When Herbert Hoover talked about putting “a chicken in every pot,” chicken was a luxury: In 1930, whole dressed chicken retailed in the United States for $7 a pound in today’s dollars. In contrast, that Costco bird now sells for less than $2 a pound.

It’s not that Costco chickens suffer more than Walmart or Safeway birds. All are part of an industrial agricultural system that, at the expense of animal well-being, has become extremely efficient at producing cheap protein.

“They’re living on their own feces, with no fresh air and no natural light,” said Leah Garcés, the president of Mercy for Animals. “I don’t think it’s what a Costco customer expects.”

Garcés wants Costco to sign up for the “Better Chicken Commitment,” an industry promise to work toward slightly better standards for industrial agriculture. For example, each adult chicken would get at least one square foot of space, there would be some natural light and the company would avoid breeds that put on weight that the legs can’t support.

Burger King, Popeyes, Chipotle, Denny’s and some 200 other food companies have embraced the Better Chicken Commitment, but grocery chains generally have not, with the exception of Whole Foods.

Yet what struck me was that Costco completely accepts that animal welfare should be an important consideration. We may disagree about whether existing standards are adequate, but the march of moral progress on animal rights is unmistakable.

When I began writing about these issues, I never guessed that McDonald’s would commit to cage-free eggs, that California would legislate protections for mother pigs, that there would be court fights about whether an elephant has legal “personhood,” and that Pope Francis would suggest that animals go to heaven and that the Virgin Mary “grieves for the sufferings” of mistreated livestock.

I don’t pretend that there are neat solutions. We raised a flock of chickens on our family farm when I was a kid, and we managed to be neither efficient nor humane. Many birds died, and being eaten by a coyote wasn’t such a pleasant way to go, either. There’s no need for a misplaced nostalgia for traditional farming practices, just a pragmatic acknowledgment of animal suffering and trade-offs to reduce it.

We treat poultry particularly poorly because humans identify less with birds than with fellow mammals. We may empathize with a calf with big eyes, but less so with species that we dismiss as “bird brains.”

Still, the issue remains as the English philosopher Jeremy Bentham posed it in 1789: “The question is not, Can they reason?, nor Can they talk? but, Can they suffer?”

Administering a nationally representative phone survey with 1,008 respondents, they found that people who got most of their information from mainstream print and broadcast outlets tended to have an accurate assessment of the severity of the pandemic and their risks of infection.

But those who relied on conservative sources, such as Fox News and Rush Limbaugh, were more likely to believe in conspiracy theories or unfounded rumors, such as the belief that taking vitamin C could prevent infection, that the Chinese government had created the virus, and that the U.S. Centers for Disease Control and Prevention was exaggerating the pandemic’s threat “to damage the Trump presidency.”

“The effect that we measure could be driven by the long-term message of Fox News, which is that the mainstream media often report ‘fake news’ and have a political agenda,” Simonov said. “This could result in lowering trust in institutions and experts, including health experts in the case of the pandemic.”

Our results indicate that a one standard deviation increase in relative viewership of Hannity relative to Tucker Carlson Tonight is associated with approximately 32 percent more COVID-19 cases on March 14 and approximately 23 percent more COVID-19 deaths on March 28,

“If the results hold, the research demonstrates the influence that broadcast media can have on behavior,”

The second finding is de novo point mutations, which arise spontaneously in the sperm of adult men. Sperm divide every 15 days. This continuous division and copying of DNA leads to errors, and the rate of error increases significantly with age: a 20-year-old will have an average of 25 de novo point mutations in his sperm, whereas a 40-year-old will have 65. These mutations are one reason older fathers are more likely to have children with autism and schizophrenia.

“It is hard to look at increasing trends in media consumption of all types, media multitasking and rates of ADHD in young people and not conclude that there is a decrease in their attention span,

Emerging research suggests that watching short, fast-paced videos makes it harder for kids to sustain activities that don’t offer instant—and constant—gratification.

One of the few studies specifically examining TikTok-related effects on the brain focused on Douyin, the TikTok equivalent in China, made by the same Chinese parent company, ByteDance Ltd. It found that the personalized videos the app’s recommendation engine shows users activate the reward centers of the brain, as compared with the general-interest videos shown to new users.

Brain scans of Chinese college students showed that areas involved in addiction were highly activated in those who watched personalized videos.

It also found some people have trouble controlling when to stop watching.

attention. “If kids’ brains become accustomed to constant changes, the brain finds it difficult to adapt to a nondigital activity where things don’t move quite as fast,”

A TikTok spokeswoman said the company wants younger teens to develop positive digital habits early on, and that it recently made some changes aimed at curbing extensive app usage. For example, TikTok won’t allow users ages 13 to 15 to receive push notifications after 9 p.m. TikTok also periodically reminds users to take a break to go outside or grab a snack.

Kids have a hard time pulling away from videos on YouTube, too, and Google has made several changes to help limit its use, including turning off autoplay by default on accounts of people under 18.

When kids do things that require prolonged focus, such as reading or solving math problems, they’re using directed attention

This function starts in the prefrontal cortex, the part of the brain responsible for decision making and impulse control.

“Directed attention is the ability to inhibit distractions and sustain attention and to shift attention appropriately. It requires higher-order skills like planning and prioritizing,”

Kids generally have a harder time doing this—and putting down their videogame controllers—because the prefrontal cortex isn’t fully developed until age 25.

“We speculate that individuals with lower self-control ability have more difficulty shifting attention away from favorite video stimulation,

“In the short-form snackable world, you’re getting quick hit after quick hit, and as soon as it’s over, you have to make a choice,” said Mass General’s Dr. Marci, who wrote the new book “Rewired: Protecting Your Brain in the Digital Age.” The more developed the prefrontal cortex, the better the choices.

Dopamine is a neurotransmitter that gets released in the brain when it’s expecting a reward. A flood of dopamine reinforces cravings for something enjoyable, whether it’s a tasty meal, a drug or a funny TikTok video.

“TikTok is a dopamine machine,” said John Hutton, a pediatrician and director of the Reading & Literacy Discovery Center at Cincinnati Children’s Hospital. “If you want kids to pay attention, they need to practice paying attention.”

Researchers are just beginning to conduct long-term studies on digital media’s effects on kids’ brains. The National Institutes of Health is funding a study of nearly 12,000 adolescents as they grow into adulthood to examine the impact that many childhood experiences—from social media to smoking—have on cognitive development.

she predicts they will find that when brains repeatedly process rapid, rewarding content, their ability to process less-rapid, less-rewarding things “may change or be harmed.”

“It’s like we’ve made kids live in a candy store and then we tell them to ignore all that candy and eat a plate of vegetables,”

“We have an endless flow of immediate pleasures that’s unprecedented in human history.”

Parents and kids can take steps to boost attention, but it takes effort

Swap screen time for real time. Exercise and free play are among the best ways to build attention during childhood,

“Depriving kids of tech doesn’t work, but simultaneously reducing it and building up other things, like playing outside, does,”

Practice restraint.

“When you practice stopping, it strengthens those connections in the brain to allow you to stop again next time.”

Use tech’s own tools. TikTok has a screen-time management setting that allows users to cap their app usage.

What happens inside a person’s head can have damaging effects throughout the body, as well as the other way around. An untreated mental illness can significantly increase the risk of becoming physically ill, and physical disorders may result in behaviors that make mental conditions worse.

In studies that tracked how patients with breast cancer fared, for example, Dr. David Spiegel and his colleagues at Stanford University School of Medicine showed decades ago that women whose depression was easing lived longer than those whose depression was getting worse. His research and other studies have clearly shown that “the brain is intimately connected to the body and the body to the brain,”

“The body tends to react to mental stress as if it was a physical stress.”

Anxiety disorders affect nearly 20 percent of American adults. That means millions are beset by an overabundance of the fight-or-flight response that primes the body for action.

“We often talk about depression as a complication of chronic illness,” Dr. Frownfelter wrote in Medpage Today in July. “But what we don’t talk about enough is how depression can lead to chronic disease. Patients with depression may not have the motivation to exercise regularly or cook healthy meals. Many also have trouble getting adequate sleep.”

These protective actions stem from the neurotransmitters epinephrine and norepinephrine, which stimulate the sympathetic nervous system and put the body on high alert. But when they are invoked too often and indiscriminately, the chronic overstimulation can result in all manner of physical ills, including digestive symptoms like indigestion, cramps, diarrhea or constipation, and an increased risk of heart attack or stroke.

While it’s normal to feel depressed from time to time, more than 6 percent of adults have such persistent feelings of depression that it disrupts personal relationships, interferes with work and play, and impairs their ability to cope with the challenges of daily life

“Depression diminishes a person’s capacity to analyze and respond rationally to stress,” Dr. Spiegel said. “They end up on a vicious cycle with limited capacity to get out of a negative mental state.”

Although persistent anxiety and depression are highly treatable with medications, cognitive behavioral therapy and talk therapy, without treatment these conditions tend to get worse.

When you’re stressed, the brain responds by prompting the release of cortisol, nature’s built-in alarm system. It evolved to help animals facing physical threats by increasing respiration, raising the heart rate and redirecting blood flow from abdominal organs to muscles that assist in confronting or escaping danger.

Improving sleep is especially helpful, Dr. Spiegel said, because “it enhances a person’s ability to regulate the stress response system and not get stuck in a mental rut.”

“When inequality increases, people with high incomes don’t benefit much from their gains – many rich people are focused on those who have even more than they do, and they never feel they have enough,”

“But people who earn little really suffer from falling further behind – they feel excluded and frustrated by not being able to keep up even with people who receive average incomes.”

examined survey data of life satisfaction levels, where people rate their life satisfaction on a scale of one to 10, and linked it to Gini coefficient numbers – a measure of inequality – from 1981 to 2020.

his study of 78 countries spanning four decades – the largest longitudinal research of its kind – punctures that myth

However, as measures to reduce inequality began to take effect, happiness slowly returned so that by 2018, life satisfaction stood at 7.8.

Any country that moved from the lowest quarter of countries in terms of inequality to the highest quarter saw a decrease in life satisfaction of about 0.4 on the 10-point scale, he found.

India’s life satisfaction declined from 6.7 in 1990 to 5.8 in 2006 as inequality rose. By 2012 it was still lower than in 1990, despite the country’s prolonged economic boom.

The US and Australia also both saw pronounced falls in life satisfaction, but those countries where inequality had fallen were generally happier, such as Poland, Peru, Mexico and Ukraine, before the Russian invasion.

“In some of the previous research, you see people saying ‘inequality isn’t that big a deal, so all efforts to address inequality are misguided because inequality is beneficial’.

“I think that’s misguided – inequality is generally damaging to people’s life satisfaction so we should pay attention to efforts to mitigate it,

41% of those who said to have fair to expert levels of cryptocurrency knowledge said they were very likely to purchase BTC in the next 12 months, compared with just 7.9% of those with limited to no knowledge of the topic.

Unions are among the most effective mechanisms available for addressing massive economic inequalities. Congress should adopt labor law reforms to better protect workers' right to organize, starting with the widely popular Protecting the Right to Organize (PRO) Act. Among other things, the PRO Act would create the first serious monetary penalties for employers that retaliate against workers for unionizing.

Congress must also adequately fund the National Labor Relations Board (NLRB) so the agency can enforce labor law.

Many US workers say they want a union, but far too few have one. Right now, workers who've won recent union elections are inviting employers to meet them as equals and start bargaining union contracts.

Labor unions are highly correlated with safer conditions because they give workers a voice in setting workplace policies and the ability to engage management in addressing concerns without fear of retaliation.

The Black-led, multiracial committees that have led organizing drives at Amazon warehouses and the young women baristas leading breakthrough organizing victories at Starbucks are changing the public face of the labor movement in powerful and promising ways.

Two-thirds of union workers are women and/or workers of color.

In any company, the transparency and consistency of a union contract that sets wage rates, scheduled raises and procedures for promotions helps guard against forms of discriminatory bias that otherwise disadvantage women and workers of color.

Unionizing workers will continue to need extraordinary solidarity, persistence and public support in order to succeed. This is a moment of opportunity for all of us. Anyone ready to start reversing the worst economic inequalities the US has seen in almost a century can choose now to join and support workers who are organizing unions.

To beat confirmation bias, it’s vital for brands to face reality when measuring the success of their campaigns and gauging customer brand perception.

As a marketer, it can be easy to fall victim to simply measuring customer behavioural data (like click-through rates, ad engagement, unsubscribes, etc.). However, the best marketing teams lean on an outside-in perspective to improve customer experiences and create a better brand reputation.

Additionally, marketing teams would be wise to connect with potential customers who did not convert. They will be most able to point out the pain points in a marketing campaign that are dissuading buyers. It’s just as important to ask consumers why they didn’t interact with a brand as it is to ask why they do.

Obtaining these insights allows marketers to gauge specifics into how their competitors are beating them out, and conversely, how they can improve their product and boost customer retention.

At the end of the day, customers want to know that their feedback is valued and has the power to drive change. Companies that choose to neglect customer feedback are prime examples of the dangers of confirmation bias.

It doesn’t matter how marketing teams or their company define success, it’s up to the customer.

For example, in industries like video tech and security, where the community is extremely tight knit, marketing teams must have a deep understanding of their audience’s business needs to have any chance of selling to them. Brands that understand consumer perception and needs, will be able to personalize messages to their target audience and create a more positive customer experience. By gauging and adapting to direct feedback, marketing teams can avoid the dangers of confirmation bias, and make wholesale changes that will turn customers into brand champions.

Senate Republicans have for years blocked progress on any gun safety legislation. They opposed efforts to tighten gun regulations both when they held the majority, and even now when they can threaten an indefinite filibuster if Democrats can’t come up with the 60 votes required to circumvent the stalling tactic.

“It’s much easier to scream about guns than it is to demand answer about where our culture is failing,” Cruz added in a separate social media post on Saturday.

Disapproval from Cruz and other Senate Republicans will likely doom any legislation Nadler and other House Democrats manage to pass.

Democrats dispute the claim that lawmakers need to target mental illness more so than the availability of guns to reduce shooting violence in the U.S. They say that similar rates of mental illness in other developed nations across the globe prove that mental illness alone cannot fully explain the prevalence of mass shootings in the U.S.

In general, one of the problems with treating depression “is that we’ve got a lot of medications that pretty much do the same thing,” Dr. Aaronson said. And when patients do not respond to those medications, “we don’t have a lot of novel stuff.”

The activity of the vagus nerve is difficult to measure directly, especially given how complex it is. But because some vagus nerve fibers connect with the heart, experts can indirectly measure cardiac vagal tone — or the way in which your nervous system regulates your heart — by looking at your heart rate variability, which are the fluctuations in the amount of time between your heartbeats, on an EKG.

Holding your breath and submerging your face in cold water can trigger the “diving reflex,” a response that slows the heart beat and constricts blood vessels. Some people who have tried it report that it has a calming effect and can even reduce insomnia. Others wrap an ice pack in cloth and place it on their chest to relieve anxiety.

“For wellness, try to maintain high vagus nerve activity through mindfulness, exercise and paced breathing,” Dr. Tracey said. “These are all very good for you.”

Olli-Pekka Heinonen, director-general of the IB, told The Times that teenagers taking the new diploma would be “uniquely empowered” on leaving school.

Traditional assessment often led to pupils forgetting what they had learnt once exams were over, he said. “The aim of this type of assessment is to strengthen deep learning and understanding, something you learn that stays with you and is part of you. We’re experimenting with non-exam assessment and finding the best ways to evaluate.

“Biodiversity, food, migration and energy are meaningful and attractive to young people. They’re appealing and relevant.“We’re looking at these areas through the lens of systems leadership — ie, how it’s possible to make change happen.”

The school hosts pupils from 80 different countries and charges fees of £37,000 a year. It is set in St Donat’s Castle, in 122 acres and its grounds include woodland, farmland, a valley and its own seafront.

Naheed Bardai, principal of UWC Atlantic, said he felt dissatisfied with the state of education in the world today as pupils should be prepared to become leaders of organisations and government in the 2040s and 2050s.

He said the new qualification would help them understand the root causes of problems but also become compassionate world leaders that can create “transformative solutions”.

“Our core policies are peace, sustainability and experiential learning but there’s very little education for young people at the intersection of problems, particularly where the human meets the natural world,”

We need people who can take constructive action as inequality is growing at a tremendous rate.”

Bardai said the school had been given a free hand in curriculum writing and was looking at more radical forms of assessment. This may include interviews, peer assessment and portfolios.

Some are motivated by potential business revenue, others by national security concerns.

Sometimes, they trade letters, opinion essays or social threads outlining their positions and attacking others’ in public view. More often, they tout their viewpoints without acknowledging alternatives, leaving the impression that their enlightened perspective is the inevitable lens through which to view A.I.

you’ll realize this isn’t really a debate only about A.I. It’s also a contest about control and power, about how resources should be distributed and who should be held accountable.

It is critical that we begin to recognize the ideologies driving what we are being told. Resolving the fracas requires us to see through the specter of A.I. to stay true to the humanity of our values.

Because language itself is part of their battleground, the different A.I. camps tend not to use the same words to describe their positions

One faction describes the dangers posed by A.I. through the framework of safety, another through ethics or integrity, yet another through security and others through economics.

The Doomsayers

These are the A.I. safety people, and their ranks include the “Godfathers of A.I.,” Geoff Hinton and Yoshua Bengio. For many years, these leading lights battled critics who doubted that a computer could ever mimic capabilities of the human mind

Many doomsayers say they are acting rationally, but their hype about hypothetical existential risks amounts to making a misguided bet with our future

Reasonable sounding on their face, these ideas can become dangerous if stretched to their logical extremes. A dogmatic long-termer would willingly sacrifice the well-being of people today to stave off a prophesied extinction event like A.I. enslavement.

The technology historian David C. Brock calls these fears “wishful worries” — that is, “problems that it would be nice to have, in contrast to the actual agonies of the present.”

OpenAI’s Sam Altman and Meta’s Mark Zuckerberg, both of whom lead dominant A.I. companies, are pushing for A.I. regulations that they say will protect us from criminals and terrorists. Such regulations would be expensive to comply with and are likely to preserve the market position of leading A.I. companies while restricting competition from start-ups

the roboticist Rodney Brooks has pointed out that we will see the existential risks coming, the dangers will not be sudden and we will have time to change course.

While we shouldn’t dismiss the Hollywood nightmare scenarios out of hand, we must balance them with the potential benefits of A.I. and, most important, not allow them to strategically distract from more immediate concerns.

The Reformers

While the doomsayer faction focuses on the far-off future, its most prominent opponents are focused on the here and now. We agree with this group that there’s plenty already happening to cause concern: Racist policing and legal systems that disproportionately arrest and punish people of color. Sexist labor systems that rate feminine-coded résumés lower

Superpower nations automating military interventions as tools of imperialism and, someday, killer robots.

Propagators of these A.I. ethics concerns — like Meredith Broussard, Safiya Umoja Noble, Rumman Chowdhury and Cathy O’Neil — have been raising the alarm on inequities coded into A.I. for years. Although we don’t have a census, it’s noticeable that many leaders in this cohort are people of color, women and people who identify as L.G.B.T.Q.

Others frame efforts to reform A.I. in terms of integrity, calling for Big Tech to adhere to an oath to consider the benefit of the broader public alongside — or even above — their self-interest. They point to social media companies’ failure to control hate speech or how online misinformation can undermine democratic elections. Adding urgency for this group is that the very companies driving the A.I. revolution have, at times, been eliminating safeguards

reformers tend to push back hard against the doomsayers’ focus on the distant future. They want to wrestle the attention of regulators and advocates back toward present-day harms that are exacerbated by A.I. misinformation, surveillance and inequity.

Integrity experts call for the development of responsible A.I., for civic education to ensure A.I. literacy and for keeping humans front and center in A.I. systems.

Surely, we are a civilization big enough to tackle more than one problem at a time; even those worried that A.I. might kill us in the future should still demand that it not profile and exploit us in the present.

Other groups of prognosticators cast the rise of A.I. through the language of competitiveness and national security.

Some arguing from this perspective are acting on genuine national security concerns, and others have a simple motivation: money. These perspectives serve the interests of American tech tycoons as well as the government agencies and defense contractors they are intertwined with.

they appear deeply invested in the idea that there is no limit to what their creations will be able to accomplish.

U.S. megacompanies pleaded to exempt their general purpose A.I. from the tightest regulations, and whether and how to apply high-risk compliance expectations on noncorporate open-source models emerged as a key point of debate. All the while, some of the moguls investing in upstart companies are fighting the regulatory tide. The Inflection AI co-founder Reid Hoffman argued, “The answer to our challenges is not to slow down technology but to accelerate it.”

The warriors’ narrative seems to misrepresent that science and engineering are different from what they were during the mid-20th century. A.I. research is fundamentally international; no one country will win a monopoly.

As the science-fiction author Ted Chiang has said, fears about the existential risks of A.I. are really fears about the threat of uncontrolled capitalism

Regulatory solutions do not need to reinvent the wheel. Instead, we need to double down on the rules that we know limit corporate power. We need to get more serious about establishing good and effective governance on all the issues we lost track of while we were becoming obsessed with A.I., China and the fights picked among robber barons.

By analogy to the health care sector, we need an A.I. public option to truly keep A.I. companies in check. A publicly directed A.I. development project would serve to counterbalance for-profit corporate A.I. and help ensure an even playing field for access to the 21st century’s key technology while offering a platform for the ethical development and use of A.I.

Also, we should embrace the humanity behind A.I. We can hold founders and corporations accountable by mandating greater A.I. transparency in the development stage, in addition to applying legal standards for actions associated with A.I. Remarkably, this is something that both the left and the right can agree on.

Diamond and Dybvig offered a stylized but insightful model of what banks do. They argued that there is always a tension between individuals’ desire for liquidity — ready access to funds — and the economy’s need to make long-term investments that can’t easily be converted into cash.

Banks square that circle by taking money from depositors who can withdraw their funds at will — making those deposits highly liquid — and investing most of that money in illiquid assets, such as business loans.

So banking is a productive activity that makes the economy richer by reconciling otherwise incompatible desires for liquidity and productive investment. And it normally works because only a fraction of a bank’s depositors want to withdraw their funds at any given time.

This does, however, make banks vulnerable to runs. Suppose that for some reason many depositors come to believe that many other depositors are about to cash out, and try to beat the pack by withdrawing their own funds. To meet these demands for liquidity, a bank will have to sell off its illiquid assets at fire sale prices, and doing so can drive an institution that should be solvent into bankruptcy

If that happens, people who didn’t withdraw their funds will be left with nothing. So during a panic, the rational thing to do is to panic along with everyone else.

There was, of course, a huge wave of banking panics in 1930-31. Many banks failed, and those that survived made far fewer business loans than before, holding cash instead, while many families shunned banks altogether, putting their cash in safes or under their mattresses. The result was a diversion of wealth into unproductive uses. In his 1983 paper, Bernanke offered evidence that this diversion played a large role in driving the economy into a depression and held back the subsequent recovery.

In the story told by Friedman and Anna Schwartz, the banking crisis of the early 1930s was damaging because it led to a fall in the money supply — currency plus bank deposits. Bernanke asserted that this was at most only part of the stor

a government backstop — either deposit insurance, the willingness of the central bank to lend money to troubled banks or both — can short-circuit potential crises.

Such arrangements offered a higher yield than conventional deposits. But they had no safety net, which opened the door to an old-style bank run and financial panic.

So banks need to be regulated as well as backstopped. As I said, the Diamond-Dybvig analysis had remarkably large implications for policy.

From an economic point of view, banking is any form of financial intermediation that offers people seemingly liquid assets while using their wealth to make illiquid investments.

This insight was dramatically validated in the 2008 financial crisis.

By the eve of the crisis, however, the financial system relied heavily on “shadow banking” — banklike activities that didn’t involve standard bank deposits

But providing such a backstop raises the possibility of abuse; banks may take on undue risks because they know they’ll be bailed out if things go wrong.

And the panic came. The conventionally measured money supply didn’t plunge in 2008 the way it did in the 1930s — but repo and other money-like liabilities of financial intermediaries did:

Fortunately, by then Bernanke was chair of the Federal Reserve. He understood what was going on, and the Fed stepped in on an immense scale to prop up the financial system.

a sort of meta point about the Diamond-Dybvig work: Once you’ve understood and acknowledged the possibility of self-fulfilling banking crises, you become aware that similar things can happen elsewhere.

Perhaps the most notable case in relatively recent times was the euro crisis of 2010-12. Market confidence in the economies of southern Europe collapsed, leading to huge spreads between the interest rates on, for example, Portuguese bonds and those on German bonds. The conventional wisdom at the time — especially in Germany — was that countries were being justifiably punished for taking on excessive debt

the Belgian economist Paul De Grauwe argued that what was actually happening was a self-fulfilling panic — basically a run on the bonds of countries that couldn’t provide a backstop because they no longer had their own currencies.

Sure enough, when Mario Draghi, the president of the European Central Bank at the time, finally did provide a backstop in 2012 — he said the magic words “whatever it takes,” implying that the bank would lend money to the troubled governments if necessary — the spreads collapsed and the crisis came to an end:

It was followed by TikTok, the Chinese-owned video site, which uses machine-learning models to predict engagement and make recommendations to users.

“We see a difference for each platform because each platform has different mechanisms for virality on it,” said Jeff Allen, a former integrity officer at Facebook and a founder and the chief research officer at the Integrity Institute. “The more mechanisms there are for virality on the platform, the more we see misinformation getting additional distribution.”

The institute calculated its findings by comparing posts that members of the International Fact-Checking Network have identified as false with the engagement of previous posts that were not flagged from the same accounts

Facebook, according to the sample that the institute has studied so far, had the most instances of misinformation but amplified such claims to a lesser degree, in part because sharing posts requires more steps. But some of its newer features are more prone to amplify misinformation, the institute found

Facebook’s amplification factor of video content alone is closer to TikTok’s, the institute found. That’s because the platform’s Reels and Facebook Watch, which are video features, “both rely heavily on algorithmic content recommendations” based on engagements, according to the institute’s calculations.

Instagram, which like Facebook is owned by Meta, had the lowest amplification rate. There was not yet sufficient data to make a statistically significant estimate for YouTube, according to the institute.

we’re networked organisms who move around in shifting surroundings, environments that have the power to transform our thinking

Annie Murphy Paul’s new book, “The Extended Mind,” which exhorts us to use our entire bodies, our surroundings and our relationships to “think outside the brain.”

In 2011, she published “Origins,” which focused on all the ways we are shaped by the environment, before birth and minute to minute thereafter.

“In the nature-nurture dynamic, nurture begins at the time of conception. The food the mother eats, the air she breathes, the water she drinks, the stress or trauma she experiences — all may affect her child for better or worse, over the decades to come.”

a down-to-earth take on the science of epigenetics — how environmental signals become catalysts for gene expression

the parallel to this latest book is that the boundaries we commonly assume to be fixed are actually squishy. The moment of a child’s birth, her I.Q. scores or fMRI snapshots of what’s going on inside her brain — all are encroached upon and influenced by outside forces.

awareness of our internal signals, such as exactly when our hearts beat, or how cold and clammy our hands are, can boost our performance at the poker table or in the financial markets, and even improve our pillow talk

“Though we typically think of the brain as telling the body what to do, just as much does the body guide the brain with an array of subtle nudges and prods. One psychologist has called this guide our ‘somatic rudder,’

The “body scan” aspect of mindfulness meditation that has been deployed by the behavioral medicine pioneer Jon Kabat-Zinn may help people lower their heart rates and blood pressure,

techniques that help us pinpoint their signals can foster well-being

Tania Singer has shown how the neural circuitry underlying compassion is strengthened by meditation practice

our thoughts “are powerfully shaped by the way we move our bodies.” Gestures help us understand spatial concepts; indeed, “without gesture as an aid, students may fail to understand spatial ideas at all,”

looking out on grassy expanses near loose clumps of trees and a source of water helps us solve problems. “Passive attention,” she writes, is “effortless: diffuse and unfocused, it floats from object to object, topic to topic. This is the kind of attention evoked by nature, with its murmuring sounds and fluid motions; psychologists working in the tradition of James call this state of mind ‘soft fascination.’”

The chapters on the ways natural and built spaces reflect universal preferences and enhance the thinking process felt like a respite

But one piece of advice almost no one is giving? Be lucky. Pediatrician Neil Stone says that there’s no “secret” for staying Covid-19 free because there’s just too much luck involved.

As for me, I have some data that can, to an extent, quantify and explain my own good luck in avoiding Covid so far. I’m participating in a study on immunity which allowed me to learn that my blood still carries loads of antibodies induced by my vaccine and December booster shot, and no signs of any prior infection. Not everyone’s antibodies wane at the same rate, and in some people, the antibodies don’t wane much at all. (At some point it should become routine to collect this information to help people decide whether to get additional booster shots.)

My high level of vaccine antibodies probably explains my success more than my behavior. I make some effort to avoid Covid, but have been far from perfect. And I’ve been potentially exposed at least twice: Once last December, when someone at a small holiday gathering I’d attended developed symptoms the next day, and more recently, when I shared a large indoor space with two people who later tested positive. But according to my lab work, I’ve never had even a silent infection.

It’s possible I was protected by my high antibodies, or that some quirk of air flow meant I never breathed in enough virus to get sick. Or perhaps I benefited from a different form of luck. There’s another facet to immunity called the innate immune system, which acts as a first line of defense and sometimes knocks out a virus or other pathogen before it replicates enough to elicit the production of antibodies. Good innate immunity might help explain something many of us have experienced — not getting a cold or flu even when sleeping in the same bed with the sick person through the whole illness.

Stress, diet, general health and even sunlight might all affect innate immunity. So could other factors. There’s so much we still don’t know about the immune system. And that’s one reason we talk about “luck.”

understanding how the luck works could help other people avoid Covid, whether for the first time or for the second or third time. Taking a closer look at what passed for luck helped researchers like Gary Taubes discover that public health had obesity all wrong, and the standard high carb/low fat diets were causing people to gain weight.

Essentially, Lasch was attacking the notion, fashionable as Americans basked in their seeming victory over the Soviet Union in the Cold War, that history had a direction — and that one would be wise to stay on the “right side” of it.

Francis Fukuyama expressed a version of this triumphalist idea in his famous 1992 book, “The End of History and the Last Man,” in which he celebrated the notion that History with a capital “H,” in the sense of a battle between competing ideas, was ending with communism left to smolder on Ronald Reagan’s famous ash heap.

One of Martin Luther King Jr.’s most frequently quoted lines speaks to a similar thought, albeit in a different context: “T​he arc of the moral universe is long, but it bends toward justice.” Though he had read Lasch, Obama quoted that line often, just as he liked to say that so-and-so would be “on the wrong side of history” if they didn’t live up to his ideals — whether the issue was same-sex marriage, health policy or the Russian occupation of Crimea.

The memo goes on to list two sets of words: “Optimistic Positive Governing Words” and “Contrasting Words,” which carried negative connotations. One of the latter group was the word “liberal,” sandwiched between “intolerant” and “lie.”

So what’s the difference between a progressive and a liberal?To vastly oversimplify matters, liberal usually refers to someone on the center-left on a two-dimensional political spectrum, while progressive refers to someone further left.

But “liberal” has taken a beating in recent decades — from both left and right.

In the late 1980s and 1990s, Republicans successfully demonized the word “liberal,” to the point where many Democrats shied away from it in favor of labels like “conservative Democrat” or, more recently, “progressive.”

“Is the story of the 20th century about the defeat of the Soviet Union, or was it about two world wars and a Holocaust?” asked Matthew Sitman, the co-host of the “Know Your Enemy” podcast, which recently hosted a discussion on Lasch and the fascination many conservatives have with his ideas. “It really depends on how you look at it.”

None of this was an accident. In 1996, Representative Newt Gingrich of Georgia circulated a now-famous memo called “Language: A Key Mechanism of Control.”

The authors urged their readers: “The words and phrases are powerful. Read them. Memorize as many as possible.”

Republicans subsequently had a great deal of success in associating the term “liberal” with other words and phrases voters found uncongenial: wasteful spending, high rates of taxation and libertinism that repelled socially conservative voters.

Many on the left began identifying themselves as “progressive” — which had the added benefit of harking back to movements of the late 19th and early 20th centuries that fought against corruption, opposed corporate monopolies, pushed for good-government reforms and food safety and labor laws and established women’s right to vote.

Allies of Bill Clinton founded the Progressive Policy Institute, a think tank associated with so-called Blue Dog Democrats from the South.

Now, scrambling the terminology, groups like the Progressive Change Campaign Committee agitate on behalf of proudly left-wing candidates

In 2014, Charles Murray, the polarizing conservative scholar, urged readers of The Wall Street Journal’s staunchly right-wing editorial section to “start using ‘liberal’ to designate the good guys on the left, reserving ‘progressive’ for those who are enthusiastic about an unrestrained regulatory state.”

As Sanders and acolytes like Representative Alexandria Ocasio-Cortez of New York have gained prominence over the last few election cycles, many on the left-wing end of the spectrum have begun proudly applying other labels to themselves, such as “democratic socialist.”

To little avail so far, Kazin, the Georgetown historian, has been urging them to call themselves “social democrats” instead — as many mainstream parties do in Europe.“It’s not a good way to win elections in this country, to call yourself a socialist,” he said.
