditional historical narratives, partly as a sanity check. If you’re just manipulating numbers, you never know whether you’ve wan­dered into some preposterous conclusion by taking numbers too seriously that couldn’t possibly reflect reality. Also, it’s the narrative history that provides hypotheses that can then be tested. Very often a historian comes up with some plausible causal story, and that gives the social scientists something to do in squeezing a story out of the numbers.

Muslim Boys at a Swiss School Must Shake Teachers' Hands, Even Female Ones - The New Yo... - 0 views

  • When two Syrian immigrant brothers refused to shake their female teacher’s hand this year, it ignited national outrage in Switzerland.This week, the authorities in the northern canton of Basel-Landschaft ruled that the students, who studied at a public school in the small town of Therwil, could not refuse to shake their teacher’s hand on religious grounds. They said that parents whose children refused to obey the longstanding tradition could be fined up to 5,000 Swiss francs, about $5,050.Shaking a teacher’s hand before and after class is part of Switzerland’s social fabric, and is considered an important sign of politeness and respect.

Mapping Where Gun Dealers Outnumber Starbucks in the U.S. - CityLab - 0 views

  •  
    "The Bureau of Alcohol, Tobacco, Firearms and Explosives reports that 64,747 licensed gun dealers (defined here as gun shops, pawnbrokers, or individual sellers) existed in the U.S. as of December 2015. But that raw number alone might not mean much to you. So a new mapping project by data viz company 1point21 Interactive tries to contextualize this number by comparing it to something all Americans know exists in abundance: Starbucks. "Looking at the Federal Firearms License data, the first question I asked myself was, 'Is that a lot-it sounds like a lot?'" Brian Beltz, who helped put the project together, tells CityLab. "That's why we chose to compare it to something that everyone knows and has a reputation of being on every corner." "

What's Behind Big Science Frauds? - NYTimes.com - 3 views

  • Remember that study showing vaccines were linked to autism? The time scientists claimed to have cloned human embryonic stem cells? Or that simple, easy way that was supposed to revolutionize the creation of such stem cells?Those were all frauds published in the world’s top scientific journals — The Lancet, Science and Nature. The vaccine scare has been associated with a surge in cases of measles, some of them deadly.Every day, on average, a scientific paper is retracted because of misconduct. Two percent of scientists admit to tinkering with their data in some kind of improper way. That number might appear small, but remember: Researchers publish some 2 million articles a year, often with taxpayer funding. In each of the last few years, the Office of Research Integrity, part of the United States Department of Health and Human Services, has sanctioned a dozen or so scientists for misconduct ranging from plagiarism to fabrication of results.

Fighting ISIS With an Algorithm, Physicists Try to Predict Attacks - The New York Times - 0 views

  • And with the Islamic State’s prolific use of social media, terrorism experts and government agencies continually search for clues in posts and Twitter messages that appear to promote the militants’ cause.A physicist may not seem like an obvious person to study such activity. But for months, Neil Johnson, a physicist at the University of Miami, led a team that created a mathematical model to sift order from the chaotic pro-terrorism online universe.
  • The tracking of terrorists on social media should take a cue from nature, Dr. Johnson said, where “the way transitions happen is like a flock of birds, a school of fish.”
  • The researchers also said there might be a spike in the formation of small online groups just before an attack takes place.

  • Both Mr. Berger and Ms. Patel noted a tricky question raised by the research: When is it best to try to suppress small groups so they do not mushroom into bigger groups, and when should they be left to percolate? Letting them exist for a while might be a way to gather intelligence, Ms. Patel said.

A Push for Diesel Leaves London Gasping Amid Record Pollution - The New York Times - 0 views

  • The current problem is, in part, an unintended consequence of previous efforts to aid the environment.The British government provided financial incentives to encourage a shift to diesel engines because laboratory tests suggested that would cut harmful emissions and combat climate change. Yet, it turned out that diesel cars emit on average five times as much emissions in real-world driving conditions as in the tests, according to a British Department for Transport study.

  • Like a number of up-and-coming researchers in his generation, Nosek was troubled by mounting evidence that science itself—through its systems of publication, funding, and advancement—had become biased toward generating a certain kind of finding: novel, attention grabbing, but ultimately unreliable. The incentives to produce positive results were so great, Nosek and others worried, that some scientists were simply locking their inconvenient data away.

Without Language, Large Numbers Don't Add Up : NPR - 0 views

  • A study of people in Nicaragua has concluded that humans need language in order to understand large numbers.
  • He says the brains of all people — and some animals — can tell the difference between, say, two cookies and three cookies on a plate. The human brain is also very good at assessing approximate values, like the difference between 10 and 20 cookies, Casasanto says. But he says the brain needs some sort of counting system to tell the difference between 10 cookies and 11. "What language does is give you a means of linking up our small, exact number abilities with our large, approximate number abilities," Casasanto says. And for people in developed countries, that's essential.

Why Teach and Study English? : The New Yorker - 0 views

  • The reward is that it remains the one kind of time travel that works, where you make a wish and actually become a musketeer in Paris or a used-car salesman in Pennsylvania. That one knows, of course, that the actuality is “fictional” or artificial doesn’t change its reality. The vicarious pleasure of reading is, by the perverse principle of professions, one that is often banished from official discussion, but it remains the core activity.
  • So: Why should English majors exist? Well, there really are no whys to such things, anymore than there are to why we wear clothes or paint good pictures or live in more than hovels and huts or send flowers to our beloved on their birthday. No sane person proposes or has ever proposed an entirely utilitarian, production-oriented view of human purpose. We cannot merely produce goods and services as efficiently as we can, sell them to each other as cheaply as possible, and die.

Why We Make Bad Decisions - NYTimes.com - 1 views

  • We need to be aware of our natural born optimism, for that harms good decision making, too. The neuroscientist Tali Sharot conducted a study in which she asked volunteers what they believed the chances were of various unpleasant events’ occurring — events like being robbed or developing Parkinson’s disease. She then told them what the real chances of such an event happening actually were. What she discovered was fascinating. When the volunteers were given information that was better than they hoped or expected — say, for example, that the risk of complications in surgery was only 10 percent when they thought it was 30 percent — they adjusted closer to the new risk percentages presented. But if it was worse, they tended to ignore this new information. This could explain why smokers often persist with smoking despite the overwhelming evidence that it’s bad for them. If their unconscious belief is that they won’t get lung cancer, for every warning from an antismoking campaigner, their brain is giving a lot more weight to that story of the 99-year-old lady who smokes 50 cigarettes a day but is still going strong.

Raising a Moral Child - NYTimes.com - 0 views

  • Genetic twin studies suggest that anywhere from a quarter to more than half of our propensity to be giving and caring is inherited. That leaves a lot of room for nurture, and the evidence on how parents raise kind and compassionate children flies in the face of what many of even the most well-intentioned parents do in praising good behavior, responding to bad behavior, and communicating their values.

How politics makes us stupid - Vox - 0 views

  • In April and May of 2013, Yale Law professor Dan Kahan — working with coauthors Ellen Peters, Erica Cantrell Dawson, and Paul Slovic — set out to test a question that continuously puzzles scientists: why isn’t good evidence more effective in resolving political debates? For instance, why doesn’t the mounting proof that climate change is a real threat persuade more skeptics?
  • The leading theory, Kahan and his coauthors wrote, is the Science Comprehension Thesis, which says the problem is that the public doesn’t know enough about science to judge the debate. It’s a version of the More Information Hypothesis: a smarter, better educated citizenry wouldn’t have all these problems reading the science and accepting its clear conclusion on climate change. But Kahan and his team had an alternative hypothesis. Perhaps people aren’t held back by a lack of knowledge. After all, they don’t typically doubt the findings of oceanographers or the existence of other galaxies. Perhaps there are some kinds of debates where people don’t want to find the right answer so much as they want to win the argument. Perhaps humans reason for purposes other than finding the truth — purposes like increasing their standing in their community, or ensuring they don’t piss off the leaders of their tribe. If this hypothesis proved true, then a smarter, better-educated citizenry wouldn’t put an end to these disagreements. It would just mean the participants are better equipped to argue for their own side.
  • Kahan doesn’t find it strange that we react to threatening information by mobilizing our intellectual artillery to destroy it. He thinks it’s strange that we would expect rational people to do anything else.

  • Kahan’s studies, depressing as they are, are also the source of his optimism: he thinks that if researchers can just develop a more evidence-based model of how people treat questions of science as questions of identity then scientists could craft a communications strategy that would avoid those pitfalls. "My hypothesis is we can use reason to identify the sources of the threats to our reason and then we can use our reason to devise methods to manage and control those processes," he says.
