An aperiodic tiling displays no such “translational symmetry,” and mathematicians have long sought a single shape that could tile the plane in such a fashion. This is known as the einstein problem.

“I’m always messing about and experimenting with shapes,” said Mr. Smith, 64, who worked as a printing technician, among other jobs, and retired early. Although he enjoyed math in high school, he didn’t excel at it, he said. But he has long been “obsessively intrigued” by the einstein problem.

now a new paper — by Mr. Smith and three co-authors with mathematical and computational expertise — proves Mr. Smith’s discovery true. The researchers called their einstein “the hat,

“The most significant aspect for me is that the tiling does not clearly fall into any of the familiar classes of structures that we understand.”

black and white squares also can make weird nonperiodic patterns, in addition to the familiar, periodic checkerboard pattern. “It’s really pretty trivial to be able to make weird and interesting patterns,” he said. The magic of the two Penrose tiles is that they make only nonperiodic patterns — that’s all they can do.“But then the Holy Grail was, could you do with one — one tile?” Dr. Goodman-Strauss said.

Sir Roger found the proofs “very complicated.” Nonetheless, he was “extremely intrigued” by the einstein, he said: “It’s a really good shape, strikingly simple.”

The simplicity came honestly. Mr. Smith’s investigations were mostly by hand; one of his co-authors described him as an “imaginative tinkerer.”

When in November he found a tile that seemed to fill the plane without a repeating pattern, he emailed Craig Kaplan, a co-author and a computer scientist at the University of Waterloo.

“It was clear that something unusual was happening with this shape,” Dr. Kaplan said. Taking a computational approach that built on previous research, his algorithm generated larger and larger swaths of hat tiles. “There didn’t seem to be any limit to how large a blob of tiles the software could construct,”

The first step, Dr. Kaplan said, was to “define a set of four ‘metatiles,’ simple shapes that stand in for small groupings of one, two, or four hats.” The metatiles assemble into four larger shapes that behave similarly. This assembly, from metatiles to supertiles to supersupertiles, ad infinitum, covered “larger and larger mathematical ‘floors’ with copies of the hat,” Dr. Kaplan said. “We then show that this sort of hierarchical assembly is essentially the only way to tile the plane with hats, which turns out to be enough to show that it can never tile periodically.”

some might wonder whether this is a two-tile, not one-tile, set of aperiodic monotiles.

Dr. Goodman-Strauss had raised this subtlety on a tiling listserv: “Is there one hat or two?” The consensus was that a monotile counts as such even using its reflection. That leaves an open question, Dr. Berger said: Is there an einstein that will do the job without reflection?

“the hat” was not a new geometric invention. It is a polykite — it consists of eight kites. (Take a hexagon and draw three lines, connecting the center of each side to the center of its opposite side; the six shapes that result are kites.)

“It’s likely that others have contemplated this hat shape in the past, just not in a context where they proceeded to investigate its tiling properties,” Dr. Kaplan said. “I like to think that it was hiding in plain sight.”

Incredibly, Mr. Smith later found a second einstein. He called it “the turtle” — a polykite made of not eight kites but 10. It was “uncanny,” Dr. Kaplan said. He recalled feeling panicked; he was already “neck deep in the hat.”

Dr. Myers, who had done similar computations, promptly discovered a profound connection between the hat and the turtle. And he discerned that, in fact, there was an entire family of related einsteins — a continuous, uncountable infinity of shapes that morph one to the next.

this einstein family motivated the second proof, which offers a new tool for proving aperiodicity. The math seemed “too good to be true,” Dr. Myers said in an email. “I wasn’t expecting such a different approach to proving aperiodicity — but everything seemed to hold together as I wrote up the details.”

Mr. Smith was amazed to see the research paper come together. “I was no help, to be honest.” He appreciated the illustrations, he said: “I’m more of a pictures person.”

he started receiving death threats. People said they wished he and his family had been killed by drug lords, told him that “sooner or later your punishment will arrive” and proposed that he be nailed into a coffin or run over by a cement roller.

Mr. Moreno, who grew up in Colombia, began working as a researcher in a computer science and robotics lab in Paris in 1983; the career that followed involved creating a start-up, meeting the Dalai Lama and being named a knight of the Légion d’Honneur. His work has won several awards and spanned many fields — automotive, medical, nuclear, military, even home goods.

Many of the recent threats have been directed at scientists studying Covid-19. In a survey of 321 such scientists who had given media interviews, the journal Nature found that 22 percent had received threats of physical or sexual violence and 15 percent had received death threats

Last year, an Austrian doctor who was a vocal supporter of vaccines and a repeated target of threats died by suicide.

increasingly, even professors and researchers without much of a public persona have faced intimidation from extremists and conspiracy theorists.

Around 2010, he started thinking about how technology could help create sustainable cities. Eventually, he refined his ideas about “human smart cities” and “living cities” into his 2016 proposal for 15-minute cities.

The idea owes much to its many predecessors: “neighborhood units” and “garden cities” in the early 1900s, the community-focused urban planning pioneered by the activist Jane Jacobs in the 1960s, even support for “new urbanism” and walkable cities in the 1990s. So-called low-traffic neighborhoods, or LTNs, have been set up in several British cities over the past few decades.

Critics of 15-minute cities have been outspoken, arguing that a concept developed in Europe may not translate well to highly segregated American cities. A Harvard economist wrote in a blog post for the London School of Economics and Political Science in 2021 that the concept was a “dead end” that would exacerbate “enormous inequalities in cities” by subdividing without connecting them.

Jordan Peterson, a Canadian psychologist with four million Twitter followers, suggested that 15-minute cities were “perhaps the worst imaginable perversion” of the idea of walkable neighborhoods. He linked to a post about the “Great Reset,” an economic recovery plan proposed by the World Economic Forum that has spawned hordes of rumors about a pandemic-fueled plot to destroy capitalism.

A member of Britain’s Parliament said that 15-minute cities were “an international socialist concept” that would “cost us our personal freedoms.” QAnon supporters said the derailment of a train carrying hazardous chemicals in Ohio was an intentional move meant to push rural residents into 15-minute cities.

“Conspiracy-mongers have built a complete story: climate denialism, Covid-19, anti-vax, 5G controlling the brains of citizens, and the 15-minute city for introducing a perimeter for day-to-day life,” Mr. Moreno said. “This storytelling is totally insane, totally irrational for us, but it makes sense for them.”

The multipronged conspiracy theory quickly became “turbocharged” after the Oxford protest, said Jennie King, head of climate research and policy at the Institute for Strategic Dialogue, a think tank that studies online platforms.

“You have this snowball effect of a policy, which in principle was only going to affect a small urban population, getting extrapolated and becoming this crucible where far-right groups, industry-sponsored lobbying groups, conspiracist movements, anti-lockdown groups and more saw an opportunity to insert their worldview into the mainstream and to piggyback on the news cycle,”

The vitriol currently directed at Mr. Moreno and researchers like him mirrors “the broader erosion of trust in experts and institutions,”

Modern conspiracy theorists and extremists turn the people they disagree with into scapegoats for a vast array of societal ills, blaming them personally for causing the high cost of living or various health crises and creating an “us-versus-them” environment, she said.

“I am not a politician, I am not a candidate for anything — as a researcher, my duty is to explore and deepen my ideas with scientific methodology,” he said. “It is totally unbelievable that we could receive a death threat just for working as scientists.”

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.

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.

Apple and Google said they allow users to create audiobooks free of charge that use digitally replicated human voices. The voices featured in audiobooks generated by Apple and Google come from real people, whose voices helped train their automated-narration engines.

Ms. Papel said there is still plenty of work for professional narrators because the new era of AI auto-narration is just getting under way, though she said that might not be the case in the future.

“From what I can see, human narrators are freaking out,

Melissa Papel, a Paris-born actress who records from her home studio in Los Angeles, said she recorded eight hours of content for DeepZen, reading in French from different books. “One called for me to read in an angry way, another in a disgusted way, a humorous way, a dramatic way,” she said.

Charles Watkinson, director of the University of Michigan Press, said the publisher has made about 100 audiobooks using Google’s free auto-narrated audiobook platform since early last year. The new technology made those titles possible because it eliminated the costs associated with using a production studio, support staff and human narrators.

“I understood that they would use my voice to teach software how to speak more humanly,” Ms. Papel said. “I didn’t realize they could use my voice to pronounce words I didn’t say. That’s incredible.”

DeepZen pays its narrators a flat fee plus a royalty based on the revenue the company generates from different projects. The agreements span multiple years

a national union that represents performers, including professional audiobook narrators, said he expects AI to eventually disrupt the industry.

Audiobook sales rose 7% last year, according to the Association of American Publishers, while print book sales declined by 5.8%, according to book tracker Circana BookScan.

eepZen says it has signed deals with 35 publishers in the U.S. and abroad and is working with 25 authors.

Josiah Ziegler, a psychiatrist in Fort Collins, Colo., last year created Intellectual Classics, which focuses on nonfiction works that are out of copyright and don’t have an audiobook edition. 

He chose Mr. Herrmann as the narrator for “The War with Mexico,” a work by Justin H. Smith that won the 1920 Pulitzer Prize for history whose audiobook version Dr. Ziegler expects to publish later this year.

DeepZen, which has created nearly a hundred audiobooks featuring Mr. Herrmann’s voice, is pursuing the rights of other well-known stars who have died.

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.

The book recounts four peak periods in the conflict between white Alabamians and the federal government: the wild rush, in the early 19th century, to seize and settle lands that belonged to the Creek Nation; Reconstruction; the reassertion of white supremacy under Jim Crow; and the attempts of Wallace and others to nullify the civil rights reforms of the 1950s and 1960s.

Throughout, as Cowie reveals, white Southerners portrayed the oppression of Black people and Native Americans not as a repudiation of freedom, but its precondition, its very foundation.

Following the election of Ulysses S. Grant in 1868 and the ratification of the 14th and 15th Amendments, the federal presence in the South was finally robust. So was the spirit of local defiance. In post-bellum Barbour County, Cowie writes, “peace only prevailed for freed people when federal troops were in town” — and then only barely

White men did all this in Barbour County, by design and without relent, and Cowie’s account of their acts is unsparing. His narrative is immersive; his characters are vividly rendered, whether familiar figures like Andrew Jackson or mostly forgotten magnates like J.W. Comer, a plantation owner who became, in the late 19th century, the architect of a vast, sadistic and extremely lucrative system of convict labor

Thus were white men, in the words of the scholar Orlando Patterson, whom Cowie quotes, “free to brutalize.” Thus were they free “to plunder and lay waste and call it peace, to rape and humiliate, to invade, conquer, uproot and degrade.”

the chaos in Alabama offended Jackson’s sense of discipline and made a mockery of his treaties with the Creeks. Beginning in 1832, and in fits and starts over the following year, federal troops looked to turn back or at least contain the white wave. Instead, their presence touched off a series of violent reprisals, created a cast of martyrs and folk heroes, and gave rise to the mythology of white victimization. Self-rule and local authority — rhetorical wrapping for this will to power — had become articles of faith, fervid as any religious belief.

The federal government is a character here, too — sometimes in a central role, sometimes remote to the point of irrelevance, and all too often feckless in the defense of a more inclusive, affirmative model of freedom.

When Grant stepped up the enforcement of voting rights, whites in Eufaula, Barbour County’s largest town, massacred Black citizens and engaged in furious efforts to manipulate or overturn elections. As in the 1830s, the federal government showed little stamina for the struggle. Republican losses in 1874 augured another retreat, this time for the better part of a century. In the vacuum, Cowie explains, emerged “the neoslavery of convict leasing, the vigilante justice of lynching, the degradation and debt of sharecropping and the official disenfranchisement of Blacks” under Jim Crow.

Wallace, as Cowie makes clear, had bigger ambitions. Instinctively, he knew that his brand of politics had an audience anywhere that white Americans were under strain and looking for someone to blame. Wallace became the sneering face of the backlash against the Civil Rights Act and the Voting Rights Act, against any law or court ruling or social program that aimed to include Black Americans more fully in our national life. Racism was central to his appeal, yet its common note was grievance; the common enemies were elites, the press and the federal government. “Being a Southerner is no longer geographic,” he declared in 1964, during the first of his four runs for the White House. “It’s a philosophy and an attitude.”

That attitude, we know, is pervasive now — a primal, animating principle of conservative politics. We hear it in conspiracy theories about the “deep state”; we see it in the actions of Republican officials like Gov. Ron DeSantis of Florida, who built a case for his re-election in 2022 by banning — in the name of “individual freedom” — classroom discussions of gender, sexuality and systemic racism.

In explaining how we got here, “Freedom’s Dominion” emphasizes race above economics, but this seems fitting. The fixation on the free market, so long a defining feature of the Republican Party, has loosened its hold; taxes and regulations do not boil the blood as they once did. In their place is a stew of resentments as raw as any since George Wallace stirred the pot.

As one Twitter wag noted, Musk’s acquisition of Twitter is like Elmer Fudd buying a platform full of Bugs Bunnies.)

There is one more example of such resentment, and it’s a lot less funny. Russia is an entire nation seized with a massive inferiority complex, and the Russian regime is giving vent to that resentment in the continual murder of Ukrainians

As the British journalist Simon Kuper noted a few years ago, anti-system parties in the United Kingdom, Italy, and the United States are powered not by struggling workers, but by the “comfortably off populist voter” who has “never been invited into the fast lane of life: the top universities, the biggest firms, the major corporations.”

These citizens think that the disconnect between material success and their perceived lack of status must be punished, and if that means voting for election deniers and conspiracy theorists, so be it.

Trump and those like him managed to get a ticket in the swankiest carriage on the train, only to find themselves sitting alone. And if that’s how it’s going to be … well, the only answer is to derail the entire thing, from locomotive to caboose, and make everyone suffer.

the brutality of the Russians on the battlefield against their Slavic kin is very much rooted in resentment: Why do you live in freedom? Why are you living better than us?

But to understand why Republicans have died at higher rates, you can’t look at vaccine status alone. Congressional districts controlled by a trifecta of Republican leaders—state governor, Senate, and House—had an 11 percent higher death rate, according to the Lancet study. A likely explanation, the authors write, could be that in the post-vaccine era, those leaders chose policies and conveyed public-health messages that made their constituents more likely to die. Although we still can’t say these decisions led to higher death rates, the association alone is jarring.

One of the most compelling studies comes from researchers at Yale, who published their findings as a working paper in November. They link political party and excess-death rate—the percent increase in deaths above pre-COVID levels—among those registered as either Democrats or Republicans, providing a more granular view. They chose to analyze data from Florida and Ohio from before and after vaccines were available. Looking at the period before the vaccine,  researchers found a 1.6 percentage-point difference in excess death rate among Republicans and Democrats, with a higher rate among Republicans. But after vaccines became available, that gap widened dramatically to 10.4 percentage points, again with a higher Republican excess death rate. “When we compare individuals who are of the same age, who live in the same county in the same month of the pandemic, there are differences correlated with your political-party affiliation that emerge after vaccines are available,”

What’s most concerning about all of this is that partisan disparities in death rates were also apparent before COVID. People living in Republican jurisdictions have been at a health disadvantage for more than 20 years. From 2001 to 2019, the death rate in Democratic counties decreased by 22 percent, according to a recent study; in Republican counties, it declined by only 11 percent. In the same time period, the political gap in death rates increased sixfold.

over the decades, state policy decisions on health issues such as Medicaid, gun legislation, tobacco taxes, and, indeed, vaccines have likely had a stronger impact on state health trajectories than other factors

the long-term decline of health in red states indicates that there is an ongoing problem at a high level in Republican-led places, and that something has gone awry. “If you happen to live in certain states, your chances for living a long life are going to be much higher than if you’re an American living in a different state,”

o acknowledge how many Republicans didn’t have to die would mean giving credence to scientific and medical expertise. So long as America remains locked in a poisonous partisan battle in which science is wrongly dismissed as being associated with the left, the death toll will only rise.

Medical staff say they could have avoided the medicine shortages that have forced some facilities to ration drugs. There also could have been more time to set up a more effective triage system to avoid overcrowding

ne of the fundamental problems with China’s health system is its overreliance on hospitals for even the most basic care.

“In the U.S. people have their own primary physicians, but there are few ways in China to get care from the medical system except to go to an E.R. at a big hospital,” said Dr. Qiao Renli, a pulmonary and critical care doctor at the University of Southern California, who has taught and practiced medicine in both China and the United States.

The deluge of Covid patients is not the only challenge hospitals are facing. One of the ripple effects of the outbreak has been a widespread shortage of blood for transfusions because of the shrinking pool of eligible donors.In the southwestern city of Kunming, a blood bank said in a statement that the city was getting a fraction of the 500 donors per day it needs to keep up with demand, and that the shortage had started to affect pregnant women and patients in intensive care units.

During the 20th century, the list got much longer. In came existential crises, midlife crises, energy crises and environmental crises. When Koselleck was writing about the subject in the 1970s, he counted up more than 200 kinds of crisis we could then face

Waking up each morning to hear about the latest crisis is dispiriting for some, but throughout history it has been a bracing experience for others. In 1857, Friedrich Engels wrote in a letter that “the crisis will make me feel as good as a swim in the ocean”. A hundred years later, John F Kennedy (wrongly) pointed out that in the Chinese language, the word “crisis” is composed of two characters, “one representing danger, and the other, opportunity”. More recently, Elon Musk has argued “if things are not failing, you are not innovating enough”.

Victor H Mair, a professor of Chinese literature at the University of Pennsylvania, points out that in fact the Chinese word for crisis, wēijī, refers to a perilous situation in which you should be particularly cautious

“Those who purvey the doctrine that the Chinese word for ‘crisis’ is composed of elements meaning ‘danger’ and ‘opportunity’ are engaging in a type of muddled thinking that is a danger to society,” he writes. “It lulls people into welcoming crises as unstable situations from which they can benefit.” Revolutionaries, billionaires and politicians may relish the chance to profit from a crisis, but most people world prefer not to have a crisis at all.

A 2019 study which involved observing participants using bricks, found that those who had been threatened before the task tended to come up with more harmful uses of the bricks (such as using them as weapons) than people who did not feel threatened

The first world war sparked the growth of modernism in painting and literature. The second fuelled innovations in science and technology. The economic crises of the 1970s and 80s are supposed to have inspired the spread of punk and the creation of hip-hop

psychologists have also found that when we are threatened by a crisis, we become more rigid and locked into our beliefs. The creativity researcher Dean Simonton has spent his career looking at breakthroughs in music, philosophy, science and literature. He has found that during periods of crisis, we actually tend to become less creative.

When he looked at 5,000 creative individuals over 127 generations in European history, he found that significant creative breakthroughs were less likely during periods of political crisis and instability.

psychologists have found that it is what they call “malevolent creativity” that flourishes when we feel threatened by crisis.

These are innovations that tend to be harmful – such as new weapons, torture devices and ingenious scams.

A common folk theory is that times of great crisis also lead to great bursts of creativity.

Students presented with information about a threatening situation tended to become increasingly wary of outsiders, and even begin to adopt positions such as an unwillingness to support LGBT people afterwards.

during moments of crisis – when change is really needed – we tend to become less able to change.

When we suffer significant traumatic events, we tend to have worse wellbeing and life outcomes.

, other studies have shown that in moderate doses, crises can help to build our sense of resilience.

we tend to be more resilient if a crisis is shared with others. As Bruce Daisley, the ex-Twitter vice-president, notes: “True resilience lies in a feeling of togetherness, that we’re united with those around us in a shared endeavour.”

Crises are like many things in life – only good in moderation, and best shared with others

The challenge our leaders face during times of overwhelming crisis is to avoid letting us plunge into the bracing ocean of change alone, to see if we sink or swim. Nor should they tell us things are fine, encouraging us to hide our heads in the san

during moments of significant crisis, the best leaders are able to create some sense of certainty and a shared fate amid the seas of change.

This means people won’t feel an overwhelming sense of threat. It also means people do not feel alone. When we feel some certainty and common identity, we are more likely to be able to summon the creativity, ingenuity and energy needed to change things.

That has made him the most popular influencer among American Gen-Zers, according to a twice-yearly survey of 14,500 of the country’s teenage boys and girls by Piper Sandler, a finance company that researches consumer data. Teachers have reported boys as young as 11 praising and emulating him.

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.

Until recently, the people said, Meta executives viewed the company’s reliance on China to make Oculus virtual reality headsets as a relatively minor concern because the company’s core focus was its social media and messaging apps.

All that has changed now that Meta has rebranded itself as a hardware company

“Meta is building a complicated hardware product. You can’t just turn on a dime and make it elsewhere,”

Facebook’s public criticism of China began in 2019 when Zuckerberg warned, in a speech at Georgetown University, that China was exporting a dangerous vision for the internet to the rest of the world — and noted that Facebook was abandoning its efforts to break into that country’s market.

The anti-China stance has since extended into a full-blown corporate strategy. Nick Clegg, the company’s president, wrote an op-ed attacking China in The Washington Post in 2020, the same year Zuckerberg attacked China in a congressional antitrust hearing.

At the antitrust hearing in Congress in 2020, Zuckerberg used his opening remarks to attack China in terms that went much further than his industry peers. He said it was “well-documented that the Chinese government steals technology from American companies,” and repeated that the country was “building its own version of the internet” that went against American values. He described Facebook as a “proudly American” company and noted that TikTok was the company’s fastest-growing rival.

“They were trying to find things that [Zuckerberg] could agree with Trump on, and it’s a pretty slim list,” said one of the people, describing how the company landed on its anti-China strategy. “If you’re not going to try to be in this country anyway, you might as well use it to your political advantage by contrasting yourself with Apple and TikTok.”

“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.

For researchers concerned with more immediate AI risks, such as bias, disinformation and job displacement, the voices of doom are a distraction. Professor Brent Mittelstadt, director of research at the Oxford Internet Institute, said the warnings of “the existential risks community” are overblown. “The problem is you can’t disprove the future scenarios . . . in the same way you can’t disprove science fiction.” Emily Bender, a professor of linguistics at the University of Washington, believes the doomsters are propagating “unhinged AI hype, helping those building this stuff sell it”.

Those urging us to stop, pause and think again have a useful card up our sleeves: the people building these models do not fully understand them. AI like ChatGPT is made up of huge neural networks that can defy their creators by coming up with “emergent properties”.

Google’s PaLM model started translating Bengali despite not being trained to do so

Let’s not forget the excitement, because that is also part of Moloch, driving us forward. The lure of AI’s promises for humanity has been hinted at by DeepMind’s AlphaFold breakthrough, which predicted the 3D structures of nearly all the proteins known to humanity.

Noam Shazeer, a former Google engineer credited with setting large language models such as ChatGPT on their present path, was asked by The Sunday Times how the models worked. He replied: “I don’t think anybody really understands how they work, just like nobody really understands how the brain works. It’s pretty much alchemy.”

The industry is turning itself to understanding what has been created, but some predict it will take years, decades even.

Alex Heath, deputy editor of The Verge, who recently attended an AI conference in San Francisco. “It’s clear the people working on generative AI are uneasy about the worst-case scenario of it destroying us all. These fears are much more pronounced in private than they are in public.” One figure building an AI product “said over lunch with a straight face that he is savoring the time before he is killed by AI”.

Greg Brockman, co-founder of OpenAI, told the TED2023 conference this week: “We hear from people who are excited, we hear from people who are concerned. We hear from people who feel both those emotions at once. And, honestly, that’s how we feel.”

A CBS interviewer challenged Sundar Pichai, Google’s chief executive, this week: “You don’t fully understand how it works, and yet you’ve turned it loose on society?

In 2020 there wasn’t a single drug in clinical trials developed using an AI-first approach. Today there are 18

Consider this from Bill Gates last month: “I think in the next five to ten years, AI-driven software will finally deliver on the promise of revolutionising the way people teach and learn.”

If the industry is aware of the risks, is it doing enough to mitigate them? Microsoft recently cut its ethics team, and researchers building AI outnumber those focused on safety by 30-to-1,

The concentration of AI power, which worries so many, also presents an opportunity to more easily develop some global rules. But there is little agreement on direction. Europe is proposing a centrally defined, top-down approach. Britain wants an innovation-friendly environment where rules are defined by each industry regulator. The US commerce department is consulting on whether risky AI models should be certified. China is proposing strict controls on generative AI that could upend social order.

Part of the drive to act now is to ensure we learn the lessons of social media. Twenty years after creating it, we are trying to put it back in a legal straitjacket after learning that its algorithms understand us only too well. “Social media was the first contact between AI and humanity, and humanity lost,” Yuval Harari, the Sapiens author,

Others point to bioethics, especially international agreements on human cloning. Tegmark said last week: “You could make so much money on human cloning. Why aren’t we doing it? Because biologists thought hard about this and felt this is way too risky. They got together in the Seventies and decided, let’s not do this because it’s too unpredictable. We could lose control over what happens to our species. So they paused.” Even China signed up.

One voice urging calm is Yann LeCun, Meta’s chief AI scientist. He has labelled ChatGPT a “flashy demo” and “not a particularly interesting scientific advance”. He tweeted: “A GPT-4-powered robot couldn’t clear up the dinner table and fill up the dishwasher, which any ten-year-old can do. And it couldn’t drive a car, which any 18-year-old can learn to do in 20 hours of practice. We’re still missing something big for human-level AI.” If this is sour grapes and he’s wrong, Moloch already has us in its thrall.

“It’s shoot first, ask questions later,”

Each one of these incidents resulted from unique events. But activists and researchers say they stem from a convergence of bigger factors — increased fear of crime and an attendant surge in gun ownership, increasingly extreme political messaging on firearms, fearmongering in the media and marketing campaigns by the gun industry that portray the suburban front door as a fortified barrier against a violent world.

“The gun lobby markets firearms as something you need to defend yourself — hammers in search of nails,”

The perception that crime, especially violent gun crime, has increased is not a manufactured myth. National murder rates have climbed by about a third since 2019, according to government data, even accounting for modest declines in fatal shootings over the past 18 months.

Gun purchases rose during the pandemic and the unrest and racial-justice protests after the murder of George Floyd. Nearly 20 percent of American households bought a gun from March 2020 to March 2022, and about 5 percent of Americans bought a gun for the first time,

More than 30 states also have “stand your ground” laws. Some have recently strengthened their “castle doctrine” laws, making it more difficult to prosecute homeowners who claim self-defense in a shooting.

“People become paranoid and over-worried — and then comes an unannounced knock on their door,”

But several large-scale studies have suggested that the laws have few benefits, increase the likelihood of gun violence and might discriminate against minority groups, especially Black people.

The effect of self-defense laws protecting homeowners and gun owners is fiercely debated, with proponents arguing that their mere presence deters criminal behavior or civil disorder

shootings in which white people shot Black people were nearly three times as likely to be found “justified” compared with cases where white people shot other white people.

A 2023 analysis of recent academic research by the nonpartisan RAND Corporation found no evidence that such laws had the deterrent effect that their sponsors claimed, and there was some indication, while not conclusive, that the laws might account for some increases in gun violence.

weapons were actually more likely to be used in suicides, discharged accidentally, stolen or brandished in domestic disputes, than used to fend off an external attack.

The National Rifle Association and other gun-rights groups have long disputed such assessments, citing surveys that show far greater use of weapons for legitimate self-defense.

About a third of the roughly 16,700 gun owners surveyed in a study led by William English, a Georgetown University business school professor, said they had used their guns for self-defense, prompting Mr. English to estimate that as many as 1.6 million people in the country had defended themselves with a weapon that year.

lthough the concept of equality may seem intuitive, it is surprisingly difficult to pin down with any precision.

“When people speak of equality,” McMahon stresses, “they invariably speak of the equality of something.” The central question is the one so famously and pithily posed by the economist Amartya Sen in his landmark 1979 lecture of the same name: “Equality of what?”

McMahon surmises that our foraging forebears were probably staunch egalitarians, at least when it came to the division of labor within their communities.

even in the idyllic days of prehistory, there was a catch. Early humans probably adhered to what the anthropologist Christopher Boehm called an “egalitarian hierarchy,” in which, in McMahon’s words, “the many combine to dominate the few,” exiling those who challenged the pecking order (or so those cave paintings seem to suggest)

And even though hunter-gatherers probably treated suitably compliant members of their own clans equitably, in-group/out-group rivalries “undoubtedly played a role in the cohesion” that each group achieved internally

our ancestors maintained order within by sewing discord without, vying violently with competing clans and expelling (or even killing) upstarts who threatened to distinguish themselves too dramatically from the pack.

The very concept of equality, which requires both difference and sameness, generates comparable tensions in almost every society in which some version of it is promoted.

, the temptation to maintain harmony within a group by degrading those outside it has been irresistible for centuries — and remains so to this day.

But if the monotheistic religions “proclaimed fellowship among the children of God,” McMahon wryly clarifies, they were also “quick to banish from the family those who rejected the faith.

John Calvin himself minced no words on this point. “All are not created … equal,” he wrote.

Everyone was equal in post-revolution France — except for those who were not.

Many of the most prominent thinkers of the period considered women and people of color too irrational to merit legal recognition

in the 1700s, French revolutionaries inspired by the Enlightenment maintained that equality was a right bestowed on every man by virtue of his intrinsically rational nature

“We want to be treated with fairness and on equal terms, accorded recognition and respect,” McMahon writes. “But at the same time we seek distinction, aiming to set ourselves apart.

If equality so ineluctably contains the seeds of its own undoing, the moral arc of the universe cannot be trusted to bend toward justice. On the contrary, McMahon argues, equality is not an inevitability but a hard-earned improbability.

it is not equality but its opposite that is always encroaching, dogging every attempt at progress, stalking its rival like a shadow, patiently waiting to strike.

In his ambitious new book, “Equality: The History of an Elusive Idea,” Dartmouth history professor Darrin M. McMahon proposes that the “elusive idea” in question is expansive enough to vindicate both accounts. His wide-ranging survey of equality throughout the ages demonstrates that progress toward achieving it is almost never linear.

guided by a fascination with the wayward paths to fame, he half-unwittingly sows doubt about the justice of the American rise to artistic leadership in the postwar era. In his erudite account, artistic success owes little to vision and purpose, more to self-promotion, but most to unanticipated adoption by bigger systems with other aims, principally oriented toward money, political advantage, or commercial churn

For the greatness and inevitability of artistic consecration, Menand substitutes the arbitrary confluences of forces at any given moment.

The curriculum runs chapter by chapter through George Kennan, George Orwell, Jean-Paul Sartre, Hannah Arendt, Jackson Pollock, Lionel Trilling, Allen Ginsberg, Claude Lévi-Strauss, Robert Rauschenberg and John Cage, Elvis and the Beatles, Isaiah Berlin, James Baldwin, Jack Kerouac, Andy Warhol, Susan Sontag, and Pauline Kael. Each biography opens a door to a school or trend of work

Menand’s is not a “great man” view of history, because no one seems particularly great. One gets a feeling for Sartre as a person, a limited knowledge of how Sartre made Being and Nothingness, and a vivid sense of how the book made Sartre a celebrity. Then one learns how a troupe of others came along and rode his success like a sled.

Menand zooms in and out between individual egomaniacs and the milieus that facilitated their ascent and profited from their publicity.

group biographies, in miniature, of the existentialists, the Beats, the action painters, the Black Mountain School, the British Invasion, the pop artists, and many coteries more—are enchanting singly but demoralizing as they pile up

All of these enterprises look like hives of social insects, not selfless quests for truth or beauty. Menand is a world-class entomologist: He can name every indistinguishable drone, knows who had an oversize mandible, who lost a leg, who carried the best crumbs.

From this vantage, the monuments really are just anthills.

Menand is truly one of the great explainers. He quotes approvingly a lesson taken by Lionel Trilling from his editor Elliot Cohen: “No idea was so difficult and complex but that it could be expressed in a way that would make it understood by anyone to whom it might conceivably be of interest.”

The underlying theory of the book rests on a picture of what makes for “cultural winners,” works and ideas that Menand defines as

He is accurate, he is insightful, and he is not a dumber-downer

Menand’s account of each is an abbreviated tour de force. His explanations work at all levels: interpretation for scholars, review for general readers, introductions for neophytes. Where another writer would take 20 pages to tell us why someone or something mattered historically, Menand does it in two.

goods or styles that maintain market share through “generational” taste shifts—that is, through all the “the king is dead; long live the king” moments that mark the phases of cultural history for people living through it.

Menand’s recountings are less concerned with the changing meanings of individual works than with their successive adoptions and co-optations, in defiance of depth and meaning. It is a process of “winning” often based on cults of personality, indifference to complex origins, and the fortune or misfortune of timing

Menand is notably excellent on how commercial, regulatory, and technological changes determined which kinds of artwork made it to the public. His analysis helps demystify trends in commercial forms like film and pop music, especially when they otherwise seemed to run against the grain of pure profit

Often Menand’s point seems to be that the culture’s reigning talkers and salespeople and debaters need to conjure figures to venerate and attack (in ceaseless alternation) for short-range purposes of attention and competition. Any given work—1984, say, or Bonnie and Clyde—isn’t much of anything until it becomes a counter in other people’s games.

The central question of this period in culture might be whether U.S. artists lived up to expectations

In 1945, Europe was in ruins. America was rich and productive and dictated the terms of the postwar economic and political order. Certainly the U.S. had the power to pretend to cultural glory, too. But was it a pretense, or did Americans really continue and exceed the prewar triumphs of European modernism?

Most histories of the arts after 1945 assume that the greatest American successes deserved their fame.

The thrust of many of Menand’s retellings is that “in the business of cultural exchange, misprision is often the key to transmission.” Fame comes through misreadings, fantasies, unintended resonances, charisma, and publicity.

Menand’s book bequeaths the sense that the last laugh may truly have been on the self-seriousness of a whole historical period, one that treated its most publicized and successful arts figures far too generously, giving them too much credit for depth and vision, while missing the cynical forces by which they’d been buoyed up and marketed

“Foreign film” in America in the ’50s and ’60s—when independent art cinemas emerged, showing imports such as work by Ingmar Bergman and the French New Wave—proves to have been energized by a successful federal-government antitrust action against the monopolistic Hollywood studios

The idea of a “culture industry”

is used unironically by Menand to name the vastly scaled-up production and consumption of all artistic experience. “The culture industries, as they expanded, absorbed and commercialized independent and offbeat culture-makers, and the university, as it expanded, swallowed up the worlds of creative writing and dissident political opinion.”

With his eye on this process, we miss out on artists and thinkers who dug deep and stayed home, who produced as hermits or eccentrics or introverted students of their art

Where did rock ’n’ roll come from?” Menand wonders. He answers that it was “the by-product of a number of unrelated developments in the American music business” that redirected sales to teenagers, and also the result of new radio-station competition, the partial racial desegregation of the music charts, and the arrival of 200-disc jukeboxes

I can imagine The Free World leaving my hypothetical college senior, denizen of the bleak attention economy of the 21st century, feeling liberated to discover that culture was no better—no more committed to a quest for what is true, noble, lasting, and beautiful—in the world of the Baby Boomers and beaming grandparents.

The book is so masterful, and exhibits such brilliant writing and exhaustive research, that I wonder whether Menand could truly have intended where his history of the postwar era landed me. I learned so much, and ended up caring so much les

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

In the meantime, thinness was coming back into fashion

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