  • YouTube said on Sunday that it was investigating the simmering complaints by some users that its family-friendly “restricted mode” wrongly filters out some lesbian, gay, bisexual and transgender videos.
  • In a statement, YouTube described restricted mode as “an optional feature used by a very small subset of users who want to have a more limited YouTube experience.”
  • In a statement, YouTube said that many videos featuring lesbian, gay, bisexual and transgender content were unaffected by the filter, an optional parental-control setting, and that it only targeted those that discussed sensitive topics such as politics, health and sexuality.

  • the system is “not 100 percent accurate.”
  • Over the weekend, many video creators and users complained on Twitter, recycling the hashtag #YouTubeIsOverParty, which was trending worldwide by Sunday night.

    Restriction in social media has always been a controversial issue. I think this problem in the system filtering the videos of gay and transgender creator shouldn't be all blamed on Youtube. I think the system Youtube used to filter the video is not based on the sexuality information of the creators. It think the system might take in the comments and survey results from the viewer. I think this reflects that the mainstream community and mindset still reject and repel transgenders and gays. People don't want to be sensitive topics. --Sissi (3/20/2017)

  • there are two very different phenomena at play here, each of which subvert the flow of information in very distinct ways. Let’s call them echo chambers and epistemic bubbles. Both are social structures that systematically exclude sources of information. Both exaggerate their members’ confidence in their beliefs.
  • they work in entirely different ways, and they require very different modes of intervention
  • An epistemic bubble is when you don’t hear people from the other side. An echo chamber is what happens when you don’t trust people from the other side.
  • ...90 more annotations...
  • start with epistemic bubbles
  • That omission might be purposeful
  • But that omission can also be entirely inadvertent. Even if we’re not actively trying to avoid disagreement, our Facebook friends tend to share our views and interests
  • An ‘echo chamber’ is a social structure from which other relevant voices have been actively discredited. Where an epistemic bubble merely omits contrary views, an echo chamber brings its members to actively distrust outsiders.
  • an echo chamber is something like a cult. A cult isolates its members by actively alienating them from any outside sources. Those outside are actively labelled as malignant and untrustworthy.
  • In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined.
  • The way to break an echo chamber is not to wave “the facts” in the faces of its members. It is to attack the echo chamber at its root and repair that broken trust.
  • Looking to others for corroboration is a basic method for checking whether one has reasoned well or badly
  • They have been in the limelight lately, most famously in Eli Pariser’s The Filter Bubble (2011) and Cass Sunstein’s #Republic: Divided Democracy in the Age of Social Media (2017).
  • The general gist: we get much of our news from Facebook feeds and similar sorts of social media. Our Facebook feed consists mostly of our friends and colleagues, the majority of whom share our own political and cultural views
  • various algorithms behind the scenes, such as those inside Google search, invisibly personalise our searches, making it more likely that we’ll see only what we want to see. These processes all impose filters on information.
  • Such filters aren’t necessarily bad. The world is overstuffed with information, and one can’t sort through it all by oneself: filters need to be outsourced.
  • That’s why we all depend on extended social networks to deliver us knowledge
  • any such informational network needs the right sort of broadness and variety to work
  • Each individual person in my network might be superbly reliable about her particular informational patch but, as an aggregate structure, my network lacks what Sanford Goldberg in his book Relying on Others (2010) calls ‘coverage-reliability’. It doesn’t deliver to me a sufficiently broad and representative coverage of all the relevant information.
  • Epistemic bubbles also threaten us with a second danger: excessive self-confidence.
  • An ‘epistemic bubble’ is an informational network from which relevant voices have been excluded by omission
  • Suppose that I believe that the Paleo diet is the greatest diet of all time. I assemble a Facebook group called ‘Great Health Facts!’ and fill it only with people who already believe that Paleo is the best diet. The fact that everybody in that group agrees with me about Paleo shouldn’t increase my confidence level one bit. They’re not mere copies – they actually might have reached their conclusions independently – but their agreement can be entirely explained by my method of selection.
  • Luckily, though, epistemic bubbles are easily shattered. We can pop an epistemic bubble simply by exposing its members to the information and arguments that they’ve missed.
  • echo chambers are a far more pernicious and robust phenomenon.
  • amieson and Cappella’s book is the first empirical study into how echo chambers function
  • echo chambers work by systematically alienating their members from all outside epistemic sources.
  • Their research centres on Rush Limbaugh, a wildly successful conservative firebrand in the United States, along with Fox News and related media
  • His constant attacks on the ‘mainstream media’ are attempts to discredit all other sources of knowledge. He systematically undermines the integrity of anybody who expresses any kind of contrary view.
  • outsiders are not simply mistaken – they are malicious, manipulative and actively working to destroy Limbaugh and his followers. The resulting worldview is one of deeply opposed force, an all-or-nothing war between good and evil
  • The result is a rather striking parallel to the techniques of emotional isolation typically practised in cult indoctrination
  • cult indoctrination involves new cult members being brought to distrust all non-cult members. This provides a social buffer against any attempts to extract the indoctrinated person from the cult.
  • The echo chamber doesn’t need any bad connectivity to function. Limbaugh’s followers have full access to outside sources of information
  • As Elijah Millgram argues in The Great Endarkenment (2015), modern knowledge depends on trusting long chains of experts. And no single person is in the position to check up on the reliability of every member of that chain
  • Their worldview can survive exposure to those outside voices because their belief system has prepared them for such intellectual onslaught.
  • exposure to contrary views could actually reinforce their views. Limbaugh might offer his followers a conspiracy theory: anybody who criticises him is doing it at the behest of a secret cabal of evil elites, which has already seized control of the mainstream media.
  • Perversely, exposure to outsiders with contrary views can thus increase echo-chamber members’ confidence in their insider sources, and hence their attachment to their worldview.
  • ‘evidential pre-emption’. What’s happening is a kind of intellectual judo, in which the power and enthusiasm of contrary voices are turned against those contrary voices through a carefully rigged internal structure of belief.
  • One might be tempted to think that the solution is just more intellectual autonomy. Echo chambers arise because we trust others too much, so the solution is to start thinking for ourselves.
  • that kind of radical intellectual autonomy is a pipe dream. If the philosophical study of knowledge has taught us anything in the past half-century, it is that we are irredeemably dependent on each other in almost every domain of knowledge
  • Limbaugh’s followers regularly read – but do not accept – mainstream and liberal news sources. They are isolated, not by selective exposure, but by changes in who they accept as authorities, experts and trusted sources.
  • we depend on a vastly complicated social structure of trust. We must trust each other, but, as the philosopher Annette Baier says, that trust makes us vulnerable. Echo chambers operate as a kind of social parasite on that vulnerability, taking advantage of our epistemic condition and social dependency.
  • I am quite confident that there are plenty of echo chambers on the political Left. More importantly, nothing about echo chambers restricts them to the arena of politics
  • The world of anti-vaccination is clearly an echo chamber, and it is one that crosses political lines. I’ve also encountered echo chambers on topics as broad as diet (Paleo!), exercise technique (CrossFit!), breastfeeding, some academic intellectual traditions, and many, many more
  • Here’s a basic check: does a community’s belief system actively undermine the trustworthiness of any outsiders who don’t subscribe to its central dogmas? Then it’s probably an echo chamber.
  • much of the recent analysis has lumped epistemic bubbles together with echo chambers into a single, unified phenomenon. But it is absolutely crucial to distinguish between the two.
  • Epistemic bubbles are rather ramshackle; they go up easily, and they collapse easily
  • Echo chambers are far more pernicious and far more robust. They can start to seem almost like living things. Their belief systems provide structural integrity, resilience and active responses to outside attacks
  • the two phenomena can also exist independently. And of the events we’re most worried about, it’s the echo-chamber effects that are really causing most of the trouble.
  • new data does, in fact, seem to show that people on Facebook actually do see posts from the other side, or that people often visit websites with opposite political affiliation.
  • their basis for evaluation – their background beliefs about whom to trust – are radically different. They are not irrational, but systematically misinformed about where to place their trust.
  • Many people have claimed that we have entered an era of ‘post-truth’.
  • Not only do some political figures seem to speak with a blatant disregard for the facts, but their supporters seem utterly unswayed by evidence. It seems, to some, that truth no longer matters.
  • This is an explanation in terms of total irrationality. To accept it, you must believe that a great number of people have lost all interest in evidence or investigation, and have fallen away from the ways of reason.
  • echo chambers offers a less damning and far more modest explanation. The apparent ‘post-truth’ attitude can be explained as the result of the manipulations of trust wrought by echo chambers.
  • We don’t have to attribute a complete disinterest in facts, evidence or reason to explain the post-truth attitude. We simply have to attribute to certain communities a vastly divergent set of trusted authorities.
  • An echo chamber doesn’t destroy their members’ interest in the truth; it merely manipulates whom they trust and changes whom they accept as trustworthy sources and institutions.
  • in many ways, echo-chamber members are following reasonable and rational procedures of enquiry. They’re engaging in critical reasoning. They’re questioning, they’re evaluating sources for themselves, they’re assessing different pathways to information. They are critically examining those who claim expertise and trustworthiness, using what they already know about the world
  • none of this weighs against the existence of echo chambers. We should not dismiss the threat of echo chambers based only on evidence about connectivity and exposure.
  • Notice how different what’s going on here is from, say, Orwellian doublespeak, a deliberately ambiguous, euphemism-filled language designed to hide the intent of the speaker.
  • echo chambers don’t trade in vague, ambiguous pseudo-speech. We should expect that echo chambers would deliver crisp, clear, unambiguous claims about who is trustworthy and who is not
  • clearly articulated conspiracy theories, and crisply worded accusations of an outside world rife with untrustworthiness and corruption.
  • Once an echo chamber starts to grip a person, its mechanisms will reinforce themselves.
  • In an epistemically healthy life, the variety of our informational sources will put an upper limit to how much we’re willing to trust any single person. Everybody’s fallible; a healthy informational network tends to discover people’s mistakes and point them out. This puts an upper ceiling on how much you can trust even your most beloved leader
  • nside an echo chamber, that upper ceiling disappears.
  • Being caught in an echo chamber is not always the result of laziness or bad faith. Imagine, for instance, that somebody has been raised and educated entirely inside an echo chamber
  • when the child finally comes into contact with the larger world – say, as a teenager – the echo chamber’s worldview is firmly in place. That teenager will distrust all sources outside her echo chamber, and she will have gotten there by following normal procedures for trust and learning.
  • It certainly seems like our teenager is behaving reasonably. She could be going about her intellectual life in perfectly good faith. She might be intellectually voracious, seeking out new sources, investigating them, and evaluating them using what she already knows.
  • The worry is that she’s intellectually trapped. Her earnest attempts at intellectual investigation are led astray by her upbringing and the social structure in which she is embedded.
  • Echo chambers might function like addiction, under certain accounts. It might be irrational to become addicted, but all it takes is a momentary lapse – once you’re addicted, your internal landscape is sufficiently rearranged such that it’s rational to continue with your addiction
  • Similarly, all it takes to enter an echo chamber is a momentary lapse of intellectual vigilance. Once you’re in, the echo chamber’s belief systems function as a trap, making future acts of intellectual vigilance only reinforce the echo chamber’s worldview.
  • There is at least one possible escape route, however. Notice that the logic of the echo chamber depends on the order in which we encounter the evidence. An echo chamber can bring our teenager to discredit outside beliefs precisely because she encountered the echo chamber’s claims first. Imagine a counterpart to our teenager who was raised outside of the echo chamber and exposed to a wide range of beliefs. Our free-range counterpart would, when she encounters that same echo chamber, likely see its many flaws
  • Those caught in an echo chamber are giving far too much weight to the evidence they encounter first, just because it’s first. Rationally, they should reconsider their beliefs without that arbitrary preference. But how does one enforce such informational a-historicity?
  • The escape route is a modified version of René Descartes’s infamous method.
  • Meditations on First Philosophy (1641). He had come to realise that many of the beliefs he had acquired in his early life were false. But early beliefs lead to all sorts of other beliefs, and any early falsehoods he’d accepted had surely infected the rest of his belief system.
  • The only solution, thought Descartes, was to throw all his beliefs away and start over again from scratch.
  • He could start over, trusting nothing and no one except those things that he could be entirely certain of, and stamping out those sneaky falsehoods once and for all. Let’s call this the Cartesian epistemic reboot.
  • Notice how close Descartes’s problem is to our hapless teenager’s, and how useful the solution might be. Our teenager, like Descartes, has problematic beliefs acquired in early childhood. These beliefs have infected outwards, infesting that teenager’s whole belief system. Our teenager, too, needs to throw everything away, and start over again.
  • Let’s call the modernised version of Descartes’s methodology the social-epistemic reboot.
  • when she starts from scratch, we won’t demand that she trust only what she’s absolutely certain of, nor will we demand that she go it alone
  • For the social reboot, she can proceed, after throwing everything away, in an utterly mundane way – trusting her senses, trusting others. But she must begin afresh socially – she must reconsider all possible sources of information with a presumptively equanimous eye. She must take the posture of a cognitive newborn, open and equally trusting to all outside sources
  • we’re not asking people to change their basic methods for learning about the world. They are permitted to trust, and trust freely. But after the social reboot, that trust will not be narrowly confined and deeply conditioned by the particular people they happened to be raised by.
  • Such a profound deep-cleanse of one’s whole belief system seems to be what’s actually required to escape. Look at the many stories of people leaving cults and echo chambers
  • Take, for example, the story of Derek Black in Florida – raised by a neo-Nazi father, and groomed from childhood to be a neo-Nazi leader. Black left the movement by, basically, performing a social reboot. He completely abandoned everything he’d believed in, and spent years building a new belief system from scratch. He immersed himself broadly and open-mindedly in everything he’d missed – pop culture, Arabic literature, the mainstream media, rap – all with an overall attitude of generosity and trust.
  • It was the project of years and a major act of self-reconstruction, but those extraordinary lengths might just be what’s actually required to undo the effects of an echo-chambered upbringing.
  • we need to attack the root, the systems of discredit themselves, and restore trust in some outside voices.
  • Stories of actual escapes from echo chambers often turn on particular encounters – moments when the echo-chambered individual starts to trust somebody on the outside.
  • Black’s is case in point. By high school, he was already something of a star on neo-Nazi media, with his own radio talk-show. He went on to college, openly neo-Nazi, and was shunned by almost every other student in his community college. But then Matthew Stevenson, a Jewish fellow undergraduate, started inviting Black to Stevenson’s Shabbat dinners. In Black’s telling, Stevenson was unfailingly kind, open and generous, and slowly earned Black’s trust. This was the seed, says Black, that led to a massive intellectual upheaval – a slow-dawning realisation of the depths to which he had been misled
  • Similarly, accounts of people leaving echo-chambered homophobia rarely involve them encountering some institutionally reported fact. Rather, they tend to revolve around personal encounters – a child, a family member, a close friend coming out.
  • hese encounters matter because a personal connection comes with a substantial store of trust.
  • We don’t simply trust people as educated experts in a field – we rely on their goodwill. And this is why trust, rather than mere reliability, is the key concept
  • goodwill is a general feature of a person’s character. If I demonstrate goodwill in action, then you have some reason to think that I also have goodwill in matters of thought and knowledge.
  • f one can demonstrate goodwill to an echo-chambered member – as Stevenson did with Black – then perhaps one can start to pierce that echo chamber.
  • the path I’m describing is a winding, narrow and fragile one. There is no guarantee that such trust can be established, and no clear path to its being established systematically.
  • what we’ve found here isn’t an escape route at all. It depends on the intervention of another. This path is not even one an echo-chamber member can trigger on her own; it is only a whisper-thin hope for rescue from the outside.

    I found this article very interesting as it discussed the logic fallacy and confirmation bias in humane mind.The danger of only seeing what they already believe is especially obvious in the era of Internet. More and more social medias use filter system to give viewers what they like to see based on their viewing history. Although this filter system can satisfy the viewers, viewers get a limited range of information. I think it limits the mindset of the viewers. --Sissi (3/23/2017)

  • There is a new group of gatekeepers in town, and this time, they’re not people, they’re code.
  • when personalization affects not just what you buy but how you think, different issues arise. Democracy depends on the citizen’s ability to engage with multiple viewpoints; the Internet limits such engagement when it offers up only information that reflects your already established point of view. While it’s sometimes convenient to see only what you want to see, it’s critical at other times that you see things that you don’t.

  • Today’s Internet giants — Google, Facebook, Yahoo and Microsoft — see the remarkable rise of available information as an opportunity. If they can provide services that sift though the data and supply us with the most personally relevant and appealing results, they’ll get the most users and the most ad views. As a result, they’re racing to offer personalized filters that show us the Internet that they think we want to see. These filters, in effect, control and limit the information that reaches our screens.
  • At Facebook, “relevance” is virtually the sole criterion that determines what users see. Focusing on the most personally relevant news — the squirrel — is a great business strategy. But it leaves us staring at our front yard instead of reading about suffering, genocide and revolution.
  • It is in our collective interest to ensure that the Internet lives up to its potential as a revolutionary connective medium. This won’t happen if we’re all sealed off in our own personalized online worlds.

  • When you whack yourself with a hammer, it feels like the pain is in your thumb. But really it's in your brain.
  • perception of pain is shaped by brain circuits that are constantly filtering the information coming from our sensory nerves,
  • In 2003, Turner was unloading supplies when his unit came under attack. He was wounded by a grenade. "He took shrapnel in his leg, in his side — and he didn't even notice that he had been hit,"

  • Those things will make the emotional component of the pain experience stronger."

  • A week ago, more than a year after the World Health Organization declared that we face a pandemic, a page on its website titled “Coronavirus Disease (Covid-19): How Is It Transmitted?” got a seemingly small update.
  • The revised response still emphasizes transmission in close contact but now says it may be via aerosols — smaller respiratory particles that can float — as well as droplets. It also adds a reason the virus can also be transmitted “in poorly ventilated and/or crowded indoor settings,” saying this is because “aerosols remain suspended in the air or travel farther than 1 meter.”
  • on Friday, the Centers for Disease Control and Prevention also updated its guidance on Covid-19, clearly saying that inhalation of these smaller particles is a key way the virus is transmitted, even at close range, and put it on top of its list of how the disease spreads.
  • ...38 more annotations...
  • But these latest shifts challenge key infection control assumptions that go back a century, putting a lot of what went wrong last year in context
  • They may also signal one of the most important advancements in public health during this pandemic.
  • If the importance of aerosol transmission had been accepted early, we would have been told from the beginning that it was much safer outdoors, where these small particles disperse more easily, as long as you avoid close, prolonged contact with others.
  • We would have tried to make sure indoor spaces were well ventilated, with air filtered as necessary.
  • Instead of blanket rules on gatherings, we would have targeted conditions that can produce superspreading events: people in poorly ventilated indoor spaces, especially if engaged over time in activities that increase aerosol production, like shouting and singing
  • We would have started using masks more quickly, and we would have paid more attention to their fit, too. And we would have been less obsessed with cleaning surfaces.
  • The implications of this were illustrated when I visited New York City in late April — my first trip there in more than a year.
  • A giant digital billboard greeted me at Times Square, with the message “Protecting yourself and others from Covid-19. Guidance from the World Health Organization.”
  • That billboard neglected the clearest epidemiological pattern of this pandemic: The vast majority of transmission has been indoors, sometimes beyond a range of three or even six feet. The superspreading events that play a major role in driving the pandemic occur overwhelmingly, if not exclusively, indoors.
  • The billboard had not a word about ventilation, nothing about opening windows or moving activities outdoors, where transmission has been rare and usually only during prolonged and close contact. (Ireland recently reported 0.1 percent of Covid-19 cases were traced to outdoor transmission.)
  • Mary-Louise McLaws, an epidemiologist at the University of New South Wales in Sydney, Australia, and a member of the W.H.O. committees that craft infection prevention and control guidance, wanted all this examined but knew the stakes made it harder to overcome the resistance. She told The Times last year, “If we started revisiting airflow, we would have to be prepared to change a lot of what we do.” She said it was a very good idea, but she added, “It will cause an enormous shudder through the infection control society.”
  • In contrast, if the aerosols had been considered a major form of transmission, in addition to distancing and masks, advice would have centered on ventilation and airflow, as well as time spent indoors. Small particles can accumulate in enclosed spaces, since they can remain suspended in the air and travel along air currents. This means that indoors, three or even six feet, while helpful, is not completely protective, especially over time.
  • To see this misunderstanding in action, look at what’s still happening throughout the world. In India, where hospitals have run out of supplemental oxygen and people are dying in the streets, money is being spent on fleets of drones to spray anti-coronavirus disinfectant in outdoor spaces. Parks, beaches and outdoor areas keep getting closed around the world. This year and last, organizers canceled outdoor events for the National Cherry Blossom Festival in Washington, D.C. Cambodian customs officials advised spraying disinfectant outside vehicles imported from India. The examples are many.
  • Meanwhile, many countries allowed their indoor workplaces to open but with inadequate aerosol protections. There was no attention to ventilation, installing air filters as necessary or even opening windows when possible, more to having people just distancing three or six feet, sometimes not requiring masks beyond that distance, or spending money on hard plastic barriers, which may be useless at best
  • clear evidence doesn’t easily overturn tradition or overcome entrenched feelings and egos. John Snow, often credited as the first scientific epidemiologist, showed that a contaminated well was responsible for a 1854 London cholera epidemic by removing the suspected pump’s handle and documenting how the cases plummeted afterward. Many other scientists and officials wouldn’t believe him for 12 years, when the link to a water source showed up again and became harder to deny.
  • Along the way to modern public health shaped largely by the fight over germs, a theory of transmission promoted by the influential public health figure Charles Chapin took hold
  • Dr. Chapin asserted in the early 1900s that respiratory diseases were most likely spread at close range by people touching bodily fluids or ejecting respiratory droplets, and did not allow for the possibility that such close-range infection could occur by inhaling small floating particles others emitted
  • He was also concerned that belief in airborne transmission, which he associated with miasma theories, would make people feel helpless and drop their guard against contact transmission. This was a mistake that would haunt infection control for the next century and more.
  • It was in this context in early 2020 that the W.H.O. and the C.D.C. asserted that SARS-CoV-2 was transmitted primarily via these heavier, short-range droplets, and provided guidance accordingly
  • Amid the growing evidence, in July, hundreds of scientists signed an open letter urging the public health agencies, especially the W.H.O., to address airborne transmission of the coronavirus.
  • Last October, the C.D.C. published updated guidance acknowledging airborne transmission, but as a secondary route under some circumstances, until it acknowledged airborne transmission as crucial on Friday. And the W.H.O. kept inching forward in its public statements, most recently a week ago.
  • Linsey Marr, a professor of engineering at Virginia Tech who made important contributions to our understanding of airborne virus transmission before the pandemic, pointed to two key scientific errors — rooted in a lot of history — that explain the resistance, and also opened a fascinating sociological window into how science can get it wrong and why.
  • Dr. Marr said that if you inhale a particle from the air, it’s an aerosol.
  • biomechanically, she said, nasal transmission faces obstacles, since nostrils point downward and the physics of particles that large makes it difficult for them to move up the nose. And in lab measurements, people emit far more of the easier-to-inhale aerosols than the droplets, she said, and even the smallest particles can be virus laden, sometimes more so than the larger ones, seemingly because of how and where they are produced in the respiratory tract.
  • Second, she said, proximity is conducive to transmission of aerosols as well because aerosols are more concentrated near the person emitting them. In a twist of history, modern scientists have been acting like those who equated stinky air with disease, by equating close contact, a measure of distance, only with the larger droplets, a mechanism of transmission, without examination.
  • Since aerosols also infect at close range, measures to prevent droplet transmission — masks and distancing — can help dampen transmission for airborne diseases as well. However, this oversight led medical people to circularly assume that if such measures worked at all, droplets must have played a big role in their transmission.
  • Another dynamic we’ve seen is something that is not unheard-of in the history of science: setting a higher standard of proof for theories that challenge conventional wisdom than for those that support it.
  • Another key problem is that, understandably, we find it harder to walk things back. It is easier to keep adding exceptions and justifications to a belief than to admit that a challenger has a better explanation.
  • The ancients believed that all celestial objects revolved around the earth in circular orbits. When it became clear that the observed behavior of the celestial objects did not fit this assumption, those astronomers produced ever-more-complex charts by adding epicycles — intersecting arcs and circles — to fit the heavens to their beliefs.
  • In a contemporary example of this attitude, the initial public health report on the Mount Vernon choir case said that it may have been caused by people “sitting close to one another, sharing snacks and stacking chairs at the end of the practice,” even though almost 90 percent of the people there developed symptoms of Covid-19
  • So much of what we have done throughout the pandemic — the excessive hygiene theater and the failure to integrate ventilation and filters into our basic advice — has greatly hampered our response.
  • Some of it, like the way we underused or even shut down outdoor space, isn’t that different from the 19th-century Londoners who flushed the source of their foul air into the Thames and made the cholera epidemic worse.
  • Righting this ship cannot be a quiet process — updating a web page here, saying the right thing there. The proclamations that we now know are wrong were so persistent and so loud for so long.
  • the progress we’ve made might lead to an overhaul in our understanding of many other transmissible respiratory diseases that take a terrible toll around the world each year and could easily cause other pandemics.
  • So big proclamations require probably even bigger proclamations to correct, or the information void, unnecessary fears and misinformation will persist, damaging the W.H.O. now and in the future.
  • I’ve seen our paper used in India to try to reason through aerosol transmission and the necessary mitigations. I’ve heard of people in India closing their windows after hearing that the virus is airborne, likely because they were not being told how to respond
  • The W.H.O. needs to address these fears and concerns, treating it as a matter of profound change, so other public health agencies and governments, as well as ordinary people, can better adjust.
  • It needs to begin a campaign proportional to the importance of all this, announcing, “We’ve learned more, and here’s what’s changed, and here’s how we can make sure everyone understands how important this is.” That’s what credible leadership looks like. Otherwise, if a web page is updated in the forest without the requisite fanfare, how will it matter?

The Worst Part of the Woodward Tapes Isn't COVID. - 0 views

  • 1. Woodward
  • I'd like to take the other side of this Trump-Woodward story and offer two curveball views:
  • (1) I do not believe that Donald Trump "knew" how dangerous the coronavirus was. Allow me to explain.
  • ...21 more annotations...
  • This is simply how the man talks. About everything. What's more, he says everything, takes the both sides of everything:
  • Does he believe any of this, either way? Almost certainly not. The man has the brain of a goldfish: He "believes" whatever is in front of him in the moment. No matter whether or not it contradicts something he believed five minutes ago or will believe ten minutes from now.
  • All this guy does is try to create panic. That's his move
  • (2) The most alarming part of the Woodward tapes is the way Trump talks about Kim Jong Un and the moment when Trump literally takes sides with Kim Jong Un against a former American president.
  • In a way, it would be comforting to believe that our president was intelligent enough to grasp the seriousness of the coronavirus, even if his judgment in how to deal with the outbreak was malicious or poor.
  • All of the available evidence suggests the opposite:
  • Donald Trump lacks the cognitive ability to understand any concepts more complicated than self-promotion or self-preservation.
  • Put those two together—constant exaggerating self-aggrandizement and the perpetual attempt to stoke panic—and what you have is a guy was just saying stuff to Woodward.
  • After the Woodward tapes, anyone still deluding themselves about the authoritarian danger Trump poses to America is, finally, all out of excuses.
  • This, right here, is the most damning revelation from the Woodward tapes (so far):   Trump reflected on his relationships with authoritarian leaders generally, including Turkish President Recep Tayyip Erdogan. “It’s funny, the relationships I have, the tougher and meaner they are, the better I get along with them,” he told Woodward. “You know? Explain that to me someday, okay?” It's not hard to explain. And it's not funny.
  • You have this incredible rise in interest in technology and excitement about technology and the beat itself really took off while I was there. But then at the same time, you have this massive new centralization of government control over technology and the use of technology to control people and along with that rising nationalism.
  • Paul Mozur, who covers China and tech for the New York Times and is currently living in Taiwain, after the Chinese expelled all foreign journalists. 
  • That was more apparent, I think, over the past five years or so after Xi Jinping really consolidated power, but the amount of cameras that went up on street corners, the degree to which you used to be able to — there’s a moment maybe seven or eight years ago — where Jack Ma talked about the Tiananmen Square crackdowns on Chinese social media and now that’s just so utterly unthinkable. The degree to which the censorship has increased now to the level where if you say certain things on WeChat, it’s very possible the police will show up at your door where you actually have a truly fully formed Internet Police. . .
  • I think a lot of Chinese people feel more secure from the cameras, there’s been a lot of propaganda out there saying the cameras are here for your safety. There is this extremely positive, almost Utopian take on technology in China, and a lot of the stuff that I think, our knee-jerk response from the United States would be to be worried about, they kind of embrace as a vision of the future. .
  • The main reasons WeChat is a concern if you were the United States government is number one, it’s become a major vector of the spread of Chinese propaganda and censorship, and because it’s a social network that is anchored by a vast majority of users in China who are censored and who are receptive to all this propaganda, even if you’re overseas using WeChat and not censored in the same way, what you get is mostly content shared from people who are living in a censored environment, so it basically stays a censored environment. I call that a super filter bubble; the idea is that there are multiple filter bubbles contending in a website like Facebook, but with WeChat, because it’s so dominated by government controls, you get one really big mega pro-China filter bubble that then is spread all over the the world over the app, even if people outside of China don’t face the same censorship. So that’s one thing.
  • The second is the surveillance is immense and anybody who creates an account in China brings the surveillance with them overseas
  • And most people, frankly, using WeChat overseas probably created the accounts in China, and even when they don’t create the account in China, when national security priorities hit a certain level, I think they’re probably going to use it to monitor people anyway. I’ve run into a number of people who have had run-ins with the Chinese Internet Police either in China, but some of them outside of China, in their day-to-day life using WeChat, and then they return home and it becomes apparent that the Internet Police were watching them the whole time, and they get a visit and the police have a discussion with them about what their activities have been
  • So it’s also a major way that the Chinese government is able to spy on and monitor people overseas and then unsurprisingly, because of that, it’s used as a way for the Chinese intel services to harass people overseas. . . .
  • WeChat is particularly suited to this in part because every single person who uses WeChat within China has it linked to their real identity. And then because everybody on WeChat has linked to their real identity, you can map their relationship networks and lean on them that way.
  • It also has a bunch of tools that the Chinese police use, for instance key words, where you can set an alarm so that if you were to say “Tiananmen”, they could set an alarm so that anytime you say that they get a warning about that, and then they go look at what you’ve written. So there’s all these tools that are uniquely created for Chinese state surveillance that are within the app that they can also use, so there’s a bunch of ways that the app is just better.
  • It’s also one of the very few unblocked communication tools that goes between the two countries. So for all these reasons it’s a very, very big deal. For the Chinese government, it’s an important tool of social control, and it’s been a way that they’ve been able to take the social controls that exist within China and expand them to the diaspora community in some pretty unnerving ways.

media algorithm facebook social media news power influence

shared by Javier E on 16 May 16 - No Cached
  • power essentially comes in three varieties: the ability to compel people to do what they don’t want to do; the capability to stop them doing what they want to do; and the power to shape the way they think
  • This last is the kind of power exercised by our mass media. They can shape the public (and therefore the political) agenda by choosing the news that people read, hear or watch; and they can shape the ways in which that news is presented.
  • For a long time, Google was the 800lb gorilla in this domain, because its dominance of search determined what people could find in the unimaginable wastelands of cyberspace
  • ...7 more annotations...
  • search could be – and was – personalised, because Google’s algorithms could figure out what each user was most likely to be interested in, and therefore what kinds of information would be most relevant for her or him. So, imperceptibly, but inexorably over time, we have come to live in what Eli Pariser christened a “filter bubble”.
  • Before the internet, our problem with information was its scarcity. Now our problem is unmanageable abundance. So now the scarce resources are attention and time, over which a vicious war has broken out between traditional media and the internet-based upstarts.
  • YouTube has a billion users, half of whom access it via mobile devices. The average time spent on the site is 40 minutes. Facebook now claims to have 1.65 billion monthly active users, who spend on average 50 minutes a day on its services. So if Google is an 800lb gorilla, Facebook is a megaton King Kong.
  • Competition for attention and time is a zero-sum game that traditional media are losing. In desperation, they are trying both to appease Facebook and to harness its hold on people’s attention
  • In doing so, they have entered into a truly Faustian bargain. Because while publishers can without difficulty ship their stuff to Instant Articles, they cannot control which ones Facebook users actually get to see. This is because users’ news feeds are determined by Facebook’s machine-learning algorithms that try to guess what each user would like to see (and what might dispose them to click on an advertisement).
  • when you ask – as Professor George Brock memorably did – whether Mark Zuckerberg and his satraps understand that they have acquired editorial responsibilities, they look blank. Facebook is not a publisher, they explain, merely a “platform”. And, besides, no humans are involved in curating users’ news feeds: it’s all done by algorithms and is therefore neutral. In other words: nothing to see here; move on.
  • Any algorithm that has to make choices has criteria that are specified by its designers. And those criteria are expressions of human values. Engineers may think they are “neutral”, but long experience has shown us they are babes in the woods of politics, economics and ideology.

  • The social network is going to partner with the Poynter International Fact-Checking Network, which includes groups such as Snopes and the Associated Press, to evaluate articles flagged by Facebook users. If those articles do not pass the smell test for the fact-checkers, Facebook will label that evaluation whenever they are posted or shared, along with a link to the organization that debunked the story.
  • Mosseri said the social network still wants to be a place where people with all kinds of opinions can express themselves but has no interest in being the arbiter of what’s true and what's not for its 1 billion users.
  • The new system will work like this: If a story on Facebook is patently false — saying that a celebrity is dead when they are still alive, for example — then users will see a notice that the story has been disputed or debunked. People who try to share stories that have been found false will also see an alert before they post. Flagged stories will appear lower in the news feed than unflagged stories.
  • ...9 more annotations...
  • Users will also be able to report potentially false stories to Facebook or send messages directly to the person posting a questionable article.
  • The company is focusing, for now, on what Mosseri called the “bottom of the barrel” websites that are purposefully set up to deceive and spread fake news, as well as those that are impersonating other news organizations. “We are not looking to flag legitimate organizations,” Mosseri said. “We’re looking for pages posing as legitimate organizations.” Articles from legitimate sites that are controversial or even wrong should not get flagged, he said.
  • The company will also prioritize checking stories that are getting lots of flags from users and are being shared widely, to go after the biggest targets possible.
  • "From a journalistic side, is it enough? It’s a little late.”
  • Facebook is fine to filter out other content -- such as pornography -- for which the definition is unclear. There's no clear explanation for why Facebook hasn't decided to apply similar filters to fake news. “I think that’s a little weak,” Tu said. “If you recognize that it’s bad and journalists at the AP say it’s bad, you shouldn’t have it on your site.”
  • Others said Facebook's careful approach may be warranted. "I think we'll have to wait and see early results to determine how effective the strategy is," said Alexios Mantzarlis, of Poynter's International Fact-Checking Network. "In my eyes, erring on the side of caution is not a bad idea with something so complicated," he said
  • Facebook is also trying to crack down on people who have made a business in fake news by tweaking the social network's advertising practices. Any article that has been disputed, for example, cannot be used in an ad. Facebook is also playing around with ways to limit links from publishers with landing pages that are mostly ads — a common tactic for fake-news websites
  • With those measures in place, “we’re hoping financially motivated spammers might move away from fake news,” Mosseri said
  • Paul Horner, a fake news writer who makes a living writing viral hoaxes, said he wasn't immediately worried about Facebook's new crackdown on fake news sites. "It's really easy to start a new site. I have 50 domain names. I have a dedicated server. I can start up a new site within 48 hours," he said, shortly after Facebook announced its new anti-hoax programs.  If his sites, which he describes as "satire"-focused, do end up getting hit too hard, Horner says he has "backup plans."

NSF Report Flawed; Americans Do Not Believe Astrology is Scientific | NeoAcademic - 0 views

astrology science psychology survey method

shared by Javier E on 22 Feb 14 - No Cached
  • The problem with human subjects data – as any psychologist like myself will tell you – is that simply asking someone a question rarely gives you the information that you think it does. When you ask someone to respond to a question, it must pass through a variety of mental filters, and these filters often cause people’s answers to differ from reality. Some of these processes are conscious and others are not
  • Learning, and by extension knowledge, are no different. People don’t always know what they know. And this NSF report is a fantastic example of this in action. The goal of the NSF researchers was to assess, “Do US citizens believe astrology is scientific?” People were troubled that young people now apparently believe astrology is more scientific than in the past. But this interpretation unwisely assumes that people accurately interpret the word astrology. It assumes that they know what astrology is and recognize that they know it in order to respond authentically
  • When I saw the NSF report, I was reminded of my own poor understanding of these terms. “Surely,” I said to myself, “it’s not that Americans believe astrology is scientific. Instead, they must be confusing astronomy with astrology, like I did those many years ago.” Fortunately, I had a very quick way to answer this question: Amazon Mechanical Turk (MTurk).
  • ...2 more annotations...
  • MTurk is a fantastic tool available to quickly collect human subjects data. It pulls from a massive group of people looking to complete small tasks for small amounts of money. So for 5 cents per survey, I collected 100 responses to a short survey from American MTurk Workers. It asked only 3 questions:Please define astrology in 25 words or less.Do you believe astrology to be scientific? (using the same scale as the NSF study)What is your highest level of education completed? (using the same scale as the NSF study)
  • Among those that correctly identified astrology as astrology, only 13.5% found it “pretty scientific” or “very scientific”. Only 1 person said it was “very scientific.” Among those that identified astrology as astronomy, the field was overwhelmingly seen as scientific, exactly as I expected. This is the true driver of the NSF report findings

reading technology brain science books intellectual

shared by Javier E on 22 Jan 11 - No Cached
  • Neurologically, how does our brain adapt itself to new technologies? Nicholas Carr: A couple of types of adaptations take place in your brain. One is a strengthening of the synaptical connections between the neurons involved in using that instrument, in using that tool. And basically these are chemical – neural chemical changes. So you know, cells in our brain communicate by transmitting electrical signals between them and those electrical signals are actually activated by the exchange of chemicals, neurotransmitters in our synapses. And so when you begin to use a tool, for instance, you have much stronger electrochemical signals being processed in those – through those synaptical connections. And then the second, and even more interesting adaptation is in actual physical changes,anatomical changes. Your neurons, you may grow new neurons that are then recruited into these circuits or your existing neurons may grow new synaptical terminals. And again, that also serves to strengthen the activity in those, in those particular pathways that are being used – new pathways. On the other hand, you know, the brain likes to be efficient and so even as its strengthening the pathways you’re exercising, it’s pulling – it’s weakening the connections in other ways between the cells that supported old ways of thinking or working or behaving, or whatever that you’re not exercising so much.
  • And it was only in around the year 800 or 900 that we saw the introduction of word spaces. And suddenly reading became, in a sense, easier and suddenly you had to arrival of silent reading, which changed the act of reading from just transcription of speech to something that every individual did on their own. And suddenly you had this whole deal of the silent solitary reader who was improving their mind, expanding their horizons, and so forth. And when Guttenberg invented the printing press around 1450, what that served to do was take this new very attentive, very deep form of reading, which had been limited to just, you know, monasteries and universities, and by making books much cheaper and much more available, spread that way of reading out to a much larger mass of audience. And so we saw, for the last 500 years or so, one of the central facts of culture was deep solitary reading.
  • What the book does as a technology is shield us from distraction. The only thinggoing on is the, you know, the progression of words and sentences across page after page and so suddenly we see this immersive kind of very attentive thinking, whether you are paying attention to a story or to an argument, or whatever. And what we know about the brain is the brain adapts to these types of tools.
  • ...12 more annotations...
  • we adapt to the environment of the internet, which is an environment of kind of constant immersion and information and constant distractions, interruptions, juggling lots of messages, lots of bits of information.
  • Because it’s no longer just a matter of personal choice, of personal discipline, though obviously those things are always important, but what we’re seeing and we see this over and over again in the history of technology, is that the technology – the technology of the web, the technology of digital media, gets entwined very, very deeply into social processes, into expectations. So more and more, for instance in our work lives. You know, if our boss and all our colleagues are constantly exchanging messages, constantly checking email on their Blackberry or iPhone or their Droid or whatever, then it becomes very difficult to say, I’m not going to be as connected because you feel like you’re career is going to take a hit.
  • With the arrival – with the transfer now of text more and more onto screens, we see, I think, a new and in some ways more primitive way of reading. In order to take in information off a screen, when you are also being bombarded with all sort of other information and when there links in the text where you have to think even for just a fraction of a second, you know, do I click on this link or not. Suddenly reading again becomes a more cognitively intensive act, the way it was back when there were no spaces between words.
  • If all your friends are planning their social lives through texts and Facebook and Twitter and so forth, then to back away from that means to feel socially isolated. And of course for all people, particularly for young people, there’s kind of nothing worse than feeling socially isolated, that your friends are you know, having these conversations and you’re not involved. So it’s easy to say the solution, which is to, you know, becomes a little bit more disconnected. What’s hard it actually doing that.
  • if you want to change your brain, you change your habits. You change your habits of thinking. And that means, you know, setting aside time to engage in more contemplative, more reflective ways of thinking and that means, you know, setting aside time to engage in more contemplative, more reflective ways of thinking, to be – to screen out distractions. And that means retreating from digital media and from the web and from Smart Phones and texting and Facebook and Tweeting and everything else.
  • The Thinker was, you know, in a contemplative pose and was concentrating deeply, and wasn’t you know, multi-tasking. And because that is something that, until recently anyway, people always thought was the deepest and most distinctly human way of thinking.
  • we may end up finding that those are actually the most valuable ways of thinking that are available to us as human beings.
  • the ability to pay attention also is very important for our ability to build memories, to transfer information from our short-term memory to our long-term memory. And only when we do that do we weave new information into everything else we have stored in our brains. All the other facts we’ve learned, all the other experiences we’ve had, emotions we’ve felt. And that’s how you build, I think, a rich intellect and a rich intellectual life.
  • On the other hand, there is a cost. We lose – we begin to lose the facilities that we don’t exercise. So adaptation has both a very, very positive side, but also a potentially negative side because ultimately our brain is qualitatively neutral. It doesn’t pare what it’s strengthening or what it’s weakening, it just responds to the way we’re exercising our mind.
  • the book in some ways is the most interesting from our own present standpoint, particularly when we want to think about the way the internet is changing us. It’s interesting to think about how the book changed us.
  • So we become, after the arrival of the printing press in general, more attentive more attuned to contemplative ways of thinking. And that’s a very unnatural way of using our mind. You know, paying attention, filtering out distractions.
  • what we lose is the ability to pay deep attention to one thing for a sustained period of time, to filter out distractions.

  • ...61 more annotations...
  • Empowered by their own sources of information and their own interpretations of research, doubters have declared war on the consensus of experts.
  • Our lives are permeated by science and technology as never before. For many of us this new world is wondrous, comfortable, and rich in rewards—but also more complicated and sometimes unnerving. We now face risks we can’t easily analyze.
  • The world crackles with real and imaginary hazards, and distinguishing the former from the latter isn’t easy.
  • In this bewildering world we have to decide what to believe and how to act on that. In principle that’s what science is for.
  • “Science is not a body of facts,” says geophysicist Marcia McNutt,
  • “Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not.”
  • The scientific method leads us to truths that are less than self-evident, often mind-blowing, and sometimes hard to swallow.
  • We don’t believe you.
  • Galileo was put on trial and forced to recant. Two centuries later Charles Darwin escaped that fate. But his idea that all life on Earth evolved from a primordial ancestor and that we humans are distant cousins of apes, whales, and even deep-sea mollusks is still a big ask for a lot of people. So is another 19th-century notion: that carbon dioxide, an invisible gas that we all exhale all the time and that makes up less than a tenth of one percent of the atmosphere, could be affecting Earth’s climate.
  • we intellectually accept these precepts of science, we subconsciously cling to our intuitions
  • Shtulman’s research indicates that as we become scientifically literate, we repress our naive beliefs but never eliminate them entirely. They lurk in our brains, chirping at us as we try to make sense of the world.
  • Most of us do that by relying on personal experience and anecdotes, on stories rather than statistics.
  • We have trouble digesting randomness; our brains crave pattern and meaning.
  • we can deceive ourselves.
  • Even for scientists, the scientific method is a hard discipline. Like the rest of us, they’re vulnerable to what they call confirmation bias—the tendency to look for and see only evidence that confirms what they already believe. But unlike the rest of us, they submit their ideas to formal peer review before publishing them
  • other scientists will try to reproduce them
  • Scientific results are always provisional, susceptible to being overturned by some future experiment or observation. Scientists rarely proclaim an absolute truth or absolute certainty. Uncertainty is inevitable at the frontiers of knowledge.
  • Many people in the United States—a far greater percentage than in other countries—retain doubts about that consensus or believe that climate activists are using the threat of global warming to attack the free market and industrial society generally.
  • news media give abundant attention to such mavericks, naysayers, professional controversialists, and table thumpers. The media would also have you believe that science is full of shocking discoveries made by lone geniuses
  • science tells us the truth rather than what we’d like the truth to be. Scientists can be as dogmatic as anyone else—but their dogma is always wilting in the hot glare of new research.
  • But industry PR, however misleading, isn’t enough to explain why only 40 percent of Americans, according to the most recent poll from the Pew Research Center, accept that human activity is the dominant cause of global warming.
  • “science communication problem,”
  • yielded abundant new research into how people decide what to believe—and why they so often don’t accept the scientific consensus.
  • higher literacy was associated with stronger views—at both ends of the spectrum. Science literacy promoted polarization on climate, not consensus. According to Kahan, that’s because people tend to use scientific knowledge to reinforce beliefs that have already been shaped by their worldview.
  • “egalitarian” and “communitarian” mind-set are generally suspicious of industry and apt to think it’s up to something dangerous that calls for government regulation; they’re likely to see the risks of climate change.
  • “hierarchical” and “individualistic” mind-set respect leaders of industry and don’t like government interfering in their affairs; they’re apt to reject warnings about climate change, because they know what accepting them could lead to—some kind of tax or regulation to limit emissions.
  • For a hierarchical individualist, Kahan says, it’s not irrational to reject established climate science: Accepting it wouldn’t change the world, but it might get him thrown out of his tribe.
  • Science appeals to our rational brain, but our beliefs are motivated largely by emotion, and the biggest motivation is remaining tight with our peers.
  • organizations funded in part by the fossil fuel industry have deliberately tried to undermine the public’s understanding of the scientific consensus by promoting a few skeptics.
  • Internet makes it easier than ever for climate skeptics and doubters of all kinds to find their own information and experts
  • Internet has democratized information, which is a good thing. But along with cable TV, it has made it possible to live in a “filter bubble” that lets in only the information with which you already agree.
  • How to convert climate skeptics? Throwing more facts at them doesn’t help.
  • people need to hear from believers they can trust, who share their fundamental values.
  • We believe in scientific ideas not because we have truly evaluated all the evidence but because we feel an affinity for the scientific community.
  • “Believing in evolution is just a description about you. It’s not an account of how you reason.”
  • evolution actually happened. Biology is incomprehensible without it. There aren’t really two sides to all these issues. Climate change is happening. Vaccines really do save lives. Being right does matter—and the science tribe has a long track record of getting things right in the end. Modern society is built on things it got right.
  • Doubting science also has consequences.
  • In the climate debate the consequences of doubt are likely global and enduring. In the U.S., climate change skeptics have achieved their fundamental goal of halting legislative action to combat global warming.
  • “That line between science communication and advocacy is very hard to step back from,”
  • It’s their very detachment, what you might call the cold-bloodedness of science, that makes science the killer app.
  • that need to fit in is so strong that local values and local opinions are always trumping science.
  • not a sin to change your mind when the evidence demands it.
  • for the best scientists, the truth is more important than the tribe.
  • Students come away thinking of science as a collection of facts, not a method.
  • Shtulman’s research has shown that even many college students don’t really understand what evidence is.
  • “Everybody should be questioning,” says McNutt. “That’s a hallmark of a scientist. But then they should use the scientific method, or trust people using the scientific method, to decide which way they fall on those questions.”
  • science has made us the dominant organisms,
  • incredibly rapid change, and it’s scary sometimes. It’s not all progress.

  • The scientific method doesn’t come naturally—but if you think about it, neither does democracy. For most of human history neither existed. We went around killing each other to get on a throne, praying to a rain god, and for better and much worse, doing things pretty much as our ancestors did.
  • We need to get a lot better at finding answers, because it’s certain the questions won’t be getting any simpler.
  • That the Earth is round has been known since antiquity—Columbus knew he wouldn’t sail off the edge of the world—but alternative geographies persisted even after circumnavigations had become common
  • We live in an age when all manner of scientific knowledge—from climate change to vaccinations—faces furious opposition.Some even have doubts about the moon landing.
  • Why Do Many Reasonable People Doubt Science?
  • science doubt itself has become a pop-culture meme.
  • Flat-Earthers held that the planet was centered on the North Pole and bounded by a wall of ice, with the sun, moon, and planets a few hundred miles above the surface. Science often demands that we discount our direct sensory experiences—such as seeing the sun cross the sky as if circling the Earth—in favor of theories that challenge our beliefs about our place in the universe.
  • . Yet just because two things happened together doesn’t mean one caused the other, and just because events are clustered doesn’t mean they’re not still random.
  • Sometimes scientists fall short of the ideals of the scientific method. Especially in biomedical research, there’s a disturbing trend toward results that can’t be reproduced outside the lab that found them, a trend that has prompted a push for greater transparency about how experiments are conducted
  • “Science will find the truth,” Collins says. “It may get it wrong the first time and maybe the second time, but ultimately it will find the truth.” That provisional quality of science is another thing a lot of people have trouble with.

  • they will continue to trump science, especially when there is no clear downside to ignoring science.”

  • a newly emerging model of how the brain focuses attention on a particular task, using neurons in the thalamic reticular nucleus as a switchboard to control the amount of information the brain receives, limiting and filtering out sensory information that we don't want to pay attention to
  • People need to be able to focus on one thing and suppress other distractions to perform everyday functions such as driving, talking on the phone, and socializing
  • sets the stage for ever more detailed studies on the complex behavior involved in how the mammalian brain pays attention to what's important, and especially how those neural circuits are broken in cases of attention-deficit diseases, such as ADHD, autism, and schizophrenia
  • ndividual TRN neurons that act like a "switchboard," continuously filtering sensory information and shifting more or less attention onto one sense
  • The test, they say, was designed to gauge how well the area of the brain known to control higher behavioral functions, the prefrontal cortex, could direct the focus on one sense over another
  • researchers distracted the mice with opposing stimuli: If the mouse was expecting a flash of light to guide it to the milk reward, the researchers distracted it with a sound, and vice versa. Distracting the mice decreased their ability to collect the food reward to 70 percent from nearly 90 percent, even if the distracting stimulus was removed later
  • found that inactivating the prefrontal cortex region of the brain, which is believed responsible for decision-making in complex behaviors, disrupted TRN neural signaling and reduced mice to only random success in obtaining a milk reward when presented with specifically cued light or sound signals
  • Inactivating the TRN, while leaving the cortical regions intact, also diminished success with obtaining the prompted food reward
  • prefrontal cortex is essential to performing such behavioral tasks
  • this part of the brain "stores the knowledge ultimately communicated to the TRN to control how much visual or auditory sensory information is suppressed or not, and how the brain ultimately multitasks

    I think this is gender stereotyping. People tend to make the assumption that women are more limited than men because they appear so emotional and irrational. However, in brain science, there is no real difference between male and female. The logic fallacies and flaws in reasoning stay true for everybody, not a specific gender. We also tends to label things to simplify. However, there are always exceptions to labels, as we learned in science. Labeling may filter out some really good stuff just based on our imprecise impression. -Sissi (3/4/2017)

  • Soya’s fame illustrated a simple truth: that social media is less a reflection of who we are, and more a performance of who we want to be.
  • It also seemed to herald a darker future where our fundamental senses of reality are under siege: The AI that allows anyone to fabricate a face can also be used to harass women with “deepfake” pornography, invent fraudulent LinkedIn personas and digitally impersonate political enemies.
  • As the photos began receiving hundreds of likes, Soya’s personality and style began to come through. She was relentlessly upbeat. She never sneered or bickered or trolled. She explored small towns, savored scenic vistas, celebrated roadside restaurants’ simple meals.
  • ...25 more annotations...
  • She took pride in the basic things, like cleaning engine parts. And she only hinted at the truth: When one fan told her in October, “It’s great to be young,” Soya replied, “Youth does not mean a certain period of life, but how to hold your heart.”
  • She seemed, well, happy, and FaceApp had made her that way. Creating the lifelike impostor had taken only a few taps: He changed the “Gender” setting to “Female,” the “Age” setting to “Teen,” and the “Impression” setting — a mix of makeup filters — to a glamorous look the app calls “Hollywood.”
  • Soya pouted and scowled on rare occasions when Nakajima himself felt frustrated. But her baseline expression was an extra-wide smile, activated with a single tap.
  • Nakajima grew his shimmering hair below his shoulders and raided his local convenience store for beauty supplies he thought would make the FaceApp images more convincing: blushes, eyeliners, concealers, shampoos.
  • “When I compare how I feel when I started to tweet as a woman and now, I do feel that I’m gradually gravitating toward this persona … this fantasy world that I created,” Nakajima said. “When I see photos of what I tweeted, I feel like, ‘Oh. That’s me.’ ”
  • The sensation Nakajima was feeling is so common that there’s a term for it: the Proteus effect, named for the shape-shifting Greek god. Stanford University researchers first coined it in 2007 to describe how people inhabiting the body of a digital avatar began to act the part
  • People made to appear taller in virtual-reality simulations acted more assertively, even after the experience ended. Prettier characters began to flirt.
  • What is it about online disguises? Why are they so good at bending people’s sense of self-perception?
  • they tap into this “very human impulse to play with identity and pretend to be someone you’re not.”
  • Users in the Internet’s early days rarely had any presumptions of authenticity, said Melanie C. Green, a University of Buffalo professor who studies technology and social trust. Most people assumed everyone else was playing a character clearly distinguished from their real life.
  • “This identity play was considered one of the huge advantages of being online,” Green said. “You could switch your gender and try on all of these different personas. It was a playground for people to explore.”
  • It wasn’t until the rise of giant social networks like Facebook — which used real identities to, among other things, supercharge targeted advertising — that this big game of pretend gained an air of duplicity. Spaces for playful performance shrank, and the biggest Internet watering holes began demanding proof of authenticity as a way to block out malicious intent.
  • The Web’s big shift from text to visuals — the rise of photo-sharing apps, live streams and video calls — seemed at first to make that unspoken rule of real identities concrete. It seemed too difficult to fake one’s appearance when everyone’s face was on constant display.
  • Now, researchers argue, advances in image-editing artificial intelligence have done for the modern Internet what online pseudonyms did for the world’s first chat rooms. Facial filters have allowed anyone to mold themselves into the character they want to play.
  • researchers fear these augmented reality tools could end up distorting the beauty standards and expectations of actual reality.
  • Some political and tech theorists worry this new world of synthetic media threatens to detonate our concept of truth, eroding our shared experiences and infusing every online relationship with suspicion and self-doubt.
  • Deceptive political memes, conspiracy theories, anti-vaccine hoaxes and other scams have torn the fabric of our democracy, culture and public health.
  • But she also thinks about her kids, who assume “that everything online is fabricated,” and wonders whether the rules of online identity require a bit more nuance — and whether that generational shift is already underway.
  • “Bots pretending to be people, automated representations of humanity — that, they perceive as exploitative,” she said. “But if it’s just someone engaging in identity experimentation, they’re like: ‘Yeah, that’s what we’re all doing.'
  • To their generation, “authenticity is not about: ‘Does your profile picture match your real face?’ Authenticity is: ‘Is your voice your voice?’
  • “Their feeling is: ‘The ideas are mine. The voice is mine. The content is mine. I’m just looking for you to receive it without all the assumptions and baggage that comes with it.’ That’s the essence of a person’s identity. That’s who they really are.”
  • But wasn’t this all just a big con? Nakajima had tricked people with a “cool girl” stereotype to boost his Twitter numbers. He hadn’t elevated the role of women in motorcycling; if anything, he’d supplanted them. And the character he’d created was paper thin: Soya had no internal complexity outside of what Nakajima had projected, just that eternally superimposed smile.
  • Perhaps he should have accepted his irrelevance and faded into the digital sunset, sharing his life for few to see. But some of Soya’s followers have said they never felt deceived: It was Nakajima — his enthusiasm, his attitude about life — they’d been charmed by all along. “His personality,” as one Twitter follower said, “shined through.”
  • In Nakajima’s mind, he’d used the tools of a superficial medium to craft genuine connections. He had not felt real until he had become noticed for being fake.
  • Nakajima said he doesn’t know how long he’ll keep Soya alive. But he said he’s grateful for the way she helped him feel: carefree, adventurous, seen.

  • The platforms are designed to be addictive and are associated with anxiety, depression, and even physical ailments.
  • According to the Pew Research Center, 69% of adults and 81% of teens in the U.S. use social media.
  • To boost self-esteem and feel a sense of belonging in their social circles, people post content with the hope of receiving positive feedback. Couple that content with the structure of potential future reward, and you get a recipe for constantly checking platforms.
  • ...8 more annotations...
  • FOMO—fear of missing out—also plays a role
  • A 2018 British study tied social media use to decreased, disrupted, and delayed sleep, which is associated with depression, memory loss, and poor academic performance.
  • Social media use can affect users’ physical health even more directly. Researchers know the connection between the mind and the gut can turn anxiety and depression into nausea, headaches, muscle tension, and tremors.
  • The earlier teens start using social media, the greater impact the platforms have on mental health. This is especially true for females. While teen males tend to express aggression physically, females do so relationally by excluding others and sharing hurtful comments. Social media increases the opportunity for such harmful interactions.
  • In the past, teens read magazines that contained altered photos of models. Now, these images are one thumb-scroll away at any given time. Apps that provide the user with airbrushing, teeth whitening, and more filters are easy to find and easier to use. It’s not only celebrities who look perfect—it’s everyone.
  • In recent years, plastic surgeons have seen an uptick in requests from patients who want to look like their filtered Snapchat and Instagram photos.
  • A person experiences impostor syndrome when feeling chronic self-doubt and a sense of being exposed as ‘a fraud’ in terms of success and intellect. “Whether it’s another pretty vacation or someone’s bouquet of flowers, my mind went from ‘Why not me?’ to ‘I don’t deserve those things, and I don’t know why,’ and it made me feel awful.”
  • Sperling encourages people to conduct their own behavior experiments by rating their emotions on a scale of 0-10, with 10 being the most intensely one could experience an emotion, before and after using social media sites at the same time each day for a week.

How the Language We Speak Affects the Way We Think | Psychology Today - 0 views

  • The story begins with the first American linguists who described (scientifically) some of the languages spoken by Native Americans. They discovered many awkward differences compared to the languages they had learned in school (ancient Greek, Latin, English, German, and the like).
  • They found sounds never heard in European languages (like ejective consonants), strange meanings encoded in the grammar (like parts of the verb referring to shapes of the objects), or new grammatical categories (like evidentiality, that is, the source of knowledge about the facts in a sentence).
  • Not surprisingly, some of these linguists concluded that such strange linguistic systems should have an effect on the mind of their speakers
  • ...10 more annotations...
  • Edward Sapir, one of the most influential American linguists, wrote: “The worlds in which different societies live are distinct worlds, not merely the same worlds with different labels attached” (Sapir, 1949: 162).
  • Now it was suggested that the world might be perceived differently by people speaking different languages.
  • This effect of framing or filtering is the main effect we can expect—regarding language—from perception and thought. Languages do not limit our ability to perceive the world or to think about the world, but they focus our perception, attention, and thought on specific aspects of the world.
  • Chinese-speaking children learn to count earlier than English-speaking children because Chinese numbers are more regular and transparent than English numbers (in Chinese, "eleven" is "ten one").
  • So, different languages focus the attention of their speakers on different aspects of the environment—either physical or cultural.
  • We linguists say that these salient aspects are either lexicalized or grammaticalised. Lexicalizing means that you have words for concepts, which work as shorthands for those concepts. This is useful because you don't need to explain (or paraphrase) the meaning you want to convey.
  • The lexicon is like a big, open bag: Some words are coined or borrowed because you need them for referring to new objects, and they are put into the bag. Conversely, some objects are not used anymore, and then the words for them are removed from the bag.
  • Dyirbal, a language spoken in Northern Australia, for example, has four noun classes (like English genders).
  • This grammatical classification of nouns involves a coherent view of the world, including an original mythology.
  • In summary, language functions as a filter of perception, memory, and attention. Whenever we construct or interpret a linguistic statement, we need to focus on specific aspects of the situation that the statement describes

creativity innovation ideas technique learning method principles

shared by Javier E on 03 Mar 13 - No Cached
  • In learning any art the important things to learn are, first, Principles, and second, Method. This is true of the art of producing ideas. Particular bits of knowledge are nothing, because they are made up [of] so called rapidly aging facts. Principles and method are everything.
  • So with the art of producing ideas. What is most valuable to know is not where to look for a particular idea, but how to train the mind in the method by which all ideas are produced and how to grasp the principles which are at the source of all ideas.
  • Every really good creative person…whom I have ever known has always had two noticeable characteristics. First, there was no subject under the sun in which he could not easily get interested — from, say, Egyptian burial customs to modern art. Every facet of life had fascination for him. Second, he was an extensive browser in all sorts of fields of information.
  • ...7 more annotations...
  • What you do is to take the different bits of material which you have gathered and feel them all over, as it were, with the tentacles of the mind. You take one fact, turn it this way and that, look at it in different lights, and feel for the meaning of it. You bring two facts together and see how they fit. What you are seeking now is the relationship, a synthesis where everything will come together in a neat combination, like a jig-saw puzzle.
  • Then and only then, Young promises, everything will click in the fourth stage of the seemingly serendipitous a-ha! moment: Out of nowhere the Idea will appear. It will come to you when you are least expecting it
  • In his third stage of the creative process, Young stresses the importance of making absolutely “no effort of a direct nature”: It is important to realize that this is just as definite and just as necessary a stage in the process as the two preceding ones. What you have to do at this time, apparently, is to turn the problem over to your unconscious mind and let it work while you sleep.
  • [W]hen you reach this third stage in the production of an idea, drop the problem completely and turn to whatever stimulates your imagination and emotions. Listen to music, go to the theater or movies, read poetry or a detective story.
  • articulates the increasing importance of quality information filters in our modern information diet. This notion of gathering raw material is the first step in his outline of the creative process:
  • Young calls the last stage “the cold, gray dawn of the morning after,” when your newborn idea has to face reality: It requires a deal of patient working over to make most ideas fit the exact conditions, or the practical exigencies, under which they must work. And here is where many good ideas are lost. The idea man, like the inventor, is often not patient enough or practical enough to go through with this adapting part of the process. But it has to be done if you are to put ideas to work in a work-a-day world. Do not make the mistake of holding your idea close to your chest at this stage. Submit it to the criticism of the judicious. When you do, a surprising thing will happen. You will find that a good idea has, as it were, self-expanding qualities. It stimulates those who see it to add to it. Thus possibilities in it which you have overlooked will come to light.
  • what’s perhaps most interesting is the following note he made to the postscript of a reprint: From my own further experience in advertising, government, and public affairs I find no essential points which I would modify in the idea-producing process. There is one, however, on which I would put greater emphasis. This is as to the store of general materials in the idea-producer’s reservoir. […] I am convinced, however, that you gather this vicarious experience best, not when you are boning up on it for an immediate purpose, but when you are pursuing it as an end in itself.
