The Agency at the Center of America's Tech Fight With China - The New York Times - 0 views

  • The Bureau of Industry and Security, a division of the Commerce Department, wields significant power given its role in determining the types of technology that companies can export and that foreign businesses can have access to.
  • American industry has held too much sway over the bureau.
  • putting a hard-liner at the helm could backfire and harm U.S. national security by starving American industry of revenue it needs to stay on the cutting edge of research and encouraging it to relocate offshore.
  • ...12 more annotations...
  • The bureau’s powers became clear during the Trump administration, which wielded its authority aggressively, though somewhat erratically, using the agency to curb exports of advanced technology goods like semiconductors to the telecommunications company Huawei and other Chinese businesses.
  • The Biden administration is still carrying out a review of its China policies and has not indicated how it plans to use the bureau’s powers.
  • They have an overall goal to become the leading country in the world, the wealthiest country in the world and the most powerful country in the world. That’s not going to happen on my watch because the United States are going to continue to grow and expand.”
  • That includes how to use the Commerce Department’s powers, including whether to block more exports of American technology, whether to keep or scrap Mr. Trump’s tariffs on foreign metals, and how to set the standards for national security reviews of foreign investments.
  • “China is the only country with the economic, diplomatic, military, and technological power to seriously challenge the stable and open international system — all the rules, values, and relationships that make the world work the way we want it to,”
  • Congress updated its laws governing export controls, giving the Bureau of Industry and Security more power to determine what kind of emerging technologies cannot be shared with China and other geopolitical rivals.
  • It’s that these guys have been trained for 30 years to think that exports are good for America and that’s that,” Mr. Scissors said. “So surprise, they don’t want tighter export controls.”
  • “The sense of urgency in recent years inclined our leadership to make decisions without reference to what industry thought,
  • the Biden administration is considering candidates to lead the Bureau of Industry and Security.
  • Mr. Wolf, who was previously assistant secretary at the bureau, issued the sanctions against ZTE. He has consistently argued that restrictions that are unclear and unpredictable can backfire, “harming the very interests they were designed to protect.”
  • The administration may also be considering less prominent candidates for the bureau’s three Senate-confirmed posts,
  • Whoever leads the bureau, officials at the National Security Council are likely to play a guiding role, according to people familiar with the deliberations.

FaceApp helped a middle-aged man become a popular younger woman. His fan base has never been bigger - The Washington Post - 1 views

  • 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.

Opinion | He's a Famous Evangelical Preacher, but His Kids Wish He'd Pipe Down - The New York Times - 1 views

  • He’s a Famous Evangelical Preacher, but His Kids Wish He’d Pipe Down
  • The Rev. Rick Joyner has called on Christians to arm themselves for civil war. But his children would be on the other side.
  • The Rev. Rick Joyner is a famous evangelical leader who has called on Christians to arm themselves for an inevitable civil war against liberals, whom he suggests are allies of the devil.
  • ...23 more annotations...
  • But this is the awkward part: His five children would be on the other side of that civil war, as he and his kids all acknowledge
  • She worries that his far-right rhetoric may get people killed, so she feels a responsibility to challenge him.
  • “He talks about Democrats being evil, forgetting that all five of his kids vote Democratic,”
  • “Who is he asking his followers to take up arms against? Liberal activists? That’s me.”
  • Just as America is torn asunder by politics and polarization, so is the Joyner family.
  • “I hope my kids don’t get involved in the violence, but it’s coming,”
  • “I think what he does is morally wrong, but I love him,”
  • “I don’t want to hurt him, but when he’s spreading dangerous ideas, it gets complicated.”
  • “One of my goals as a parent was to raise strong, independent children,”
  • “But I think I overshot the runway.
  • “I think it’s completely possible that some of my dad’s followers could pick up guns and cause violence because they think they’re defending the country,”
  • He claims liberals are in league with Satan and Democrats are plotting “to criminalize Christianity.”
  • Joyner’s rants leave his children furiously texting back and forth in exasperation (they say their mom is somewhere in the middle).
  • “There is a responsibility to hold those you love accountable,”
  • But how? The siblings disagree among themselves.
  • “I’m not willing to sacrifice my relationship with him to call him out.”
  • The most outspoken is Anna Jane, who says her father’s rhetoric became more extreme in recent years. She had her first falling out with him when she became a Democrat and an environmentalist while a sophomore at the University of North Carolina at Chapel Hill. He cut off her college funding, and she moved to New Zealand. Soon after, she nearly died in a boating accident — and the first person she called was her dad. They reconciled.
  • He also promoted a film by his son Ben about a gay man in the South, even though it likewise had him gritting his teeth.
  • “The church in America has been tremendously weakened,”
  • At what point can I no longer go home for Thanksgiving and watch football with my dad?” Ben mused. “By doing so, am I condoning his behavior? It can be hard to draw that line in the sand, especially when you love this person.”
  • “Is it OK to just talk about movies and dogs with someone who’s trying to incite civil war? I don’t know.”
  • She was furious at her father for his climate denial — but he’s the person she called in that crisis, and he stayed on the phone with her for much of the night, relaying the latest information and helping to keep her safe.
  • “I’m so angry at him for his politics and for endangering me and all of us by not believing in climate change,” she said. “And yet he’s the one I turn to in the middle of the night when I’m evacuating and I’m really scared.”

Anxiety, loneliness and Fear of Missing Out: The impact of social media on young people's mental health | Centre for Mental Health - 0 views

  • By 2021, it is forecast that there will be around 3 billion active monthly users of social media. From the statistics alone, it’s clear that social media has become an integral (and to a large extent, unavoidable) part of our lives.
  • One implication of social media’s rapid rise, that of its relationship with young people’s mental health, has gathered a significant amount of attention in recent years.
  • So-called ‘social media addiction’ has been referred to by a wide variety of studies and experiments. It is thought that addiction to social media affects around 5% of young people, and was recently described as potentially more addictive than alcohol and cigarettes
  • ...8 more annotations...
  • The ‘urge’ to check one’s social media may be linked to both instant gratification (the need to experience fast, short term pleasure) and dopamine production (the chemical in the brain associated with reward and pleasure).
  • The popular concept of Fear of Missing Out (FOMO) refers to ‘a pervasive apprehension that others might be having rewarding experiences from which one is absent’ and is ‘characterised by the desire to stay continually connected with what others are doing’.
  • Data from qualitative studies has shown that using social media compulsively can damage sleeping patterns, having an adverse effect on young people’s performance in school
  • The University of Glasgow found that young people found it difficult to relax following night time social media use, reducing their brain’s ability to prepare for sleep. Sleep loss works in a vicious cycle of reinforcement with mental health; that is, that loss of sleep due to night time social media use can lead to poorer mental health, and poor mental health can lead to intense night time use and sleep loss
  • What is dangerous about this compulsive use is that, if gratification is not experienced, users may internalise beliefs that this is due to being ‘unpopular’, ‘unfunny’ etc. A lack of ‘likes’ on a status update may cause negative self-reflection, prompting continual ‘refreshing’ of the page in the hope of seeing that another person has ‘enjoyed’ the post, thus helping to achieve personal validation.
  • FOMO has been linked to intensive social media use and is associated with lower mood and life satisfaction.
  • Social media has been linked to poor self-esteem and self-image through the advent of image manipulation on photo sharing platforms. In particular, the notion of the ‘idealised body image’ has arguably been detrimental to self-esteem and image, especially that of young women. The 24/7 circulation of easily viewable manipulated images promotes and entrenches unrealistic expectations of how young people should look and behave.
  • The evidence suggests that social media use is strongly associated with anxiety, loneliness and depression

  • Sometimes this means buying an alarm clock and putting your phone in a different room/closet than the one where you sleep. 
  • Ask for help
  • Who profits from my fear, my elation, my outrage? It’s a nice question to keep in the back of one’s head when you’re down the rabbit hole—especially when you’re not really getting much out of it, but just half-remembered ideas about what you’re reading and why.

Colleges are eliminating sports teams - and runners and golfers are paying more of a price than football or basketball players - 0 views

  • Since COVID-19 emerged, dozens of colleges and universities have announced the elimination of different intercollegiate athletics teams.
  • But the majority of closures came at regional and local campuses that participate in the NCAA’s Division II and Division III, or the National Association of Intercollegiate Athletics. Also, around 30 teams were eliminated by community colleges.
  • The 78 schools we examined spend around $87 million a year to keep all those teams going.
  • ...7 more annotations...
  • Most university administrators don’t expect their athletics programs to make a lot of money. Only about 25 of the 1,100 NCAA member schools’ athletics departments generate a profit.
  • public universities with NCAA Division I football teams received about 6% more in state funding annually than other institutions.
  • Many colleges and universities depend on varsity sports – like rowing, track and swimming – to attract more students to attend.
  • Most students who play college sports – including all of those at Division III and Ivy League programs – are not on an athletic scholarship.
  • Playing sports can also help with the transition into college. An intercollegiate team provides a ready-made social group that can help the new team member adjust to their new school.
  • Research also shows that hiring managers value college sports experience
  • The financial savings for athletics departments are immediate and obvious. But a longer-term impact will be seen on enrollment, campus life and the communities where colleges are located.

St Patrick's day: why so many US presidents like to say 'I'm Irish' - 0 views

  • Biden is the most strongly identified Irish-American in the White House since John F Kennedy, the only other Catholic president.
  • rish nationalist sentiments run high in the US, especially among its large diaspora. US presidents frequently indulge these views, at least symbolically. But, in practical terms, they have had little impact on the US-UK relationship.
  • More than 30 million people in the US – about one in ten Americans – identify as “Irish”.
  • ...6 more annotations...
  • there are over six times as many people in the US who claim to be Irish in the US as those living in the Republic of Ireland itself.
  • If measured by when their last ancestor left Ireland, Joe Biden is no more Irish than Barack Obama
  • Perhaps the most dramatic example of this was shown by Jimmy Carter, who – on St Patrick’s Day 1976 – marched down Fifth Avenue in New York wearing a badge emblazoned with the slogan “England, get out of Ireland”.
  • With Donald Trump being the exception, nearly every president of the last half-century has identified as “Irish”, even when the evidence of such a link has been tenuous.
  • In spite of this, US presidential administrations have sought a more balanced approach. The US considers the UK to be one of its most valuable and important strategic partners. US presidents work closely with British governments, while also offering symbolic affirmation for Ireland.
  • While Biden’s personal affinities are clear, we should expect him to follow his predecessors in placing US security interests before Irish nationalist affections.

'Social recession': how isolation can affect physical and mental health | Coronavirus | The Guardian - 0 views

  • Long-term, isolation even increases the risk of premature death. It’s being called a “social recession”
  • “People who are more socially connected show less inflammation, conversely people who are more isolated and lonely show increased chronic inflammation.
  • “Loneliness increases earlier death by 26%, social isolation by 29% and living alone by 32%.”
  • ...6 more annotations...
  • The risk of every cause of death – including heart disease, cancer, stroke, renal failure – increased from isolation.
  • One of the reasons people can suffer in social isolation is because personal relationships can help us cope with stress,
  • “For instance: the ongoing uncertainty of what’s going on right now in the world, your body’s response to that may differ. Depending on the extent to which you feel like you have the resources you need to cope with that. And that in large part may be dependent on whether or not you feel like you have others in your life you can rely on.
  • “We have evolved to be social creatures. For all the history of humanity, people have been in family structures, people have been in groups, we’re evolved to kind of crave and rely on that interaction with other human beings,”
  • “So when we don’t have that it’s a huge void in the way that we go about being human. This is something that has been kind of hard-wired into who we are as beings.”
  • people do at least have a wealth of options to stay connected. Texting, video calling or even the phone could potentially help avert the sense of isolation or loneliness, Khullar said.

'Drug Use For Grown-Ups' Serves As An Argument For Personal Choice : NPR - 0 views

  • In his new book Drug Use for Grown-Ups, the Columbia University professor of psychology and psychiatry zealously argues that drug use should be a matter of personal choice
  • personal choice can lead to positive outcomes.
  • "The practice spread widely...Many women and young girls, as also young men of respectable family, were being induced to visit the dens, where they were ruined morally and otherwise."
  • ...14 more annotations...
  • Soon enough, however, articles appeared widely that tried to make a connection between African American cocaine use and criminality.
  • one of the book's most eye-opening aspects is its challenge of the long-running association between drugs and addiction.
  • It must also interfere with a person's job, parenting or personal relationships. Other indications of addiction may be high tolerance, withdrawal symptoms, or persistence in repeated failed efforts to quit.
  • "What about the notion that drugs led to poverty and crime in my neighborhood?" he asks. "Well, that is simply an ugly fantasy, an incredibly effective one to be sure.
  • that it's a pre-existing kind of personal vulnerability — psychological and/or circumstantial — that precedes the drugs themselves that can lead to addiction.
  • And when addiction does occur, there should be safe spaces for people to get help,
  • There are no cures in psychiatric medicine. We don't have a cure for depression, nor do we have a cure for schizophrenia or anxiety.
  • We merely have medications and therapies that treat symptoms, and this allows patients to function better, despite their illnesses."
  • "such issues affect only 10 percent to 30 percent of those who use even the most stigmatized drugs, such as heroin or methamphetamine."
  • but also because it seemingly provides a simple solution to complicated problems faced by poor and desperate people.
  • But he also so importantly emphasizes that anti-drug laws have disproportionately ruined the lives of people of color;
  • Drug Use for Grown-Ups makes the case for people having the right to use drugs if they want to.
  • What we have now, instead, is racist mass incarceration and social shame prevailing (and drugs hardly scarce anyway).

Accurate machine learning in materials science facilitated by using diverse data sources - 0 views

  • Computational modelling is also used to estimate the properties of materials. However, there is usually a trade-off between the cost of the experiments (or simulations) and the accuracy of the measurements (or estimates), which has limited the number of materials that can be tested rigorously.
  • Materials scientists commonly supplement their own ‘chemical intuition’ with predictions from machine-learning models, to decide which experiments to conduct next
  • More importantly, almost all of these studies use models built on data obtained from a single, consistent source. Such models are referred to as single-fidelity models.
  • ...4 more annotations...
  • However, for most real-world applications, measurements of materials’ properties have varying levels of fidelity, depending on the resources available.
  • A comparison of prediction errors clearly demonstrates the benefit of the multi-fidelity approach
  • The authors’ system is not restricted to materials science, but is generalizable to any problem that can be described using graph structures, such as social networks and knowledge graphs (digital frameworks that represent knowledge as concepts connected by relationships)
  • More research is needed to understand the scenarios for which multi-fidelity learning is most beneficial, balancing prediction accuracy with the cost of acquiring data

How Isaac Newton Changed the World | Live Science - 0 views

  • To the probable dismay of some befuddled calculus and physics students the world over, Isaac Newton didn't just live, he grew up and lived long enough to become the single-most influential scientist of the 17th-century.
  • Newton's wide range of discoveries, from his theories of optics to his groundbreaking work on the laws of motion and gravity, formed the basis for modern physics.
  • The true genius of his work, experts think, is how he ultimately took those theories and applied them to the universe at large, explaining the motions of the Sun and planets in a way that had never been done before.
  • ...6 more annotations...
  • Upon getting bumped on the head by a falling apple, Newton airily dreams up the laws of gravity and the rest, as they say, is history
  • When the black plague closed Cambridge University, where he was a student, for two years starting in 1665, he spent the long months locked up at home studying complex mathematics, physics and optics.
  • It was during this fruitful time that Newton, with the help of a crystal prism, became the first to discover that white light is made up a spectrum of colors
  • He also developed the concept of infinite-series calculus, the kind of scary math studied today by engineering and statistics scholars.
  • By 1666, Newton had even laid the blueprints for his three laws of motion, still recited by physics students everywhere:An object will remain in a state of inertia unless acted upon by force.The relationship between acceleration and applied force is F=ma.For every action there is an equal and opposite reaction.
  • Across the pages of the Principia, Newton breaks down the workings of the solar system into "'simple"' equations, explaining away the nature of planetary orbits and the pull between heavenly bodies.

Why some people like wearing masks - BBC Worklife - 0 views

  • Some people welcome face coverings for reasons ranging from the convenient and expedient to the more complex and psychological. But is this a helpful coping mechanism?
  • Since I've been wearing the mask, my awkward interactions with friends and family have significantly reduced,” he says. Now, he goes to the shops whenever he wants, without worrying about whom he might see. He hopes that, even after the pandemic ends, it will still be socially acceptable to wear a mask.
  • Some welcome the way face coverings reduce or change interactions that might otherwise spark social anxiety. But is this a helpful coping mechanism – and what happens when the pandemic comes to an end?

  • They have ditched their old makeup and shaving routines and are saving money, time and stress. Others have discovered that hiding their mouths affords them unexpected freedoms. Some restaurant servers and retail workers say they no longer feel obliged to fake-smile at customers, potentially lifting the burden of emotional labour.
  • “During a pandemic, we’re under severe stress, and whether you’re worrying about your appearance or you’re worried about someone harassing you or whistling at you, the masks can provide a respite from those things that can occupy our mind when we’re out in public. You have more freedom to be meditating or thinking about whatever you want.”
  • “Anonymity carries power,” adds Ramani Durvasula, a clinical psychologist and psychology professor at California State University, Los Angeles. “It can feel like trying on a different ‘role’ and the associated expectations of that role, perhaps freeing us of what can feel exhausting and insincere about smiling (especially when we aren't having a good day).”
  • “For introverts, it can feel great that you don’t have to talk to people you don’t know that well, but in the long run, when you get out of your comfort zone and challenge yourself… [you might form] a really fulfilling or positive relationship,”
  • Think back to the last time you failed or made an important mistake. Do you still blush with shame, and scold yourself for having been so stupid or selfish? Do you tend to feel alone in that failure, as if you were the only person to have erred? Or do you accept that error is a part of being human, and try to talk to yourself with care and tenderness?
  • “Most of us have a good friend in our lives, who is kind of unconditionally supportive,” says Kristin Neff, an associate professor of educational psychology at the University of Texas at Austin, who has pioneered this research. “Self-compassion is learning to be that same warm, supportive friend to yourself.”

Jesse Watters and the Story of The Five's 'Mom Texts' - The Atlantic - 0 views

  • Many American families are in the political situation that the Watterses find themselves in, even if most families don’t work out their differences on TV. According to a survey conducted a year ago by the Public Religion Research Institute and The Atlantic, 39 percent of Americans said some political diversity exists within their family. And an ABC News survey found that the 2016 campaign made family relationships and friendships more tense for a roughly similar percentage of Americans.
  • My colleague Ashley Fetters wrote earlier this year about how family members might discuss their conflicting political views. Suggestions included “abandon[ing] the idea of winning an argument or convincing other people of the wrongness of their positions” and “deliberately distanc[ing] themselves from the full platform of policy positions supported by their chosen political party and instead examin[ing] each issue individually.

Andrew Sullivan: Is There a Way to Acknowledge Our Progress? - 0 views

  • ft of recent books have been full of the need for renewed rage against the oppression of women. The demonization of “white men” has intensified just as many working-class white men face a bleak economic future and as men are disappearing from the workforce. It is as if the less gender discrimination there is, the angrier you should become.
  • You see it in the gay-rights movement too. I get fundraising emails all the time reminding me how we live in a uniquely perilous moment for LGBTQ Americans and that this era, in the words of Human Rights Campaign spokesperson Charlotte Clymer, is one “that has seen unprecedented attacks on LGBTQ people.
  • Might I suggest some actual precedents: when all gay sex was criminal, when many were left by their government to die of AIDS, when no gay relationships were recognized in the law, when gay service members were hounded out of their mission, when the federal government pursued a purge of anyone suspected of being gay. All but the last one occurred in my adult lifetime. But today we’re under “unprecedented” assault?

  • a recent psychological study suggests a simpler explanation. Its core idea is what you might call “oppression creep” or, more neutrally, “prevalence-induced concept change.” The more progress we observe, the greater the remaining injustices appear.
  • We seem incapable of keeping a concept stable over time when the prevalence of that concept declines.
  • lthough modern societies have made extraordinary progress in solving a wide range of social problems, from poverty and illiteracy to violence and infant mortality, the majority of people believe that the world is getting worse. The fact that concepts grow larger when their instances grow smaller may be one source of that pessimism.
  • We see relatively, not absolutely. We change our standards all the time, depending on context.
  • When blue dots became rare, purple dots began to look blue; when threatening faces became rare, neutral faces began to appear threatening … This happened even when the change in the prevalence of instances was abrupt, even when participants were explicitly told that the prevalence of instances would change, and even when participants were instructed and paid to ignore these changes.
  • We seem to be wired to assume a given threat remains just as menacing even when its actual prevalence has declined:
  • “In other words, when the prevalence of blue dots decreased, participants’ concept of blue expanded to include dots that it had previously excluded.”
  • This study may help explain why, in the midst of tremendous gains for gays, women, and racial minorities, we still insist more than ever that we live in a patriarchal, misogynist, white supremacist, homophobic era.
  • whatever the cause, the result is that we steadfastly refuse to accept the fact of progress, in a cycle of eternal frustration at what injustices will always remain
  • We never seem to be able to say: “Okay, we’re done now, we’ve got this, politics has done all it reasonably could, now let’s move on with our lives.” We can only ever say: “It’s worse than ever!” And fe
  • picking someone who has bent the truth so often about so many things — her ancestry, her commitment to serving a full term as senator, the schools her kids went to, the job her father had (according to her brother), or the time she was “fired” for being pregnant — is an unnecessary burden.
  • The Democrat I think is most likely to lose to Trump is Elizabeth Warren.I admire her ambition and grit and aggression, but nominating a woke, preachy Harvard professor plays directly into Trump’s hands
  • Pete Buttigieg’s appeal has waned for me.

  • Klobuchar, to my mind, is the better midwestern option. She is an engaging and successful politician. But there’s a reason she seemingly can’t get more traction. She just doesn’t command a room
  • I so want Biden to be ten years younger. I can’t help but be very fond of the man, and he does have a mix of qualities that appeal to both African-Americans and white working-class midwesterners. What I worry about is his constant stumbling in his speech, his muddling of words, those many moments when his eyes close, and his face twitches, as he tries to finish a sentence
  • Sanders has been on the far left all his life, and the oppo research the GOP throws at him could be brutal. He’s a man, after all, who sided with a Marxist-Leninist party that supported Ayatollah Khomeini during the hostage crisis in 1979. He loved the monstrous dictator Fidel Castro and took his 1988 honeymoon in the Soviet Union, no less, where he openly and publicly criticized his own country and praised many aspects of the Soviet system
  • On two key issues, immigration and identity politics, Bernie has sensibilities and instincts that could neutralize these two strong points for Trump. Sanders has always loathed the idea of open borders and the effect they have on domestic wages, and he doesn’t fit well with the entire woke industry. He still believes in class struggle, not the culture war
  • Biden has an advantage because of Obama, his appeal to the midwestern voters (if he wins back Pennsylvania, that would work wonders), and his rapport with African-Americans. But he also seems pretty out of it.

Opinion | 2020 Taught Us How to Fix This - The New York Times - 0 views

  • So many of our hopes are based on the idea that the key to change is education.
    • anonymous
       
      This whole articles lets us question the very education that we learn how to think about thoughts from too.
  • Second, some researchers argue that the training activates stereotypes in people’s minds rather than eliminates them.
    • anonymous
       
      An interesting idea!
  • Fourth, the mandatory training makes many white participants feel left out, angry and resentful, actually decreasing their support for workplace diversity.

  • Fifth, people don’t like to be told what to think, and may rebel if they feel that they’re being pressured to think a certain way.

      We've talked about all this!
  • our training model of “teaching people to be good” is based on the illusion that you can change people’s minds and behaviors by presenting them with new information and new thoughts.

  • doing life together with people of other groups can reduce prejudice and change minds.

      Very true.
  • impervious to evidence, willing to believe the most outlandish things if it suited their biases
  • this was the year that called into question the very processes by which our society supposedly makes progress.
  • It turns out that if you tell someone their facts are wrong, you don’t usually win them over; you just entrench false belief.
  • this was the year that showed that our models for how we change minds or change behavior are deeply flawed.
  • The courses teach people about bias, they combat stereotypes and they encourage people to assume the perspectives of others in disadvantaged groups.
  • One of the most studied examples of this flawed model is racial diversity training
  • Our current model of social change isn’t working.
  • but the bulk of the evidence, though not all of it, suggests they don’t reduce discrimination.
  • One meta-analysis of 985 studies of anti-bias interventions found little evidence that these programs reduced bias. Other studies sometimes do find a short-term change in attitudes, but very few find a widespread change in actual behavior.
  • First, “short-term educational interventions in general do not change people.”
  • Third, training can make people complacent, thinking that because they went through the program they’ve solved the problem
