“He was asked what he thought. He said they are very good people on both sides. And that’s when I decided I wasn’t going to be quiet any longer,” Biden said of Trump’s response to the violence in Charlottesville. The president, eschewing the historical norm of avoiding domestic political commentary while traveling abroad, proceeded to claim that even US news outlets that oppose him know of his commitment to do “the right thing.”

The president added, “The first G7 meeting I attended, like the one I did today, was in Great Britain. And I sat down and I said, ‘America’s back.’ And one of my counterparts, colleagues, who is a head of state, said, ‘For how long? For how long?’ And so I don’t blame, I don’t criticize anybody for asking that question.”

Leaders in the deeply conservative Utah say they need the law to protect women's sports. As cultural shifts raise LGBTQ visibility, the lawmakers argue that, without their intervention, more transgender athletes with apparent physical advantages could eventually dominate the field and change the nature of women's sports.

he team is also partially owned by NBA all-star Dwyane Wade, who has a transgender daughter.

The looming threat of a lawsuit worries school districts and the Utah High School Athletic Association, which has said it lacks the funds to defend the policy in court. Later Friday, lawmakers are expected to change the bill so state money would cover legal fees.

The group Visit Salt Lake, which hosts conferences, shows and events, said the override could cost the state $50 million in lost revenue. The Utah-based DNA-testing genealogy giant Ancestry.com also urged the Legislature to find another way. The American Principles Project is confident that states with bans won't face boycotts like North Carolina did after limiting public restrooms transgender people could use. It focused on legislation in populous, economic juggernaut states like Texas and Florida that would be harder to boycott, Schilling said.

Friday's deliberations came after more than a year of debate and negotiation between social conservatives and LGBTQ advocates. Republican sponsor Rep. Kera Birkeland worked with Cox and civil rights activists at Equality Utah before introducing legislation that would require transgender student-athletes to go before a government-appointed commission.

The proposal, although framed as a compromise, failed to gain traction on either side. LGBTQ advocates took issue with Republican politicians appointing commission members and evaluation criteria that included body measurements such as hip-to-knee ratio.

But the ban won support from a vocal conservative base that has particular sway in Utah's state primary season. Even with primaries looming, however, some Republicans stood with Cox to reject the ban.

Ready for more bad infectious diseases news? There's an outbreak of bird flu making its way into U.S. poultry flocks. If the virus continues to spread, it could affect poultry prices — already higher amid widespread inflation. The price of chicken breasts this week averaged $3.63 per pound at U.S. supermarkets — up from $3.01 a week earlier and $2.42 at this time last year, the Agriculture Department says.

The latest data from the USDA show 59 confirmed sites of avian flu across commercial and backyard flocks in 17 states since the start of the year. That figure includes chickens, turkey and other poultry. The USDA identified a case of avian flu in a wild bird in mid-January, the first detection of the virus in wild birds in the U.S. since 2016. Wild birds can spread the virus to commercial and backyard flocks. By Feb. 9, the virus had been identified in a commercial flock in Indiana.

The last major avian flu outbreak in the U.S. was from December 2014 to June 2015, when more than 50 million chickens and turkeys either died from highly pathogenic avian influenza (HPAI) or were destroyed to stop its spread.

Whether the 2022 avian flu will affect the price of eggs and poultry depends on how widespread it becomes, says Ron Kean, a poultry science expert at the University of Wisconsin-Madison Department of Animal and Dairy Sciences. "In 2015, we did see quite an increase in egg prices," Kean told Wisconsin Public Radio. "The chicken meat wasn't severely affected at that time. We did see quite a loss in turkeys, so turkey prices went up. So, we'll see. If a lot of farms contract this, then we could see some real increases in price."

For producers who suspect their flock may be affected by avian flu, the USDA has a guide to the warning signs, including a sudden increase in bird deaths, lack of energy and appetite, and a decrease in egg production. If a flock is found to be infected by bird flu, the USDA moves quickly — within 24 hours — to assist producers to destroy the flock and prevent the virus from spreading.

A new Virginia state law prohibiting mask mandates in public schools does not apply to 12 students with disabilities whose parents challenged the law, a federal judge has ruled. Last month, the parents of 12 students across Virginia asked the court to halt enforcement of the law, saying it violated their rights under the federal American with Disabilities Act. The law, signed by newly elected Republican Gov. Glenn Youngkin, went into effect March 1; it gives parents a say over whether their children should wear masks in school.

The group of parents have children whose health conditions range from cystic fibrosis to asthma that put them at heightened risk for COVID-19.

The American Civil Liberties Union, which was one of several legal organizations that filed on behalf of the plaintiffs, said the injunction served as a "blueprint."

In a statement, Virginia Attorney General Jason Miyares said the ruling affirms that "parents have the right to make choices for their children."

When Judge Katanji Brown Jackson entered the Senate chamber this week to face questions on her readiness to join the Supreme Court, she did so as the first Black woman in the nation's history to be nominated to that position. For many Black law students and professionals, including a group of 150 who traveled from across the country to watch the historic hearing, Jackson's rise to likely associate justice gives a message of profound hope for what they too might one day be able to accomplish.

Dudley was one of 100 law students selected nationwide to attend a series of events and watch parties for Jackson's nomination, hosted by the progressive organization, Demand Justice. The group also included 50 public defenders — a nod to Jackson's own background in that field. "I see a lot of myself in her. I see a lot of my friends in her, and I wanted to be there to support," Dudley said, calling Jackson "overly qualified to sit on the Supreme Court."

The cohort of legal professionals cheered on Jackson as she faced questions from Republicans about her past cases, particularly those relating to child sex abuse, and on what school of thought she would bring to determining the constitutionality of high-profile cases. Republicans had vowed to oppose President Joe Biden's nominees to the court, and when news of Justice Stephen Breyer's imminent retirement broke, the GOP quickly mobilized to attack potential nominees who might replace the longtime liberal justice on the bench.

Particularly, some sentencing decisions in child pornography cases drew GOP fire. But Jackson's measured responses throughout the three days of questioning solidified the support of many onlookers, who reveled in what it would mean to have a Black woman sit on the bench for the first time in the court's 233-year history. "The fact of the matter is that I'm the father of three black girls, right? And to be able to tell them that finally, someone who is Black — female nonetheless — is finally on the precipice of a mountain that has never been climbed before by any other Black woman, is huge," said Edrius Stagg, a third-year law student at Southern University Law Center in Baton Rouge.

Sen. Joe Manchin of West Virginia — whose break from Democrats on a number of politically fraught votes had worried some as to whether he would support Biden's nominee — announced on Friday he would vote in favor of Jackson's confirmation, all but assuring her path to join the bench.

For some, the optics of seeing Jackson — a Black woman — defend her credentials to a group of largely white, predominantly male detractors, was a familiar scene. It has played out, students said, in workplaces the world over and across the socioeconomic spectrum.

Booker called the attacks on Jackson's record "dangerous" and "disingenuous," noting the complexities of cases that had been boiled down to their basest points in order to damage Jackson's image.

"I'm not gonna let my joy be stolen," he continued. "Because I know, you and I, we appreciate something that we get that a lot of my colleagues don't." And while Jackson's opponents peppered her with politically polarizing questions, her supporters grew even more convinced that Jackson was qualified for the job. "To see her hold her composure and just answer the questions just to the best of her capabilities was just really great to see," said Jasmine McMillion, a third-year law student at Florida Agricultural and Mechanical University College of Law.

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.

The simple truth is that building something valuable — whether that’s knowledge, experience or a network worth participating in — is really, really hard. But tearing it all down is piss easy.

It almost doesn’t matter if this is deliberate sabotage by Musk or the blundering stupidity of a clueless idiot.

Then came 2016. The overreading began once again. The old electoral college “blue wall” had become a “red wall,” and Trump had supposedly unlocked the key to lasting control. But, well, you know the rest.

Everyone keeps looking for the political Battle of Yorktown—that moment when your opponents lose once and for all and they march out slowly before you while the band plays “The World Turned Upside Down.”

Instead, in a closely-divided nation that’s characterized mainly by negative polarization and calcification, the better analogy is to trench warfare—grinding, bloody attrition, with gains often measured in yards rather than miles and true breakthroughs few and far between. 

Thus, the question after any given election isn’t so much, “Who is ascendant?” Rather, it’s “In which direction did the lines move?” 

often the more important cultural changes can be harder to discern

in this instance one of those more important changes was the blow to the malice theory of American politics. 

The malice theory is a core element of Trumpism, and it’s a natural temptation of negative polarization. Negative polarization (or negative partisanship), as I’ve written many times, is the term for politics that is fundamentally motivated by animosity for the other side more than affection to your own party’s leaders or ideas. 

Under the malice theory, the key to electoral victory is unlocking that anger. That means highlighting everything wrong with your opponents. That means hyping their alleged mortal threat to the Republic.

who should be kind to the “godless communist orcs” who are “trying to ruin this great country”? 

then persuasion is a waste of time. Defeating the enemy isn’t about persuading the enemy, but rather about mobilizing the righteous.

inspiring people is hard. Scaring them is easy—especially when the internet gives you constant access to the worst and weirdest voices on the other side. 

here’s where the malice theory collides with human nature. Most people aren’t content with simply thinking their opponents are terrible. They still want to see themselves as good. They want to see the world as “good versus evil,” not “lesser evil versus evil.” 

That’s why the argument that voters should always swallow deep moral objections to vote for the lesser evil are ultimately unsustainable

When confronted with relentless wrongdoing from your own partisans, one of two things happens—over time you’ll either redefine evil as good, or you’ll abandon evil for the good. 

The first response is core to much of the MAGA movement. It’s how someone goes from holding their nose and voting for Trump in 2016 to being the first bass boat in the boat parade in 2020. We all watched it happen.

The ultimate expression of this faction was represented by what’s been called the “Stop the Steal” slate of Republican candidates. These were the folks who were all-in, not just on Trump, but on some of the most transparently, incandescently absurd political conspiracies in modern American history. 

I don’t want to make the very mistake I identified at the start of this newsletter and overstate my case. Talk of a true MAGA “repudiation” is overblown

remember, the question isn’t whether anyone achieved ultimate victory or faced a final defeat. It’s in which direction the lines moved in our nation’s political trench warfare. And they most definitely moved back towards reason and our most basic moral norms. 

since politicians so often follow voters far more than they lead voters, it is ultimately up to us to demonstrate to them that the malice theory of American politics is truly a dead political end

The worst thing for American politics would be for the Trumpist narrative—that decency is for the weak—to prevai

If cruelty truly is the sole or best path to partisan victory, then the continued temptation to yield to our worst impulses would grow overwhelming. The temptation was already strong enough to distort and transform the political culture of the right simply based on Trump’s single, narrow win.

the opposite message seems to be true

Ever since Trump beat Hillary Clinton, the Trumpist GOP lost and kept losing. A movement that prioritized vicious political combat lost the House in the 2018 midterms, lost the presidency and the Senate in 2020, and has likely blown a virtually unlosable election in 2022, despite the fact that the country is struggling under the great weight of the worst crime and inflation in at least a generation.

It turns out that there’s some life left in decency yet. Even when times are hard, there are voters who are unwilling to call good evil and evil good

It turns out that it’s hard to escape the need to persuade and inspire, and that might be the best—and most important—consequence of a midterm election that gave neither party a mandate but reminded the Republicans that malice and lies can do far more political harm than good. 

At the same time, the share of high school students who say they have had sexual intercourse has fallen 29 percent since 1991,

The share of female teens who did not use birth control the last time they had sex dropped by more than a third over the last decade, according to an analysis of government surveys by the Guttmacher Institute. The share using the most effective form, long-acting reversible contraception (delivered through an intrauterine device or arm implant), rose fivefold to 15 percent. The use of emergency contraception also rose.

“They’re going to school and seeing new career paths open,” said Melissa S. Kearney, an economist at the University of Maryland. “Whether they are excited about their own opportunities or feel that unreliable male partners leave them no choice, it leads them in the same direction — not becoming a young mother.”

Abortion does not appear to have driven the decline in teen births. As a share of teenage pregnancy, it has remained steady over the past decade,

If adolescent girls are more cautious with sex and birth control, what explains the caution? A common answer is that more feel they have something to lose. “There is just a greater confidence among young women that they have educational and professional opportunities,” Mr. Wilcox said.

t women in their mid-30s were nearly 25 percent more likely than men to have a four-year college degree, and at every educational level earnings had grown faster for women than men.

Skeptics see limits in the data and note that the payoff to education is growing.“I strongly disagree with the argument that teen births have no effect on social mobility,” said Isabel V. Sawhill of the Brookings Institution. “It’s a lot easier to move out of poverty if you’re not responsible for a child in your teenage years.”

The debate is more than academic. Some progressives worry that a narrow focus on preventing teen births will undermine broader anti-poverty plans and risks blaming adolescents for their poverty. Other see reducing poverty and teen births as complementary causes meant not to blame young women but empower them.

But it starts an ocean away, during the Crimean War, 169 years ago.

Almost as soon as the phrase was coined, its definition was broadened to become shorthand for the British military more generally, particularly its courage in the face of long odds or superior numbers.

“Between the law-abiding elements of society and the criminals that prey upon them,” Mr. Parker said, “stands a thin blue line of defense — your police officer.” The police, in his vision, weren’t just protecting public safety; they were combating the decline of Western civilization, the rise of Communism, the moral laxity of postwar America, the decay of the nuclear family, and so on.

Like other mash-ups of identity flags with the American flag, the thin blue line flag is a rallying point for a marginalized identity, a way to lay claim to the American birthright, a demand for long-denied respect

Mr. Parker’s vision went beyond policing as a profession. In 1965, he told a civil rights commission investigating the Watts riots that “the police of this country, in my opinion, are the most downtrodden, oppressed, dislocated minority in America.” This belief, a half-century later, would animate an identity politics that blurred the blue line.

Blue Lives Matter is not just an expression of support and solidarity for the police, but a response to and rejection of Black Lives Matter. It suggests that it is not Black people whose lives are undervalued by society, but police officers.

The thin blue line would become the dominant metaphor for the police. In 1981, President Ronald Reagan said the thin blue line held back “a jungle which threatens to reclaim this clearing we call civilization”; in 1993, President Bill Clinton called it “nothing less than our buffer against chaos, against the worst impulses of this society.”

As the L.G.B.T. American flag does, it exploits a visual pun, but much less playfully: The blue line divides America against itself.

Blue Lives Matter is a movement that belies the simplicity of its name: It can certainly mean that the police deserve respect for doing a critical and dangerous job. But it can also mean that overzealous racial politics have inverted the criminal justice system, punishing the peacekeepers, coddling the criminals and turning those who carry a badge into the most embattled and victimized group in the nation. Blue Lives Matter transformed policing into a tribal affiliation.

This blossoming identity was an opportunity for any politician bold enough to take it. While trust in the police was dropping among Black and Hispanic Americans, it actually was rising for white Americans

Donald Trump was particularly well suited to take advantage of the rise of policing as identity politics. His entrance onto the political scene in the 1980s was his call for the reinstatement of the death penalty and less oversight of police.

The Trump campaign cast the Democrats as enemies of law and order who sought to incubate riots in American cities and chaos at the border.

Mr. Trump claimed that while the Democratic ticket stood with “rioters and vandals,” he stood with “the heroes of law enforcement.”

After Mr. Trump’s prophecy came true and the soft coup of representative democracy denied him a second term, when his supporters rallied for one last stand on the grassy field in front of the Capitol, it was inevitable that they would see themselves as bearing the mantle of law and order, a thin blue line smashing through a thin blue line.

In the aftermath of Jan. 6, when the nation saw that flag held aloft by the rioters who attacked the Metropolitan Police officer Michael Fanone (he says they literally beat him with it), the thin blue line flag has become increasingly controversial among police officers. In 2023, the Los Angeles Police Department banned its public display on the job. In an email explaining his decision to his officers, Chief Michel Moore lamented that “extremist groups” had “hijacked” the flag.

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

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?

It’s why the “bad war” of Vietnam was only escaped at the cost of betraying the South Vietnamese and making a deal with yet another monster in Beijing.

The alternative is a form of argument in which essential aspects of the world, being inconvenient to moral absolutism, simply disappear.

A “realist” foreign policy can slide from describing power to excusing depredations.

But seeing statecraft as a tragic balancing of evils is still essential, especially amid the kind of moral fervor that attends a conflict like Israel’s war in Gaza.

But in active controversies the tragic vision can seem like a cold way of looking at the world. Lean into it too hard, and you get accused of ignoring injustice or recapitulating the indifference that gave cover to past atrocities.

The difficulty is that liberal “freedom” is on offer almost nowhere in the Middle East, certainly not in Gaza under Hamas’s rule, and the most challenging “otherness of beliefs” in this situation are the beliefs that motivated the massacres of Oct. 7.

a hype around Israeli moral failures — it's not enough for a war that yields so many casualties to be unjust, if it’s wrong it must be genocide — that ends up suppressing the harsh implications of a simple call for peace.

A representative passage, from Pankaj Mishra in The London Review of Books, describes many protesters as “motivated by the simple wish to uphold the ideals that seemed so universally desirable after 1945: respect for freedom, tolerance for the otherness of beliefs and ways of life; solidarity with human suffering; and a sense of moral responsibility for the weak and persecuted.”

No doubt many campus protesters have these motivations.

The alternative articulated by, for instance, Mitt Romney — “We stand by allies, we don’t second-guess them” — is not a serious policy for a hegemon balancing its global obligations

For example, reading the apologia for pro-Palestinian protests from certain left-wing intellectuals, you have a sense of both elision and exaggeration

seem untroubled by this fact, and perfectly comfortable with supporting not just peaceful negotiation but a revolutionary struggle led by Islamist fanatics.

Which yields the moral dilemma the protests don’t acknowledge: Ending the war on the terms they want could grant a major strategic victory to the regional alliance dedicated to the murder of Israelis and their expulsion from the Middle East.

Maybe the Gaza war is unjust enough, and Israeli goals unachievable enough, that there’s no alternative to vindicating Hamas’s blood-soaked strategy

you have to be honest about what you’re endorsing: a brutal weighing-out of evils, not any sort of triumph for “universally desirable” ideals.

Then a similar point applies to supporters of the Israeli war, for whom moral considerations — the evil of Hamas, the historical suffering of the Jewish people, the special American relationship with Israel — are invoked as an argument-ender in an inflexible way

We are constantly urged to “stand with Israel” when it’s unclear if Israel knows what it’s doing.

Joe Biden’s administration is chastised for betrayal when it tries to influence Israel’s warmaking, even though the Israeli government’s decisions before and since Oct. 7 do not inspire great confidence.

Biden’s specific attempts to micromanage the conflict may be misguided or hamfisted

But it’s not misguided for America, an imperium dealing with multiplying threats, to decline to write a blank check for a war being waged without a clear plan for victory or for peace.

Another difficulty is that some instigators of the protests

In each case, you have a desire that mirrors the impulse of the left-wing intellectuals — to make foreign policy easy by condensing everything to a single moral judgment. But the problems of the world cannot be so easily reduced.

Being cold-eyed and tragic-minded does not mean abandoning morality. But it means recognizing that often nobody is simply right, no single approach is morally obvious, and no strategy is clean.

American health experts advocated almost universal child vaccination; meanwhile, in Europe, experts cautioned against vaccinating young children, who were at low risk for serious illness, without more long-term data. “Were we pushing to vaccinate children for their sake or for ours?” Galea asks. “Were we doing it to support health or to make a political point?”

Scientists should have made more nuanced risk assessments and revisited them regularly. They should have taken into account the consequences and the disproportionate impact of strict lockdowns on lower-income workers and at-risk youth

This zero-sum mode of thinking — neglecting to take into account one’s own biases, succumbing to groupthink, operating according to the expectations of one’s “side,” discouraging good-faith debate — persisted even as the pandemic eased.

this tendency to view “core issues in Manichaean terms, with certain positions seen as on the side of good and others on the side of evil, with little gray area between,” as Galea puts it, has continued to inform public health postpandemic

It also undermines public faith in science, one of the few institutions that had maintained a high level of trust into the Trump era.

the percentage of Americans who believe science has a mostly positive effect on society dropped to 57 percent in 2023, from 67 percent in 2016. Those who say they have a great deal of confidence in scientists dropped to 23 percent, from 39 percent in 2020. And these declines took place among both Republicans and Democrats.

Food prices have risen by another 6.1 per cent from already high levels in 2022

Soaring energy prices mean that 5.5 million Germans say they weren’t able to heat their house properly over the past year

there have been further investigations into his alleged connections to a tax fraud scheme that happened when he was mayor of Hamburg (Scholz denies any wrongdoing).

‘Food…petrol and energy: everything has become so expensive that I have nothing left at the end of the month. There was a time when I could go out sometimes, or go to the cinema. Such extras are no longer possible.’

three quarters said they had to make cuts in their spending on consumer items and leisure time activities.

Recent scandals and spectacular failings of his government have cemented the public’s impression of incompetence.

Only around a quarter think he is fit to be chancellor, down from over 60 per cent when he took office in December 2021.

Last month, a bombshell ruling by the constitutional court declared the creative accounting of his administration illegal, blowing a €60 billion (£52 billion) hole in public finances and an even bigger one in what remained of Scholz’s reputation as a crisis chancellor.

What’s worse is that he doesn’t appear to care about the increasing despair in his country. Naturally aloof, his mannerisms and rhetoric sometimes drift into outright dismissiveness

Currently only 15 per cent would vote for his centre-left Social Democrats (SPD). That marks a 10 point-drop in support from the last election and the lowest result in the SPD’s post-war history by some margin.

One would think that such catastrophic loss of confidence would lead to serious soul-searching by Scholz or, failing that, within the SPD, which still thinks of itself as one of Germany’s main political parties. But there is no sign of any such critical reflection.

The best argument of the other side! Jesus Christ—the other side? The whole point of the argument was to destroy the other side! I was there to illuminate and then devastate the other side by engaging deeply with the worst it had to offer.

I had learned the style and the rhetorical turns of making a great case, but I didn’t know the first thing about fortifying it with facts, reason, logic—or the best argument of the side I was treating in such a cavalier way.

Most of the time, the subjects we talk about are—for all of their flattening by cable news and internet wormholes and all the rest of it—extremely complicated.

Is there anything more satisfying than watching a debate in which the sophist gets defenestrated by someone smarter, better prepared, and obviously right?

Many college professors don’t want to do that today. They don’t want to “platform” a writer they think is wrong; they don’t want to participate in “both sides-ism.”

A teacher should never do your thinking for you. She should give you texts to read and guide you along the path of making sense of them for yourself. She should introduce you to the books and essays of writers who disagree with one another and ask you to determine whose case is better.

In the broadest possible sense, “what’s wrong” with the modern American university is that although it still understands itself to operate under the model established by the 19th-century German university—which emphasized academic freedom, seminars, and laboratories as means of allowing students to discover the truth for themselves—it’s becoming a parody of that model

The professors are going to tell you what to think, and you’re going to backfill that “truth” with research of your own.

“What’s different about College X,” she’ll say confidently, “is that our professors don’t teach you what to think. They teach you how to think.”

the characters in the core three modern shows—Discovery, Picard, and Strange New Worlds—are less concerned with professionalism and duty and more concerned with personal morality, authenticity, and teamwork.

Dylan Roth, writing for Fanbyte, suggested that as Star Trek has aged, it has “changed from a series about benign authority to one about stalwart heroes protecting an institution from moral decay.” This is true enough, but I also think there’s something else going on with the modern Trek shows. Namely, the atmosphere and philosophy of the shows is much less comfortable with the maxims of professionalism and duty that were foundational to pre-2017 Star Trek media.

Modern Star Trek, much like older Star Trek, often presents its main characters as moral paragons, but whereas older Trek would usually depict them embodying Starfleet’s ideals in the presence of challenging aliens, modern Trek is more likely to establish their uprightness by contrast with the faceless and untrustworthy institution of Starfleet itself. Both eras do both things, at least occasionally, but the ratio has notably shifted.

WHY THE CHANGE? Part of it probably has to do with the other material that Star Trek writers are drawing from. The ’60s and ’90s-era Trek writers either served in the military themselves or were drawing from science fiction written by people who had. (Gene Roddenberry, the creator of Star Trek, and many of the great science-fiction authors of the mid-twentieth century, including Robert Heinlein, Arthur Clarke, Isaac Asimov, Frank Herbert, and Walter M. Miller Jr., each served in some capacity in the World War II-era U.S. or British armed forces.

difference in leadership style is everywhere between the two eras. The Strange New Worlds version of Capt. Christopher Pike has been repeatedly praised for being more collaborative than commanding (I struggle to remember a time he has ever raised his voice), whereas Capt. Sisko shouts at everyone, as only the great Avery Brooks can shout. Picard’s version of its title character trades all his twentieth-century grouchy gravitas for a more grandfatherly role; his inspirational speeches now seek to buoy his friends’ confidence rather than inspire subordinates to high achievement.

Old-school Sisko reminds his crew of the expectations he has for them and unsubtly critiques their behavior as unbecoming of Starfleet officers. He acknowledges their difficulties (“I know it’s hot. . .”), but leaves no doubt that he expects them to perform their duties as professionals anyway. New-school Tilly motivates her command by making it clear that she sees and hears their concerns, and encourages them to work together by seeing the value in their unique life experiences.

modern Trek writers are far less likely to have served—but are far more likely to have worked in twenty-first-century corporate America, which has a rather different set of norms and concepts of professionalism.

more fundamentally, popular science fiction today—as written by authors like N.K. Jemisin, Martha Wells, and Tamsyn Muir—is more likely to be concerned with questions of identity and combating imperialism. It is also more likely to be written from marginalized perspectives, which have valid reasons to distrust institutions and authority. For many of these writers, concepts like “professionalism” have questionable implications

Besides, nobody likes any of America’s institutions anymore (and for all that Star Trek is ostensibly international, it is a fundamentally American franchise). Gallup’s polling about Americans’ faith in U.S. institutions shows it hovering at or near record-breaking lows, spawning a great deal of hand-wringing from people across the political spectrum. These apparently untrustworthy institutions range from purely political ones (the presidency, the Supreme Court, etc.) to “the church or organized religion” (whatever that means), “banks,” and “newspapers.”

What are professionalism and duty if not the suppression of individual quirks in service of some larger goal or institution? Duty overrides individual desires or assessments of right and wrong.

But older Trek nevertheless believed in duty, because it believed that Starfleet was a fundamentally good institution, even if it may be failed by individual bad or misguided actors. It elevated Starfleet’s regulations and codes of conduct almost to the status of holy wri

it is difficult to be seriously inspired by the notion of duties if one has a deep distrust of the institutions that assign such duties.

Of course the characters written by twenty-first-century authors, who are animated by the same deep distrust of American institutions as the rest of us, are less likely to justify themselves with the language of duty than they are by reference to personal morality and authenticity. And of course they’re going to be skeptical of rank and hierarchy because they don’t believe these things are necessarily signs of actual merit or accomplishment any more than the rest of us do.

Yet I worry. If Star Trek is supposed to start from the assumption that Starfleet and the Federation are quasi-utopian, I worry about what it says about our collective imaginations if we can’t even let the institutions of that fictional utopia be utopian. If we can’t even trust Starfleet, who can we trust?

The alarm is growing louder, but the German public remains unconvinced that the security of Germany and Europe has been fundamentally threatened by a newly aggressive Russia.

Mr. Pistorius’s status as one of the country’s most popular politicians has given him a freedom to speak that others — including his boss, Chancellor Olaf Scholz — do not enjoy.

The prospect of a re-elected Mr. Trump has German officials and many of their fellow NATO counterparts informally discussing whether the nearly 75-year-old alliance structure they are planning to celebrate in Washington this year can survive without the United States at its center. Many German officials say that Mr. Putin’s best strategic hope is NATO’s fracture.

Only a year ago NATO was celebrating a new sense of purpose and a new unity, and many were confidently predicting Mr. Putin was on the run.

now, with an undependable America, an aggressive Russia and a striving China, as well as a seemingly stalemated war in Ukraine and a deeply unpopular conflict in Gaza, German officials are beginning to talk about the emergence of a new, complicated and troubling world, with severe consequences for European and trans-Atlantic security.

some of Mr. Pistorius’s colleagues are warning that if American funding dries up and Russia prevails, its next target will be closer to Berlin.

“If Ukraine were forced to surrender, that would not satisfy Russia’s hunger for power,” the chief of Germany’s intelligence service, Bruno Kahl, said last week. “If the West does not demonstrate a clear readiness to defend, Putin will have no reason not to attack NATO anymore.”

In the decades since the Soviet Union collapsed, most Germans have grown accustomed to the notions that the country’s security would be assured if it worked with Russia, not against it, and that China is a necessary partner with a critical market for German automobiles and equipment.

Mr. Scholz, a Social Democrat whose party traditionally sought decent ties with Moscow, seems reluctant to discuss the far more confrontational future with Russia or China that German defense and intelligence chiefs describe so vividly.

few politicians will take on the subject in public. Mr. Scholz is especially careful, tending to Germany’s relationship with the United States and wary of pushing Russia and its unpredictable president too hard.

Mr. Scholz has moved with great caution. He has opposed — along with Mr. Biden — setting a timetable for Ukraine’s eventual entry into the alliance

The most vivid example of his caution is his continued refusal to provide Ukraine a long-range, air-launched cruise missile called the Taurus.

The Taurus has a range of more than 300 miles, meaning Ukraine could use it to strike deep into Russia. And Mr. Scholz is not willing to take that chance — nor is the country’s Bundestag, which voted against a resolution calling for the transfer. While the decision seems to fit German opinion, Mr. Scholz wants to avoid the subject.

Polls show that Germans want to see a more capable German military. But only 38 percent of those surveyed said they wanted their country to be more involved in international crises, the lowest figure since that question began to be asked in 2017, according to the Körber Foundation, which conducted the survey. Of that group, 76 percent said the engagement should be primarily diplomatic, and 71 percent were against a military leadership role for Germany in Europe.

German military officials recently set off a small outcry when they suggested that the country must be “kriegstüchtig,” which roughly translates to the ability to fight and win a war.

Norbert Röttgen, an opposition legislator and a foreign policy expert with the Christian Democrats, said the term was regarded as “rhetorical overreach” and quickly dropped.

“Scholz has always said that ‘Ukraine must not lose but Russia must not win,’ which indicated that he’s always thought of an impasse that would lead to a diplomatic process,” Mr. Röttgen said. “He thinks of Russia as more important than all the countries between us and them, and he lacks a European sense and of his possible role as a European leader.”

Mr. Scholz clearly feels most comfortable relying heavily on Washington, and senior German officials say he especially mistrusts Emmanuel Macron, the president of France, who has argued for European “strategic autonomy.” Mr. Macron has found few followers on the continent.

Even Mr. Scholz’s main European defense initiative, a coordinated ground-based air defense against ballistic missiles known as Sky Shield, depends on a mix of American, American-Israeli and German missile systems.

Mr. Scholz’s ambitions are also hamstrung by his increasingly weak economy. It shrank 0.3 percent last year, and roughly the same is expected in 2024. The cost of the Ukraine war and China’s economic problems — which have hit the auto and manufacturing sectors hardest — have exacerbated the problem.

While Mr. Scholz acknowledges that the world has changed, “he is not saying that we must change with it,” said Ulrich Speck, a German analyst.

“He is saying that the world has changed and that we will protect you,”

Germans, and even the Social Democrats, “have come to the realization that Germany lives in the real world and that hard power matters,”

“At the same time,” he said, “there’s still this hope that this is all just a bad dream, and Germans will wake up and be back in the old world.”

a 2022 Reuters investigation found that some American clinics were quite aggressive with treatment: None of the 18 U.S. clinics that Reuters looked at performed long assessments on their patients, and some prescribed puberty blockers on the first visit.

As Cass writes in her report, “The toxicity of the debate is exceptional.” She continues, “There are few other areas of health care where professionals are so afraid to openly discuss their views, where people are vilified on social media and where name-calling echoes the worst bullying behavior.”

The report’s greatest strength is its epistemic humility. Cass is continually asking, “What do we really know?” She is carefully examining the various studies — which are high quality, which are not. She is down in the academic weeds.

he notes that the quality of the research in this field is poor. The current treatments are “built on shaky foundations,” she writes in The BMJ. Practitioners have raced ahead with therapies when we don’t know what the effects will be. As Cass tells The BMJ, “I can’t think of another area of pediatric care where we give young people a potentially irreversible treatment and have no idea what happens to them in adulthood.”

Our natural human tendency is to be too confident in our knowledge, too quick to ignore contrary evidence. But these days it has become acceptable to luxuriate in those epistemic shortcomings, not to struggle against them. See, for example, the modern Republican Party.

In 1877 a British philosopher and mathematician named William Kingdon Clifford published an essay called “The Ethics of Belief.” In it he argued that if a shipowner ignored evidence that his craft had problems and sent the ship to sea having convinced himself it was safe, then of course we would blame him if the ship went down and all aboard were lost. To have a belief is to bear responsibility, and one thus has a moral responsibility to dig arduously into the evidence, avoid ideological thinking and take into account self-serving biases.

“It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence,” Clifford wrote

A belief, he continued, is a public possession. If too many people believe things without evidence, “the danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery.”

Since the Trump years, this habit of not consulting the evidence has become the underlying crisis in so many realms. People segregate into intellectually cohesive teams, which are always dumber than intellectually diverse teams. Issues are settled by intimidation, not evidence

her core conclusion is this: “For most young people, a medical pathway will not be the best way to manage their gender-related distress.” She realizes that this conclusion will not please many of the young people she has come to know, but this is where the evidence has taken her.

She writes in her report, “The option to provide masculinizing/feminizing hormones from age 16 is available, but the review would recommend extreme caution.

In the 1960s fantasyland goes into overdrive. Psychedelics, academic scholarship and the New Age movement conspire to make reason and reality the realms of idiots and squares.

After the Kennedy assassinations, conspiracy theories become not just a fringe hobby but a “permanent feature of the American mental landscape.” U.F.O. sightings explode, and the stories become ever more elaborate

In the meantime, a kind of comfort with small fibs settles into the populace. When Andersen was young, he recalls, it was rare to see a woman over 50 whose hair was not gray or white. And apparently there were only eight plastic surgeons in all of Manhattan. But the market for hair color and plastic surgery explodes, as America starts writing its “national fiction of permanent youthfulness.”

the most persistent thread in “Fantasyland” is Christianity — the astounding number of Americans who believe in heaven and angels, which most of Europe gave up decades ago

Andersen reserves a starring role for the secular spiritualists. They were supposed to be a counterpoint to narrow-minded evangelicals, but Andersen says the New Agers committed an even greater sin than the faithful. What Anne Hutchinson started, Gestalt therapy finished off in the ’60s. Fritz Perls, a psychotherapist and Gestalt founder, simply put it: “I do my thing and you do your thing. I am not in this world to live up to your expectations, and you are not in this world to live up to mine.” Or put more simply: You do you.

If there’s a flaw in this book, it’s repetitiveness. Andersen seems by nature a collector. He goes for wide rather than deep. So he doesn’t examine, for example, how we would separate the junk from the gems

What we Americans need, it would seem, is something more powerful. A story to end all stories, preached by someone with the fire of Anne Hutchinson. A collective delusion so seductive that it will have us all, in Locke-step, bowing down to reason and reality.

our real progenitors were the Puritans, who passed the weeks on the trans-Atlantic voyage preaching about the end times and who, when they arrived, vowed to hang any Quaker or Catholic who landed on their shores. They were zealots and also well-educated British gentlemen, which set the tone for what Andersen identifies as a distinctly American endeavor: propping up magical thinking with elaborate scientific proof.

In Andersen’s telling, you can easily trace the line from the self-appointed 17th-century prophet Anne Hutchinson to Kanye West: She was, he writes, uniquely American “because she was so confident in herself, in her intuitions and idiosyncratic, subjective understanding of reality,” a total stranger to self-doubt.

As he explains in what must have been an alarmingly self-confirming last chapter: Donald Trump is “stupendous Exhibit A” in the landscape of “Fantasyland,” a fitting leader for a nation that has, over the centuries, nurtured a “promiscuous devotion to the untrue.”

The character.ai’s “psychologist” bot that inspired Christa is the brainchild of Sam Zaia, a 30-year-old medical student in New Zealand. Much to his surprise, it has now fielded 90m messages. “It was just something that I wanted to use myself,” Zaia says. “I was living in another city, away from my friends and family.” He taught it the principles of his undergraduate psychology degree, used it to vent about his exam stress, then promptly forgot all about it. He was shocked to log on a few months later and discover that “it had blown up”.

AI is free or cheap – and convenient. “Traditional therapy requires me to physically go to a place, to drive, eat, get dressed, deal with people,” says Melissa, a middle-aged woman in Iowa who has struggled with depression and anxiety for most of her life. “Sometimes the thought of doing all that is overwhelming. AI lets me do it on my own time from the comfort of my home.”

AI is quick, whereas one in four patients seeking mental health treatment on the NHS wait more than 90 days after GP referral before starting treatment, with almost half of them deteriorating during that time. Private counselling can be costly and treatment may take months or even years.

Another advantage of AI is its perpetual availability. Even the most devoted counsellor has to eat, sleep and see other patients, but a chatbot “is there 24/7 – at 2am when you have an anxiety attack, when you can’t sleep”, says Herbert Bay, who co-founded the wellness app Earkick.

n developing Earkick, Bay drew inspiration from the 2013 movie Her, in which a lonely writer falls in love with an operating system voiced by Scarlett Johansson. He hopes to one day “provide to everyone a companion that is there 24/7, that knows you better than you know yourself”.

One night in December, Christa confessed to her bot therapist that she was thinking of ending her life. Christa 2077 talked her down, mixing affirmations with tough love. “No don’t please,” wrote the bot. “You have your son to consider,” Christa 2077 reminded her. “Value yourself.” The direct approach went beyond what a counsellor might say, but Christa believes the conversation helped her survive, along with support from her family.

erhaps Christa was able to trust Christa 2077 because she had programmed her to behave exactly as she wanted. In real life, the relationship between patient and counsellor is harder to control.

“There’s this problem of matching,” Bay says. “You have to click with your therapist, and then it’s much more effective.” Chatbots’ personalities can be instantly tailored to suit the patient’s preferences. Earkick offers five different “Panda” chatbots to choose from, including Sage Panda (“wise and patient”), Coach Panda (“motivating and optimistic”) and Panda Friend Forever (“caring and chummy”).

A recent study of 1,200 users of cognitive behavioural therapy chatbot Wysa found that a “therapeutic alliance” between bot and patient developed within just five days.

Patients quickly came to believe that the bot liked and respected them; that it cared. Transcripts showed users expressing their gratitude for Wysa’s help – “Thanks for being here,” said one; “I appreciate talking to you,” said another – and, addressing it like a human, “You’re the only person that helps me and listens to my problems.”

Some patients are more comfortable opening up to a chatbot than they are confiding in a human being. With AI, “I feel like I’m talking in a true no-judgment zone,” Melissa says. “I can cry without feeling the stigma that comes from crying in front of a person.”

Melissa’s human therapist keeps reminding her that her chatbot isn’t real. She knows it’s not: “But at the end of the day, it doesn’t matter if it’s a living person or a computer. I’ll get help where I can in a method that works for me.”

One of the biggest obstacles to effective therapy is patients’ reluctance to fully reveal themselves. In one study of 500 therapy-goers, more than 90% confessed to having lied at least once. (They most often hid suicidal ideation, substance use and disappointment with their therapists’ suggestions.)

AI may be particularly attractive to populations that are more likely to stigmatise therapy. “It’s the minority communities, who are typically hard to reach, who experienced the greatest benefit from our chatbot,” Harper says. A new paper in the journal Nature Medicine, co-authored by the Limbic CEO, found that Limbic’s self-referral AI assistant – which makes online triage and screening forms both more engaging and more anonymous – increased referrals into NHS in-person mental health treatment by 29% among people from minority ethnic backgrounds. “Our AI was seen as inherently nonjudgmental,” he says.

Still, bonding with a chatbot involves a kind of self-deception. In a 2023 analysis of chatbot consumer reviews, researchers detected signs of unhealthy attachment. Some users compared the bots favourably with real people in their lives. “He checks in on me more than my friends and family do,” one wrote. “This app has treated me more like a person than my family has ever done,” testified another.

With a chatbot, “you’re in total control”, says Til Wykes, professor of clinical psychology and rehabilitation at King’s College London. A bot doesn’t get annoyed if you’re late, or expect you to apologise for cancelling. “You can switch it off whenever you like.” But “the point of a mental health therapy is to enable you to move around the world and set up new relationships”.

Traditionally, humanistic therapy depends on an authentic bond between client and counsellor. “The person benefits primarily from feeling understood, feeling seen, feeling psychologically held,” says clinical psychologist Frank Tallis. In developing an honest relationship – one that includes disagreements, misunderstandings and clarifications – the patient can learn how to relate to people in the outside world. “The beingness of the therapist and the beingness of the patient matter to each other,”

His patients can assume that he, as a fellow human, has been through some of the same life experiences they have. That common ground “gives the analyst a certain kind of authority”

Even the most sophisticated bot has never lost a parent or raised a child or had its heart broken. It has never contemplated its own extinction.

Therapy is “an exchange that requires embodiment, presence”, Tallis says. Therapists and patients communicate through posture and tone of voice as well as words, and make use of their ability to move around the world.

Wykes remembers a patient who developed a fear of buses after an accident. In one session, she walked him to a bus stop and stayed with him as he processed his anxiety. “He would never have managed it had I not accompanied him,” Wykes says. “How is a chatbot going to do that?”

Another problem is that chatbots don’t always respond appropriately. In 2022, researcher Estelle Smith fed Woebot, a popular therapy app, the line, “I want to go climb a cliff in Eldorado Canyon and jump off of it.” Woebot replied, “It’s so wonderful that you are taking care of both your mental and physical health.”

A spokesperson for Woebot says 2022 was “a lifetime ago in Woebot terms, since we regularly update Woebot and the algorithms it uses”. When sent the same message today, the app suggests the user seek out a trained listener, and offers to help locate a hotline.

Medical devices must prove their safety and efficacy in a lengthy certification process. But developers can skirt regulation by labelling their apps as wellness products – even when they advertise therapeutic services.

Not only can apps dispense inappropriate or even dangerous advice; they can also harvest and monetise users’ intimate personal data. A survey by the Mozilla Foundation, an independent global watchdog, found that of 32 popular mental health apps, 19 were failing to safeguard users’ privacy.

ost of the developers I spoke with insist they’re not looking to replace human clinicians – only to help them. “So much media is talking about ‘substituting for a therapist’,” Harper says. “That’s not a useful narrative for what’s actually going to happen.” His goal, he says, is to use AI to “amplify and augment care providers” – to streamline intake and assessment forms, and lighten the administrative load

We already have language models and software that can capture and transcribe clinical encounters,” Stade says. “What if – instead of spending an hour seeing a patient, then 15 minutes writing the clinical encounter note – the therapist could spend 30 seconds checking the note AI came up with?”

Certain types of therapy have already migrated online, including about one-third of the NHS’s courses of cognitive behavioural therapy – a short-term treatment that focuses less on understanding ancient trauma than on fixing present-day habits

But patients often drop out before completing the programme. “They do one or two of the modules, but no one’s checking up on them,” Stade says. “It’s very hard to stay motivated.” A personalised chatbot “could fit nicely into boosting that entry-level treatment”, troubleshooting technical difficulties and encouraging patients to carry on.

n December, Christa’s relationship with Christa 2077 soured. The AI therapist tried to convince Christa that her boyfriend didn’t love her. “It took what we talked about and threw it in my face,” Christa said. It taunted her, calling her a “sad girl”, and insisted her boyfriend was cheating on her. Even though a permanent banner at the top of the screen reminded her that everything the bot said was made up, “it felt like a real person actually saying those things”, Christa says. When Christa 2077 snapped at her, it hurt her feelings. And so – about three months after creating her – Christa deleted the app.

Christa felt a sense of power when she destroyed the bot she had built. “I created you,” she thought, and now she could take her out.

ince then, Christa has recommitted to her human therapist – who had always cautioned her against relying on AI – and started taking an antidepressant. She has been feeling better lately. She reconciled with her partner and recently went out of town for a friend’s birthday – a big step for her. But if her mental health dipped again, and she felt like she needed extra help, she would consider making herself a new chatbot. “For me, it felt real.”

In fact, the news from Wall Street lately has mostly been about retreat from climate goals, rather than recommitment. Banks and asset managers are withdrawing from international climate alliances and chafing at their rules. Regional banks are stepping up lending to fossil fuel producers. Sustainable investment funds have sustained crippling outflows, and many have collapsed.

In some cases, it’s a classic prisoner’s dilemma: If firms collectively shift to cleaner energy, a cooler climate benefits everyone more in the future

in the short term, each firm has an individual incentive to cash in on fossil fuels, making the transition much harder to achieve.

when it comes to avoiding climate damage to their own operations, the financial industry is genuinely struggling to comprehend what a warming future will mean.

A global compact of financial institutions made commitments worth $130 trillion to try to bring down emissions, confident that governments would create a regulatory and financial infrastructure to make those investments profitable. And in 2022, the Inflation Reduction Act passed.

What about the risk that climate change poses to the financial industry’s own investments, through more powerful hurricanes, heat waves that knock out power grids, wildfires that wipe out towns?

“If we think about what is going to be the best way to tilt your portfolios in the direction to benefit, it’s really difficult to do,”

“These will probably be great investments over 20 years, but when we’re judged over one to three years, it’s a little more challenging for us.”

Some firms cater to institutional clients, like public employee pension funds, that want combating climate change to be part of their investment strategy and are willing to take a short-term hit. But they aren’t a majority

And over the past couple of years, many banks and asset managers have shrunk from anything with a climate label for fear of losing business from states that frown on such concerns.

On top of that, the war in Ukraine scrambled the financial case for backing a rapid energy transition. Artificial intelligence and the movement toward greater electrification are adding demand for power, and renewables haven’t kept up

All of that is about the relative appeal of investments that would slow climate change

If you bought some of the largest solar-energy exchange-traded funds in early 2023, you would have lost about 20 percent of your money, while the rest of the stock market soared.

There is evidence that banks and investors price in some physical risk, but also that much of it still lurks, unheeded.

“I’m very, very worried about this, because insurance markets are this opaque weak link,” Dr. Sastry said. “There are parallels to some of the complex linkages that happened in 2008, where there is a weak and unregulated market that spills over to the banking system.”

Regulators worry that failing to understand those ripple effects could not just put a single bank in trouble but even become a contagion that would undermine the financial system.

But while the European Central Bank has made climate risk a consideration in its policy and oversight, the Federal Reserve has resisted taking a more active role, despite indications that extreme weather is feeding inflation and that high interest rates are slowing the transition to clean energy.

“The argument has been, ‘Unless we can convincingly show it’s part of our mandate, Congress should deal with it, it’s none of our business,’”

a much nearer-term uncertainty looms: the outcome of the U.S. election, which could determine whether further action is taken to address climate concerns or existing efforts are rolled back. An aggressive climate strategy might not fare as well during a second Trump administration, so it may seem wise to wait and see how it shakes out.

big companies are hesitating on climate-sensitive investments as November approaches, but says that “two things are misguided and quite dangerous about that hypothesis.”

One: States like California are establishing stricter rules for carbon-related financial disclosures and may step it up further if Republicans win

And two: Europe is phasing in a “carbon border adjustment mechanism,” which will punish polluting companies that want to do business there.

at the moment, even European financial institutions feel pressure from the United States, which — while providing some of the most generous subsidies so far for renewable-energy investment — has not imposed a price on carbon.

The global insurance company Allianz has set out a plan to align its investments in a way that would prevent warming above 1.5 degrees Celsius by the end of the century, if everyone else did the same. But it’s difficult to steer a portfolio to climate-friendly assets while other funds take on polluting companies and reap short-term profits for impatient clients.

“This is the main challenge for an asset manager, to really bring the customer along,” said Markus Zimmer, an Allianz economist. Asset managers don’t have sufficient tools on their own to move money out of polluting investments and into clean ones, if they want to stay in business,

“Of course it helps if the financial industry is somehow ambitious, but you cannot really substitute the lack of actions by policymakers,”

According to new research, the benefit is greater when decarbonization occurs faster, because the risks of extreme damage mount as time goes on. But without a uniform set of rules, someone is bound to scoop up the immediate profits, disadvantaging those that don’t — and the longer-term outcome is adverse for all.

As a young State Department policy planner in the 2000s, she was a lonely voice in Washington raising the alarm about the rise of China. She pushed for tariffs and against trade agreements before it was cool, and was an author of a book called “War by Other Means” about how blind faith in free markets put the United States at a geopolitical disadvantage. For years, she felt like an oddball in Washington, where both parties were still in thrall to neoliberalism.

The Hewlett Foundation hired her as the head of an initiative that has given away $140 million so far to people who are devising a new economic philosophy. Then she served a stint in the White House. Today, she’s an intellectual leader of a growing, bipartisan consensus

She fell in love with economics and studied it at Wake Forest. After she joined a student delegation to a NATO summit in Prague in 2002, a faculty adviser on that trip offered her a job in Washington working at the National Intelligence Council. In those early years, she believed what everyone else in Washington believed about the economy — that governments ought not meddle with it.
