Cancer Studies Are Fatally Flawed. Meet the Young Billionaire Who's Exposing the Truth ... - 0 views

  • 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.

Let's Abolish Social Science | The Smart Set - 2 views

  • Social science was — it is best to speak in the past tense — a mistake. The dream of a comprehensive science of society, which would elucidate “laws of history” or “social laws” comparable to the physical determinants or “laws” of nature, was one of the great delusions of the 19th century.
  • Economics, for example, grew ever more pseudoscientific in the course of the 20th century.
  • The very term “political science” betrays an ambition to create a study of politics and government and world politics that will be a genuine science like physics, chemistry or biology.

  • The difference between the natural sciences and the humanities is the difference between motion and motive. Laws of motion can explain the trajectories of asteroids and atoms. The trajectories of human beings, like those of any animals with some degree of sentience, are explained by motives. Asteroids and atoms go where they have to go. Human beings go where they want to go.

Bruno Latour, the Post-Truth Philosopher, Mounts a Defense of Science - The New York Times - 0 views

  •  
    "Philosophers have traditionally recognized a division between facts and values - between, say, scientific knowledge on one hand and human judgments on the other. Latour believes that this is specious. Many of his books are attempts to illuminate, as he has written, "both the history of humans' involvement in the making of scientific facts and the sciences' involvement in the making of human history." In a formulation that was galling to both sociologists and scientists, he once argued that Louis Pasteur did not just, as is commonly accepted, discover microbes; rather, he collaborated with them."

Science Is Not Religion | Jeff Schweitzer - 3 views

  • Author Christine Ma-Kellams recently told HuffPost Science that, "In many ways, science seems like a 21st Century religion. It's a belief system that many wholeheartedly defend and evolve their lives around, sometimes as much as the devoutest of religious folk." Nothing could be further from the truth. Science is not a "belief system" but a process and methodology for seeking an objective reality. Of course because scientific exploration is a human endeavor it comes with all the flaws of humanity: ego, short-sightedness, corruption and greed. But unlike a "belief system" such as religion untethered to an objective truth, science is over time self-policing; competing scientists have a strong incentive to corroborate and build on the findings of others; but equally, to prove other scientists wrong by means that can be duplicated by others.

Science Isn't Broken | FiveThirtyEight - 0 views

  • If we’re going to rely on science as a means for reaching the truth — and it’s still the best tool we have — it’s important that we understand and respect just how difficult it is to get a rigorous result
  • Scientists’ overreliance on p-values has led at least one journal to decide it has had enough of them. In February, Basic and Applied Social Psychology announced that it will no longer publish p-values.
  • P-hacking and similar types of manipulations often arise from human biases. “You can do it in unconscious ways — I’ve done it in unconscious ways,” Simonsohn said. “You really believe your hypothesis and you get the data and there’s ambiguity about how to analyze it.” When the first analysis you try doesn’t spit out the result you want, you keep trying until you find one that does.

  • Science isn’t broken, nor is it untrustworthy. It’s just more difficult than most of us realize. We can apply more scrutiny to study designs and require more careful statistics and analytic methods, but that’s only a partial solution. To make science more reliable, we need to adjust our expectations of it.
  • From 2001 to 2009, the number of retractions issued in the scientific literature rose tenfold. It remains a matter of debate whether that’s because misconduct is increasing or is just easier to root out.
  • Science is not a magic wand that turns everything it touches to truth. Instead, “science operates as a procedure of uncertainty reduction,” said Nosek, of the Center for Open Science. “The goal is to get less wrong over time.”
  • Some of these biases are helpful, at least to a point. Take, for instance, naive realism — the idea that whatever belief you hold, you believe it because it’s true. This mindset is almost essential for doing science, quantum mechanics researcher Seth Lloyd of MIT told me. “You have to believe that whatever you’re working on right now is the solution to give you the energy and passion you need to work.” But hypotheses are usually incorrect, and when results overturn a beloved idea, a researcher must learn from the experience and keep, as Lloyd described it, “the hopeful notion that, ‘OK, maybe that idea wasn’t right, but this next one will be.’”

Can Brain Science Be Dangerous? - NYTimes.com - 2 views

  • The idea that poverty can change the brain has gotten significant attention recently, and not just from those lay readers (a minority, according to recent research) who spend a lot of time thinking about neuroscience. Policy makers and others have begun to apply neuroscientific principles to their thinking about poverty — and some say this could end up harming poor people rather than helping. At The Conversation, the sociologist Susan Sered takes issue with “news reports with headlines like this one: ‘Can Brain Science Help Lift People Out Of Poverty?’” She’s referring to a June story by Rachel Zimmerman at WBUR, about a nonprofit called Crittenton Women’s Union that aims to use neuroscience to help get people out of poverty. Elisabeth Babcock, Crittenton’s chief executive, tells Ms. Zimmerman: “What the new brain science says is that the stresses created by living in poverty often work against us, make it harder for our brains to find the best solutions to our problems. This is a part of the reason why poverty is so ‘sticky.’”
  • “The new neuroscience offers wonderful possibilities regarding Alzheimer’s disease, epilepsy, brain injuries and much more,” writes Dr. Sered. “But scientific knowledge always develops and is utilized within social contexts.” She and others fear that, used incorrectly, neuroscience might spread the view that poor people are lesser than others, that they are irrevocably debilitated by their experiences with poverty — or, conversely, that if they fail to respond to programs that science says will help them, it must be their own fault.
  • Ms. Williams writes that many of today’s child-development ideas are very similar to those of the psychiatrist John Bowlby’s work on attachment theory. But, she notes, he developed his ideas through psychological observation, not brain scans. And she quotes Sebastian Kraemer, a psychiatrist: “If John Bowlby were alive today, he would say, this [neuroscience] does not add anything. People are just more persuaded by it, by the facts and the pictures.” People do seem to find neuroscience extremely persuasive, even when it’s wrong. And this may be part of what critics fear — that images and facts about the brain are so powerful, they can make us believe things we really shouldn’t.

Imitation is what makes us human and creative - Kat McGowan - Aeon - 3 views

  • Throughout human history, innovation – including the technological progress we cherish – has been fuelled and sustained by imitation. Copying is the mighty force that has allowed the human race to move from stone knives to remote-guided drones, from digging sticks to crops that manufacture their own pesticides.

  • Lots of copying means that many minds get their chance at the problem; imitation ‘makes the contents of brains available to everyone’, writes the developmental psychologist Michael Tomasello in the Cultural Origins of Human Cognition (1999). Tomasello, who is co-director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, calls the combination of imitation and innovation the ‘cultural ratchet’. It is like a mechanical ratchet that permits motion in only one direction – such as winding a watch, or walking through a turnstile. Good ideas push the ratchet forward one notch. Faithful imitation keeps the ratchet from slipping backward, protecting ideas from being forgotten or lost and keeping knowledge alive for the next round of improvement.

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.

How a Gay-Marriage Study Went Wrong - The New Yorker - 1 views

  • ast December, Science published a provocative paper about political persuasion. Persuasion is famously difficult: study after study—not to mention much of world history—has shown that, when it comes to controversial subjects, people rarely change their minds, especially if those subjects are important to them. You may think that you’ve made a convincing argument about gun control, but your crabby uncle isn’t likely to switch sides in the debate. Beliefs are sticky, and hardly any approach, no matter how logical it may be, can change that. The Science study, “When contact changes minds: An experiment on transmission of support for gay equality,” seemed to offer a method that could work.
  • In the document, “Irregularities in LaCour (2014),” Broockman, along with a fellow graduate student, Joshua Kalla, and a professor at Yale, Peter Aronow, argued that the survey data in the study showed multiple statistical irregularities and was likely “not collected as described.”
  • If, in the end, the data do turn out to be fraudulent, does that say anything about social science as a whole? On some level, the case would be a statistical fluke. Despite what news headlines would have you believe, outright fraud is incredibly rare; almost no one commits it, and almost no one experiences it firsthand. As a result, innocence is presumed, and the mindset is one of trust.

  • There’s another issue at play: the nature of belief. As I’ve written before, we are far quicker to believe things that mesh with our view of how life should be. Green is a firm supporter of gay marriage, and that may have made him especially pleased about the study. (Did it have a similar effect on liberally minded reviewers at Science? We know that studies confirming liberal thinking sometimes get a pass where ones challenging those ideas might get killed in review; the same effect may have made journalists more excited about covering the results.)
  • In short, confirmation bias—which is especially powerful when we think about social issues—may have made the study’s shakiness easier to overlook.

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.

Problems Too Disgusting to Solve - The New Yorker - 0 views

  • last month, Bill Gates released a video of one of the latest ventures funded by the Bill and Melinda Gates Foundation: the Omniprocessor, a Seattle-based processing plant that burns sewage to make clean drinking water. In the video, Gates raises a glass of water to his lips. Just five minutes ago, the caption explains, that water was human waste. Gates takes a sip. “It’s water,” he says. “Having studied the engineering behind it,” he writes, on the foundation’s blog, “I would happily drink it every day. It’s that safe.”
  • In the first series of studies, the group asked adults in five cities about their backgrounds, their political and personal views, and, most important, their view on the concept of “recycled water.” On average, everyone was uncomfortable with the idea—even when they were told that treated, recycled water is actually safer to drink than unfiltered tap water. That discomfort, Rozin found, was all about disgust. Twenty-six per cent of participants were so disgusted by the idea of toilet-to-tap that they even agreed with the statement, “It is impossible for recycled water to be treated to a high enough quality that I would want to use it.” They didn’t care what the safety data said. Their guts told them that the water would never be drinkable. It’s a phenomenon known as contagion, or, as Rozin describes it, “once in contact, always in contact.” By touching something we find disgusting, a previously neutral or even well-liked item can acquire—permanently—its properties of grossness.
  • eelings of disgust are often immune to rationality. And with good reason: evolutionarily, disgust is an incredibly adaptive, life-saving reaction. We find certain things instinctively gross because they really can harm us. Human secretions pass on disease. Noxious odors signal that your surroundings may be unsafe. If something feels slimy and sludgy, it’s likely a moisture-rich environment where pathogens may proliferate. Disgust is powerful, in short, because it often signals something important. It’s easy, though, to be disgusted by things that aren’t actually dangerous. In a prior study, Rozin found that people were unwilling to drink a favorite beverage into which a “fully sterilized” cockroach had been dipped. Intellectually, they knew that the drink was safe, but they couldn’t get over the hump of disgust. In another experiment, students wouldn’t eat chocolate that had been molded to look like poop: they knew that it was safe—tasty, even—but its appearance was too much to handle. Their response makes no logical sense. When it comes to recycled water, for instance, Rozin points out that, on some level, all water comes from sewage: “Rain is water that used to be in someone’s toilet, and nobody seems to mind.” The problem, he says, has to do with making the hidden visible. “If it’s obvious—take shit water, put it through a filter—then people are upset.”

  • Disgust has deep psychological roots, emerging early in a child’s development. Infants and young toddlers don’t feel grossed out by anything—diapers, Rozin observes, are there in part to stop a baby “from eating her shit.” In the young mind, curiosity and exploration often overpower any competing instincts. But, at around four years old, there seems to be a profound shift. Suddenly, children won’t touch things that they find appalling. Some substances, especially human excretions of any sort, are seen as gross and untouchable all over the world; others are culturally determined. But, whether universal or culturally-specific, the disgust reactions that we acquire as children stay with us throughout our lives. If anything, they grow stronger—and more consequential—with age.

The Moral Instinct - New York Times - 1 views

  • “Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them,” wrote Immanuel Kant, “the starry heavens above and the moral law within.” These days, the moral law within is being viewed with increasing awe, if not always admiration. The human moral sense turns out to be an organ of considerable complexity, with quirks that reflect its evolutionary history and its neurobiological foundations. These quirks are bound to have implications for the human predicament. Morality is not just any old topic in psychology but close to our conception of the meaning of life. Moral goodness is what gives each of us the sense that we are worthy human beings. We seek it in our friends and mates, nurture it in our children, advance it in our politics and justify it with our religions. A disrespect for morality is blamed for everyday sins and history’s worst atrocities. To carry this weight, the concept of morality would have to be bigger than any of us and outside all of us. So dissecting moral intuitions is no small matter. If morality is a mere trick of the brain, some may fear, our very grounds for being moral could be eroded. Yet as we shall see, the science of the moral sense can instead be seen as a way to strengthen those grounds, by clarifying what morality is and how it should steer our actions.

There Is No Theory of Everything - The New York Times - 0 views

  • Despite the astonishing breadth of his interests, Frank’s core obsession in teaching turned on the relation between science and the humanities. More particularly, his concern was with the relation between the causal explanations offered by science and the kinds of humanistic description we find, say, in the novels of Dickens or Dostoevsky, or in the sociological writings of Erving Goffman and David Riesman. His quest was to try and clarify the occasions when a scientific explanation was appropriate and when it was not, and we need instead a humanistic remark. His conviction was that our confusions about science and the humanities had wide-ranging and malign societal consequences.

The New Science of Mind - NYTimes.com - 0 views

  •  
    This new science of mind is based on the principle that our mind and our brain are inseparable. The brain is a complex biological organ possessing immense computational capability: it constructs our sensory experience, regulates our thoughts and emotions, and controls our actions. It is responsible not only for relatively simple motor behaviors like running and eating, but also for complex acts that we consider quintessentially human, like thinking, speaking and creating works of art. Looked at from this perspective, our mind is a set of operations carried out by our brain. The same principle of unity applies to mental disorders.

Why Americans Are the Weirdest People in the World - 1 views

  • Henrich’s work with the ultimatum game was an example of a small but growing countertrend in the social sciences, one in which researchers look straight at the question of how deeply culture shapes human cognition. His new colleagues in the psychology department, Heine and Norenzayan, were also part of this trend. Heine focused on the different ways people in Western and Eastern cultures perceived the world, reasoned, and understood themselves in relationship to others. Norenzayan’s research focused on the ways religious belief influenced bonding and behavior. The three began to compile examples of cross-cultural research that, like Henrich’s work with the Machiguenga, challenged long-held assumptions of human psychological universality.
  • As Heine, Norenzayan, and Henrich furthered their search, they began to find research suggesting wide cultural differences almost everywhere they looked: in spatial reasoning, the way we infer the motivations of others, categorization, moral reasoning, the boundaries between the self and others, and other arenas. These differences, they believed, were not genetic. The distinct ways Americans and Machiguengans played the ultimatum game, for instance, wasn’t because they had differently evolved brains. Rather, Americans, without fully realizing it, were manifesting a psychological tendency shared with people in other industrialized countries that had been refined and handed down through thousands of generations in ever more complex market economies. When people are constantly doing business with strangers, it helps when they have the desire to go out of their way (with a lawsuit, a call to the Better Business Bureau, or a bad Yelp review) when they feel cheated. Because Machiguengan culture had a different history, their gut feeling about what was fair was distinctly their own. In the small-scale societies with a strong culture of gift-giving, yet another conception of fairness prevailed. There, generous financial offers were turned down because people’s minds had been shaped by a cultural norm that taught them that the acceptance of generous gifts brought burdensome obligations. Our economies hadn’t been shaped by our sense of fairness; it was the other way around.
  • Studies show that Western urban children grow up so closed off in man-made environments that their brains never form a deep or complex connection to the natural world. While studying children from the U.S., researchers have suggested a developmental timeline for what is called “folkbiological reasoning.” These studies posit that it is not until children are around 7 years old that they stop projecting human qualities onto animals and begin to understand that humans are one animal among many. Compared to Yucatec Maya communities in Mexico, however, Western urban children appear to be developmentally delayed in this regard. Children who grow up constantly interacting with the natural world are much less likely to anthropomorphize other living things into late childhood.

The Dangers of Certainty: A Lesson From Auschwitz - NYTimes.com - 1 views

  • The ascent of man was secured through scientific creativity. But unlike many of his more glossy and glib contemporary epigones, Dr. Bronowski was never reductive in his commitment to science. Scientific activity was always linked to artistic creation. For Bronowski, science and art were two neighboring mighty rivers that flowed from a common source: the human imagination. Newton and Shakespeare, Darwin and Coleridge, Einstein and Braque: all were interdependent facets of the human mind and constituted what was best and most noble about the human adventure.
  • For Dr. Bronowski, the moral consequence of knowledge is that we must never judge others on the basis of some absolute, God-like conception of certainty.
  • At this point, in the final minutes of the show, the scene suddenly shifts to Auschwitz, where many members of Bronowski’s family were murdered. Then this happened. Please stay with it. This short video from the show lasts only four minutes or so.[Video: Dr. Jacob Bronowski's argument against certainty, made at Auschwitz for his show "The Ascent of Man." Watch on YouTube.]It is, I am sure you agree, an extraordinary and moving moment. Bronowski dips his hand into the muddy water of a pond which contained the remains of his family members and the members of countless other families. All victims of the same hatred: the hatred of the other human being. By contrast, he says — just before the camera hauntingly cuts to slow motion — “We have to touch people.”

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.

The Science of Why We Don't Believe Science | Mother Jones - 0 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."
  • 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. We apply fight-or-flight reflexes not only to predators, but to data itself. We're not driven only by emotions, of course—we also reason, deliberate. But reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.
  • In other words, when we think we're reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we're being scientists, but we're actually being lawyers

  • A key question—and one that's difficult to answer—is how "irrational" all this is. On the one hand, it doesn't make sense to discard an entire belief system, built up over a lifetime, because of some new snippet of information.
  • Okay, so people gravitate toward information that confirms what they believe, and they select sources that deliver it. Same as it ever was, right? Maybe, but the problem is arguably growing more acute, given the way we now consume information—through the Facebook links of friends, or tweets that lack nuance or context, or "narrowcast" and often highly ideological media that have relatively small, like-minded audiences. Those basic human survival skills of ours, says Michigan's Arthur Lupia, are "not well-adapted to our information age."
