Millennials are losing their religion-and social media might explain why - Quartz - 0 views

  • American millennials—those born between 1982 and 1999—are less likely to identify as religious than previous generations at the same age, according to a new analysis of a combined large survey.
  • Though the survey results can only show correlation, and not causation, Twenge thinks that this generational shift is likely a result of a rise of individualism. “Individualism can be an uncomfortable fit with religion,” she says. Whereas religion typically emphasizes social norms and appeals to a higher authority, individualism focuses on the self and personal choices.
  • Researchers analyzed survey data from more than 11 million respondents, consisting of everyone from eighth graders to college-goers in the period between 1966 and 2014. The analysis, published in the journal PLOS One, reveals that even though the majority of adolescents still identify as religious in some way, a growing number is identifying as having no religion.

  • The need to belong hasn’t changed. What has changed is how people fulfill it. Now there’s the option to turn to things like Facebook, for example, rather than an external religious group, to find a community.

Innovation and equity in an age of gene editing | Science | The Guardian - 1 views

  • “A Gathering of Global Thought Leaders to Reach Consensus on the Direction of Biotechnology for the 21st Century”, in Atlanta, coincided with the announcement by the National Academy of Science and National Academy of Medicine of an initiative to look into “promising new treatments for disease,” given that “recent experiments to attempt to edit human genes also have raised important questions about the potential risks and ethical concerns of altering the human germline.”
  • On the other hand, there were others in the room, ourselves included, who argue in our work that “promising new treatments for disease” should not be pre-emptively morally centered, as to do so leaves out too many of the ethical issues at stake. As we pursue promising treatments, we should also be asking what we are trying to treat; whether it is best treated biomedically; who is included as funders, patients, donors, and scientists; who is left out; who profits; and whether or not the treatment masks, depoliticizes, or exacerbates political and social inequality.
  • Yesterday’s National Academies framing morally centered “promising new treatments for disease” and pitted “risks and ethical concerns” against those potential treatments.

  • Many of the worlds’ greatest medical challenges stem from poverty, inequality, discrimination, pollution, and environmental devastation, as critical race, gender, and decolonization scholars have shown us.
  • Let’s be alert to the ways in which risks and ethical issues present themselves at every stage of developing and implementing promising new treatments. Scientists themselves do not have to do this work. That is what social scientists do.

Organizational Success and Culture | Great Work Cultures - 0 views

  • Despite his best efforts, none of his business ventures ever achieved any commercial success, but his journey sparked in me an immense desire to understand how successful businesses are structured and managed. What I have come to appreciate is that no management structure or style is certain to result in business success but organizational cultures that encourage initiative, innovation and creativity are more effective than those cultures based on control.
  • He adopted a command and control management structure coupled with a patriarchal management style to operate his business. I don't think this was an intentional decision but like many new and less experienced entrepreneurs, organizational culture isn't usually a factor considered by the entrepreneur when determining how to build a successful enterprise. Instead, organizational cultures are often a byproduct of necessity driven by the demands of the business coupled with the leader's personal value system.
  • It is commonplace for leaders to choose management structures and styles that align with their own value systems. Like my father, many leaders possess a value system where the person at the top makes all the decisions and everyone else has to simply conform or risk losing their job.
  • ...3 more annotations...
  • In these cultures, leaders are fearful of losing their livelihood and use the same fear to lead their employees. So, it is not surprising that so many of us have experienced unjust and inequitable working conditions in command and control cultures where leaders use fear and aggression as the means to drive employee productivity.
  • Eventually, the very thing she was trying to protect, her livelihood, was lost. Would she have saved her own job had she opted for a different organizational structure or a nicer management style?
  • Though, historically, the command and control management structure and its many iterations of management styles has been successfully used by many companies, there is evidence that organizational cultures based on value systems that reward initiative, creativity and innovation result in greater employee productivity, loyalty and engagement than cultures based on control. In other words, organization's that adopt command and control management structures, even when coupled with friendlier management styles, are likely to find that employee productivity, engagement and loyalty are not as high as those organizational cultures that encourage initiative, creativity and innovation.

How Technology Can Help Language Learning | Suren Ramasubbu - 0 views

  • Intelligence, according to Gardner, is of eight types - verbal-linguistic, logical-mathematical, musical-rhythmic, visual-spatial, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic; existential and moral intelligence were added as afterthoughts in the definition of Intelligence. This is the first in a series of posts that explore and understand how each of the above forms of intelligence is affected by technology-mediated education.
  • Verbal-linguistic Intelligence involves sensitivity to spoken and written language, the ability to learn languages, and the capacity to use language to accomplish goals. Such intelligence is fostered by three specific activities: reading, writing and interpersonal communication - both written and oral.
  • Technology allows addition of multisensory elements that provide meaningful contexts to facilitate comprehension, thus expanding the learning ground of language and linguistics.
  • ...8 more annotations...
  • Research into the effect of technology on the development of the language and literacy skills vis-à-vis reading activities of children has offered evidence for favorable effects of digital-form books.
  • E-books are also being increasingly used to teach reading among beginners and children with reading difficulties.
  • Technology can be used to improve reading ability in many ways. It can enhance and sustain the interest levels for digitial natives by allowing immediate feedback on performance and providing added practice when necessary.
  • Technology can also help in improvement of writing skills. Word processing software promotes not only composition but also editing and revising in ways that streamline the task of writing.
  • However, the web cannot be discounted as being "bad for language", considering that it also offers very useful tools such as blogging and microblogging that can help the student improve her writing skills with dynamic feedback. The possibility of incorporating other media into a written document (e.g. figures, graphics, videos etc.) can enhance the joy of writing using technology.
  • Technology enhanced oral communication is indeed useful in that it allows students from remote locations, or from all over the world to communicate orally through video and audio conferencing tools.
  • As with anything to do with technology, there are also detractors who propose negative influence of features like animation, sound, music and other multimedia effects possible in digital media, which may distract young readers from the story content.
  • Such complaints notwithstanding, the symbiotic ties between linguistics and technology cannot be ignored.

How Scientists Engage the Public | Pew Research Center - 0 views

  • American scientists believe they face a challenging environment and the vast majority of them support the idea that participation in policy debates and engagement with citizens and journalists is necessary to further their work and careers.
  • A survey of 3,748 American-based scientists connected with the American Association for the Advancement of Science (AAAS) finds that 87% agree with the statement “Scientists should take an active role in public policy debates about issues related to science and technology.”
  • These findings come at a time when science topics are increasingly part of the public debate. Pew Research findings from this survey reported last month showed an overall drop among AAAS scientists in how they rate the state of science in general and their particular scientific field. Scientists also express concerns about the precarious state of research funding, some of the influences on how funding is allocated, and difficulties they feel hinder the capacity of science disciplines to attract the best talent to the field.
  • ...2 more annotations...
  • Nearly all the AAAS scientists (98%) say they have some level of interaction with citizens at least from time to time, and 51% have at least some contact with reporters about research findings. In addition, nearly half of AAAS scientists – 47% – use social media to talk about science or read about scientific developments at least some of the time.
  • The scientists who are most likely to be involved in public activities show distinct patterns by age, by the level of public debate and public interest they perceive in their specialty, and by discipline. Virtually all scientists engage with citizens. Mid-career and older scientists are especially likely to speak to reporters. Younger scientists are more likely to use social media. And blogging is something that equally spans the generations under age 65.

Researchers Link Feelings Of Disgust And Ethical Behavior : NPR - 0 views

  • Next, we examine what happens when you feel disgusted. Maybe you've come across rotting food or a bathroom that's dirty. Well, there's new research exploring how that kind of experience affects the ethical choices you might make afterward.
  • Disgust seems to make people behave in more unethical ways, Steve. This is research by Karen Winterich, Vikas Mittal and Andrea Morales. They conducted a series of experiments. In one of them, they had volunteers view a scene from the movie "Trainspotting," and the movie showed a disgustingly dirty toilet. Other volunteers watched a documentary about a coral reef. The researchers find that volunteers who watched the disgusting scene are more likely to cheat a partner in a game they play right afterwards.
  • And they're arguing that the feeling of disgust triggers feelings of self-preservation - wanting to protect yourself from the thing that's disgusting. And the researchers are speculating that these feelings of self-preservation translate more generally into feelings of selfishness, of looking out for yourself and this produces a willingness to cheat.
  • ...1 more annotation...
  • But it's another example of this mountain of studies that suggest that the social context in the social world changes our behavior even when we're not aware of it.

Children used to be scared of the dark - now they fear failure | Life and style | The G... - 0 views

  • I recently asked one of my youngest daughters what she feared most. She answered without hesitation: failure. This disturbed and surprised me. I had always thought of fear of failure as an adult preoccupation, but it seems that one of the effects of the climate of the times (and the media saturation that expresses it) is the importation of adult fears to childish minds. The fear of ghosts is being replaced by the terror of underperformance.
  • In this survey, from Johns Hopkins University in Baltimore, the top five fears 30 years ago were animals, being in a dark room, high places, strangers and loud noises. In the updated survey, kids were afraid of divorce, nuclear war, cancer, pollution, and being mugged.
  • Children’s fears are a litmus test of the society we live in and they are clearly changing – becoming more concrete – as society becomes more performance-driven, insecure and saturated with threatening, upsetting facts.

Who's to blame when fake science gets published? - 1 views

  • The now-discredited study got headlines because it offered hope. It seemed to prove that our sense of empathy, our basic humanity, could overcome prejudice and bridge seemingly irreconcilable differences. It was heartwarming, and it was utter bunkum. The good news is that this particular case of scientific fraud isn't going to do much damage to anyone but the people who concocted and published the study. The bad news is that the alleged deception is a symptom of a weakness at the heart of the scientific establishment.
  • When it was published in Science magazine last December, the research attracted academic as well as media attention; it seemed to provide solid evidence that increasing contact between minority and majority groups could reduce prejudice.
  • But in May, other researchers tried to reproduce the study using the same methods, and failed. Upon closer examination, they uncovered a number of devastating "irregularities" - statistical quirks and troubling patterns - that strongly implied that the whole LaCour/Green study was based upon made-up data.
  • ...6 more annotations...
  • The data hit the fan, at which point Green distanced himself from the survey and called for the Science article to be retracted. The professor even told Retraction Watch, the website that broke the story, that all he'd really done was help LaCour write up the findings.
  • Science magazine didn't shoulder any blame, either. In a statement, editor in chief Marcia McNutt said the magazine was essentially helpless against the depredations of a clever hoaxer: "No peer review process is perfect, and in fact it is very difficult for peer reviewers to detect artful fraud."
  • This is, unfortunately, accurate. In a scientific collaboration, a smart grad student can pull the wool over his adviser's eyes - or vice versa. And if close collaborators aren't going to catch the problem, it's no surprise that outside reviewers dragooned into critiquing the research for a journal won't catch it either. A modern science article rests on a foundation of trust.
  • If the process can't catch such obvious fraud - a hoax the perpetrators probably thought wouldn't work - it's no wonder that so many scientists feel emboldened to sneak a plagiarised passage or two past the gatekeepers.
  • Major peer-review journals tend to accept big, surprising, headline-grabbing results when those are precisely the ones that are most likely to be wrong.
  • Despite the artful passing of the buck by LaCour's senior colleague and the editors of Science magazine, affairs like this are seldom truly the product of a single dishonest grad student. Scientific publishers and veteran scientists - even when they don't take an active part in deception - must recognise that they are ultimately responsible for the culture producing the steady drip-drip-drip of falsification, exaggeration and outright fabrication eroding the discipline they serve.

Beware Eurosceptic versions of history and science| Rebekah Higgitt | Science | The Gua... - 1 views

  • Readers of the Guardian Science pages may not have noticed the group called Historians for Britain, or a recent piece in History Today by David Abulafia asserting their belief “that Britain’s unique history sets it apart from the rest of Europe”.
  • It requires critical scrutiny from everyone with an interest in Britain’s relationship with the rest of the world, and in evidence-based political discussion.
  • Abilafia’s article is a classic example of an old-fashioned “Whiggish” narrative. It claims a uniquely moderate and progressive advance toward the development of British institutions, traced continuously from Magna Carta and isolated from the rages and radicalism of the Continent.
  • ...3 more annotations...
  • The answer is not “because Britain is better and unique” but “because I am British and these are the stories I have been brought up on” at school, university, on TV and elsewhere. Go to another country and you will see that they have their own, equally admirable, pantheon of greats.
  • The area that I have been working on, the eighteenth-century search for longitude, likewise reveals the need to challenge nationalistic assumptions.
  • Historians and readers of history both need to be aware of the biases of our education and literature. Accounts of British exceptionalism, especially those that lump the rest of Europe or the world into an amorphous group of also-rans, are more the result of national tradition and wishful thinking than a careful reading of the sources.

How have changes to publishing affected scientists? | Julie McDougall-Waters | Science ... - 0 views

  • That was the purpose of a recent oral history event at the Royal Society, involving four senior scientists who began their careers in the 1960s and 1970s. Rather than simply reminiscing, they were asked to recall their publishing experiences in scientific periodicals over the last fifty years. How have things changed since they published their first paper?
  • It became clear that the hierarchy of journals has changed over the last fifty years, and the pressure to publish in those considered to have the highest impact has increased considerably, partly a result of the increased volume of data being produced and the need for readers to filter relevant information from the copious amounts of less pertinent stuff available.
  • What have also changed are the technologies available to write a paper. Frith related the process she went through in writing her first paper: “I wrote my papers by long hand and then typed them myself.” Writing a biological paper before computers is one thing, but Ashmore remembered the problems of producing mathematical formulae in a typed manuscript, explaining that “you wrote the paper and probably took it along to somebody to be typed… And then it came back with spaces where you had to write in the equations.”
  • ...2 more annotations...
  • Another change that interested the panellists was the increased number of collaborative and multiple authored papers now submitted to journals, which led them to think about the ethics of acknowledgement. In Meurig Thomas’s view the author is, simply, “the person that primarily thinks about the experiment, plans it, and writes it. I can sleep more comfortably at night this way. If I claim to be a senior author, I have to write it and I have to concoct what the experiment was, and defend it.” Chaloner suggested that authorship has grown “because of the pressure for people to have publications in their names”, with an “agreement to let you come onto this paper and I’ll get on yours next time”. Frith referred to this as “gaming”.
  • Despite all of the technological developments in the last fifty years, there has been no quick or easy response to questions over refereeing, and the event ended with the feeling that although there is no doubt technology has transformed the way science is communicated, its effect has not invariably simplified the process.

Do you see what I see? | The Economist - 0 views

  • HUMAN beings are not born with the knowledge that others possess minds with different contents. Children develop such a “theory of mind” gradually, and even adults have it only imperfectly. But a study by Samantha Fan and Zoe Liberman at the University of Chicago, published in Psychological Science, finds that bilingual children, and also those simply exposed to another language on a regular basis, have an edge at the business of getting inside others’ minds.
  • This study joins a heap of others suggesting that there are cognitive advantages to being bilingual. Researchers have found that bilinguals have better executive function (control over attention and the planning of complex tasks). Those that suffer dementia begin to do so, on average, almost five years later than monolinguals. Full bilinguals had previously been shown to have better theory-of-mind skills. But this experiment is the first to demonstrate that such benefits also accrue to those merely exposed to other languages.
  • It has become fashionable to consider multilingualism as a kind of elite mental training. The question is not settled, though, for many studies have not been successfully replicated. Nor is it yet clear precisely which kinds of language skills and exposure make people better at exactly which tasks.
  • ...1 more annotation...
  • While some advantages, such as lack of dementia, appear late in life, others may appear early only to disappear thereafter. Research on multilingual minds is, itself, still in a kind of adolescence, but it is a promising one

How can we best assess the neuropsychological effects of violent video game play? | Pet... - 0 views

  • Every time a research paper about violent video games makes it into the news, it feels like we’re in a time loop. Any claims that the study makes about the potential positive or (usually) negative effects of playing games tend to get over-egged to the point of ridiculousness.
  • At best, the measures of aggression that are used in such work are unstandardised; at worst, the field has been shown to be riddled with basic methodological and analytical flaws. These problems are further compounded by entrenched ideologies and a reluctance from some researchers to even talk to their ‘adversaries’, let alone discuss the potential for adversarial collaborations
  • All of this means that we’re stuck at an impasse with violent video games research; it feels like we’re no more clued up on what the actual behavioural effects are now than, say, five or ten years ago.
  • ...4 more annotations...
  • In stage 1, they submit the introduction, methods, proposed analysis, and if necessary, pilot data. This manuscript then goes through the usual peer review process, and is assessed on criteria such as the soundness of the methods and analysis, and overall plausibility of the stated hypotheses.
  • Once researchers have passed through stage 1, they can then move on to data collection. In stage 2, they then submit the full manuscript – the introduction and agreed methods from stage 1, plus results and discussion sections. The results must include the outcome of the analyses agreed in stage 1, but the researchers are allowed to include additional analyses in a separate, ‘exploratory’ section (as long as they are justified).
  • Pre-registering scientific articles in this way helps to protect against a number of undesirable practices (such as p-hacking and HARKing) that can exaggerate statistical findings and make non-existent effects seem real. While this is a problem across psychology generally, it is a particularly extreme problem for violent video game research.
  • By outlining the intended methods and analysis protocols beforehand, Registered Reports protect against these problems, as the review process concentrates on the robustness of the proposed methods. And Registered Reports offer an additional advantage: because manuscripts are never accepted based on the outcome of the data analysis, the process is immune to researcher party lines. It doesn’t matter which research ‘camp’ you are in; your data – and just as importantly, your methods - will speak for themselves.

Gender and racial bias can be 'unlearnt' during sleep, new study suggests | Science | T... - 0 views

  • Now scientists have found a more noble purpose for the technique in a study that suggests deep-rooted biases about race and gender could be “unlearnt” during a short nap. The findings appear to confirm the idea that sleeping provides a unique window for accessing and altering fundamental beliefs – even prejudices that we don’t know we have.
  • Simply playing auditory cues while people slept partially undid racial and gender bias, the study found, and the effects were still evident at least a week later.
  • “These biases are well-learned,” said Hu. “They can operate efficiently even when we have the good intention to avoid such biases. Moreover, we are often not aware of their influences on our behaviour.”
  • ...4 more annotations...
  • The study, published in Science, began with two Pavlovian-style conditioning exercises designed to counter race and gender biases.
  • However, they caution that the use of the technique in future would need strict ethical guidelines. “Sleep is a state in which the individual is without wilful consciousness and therefore vulnerable to suggestion,” they add.
  • Scientists believe the technique works because we consolidate memories by replaying them during sleep and transferring the information from the brain’s temporary storage to long-term memory. Hearing the distinctive sound would trigger the memory to be replayed repeatedly, the scientists said, enhancing the learning process.
  • “We call this Targeted Memory Reactivation, because the sounds played during sleep could produce relatively better memory for information cued during sleep compared to information not cued during sleep.

The Big Problem With the New SAT - NYTimes.com - 1 views

  • AT first glance, the College Board’s revised SAT seems a radical departure from the test’s original focus on students’ general ability or aptitude.
  • The revised SAT takes some important, if partial, steps toward becoming a test of curriculum mastery. In place of the infamously tricky, puzzle-type items, the exam will be a more straightforward test of material that students encounter in the classroom.
  • While a clear improvement, the revised SAT remains problematic. It will still emphasize speed — quick recall and time management — over subject knowledge. Despite evidence that writing is the single most important skill for success in college, the essay will be optional.
  • ...3 more annotations...
  • And the biggest problem is this: While the content will be new, the underlying design will not change. The SAT will remain a “norm-referenced” exam, designed primarily to rank students rather than measure what they actually know.
  • Norm-referenced tests like the SAT and the ACT have contributed enormously to the “educational arms race” — the ferocious competition for admission at top colleges and universities. They do so by exaggerating the importance of small differences in test scores that have only marginal relevance for later success in college. Because of the way such tests are designed, answering even a few more questions correctly can substantially raise students’ scores and thereby their rankings. This creates great pressure on students and their parents to avail themselves of expensive test-prep services in search of any edge. It is also unfair to those who cannot afford such services. Yet research on college admissions has repeatedly confirmed that test scores, as compared to high school grades, are relatively weak predictors of how students actually perform in college.
  • College admissions will never be perfectly fair and rational; the disparities are too deep for that. Yet the process can be fairer and more rational if we rethink the purposes of college-entrance exams.

Go to Sleep: It May Be the Best Way to Avoid Getting Alzheimer's | TIME - 0 views

  • “What we think we found is a new way that disruption of sleep contributes to the pathology that can disrupt the cementing of memories,” says Bryce Mander, a post doctoral fellow at University of California, Berkeley, and lead author of the paper. The findings also resolve one of the puzzling questions in Alzheimer’s disease: why buildup of amyloid starts initially in areas of the brain that don’t have anything to do with memory. Mander and Walker’s team found that the protein does deposit, however, in areas of the brain that generate the wave patterns of deep sleep.
  • The relationship between sleep and amyloid is likely a two-way street, they say, in which the more amyloid that builds up, the worse the sleep, and the more disrupted the sleep, the more amyloid that gets deposited. Other studies have shown that deep sleep can cement memories as well as clear away amyloid. Not getting enough deep sleep, then, perpetuates the poor memory cycle.
  • When the team studied 26 cognitively normal older adults, they found that higher amounts of amyloid, the protein responsible for the hallmark plaques found in Alzheimer’s disease, were linked with more disrupted deep sleep patterns.
  • ...2 more annotations...
  • Poor sleep may be contributing to the buildup of the brain plaques that drive the disease
  • “Sleep is a great early warning beacon, a distress call that we can latch onto, to potentially alert us to the beginnings of Alzheimer’s,” says Walker.

Teenagers Seek Health Information Online, but Don't Always Trust It - NYTimes.com - 1 views

When You Think Your Brain Is Doing Nothing, It's Really Getting You Ready To Socialize ... - 0 views

  • Your brain is always doing something. Even when you think it’s “offline” because you aren’t actively engaging a task or problem, your brain is busy reducing activity in some of its areas and increasing it in others.
  • A new study offers an answer that makes Facebook browsing suddenly seem more meaningful. The researchers believe that when the brain isn’t actively engaging a task, it drops into a mode that prepares it to be social with other brains.
  • We’ve discovered, however, that daydreaming is important default-mode time for the brain where different, less directly-active processing happens. This study suggests that part of this default-mode processing helps the brain prepare for social interaction with other brains.

  • According to Lieberman, “The brain has a major system that seems predisposed to get us ready to be social in our spare moments. The social nature of our brains is biologically based.”

Mice with 'amnesia' have memories restored by light - The Washington Post - 0 views

  • New research shows that "lost" memories lurk in the brain waiting to be found again -- in mice, anyway. In a study published Thursday in Science, researchers were able to reactivate memories they'd suppressed, indicating that retrograde amnesia -- where memories are lost after brain trauma -- may be more of a memory retrieval problem than an actual loss of data.
  • Based on their findings, the researchers believe that "lost" memories may still leave engrams active in the brain.
  • When they extended the search further, they realized that other regions of the brain, including the amygdala, where where fear-based memories can be found, were also involved in this network. The researchers were therefore able to retrieve the memories because other connections in the brain — connections that were unaffected by the drug, but inaccessible without the light treatment — were storing information related to the shock treatment as well.
  • ...2 more annotations...
  • "Our conclusion is that in retrograde amnesia, past memories may not be erased, but could simply be lost and inaccessible for recall," lead author Susumu Tonegawa, director of the RIKEN Brain Science Institute in Saitama, Japan, said in a statement. "These findings provide striking insight into the fleeting nature of memories, and will stimulate future research on the biology of memory and its clinical restoration."
  • "It's very difficult to be doing this in humans, partly for the ethical reasons — the work is invasive — but also because we tag the memories in the brain before they're learned," Tomas Ryan, a neuroscientist at MIT

Smarter Every Year? Mystery of the Rising IQs - WSJ - 0 views

  • That’s because absolute performance on IQ tests—the actual number of questions people get right—has greatly improved over the last 100 years. It’s called the Flynn effect, after James Flynn, a social scientist at New Zealand’s University of Otago who first noticed it in the 1980s.
  • They found that the Flynn effect is real—and large. The absolute scores consistently improved for children and adults, for developed and developing countries. People scored about three points more every decade, so the average score is 30 points higher than it was 100 years ago.
  • The pace jumped in the 1920s and slowed down during World War II. The scores shot up again in the postwar boom and then slowed down again in the ’70s. They’re still rising, but even more slowly. Adult scores climbed more than children’s.
  • ...5 more annotations...
  • Genes couldn’t change that swiftly, but better nutrition and health probably played a role. Still, that can’t explain why the change affected adults’ scores more than children’s. Economic prosperity helped, too—IQ increases correlate significantly with higher gross domestic product.
  • “Life history” is another promising theory. A longer period of childhood correlates with better learning abilities across many species.
  • The best explanation probably depends on some combination of factors. Dr. Flynn himself argues for a “social multiplier” theory. An initially small change can set off a benign circle that leads to big effects. Slightly better education, health, income or nutrition might make a child do better at school and appreciate learning more. That would motivate her to read more books and try to go to college, which would make her even smarter and more eager for education, and so on.
  • The fact that more people go to school for longer likely played the most important role—more education also correlates with IQ increases. That could explain why adults, who have more schooling, benefited most.
  • The thing that really makes humans so smart, throughout our history, may be that we can invent new kinds of intelligence to suit our changing environments.

Schoolroom Climate Change Indoctrination - WSJ - 0 views

  • While many American parents are angry about the Common Core educational standards and related student assessments in math and English, less attention is being paid to the federally driven green Common Core that is now being rolled out across the country. Under the guise of the first new K-12 science curriculum to be introduced in 15 years, the real goal seems to be to expose students to politically correct climate-change orthodoxy during their formative learning years.
  • The standards were designed to provide students with an internationally benchmarked science education.
  • From the council’s perspective, the science of climate change has already been settled. Not surprisingly, global climate change is one of the disciplinary core ideas embedded in the Next Generation of Science Standards, making it required learning for students in grade, middle and high school.
  • ...3 more annotations...
  • The National Research Council framework for K-12 science education recommends that by the end of Grade 5, students should appreciate that rising average global temperatures will affect the lives of all humans and other organisms on the planet. By Grade 8, students should understand that the release of greenhouse gases from burning fossil fuels is a major factor in global warming. And by Grade 12, students should know that global climate models are very effective in modeling, predicting and managing the current and future impact of climate change.
  • Relying on a climate-change curriculum and teaching materials largely sourced from federal agencies—particularly those of the current ideologically driven administration—raises a number of issues. Along with the undue authoritative weight that such government-produced documents carry in the classroom, most of the work is one-sided and presented in categorical terms, leaving no room for a balanced discussion. Moreover, too much blind trust is placed in the predictive power of long-range computer simulations, despite the weak forecasting track record of most climate models to date.
  • Employing such a Socratic approach to teaching climate change would likely lead to a rational and thought-provoking classroom debate on the merits of the case. However, that is not the point of this academic exercise—which seems to be to indoctrinate young people by using K-12 educators to establish the same positive political feedback loop around global warming that has existed between the federal government and the nation’s colleges and universities for the past two decades.
