Parents need to know that when children go online, they are entering a world of influencers, many of whom are hoping to make money by pushing dangerous products. It’s a world that’s invisible to us

when we log on to our social media, we don’t see what they see. Thanks to algorithms and ad targeting, I see videos about the best lawn fertilizer and wrinkle laser masks, while Ian is being fed reviews of flavored vape pens and beautiful women livestreaming themselves gambling crypto and urging him to gamble, too.

Smartphones are taking our kids to a different world

Greyson Imm, an 18-year-old high school student in Prairie Village, Kan., said he was 17 when Zyn videos started appearing on his TikTok feed. The videos multiplied through the spring, when they were appearing almost daily. “Nobody had heard about Zyn until very early 2023,” he said. Now, a “lot of high schoolers have been using Zyn. It’s really taken off, at least in our community.”

all of this is, unfortunately, only part of what makes social media dangerous.

The tobacco conglomerate Philip Morris International acquired the Zyn maker Swedish Match in 2022 as part of a strategic push into smokeless products, a category it projects could help drive an expected $2 billion in U.S. revenue in 2024.

P.M.I. is also a company that has long denied it markets tobacco products to minors despite decades of research accusing it of just that. One 2022 study alone found its brands advertising near schools and playgrounds around the globe.

the ’90s, when magazines ran full-page Absolut Vodka ads in different colors, which my friends and I collected and taped up on our walls next to pictures of a young Leonardo DiCaprio — until our parents tore them down. This was advertising that appealed to me as a teenager but was also visible to my parents, and — crucially — to regulators, who could point to billboards near schools or flavored vodka ads in fashion magazines and say, this is wrong.

Even the most committed parent today doesn’t have the same visibility into what her children are seeing online, so it is worth explaining how products like Zyn end up in social feeds

influencers. They aren’t traditional pitch people. Think of them more like the coolest kids on the block. They establish a following thanks to their personality, experience or expertise. They share how they’re feeling, they share what they’re thinking about, they share stuff they l

With ruthless efficiency, social media can deliver unlimited amounts of the content that influencers create or inspire. That makes the combination of influencers and social-media algorithms perhaps the most powerful form of advertising ever invented.

Videos like his operate like a meme: It’s unintelligible to the uninitiated, it’s a hilarious inside joke to those who know, and it encourages the audience to spread the message

Enter Tucker Carlson. Mr. Carlson, the former Fox News megastar who recently started his own subscription streaming service, has become a big Zyn influencer. He’s mentioned his love of Zyn in enough podcasts and interviews to earn the nickname Tucker CarlZyn.

was Max VanderAarde. You can glimpse him in a video from the event wearing a Santa hat and toasting Mr. Carlson as they each pop Zyns in their mouths. “You can call me king of Zynbabwe, or Tucker CarlZyn’s cousin,” he says in a recent TikTok. “Probably, what, moved 30 mil cans last year?”

Freezer Tarps, Mr. VanderAarde’s TikTok account, appears to have been removed after I asked the company about it. Left up are the large number of TikToks by the likes of @lifeofaZyn, @Zynfluencer1 and @Zyntakeover; those hashtagged to #Zynbabwe, one of Freezer Tarps’s favorite terms, have amassed more than 67 million views. So it’s worth breaking down Mr. VanderAarde’s videos.

All of these videos would just be jokes (in poor taste) if they were seen by adults only. They aren’t. But we can’t know for sure how many children follow the Nelk Boys or Freezer Tarps — social-media companies generally don’t release granular age-related data to the public. Mr. VanderAarde, who responded to a few of my questions via LinkedIn, said that nearly 95 percent of his followers are over the age of 18.

They’re incentivized to increase their following and, in turn, often their bank accounts. Young people are particularly susceptible to this kind of promotion because their relationship with influencers is akin to the intimacy of a close friend.

The helicopter video has already been viewed more than one million times on YouTube, and iterations of it have circulated widely on TikTok.

YouTube said it eventually determined that four versions of the Carlson Zyn videos were not appropriate for viewers under age 18 under its community guidelines and restricted access to them by age

Mr. Carlson declined to comment on the record beyond his two-word statement. The Nelk Boys didn’t respond to requests for comment. Meta declined to comment on the record. TikTok said it does not allow content that promotes tobacco or its alternatives. The company said that it has over 40,000 trust and safety experts who work to keep the platform safe and that it prevented teenagers’ accounts from viewing over two million videos globally that show the consumption of tobacco products by adults. TikTok added that in the third quarter of 2023 it proactively removed 97 percent of videos that violated its alcohol, tobacco and drugs policy.

Greyson Imm, the high school student in Prairie Village, Kan., points to Mr. VanderAarde as having brought Zyn “more into the mainstream.” Mr. Imm believes his interest in independent comedy on TikTok perhaps made him a target for Mr. VanderAarde’s videos. “He would create all these funny phrases or things that would make it funny and joke about it and make it relevant to us.”

It wasn’t long before Mr. Imm noticed Zyn blowing up among his classmates — so much so that the student, now a senior at Shawnee Mission East High School, decided to write a piece in his school newspaper about it. He conducted an Instagram poll from the newspaper’s account and found that 23 percent of the students who responded used oral nicotine pouches during school.

“Upper-decky lip cushions, ferda!” Mr. VanderAarde coos in what was one of his popular TikTok videos, which had been liked more than 40,000 times. The singsong audio sounds like gibberish to most people, but it’s actually a call to action. “Lip cushion” is a nickname for a nicotine pouch, and “ferda” is slang for “the guys.”

“I have fun posting silly content that makes fun of pop culture,” Mr. VanderAarde said to me in our LinkedIn exchange.

I turned to Influencity, a software program that estimates the ages of social media users by analyzing profile photos and selfies in recent posts. Influencity estimated that roughly 10 percent of the Nelk Boys’ followers on YouTube are ages 13 to 17. That’s more than 800,000 children.

I’ve spent the past three years studying media manipulation and memes, and what I see in Freezer Tarps’s silly content is strategy. The use of Zyn slang seems like a way to turn interest in Zyn into a meme that can be monetized through merchandise and other business opportunities.

Such as? Freezer Tarps sells his own pouch product, Upperdeckys, which delivers caffeine instead of nicotine and is available in flavors including cotton candy and orange creamsicle. In addition to jockeying for sponsorship, Mr. Carlson may also be trying to establish himself with a younger, more male, more online audience as his new media company begins building its subscriber base

This is the kind of viral word-of-mouth marketing that looks like entertainment, functions like culture and can increase sales

What’s particularly galling about all of this is that we as a society already agreed that peddling nicotine to kids is not OK. It is illegal to sell nicotine products to anyone under the age of 21 in all 50 states

numerous studies have shown that the younger people are when they try nicotine for the first time, the more likely they will become addicted to it. Nearly 90 percent of adults who smoke daily started smoking before they turned 18.

Decades later — even after Juul showed the power of influencers to help addict yet another generation of children — the courts, tech companies and regulators still haven’t adequately grappled with the complexities of the influencer economy.

Facebook, Instagram and TikTok all have guidelines that prohibit tobacco ads and sponsored, endorsed or partnership-based content that promotes tobacco products. Holding them accountable for maintaining those standards is a bigger question.

We need a new definition of advertising that takes into account how the internet actually works. I’d go so far as to propose that the courts broaden the definition of advertising to include all influencer promotion. For a product as dangerous as nicotine, I’d put the bar to be considered an influencer as low as 1,000 followers on a social-media account, and maybe if a video from someone with less of a following goes viral under certain legal definitions, it would become influencer promotion.

Laws should require tech companies to share data on what young people are seeing on social media and to prevent any content promoting age-gated products from reaching children’s feeds

hose efforts must go hand in hand with social media companies putting real teeth behind their efforts to verify the ages of their users. Government agencies should enforce the rules already on the books to protect children from exposure to addictive products,

I refuse to believe there aren’t ways to write laws and regulations that can address these difficult questions over tech company liability and free speech, that there aren’t ways to hold platforms more accountable for advertising that might endanger kids. Let’s stop treating the internet like a monster we can’t control. We built it. We foisted it upon our children. We had better try to protect them from its potential harms as best we can.

The answer to both lies in one word: satiety. It’s a concept that we don’t use much in everyday life but that we’ve all experienced at some point. It describes the sensation of having had enough and not wanting any more.

The primary reason we have gained weight at a pace unprecedented in human history is that our diets have radically changed in ways that have deeply undermined our ability to feel sated

The evidence is clear that the kind of food my father grew up eating quickly makes you feel full. But the kind of food I grew up eating, much of which is made in factories, often with artificial chemicals, left me feeling empty and as if I had a hole in my stomach

In a recent study of what American children eat, ultraprocessed food was found to make up 67 percent of their daily diet. This kind of food makes you want to eat more and more. Satiety comes late, if at all.

After he moved in 2000 to the United States in his 20s, he gained 30 pounds in two years. He began to wonder if the American diet has some kind of strange effect on our brains and our cravings, so he designed an experiment to test it.

He and his colleague Paul Johnson raised a group of rats in a cage and gave them an abundant supply of healthy, balanced rat chow made out of the kind of food rats had been eating for a very long time. The rats would eat it when they were hungry, and then they seemed to feel sated and stopped. They did not become fat.

then Dr. Kenny and his colleague exposed the rats to an American diet: fried bacon, Snickers bars, cheesecake and other treats. They went crazy for it. The rats would hurl themselves into the cheesecake, gorge themselves and emerge with their faces and whiskers totally slicked with it. They quickly lost almost all interest in the healthy food, and the restraint they used to show around healthy food disappeared. Within six weeks, their obesity rates soared.

They took all the processed food away and gave the rats their old healthy diet. Dr. Kenny was confident that they would eat more of it, proving that processed food had expanded their appetites. But something stranger happened. It was as though the rats no longer recognized healthy food as food at all, and they barely ate it. Only when they were starving did they reluctantly start to consume it again.

Drugs like Ozempic work precisely by making us feel full.

processed and ultraprocessed food create a raging hole of hunger, and these treatments can repair that hole

the drugs are “an artificial solution to an artificial problem.”

Yet we have reacted to this crisis largely caused by the food industry as if it were caused only by individual moral dereliction

Why do we turn our anger inward and not outward at the main cause of the crisis? And by extension, why do we seek to shame people taking Ozempic but not those who, say, take drugs to lower their blood pressure?

The first is the belief that obesity is a sin.

The second idea is that we are all in a competition when it comes to weight. Ours is a society full of people fighting against the forces in our food that are making us fatter.

Looked at in this way, people on Ozempic can resemble cyclists like Lance Armstrong who used performance-enhancing drugs.

We can’t find our way to a sane, nontoxic conversation about obesity or Ozempic until we bring these rarely spoken thoughts into the open and reckon with them

remember the competition isn’t between you and your neighbor who’s on weight-loss drugs. It’s between you and a food industry constantly designing new ways to undermine your satiety.

Reducing or reversing obesity hugely boosts health, on average: We know from years of studying bariatric surgery that it slashes the risks of cancer, heart disease and diabetes-related death. Early indications are that the new anti-obesity drugs are moving people in a similar radically healthier direction,

But these drugs may increase the risk for thyroid cancer.

Do we want these weight loss drugs to be another opportunity to tear one another down? Or do we want to realize that the food industry has profoundly altered the appetites of us all — leaving us trapped in the same cage, scrambling to find a way out?

The ordinary fixes—the kind that draw on people’s will, and require eating less and moving more—rarely have a large or lasting effect. Indeed, America itself has suffered through a long, maddening history of failed attempts to change its habits on a national scale: a yo-yo diet of well-intentioned treatments, policies, and other social interventions that only ever lead us back to where we started

Through it all, obesity rates keep going up; the diabetes epidemic keeps worsening.

The most recent miracle, for Barb as well as for the nation, has come in the form of injectable drugs. In early 2021, the Danish pharmaceutical company Novo Nordisk published a clinical trial showing remarkable results for semaglutide, now sold under the trade names Wegovy and Ozempic.

Patients in the study who’d had injections of the drug lost, on average, close to 15 percent of their body weight—more than had ever been achieved with any other drug in a study of that size. Wadden knew immediately that this would be “an incredible revolution in the treatment of obesity.”

Many more drugs are now racing through development: survodutide, pemvidutide, retatrutide. (Among specialists, that last one has produced the most excitement: An early trial found an average weight loss of 24 percent in one group of participants.

In the United States, an estimated 189 million adults are classified as having obesity or being overweight

The drugs don’t work for everyone. Their major side effects—nausea, vomiting, and diarrhea—can be too intense for many patients. Others don’t end up losing any weight

For the time being, just 25 percent of private insurers offer the relevant coverage, and the cost of treatment—about $1,000 a month—has been prohibitive for many Americans.

The drugs have already been approved not just for people with diabetes or obesity, but for anyone who has a BMI of more than 27 and an associated health condition, such as high blood pressure or cholesterol. By those criteria, more than 140 million American adults already qualify

if this story goes the way it’s gone for other “risk factor” drugs such as statins and antihypertensives, then the threshold for prescriptions will be lowered over time, inching further toward the weight range we now describe as “normal.”

How you view that prospect will depend on your attitudes about obesity, and your tolerance for risk

The first GLP-1 drug to receive FDA approval, exenatide, has been used as a diabetes treatment for more than 20 years. No long-term harms have been identified—but then again, that drug’s long-term effects have been studied carefully only across a span of seven years

the data so far look very good. “These are now being used, literally, in hundreds of thousands of people across the world,” she told me, and although some studies have suggested that GLP-1 drugs may cause inflammation of the pancreas, or even tumor growth, these concerns have not borne out.

adolescents are injecting newer versions of these drugs, and may continue to do so every week for 50 years or more. What might happen over all that time?

“All of us, in the back of our minds, always wonder, Will something show up?  ” Although no serious problems have yet emerged, she said, “you wonder, and you worry.”

in light of what we’ve been through, it’s hard to see what other choices still remain. For 40 years, we’ve tried to curb the spread of obesity and its related ailments, and for 40 years, we’ve failed. We don’t know how to fix the problem. We don’t even understand what’s really causing it. Now, again, we have a new approach. This time around, the fix had better work.

The fen-phen revolution arrived at a crucial turning point for Wadden’s field, and indeed for his career. By then he’d spent almost 15 years at the leading edge of research into dietary interventions, seeing how much weight a person might lose through careful cutting of their calories.

But that sort of diet science—and the diet culture that it helped support—had lately come into a state of ruin. Americans were fatter than they’d ever been, and they were giving up on losing weight. According to one industry group, the total number of dieters in the country declined by more than 25 percent from 1986 to 1991.

Rejecting diet culture became something of a feminist cause. “A growing number of women are joining in an anti-diet movement,” The New York Times reported in 1992. “They are forming support groups and ceasing to diet with a resolve similar to that of secretaries who 20 years ago stopped getting coffee for their bosses.

Now Wadden and other obesity researchers were reaching a consensus that behavioral interventions might produce in the very best scenario an average lasting weight loss of just 5 to 10 percent

National surveys completed in 1994 showed that the adult obesity rate had surged by more than half since 1980, while the proportion of children classified as overweight had doubled. The need for weight control in America had never seemed so great, even as the chances of achieving it were never perceived to be so small.

Wadden wasn’t terribly concerned, because no one in his study had reported any heart symptoms. But ultrasounds revealed that nearly one-third of them had some degree of leakage in their heart valves. His “cure for obesity” was in fact a source of harm.

In December 1994, the Times ran an editorial on what was understood to be a pivotal discovery: A genetic basis for obesity had finally been found. Researchers at Rockefeller University were investigating a molecule, later named leptin, that gets secreted from fat cells and travels to the brain, and that causes feelings of satiety. Lab mice with mutations in the leptin gene—importantly, a gene also found in humans—overeat until they’re three times the size of other mice. “The finding holds out the dazzling hope,”

In April 1996, the doctors recommended yes: Dexfenfluramine was approved—and became an instant blockbuster. Patients received prescriptions by the hundreds of thousands every month. Sketchy wellness clinics—call toll-free, 1-888-4FEN-FEN—helped meet demand. Then, as now, experts voiced concerns about access. Then, as now, they worried that people who didn’t really need the drugs were lining up to take them. By the end of the year, sales of “fen” alone had surpassed $300 million.

It was nothing less than an awakening, for doctors and their patients alike. Now a patient could be treated for excess weight in the same way they might be treated for diabetes or hypertension—with a drug they’d have to take for the rest of their life.

the article heralded a “new understanding of obesity as a chronic disease rather than a failure of willpower.”

News had just come out that, at the Mayo Clinic in Minnesota, two dozen women taking fen-phen—including six who were, like Barb, in their 30s—had developed cardiac conditions. A few had needed surgery, and on the operating table, doctors discovered that their heart valves were covered with a waxy plaque.

Americans had been prescribed regular fenfluramine since 1973, and the newer drug, dexfenfluramine, had been available in France since 1985. Experts took comfort in this history. Using language that is familiar from today’s assurances regarding semaglutide and other GLP-1 drugs, they pointed out that millions were already on the medication. “It is highly unlikely that there is anything significant in toxicity to the drug that hasn’t been picked up with this kind of experience,” an FDA official named James Bilstad would later say in a Time cover story headlined “The Hot New Diet Pill.

“I know I can’t get any more,” she told Williams. “I have to use up what I have. And then I don’t know what I’m going to do after that. That’s the problem—and that is what scares me to death.” Telling people to lose weight the “natural way,” she told another guest, who was suggesting that people with obesity need only go on low-carb diets, is like “asking a person with a thyroid condition to just stop their medication.”

She’d gone off the fen-phen and had rapidly regained weight. “The voices returned and came back in a furor I’d never heard before,” Barb later wrote on her blog. “It was as if they were so angry at being silenced for so long, they were going to tell me 19 months’ worth of what they wanted me to hear. I was forced to listen. And I ate. And I ate. And ate.”

For Barb, rapid weight loss has brought on a different metaphysical confusion. When she looks in the mirror, she sometimes sees her shape as it was two years ago. In certain corners of the internet, this is known as “phantom fat syndrome,” but Barb dislikes that term. She thinks it should be called “body integration syndrome,” stemming from a disconnect between your “larger-body memory” and “smaller-body reality.

In 2003, the U.S. surgeon general declared obesity “the terror within, a threat that is every bit as real to America as the weapons of mass destruction”; a few months later, Eric Finkelstein, an economist who studies the social costs of obesity, put out an influential paper finding that excess weight was associated with up to $79 billion in health-care spending in 1998, of which roughly half was paid by Medicare and Medicaid. (Later he’d conclude that the number had nearly doubled in a decade.

In 2004, Finkelstein attended an Action on Obesity summit hosted by the Mayo Clinic, at which numerous social interventions were proposed, including calorie labeling in workplace cafeterias and mandatory gym class for children of all grades.

he message at their core, that soda was a form of poison like tobacco, spread. In San Francisco and New York, public-service campaigns showed images of soda bottles pouring out a stream of glistening, blood-streaked fat. Michelle Obama led an effort to depict water—plain old water—as something “cool” to drink.

Soon, the federal government took up many of the ideas that Brownell had helped popularize. Barack Obama had promised while campaigning for president that if America’s obesity trends could be reversed, the Medicare system alone would save “a trillion dollars.” By fighting fat, he implied, his ambitious plan for health-care reform would pay for itself. Once he was in office, his administration pulled every policy lever it could.

Michelle Obama helped guide these efforts, working with marketing experts to develop ways of nudging kids toward better diets and pledging to eliminate “food deserts,” or neighborhoods that lacked convenient access to healthy, affordable food. She was relentless in her public messaging; she planted an organic garden at the White House and promoted her signature “Let’s Move!” campaign around the country.

An all-out war on soda would come to stand in for these broad efforts. Nutrition studies found that half of all Americans were drinking sugar-sweetened beverages every day, and that consumption of these accounted for one-third of the added sugar in adults’ diets. Studies turned up links between people’s soft-drink consumption and their risks for type 2 diabetes and obesity. A new strand of research hinted that “liquid calories” in particular were dangerous to health.

when their field lost faith in low-calorie diets as a source of lasting weight loss, the two friends went in opposite directions. Wadden looked for ways to fix a person’s chemistry, so he turned to pharmaceuticals. Brownell had come to see obesity as a product of our toxic food environment: He meant to fix the world to which a person’s chemistry responded, so he started getting into policy.

The social engineering worked. Slowly but surely, Americans’ lamented lifestyle began to shift. From 2001 to 2018, added-sugar intake dropped by about one-fifth among children, teens, and young adults. From the late 1970s through the early 2000s, the obesity rate among American children had roughly tripled; then, suddenly, it flattened out.

although the obesity rate among adults was still increasing, its climb seemed slower than before. Americans’ long-standing tendency to eat ever-bigger portions also seemed to be abating.

sugary drinks—liquid candy, pretty much—were always going to be a soft target for the nanny state. Fixing the food environment in deeper ways proved much harder. “The tobacco playbook pretty much only works for soda, because that’s the closest analogy we have as a food item,

that tobacco playbook doesn’t work to increase consumption of fruits and vegetables, he said. It doesn’t work to increase consumption of beans. It doesn’t work to make people eat more nuts or seeds or extra-virgin olive oil.

Careful research in the past decade has shown that many of the Obama-era social fixes did little to alter behavior or improve our health. Putting calorie labels on menus seemed to prompt at most a small decline in the amount of food people ate. Employer-based wellness programs (which are still offered by 80 percent of large companies) were shown to have zero tangible effects. Health-care spending, in general, kept going up.

From the mid-1990s to the mid-2000s, the proportion of adults who said they’d experienced discrimination on account of their height or weight increased by two-thirds, going up to 12 percent. Puhl and others started citing evidence that this form of discrimination wasn’t merely a source of psychic harm, but also of obesity itself. Studies found that the experience of weight discrimination is associated with overeating, and with the risk of weight gain over time.

obesity rates resumed their ascent. Today, 20 percent of American children have obesity. For all the policy nudges and the sensible revisions to nutrition standards, food companies remain as unfettered as they were in the 1990s, Kelly Brownell told me. “Is there anything the industry can’t do now that it was doing then?” he asked. “The answer really is no. And so we have a very predictable set of outcomes.”

she started to rebound. The openings into her gastric pouch—the section of her stomach that wasn’t bypassed—stretched back to something like their former size. And Barb found ways to “eat around” the surgery, as doctors say, by taking food throughout the day in smaller portions

Bariatric surgeries can be highly effective for some people and nearly useless for others. Long-term studies have found that 30 percent of those who receive the same procedure Barb did regain at least one-quarter of what they lost within two years of reaching their weight nadir; more than half regain that much within five years.

if the effects of Barb’s surgery were quickly wearing off, its side effects were not: She now had iron, calcium, and B12 deficiencies resulting from the changes to her gut. She looked into getting a revision of the surgery—a redo, more or less—but insurance wouldn’t cover it

She found that every health concern she brought to doctors might be taken as a referendum, in some way, on her body size. “If I stubbed my toe or whatever, they’d just say ‘Lose weight.’ ” She began to notice all the times she’d be in a waiting room and find that every chair had arms. She realized that if she was having a surgical procedure, she’d need to buy herself a plus-size gown—or else submit to being covered with a bedsheet when the nurses realized that nothing else would fit.

Barb grew angrier and more direct about her needs—You’ll have to find me a different chair, she started saying to receptionists. Many others shared her rage. Activists had long decried the cruel treatment of people with obesity: The National Association to Advance Fat Acceptance had existed, for example, in one form or another, since 1969; the Council on Size & Weight Discrimination had been incorporated in 1991. But in the early 2000s, the ideas behind this movement began to wend their way deeper into academia, and they soon gained some purchase with the public.

“Our public-health efforts to address obesity have failed,” Eric Finkelstein, the economist, told me.

Others attacked the very premise of a “healthy weight”: People do not have any fundamental need, they argued, morally or medically, to strive for smaller bodies as an end in itself. They called for resistance to the ideology of anti-fatness, with its profit-making arms in health care and consumer goods. The Association for Size Diversity and Health formed in 2003; a year later, dozens of scholars working on weight-related topics joined together to create the academic field of fat studies.

As the size-diversity movement grew, its values were taken up—or co-opted—by Big Business. Dove had recently launched its “Campaign for Real Beauty,” which included plus-size women. (Ad Age later named it the best ad campaign of the 21st century.) People started talking about “fat shaming” as something to avoid

By 2001, Bacon, who uses they/them pronouns, had received their Ph.D. and finished a rough draft of a book, Health at Every Size, which drew inspiration from a broader movement by that name among health-care practitioners

But something shifted in the ensuing years. In 2007, Bacon got a different response, and the book was published. Health at Every Size became a point of entry for a generation of young activists and, for a time, helped shape Americans’ understanding of obesity.

Some experts were rethinking their advice on food and diet. At UC Davis, a physiologist named Lindo Bacon who had struggled to overcome an eating disorder had been studying the effects of “intuitive eating,” which aims to promote healthy, sustainable behavior without fixating on what you weigh or how you look

The heightened sensitivity started showing up in survey data, too. In 2010, fewer than half of U.S. adults expressed support for giving people with obesity the same legal protections from discrimination offered to people with disabilities. In 2015, that rate had risen to three-quarters.

In Bacon’s view, the 2000s and 2010s were glory years. “People came together and they realized that they’re not alone, and they can start to be critical of the ideas that they’ve been taught,” Bacon told me. “We were on this marvelous path of gaining more credibility for the whole Health at Every Size movement, and more awareness.”

that sense of unity proved short-lived; the movement soon began to splinter. Black women have the highest rates of obesity, and disproportionately high rates of associated health conditions. Yet according to Fatima Cody Stanford, an obesity-medicine physician at Harvard Medical School, Black patients with obesity get lower-quality care than white patients with obesity.

That system was exactly what Bacon and the Health at Every Size movement had set out to reform. The problem, as they saw it, was not so much that Black people lacked access to obesity medicine, but that, as Bacon and the Black sociologist Sabrina Strings argued in a 2020 article, Black women have been “specifically targeted” for weight loss, which Bacon and Strings saw as a form of racism

But members of the fat-acceptance movement pointed out that their own most visible leaders, including Bacon, were overwhelmingly white. “White female dietitians have helped steal and monetize the body positive movement,” Marquisele Mercedes, a Black activist and public-health Ph.D. student, wrote in September 2020. “And I’m sick of it.”

Tensions over who had the standing to speak, and on which topics, boiled over. In 2022, following allegations that Bacon had been exploitative and condescending toward Black colleagues, the Association for Size Diversity and Health expelled them from its ranks and barred them from attending its events.

As the movement succumbed to in-fighting, its momentum with the public stalled. If attitudes about fatness among the general public had changed during the 2000s and 2010s, it was only to a point. The idea that some people can indeed be “fit but fat,” though backed up by research, has always been a tough sell.

Although Americans had become less inclined to say they valued thinness, measures of their implicit attitudes seemed fairly stable. Outside of a few cities such as San Francisco and Madison, Wisconsin, new body-size-discrimination laws were never passed.

In the meantime, thinness was coming back into fashion

In the spring of 2022, Kim Kardashian—whose “curvy” physique has been a media and popular obsession—boasted about crash-dieting in advance of the Met Gala. A year later, the model and influencer Felicity Hayward warned Vogue Business that “plus-size representation has gone backwards.” In March of this year, the singer Lizzo, whose body pride has long been central to her public persona, told The New York Times that she’s been trying to lose weight. “I’m not going to lie and say I love my body every day,” she said.

Among the many other dramatic effects of the GLP-1 drugs, they may well have released a store of pent-up social pressure to lose weight.

If ever there was a time to debate that impulse, and to question its origins and effects, it would be now. But Puhl told me that no one can even agree on which words are inoffensive. The medical field still uses obesity, as a description of a diagnosable disease. But many activists despise that phrase—some spell it with an asterisk in place of the e—and propose instead to reclaim fat.

Everyone seems to agree on the most important, central fact: that we should be doing everything we can to limit weight stigma. But that hasn’t been enough to stop the arguing.

Things feel surreal these days to just about anyone who has spent years thinking about obesity. At 71, after more than four decades in the field, Thomas Wadden now works part-time, seeing patients just a few days a week. But the arrival of the GLP-1 drugs has kept him hanging on for a few more years, he said. “It’s too much of an exciting period to leave obesity research right now.”

When everyone is on semaglutide or tirzepatide, will the soft-drink companies—Brownell’s nemeses for so many years—feel as if a burden has been lifted? “My guess is the food industry is probably really happy to see these drugs come along,” he said. They’ll find a way to reach the people who are taking GLP‑1s, with foods and beverages in smaller portions, maybe. At the same time, the pressures to cut back on where and how they sell their products will abate.

the triumph in obesity treatment only highlights the abiding mystery of why Americans are still getting fatter, even now

Perhaps one can lay the blame on “ultraprocessed” foods, he said. Maybe it’s a related problem with our microbiomes. Or it could be that obesity, once it takes hold within a population, tends to reproduce itself through interactions between a mother and a fetus. Others have pointed to increasing screen time, how much sleep we get, which chemicals are in the products that we use, and which pills we happen to take for our many other maladies.

“The GLP-1s are just a perfect example of how poorly we understand obesity,” Mozaffarian told me. “Any explanation of why they cause weight loss is all post-hoc hand-waving now, because we have no idea. We have no idea why they really work and people are losing weight.”

The new drugs—and the “new understanding of obesity” that they have supposedly occasioned—could end up changing people’s attitudes toward body size. But in what ways

When the American Medical Association declared obesity a disease in 2013, Rebecca Puhl told me, some thought “it might reduce stigma, because it was putting more emphasis on the uncontrollable factors that contribute to obesity.” Others guessed that it would do the opposite, because no one likes to be “diseased.”

why wasn’t there another kind of nagging voice that wouldn’t stop—a sense of worry over what the future holds? And if she wasn’t worried for herself, then what about for Meghann or for Tristan, who are barely in their 40s? Wouldn’t they be on these drugs for another 40 years, or even longer? But Barb said she wasn’t worried—not at all. “The technology is so much better now.” If any problems come up, the scientists will find solutions.

With consumers buying so little, at least relative to the Chinese economy’s productive capacity, how can the nation generate enough demand to keep that capacity in use? The main answer, as Michael Pettis points out, has been to promote extremely high rates of investment, more than 40 percent of G.D.P. The trouble is that it’s hard to invest that much money without running into severely diminishing returns.

financial repression — paying low interest on savings and making cheap loans to favored borrowers — that holds down household income and diverts it to government-controlled investment, a weak social safety net that causes families to accumulate savings to deal with possible emergencies, and more.

Part of the answer is bad leadership. President Xi Jinping is starting to look like a poor economic manager, whose propensity for arbitrary interventions — which is something autocrats tend to do — has stifled private initiative.

But China’s working-age population peaked around 2010 and has been declining ever since. While China has shown impressive technological capacity in some areas, its overall productivity also appears to be stagnating.

very high rates of investment may be sustainable if, like China in the early 2000s, you have a rapidly growing work force and high productivity growth as you catch up with Western economies

This, in short, isn’t a nation that can productively invest 40 percent of G.D.P. Something has to give.

the government was able to mask the problem of inadequate consumer spending for a number of years by promoting a gigantic real estate bubble. In fact, China’s real estate sector became insanely large by international standards.

what China must do seems straightforward: end financial repression and allow more of the economy’s income to flow through to households, and strengthen the social safety net so that consumers don’t feel the need to hoard cash. And as it does this it can ramp down its unsustainable investment spending.

But there are powerful players, especially state-owned enterprises, that benefit from financial repression

And when it comes to strengthening the safety net, the leader of this supposedly communist regime sounds a bit like the governor of Mississippi, denouncing “welfarism” that creates “lazy people.”

Japan ended up managing its downshifting well. It avoided mass unemployment, it never lost social and political cohesion, and real G.D.P. per working-age adult actually rose 50 percent over the next three decades, not far short of growth in the United States.

My great concern is that China may not respond nearly as well. How cohesive will China be in the face of economic trouble? Will it try to prop up its economy with an export surge that will run headlong into Western efforts to promote green technologies? Scariest of all, will it try to distract from domestic difficulties by engaging in military adventurism?

In my talks with more than 100 voters, no one mentioned the word “authoritarian.” But that was no surprise — many everyday people don’t think in those terms. Focusing solely on these labels can miss the point.

Authoritarian leaders project qualities that many voters — not just Trump voters — admire: strength, a sense of control, even an ends-justify-the-means leadership style

Our movie-hero presidents, Top Gun pilots and crusading lawyers often take matters into their own hands or break the rules in ways that we cheer.

they have something in common with Trump: They are seen as having special or singular strengths, an “I alone can fix it” power.

argued that it’s just Trump who’s strong and honest enough to say it out loud — for them, a sign that he’s honest.

also see him as an authentic strongman who is not a typical politician

during Trump’s presidency, “there weren’t any active wars going on except for Afghanistan, which he did not start. He started no new wars. Our economy was great. Our gas prices were under 2 bucks a gallon. It’s just common sense to me. If it ain’t broke, don’t fix it.”

Trump’s vulgar language, his penchant for insults (“Don’t call him a fat pig,” he said about Chris Christie) and his rhetoric about political opponents (promising to “root out the communists, Marxists, fascists and the radical left thugs that live like vermin within the confines of our country”) are seen as signs of authenticity and strength by his supporters

Jan. 6, 2021, at the Capitol. I didn’t encounter a single outright supporter of what happened, but many people explained the events away. Increasingly separate information environments and our fractured media ecology shape the way people view that day.

they think Biden is too weak and too old to be president. They talk about him with attack lines frequently used by Trump, saying that he’s senile, falling down stairs, losing his train of thought while talking and so on

What I heard from voters drawn to Trump was that he had a special strength in making the economy work better for them than Biden has, and that he was a tough, “don’t mess with me” absolutist, which they see as helping to prevent new wars.

Many Trump supporters told me that had Trump been president, the war in Ukraine wouldn’t have happened because he would have been strong enough to be feared by Vladimir Putin or smart enough to make a deal with him, if necessary

Neither would Hamas have dared attack Israel, a few added. Their proof was that during Trump’s presidency, these wars indeed did not happen.

Like many of these right-wing populists, Trump leans heavily on the message that he alone is strong enough to keep America peaceful and prosperous in a scary world

In Iowa, Trump praised Orban himself before telling a cheering crowd: “For four straight years, I kept America safe. I kept Israel safe. I kept Ukraine safe, and I kept the entire world safe.”

from Trump, these statements often resulted in the crowds leaping to their feet (actually, some rallygoers never sat down) and interrupting him with applause and cheering.

That’s charisma. Charisma is an underrated aspect of political success — and it’s not necessarily a function of political viewpoint. Bill Clinton and Barack Obama oozed it, for example, and so does Trump.

Charismatic leaders, Weber wrote, “have a certain quality of an individual personality, by virtue of which he is set apart from ordinary men,” and is sought as a leader, especially when people feel the times are troubled.

Polls also show that voters believe that Trump would do a better job than Biden on the economy, foreign policy and immigration. It was Trump’s perceived strength, in contrast with Biden’s perceived weakness, that was the common theme that tied it all together for his supporters.

“I’m not concerned with Jan. 6,” Finch said. “I don’t trust our government. I don’t trust anything they’re saying. They’ve been doing this to Black people for so long, railroading them, so they have zero credibility. So I don’t even care about it, and I don’t want to hear about Jan. 6.”

For her, biased mainstream media is misrepresenting him. “He was making the point that he’d use executive orders on Day 1, like the others do — executive orders bypass Congress, but that’s how it’s done these days,” she said. “He was being sarcastic, not saying he’d be a real dictator.”

What’s a bit of due process overstepped here, a trampled emoluments clause there, when all politicians are believed to be corrupt and fractured information sources pump very different messages about reality?

Politicians projecting strength at the expense of the rules of liberal democracy isn’t a new phenomenon in the United States, or the world. Thomas Jefferson worried about it. So did Plato. Perhaps acknowledging that Trump’s appeal isn’t that mysterious can help people grapple with its power.

Understanding how empathy can immobilize us like that is a critical step for helping others — and ourselves.

Empathic distress explains why many people have checked out in the wake of these tragedies

Having concluded that nothing they do will make a difference, they start to become indifferent.

The symptoms of empathic distress were originally diagnosed in health care, with nurses and doctors who appeared to become insensitive to the pain of their patients.

Early researchers labeled it compassion fatigue and described it as the cost of caring.

when two neuroscientists, Olga Klimecki and Tania Singer, reviewed the evidence, they discovered that “compassion fatigue” is a misnomer. Caring itself is not costly. What drains people is not merely witnessing others’ pain but feeling incapable of alleviating it.

In times of sustained anguish, empathy is a recipe for more distress, and in some cases even depression. What we need instead is compassion.

empathy and compassion aren’t the same. Empathy absorbs others’ emotions as your own: “I’m hurting for you.”

Compassion focuses your action on their emotions: “I see that you’re hurting, and I’m here for you.”

“Empathy is biased,” the psychologist Paul Bloom writes. It’s something we usually reserve for our own group, and in that sense, it can even be “a powerful force for war and atrocity.”

Dr. Singer and their colleagues trained people to empathize by trying to feel other people’s pain. When the participants saw someone suffering, it activated a neural network that would light up if they themselves were in pain. It hurt. And when people can’t help, they escape the pain by withdrawing.

To combat this, the Klimecki and Singer team taught their participants to respond with compassion rather than empathy — focusing not on sharing others’ pain but on noticing their feelings and offering comfort.

A different neural network lit up, one associated with affiliation and social connection. This is why a growing body of evidence suggests that compassion is healthier for you and kinder to others than empathy:

When you see others in pain, instead of causing you to get overloaded and retreat, compassion motivates you to reach out and help

The most basic form of compassion is not assuaging distress but acknowledging it.

in my research, I’ve found that being helpful has a secondary benefit: It’s an antidote to feeling helpless.

To figure out who needs your support after something terrible happens, the psychologist Susan Silk suggests picturing a dart board, with the people closest to the trauma in the bull’s-eye and those more peripherally affected in the outer rings.

Once you’ve figured out where you belong on the dart board, look for support from people outside your ring, and offer it to people closer to the center.

Even if people aren’t personally in the line of fire, attacks targeting members of a specific group can shatter a whole population’s sense of security.

If you notice that people in your life seem disengaged around an issue that matters to you, it’s worth considering whose pain they might be carrying.

Instead of demanding that they do more, it may be time to show them compassion — and help them find compassion for themselves, too.

Your small gesture of kindness won’t end the crisis in the Middle East, but it can help someone else. And that can give you the strength to help more.

I’ve seen arguments that it goes back to the 1978 Bakke decision, when the Supreme Court effectively greenlit affirmative action in the name of diversity.

the problem with Bakke isn’t that it allowed diversity to be a consideration in admissions decisions. It’s that university administrators turned an allowance into a requirement, so a kind of racial gerrymander now permeates nearly every aspect of academic life, from admissions decisions to faculty appointments to the racial makeup of contributors to essay collections

If affirmative action had been administered with a lighter hand — more nudge than mandate — it might have survived the court’s scrutiny last year. Instead, it became a pervasive regime that frequently got in the way of the universities’ higher goals, particularly the open exchange of ideas.

skin color was the first thing The Harvard Crimson noted in its story about her taking office, and her missteps and questions about her academic work gave ammunition to detractors who claimed she owed her position solely to her race.

This is the poisoned pool in which Harvard now swims. Whenever it elevates someone like Gay, there’s an assumption by admirers and detractors alike that she’s a political symbol whose performance represents more than who she is as a person

dehumanization is the price any institution pays when considerations of social engineering supplant those of individual achievement.

It may take a generation after the end of affirmative action before someone like Gay can have the opportunity to be judged on her own merits, irrespective of her color.

the damage that the social-justice model has done to higher education will take longer to repair. In 2015, 57 percent of Americans expressed high confidence in higher education, according to a Gallup survey. Last year, the number had fallen to 36 percent, and that was before the wave of antisemitic campus outbursts. At Harvard, early admission applications fell by 17 percent last fall.

Harvard also sets the tone for the rest of American higher ed — and for public attitudes toward it. One of the secrets of America’s postwar success wasn’t simply the caliber of U.S. universities. It was the respect they engendered among ordinary people who aspired to send their children to them.

That respect is now being eroded to the point of being erased. For good reason

People admire, and will strive for, excellence — both for its own sake and for the status it confers. But status without excellence is a rapidly wasting asset, especially when it comes with an exorbitant price. That’s the position of much of American academia today. Two hundred thousand dollars or more is a lot to pay for lessons in how to be an anti-racist.

the intellectual rot is pervasive and won’t stop spreading until universities return to the idea that their central purpose is to identify and nurture and liberate the best minds, not to engineer social utopias.

Firewalls around the engines, nitrogen pumps in fuel tanks that help prevent immediate burning, and fire-resistant materials on seats and flooring most likely helped to keep the rising flames at bay, said Sonya A. Brown, a senior lecturer in aerospace design at the University of New South Wales in Sydney, Australia.

“Really, the Japan Airlines crew in this case performed extremely well,” Dr. Brown said. The fact that passengers did not stop to retrieve carry-on luggage or otherwise slow down the exit was “really critical,” she added.

Tadayuki Tsutsumi, an official at Japan Airlines, said the most important component of crew performance during an emergency was “panic control” and determining which exit doors were safe to use.

Former flight attendants described the rigorous training and drills that crew members undergo to prepare for emergencies. “When training for evacuation procedures, we repeatedly used smoke/fire simulation to make sure we could be mentally ready when situations like those occurred in reality,” Yoko Chang, a former cabin attendant and an instructor of aspiring crew members, wrote in an Instagram message.

Ms. Chang, who did not work for JAL, added that airlines require cabin crew members to pass evacuation exams every six months.

But only a handful of cancers—of the breast, lung, colon and cervix—have screening tests recommended by the U.S. Preventive Services Task Force

Many companies are developing blood tests that can detect cancer signals before symptoms occur, and Grail’s is the most advanced. A study found it can identify more than 50 types of cancer 52% of the time and the 12 deadliest cancers in Stages I through III 68% of the time.

There’s a hitch. The test costs $949 and isn’t covered by Medicare or most private insurance.

The trouble is that this cancer is almost never caught early. There’s no routine screening for it, and symptoms don’t develop until it is advanced. Mr. Royse, 64, had no idea he was sick until he took a blood test called Galleri, produced by the Menlo Park, Calif., startup Grail. He had surgery and chemotherapy and is now cancer-free.

Mr. Royse visited Grail’s website, which referred him to a telemedicine provider who ordered a test. Another telemedicine doctor walked him through his results, which showed a cancer signal likely emanating from the pancreas, gallbladder, stomach or esophagus.

An MRI revealed a suspicious mass on his pancreas, which a biopsy confirmed was cancerous. Mr. Royse had three months of chemotherapy, surgery and another three months of chemotherapy, which ended last February. Because pancreatic cancer often recurs, he gets CT and MRI scans every three months. In addition, he has signed up for startup Natera’s Signatera customized blood test, which checks DNA specific to the patient’s cancer and can signal its return before signs are visible on the scans

Grail’s test likewise looks for DNA shed by cancer cells, which is tagged by molecules called methyl groups that are specific to a cancer’s origin. Grail uses genetic sequencing and machine learning to recognize links between DNA methyl groups and particular cancers

The test “is based on how much DNA is being shed by tumor,” Grail’s president, Josh Ofman, says. “Some tumors shed a lot of DNA. Some shed almost none.

ut slow-growing tumors typically aren’t shedding a lot of DNA.” That reduces the probability that Grail’s test will identify indolent cancers that pose no immediate danger.

Grail’s test has a roughly 0.5% false-positive rate, meaning 1 in 200 patients who don’t have cancer will get a positive signal

Its positive predictive value is 43%, so that of every 100 patients with a positive signal, 43 actually have cancer

the legislation’s price tag could reduce political support. According to one private company’s estimate, the test could cost the government $39 billion to $145 billion over a decade. Mr. Goldman counters that analysts usually overestimate the costs and underestimate the benefits of medical interventions.

Because Grail uses machine learning to detect DNA-methylation cancer linkages, the Grail test’s accuracy should improve as more tests and patient data are collected

regulators may balk at approving the test, and insurers at covering it, until it becomes cheaper and more reliable.

How would the FDA weigh the risk that a false positive on a test like Grail’s could require invasive follow-up testing against the dire but hard-to-quantify risk that a deadly cancer wouldn’t be caught until it’s much harder to treat? It’s unclear.

some experts urge the FDA to require large randomized controlled trials before approving blood cancer tests. “Multicancer screening would entail tremendous costs and potentially substantial harms,” H. Gilbert Welch and Tanujit Dey of Brigham and Women’s Hospital wrote

Dr. Welch and Mr. Dey also suggested that companies should be required to prove their tests reduce overall mortality, even though the FDA doesn’t require drugmakers to prove their products reduce deaths or extend life. Clinical trials for the mRNA Covid vaccines didn’t show they reduced deaths.

One alternative is to rely on real-world studies, which Grail is already doing. One study of patients 50 and older without signs of cancer showed that the test doubled the number of cancers detected.

One recurring problem he has seen: “Epidemiologists are always getting cancer wrong,” he says. “Epidemiologists a decade ago said U.S. overtreats cancers. Well, no, the EU undertreats cancer.”

A 2012 study that he co-authored found that the higher U.S. spending on cancer care relative to Europe between 1983 and 1999 resulted in significantly higher survival rates for American patients than for those in Europe

By his study’s calculation, U.S. spending on cancer treatments during that period resulted in $556 billion in net benefits owing to reduced mortality.

He expects Galleri and other multicancer early-detection tests to reduce deaths and produce public-health and economic benefits that exceed their monetary costs

Expanding access to multicancer early-detection tests could also help solve the chicken-and-egg problem of drug development. Because few patients are diagnosed at early stages of some cancers, it’s hard to develop treatments for them

the positive predictive value for some recommended cancer screenings is far lower. Fewer than 1 in 10 women with an abnormal finding on a mammogram are diagnosed with breast cancer.

Mr. Royse makes the same point with personal force. “I would be dead right now if not for multicancer early-detection testing,” Mr. Royse told an FDA advisory committee last fall. “The longer the FDA waits, the more people are going to die. It’s that simple.”

I’m standing before them not as an ambassador of certainty or a font of unassailable verities but as an emissary of doubt. I want to give them intelligent questions, not final answers. I want to teach them how much they have to learn — and how much they will always have to learn.

each component of it was about the same quality: humility.

The grammar-and-spelling bit was about surrendering to an established and easily understood way of doing things that eschewed wild individualism in favor of a common mode of communication. It showed respect for tradition, which is a force that binds us, a folding of the self into a greater whole

The voices bit — well, that’s obvious. It’s a reminder that we share the stages of our communities, our countries, our worlds, with many other actors and should conduct ourselves in a manner that recognizes this fact. A

I’d also been delivering that spiel for more than two years before I realized that humility is the antidote to grievance.

We live in an era defined and overwhelmed by grievance — by too many Americans’ obsession with how they’ve been wronged and their insistence on wallowing in ire

This anger reflects a pessimism that previous generations didn’t feel

They promote a self-obsession at odds with community, civility, comity and compromise. It’s a problem of humility.

They elevated how they viewed the world and what they wanted over tradition, institutional stability, law, order.

The Jan. 6 insurrectionists were delusional, frenzied, savage. But above all, they were unhumble. They decided that they held the truth, no matter all the evidence to the contrary.

anti-Trumps will be our salvation, and I say that not along partisan or ideological lines. I’m talking about character and how a society holds itself together.

It does that with concern for the common good, with respect for the institutions and procedures that protect that and with political leaders who ideally embody those traits or at least promote them.

He was fond of quoting Philippians 2:3, which he invoked as a lodestar for his administration. “Do nothing out of selfish ambition or vain conceit,” it says. “Rather, in humility value others above yourself.”

Governing, as opposed to demagoguery, is about earning others’ trust and cooperation. Exhibiting a willingness to listen to and to hear them goes a long way toward that.

“Insight and knowledge come from curiosity and humility,” Mr. Baker wrote in a 2022 book, “Results,” coauthored with his chief of staff, Steve Kadish, a Democrat. “Snap judgments — about people or ideas — are fueled by arrogance and conceit. They create blind spots and missed opportunities. Good ideas and interesting ways to accomplish goals in public life exist all over the place if you have the will, the curiosity, and the humility to find them.”

‘Yes, there’s demanding, but there’s also asking,’” he recalled. “And one is not the enemy of the other. People don’t like being accused, people don’t like being condemned, people don’t like being alienated. It’s a matter of conversation and persuasion.”

the message delivered by Loretta Ross, a longtime racial justice and human rights advocate, through her teaching, public speaking and writing. Troubled by the frequent targeting and pillorying of people on social media, she urged the practice of calling in rather than calling out those who’ve upset you. “Call-outs make people fearful of being targeted,” she wrote in a guest essay for Times Opinion. “People avoid meaningful conversations when hypervigilant perfectionists point out apparent mistakes, feeding the cannibalistic maw of the cancel culture.” Instead, she advised, engage them. If you believe they need enlightenment, try that route, “without the self-indulgence of drama,” she wrote.

She was also recognizing other people’s right to disagree — to live differently, to talk differently. Pluralism is as much about that as it is about a multiracial, multifaith, multigender splendor.

Tolerance shares DNA with respect. It recognizes that other people have rights and inherent value even when we disagree vehemently with them.

we mustn’t treat every wound, every obstacle, as some cosmic outrage or mortal danger. We mustn’t lose sight of the struggle, imperfection and randomness of life. We mustn’t overstate our vulnerability and exaggerate our due.

While grievance blows our concerns out of proportion, humility puts them in perspective. While grievance reduces the people with whom we disagree to caricature, humility acknowledges that they’re every bit as complex as we are — with as much of a stake in creating a more perfect union.

“We’ve tried to rap in pure French, but nobody was listening to us,” said Jean Patrick Niambé, known as Dofy, a 24-year-old Ivorian hip-hop artist listening to Marla on the rooftop. “So we create words from our own realities, and then they spread.”

The youth population in Africa is surging while the rest of the world grays. Demographers predict that by 2060, up to 85 percent of French speakers will live on the African continent. That’s nearly the inverse of the 1960s, when 90 percent of French speakers lived in European and other Western countries.

Nearly half of the countries in Africa were at one time French colonies or protectorates, and most of them use French as their official language.

President Emmanuel Macron of France said in a 2019 speech: “France must take pride in being essentially one country among others that learns, speaks, writes in French.”

“I could not have done it sooner,” he says. “I don’t think anybody could have done it sooner. Because I was the first one.” 

By the late 1960s, he was managing TI’s integrated-circuit division. Before long, he was running the entire semiconductor group. 

He transferred to the Massachusetts Institute of Technology, where he studied mechanical engineering, earned his master’s degree and would have stayed for his Ph.D. if he hadn’t failed the qualifying exam. Instead, he got his first job in semiconductors and moved to Texas Instruments in 1958

he came along as the integrated circuit was being invented, and his timing couldn’t have been any better, as Chang belonged to the first generation of semiconductor geeks. He developed a reputation as a tenacious manager who could wring every possible improvement out of production lines, which put his career on the fast track.

Chang grew up dreaming of being a writer—a novelist, maybe a journalist—and he planned to major in English literature at Harvard University. But after his freshman year, he decided that what he actually wanted was a good job

“They talk about life-work balance,” he says. “That’s a term I didn’t even know when I was their age. Work-life balance. When I was their age, if there was no work, there was no life.” 

These days, TSMC is investing $40 billion to build plants in Arizona, but the project has been stymied by delays, setbacks and labor shortages, and Chang told me that some of TSMC’s young employees in the U.S. have attitudes toward work that he struggles to understand. 

Chang says he wouldn’t have taken the risk of moving to Taiwan if he weren’t financially secure. In fact, he didn’t take that same risk the first time he could have.

“The closer the industry match,” they wrote, “the greater the success rate.” 

By then, Chang knew that he wasn’t long for Texas Instruments. But his stock options hadn’t vested, so he turned down the invitation to Taiwan. “I was not financially secure yet,” he says. “I was never after great wealth. I was only after financial security.” For this corporate executive in the middle of the 1980s, financial security equated to $200,000 a year. “After tax, of course,” he says. 

Chang’s situation had changed by the time Li called again three years later. He’d exercised a few million dollars of stock options and bought tax-exempt municipal bonds that paid enough for him to be financially secure by his living standards. Once he’d achieved that goal, he was ready to pursue another one. 

“There was no certainty at all that Taiwan would give me the chance to build a great semiconductor company, but the possibility existed, and it was the only possibility for me,” Chang says. “That’s why I went to Taiwan.” 

Not long ago, a team of economists investigated whether older entrepreneurs are more successful than younger ones. By scrutinizing Census Bureau records and freshly available Internal Revenue Service data, they were able to identify 2.7 million founders in the U.S. who started companies between 2007 and 2014. Then they looked at their ages.

The average age of those entrepreneurs at the founding of their companies was 41.9. For the fastest-growing companies, that number was 45. The economists also determined that 50-year-old founders were almost twice as likely to achieve major success as 30-year-old founders, while the founders with the lowest chance of success were the ones in their early 20s

“Successful entrepreneurs are middle-aged, not young,” they wrote in their 2020 paper.  

Silicon Valley’s venture capitalists throw money at talented young entrepreneurs in the hopes they will start the next trillion-dollar company. They have plentiful energy, insatiable ambition and the vision to peek around corners and see the future. What they don’t typically have are mortgages, family obligations and other adult responsibilities to distract them or diminish their appetite for risk. Chang himself says that younger people are more innovative when it comes to science and technical subjects. 

But in business, older is better. Entrepreneurs in their 40s and 50s may not have the exuberance to believe they will change the world, but they have the experience to know how they actually can. Some need years of specialized training before they can start a company. In biotechnology, for example, founders are more likely to be college professors than college dropouts. Others require the lessons and connections they accumulate over the course of their careers. 

one more finding from their study of U.S. companies that helps explain the success of a chip maker in Taiwan. It was that prior employment in the area of their startups—both the general sector and specific industry—predicted “a vastly higher probability” of success.

Chang was such a workaholic that he made sales calls on his honeymoon and had no patience for those who didn’t share his drive

Morris Chang had 30 years of experience in his industry when he decided to uproot his life and move to another continent. He knew more about semiconductors than just about anyone on earth—and certainly more than anyone in Taiwan. As soon as he started his job at the Industrial Technology Research Institute, Chang was summoned to K.T. Li’s office and given a second job. “He felt I should start a semiconductor company in Taiwan,”

“I decided right away that this could not be the kind of great company that I wanted to build at either Texas Instruments or General Instrument,”

TI handled every part of chip production, but what worked in Texas would not translate to Taiwan. The only way that he could build a great company in his new home was to make a new sort of company altogether, one with a business model that would exploit the country’s strengths and mitigate its many weaknesses.

Chang determined that Taiwan had precisely one strength in the chip supply chain. The research firm that he was now running had been experimenting with semiconductors for the previous 10 years. When he studied that decade of data, Chang was pleasantly surprised by Taiwan’s yields, the percentage of working chips on silicon wafers. They were almost twice as high in Taiwan as they were in the U.S., he said. 

“People were ingrained in thinking the secret sauce of a successful semiconductor company was in the wafer fab,” Campbell told me. “The transition to the fabless semiconductor model was actually pretty obvious when you thought about it. But it was so against the prevailing wisdom that many people didn’t think about it.” 

Taiwan’s government took a 48% stake, with the rest of the funding coming from the Dutch electronics giant Philips and Taiwan’s private sector, but Chang was the driving force behind the company. The insight to build TSMC around such an unconventional business model was born from his experience, contacts and expertise. He understood his industry deeply enough to disrupt it. 

“TSMC was a business-model innovation,” Chang says. “For innovations of that kind, I think people of a more advanced age are perhaps even more capable than people of a younger age.”

the personal philosophy that he’d developed over the course of his long career. “To be a partner to our customers,” he says. That founding principle from 1987 is the bedrock of the foundry business to this day, as TSMC says the key to its success has always been enabling the success of its customers.  

TSMC manufactures chips in iPhones, iPads and Mac computers for Apple, which manufactures a quarter of TSMC’s net revenue. Nvidia is often called a chip maker, which is curious, because it doesn’t make chips. TSMC does. 

Churning out identical copies of a single chip for an iPhone requires one TSMC fab to produce more than a quintillion transistors—that is, one million trillions—every few months. In a year, the entire semiconductor industry produces “more transistors than the combined quantity of all goods produced by all other companies, in all other industries, in all human history,” Miller writes. 

I asked how he thought about success when he moved to Taiwan. “The highest degree of success in 1985, according to me, was to build a great company. A lower degree of success was at least to do something that I liked to do and I wanted to do,” he says. “I happened to achieve the highest degree of success that I had in mind.” 

Since coming to power in 2019, Bukele has declared a still-to-be-rescinded state of exception, suspended the Salvadorean constitution, and locked up some 70,000 alleged gang members without due process.

This trait also makes him a touchstone for the Right-wing movement that I predict will replace “conservatism” in the 21st century. This outlook owes more to the Italian Futurist Filippo Marinetti than conservatives of the G.K. Chesterton variety

yet, Bukele’s strongman tactics have made him wildly popular with Salvadoreans, who doubtless enjoy a reported 70% reduction in the country’s previously extremely high murder rate. They have also made Bukele a rock star for the online Right. This group, fond of complaining about spineless leaders, fraying Western law and order, and the bleeding-away of political agency into international institutions and NGOs, regards the spectacle of a strongman leader with good social media game as something like a fantasy made flesh.

Arguably, it’s as much his embrace of technology that accords Bukele the mantle of poster-boy for a futuristic Right. Whether in his extremely online presence, his (admittedly not completely successful) embrace of Bitcoin as legal tender, or the high-tech, recently rebuilt National Library, funded by Beijing and serving more as showcase for futuristic technologies than as reading-room

Western critics, though, point to allegations that he has corrupted institutions by packing them with allies, not to mention, according to Amnesty International, “concealed and distorted public information, backed actions to undermine civic space, militarised public security, and used mass arrests and imprisonment as the sole strategies for counteracting violence in the country”.

is perhaps most visibly embodied in American technologists such as Elon Musk, Mark Andreessen or Peter Thiel. As a worldview, it is broadly pro-capitalist, enthusiastically pro-technology and unabashedly hierarchical, as well as sometimes also scornful of Christian-inflected concern for the weak.

We might call it, rudely, “space fascism”, though N.S. Lyons’s formulation “Right-wing progressivism” is probably more accurate. Among its adherents, high-tech authoritarianism is a feature, not a bug, and egalitarianism is for fools. Thinkers such as Curtis Yarvin propose an explicitly neo-monarchical model for governance; Thiel has declared that: “I no longer believe freedom and democracy are compatible.”

El Salvador is thus the most legible real-world instance of something like a Right-wing progressive programme in practice. And along with the tech enthusiasm and public-order toughness, the third distinctive feature of this programme can be gleaned: a desire not to end international migration, but to restrict it to elites.

For Right-wing progressives, polities are not necessarily premised on ethnic or cultural homogeneity — at least not for elites. Rather, this is a vision of statehood less based on affinity, history or even ethnicity, and more on a kind of opt-in, utility-maximisation model

As a worldview, it’s jarring to cultural conservatives, who generally value thick ties of shared history and affinity

Right-wing progressives generally accord greater political value to gifted, high-productivity foreigners than any slow-witted, unproductive coethnic: those within Right-wing progressive circles propose, and in some cases are already working on, opt-in startup cities and “network states” that would be, by definition, highly selective about membership.

As for those still wedded to the 20th-century idea that being Right-wing necessarily means ethnicity-based nationalism, they are likely to find this outlook bewildering.

Yet it’s still more heretical to egalitarian progressives, for whom making migration and belonging an elite privilege offends every premise of inclusion and social justice.

Right-wing progressives, by contrast, propose to learn from the immigration policies of polities such as Singapore and the Gulf states, and avert the political challenges posed by ethnic voting blocs by imposing tiered citizenship for low-skilled migrants, while courting the wealth and productivity of international elites

Bukele’s proposal suggests a pragmatic two-tier Right-wing progressive migration policy that courts rich, productive, geographically rootless international “Anywheres” of the kind long understood to have more affinity with one another than with less wealthy and more rooted “Somewheres” — but to do so while explicitly protecting cultural homogeneity on behalf of the less-mobile masses.

There are larger structural reasons for such pragmatism, not least that population growth is slowing or going into reverse across most of the planet.

At the same time, impelled by easier transportation, climate change, social-media promises of better lives elsewhere, and countless other reasons, people everywhere are on the move. As such, like a global game of musical chairs, a battle is now on for who ends up where, once the music stops — and on what terms.

How do you choose who is invited? And how do you keep unwanted demographics out? Within an egalitarian progressive framework, these are simply not questions that one may ask

Within the older, cultural conservative framework, meanwhile, all or most migration is viewed with suspicion.

The Right-wing progressive framework, by contrast, is upbeat about migration — provided it’s as discerning as possible, ideally granting rights only to elite incomers and filtering others aggressively by demographics, for example an assessment of the statistical likeliho

od of committing crime or making a net economic contribution.

In Britain, meanwhile, whatever happens to the Tories, I suspect we’ll see more of the Right-wing progressives. I find many of their policies unnerving, especially on the biotech side; but theirs is a political subculture with optimism and a story about the future, two traits that go a long way in politics.

Bonobos became famous for showing that nature didn’t always have to be red in tooth and claw. “Bonobos are an icon for peace and love, the world’s ‘hippie chimps,’” Sally Coxe, a conservationist, said in 2006.

Because bonobos live in remote, swampy rainforests, it has been much more difficult to observe them in the wild than chimpanzees. More recent research has shown that bonobos live a more aggressive life than their reputation would suggest.

In a study based on thousands of hours of observations in the wild published on Friday, for example, researchers found that male bonobos commit acts of aggression nearly three times as often as male chimpanzees do.

“There is no ‘hippie ape,’”

As our closest living relatives, bonobos and chimpanzees can offer us clues about the roots of human behavior. We and the two species share a common ancestor that lived about 7 million years ago. About 5 million years later, bonobos split off from chimpanzees.

In 2012, a trio of Harvard researchers proposed that bonobos evolved much like dogs did. Less aggressive wolves were not as likely to be killed by humans, which over time led to the emergence of dogs. In a similar fashion, the researchers argued, female bonobos preferred to mate with less aggressive males, giving birth to less aggressive offspring.

The researchers called their idea the self-domestication hypothesis. In later years, they speculated that humans may have undergone a self-domestication of their own.

Dr. Mouginot soon became perplexed, as she saw that male bonobos acted aggressively on a regular basis. Unlike male chimpanzees, who started their days in a mellow mood, the male bonobos seemed to wake up ready for a fight.

She and her colleagues trained field assistants, who made more observations throughout the pandemic. The new analysis, based on 9,300 hours of observations on 12 male bonobos and 14 male chimpanzees, found that bonobos committed aggressive acts 2.8 times as frequently as than the chimpanzees did.

Dr. Mouginot found that the frequent bonobo aggressions almost always involved a single male attacking another male. Chimpanzees, in contrast, often ganged up to attack a victim.

the study set a new standard for comparing aggression in bonobos and chimpanzees.

Dr. Mouginot speculated that male chimpanzees engage in one-on-one aggression less often because it poses bigger dangers: A victim of aggression may not want to go on a border patrol with the perpetrator, for example. Or he may bring back some of his own allies to wreak vengeance.

It may be easier for male bonobos to get away with aggression, Dr. Mouginot said, because in their female-dominated society they don’t face the risks that come with male alliances. “I think that’s why we see more aggression in bonobos — because it’s less risky to act aggressively against other males,”

the apes that carried out the most aggressive acts were also the ones who mated most often.

parts of the self-domestication hypothesis “clearly need refinement.” It may be important to consider the effect that different kinds of aggression have on a species, rather than lumping them altogether, he said.

Still, he argued that the differences between the two species remained significant. “Chimpanzees murder, and bonobos don’t,

For the first time since the first World Happiness Report was published in 2012, the United States fell out of the Top 20 and dropped to 23rd, pushed down by cratering attitudes of Americans under 30.

Americans have long been an unhappy bunch. They have never ranked in the Top 10 of the World Happiness Report, which is based on how respondents in different countries rate their own happiness.

cited the disruptions to life brought about by the coronavirus pandemic as a chief cause of mental health challenges among younger Americans.

The happiest young people are in Lithuania, while the unhappiest are in Afghanistan.

“I have never seen such an extreme change,” John Helliwell, an economist and a co-author of the report, said in an interview, referring to the drop in happiness among younger people. “This has all happened in the last 10 years, and it’s mainly in the English-language countries. There isn’t this drop in the world as a whole.”

Respondents were asked — among other prompts — to think of their life as a ladder and to rate it on a scale of one to 10, with 10 being the best possible life.

this was the first time that the consortium separated results by age, finding disparities in the views of younger and older Americans. Among the 143 countries surveyed, the United States ranked 10th for people 60 and older, but 62nd for people under 30.

Jade Song, a 27-year-old novelist, counted herself among those who had become increasingly unhappy in recent years.

“Many of the things that would have normally taken place for people, particularly high school young adults, did not take place,” he added. “And that is still occurring.”

“It’s mostly because as an adult you suddenly become aware of all the world news and you pay attention more to what you can control, and you realize that there is so little you can control,” Ms. Song, who was not part of the study, said in an interview. “Even if you’re going to protests or paying your rent and bills all on time, it’s so difficult, especially now, to break free from how you’re living your life when you realize how little impact your actions actually have on a broader level.”

There is a silver lining, though

In 2022, a Harvard University study showed that well-being among young adults in the United States had declined in the previous 20 years. Young people — those between the ages of 18 and 25 — reported the lowest levels of happiness compared with other age groups, as well as the poorest mental and physical health, sense of purpose, character, virtue, close social relationships and financial stability

Similar findings have emerged in Britain and Canada.

“One factor, which we’re all thinking about, is social media,” said Dr. Robert Waldinger, the director of the Harvard Study of Adult Development

“Because there’s been some research that shows that depending on how we use social media, it lowers well-being, it increases rates of depression and anxiety, particularly among young girls and women, teenage girls.”

In addition, Dr. Waldinger said, the negative feedback loop from news consumption has become a contributing factor.

“There’s also a lot of anxiety about the state of the world,” he said. “About climate change. About all of the polarization that we’re seeing.”

in some other countries, such as Croatia, Switzerland and Austria, the World Happiness Report shows that young people are becoming happier.

“Part of the problem is that we have this huge expectation of happiness in America,” said Eric Weiner, the author of “The Geography of Bliss,” and so we suffer partly from the unhappiness of not being happy and the expectation that we should be happy. And not every country in the world has that.”

“There’s an assumption that if you’re American, you’re wealthy and you’re high tech and you’re successful; you should be happy,” he said. “There’s a lot of data that shows that the greater your expectations, the less you’re happy.”

The expectations for young people like Ms. Song, the novelist, said have shifted.

“We have less to look forward to,” she said. “Because in the future, there’s going to be climate change that will affect the way we live. I think there’s less of a clear-cut trajectory for our life paths, because for so long, it was so easy just to know that you could go get married and have your 2.5 kids, and then pay for your house. But now that path is a lot more closed.”

“The literature is clear in practice — the effect that this had on socialization, pro-social behavior, if you will, and the ability for people to feel connected and have a community,”

“A, this angst is very local and, B, it’s very recent, which means, C, it’s not fundamental and going to last forever,” he said. “If it has been created that quickly, it could be removed that quickly.”
