This is a delayed but inescapable consequence of China’s birth trends from the era of the notorious one-child policy (1980-2015)

Beijing thus far has ignored this looming crisis because planners don’t prepare for things they don’t track. Officials don’t regard data on the family as relevant to statecraft or security. So statistics tally males and females—not uncles, sisters, cousins, widows.

We estimate past patterns and project trends through demographic modeling—simulations replicating China’s available population numbers—while “building” family trees consistent with those figures. We can approximate nationwide changes in China’s extended family networks in the past with reasonable validity and describe what lies ahead with fair confidence.

we are only now living through the era of “peak kin” in China. In terms of sheer numbers, Chinese networks of blood relatives were never nearly as thick as at the start of the 21st century.

Because of dramatic postwar improvements in health and mortality, men and women in their 40s today have on average five times as many living cousins as in 1960.

China’s “kin explosion” may be an important, heretofore unobserved factor in China’s remarkable economic performance since Mao Zedong’s death in 1976.

China is now on the cusp of a severe and unavoidable “kin crash,” driven by prolonged subreplacement fertility

China’s rising generations will likely have fewer living relatives than ever before in Chinese history.

A “kin famine” will thus unfold unforgivingly over the next 30 years—starting now. As it intensifies, the Chinese family—the most important institution protecting Chinese people against adversity in bad times and helping them seize opportunity in good times—will increasingly falter in both these crucial functions.

China’s withering of the family is set to collide with a tsunami of new social need from the country’s huge elderly population, whose ranks will more than double between 2020 and 2050

By 2050 living parents and in-laws will outnumber children for middle-aged Chinese men and women. Thus exigency may overturn basic familial arrangements that have long been taken for granted. The focus of the family in China will necessarily turn from the rearing of the young to the care of the old.

The reliability and durability of familial bonds of duty will be an increasingly critical question—perhaps even a matter of life and death for many, including frail and impecunious elders in the Chinese hinterlands

growing numbers of men in decades ahead will enter old age without spouses or children—the traditional sources of support for the elderly.

by 2050, 18% of China’s men in their 60s will have no living descendants, twice the fraction today.

who will look after these unfortunates?

Still worse than the macroeconomic implications of old-age dependency may be the effect of China’s family crisis on the so-called micro-foundations of the national economy—the little things that make markets work.

Since earliest recorded history, China’s guanxi networks, a distinctive form of special relationships and professional connections, have helped get business done by reducing uncertainty and transaction costs. The proliferation of blood relatives was likely a powerful stimulant for growth during the era of China’s phenomenal upswing.

the kin dearth may prove an economic depressant well beyond what current “head count” projections suggest.

China’s coming family revolution could easily conduce to a rise in personal risk aversion. Risk aversion may in turn dampen mobility, including migration.

Less migration means less urbanization, which means less growth—and possibly still more pessimism and risk aversion.

If the waning of the family requires China to build a huge social welfare state over the coming generation, as we surmise it will, Beijing would have that much less wherewithal for influencing events abroad through economic diplomacy and defense policy.

by 2050 at least half of China’s overall pool of male military-age manpower will be made up of only children. Any encounter by China’s security forces involving significant loss of life will presage lineage extinction for many Chinese families.

Autocracies are typically tolerant of casualties—but maybe not in the only-child China of today and the decades ahead.

Failure to contemplate the implications of the coming changes in Chinese family structure could prove a costly blind spot for the Communist Party. Blind spots expose governments to the risk of strategic surprise. The consequences of social, economic and political risks tend to be greatest when states aren’t prepared for them.

“My first and biggest wish is that we had known early that Covid-19 was airborne,”

, “Once you’ve realized that, it informs an entirely different strategy for protection.” Masking, ventilation and air cleaning become key, as well as avoiding high-risk encounters with strangers, he says.

Instead of washing our produce and wearing hand-sewn cloth masks, we could have made sure to avoid superspreader events and worn more-effective N95 masks or their equivalent. “We could have made more of an effort to develop and distribute N95s to everyone,” says Dr. Volckens. “We could have had an Operation Warp Speed for masks.”

We didn’t realize how important clear, straight talk would be to maintaining public trust. If we had, we could have explained the biological nature of a virus and warned that Covid-19 would change in unpredictable ways.  

In the face of a pandemic, he says, the public needs an early basic and blunt lesson in virology

“The science is really important, but if you don’t get the trust and communication right, it can only take you so far,”

and mutates, and since we’ve never seen this particular virus before, we will need to take unprecedented actions and we will make mistakes, he says.

Since the public wasn’t prepared, “people weren’t able to pivot when the knowledge changed,”

By the time the vaccines became available, public trust had been eroded by myriad contradictory messages—about the usefulness of masks, the ways in which the virus could be spread, and whether the virus would have an end date.

, the absence of a single, trusted source of clear information meant that many people gave up on trying to stay current or dismissed the different points of advice as partisan and untrustworthy.

We didn’t know how difficult it would be to get the basic data needed to make good public-health and medical decisions. If we’d had the data, we could have more effectively allocated scarce resources

For much of the pandemic, doctors, epidemiologists, and state and local governments had no way to find out in real time how many people were contracting Covid-19, getting hospitalized and dying

Doctors didn’t know what medicines worked. Governors and mayors didn’t have the information they needed to know whether to require masks. School officials lacked the information needed to know whether it was safe to open schools.

people didn’t know whether it was OK to visit elderly relatives or go to a dinner party.

just months before the outbreak of the pandemic, the Council of State and Territorial Epidemiologists released a white paper detailing the urgent need to modernize the nation’s public-health system still reliant on manual data collection methods—paper records, phone calls, spreadsheets and faxes.

While the U.K. and Israel were collecting and disseminating Covid case data promptly, in the U.S. the CDC couldn’t. It didn’t have a centralized health-data collection system like those countries did, but rather relied on voluntary reporting by underfunded state and local public-health systems and hospitals.

doctors and scientists say they had to depend on information from Israel, the U.K. and South Africa to understand the nature of new variants and the effectiveness of treatments and vaccines. They relied heavily on private data collection efforts such as a dashboard at Johns Hopkins University’s Coronavirus Resource Center that tallied cases, deaths and vaccine rates globally.

With good data, Dr. Ranney says, she could have better managed staffing and taken steps to alleviate the strain on doctors and nurses by arranging child care for them.

To solve the data problem, Dr. Ranney says, we need to build a public-health system that can collect and disseminate data and acts like an electrical grid. The power company sees a storm coming and lines up repair crews.

If we’d known how damaging lockdowns would be to mental health, physical health and the economy, we could have taken a more strategic approach to closing businesses and keeping people at home.

t many doctors say they were crucial at the start of the pandemic to give doctors and hospitals a chance to figure out how to accommodate and treat the avalanche of very sick patients.

The measures reduced deaths, according to many studies—but at a steep cost.

The lockdowns didn’t have to be so harmful, some scientists say. They could have been more carefully tailored to protect the most vulnerable, such as those in nursing homes and retirement communities, and to minimize widespread disruption.

Lockdowns could, during Covid-19 surges, close places such as bars and restaurants where the virus is most likely to spread, while allowing other businesses to stay open with safety precautions like masking and ventilation in place.  

If England’s March 23, 2020, lockdown had begun one week earlier, the measure would have nearly halved the estimated 48,600 deaths in the first wave of England’s pandemic

If the lockdown had begun a week later, deaths in the same period would have more than doubled

The key isn’t to have the lockdowns last a long time, but that they are deployed earlier,

It is possible to avoid lockdowns altogether. Taiwan, South Korea and Hong Kong—all countries experienced at handling disease outbreaks such as SARS in 2003 and MERS—avoided lockdowns by widespread masking, tracking the spread of the virus through testing and contact tracing and quarantining infected individuals.

Had we known that even a mild case of Covid-19 could result in long Covid and other serious chronic health problems, we might have calculated our own personal risk differently and taken more care.

Early in the pandemic, public-health officials were clear: The people at increased risk for severe Covid-19 illness were older, immunocompromised, had chronic kidney disease, Type 2 diabetes or serious heart conditions

t had the unfortunate effect of giving a false sense of security to people who weren’t in those high-risk categories. Once case rates dropped, vaccines became available and fear of the virus wore off, many people let their guard down, ditching masks, spending time in crowded indoor places.

it has become clear that even people with mild cases of Covid-19 can develop long-term serious and debilitating diseases. Long Covid, whose symptoms include months of persistent fatigue, shortness of breath, muscle aches and brain fog, hasn’t been the virus’s only nasty surprise

In February 2022, a study found that, for at least a year, people who had Covid-19 had a substantially increased risk of heart disease—even people who were younger and had not been hospitalized

respiratory conditions.

Some scientists now suspect that Covid-19 might be capable of affecting nearly every organ system in the body. It may play a role in the activation of dormant viruses and latent autoimmune conditions people didn’t know they had

 A blood test, he says, would tell people if they are at higher risk of long Covid and whether they should have antivirals on hand to take right away should they contract Covid-19.

If the risks of long Covid had been known, would people have reacted differently, especially given the confusion over masks and lockdowns and variants? Perhaps. At the least, many people might not have assumed they were out of the woods just because they didn’t have any of the risk factors.

“No one believed me that working for Elon was the way it was until they saw how he operated Twitter,” Bernal said, calling Twitter “just the tip of the iceberg on how he operates Tesla.”

In April 2019, at a showcase dubbed “Autonomy Investor Day,” Musk made perhaps his boldest prediction as Tesla’s chief executive. “By the middle of next year, we’ll have over a million Tesla cars on the road with full self-driving hardware,” Musk told a roomful of investors. The software updates automatically over the air, and Full Self-Driving would be so reliable, he said, the driver “could go to sleep.”

Investors were sold. The following year, Tesla’s stock price soared, making it the most valuable automaker and helping Musk become the world’s richest person

To deliver on his promise, Musk assembled a star team of engineers willing to work long hours and problem solve deep into the night. Musk would test the latest software on his own car, then he and other executives would compile “fix-it” requests for their engineers.

Those patchwork fixes gave the illusion of relentless progress but masked the lack of a coherent development strategy, former employees said. While competitors such as Alphabet-owned Waymo adopted strict testing protocols that limited where self-driving software could operate, Tesla eventually pushed Full Self-Driving out to 360,000 owners — who paid up to $15,000 to be eligible for the features — and let them activate it at their own discretion.

Tesla’s philosophy is simple: The more data (in this case driving) the artificial intelligence guiding the car is exposed to, the faster it learns. But that crude model also means there is a lighter safety net. Tesla has chosen to effectively allow the software to learn on its own, developing sensibilities akin to a brain via technology dubbed “neural nets” with fewer rules, the former employees said. While this has the potential to speed the process, it boils down to essentially a trial and error method of training.

Radar originally played a major role in the design of the Tesla vehicles and software, supplementing the cameras by offering a reality check of what was around, particularly if vision might be obscured. Tesla also used ultrasonic sensors, shorter-range devices that detect obstructions within inches of the car. (The company announced last year it was eliminating those as well.)

Even with radar, Teslas were less sophisticated than the lidar and radar-equipped cars of competitors.“One of the key advantages of lidar is that it will never fail to see a train or truck, even if it doesn’t know what it is,” said Brad Templeton, a longtime self-driving car developer and consultant who worked on Google’s self-driving car. “It knows there is an object in front and the vehicle can stop without knowing more than that.”

Toward the end of 2020, Autopilot employees turned on their computers to find in-house workplace monitoring software installed, former employees said. It monitored keystrokes and mouse clicks, and kept track of their image labeling. If the mouse did not move for a period of time, a timer started — and employees could be reprimanded, up to being fired, for periods of inactivity, the former employees said.

Some of the people who spoke with The Post said that approach has introduced risks. “I just knew that putting that software out in the streets would not be safe,” said a former Tesla Autopilot engineer who spoke on the condition of anonymity for fear of retaliation. “You can’t predict what the car’s going to do.”

Some of the people who spoke with The Post attributed Tesla’s sudden uptick in “phantom braking” reports — where the cars aggressively slow down from high speeds — to the lack of radar. The Post analyzed data from the National Highway Traffic Safety Administration to show incidences surged last year, prompting a federal regulatory investigation.

The data showed reports of “phantom braking” rose to 107 complaints over three months, compared to only 34 in the preceding 22 months. After The Post highlighted the problem in a news report, NHTSA received about 250 complaints of the issue in a two-week period. The agency opened an investigation after, it said, it received 354 complaints of the problem spanning a period of nine months.

“It’s not the sole reason they’re having [trouble] but it’s big a part of it,” said Missy Cummings, a former senior safety adviser for NHTSA, who has criticized the company’s approach and recused herself on matters related to Tesla. “The radar helped detect objects in the forward field. [For] computer vision which is rife with errors, it serves as a sensor fusion way to check if there is a problem.”

Musk, as the chief tester, also asked for frequent bug fixes to the software, requiring engineers to go in and adjust code. “Nobody comes up with a good idea while being chased by a tiger,” a former senior executive recalled an engineer on the project telling him

Musk’s resistance to suggestions led to a culture of deference, former employees said. Tesla fired employees who pushed back on his approach. The company was also pushing out so many updates to its software that in late 2021, NHTSA publicly admonished Tesla for issuing fixes without a formal recall notice.

Tesla engineers have been burning out, quitting and looking for opportunities elsewhere. Andrej Karpathy, Tesla’s director of artificial intelligence, took a months-long sabbatical last year before leaving Tesla and taking a position this year at OpenAI, the company behind language-modeling software ChatGPT.

One of the former employees said that he left for Waymo. “They weren’t really wondering if their car’s going to run the stop sign,” the engineer said. “They’re just focusing on making the whole thing achievable in the long term, as opposed to hurrying it up.”

That’s no accident. In the three decades since the end of the Soviet Union, those men have faced industrial collapse, the disappearance of millions of jobs and declining life expectancy. The war promises to change that downward trajectory, transforming the losers of the past three decades into new heroes

For many Russian men and their families, the war may be a horror. But it’s also the last opportunity to fix their lives.

First, there’s the money. The federal base salary for a soldier is about $2,500 a month, with payment of $39,000 for wounding and up to $65,000 in the case of death. Compared with a median monthly salary of $545, this is a handsome reward — even more so for the approximately 15.3 million Russians living below the poverty line.

there’s much more on offer, too. For those coming back from the front, the state promises fast-tracked entry into civil service jobs, health insurance, free public transportation, as well as free university education and free food at school for their children. And for those who were imprisoned and joined the Wagner private military company, the state grants freedom.

Today’s soldiers live in the shadows of the generation that won the war against Nazism. In Russian public culture, no honor is higher than to be a veteran of the “Great Patriotic War,” something the regime has capitalized on by framing today’s war as a kind of historical re-enactment of World War II.

As one soldier wrote on Telegram in February, the war confers “a sense of belonging to the great male deed, the deed of defending our Motherland.”

By allowing men to escape the difficulties of everyday life — with its low pay and routine frustrations — the war offers a restoration of male self-worth. These men, at last, matter.

Feelings of inferiority, too, are swept aside in the fraternal atmosphere of the front. “It doesn’t matter who you are, how you look,” as one soldier put it. In the communal life of conflict, many of the distinctions of civilian life dissolve. War is an equalizer.

Mistrust of the rich, belief that sanctions actually strengthen the economy and disdain for émigrés all attest to a class-based experience of the conflict. By participating in the war, millions of Russians at the bottom of the social ladder can emerge as the country’s true heroes, ready for the ultimate sacrifice. The risk may be grave and the financial reward uncertain. But the chance to rise in esteem and respect makes the effort worthwhile.

The longer the war drags on, bringing more casualties, loss and broken promises, the harder it may become to sustain such levels of acceptance

it may not. Collective emotional turmoil could deepen the feeling that the war must be won, no matter what. In the absence of an alternative vision of the future, Vladimir Putin and his war will continue to hold sway.

The key issue is not “human-competitive” intelligence (as the open letter puts it); it’s what happens after AI gets to smarter-than-human intelligence. Key thresholds there may not be obvious, we definitely can’t calculate in advance what happens when, and it currently seems imaginable that a research lab would cross critical lines without noticing.

Many researchers steeped in these issues, including myself, expect that the most likely result of building a superhumanly smart AI, under anything remotely like the current circumstances, is that literally everyone on Earth will die. Not as in “maybe possibly some remote chance,” but as in “that is the obvious thing that would happen.”

It’s not that you can’t, in principle, survive creating something much smarter than you; it’s that it would require precision and preparation and new scientific insights, and probably not having AI systems composed of giant inscrutable arrays of fractional numbers.

Absent that caring, we get “the AI does not love you, nor does it hate you, and you are made of atoms it can use for something else.”

Without that precision and preparation, the most likely outcome is AI that does not do what we want, and does not care for us nor for sentient life in general. That kind of caring is something that could in principle be imbued into an AI but we are not ready and do not currently know how.

The likely result of humanity facing down an opposed superhuman intelligence is a total loss

To visualize a hostile superhuman AI, don’t imagine a lifeless book-smart thinker dwelling inside the internet and sending ill-intentioned emails. Visualize an entire alien civilization, thinking at millions of times human speeds, initially confined to computers—in a world of creatures that are, from its perspective, very stupid and very slow. A sufficiently intelligent AI won’t stay confined to computers for long. In today’s world you can email DNA strings to laboratories that will produce proteins on demand, allowing an AI initially confined to the internet to build artificial life forms or bootstrap straight to postbiological molecular manufacturing.

There’s no proposed plan for how we could do any such thing and survive. OpenAI’s openly declared intention is to make some future AI do our AI alignment homework. Just hearing that this is the plan ought to be enough to get any sensible person to panic. The other leading AI lab, DeepMind, has no plan at all.

An aside: None of this danger depends on whether or not AIs are or can be conscious; it’s intrinsic to the notion of powerful cognitive systems that optimize hard and calculate outputs that meet sufficiently complicated outcome criteria.

I didn’t also mention that we have no idea how to determine whether AI systems are aware of themselves—since we have no idea how to decode anything that goes on in the giant inscrutable arrays—and therefore we may at some point inadvertently create digital minds which are truly conscious and ought to have rights and shouldn’t be owned.

I refrained from signing because I think the letter is understating the seriousness of the situation and asking for too little to solve it.

the thing about trying this with superhuman intelligence is that if you get that wrong on the first try, you do not get to learn from your mistakes, because you are dead. Humanity does not learn from the mistake and dust itself off and try again, as in other challenges we’ve overcome in our history, because we are all gone.

If we held anything in the nascent field of Artificial General Intelligence to the lesser standards of engineering rigor that apply to a bridge meant to carry a couple of thousand cars, the entire field would be shut down tomorrow.

We are not on course to be prepared in any reasonable time window. There is no plan. Progress in AI capabilities is running vastly, vastly ahead of progress in AI alignment or even progress in understanding what the hell is going on inside those systems

Many researchers working on these systems think that we’re plunging toward a catastrophe, with more of them daring to say it in private than in public; but they think that they can’t unilaterally stop the forward plunge, that others will go on even if they personally quit their jobs.

This is a stupid state of affairs, and an undignified way for Earth to die, and the rest of humanity ought to step in at this point and help the industry solve its collective action problem.

When the insider conversation is about the grief of seeing your daughter lose her first tooth, and thinking she’s not going to get a chance to grow up, I believe we are past the point of playing political chess about a six-month moratorium.

The moratorium on new large training runs needs to be indefinite and worldwide. There can be no exceptions, including for governments or militaries. If the policy starts with the U.S., then China needs to see that the U.S. is not seeking an advantage but rather trying to prevent a horrifically dangerous technology which can have no true owner and which will kill everyone in the U.S. and in China and on Earth

Here’s what would actually need to be done:

Shut down all the large GPU clusters (the large computer farms where the most powerful AIs are refined). Shut down all the large training runs

Put a ceiling on how much computing power anyone is allowed to use in training an AI system, and move it downward over the coming years to compensate for more efficient training algorithm

Track all GPUs sold. If intelligence says that a country outside the agreement is building a GPU cluster, be less scared of a shooting conflict between nations than of the moratorium being violated; be willing to destroy a rogue datacenter by airstrike.

Frame nothing as a conflict between national interests, have it clear that anyone talking of arms races is a fool

Make it explicit in international diplomacy that preventing AI extinction scenarios is considered a priority above preventing a full nuclear exchange, and that allied nuclear countries are willing to run some risk of nuclear exchange if that’s what it takes to reduce the risk of large AI training runs.

when your policy ask is that large, the only way it goes through is if policymakers realize that if they conduct business as usual, and do what’s politically easy, that means their own kids are going to die too.

Labour’s troubles don’t end there. For months Starmer and his shadow cabinet have tied themselves in knots attempting to answer what appears to be a rather basic question: can a woman have a penis?

Starmer’s failure to articulate a simple position has put him on a collision course with feminist groups and his own MP Rosie Duffield, who has claimed that the party has a “women problem”

he says: “For 99.9 per cent of women, it is completely biological . . . and of course they haven’t got a penis.”

According to the 2021 census, 262,000 people in Britain — 0.5 per cent of the population — stated that their gender identity was different to their sex registered at birth. Of those, 48,000 — 0.1 per cent — identified as a trans woman.

Starmer says: “Look, of course I’d want to know. I say that as a parent. I would want to know and I think the vast majority of parents would want to know. That’s why we have to have national guidance on it and they should try to make it cross-party, because it’s not helpful to parents or schools to have this as just a toxic divide when what’s needed is practical, common sense advice.

He adds: “There are some people who identify as a different gender to the one they are born with. It’s a very small number and that is why the Gender Recognition Act was passed [in 2004].

“To recognise that they need legal support and a framework and most people don’t disagree with that, and that’s the framework within which we ought to look at these issues. But simply turning it into a toxic divide advances the cause of no one, the cause of women or those that don’t identify with the gender that they were born into.

And it’s also a pattern of behaviour of the last ten years which is now turning everything into a toxic culture, when it possibly can, which is the last resort of politicians who have nothing substantive to say on the issue.”

On the subject of children, Starmer, who has a son and daughter with his wife, Victoria, is also clear that there is a need for greater transparency from teachers

only 39 out of 140 English secondary schools were “reliably informing” parents when pupils identified as trans or questioned their gender.

In an attempt to win back the support of gender critical campaigners and MPs, Starmer is eager to stress that there will be “no rolling back” on women’s hard-won rights, saying: “I think there is a fear that somehow there could be the rolling back of some of the things that have been won. There are still many battles that need to go ahead for women and I don’t think we should roll anything back. I think we should go on to win the next battles for women. And that is a very important sort of starting point for this debate.”

he is clear that in order for Labour to overturn the Tories’ majority — which was a historic 80 seats at the 2019 election — it will require him to stick to his three-part plan for power: to change the party, expose the government’s failings, and have the answers to the challenges facing the country.

“You’ve got to have a race strategy. And my strategy was that you’ve got to be in the leading pack as you go round the track three and three-quarter times. But you shouldn’t hit the front too early

each time you go round the lap, there are people on the side going: go faster, pump harder . . . And what we’ve had to do over the last three years is to keep the discipline, which is that we have got a strategy, we are operating to it and there is such a determination to get us over the finishing line, which would be such an incredible achievement if we can go from the disastrous defeat of the 2019 election into power.”

Meanwhile, STEM’s conquest of the university has wrecked old humanistic homes. As Nathan Heller’s recent article in The New Yorker documented, the English department is now an unpopulated, undesired version of its former self.

That her book doesn’t feel terribly urgent perhaps speaks to a fundamental weakness within humanism.

Bakewell self-identifies as a stalwart of humanism, but even she concedes that this is an elusive label. “Humanism is personal, and it is a semantic cloud of meanings and implications, none attachable to any particular theorist or practitioner.” Without a pithy definition or clear doctrine, she can manage only to narrow humanism down to three characteristics: freethinking, hope, and inquiry

By setting aside all thoughts of the afterlife, the humanist can focus on making the most of earthly existence, pursuing happiness and mitigating suffering.

the belief that people can feel genuine solidarity for one another, despite their differences—but this is a paper-thin morality that hardly survives the skepticism that Bakewell celebrates.

she would clearly like humanism to be more substantial than it actually is. The ism suffix in Bakewell’s subject is, in fact, a bit of misdirection, because it implies a political idea or perhaps a coherent worldview

Humanism is not a synonym for liberalism or philosophical pragmatism. It more accurately describes a temperament

he humanistic canon she constructs sprawls to include the likes of David Hume, Voltaire, Thomas Paine, Frederick Douglass, John Stuart Mill, Zora Neale Hurston, and Thomas Mann.

It can sometimes be a struggle to see the commonalities, other than some degree of skepticism about religion, an underlying decency, and a general cheeriness in the midst of dreary struggles against the prevailing politics of their times.

While it’s true that freethinking is the enemy of authoritarianism, humanism suffers from a tendency to oversell itself. It doesn’t have a good track record of effectively standing up to facism,

in the current American context, right-wing ethno-nationalists have cynically draped themselves in the trappings of humanism. The likes of Ben Shapiro and Tucker Carlson present themselves as the true defenders of freethinking and open inquiry.

Self-doubt, a cheerful disposition, and a joyous pursuit of knowledge are qualities that might make for wise leaders, but can also produce hapless political combatants. Or, as Mann once declared: “In all humanism there is an element of weakness, which … may be its ruin.”

humanism is more like religion than Bakewell is prepared to admit. At its best, it is a secular faith. Its universalist spirit and open-mindedness are ethical stances. Its wishful optimism about human possibility can provide spiritual nourishment in a fallen world.

This makes it a style of dissidence well suited for the age of AI. The humanist becomes the contrarian who insists on maintaining that which automation seeks to render obsolete: the faculties of the independent mind, the very core of intellectual personhood.

Teachers are not only burnt out and undercompensated, they are also demoralized. They are being asked to do things in the name of teaching that they believe are mis-educational and harmful to students and the profession. What made this work good for them is no longer accessible. That is why we are hearing so many refrains of “I’m not leaving the profession, my profession left me.”

We find there are at least 36,000 vacant positions along with at least 163,000 positions being held by underqualified teachers, both of which are conservative estimates of the extent of teacher shortages nationally.

“The current problem of teacher shortages (I would further break this down into vacancy and under-qualification) is higher than normal.” The data, Nguyen continued, “indicate that shortages are worsening over time, particularly over the last few years

a growing gap between the pay of all college graduates and teacher salaries from 1979 to 2021, with a sharp increase in the differential since 2010

The number of qualified teachers is declining for the whole country and the vast majority of states.

Wages are essentially unchanged from 2000 to 2020 after adjusting for inflation. Teachers have about the same number of students. But, teacher accountability reforms have increased the demands on their positions.

The pandemic was very difficult for teachers. Their self-reported level of stress was about as twice as high during the pandemic compared to other working adults. Teachers had to worry both about their personal safety and deal with teaching/caring for students who are grieving lost family members.

the number of students graduating from college with bachelor’s degrees in education fell from 176,307 in 1970-71 to 104,008 in 2010-11 to 85,058 in 2019-20.

We do see that southern states (e.g., Mississippi, Alabama, Georgia and Florida) have very high vacancies and high vacancy rates.”

By 2021, teachers made $1,348, 32.9 percent less than what other graduates made, at $2,009.

These gaps play a significant role in determining the quality of teachers,

Sixty percent of teachers and 65 percent of principals reported believing that systemic racism exists. Only about 20 percent of teachers and principals reported that they believe systemic racism does not exist, and the remainder were not sure

“We find,” they write, “that teachers’ cognitive skills differ widely among nations — and that these differences matter greatly for students’ success in school. An increase of one standard deviation in teacher cognitive skills is associated with an increase of 10 to 15 percent of a standard deviation in student performance.”

teachers have lower cognitive skills, on average, in countries with greater nonteaching job opportunities for women in high-skill occupations and where teaching pays relatively less than other professions.

the scholars found that the cognitive skills of teachers in the United States fell in the middle ranks:Teachers in the United States perform worse than the average teacher sample-wide in numeracy, with a median score of 284 points out of a possible 500, compared to the sample-wide average of 292 points. In literacy, they perform slightly better than average, with a median score of 301 points compared to the sample-wide average of 295 points.

Increasing teacher numeracy skills by one standard deviation increases student performance by nearly 15 percent of a standard deviation on the PISA math test. Our estimate of the effect of increasing teacher literacy skills on students’ reading performance is slightly smaller, at 10 percent of a standard deviation.

How, then, to raise teacher skill level in the United States? Hanushek and his two colleagues have a simple answer: raise teacher pay to make it as attractive to college graduates as high-skill jobs in other fields.

policymakers will need to do more than raise teacher pay across the board to ensure positive results. They must ensure that higher salaries go to more effective teachers.

The teaching of disputed subjects in schools has compounded many of the difficulties in American education.

The researchers found that controversies over critical race theory, sex education and transgender issues — aggravated by divisive debates over responses to Covid and its aftermath — are inflicting a heavy toll on teachers and principals.

“On top of the herculean task of carrying out the essential functions of their jobs,” they write, “educators increasingly find themselves in the position of addressing contentious, politicized issues in their schools as the United States has experienced increasing political polarization.”

Teachers and principals, they add, “have been pulled in multiple directions as they try to balance and reconcile not only their own beliefs on such matters but also the beliefs of others around them, including their leaders, fellow staff, students, and students’ family members.”

These conflicting pressures take place in a climate where “emotions in response to these issues have run high within communities, resulting in the harassment of educators, bans against literature depicting diverse characters, and calls for increased parental involvement in deciding academic content.”

Forty-eight percent of principals and 40 percent of teachers reported that the intrusion of political issues and opinions in school leadership or teaching, respectively, was a job-related stressor. By comparison, only 16 percent of working adults indicated that the intrusion of political issues and opinions in their jobs was a source of job-related stress

In 1979, the average teacher weekly salary (in 2021 dollars) was $1,052, 22.9 percent less than other college graduates’, at $1,364

Nearly all Black or African American principals (92 percent) and teachers (87 percent) reported believing that systemic racism exists.

White educators working in predominantly white school systems reported substantially more pressure to deal with politically divisive issues than educators of color and those working in mostly minority schools: “Forty-one percent of white teachers and 52 percent of white teachers and principals selected the intrusion of political issues and opinions into their professions as a job-related stressor, compared with 36 percent of teachers of color and principals of color.

and opinions into their professions as a job-related stressor, compar

A 54 percent majority of teachers and principals said there “should not be legal limits on classroom conversations about racism, sexism, and other topics,” while 20 percent said there should be legislated constraint

Voters, in turn, are highly polarized on the teaching of issues impinging on race or ethnicity in public schools. The Education Next 2022 Survey asked, for example:Some people think their local public schools place too little emphasis on slavery, racism and other challenges faced by Black people in the United States. Other people think their local public schools place too much emphasis on these topics. What is your view about your local public schools?

Among Democrats, 55 percent said too little emphasis was placed on slavery, racism and other challenges faced by Black people, and 8 percent said too much.

Among Republicans, 51 said too much and 10 percent said too little.

Because of the lack of reliable national data, there is widespread disagreement among scholars of education over the scope and severity of the shortage of credentialed teachers, although there is more agreement that these problems are worse in low-income, high majority-minority school systems and in STEM and special education faculties.

Public schools increasingly are targets of conservative political groups focusing on what they term “Critical Race Theory,” as well as issues of sexuality and gender identity. These political conflicts have created a broad chilling effect that has limited opportunities for students to practice respectful dialogue on controversial topics and made it harder to address rampant misinformation.

The chilling effect also has led to marked declines in general support for teaching about race, racism, and racial and ethnic diversity.

These political conflicts, the authors wrote,have made the already hard work of public education more difficult, undermining school management, negatively impacting staff, and heightening student stress and anxiety. Several principals shared that they were reconsidering their own roles in public education in light of the rage at teachers and rage at administrators’ playing out in their communities.

State University of New York tracked trends on “four interrelated constructs: professional prestige, interest among students, preparation for entry, and job satisfaction” for 50 years, from the 1970s to the present and founda consistent and dynamic pattern across every measure: a rapid decline in the 1970s, a swift rise in the 1980s, relative stability for two decades, and a sustained drop beginning around 2010. The current state of the teaching profession is at or near its lowest levels in 50 years.

Who among the next generation of college graduates will choose to teach?

Perceptions of teacher prestige have fallen between 20 percent and 47 percent in the last decade to be at or near the lowest levels recorded over the last half century

Interest in the teaching profession among high school seniors and college freshmen has fallen 50 percent since the 1990s, and 38 percent since 2010, reaching the lowest level in the last 50 years

the proportion of college graduates that go into teaching is at a 50-year low

Teachers’ job satisfaction is also at the lowest level in five decades, with the percent of teachers who feel the stress of their job is worth it dropping from 81 percent to 42 percent in the last 15 years

The combination of these factors — declining prestige, lower pay than other professions that require a college education, increased workloads, and political and ideological pressures — is creating both intended and unintended consequences for teacher accountability reforms mandating tougher licensing rules, evaluations and skill testing.

Education policy over the past decade has focused considerable effort on improving human capital in schools through teacher accountability. These reforms, and the research upon which they drew, were based on strong assumptions about how accountability would affect who decided to become a teacher. Counter to most assumptions, our findings document how teacher accountability reduced the supply of new teacher candidates by, in part, decreasing perceived job security, satisfaction and autonomy.

The reforms, Kraft and colleagues continued, increasedthe likelihood that schools could not fill vacant teaching positions. Even more concerning, effects on unfilled vacancies were concentrated in hard-to-staff schools that often serve larger populations of low-income students and students of color

We find that evaluation reforms increased the quality of newly hired novice teachers by reducing the number of teachers that graduated from the least selective institutions

We find no evidence that evaluation reforms served to attract teachers who attended the most selective undergraduate institutions.

In other words, the economic incentives, salary structure and work-life pressures characteristic of public education employment have created a climate in which contemporary education reforms have perverse and unintended consequences that can worsen rather than alleviate the problems facing school systems.

If so, to improve the overall quality of the nation’s more than three million public schoolteachers, reformers may want to give priority to paychecks, working conditions, teacher autonomy and punishing workloads before attempting to impose higher standards, tougher evaluations and less job security.

“We’re not going to recycle our way out of this,” Mr. Weiss of ClientEarth said.

Environmental groups also say that recycling has not proved effective at the scale necessary: Only 9 percent of all plastics ever made have been recycled, according to the United Nations, with most of the rest ending up in landfills and dumps.

The company said that it reduced its plastic consumption by 12 percent from 2018 to 2021, and that it has committed to use only reusable, recyclable or compostable plastic packaging by 2025. But Danone is not on track to reach that target, according to a report by the Ellen MacArthur Foundation, which set up a voluntary program with the United Nations for big companies to address plastic pollution.

To sue Danone, the environmental groups have relied on the so-called duty of vigilance law, a groundbreaking piece of legislation that France passed in 2017. It requires large companies to take effective measures to identify and prevent human rights violations and environmental damages throughout their chain of activity.

The French duty of vigilance law, the first of its kind in Europe, has since inspired similar legislation in Germany and the Netherlands, as well as a proposed European Union directive.

There is nothing like a duty of vigilance law in the United States. The Break Free From Plastic Pollution Act, which would require plastic producers to finance waste and recycling programs, and ban single-use plastic bags and the exporting of plastic waste to developing countries, is currently in committee.

“It’s often about streamlining existing practices,” said Pauline Barraud de Lagerie, a sociologist at University Paris Dauphine who published a book on corporate responsibility. She added that by suing companies, “N.G.O.s are trying to somehow bring back an obligation of result.”So far, around 15 legal cases based on the French law have been reported. Half of them have gone to court and are still awaiting judgment, which could take years.

The lawsuit is part of a wider trend of climate litigation that has gained momentum in recent years, expanding the climate fight beyond traditional demonstrations and civil disobedience initiatives.

The number of climate change lawsuits globally has more than doubled from 2017 to 2022, from about 900 to more than 2,000 ongoing or concluded cases, according to data from the Grantham Research Institute and the Sabin Center for Climate Change Law.

Donor-advised funds are categorized by law as public charities, rather than private foundations, so they have no payout requirements and few disclosure requirements.

And wealthy residents of Silicon Valley are donating large sums to such funds

critics say that in part because of its structure as a warehouse of donor-advised funds, the Silicon Valley Community Foundation has not had a positive impact on the community it is meant to serve. Some people I talked to say the foundation has had little interest in spending money, because its chief executive, Emmett Carson, who was placed on paid administrative leave after the Chronicle’s report, wanted it to be known that he had created one of the biggest foundations in the country. Carson was “aggressive” about trying to raise money, but “unaggressive about suggesting what clients would do with it,”

“Most of us in the local area have seen our support from the foundation go down and not up,” he said.

The amount of money going from the Silicon Valley Community Foundation to the nine-county Bay Area actually dropped in 2017 by 46 percent, even as the amount of money under management grew by 64 percent, to $13.5 billion

“They got so drunk on the idea of growth that they lost track of anything smacking of mission,” he said. It did not help perceptions that the foundation opened offices in New York and San Francisco at the same time local organizations were seeing donations drop.

The foundation now gives her organization some grants, but they don’t come from the donor-advised funds, she told me. “I haven’t really cracked the code of how to access those donor-advised funds,” she said. Her organization had been getting between $50,000 and $100,000 a year from United Way that it no longer gets, she said,

Rob Reich, the co-director of the Stanford Center on Philanthropy and Civil Society, set up a donor-advised fund at the Silicon Valley Community Foundation as an experiment. He spent $5,000—the minimum amount accepted—and waited. He received almost no communication from the foundation, he told me. No emails or calls about potential nonprofits to give to, no information about whether the staff was out looking for good opportunities in the community, no data about how his money was being managed.

One year later, despite a booming stock market, his account was worth less than the $5,000 he had put in, and had not been used in any way in the community. His balance was lower because the foundation charges hefty fees to donors who keep their money there. “I was flabbergasted,” he told me. “I didn’t understand what I, as a donor, was getting for my fees.”

Though donors receive a big tax break for donating to donor-advised funds, the funds have no payout requirements, unlike private foundations, which are required to disperse 5 percent of their assets each year. With donor-advised funds, “there’s no urgency and no forced payout,”

he had met wealthy individuals who said they were setting up donor-advised funds so that their children could disperse the funds and learn about philanthropy—they had no intent to spend the money in their own lifetimes.

Fund managers also receive fees for the amount of money they have under management, which means they have little incentive to encourage people to spend the money in their accounts,

Transparency is also an issue. While foundations have to provide detailed information about where they give their money, donor-advised funds distributions are listed as gifts made from the entire charitable fund—like the Silicon Valley Community Foundation—rather than from individuals.

Donor-advised funds can also be set up anonymously, which makes it hard for nonprofits to engage with potential givers. They also don’t have websites or mission statements like private foundations do, which can make it hard for nonprofits to know what causes donors support.

Public charities—defined as organizations that receive a significant amount of their revenue from small donations—were saddled with less oversight, in part because Congress figured that their large number of donors would make sure they were spending their money well, Madoff said. But an attorney named Norman Sugarman, who represented the Jewish Community Federation of Cleveland, convinced the IRS to categorize a certain type of asset—charitable dollars placed in individually named accounts managed by a public charity—as donations to public, not private, foundations.

Donor-advised funds have been growing nationally as the amount of money made by the top 1 percent has grown: Contributions to donor-advised funds grew 15.1 percent in fiscal year 2016, according to The Chronicle of Philanthropy, while overall charitable contributions grew only 1.4 percent that year

Six of the top 10 philanthropies in the country last year, in terms of the amount of nongovernmental money raised, were donor-advised funds,

In addition, those funds with high payout rates could just be giving to another donor-advised fund, rather than to a public charity, Madoff says. One-quarter of donor-advised fund sponsors distribute less than 1 percent of their assets in a year,

Groups that administer donor-advised funds defend their payout rate, saying distributions from donor-advised funds are around 14 percent of assets a year. But that number can be misleading, because one donor-advised fund could give out all its money, while many more could give out none, skewing the data.

Donor-advised funds are especially popular in places like Silicon Valley because they provide tax advantages for donating appreciated stock, which many start-up founders have but don’t necessarily want to pay huge taxes on

Donors get a tax break for the value of the appreciated stock at the time they donate it, which can also spare them hefty capital-gains taxes. “Anybody with a business interest can give their business interest before it goes public and save huge amounts of taxes,”

Often, people give to donor-advised funds right before a public event like an initial public offering, so they can avoid the capital-gains taxes they’d otherwise have to pay, and instead receive a tax deduction. Mark Zuckerberg and Priscilla Chan gave $500 million in stock to the foundation in 2012, when Facebook held its initial public offering, and also donated $1 billion in stock in 2013

Wealthy donors can also donate real estate and deduct the value of real estate at the time of the donation—if they’d given to a private foundation, they’d only be able to deduct the donor’s basis value (typically the purchase price) of the real estate at the time they acquired it. The difference can be a huge amount of money in the hot market of California.

what worries me even more is the change I see in ordinary Americans. I live in the heart of MAGA country, and Donald Trump is the single most culturally influential person here. It’s not close. He’s far more influential than any pastor, politician, coach or celebrity. He has changed people politically and also personally. It is common for those outside the Trump movement to describe their aunts or uncles or parents or grandparents as “lost.” They mean their relatives’ lives are utterly dominated by Trump, Trump’s media and Trump’s grievances.

never before have I seen extremism penetrate a vast American community so deeply, so completely and so comprehensively.

Polling data again and again backs up the reality that the right is abandoning decency, and doing so in the most alarming of ways. It began happening almost immediately with white evangelicals

In 2011, they were the American cohort least likely to agree that a politician could commit immoral acts in private yet “still behave ethically and fulfill their duties in their public and professional life.”

They went from least likely to most likely to excuse the immoral behavior of politicians.

An increasing percentage are now tempted to embrace political violence. Last October, a startling 33 percent of Republicans (and an even larger 41 percent of pro-Trump Americans) agreed with the statement that “because things have gotten so far off track, true American patriots may have to resort to violence in order to save our country.”

That percentage is far higher than the (still troubling) 22 percent of independents and 13 percent of Democrats who shared the same view.

As the Iowa caucuses approached, Trump escalated his language, going so far as to call his political opponents “vermin” and declaring that immigrants entering America illegally are “poisoning the blood of our country.” The statement was so indefensible and repugnant that many expected it to hurt Trump. Yet a Des Moines Register/NBC News/Mediacom Iowa Poll found that a 42 percent plurality of likely Iowa Republican caucusgoers said the statement would make them more likely to support Trump — a substantially greater percentage than the 28 percent who said it would make them less likely to support him.

While political violence is hardly exclusive to the right, the hostility and vitriol embedded in MAGA America is resulting in an escalating wave of threats and acts of intimidation.

The result is a religious movement steeped in fanaticism but stripped of virtue. The fruit of the spirit described in Galatians in the New Testament — “love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control” — is absent from MAGA Christianity, replaced by the very “works of the flesh” the same passage warned against, including “hatreds, strife, jealousy, outbursts of anger, selfish ambitions, dissensions” and “factions.”

in the upside-down world of MAGA morality, vice is virtue and virtue is vice. My colleague Jane Coaston even coined a term, “vice signaling,” to describe how Trump’s core supporters convey their tribal allegiance. They’re often deliberately rude, transgressive or otherwise unpleasant, just to demonstrate how little they care about conventional moral norms.

For most of my life, conservative evangelicals (including me) have been fond of quoting John Adams’s 1798 letter to the Massachusetts Militia. It’s a critical founding document, one that forcefully argues that our Republic needs a virtuous citizenry to survive. “Our Constitution was made only for a moral and religious People,” he asserts. “It is wholly inadequate to the government of any other.”

I’ve appreciated that quote because it recognizes the obligations of a free people in a constitutional republic to exercise their liberty toward virtuous purposes.

Absent public virtue, a republic can fall. And a Trump win in 2024 would absolutely convince countless Americans that virtue is for suckers, and vice is the key to victory.

if he wins again, the equation will change and history may record that he was not the culmination of a short-lived reactionary moment, but rather the harbinger of a greater darkness to come.

The mania behind these products is heightened by their collectability and the sense of connection they offer, industry experts say.“Material things have always been markers of identity,” Drenten said.

It’s also compounded by biology — puberty and cognitive development can feel upending and confusing, said Mindy Weinstein, the founder and chief executive of digital marketing company Market MindShift. So buying into a trend or product — perhaps popularized by older teens — can ease those uncomfortable feelings.

It’s known as the “bandwagon effect, and it’s really pronounced in that age group,

“they aren’t always sure where they fit into the world. But now by buying that [item] they feel like they fit in.

Every generation of tween has had products, accessories, brands and styles they covet. A decade ago, it was Justice clothing, colorful iPod minis, Sidekick cellphones and EOS lip balm. In the early 2000s, Juicy sweatsuits, North Face fleece jackets, Nike Shox, Abercrombie & Fitch and Razr flip phones reigned. In the ’90s it was buying from the Delia’s catalogue magazine, Lip Smacker balms, United Colors of Benetton and Tommy Hilfiger polos. The ’80s had Guess jeans, Keds, banana hair clips and J. Crew sweaters. In the ’70s it was mood rings, Wrangler and Levi’s jeans, Puma sneakers and Frye boots.

More than half of U.S. teenagers (ages 13 to 19) spend at least four hours a day on social media, according to Gallup, and most of that time is spent on YouTube and TikTok

And it’s highly effective — consumers are more likely to consider buying a product and have a favorable opinion about it if it went vira

“TikTok influencers already have their trust … teens and tweens see them and they want to also be into that trend and feel like they’re belonging to that social group,

It used to be that our hair, makeup and skin care products were only visible to those who entered our bedrooms, scanning vanities and opening drawers. Now, teens and tweens are filming “Get ready with me” videos, showing off their Rare Beauty liquid blush ($23), Laneige lip balm ($18) and Charlotte Tilbury setting spray ($38) as they complain about school or recap a friend’s bat mitzvah.

Margeaux Richmond and her friends spend a lot of time talking about skin care. The 12-year-old from Des Moines said she got a $62 Drunk Elephant moisturizer for Christmas. “It’s kind of pricey, but if it’s good for your skin it’s worth it,” she said. “It’s kind of important to me and my friends because we don’t want our skin to look bad or anything.”

This also fuels a collectability culture. The customer no longer wants one water bottle, one pair of Air Jordans, one Summer Fridays lip balm or one Nike sweatshirt — they want them in every color.

“We have to think about today’s consumers, not as consumers, but as fans; and fandom has always been intertwined with collecting,” Drenten said. “In today’s culture, particularly among young people, we’ve kind of shifted away from obsession with celebrities to obsession with brands.”

Having and displaying a collection on shelves and on social media is seen as a status symbol.

Superfans also collect accessories for some of these products, Briggs said, spawning a whole side industry for some products.

Who’s doing the actual buying is harder to track. Not all adolescents have jobs or parents who are able or willing to spend $550 on Apple AirPods Max or $275 on a Tiffany & Co’s Pink Double Heart Tag Pendant necklace. “These products, to some extent, are a point of privilege and status,

Some of the spending could be attributed to more young people in the workforce: Roughly 37 percent of 16- to 19-year-olds had a job or were looking for one last year,

That’s the highest rate since 2009.

Richmond said she uses her babysitting money to buy Drunk Elephant skin care or Kendra Scott jewelry — items “my parents won’t buy me.” She’s saving up for her second Stanley tumbler.

Drenten emphasized that shopping or gift hauls on social media don’t reflect what every teen or tween wants. It varies by socioeconomics, demographics and personal preference. “At the end of the day, they can still be influenced by who they’re around and not necessarily what they’re seeing as the top line products online.”

Dr. Monteiro and his colleagues developed a food classification system called Nova, named after the Portuguese and Latin words for “new.” It has since been adopted by researchers across the world.

Unprocessed or minimally processed foods, like fresh or frozen fruits and vegetables, beans, lentils, meat, poultry, fish, eggs, milk, plain yogurt, rice, pasta, corn meal, flour, coffee, tea and herbs and spices.

Processed culinary ingredients, such as cooking oils, butter, sugar, honey, vinegar and salt.

If you look at the ingredient list and you see things that you wouldn’t use in home cooking, then that’s probably an ultraprocessed food,”

his group includes freshly baked bread, most cheeses and canned vegetables, beans and fish. These foods may contain preservatives that extend shelf life.

Ultraprocessed foods made using industrial methods and ingredients you wouldn’t typically find in grocery stores — like high-fructose corn syrup, hydrogenated oils and concentrated proteins like soy isolate.

They often contain additives like flavorings, colorings or emulsifiers to make them appear more attractive and palatable.

Think sodas and energy drinks, chips, candies, flavored yogurts, margarine, chicken nuggets, hot dogs, sausages, lunch meats, boxed macaroni and cheese, infant formulas and most packaged breads, plant milks, meat substitutes and breakfast cereals.

Processed foods made by combining foods from Category 1 with the ingredients of Category 2 and preserving or modifying them with relatively simple methods like canning, bottling, fermentation and baking

That has led to debate among nutrition experts about whether it’s useful for describing the healthfulness of a food, partly since many UPFs — like whole grain breads, flavored yogurts and infant formulas — can provide valuable nutrients

Most research linking UPFs to poor health is based on observational studies, in which researchers ask people about their diets and then track their health over many years.

Why might UPFs be harmful?

In a large review of studies that was published in 2024, scientists reported that consuming UPFs was associated with 32 health problems, with the most convincing evidence for heart disease-related deaths, Type 2 diabetes and common mental health issues like anxiety and depression.

Such studies are valuable, because they can look at large groups of people — the 2024 review included results from nearly 10 million — over the many years it can take for chronic health conditions to develop

She added that the consistency of the link between UPFs and health issues increased her confidence that there was a real problem with the foods.

But the observational studies also have limitations,

It’s true that there is a correlation between these foods and chronic diseases, she said, but that doesn’t mean that UPFs directly cause poor health.

Dr. O’Connor questioned whether it’s helpful to group such “starkly different” foods — like Twinkies and breakfast cereals — into one category. Certain types of ultraprocessed foods, like sodas and processed meats, are more clearly harmful than others

UPFs like flavored yogurts and whole grain breads, on the other hand, have been associated with a reduced risk of developing Type 2 diabetes.

Clinical trials are needed to test if UPFs directly cause health problems, Dr. O’Connor said. Only one such study, which was small and had some limitations, has been done, s

In that study, published in 2019, 20 adults with a range of body sizes lived in a research hospital at the National Institutes of Health for four weeks. For two weeks, they ate mainly unprocessed or minimally processed foods, and for another two weeks, they ate mainly UPFs. The diets had similar amounts of calories and nutrients, and the participants could eat as much as they wanted at each meal.

During their two weeks on the ultraprocessed diet, participants gained an average of two pounds and consumed about 500 calories more per day than they did on the unprocessed diet

During their time on the unprocessed diet, they lost about two pounds.

That finding might help explain the link between UPFs, obesity and other metabolic conditions

The Nova system notably doesn’t classify foods based on nutrients like fat, fiber, vitamins or minerals. It’s “agnostic to nutrition,”

There are many “strong opinions” about why ultraprocessed foods are unhealthy, Dr. Hall said. “But there’s actually not a lot of rigorous science” on what those mechanisms are

Because UPFs are often cheap, convenient and accessible, they’re probably displacing healthier foods from our diets

the foods could be having more direct effects on health. They can be easy to overeat — maybe because they contain hard-to-resist combinations of carbohydrates, sugars, fats and salt, are high-calorie and easy to chew

It’s also possible that resulting blood sugar spikes may damage arteries or ramp up inflammation, or that certain food additives or chemicals may interfere with hormones, cause a “leaky” intestine or disrupt the gut microbiome.

Researchers, including Dr. Hall and Dr. Davy, are beginning to conduct small clinical trials that will test some of these theories.

most researchers think there are various ways the foods are causing harm. “Rarely in nutrition is there a single factor that fully explains the relationship between foods and some health outcome,”

In 2014, Dr. Monteiro helped write new dietary guidelines for Brazil that advised people to avoid ultraprocessed foods.

Other countries like Mexico, Israel and Canada have also explicitly recommended avoiding or limiting UPFs or “highly processed foods.”

The U.S. dietary guidelines contain no such advice, but an advisory committee is currently looking into the evidence on how UPFs may affect weight gain, which could influence the 2025 guidelines.

It’s difficult to know what to do about UPFs in the United States, where so much food is already ultraprocessed and people with lower incomes can be especially dependent on them,

“At the end of the day, they are an important source of food, and food is food,” Dr. Mattei added. “We really cannot vilify them,”

While research continues, expert opinions differ on how people should approach UPFs.

the safest course is to avoid them altogether

to swap flavored yogurt for plain yogurt with fruit, for example, or to buy a fresh loaf from a local bakery instead of packaged bread, if you can afford to do so

Dr. Vadiveloo suggested a more moderate strategy, focusing on limiting UPFs that don’t provide valuable nutrients, like soda and cookies

She also recommended eating more fruits, vegetables, whole grains (ultraprocessed or not), legumes, nuts and seeds.

Cook at home as much as you can, using minimally processed foods

how many are aware that President Biden is among the more popular — well, less unpopular — leaders in the Western world?

First, let’s talk about some other international comparisons that seem relevant to the current situation.

But public perception of our economic performance is strongly colored by rising prices. Inflation — the rate at which prices are rising — has subsided a lot, but prices haven’t and won’t come down

No matter what we did, many people were going to die — but the death toll was affected by politics, perhaps especially by the way vaccines became a front in the culture war. And America had a really bad pandemic, even compared with its peers. U.S. life expectancy was already lagging behind comparable countries’ by 2019, but the gap widened after Covid-19 struck.

On the other hand, the U.S. economy experienced an exceptionally strong bounce back from the pandemic recession. Even after adjusting for inflation, U.S. gross domestic product per capita is up 7 percent since the eve of the pandemic, greatly exceeding growth in other major wealthy economies

This would seem on the face of it to say something good about Biden’s economic policies.

Although we hear politicians on the campaign trail trying to make hay with the old Reagan-era question — Are you better off than you were four years ago? — there’s a lot of amnesia about what was actually happening in 2020, namely a deadly, terrifying pandemic

there have been huge recriminations against policymakers, both the Biden administration and the Federal Reserve, either for supposedly causing the bout of inflation or at any rate failing to prevent it.

the similarities between the wealthiest nations are more revealing than their differences.

Inflation surged almost everywhere after the pandemic. And if you take care to compare “apples to Äpfel” — to use the same consumer price measures — inflation has been remarkably similar in different countries.

Since the eve of the pandemic, the Harmonized Index of Consumer Prices has risen 19.6 percent in the United States and 19.8 percent in the euro area.

This strongly suggests that pandemic-related disruptions, rather than national policies, were inflation’s main driver.

Still, inflation rankles voters. Even when income growth exceeds inflation, as it has in the United States, people tend to feel that they earned their higher wages only to have them snatched away by higher prices

this is probably the most important reason that, according to tracking polls conducted by Morning Consult, every single leader of a Group of 7 nation is underwater, with more voters disapproving than approving of their leadership.

So who’s the winner of this unpopularity contest? Who has the least bad net approval? The answer is Joe Biden, with Giorgia Meloni of Italy a close second. The other Group of 7 leaders are even more unpopular

this has political consequences

every political analysis that says the fault for Biden’s low approval lies with the president and his campaign — that he’s too old (although that narrative, after suddenly peaking, mostly faded away after his State of the Union address) or is out of touch with the concerns of “real” Americans — needs to explain why he’s doing less badly than his foreign peers.

It’s dropping in developing countries, too. India surpassed China as the most populous country last year, yet its fertility is now below replacement.

“The demographic winter is coming,”

Smaller populations come with diminished global clout, raising questions in the U.S., China and Russia about their long-term standings as superpowers.

Some demographers think the world’s population could start shrinking within four decades—one of the few times it’s happened in history.

A year ago Japanese Prime Minister Fumio Kishida declared that the collapse of the country’s birthrate left it “standing on the verge of whether we can continue to function as a society.”

Had fertility stayed near 2.1, where it stood in 2007, the U.S. would have welcomed an estimated 10.6 million more babies since

In 2017, when the global fertility rate—a snapshot of how many babies a woman is expected to have over her lifetime—was 2.5, the United Nations thought it would slip to 2.4 in the late 2020s. Yet by 2021, the U.N. concluded, it was already down to 2.3—close to what demographers consider the global replacement rate of about 2.2

He has found that national birth registries are typically reporting births 10% to 20% below what the U.N. projected.

China reported 9 million births last year, 16% less than projected in the U.N.’s central scenario. In the U.S., 3.59 million babies were born last year, 4% less than the U.N. projected. In other countries, the undershoot is even larger: Egypt reported 17% fewer births last year. In 2022, Kenya reported 18% fewer.

In 2017 the U.N. projected world population, then 7.6 billion, would keep climbing to 11.2 billion in 2100. By 2022 it had lowered and brought forward the peak to 10.4 billion in the 2080s. That, too, is likely out of date

the University of Washington now thinks it will peak around 9.5 billion in 2061 then start declining. 

The falling birthrates come with huge implications for the way people live, how economies grow and the standings of the world’s superpowers.

In the U.S., a short-lived pandemic baby boomlet has reversed. The total fertility rate fell to 1.62 last year, according to provisional government figures, the lowest on record.

In 2017, when the fertility rate was 1.8, the Census Bureau projected it would converge over the long run to 2.0. It has since revised that down to 1.5. “It has snuck up on us,”

Historians refer to the decline in fertility that began in the 18th century in industrializing countries as the demographic transition. As lifespans lengthened and more children survived to adulthood, the impetus for bearing more children declined. As women became better educated and joined the workforce, they delayed marriage and childbirth, resulting in fewer children. 

Some demographers see this as part of a “second demographic transition,” a societywide reorientation toward individualism that puts less emphasis on marriage and parenthood, and makes fewer or no children more acceptable. 

In research published in 2021, the University of Maryland’s Kearney and two co-authors looked for possible explanations for the continued drop. They found that state-level differences in parental abortion notification laws, unemployment, Medicaid availability, housing costs, contraceptive usage, religiosity, child-care costs and student debt could explain almost none of the decline

“We suspect that this shift reflects broad societal changes that are hard to measure or quantify,” they conclude.

while raising children is no more expensive than before, parents’ preferences and perceived constraints have changed

“If people have a preference for spending time building a career, on leisure, relationships outside the home, that’s more likely to come in conflict with childbearing.” 

Once a low fertility cycle kicks in, it effectively resets a society’s norms and is thus hard to break, said Jackson. “The fewer children you see your colleagues and peers and neighbors having, it changes the whole social climate,”

Fertility is below replacement in India even though the country is still poor and many women don’t work—factors that usually sustain fertility.

Urbanization and the internet have given even women in traditional male-dominated villages a glimpse of societies where fewer children and a higher quality of life are the norm. “People are plugged into the global culture,

mothers and fathers, especially those that are highly educated, spend more time with their children than in the past. “The intensity of parenting is a constraint,”

Sub-Saharan Africa once appeared resistant to the global slide in fertility, but that too is changing. The share of all women of reproductive age using modern contraception grew from 17% in 2012 to 23% in 2022

Jose Rimon, a professor of public health at Johns Hopkins University, credits that to a push by national leaders in Africa which, he predicted, would drive fertility down faster than the U.N. projects. 

Mae Mariyam Thomas, 38, who lives in Mumbai and runs an audio production company, said she’s opted against having children because she never felt the tug of motherhood. She sees peers struggling to meet the right person, getting married later and, in some instances, divorcing before they have kids. At least three of her friends have frozen their eggs,

Danielle Vermeer grew up third in a family of four children on Chicago’s North Side, where her neighborhood was filled with Catholics of Italian, Irish and Polish descent and half her close friends had as many siblings as her or more.

Her Italian-American father was one of four children who produced 14 grandchildren. Now her parents have five grandchildren, including Vermeer’s two children, ages 4 and 7.

The 35-year-old, who is the co-founder of a fashion thrifting app, said that before setting out to have children, she consulted dozens of other couples and her Catholic church and read at least eight books on the subject, including one by Pope Paul VI. She and her husband settled on two as the right number.“The act of bringing a child into this world is an incredible responsibility,” she said.

Perhaps no country has been trying longer than Japan. After fertility fell to 1.5 in the early 1990s, the government rolled out a succession of plans that included parental leave and subsidized child care. Fertility kept falling.

In 2005, Kuniko Inoguchi was appointed the country’s first minister responsible for gender equality and birthrate. The main obstacle, she declared, was money: People couldn’t afford to get married or have children. Japan made hospital maternity care free and introduced a stipend paid upon birth of the child. 

Japan’s fertility rate climbed from 1.26 in 2005 to 1.45 in 2015. But then it started declining again, and in 2022 was back to 1.26.

This year, Prime Minister Fumio Kishida rolled out yet another program to increase births that extends monthly allowances to all children under 18 regardless of income, free college for families with three children, and fully paid parental leave.

noguchi, now a member of parliament’s upper house, said the constraint on would-be parents is no longer money, but time. She has pressed the government and businesses to adopt a four-day workweek

If you’re a government official or manager of a big corporation, you should not worry over questions of salary now, but that in 20 years time you will have no customers, no clients, no applicants to the Self-Defense Forces.”

Hungarian Prime Minister Viktor Orban has pushed one of Europe’s most ambitious natality agendas. Last year he expanded tax benefits for mothers so that women under the age of 30 who have a child are exempt from paying personal income tax for life. That’s on top of housing and child-care subsidies as well as generous maternity leaves. 

Hungary’s fertility rate, though still well below replacement, has risen since 2010. But the Vienna Institute of Demography attributed this primarily to women delaying childbirth because of a debt crisis that hit around 2010. Adjusted for that, fertility has risen only slightly, it concluded.

The usual prescription in advanced countries is more immigration, but that has two problems.

With no reversal in birthrates in sight, the attendant economic pressures are intensifying. Since the pandemic, labor shortages have become endemic throughout developed countries. That will only worsen in coming years as the postcrisis fall in birthrates yields an ever-shrinking inflow of young workers, placing more strain on healthcare and retirement systems.

worsening demographics could make this a second consecutive “lost decade” for global economic growth.

The Institute for Health Metrics and Evaluation found little evidence that pronatalist policies lead to sustained rebounds in fertility. A woman may get pregnant sooner to capture a baby bonus, researchers say, but likely won’t have more kids over the course of her lifetime.

As more countries confront stagnant population, immigration between them is a zero-sum gam
