They worried that a vaccine would initially elude scientists, that weary citizens would abandon restrictions despite the risks, that the virus would be with us from now on.

Most experts believed that once the crisis was over, the nation and its economy would revive quickly. But there would be no escaping a period of intense pain.

Exactly how the pandemic will end depends in part on medical advances still to come. It will also depend on how individual Americans behave in the interim. If we scrupulously protect ourselves and our loved ones, more of us will live. If we underestimate the virus, it will find us.

More Americans may die than the White House admits.

The epidemiological model often cited by the White House, which was produced by the University of Washington’s Institute for Health Metrics and Evaluation, originally predicted 100,000 to 240,000 deaths by midsummer. Now that figure is 60,000.

The institute’s projection runs through Aug. 4, describing only the first wave of this epidemic. Without a vaccine, the virus is expected to circulate for years, and the death tally will rise over time.

Fatality rates depend heavily on how overwhelmed hospitals get and what percentage of cases are tested. China’s estimated death rate was 17 percent in the first week of January, when Wuhan was in chaos, according to a Center for Evidence-Based Medicine report, but only 0.7 percent by late February.

Various experts consulted by the Centers for Disease Control and Prevention in March predicted that the virus eventually could reach 48 percent to 65 percent of all Americans, with a fatality rate just under 1 percent, and would kill up to 1.7 million of them if nothing were done to stop the spread.

A model by researchers at Imperial College London cited by the president on March 30 predicted 2.2 million deaths in the United States by September under the same circumstances.

China has officially reported about 83,000 cases and 4,632 deaths, which is a fatality rate of over 5 percent. The Trump administration has questioned the figures but has not produced more accurate ones.

The tighter the restrictions, experts say, the fewer the deaths and the longer the periods between lockdowns. Most models assume states will eventually do widespread temperature checks, rapid testing and contact tracing, as is routine in Asia.

In this country, hospitals in several cities, including New York, came to the brink of chaos.

Only when tens of thousands of antibody tests are done will we know how many silent carriers there may be in the United States. The C.D.C. has suggested it might be 25 percent of those who test positive. Researchers in Iceland said it might be double that.

China is also revising its own estimates. In February, a major study concluded that only 1 percent of cases in Wuhan were asymptomatic. New research says perhaps 60 percent were.

The virus may also be mutating to cause fewer symptoms. In the movies, viruses become more deadly. In reality, they usually become less so, because asymptomatic strains reach more hosts. Even the 1918 Spanish flu virus eventually faded into the seasonal H1N1 flu.

The lockdowns will end, but haltingly.

it is likely a safe bet that at least 300 million of us are still vulnerable.

Until a vaccine or another protective measure emerges, there is no scenario, epidemiologists agreed, in which it is safe for that many people to suddenly come out of hiding. If Americans pour back out in force, all will appear quiet for perhaps three weeks.

The gains to date were achieved only by shutting down the country, a situation that cannot continue indefinitely. The White House’s “phased” plan for reopening will surely raise the death toll no matter how carefully it is executed.

Every epidemiological model envisions something like the dance

On the models, the curves of rising and falling deaths resemble a row of shark teeth.

Surges are inevitable, the models predict, even when stadiums, churches, theaters, bars and restaurants remain closed, all travelers from abroad are quarantined for 14 days, and domestic travel is tightly restricted to prevent high-intensity areas from reinfecting low-intensity ones.

In his wildly popular March 19 article in Medium, “Coronavirus: The Hammer and the Dance,” Tomas Pueyo correctly predicted the national lockdown, which he called the hammer, and said it would lead to a new phase, which he called the dance, in which essential parts of the economy could reopen, including some schools and some factories with skeleton crews.

Even the “Opening Up America Again” guidelines Mr. Trump issued on Thursday have three levels of social distancing, and recommend that vulnerable Americans stay hidden. The plan endorses testing, isolation and contact tracing — but does not specify how these measures will be paid for, or how long it will take to put them in place.

On Friday, none of that stopped the president from contradicting his own message by sending out tweets encouraging protesters in Michigan, Minnesota and Virginia to fight their states’ shutdowns.

China did not allow Wuhan, Nanjing or other cities to reopen until intensive surveillance found zero new cases for 14 straight days, the virus’s incubation period.

Compared with China or Italy, the United States is still a playground.Americans can take domestic flights, drive where they want, and roam streets and parks. Despite restrictions, everyone seems to know someone discreetly arranging play dates for children, holding backyard barbecues or meeting people on dating apps.

Even with rigorous measures, Asian countries have had trouble keeping the virus under control

But if too many people get infected at once, new lockdowns will become inevitable. To avoid that, widespread testing will be imperative.

Reopening requires declining cases for 14 days, the tracing of 90 percent of contacts, an end to health care worker infections, recuperation places for mild cases and many other hard-to-reach goals.

Immunity will become a societal advantage.

Imagine an America divided into two classes: those who have recovered from infection with the coronavirus and presumably have some immunity to it; and those who are still vulnerable.

“It will be a frightening schism,” Dr. David Nabarro, a World Health Organization special envoy on Covid-19, predicted. “Those with antibodies will be able to travel and work, and the rest will be discriminated against.”

Soon the government will have to invent a way to certify who is truly immune. A test for IgG antibodies, which are produced once immunity is established, would make sense

Dr. Fauci has said the White House was discussing certificates like those proposed in Germany. China uses cellphone QR codes linked to the owner’s personal details so others cannot borrow them.

As Americans stuck in lockdown see their immune neighbors resuming their lives and perhaps even taking the jobs they lost, it is not hard to imagine the enormous temptation to join them through self-infection

My daughter, who is a Harvard economist, keeps telling me her age group needs to have Covid-19 parties to develop immunity and keep the economy going,”

It would be a gamble for American youth, too. The obese and immunocompromised are clearly at risk, but even slim, healthy young Americans have died of Covid-19.

The virus can be kept in check, but only with expanded resources.

Resolve to Save Lives, a public health advocacy group run by Dr. Thomas R. Frieden, the former director of the C.D.C., has published detailed and strict criteria for when the economy can reopen and when it must be closed.

once a national baseline of hundreds of thousands of daily tests is established across the nation, any viral spread can be spotted when the percentage of positive results rises.

To keep the virus in check, several experts insisted, the country also must start isolating all the ill — including mild cases.

“If I was forced to select only one intervention, it would be the rapid isolation of all cases,”

In China, anyone testing positive, no matter how mild their symptoms, was required to immediately enter an infirmary-style hospital — often set up in a gymnasium or community center outfitted with oxygen tanks and CT scanners.

There, they recuperated under the eyes of nurses. That reduced the risk to families, and being with other victims relieved some patients’ fears.

Still, experts were divided on the idea of such wards

Ultimately, suppressing a virus requires testing all the contacts of every known case. But the United States is far short of that goal.

In China’s Sichuan Province, for example, each known case had an average of 45 contacts.

The C.D.C. has about 600 contact tracers and, until recently, state and local health departments employed about 1,600, mostly for tracing syphilis and tuberculosis cases.

China hired and trained 9,000 in Wuhan alone. Dr. Frieden recently estimated that the United States will need at least 300,000.

There will not be a vaccine soon.

any effort to make a vaccine will take at least a year to 18 months.

the record is four years, for the mumps vaccine.

for unclear reasons, some previous vaccine candidates against coronaviruses like SARS have triggered “antibody-dependent enhancement,” which makes recipients more susceptible to infection, rather than less. In the past, vaccines against H.I.V. and dengue have unexpectedly done the same.

A new vaccine is usually first tested in fewer than 100 young, healthy volunteers. If it appears safe and produces antibodies, thousands more volunteers — in this case, probably front-line workers at the highest risk — will get either it or a placebo in what is called a Phase 3 trial.

It is possible to speed up that process with “challenge trials.” Scientists vaccinate small numbers of volunteers, wait until they develop antibodies, and then “challenge” them with a deliberate infection to see if the vaccine protects them.

Normally, it is ethically unthinkable to challenge subjects with a disease with no cure, such as Covid-19.

“Fewer get harmed if you do a challenge trial in a few people than if you do a Phase 3 trial in thousands,” said Dr. Lipsitch, who recently published a paper advocating challenge trials in the Journal of Infectious Diseases. Almost immediately, he said, he heard from volunteers.

The hidden danger of challenge trials, vaccinologists explained, is that they recruit too few volunteers to show whether a vaccine creates enhancement, since it may be a rare but dangerous problem.

if a vaccine is invented, the United States could need 300 million doses — or 600 million if two shots are required. And just as many syringes.

“People have to start thinking big,” Dr. Douglas said. “With that volume, you’ve got to start cranking it out pretty soon.”

Treatments are likely to arrive first.

The modern alternative is monoclonal antibodies. These treatment regimens, which recently came very close to conquering the Ebola epidemic in eastern Congo, are the most likely short-term game changer, experts said.

as with vaccines, growing and purifying monoclonal antibodies takes time. In theory, with enough production, they could be used not just to save lives but to protect front-line workers.

Having a daily preventive pill would be an even better solution, because pills can be synthesized in factories far faster than vaccines or antibodies can be grown and purified.

Goodbye, ‘America First.’

A public health crisis of this magnitude requires international cooperation on a scale not seen in decades. Yet Mr. Trump is moving to defund the W.H.O., the only organization capable of coordinating such a response.

And he spent most of this year antagonizing China, which now has the world’s most powerful functioning economy and may become the dominant supplier of drugs and vaccines. China has used the pandemic to extend its global influence, and says it has sent medical gear and equipment to nearly 120 countries.

This is not a world in which “America First” is a viable strategy, several experts noted.

“If President Trump cares about stepping up the public health efforts here, he should look for avenues to collaborate with China and stop the insults,”

If we alienate the Chinese with our rhetoric, I think it will come back to bite us,” he said.“What if they come up with the first vaccine? They have a choice about who they sell it to. Are we top of the list? Why would we be?”

Once the pandemic has passed, the national recovery may be swift. The economy rebounded after both world wars, Dr. Mulder noted.

In one of the most provocative analyses in his follow-up article, “Coronavirus: Out of Many, One,” Mr. Pueyo analyzed Medicare and census data on age and obesity in states that recently resisted shutdowns and counties that voted Republican in 2016.

He calculated that those voters could be 30 percent more likely to die of the virus.

In the periods after both wars, Dr. Mulder noted, society and incomes became more equal. Funds created for veterans’ and widows’ pensions led to social safety nets, measures like the G.I. Bill and V.A. home loans were adopted, unions grew stronger, and tax benefits for the wealthy withered.

If a vaccine saves lives, many Americans may become less suspicious of conventional medicine and more accepting of science in general — including climate change

titled “Tightness-Looseness Across the 50 United States,” the study calculated a catalog of measures for each state, including the incidence of natural disasters, disease prevalence, residents’ levels of openness and conscientiousness, drug and alcohol use, homelessness and incarceration rates.

Gelfand said:Some groups have much stronger norms than others; they’re tight. Others have much weaker norms; they’re loose. Of course, all cultures have areas in which they are tight and loose — but cultures vary in the degree to which they emphasize norms and compliance with them.

states in New England and on the West Coast were the loosest: California, Oregon, Washington, Maine, Massachusetts, Connecticut, New Hampshire and Vermont.

In both 2016 and 2020, Donald Trump carried all 10 of the top “tight” states; Hillary Clinton and Joe Biden carried all 10 of the top “loose” states.

“Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire the World” in 2018, in which she described the results of a 2016 pre-election survey she and two colleagues had commissioned

The results were telling: People who felt the country was facing greater threats desired greater tightness. This desire, in turn, correctly predicted their support for Trump. In fact, desired tightness predicted support for Trump far better than other measures. For example, a desire for tightness predicted a vote for Trump with 44 times more accuracy than other popular measures of authoritarianism.

The 2016 election, Gelfand continued, “turned largely on primal cultural reflexes — ones that had been conditioned not only by cultural forces, but by a candidate who was able to exploit them.”

Along the same lines, if liberals and conservatives hold differing moral visions, not just about what makes a good government but about what makes a good life, what turned the relationship between left and right from competitive to mutually destructive?

Cultural differences, Gelfand continued, “have a certain logic — a rationale that makes good sense,” noting that “cultures that have threats need rules to coordinate to survive (think about how incredibly coordinated Japan is in response to natural disasters).

cultures that don’t have a lot of threat can afford to be more permissive and loose.”

The tight-loose concept, Gelfand argued,is an important framework to understand the rise of President Donald Trump and other leaders in Poland, Hungary, Italy, and France,

The gist is this: when people perceive threat — whether real or imagined, they want strong rules and autocratic leaders to help them survive

My research has found that within minutes of exposing study participants to false information about terrorist incidents, overpopulation, pathogen outbreaks and natural disasters, their minds tightened. They wanted stronger rules and punishments.

The South dominated the tight states: Mississippi, Alabama Arkansas, Oklahoma, Tennessee, Texas, Louisiana, Kentucky, South Carolina and North Carolina

Looseness, Gelfand posits, fosters tolerance, creativity and adaptability, along with such liabilities as social disorder, a lack of coordination and impulsive behavior.

If liberalism and conservatism have historically played a complementary role, each checking the other to constrain extremism, why are the left and right so destructively hostile to each other now, and why is the contemporary political system so polarized?

Gelfand writes that tightness encourages conscientiousness, social order and self-control on the plus side, along with close-mindedness, conventional thinking and cultural inertia on the minus side.

Niemi contended that sensitivity to various types of threat is a key factor in driving differences between the far left and far right.

She cited research thatfound 47 percent of the most extreme conservatives strongly endorsed the view that “The world is becoming a more and more dangerous place,” compared to 19 percent of the most extreme liberals

Conservatives and liberals, Niemi continued,see different things as threats — the nature of the threat and how it happens to stir one’s moral values (and their associated emotions) is a better clue to why liberals and conservatives react differently.

Unlike liberals, conservatives strongly endorse the binding moral values aimed at protecting groups and relationships. They judge transgressions involving personal and national betrayal, disobedience to authority, and disgusting or impure acts such as sexually or spiritually unchaste behavior as morally relevant and wrong.

Underlying these differences are competing sets of liberal and conservative moral priorities, with liberals placing more stress than conservatives on caring, kindness, fairness and rights — known among scholars as “individualizing values

conservatives focus more on loyalty, hierarchy, deference to authority, sanctity and a higher standard of disgust, known as “binding values.”

As a set, Niemi wrote, conservative binding values encompassthe values oriented around group preservation, are associated with judgments, decisions, and interpersonal orientations that sacrifice the welfare of individuals

Just as ecological factors differing from region to region over the globe produced different cultural values, ecological factors differed throughout the U.S. historically and today, producing our regional and state-level dimensions of culture and political patterns.

Niemi cited a paper she and Liane Young, a professor of psychology at Boston College, published in 2016, “When and Why We See Victims as Responsible: The Impact of Ideology on Attitudes Toward Victims,” which tested responses of men and women to descriptions of crimes including sexual assaults and robberies.

We measured moral values associated with unconditionally prohibiting harm (“individualizing values”) versus moral values associated with prohibiting behavior that destabilizes groups and relationships (“binding values”: loyalty, obedience to authority, and purity)

Increased endorsement of binding values predicted increased ratings of victims as contaminated, increased blame and responsibility attributed to victims, increased perceptions of victims’ (versus perpetrators’) behaviors as contributing to the outcome, and decreased focus on perpetrators.

For example, binding values are associated with Machiavellianism (e.g., status-seeking and lying, getting ahead by any means, 2013); victim derogation, blame, and beliefs that victims were causal contributors for a variety of harmful acts (2016, 2020); and a tendency to excuse transgressions of ingroup members with attributions to the situation rather than the person (2023).

What happened to people ecologically affected social-political developments, including the content of the rules people made and how they enforced them

Numerous factors potentially influence the evolution of liberalism and conservatism and other social-cultural differences, including geography, topography, catastrophic events, and subsistence styles

Joshua Hartshorne, who is also a professor of psychology at Boston College, took issue with the binding versus individualizing values theory as an explanation for the tendency of conservatives to blame victims:

I would guess that the reason conservatives are more likely to blame the victim has less to do with binding values and more to do with the just-world bias (the belief that good things happen to good people and bad things happen to bad people, therefore if a bad thing happened to you, you must be a bad person).

Belief in a just world, Hartshorne argued, is crucial for those seeking to protect the status quo:It seems psychologically necessary for anyone who wants to advocate for keeping things the way they are that the haves should keep on having, and the have-nots have got as much as they deserve. I don’t see how you could advocate for such a position while simultaneously viewing yourself as moral (and almost everyone believes that they themselves are moral) without also believing in the just world

Conversely, if you generally believe the world is not just, and you view yourself as a moral person, then you are likely to feel like you have an obligation to change things.

I asked Lene Aaroe, a political scientist at Aarhus University in Denmark, why the contemporary American political system is as polarized as it is now, given that the liberal-conservative schism is longstanding. What has happened to produce such intense hostility between left and right?

There is variation across countries in hostility between left and right. The United States is a particularly polarized case which calls for a contextual explanatio

A central explanation typically offered for the current situation in American politics is that partisanship and political ideology have developed into strong social identities where the mass public is increasingly sorted — along social, partisan, and ideological lines.

I then asked Aaroe why surveys find that conservatives are happier than liberals. “Some research,” she replied, “suggests that experiences of inequality constitute a larger psychological burden to liberals because it is more difficult for liberals to rationalize inequality as a phenomenon with positive consequences.”

Steven Pinker, a professor of psychology at Harvard, elaborated in an email on the link between conservatism and happiness:

t’s a combination of factors. Conservatives are likelier to be married, patriotic, and religious, all of which make people happier

They may be less aggrieved by the status quo, whereas liberals take on society’s problems as part of their own personal burdens. Liberals also place politics closer to their identity and striving for meaning and purpose, which is a recipe for frustration.

Some features of the woke faction of liberalism may make people unhappier: as Jon Haidt and Greg Lukianoff have suggested, wokeism is Cognitive Behavioral Therapy in reverse, urging upon people maladaptive mental habits such as catastrophizing, feeling like a victim of forces beyond one’s control, prioritizing emotions of hurt and anger over rational analysis, and dividing the world into allies and villains.

Why, I asked Pinker, would liberals and conservatives react differently — often very differently — to messages that highlight threat?

It may be liberals (or at least the social-justice wing) who are more sensitive to threats, such as white supremacy, climate change, and patriarchy; who may be likelier to moralize, seeing racism and transphobia in messages that others perceive as neutral; and being likelier to surrender to emotions like “harm” and “hurt.”

The authors used neural imaging to follow changes in the dorsomedial prefrontal cortex (known as DMPFC) as conservatives and liberals watched videos presenting strong positions, left and right, on immigration.

there are ways to persuade conservatives to support liberal initiatives and to persuade liberals to back conservative proposals:

While liberals tend to be more concerned with protecting vulnerable groups from harm and more concerned with equality and social justice than conservatives, conservatives tend to be more concerned with moral issues like group loyalty, respect for authority, purity and religious sanctity than liberals are. Because of these different moral commitments, we find that liberals and conservatives can be persuaded by quite different moral arguments

For example, we find that conservatives are more persuaded by a same-sex marriage appeal articulated in terms of group loyalty and patriotism, rather than equality and social justice.

“political arguments reframed to appeal to the moral values of those holding the opposing political position are typically more effective

We find support for these claims across six studies involving diverse political issues, including same-sex marriage, universal health care, military spending, and adopting English as the nation’s official language.”

In one test of persuadability on the right, Feinberg and Willer assigned some conservatives to read an editorial supporting universal health care as a matter of “fairness (health coverage is a basic human right)” or to read an editorial supporting health care as a matter of “purity (uninsured people means more unclean, infected, and diseased Americans).”

Conservatives who read the purity argument were much more supportive of health care than those who read the fairness case.

Liberals who read the fairness argument were substantially more supportive of military spending than those who read the loyalty and authority argument.

In “Conservative and Liberal Attitudes Drive Polarized Neural Responses to Political Content,” Willer, Yuan Chang Leong of the University of Chicago, Janice Chen of Johns Hopkins and Jamil Zaki of Stanford address the question of how partisan biases are encoded in the brain:

society. How do such biases arise in the brain? We measured the neural activity of participants watching videos related to immigration policy. Despite watching the same videos, conservative and liberal participants exhibited divergent neural responses. This “neural polarization” between groups occurred in a brain area associated with the interpretation of narrative content and intensified in response to language associated with risk, emotion, and morality. Furthermore, polarized neural responses predicted attitude change in response to the videos.

The four authors argue that their “findings suggest that biased processing in the brain drives divergent interpretations of political information and subsequent attitude polarization.” These results, they continue, “shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.”

While liberals and conservatives, guided by different sets of moral values, may make agreement on specific policies difficult, that does not necessarily preclude consensus.

or each video,” they write,participants with DMPFC activity time courses more similar to that of conservative-leaning participants became more likely to support the conservative positio

Conversely, those with DMPFC activity time courses more similar to that of liberal-leaning participants became more likely to support the liberal position. These results suggest that divergent interpretations of the same information are associated with increased attitude polarizatio

Together, our findings describe a neural basis for partisan biases in processing political information and their effects on attitude change.

Describing their neuroimaging method, the authors point out that theysearched for evidence of “neural polarization” activity in the brain that diverges between people who hold liberal versus conservative political attitudes. Neural polarization was observed in the dorsomedial prefrontal cortex (DMPFC), a brain region associated with the interpretation of narrative content.

The question is whether the political polarization that we are witnessing now proves to be a core, encoded aspect of the human mind, difficult to overcome — as Leong, Chen, Zaki and Willer sugges

— or whether, with our increased knowledge of the neural basis of partisan and other biases, we will find more effective ways to manage these most dangerous of human predispositions.

Migrants are in politicians’ cross hairs, threatened with deportation and reduced support.

And the country’s commitment to fighting antisemitism seems not only to be failing but also to have given rise to an outpouring of anti-Muslim sentiment.

The truth is that Germany never fully deserved its vaunted reputation. The export-led economy depended on a large low-wage sector and the country’s position in the European Union.

The far right — ensconced in parts of the state — never went away, and the celebrated Willkommenskultur, short lived in any case, couldn’t conceal enduring xenophobia and suspicion about foreigners.

The culture of remembrance and historical reckoning, too, was far from perfect

Even so, the sudden coarsening of public life in the service of a warped sense of national identity is striking. Germany, supposed model of fair-minded moderation, has become mean.

the government’s habit of conflating criticism of Israel with antisemitism has had some disturbing effects. Most notably, it has created an atmosphere where advocacy for Palestinian rights or a cease-fire in Gaza is seen as suspect, running afoul of the state-mandated position

The police, for example, have cracked down on pro-Palestinian protests in several cities and outright banned numerous demonstrations.

politicians, seizing on some evidence of antisemitic displays at pro-Palestinian protests to link Muslims and migrants with antisemitism, have taken the opportunity to advance an anti-migrant agenda

When Mr. Scholz was asked about antisemitism among people “with Arab roots” in an October interview, he said Germany needed to sort out more precisely who is allowed to come into the country and who is not. “We are limiting irregular migration,” Mr. Scholz pronounced, before adding a little later, “We must finally deport on a large scale.”

More spending cuts are expected. In an economy on the cusp of recession — Germany is the only country among Group of 7 nations not expected to register growth in 2023 — this is bad news for Germans, who, according to a recent study, are predominantly worried about living expenses, increasing rents, tax hikes and cuts to benefits.

everal other high-ranking politicians have also pushed the need for stricter border controls in the aftermath of Oct. 7. Friedrich Merz, leader of the opposition Christian Democrats, spoke out against taking in refugees from Gaza, claiming that Germany already has “enough antisemitic young men in the country.”

In early November, after months of intense discussions, the federal government and the 16 state governors agreed on stricter measures to curb the number of migrants entering the country. Asylum seekers now receive less cash and have to wait twice as long to get on welfare, taking even more autonomy away from their lives. According to the new plan, Germany will also extend its border checks, speed up asylum procedures and look into the idea of offshoring asylum centers.

Worryingly, antisemitic incidents have been on the rise in recent weeks

it is troubling that Germany, of all places, should frame antisemitism as an imported problem. Crime statistics show that a vast majority of antisemitic crimes are committed by right-wing extremists and not by Islamists, let alone migrants or Muslims.

Germany’s leaders, aided by major media figures, are using the fight against antisemitism as a pretext to encourage racist resentment and anti-migrant sentiment.

Alternative for Germany, which has pulled the political center of gravity to the right since its formation in 2013, has never been stronger. Polling at over 20 percent, the party and its concerns, once fringe, are firmly mainstream. Questions of national identity and immigration dominate political discussion, in keeping with a broader rise of nativism across Europe.

The country’s anti-migrant turn is often justified in terms of economic concerns.

Opponents of immigration point to the underfunding of schools and hospitals, the lack of affordable housing, the miserable public transport and the general decline of the domestic economy.

German infrastructure is indeed in crisis. But this has little to do with immigration and everything to do with austerity policies that have been in place for the past two decades.

Central to those policies is the so-called debt brake. Enshrined in the German Constitution in 2009, it restricts the annual public deficit to 0.35 percent of gross domestic product, ensuring strict limits on spending.

The effects have been immediate: Mr. Lindner announced an early end to a price cap on energy bills, making it likely that German citizens will have to pay more for their heating in the coming year.

Christian Lindner, the finance minister and head of the center-right Free Democratic Party, called for a fundamental change in immigration policy to “reduce the appeal of the German welfare state.”

It’s bad news for the government, too. The coalition, composed of the Social Democrats, Greens and Free Democrats, came to office in 2021 with a mandate to modernize the country and lead it in a progressive direction

Instead, with programs of fiscal restriction and stances of social reaction, Germany’s leaders are only serving the far-right party they claim to want to keep at bay.

Terrorism, public health, and police violence are all life-and-death issues, and all involve the state, so they’re more consequential than the criticism, shunning, and loss of professional opportunities associated with cancel culture. But that doesn’t mean the latter isn’t a problem.

We can, and should, care about more than one thing at a time, and many things that aren’t the worst problem deserve attention.

Nevertheless, it’s important to assess problems accurately.

Michael Hobbes calls all this worrying about wokeness a “moral panic.” That’s a term some use online to wave away serious concerns, but Hobbes uses it the way sociologist Stanley Cohen did in the 1970s, as a phenomenon where something becomes “defined as a threat to societal values and interests” based on media accounts that “exaggerate the seriousness, extent, typicality and/or inevitability of harm.”

The point here is not that stranger abductions never happened, but that they didn’t happen nearly as much as the media, concerned parents, and lawmakers thought. And because stranger kidnappings were not a national crisis, but treated as one, the “solution” made things worse.

Along similar lines, Hobbes argues that anti-woke alarm-bell-ringing relies on a relatively small number of oft-repeated anecdotes. Some don’t stand up to scrutiny, and some of those that do are low-stakes. The resulting moral panic fuels, among other things, a wave of red state legislation aimed at banning “critical race theory” that uses vague language and effectively cracks down on teaching about racism in American history.

For that, we should look to data, and here again the problem looks smaller than anti-woke liberals make it out to be

In the universe of cancel culture cases, I find more incidents concerning than Hobbes and fewer concerning than Young, but “this one incident wasn’t actually bad” vs. “yes it really was” doesn’t answer the question about size and scope. It doesn’t tell us what, if anything, society should do about it.

In Liberal Currents, Adam Gurri cites the Foundation for Individual Rights in Education (FIRE), which documented 426 “targeting incidents involving scholars at public and private American institutions of higher education” since 2015 and 492 “disinvitation attempts” since 1998

The organization Canceled People lists 217 cases of “cancellation” since 1991, while the National Association of Scholars (NAS) lists 194 cancellations in academia since 2004 (plus two in the 20th century).

Based on these numbers, Gurri concludes, “If any other problem in social life was occurring at this frequency and at this scale, we would consider it effectively solved.”

There are nearly 4,000 colleges and universities in the United States. U.S. News’ 2021 rankings of the best schools lists 1,452. Using that smaller number and NAS’s figure of 194 academic cancellations since 2004, the chance of a college or university experiencing a cancellation in a given year is less than 0.8 percent.

There are some concerning cases in the NAS database too, in which professors were fired for actions that should be covered under a basic principle of academic freedom — for example, reading aloud a Mark Twain passage that included a racial slur, even after giving students advance notice — so this isn’t a total non-issue. But the number of low stakes and relatively unobjectionable cases means the risk is lower than 0.8 percent (and it’s even lower than that, since NAS includes Canada and my denominator is ranked schools in the United States).

Similarly, FIRE classifies about 30 percent of the attempted disinvitations in its database as from the right. About 60 percent are from the left — the other 10 percent N/A — so if you want to argue that the left does this more, you’ve got some evidence. But still, the number of cases from the left is lower than the total. And more than half of FIRE’s attempted disinvitations did not result in anyone getting disinvited.

Using U.S. News’ ranked schools as the denominator, the chance of left-wing protestors trying to get a speaker disinvited at a college or university in a given year is about 0.5 percent. The chance of an actual disinvitation is less than 0.25 percent. And that’s in the entire school. To put this in perspective, my political science department alone hosts speakers most weeks of the semester.

Two things jump out here:

Bari Weiss and Anne Applebaum both cite a Cato study purporting to show this effect:

even if we assume these databases capture a fraction of actual instances — which would be surprising, given the media attention on this topic, but even so — the data does not show an illiberal left-wing movement in control of academia.

The number agreeing that the political climate prevents them from saying things they believe ranges from 42% to 77%, which is high across political views. That suggests self-censorship is, to a significant degree, a factor of the political, cultural, and technological environment, rather than caused by any particular ideology.

Conservatives report self-censoring more than liberals do.

The same study shows that the biggest increase in self-censorship from 2017 to 2020 was among strong liberals (+12), while strong conservatives increased the least (+1).

If this data told a story of ascendent Maoists suppressing conservative speech, it would probably be the opposite, with the left becoming more confident of expressing their views — on race, gender, etc. — while the right becomes disproportionately more fearful. Culture warriors fixate on wokeness, but when asked about the political climate, many Americans likely thought about Trumpism

Nevertheless, this data does show conservatives are more likely to say the political climate prevents them from expressing their beliefs. But what it doesn’t show is which beliefs or why.

Self-censoring can be a problem, but also not. The adage “do not discuss politics or religion in general company” goes back to at least 1879. If someone today is too scared to say “Robin DiAngelo’s conception of ‘white fragility’ does not stand up to logical scrutiny,” that’s bad. If they’re too scared to shout racial slurs at minorities, that isn’t. A lot depends on the content of the speech.

When I was a teenager in the 1990s, anti-gay slurs were common insults among boys, and tough-guy talk in movies. Now it’s a lot less common, one of the things pushed out of polite society, like the n-word, Holocaust denial, and sexual harassment. I think that’s a positive.

Another problem with the anti-woke interpretation of the Cato study is media constantly tells conservatives they’re under dire threat.

Fox News, including Tucker Carlson (the most-watched show on basic cable), Ben Shapiro and Dan Bongino (frequently among the most-shared on Facebook), and other right-wing outlets devote tons of coverage to cancel culture, riling up conservatives with hyperbolic claims that people are coming for them

Anti-woke liberals in prestigious mainstream outlets tell them it’s the Cultural Revolution

Then a survey asks if the political climate prevents them from saying what they believe, and, primed by media, they say yes.

With so many writers on the anti-woke beat, it’s not especially plausible that we’re missing many cases of transgender servers getting people canceled for using the wrong pronoun in coffee shops to the point that everyone who isn’t fully comfortable with the terminology should live in fear. By overstating the threat of cancellation and the power of woke activists, anti-woke liberals are chilling speech they aim to protect.

a requirement to both-sides the Holocaust is a plausible read of the legal text. It’s an unsurprising result of empowering the state to suppress ideas in an environment with bad faith culture warriors, such as Chris Rufo and James Lindsay, advocating state censorship and deliberately stoking panic to get it.

Texas, Florida, and other states trying to suppress unwanted ideas in both K-12 and higher ed isn’t the Cultural Revolution either — no state-sanctioned mass violence here — but it’s coming from government, making it a bigger threat to speech and academic freedom.

To put this in perspective, antiracist guru Ibram X. Kendi has called for an “anti-racist Constitutional amendment,” which would “make unconstitutional racial inequity over a certain threshold, as well as racist ideas by public officials,” and establish a Department of Anti-Racism to enforce it. It’s a terrible proposal that would repeal the First Amendment and get the state heavily involved in policing speech (which, even if well-intentioned, comes with serious risks of abuse).

It also doesn’t stand the slightest chance of happening.

It’s fair to characterize this article as anti-anti-woke. And I usually don’t like anti-anti- arguments, especially anti-anti-Trump (because it’s effectively pro). But in this case I’m doing it because I reject the binary.

American politics is often binary.

Culture is not. It’s an ever-changing mishmash, with a large variety of influential participants

There have been unmistakable changes in American culture — Western culture, really — regarding race and gender, but there are way more than two sides to that. You don’t have to be woke or anti-woke. It’s not a political campaign or a war. You can think all sorts of things, mixing and matching from these ideas and others.

I won’t say “this is trivial” nor “this stuff is great,” because I don’t think either. At least not if “this” means uncompromising Maoists seeking domination.

I think that’s bad, but it’s not especially common. It’s not fiction — I’m online a lot, I have feet in both media and academia, I’ve seen it too — but, importantly, it’s not in control

I think government censorship is inherently more concerning than private censorship, and that we can’t sufficiently counter the push for state idea-suppression without countering the overstated fears that rationalize it.

I think a lot of the private censorship problem can be addressed by executives and administrators — the ones who actually have power over businesses and universities — showing a bit of spine. Don’t fold at the first sign of protest. Take some time to look into it yourself, and make a judgment call on whether discipline is merited and necessary. Often, the activist mob will move on in a few days anyway.

I think that, with so much of the conversation focusing on extremes, people often miss when administrators do this.

I think violence is physical, and that while speech can be quite harmful, it’s better to think of these two things as categorically different than to insist harmful speech is literally violence.

at a baseline, treating people as equals means respecting who they say they are. The vast majority are not edge cases like a competitive athlete, but regular people trying to live their lives. Let them use the bathroom in peace.

I think the argument that racism and other forms of bigotry operate at a systemic or institutional, in addition to individual, level is insightful, intuitive, and empirically supported. We can improve people’s lives by taking that into account when crafting laws, policies, and practices.

I think identity and societal structures shape people’s lives (whether they want it to or not) but they’re far from the only factors. Treating them as the only, or even predominant, factor essentializes more than it empowers.

I think transgender and non-binary people have a convincing case for equality. I don’t think that points to clear answers on every question—what’s the point of gender segregated sports?

I think free association is an essential value too. Which inherently includes the right of disassociation.

I think these situations often fall into a gray area, and businesses should be able to make their own judgment calls about personnel, since companies have a reasonable interest in protecting their brand.

I think free speech is an essential value, not just at the legal level, but culturally as well. I think people who would scrap it, from crusading antiracists to social conservatives pining for Viktor Orban’s Hungary, have a naively utopian sense of how that would go (both in general and for them specifically). Getting the state involved in speech suppression is a bad idea.

I think America’s founding was a big step forward for government and individual liberty, and early America was a deeply racist, bigoted place that needed Amendments (13-15; 19), Civil Rights Acts, and landmark court cases to become a liberal democracy. I don’t think it’s hard to hold both of those in your head at the same time.

I think students learning the unvarnished truth about America’s racist past is good, and that teaching students they are personally responsible for the sins of the past is not.

I think synthesis of these cultural forces is both desirable and possible. Way more people think both that bigotry is bad and individual freedom is good than online arguments lead you to believe.

I don’t think the sides are as far apart as they think.

I think we should disaggregate cancel culture and left-wing identity politics. Cancellation should be understood as an internet phenomenon.

If it ever was just something the left does, it isn’t anymore.

I think a lot of us could agree that social media mobbing and professional media attention on minor incidents is wrong, especially as part of a campaign to get someone fired. In general, disproportionally severe social and professional sanctions is a problem, no matter the alleged cause.

I think most anti-woke liberals really do want to defend free speech and academic freedom. But I don’t think their panic-stoking hyperbole is helping.

China’s drop was much much bigger; the Japan of the 80s was never the export machine people believed it to be. Both countries turned to investment in real estate and infrastructure as a replacement growth driver — although again, China did this much more than Japan did. Essentially, China did all the the things we typically think of Japan as having done 25 years earlier, but much more than Japan actually did them.

Yes, for those who were wondering, this does look a little bit like what happened to Japan in the 1990s

Already the country is not growing much faster than the G7, and as the ongoing real estate bust weighs on the economy, even that small difference may now be gone. The country’s surging auto industry is a bright spot, but won’t be big enough to rescue the economy from the evaporation of its primary growth driver.

Even if it manages to climb up to 40%, that’s still a fairly disappointing result — South Korea is at 71% and Japan at 65%

a re-acceleration would require a massive burst of productivity growth, which just seems unlikely.

That means China’s catch-up growth only took it to 30% of U.S. per capita GDP (PPP)

There’s one main argument that people make for a quick Chinese decline: rapid aging. But while I don’t want to wave this away, I don’t think it’s going to be as big a deal as many believe

This is another example of China’s peak being both awe-inspiring and strangely disappointing at the same time.

Now that China has hit its peak, will it decline? And if so, how much and how fast?

it seems likely that China’s growth will now slow to developed-country levels, or slightly higher, without much prospect for a sustained re-acceleration

when people contemplate Chinese decline, they’re not asking whether its economy will shrink; they’re asking whether its relative economic dominance and geopolitical importance will decrease.

If we just casually pattern-match on history, the answer would probably be “not for a long time”. Most powerful countries seem to peak and then plateau. Britain ruled the waves for a century.

U.S. relative power and economic dominance peaked in the 1950s, but it didn’t really start declining until the 2000s

Japan and Germany had their military power smashed in WW2, but remained economic heavyweights for many decades afterwards.

When the Roman Empire declined, it got a lot poorer. But in the modern economy, countries that decline in relative terms, and in geopolitical power, often get richer

he total fertility rate has been low since even before the one-child policy was implemented, but recently it has taken a nose-dive. Two years ago, the UN put it at 1.16, which is 40% lower than the U.S. and 22% lower than Europe

The country’s total population only started shrinking this year, but its young population started falling sharply 20 years ago, due to the echo of low fertility in the 80s. The most common age for a Chinese person is now about 50 years old, with another peak at 35:

The first reason is that power is relative, and China’s rivals have demographic issues of their own. The U.S., Europe, India and Japan all have higher fertility than China, but still below replacement level

demographics aren’t actually going to force Chinese power or wealth into rapid decline over the next few decades.

third of all, evidence suggests that population aging is really more of a persistent drag than a crisis or disaster.

Second, demographics won’t take away China’s biggest economic advantage, which is clustering and agglomeration effects. Asia is the world’s electronics manufacturing hub. It’s also by far the most populous region in the world, giving it the biggest potential market size

China will act as a key hub for that region, in terms of trade, supply chains, investment, and so on. China is shrinking, but Asia is not

As a result, there are suddenly many fewer Chinese people able to bear children, which is why the actual number of births in China has fallen by almost half since 2016:

we’d find that every percentage point of the senior population share that China gains relative to other countries might reduce its relative economic performance by about 1.15%. That’s not a huge number.

Now, if we look at the research, we find some estimates that are much larger than this — for example, Ozimek et al. (2018) look at specific industries and specific U.S. states, and find an effect on productivity that’s three times as large as the total effect on growth that I just eyeballed above. Maestas et al. (2022) look at U.S. states, and also find a larger effect. But Acemoglu and Restrepo (2017) look across countries and find no effect at all.

On top of that, there are plenty of things a country can do to mitigate the effects of aging. One is automation. China is automating at breakneck speed,

A second is having old people work longer; China, which now has higher life expectancy than the U.S., is well-positioned to do this.

Finally, aging will prompt China to do something it really needs to do anyway: build a world class health care system

this would help rectify the internal imbalances that Michael Pettis always talks about, shifting output from low-productivity real estate investment toward consumption.

if not aging, the only other big dangers to China are war and climate change.

To realize its full potential, Altasia will need integration — it will need some way to get Japanese and Korean and Taiwanese investment and technology to the vast labor forces of India, Indonesia, and the rest

the most likely outcome is that China sits at or near its current peak of wealth, power and importance through the middle of this century at least.

Altasia has more people and arguably more technical expertise than China. And it’s the only alternative location for the Asian electronics supercluster.

War was the big mistake that Germany made a century ago, so let’s hope China doesn’t follow in its footsteps.

The story of whether and how that complex web of investment, tech transfer, and trade develops will be the next great story of globalization.

But I think the very complexity of Altasia will lead to its own sort of adventure and excitement.

for Western companies looking for new markets, Altasia will potentially be more exciting than China ever was. The Chinese market delivered riches to some, but the government banned some products (especially internet services) and stole the technology used to make others. Ultimately, China’s billion consumers turned out to be a mirage for many. The economies and societies of Altasia, in comparison, are much more open to foreign products.

There’s plenty of blame to go around, involving Democrats as well as Republicans, but Trump in particular “recklessly squandered lives,” in the words of an unusual editorial this month in the New England Journal of Medicine. Death certificates may record the coronavirus as the cause of death, but in a larger sense vast numbers of Americans died because their government was incompetent.

As many Americans are dying every 10 days of Covid-19 as U.S. troops died during 19 years of war in Iraq and Afghanistan

The paradox is that a year ago, the United States seemed particularly well positioned to handle this kind of crisis. A 324-page study by Johns Hopkins found last October that the United States was the country best prepared for a pandemic.

Then there’s an immeasurable cost in soft power as the United States is humbled before the world.

“It’s really sad to see the U.S. presidency fall from being the champion of global health to being the laughingstock of the world,”

in terms of destruction of American lives, treasure and well-being, this pandemic may be the greatest failure of governance in the United States since the Vietnam War.

the economists David Cutler and Lawrence Summers estimate that the economic cost of the pandemic in the United States will be $16 trillion, or about $125,000 per American household — far more than the median family’s net worth.

It’s true that the Obama administration did not do enough to refill the national stockpile with N95 masks, but Republicans in Congress wouldn’t provide even the modest sums that Obama requested for replenishment. And the Trump administration itself did nothing in its first three years to rebuild stockpiles.

The Obama administration updated this playbook and in the presidential transition in 2016, Obama aides cautioned the Trump administration that one of the big risks to national security was a contagion. Private experts repeated similar warnings. “Of all the things that could kill 10 million people or more, by far the most likely is an epidemic,” Bill Gates warned in 2015.

Credit for that goes to President George W. Bush, who in the summer of 2005 read an advance copy of “The Great Influenza,” a history of the 1918 flu pandemic. Shaken, Bush pushed aides to develop a strategy to prepare for another great contagion, and the result was an excellent 396-page playbook for managing such a health crisis.

Trump argues that no one could have anticipated the pandemic, but it’s what Bush warned about, what Obama aides tried to tell their successors about, and what Joe Biden referred to in a blunt tweet in October 2019 lamenting Trump’s cuts to health security programs and adding: “We are not prepared for a pandemic.”

When the health commission of Wuhan, China, announced on Dec. 31 that it had identified 27 cases of a puzzling pneumonia, Taiwan acted with lightning speed. Concerned that this might be an outbreak of SARS, Taiwan dispatched health inspectors to board flights arriving from Wuhan and screen passengers before allowing them to disembark. Anyone showing signs of ill health was quarantined.

If either China or the rest of the world had shown the same urgency, the pandemic might never have happened.

In hindsight, two points seem clear: First, China initially covered up the scale of the outbreak. Second, even so, the United States and other countries had enough information to act as Taiwan did. The first two countries to impose travel restrictions on China were North Korea and the Marshall Islands, neither of which had inside information.

That first half of January represents a huge missed opportunity for the world. If the United States, the World Health Organization and the world media had raised enough questions and pressed China, then perhaps the Chinese central government would have intervened in Wuhan earlier. And if Wuhan had been locked down just two weeks earlier, it’s conceivable that this entire global catastrophe could have been averted.

the C.D.C. devised a faulty test, and turf wars in the federal government prevented the use of other tests. South Korea, Germany and other countries quickly developed tests that did work, and these were distributed around the world. Sierra Leone in West Africa had effective tests before the United States did.

It’s true that local politicians, Democrats and Republicans alike, made disastrous decisions, as when Mayor Bill de Blasio of New York City urged people in March to “get out on the town despite coronavirus.” But local officials erred in part because of the failure of testing: Without tests, they didn’t know what they faced.

t’s unfair to blame the testing catastrophe entirely on Trump, for the failures unfolded several pay grades below him. Partly that’s because Trump appointees, like Robert Redfield, director of the C.D.C., simply aren’t the A team.

In any case, presidents set priorities for lower officials. If Trump had pushed aides as hard to get accurate tests as he pushed to repel refugees and migrants, then America almost certainly would have had an effective test by the beginning of February and tens of thousands of lives would have been saved.

Still, testing isn’t essential if a country gets backup steps right. Japan is a densely populated country that did not test much and yet has only 2 percent as many deaths per capita as the United States. One reason is that Japanese have long embraced face masks, which Dr. Redfield has noted can be at least as effective as a vaccine in fighting the pandemic. A country doesn’t have to do everything, if it does some things right.

Trump’s missteps arose in part because he channeled an anti-intellectual current that runs deep in the United States, as he sidelined scientific experts and responded to the virus with a sunny optimism apparently meant to bolster the financial markets.

Yet in retrospect, Trump did almost everything wrong. He discouraged mask wearing. The administration never rolled out contact tracing, missed opportunities to isolate the infected and exposed, didn’t adequately protect nursing homes, issued advice that confused the issues more than clarified them, and handed responsibilities to states and localities that were unprepared to act.

The false reassurances and dithering were deadly. One study found that if the United States had simply imposed the same lockdowns just two weeks earlier, 83 percent of the deaths in the early months could have been prevented.

A basic principle of public health is the primacy of accurate communications based on the best science. Chancellor Angela Merkel of Germany, who holds a doctorate in physics, is the global champion of that approach

Trump was the opposite, sowing confusion and conspiracy theories; a Cornell study found that “the President of the United States was likely the largest driver of the Covid-19 misinformation.”

A conservative commentariat echoed Trump in downplaying the virus and deriding efforts to stay safe.

A University of Chicago study found that watching the Sean Hannity program correlated to less social distancing, so watching Fox News may well have been lethal to some of its fans.

Americans have often pointed to the Soviet Union as a place where ideology trumped science, with disastrous results. Stalin backed Trofim Lysenko, an agricultural pseudoscientist who was an ardent Communist but scorned genetics — and whose zealous incompetence helped cause famines in the Soviet Union. Later, in the 1980s, Soviet leaders were troubled by data showing falling life expectancy — so they banned the publication of mortality statistics

It was in the same spirit that Trump opposed testing for the coronavirus in the hope of holding down the number of reported cases.

Most striking, Trump still has never developed a comprehensive plan to fight Covid-19. His “strategy” was to downplay the virus and resist business closures, in an effort to keep the economy roaring — his best argument for re-election.

This failed. The best way to protect the economy was to control the virus, not to ignore it, and the spread of Covid-19 caused economic dislocations that devastated even homes where no one was infected.

Eight million Americans have slipped into poverty since May, a Columbia University study found, and about one in seven households with children have reported to the census that they didn’t have enough food to eat in the last seven days.

More than 40 percent of adults reported in June that they were struggling with mental health, and 13 percent have begun or increased substance abuse, a C.D.C. study found

More than one-quarter of young adults said they have seriously contemplated suicide

So in what is arguably the richest country in the history of the world, political malpractice has resulted in a pandemic of infectious disease followed by pandemics of poverty, mental illness, addiction and hunger.

The rejection of science has also exacerbated polarization and tribalism

An old school friend shared this conspiracy theory on Facebook:Create a VIRUS to scare people. Place them in quarantine. Count the number of dead every second of every day in every news headline. Close all businesses …. Mask people. Dehumanize them. Close temples and churches …. Empty the prisons because of the virus and fill the streets with criminals. Send in Antifa to vandalize property as if they are freedom fighters. Undermine the law. Loot …. And, in an election year, have Democrats blame all of it on the President. If you love America, our Constitution, and the Rule of Law, get ready to fight for them.

During World War II, American soldiers died at a rate of 9,200 a month, less than one-third the pace of deaths from this pandemic, but the United States responded with a massive mobilization

Yet today we can’t even churn out enough face masks; a poll of nurses in late July and early August found that one-third lacked enough N95 masks

Trump and his allies have even argued against mobilization. “Don’t be afraid of Covid,” Trump tweeted this month. “Don’t let it dominate your life.”

It didn’t have to be this way. If the U.S. had worked harder and held the per capita mortality rate down to the level of, say, Germany, we could have saved more than 170,000 lives

And if the U.S. had responded urgently and deftly enough to achieve Taiwan’s death rate, fewer than 100 Americans would have died from the virus.

“It is a slaughter,” Dr. William Foege, a legendary epidemiologist who once ran the C.D.C., wrote to Dr. Redfield. Dr. Foege predicted that public health textbooks would study America’s response to Covid-19 not as a model of A-plus work but as an example of what not to do.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

there is a world of content out there that has not been watermarked, which is done by adding imperceptible information to a digital file so that its provenance can be traced. Once watermarking at creation becomes widespread, and people adapt to distrust content that is not watermarked, then everything produced before that point in time can be much more easily called into question.

countering them is much harder when the cost of creating near-perfect fakes has been radically reduced.

There are many examples of how economic and political powers manipulated the historical record to their own ends. Stalin purged disloyal comrades from history by executing them — and then altering photographic records to make it appear as if they never existed

Slovenia, upon becoming an independent country in 1992, “erased” over 18,000 people from the registry of residents — mainly members of the Roma minority and other ethnic non-Slovenes. In many cases, the government destroyed their physical records, leading to their loss of homes, pensions, and access to other services, according to a 2003 report by the Council of Europe Commissioner for Human Rights.

The infamous Protocols of the Elders of Zion, first published in a Russian newspaper in 1903, purported to be meeting minutes from a Jewish conspiracy to control the world. First discredited in August 1921, as a forgery plagiarized from multiple unrelated sources, the Protocols featured prominently in Nazi propaganda, and have long been used to justify antisemitic violence, including a citation in Article 32 of Hamas’s 1988 founding Covenant.

In 1924, the Zinoviev Letter, said to be a secret communiqué from the head of the Communist International in Moscow to the Communist Party of Great Britain to mobilize support for normalizing relations with the Soviet Union, was published by The Daily Mail four days before a general election. The resulting scandal may have cost Labour the election.

As it becomes easier to generate historical disinformation, and as the sheer volume of digital fakes explodes, the opportunity will become available to reshape history, or at least to call our current understanding of it into question.

Decades later Operation Infektion — a Soviet disinformation campaign — used forged documents to spread the idea that the United States had invented H.I.V., the virus that causes AIDS, as a biological weapon.

Fortunately, a path forward has been laid by the same companies that created the risk.

In indexing a large share of the world’s digital media to train their models, the A.I. companies have effectively created systems and databases that will soon contain all of humankind’s digitally recorded content, or at least a meaningful approximation of it.

They could start work today to record watermarked versions of these primary documents, which include newspaper archives and a wide range of other sources, so that subsequent forgeries are instantly detectable.

many of the intellectual property concerns around providing a searchable online archive do not apply to creating watermarked and time-stamped versions of documents, because those versions need not be made publicly available to serve their purpose. One can compare a claimed document to the recorded archive by using a mathematical transformation of the document known as a “hash,” the same technique the Global Internet Forum to Counter Terrorism, uses to help companies screen for known terrorist content.

creating verified records of historical documents can be valuable for the large A.I. companies. New research suggests that when A.I. models are trained on A.I.-generated data, their performance quickly degrades. Thus separating what is actually part of the historical record from newly created “facts” may be critical.

Preserving the past will also mean preserving the training data, the associated tools that operate on it and even the environment that the tools were run in.

Such a vellum will be a powerful tool. It can help companies to build better models, by enabling them to analyze what data to include to get the best content, and help regulators to audit bias and harmful content in the models

With respect to crime, poverty and homelessness, Brown argued,One thing that may occur is that disinvestment in city downtowns will alter the spatial distribution of these elements in cities — i.e. in which neighborhoods or areas of a city is crime more likely, and homelessness more visible. Urban downtowns are often policed such that these visible elements of poverty are pushed to other parts of the city where they will not interfere with commercial activities. But absent these activities, there may be less political pressure to maintain these areas. This is not to say that the overall crime rate or homelessness levels will necessarily increase, but their spatial redistribution may further alter the trajectory of commercial downtowns — and the perception of city crime in the broader public.

“The more dramatic effects on urban geography,” Brown continued,may be how this changes cities in terms of economic and racial segregation. One urban trend from the last couple of decades is young white middle- and upper-class people living in cities at higher rates than previous generations. But if these groups become less likely to live in cities, leaving a poorer, more disproportionately minority population, this will make metropolitan regions more polarized by race/class.

the damage that even the perception of rising crime can inflict on Democrats in a Nov. 27 article, “Meet the Voters Who Fueled New York’s Seismic Tilt Toward the G.O.P.”: “From Long Island to the Lower Hudson Valley, Republicans running predominantly on crime swept five of six suburban congressional seats, including three that President Biden won handily that encompass some of the nation’s most affluent, well-educated commuter towns.

In big cities like New York and San Francisco we estimate large drops in retail spending because office workers are now coming into city centers typically 2.5 rather than 5 days a week. This is reducing business activity by billions of dollars — less lunches, drinks, dinners and shopping by office workers. This will reduce city hall tax revenues.

Public transit systems are facing massive permanent shortfalls as the surge in working from home cuts their revenues but has little impact on costs (as subway systems are mostly a fixed cost. This is leading to a permanent 30 percent drop in transit revenues on the New York Subway, San Francisco Bart, etc.

These difficulties for cities will not go away anytime soon. Bloom provided data showing strong economic incentives for both corporations and their employees to continue the work-from-home revolution if their jobs allow it:

First, “Saved commute time working from home averages about 70 minutes a day, of which about 40 percent (30 minutes) goes into extra work.” Second, “Research finds hybrid working from home increases average productivity around 5 percent and this is growing.” And third, “Employees also really value hybrid working from home, at about the same as an 8 percent pay increase on average.

three other experts in real estate economics, Arpit Gupta, of N.Y.U.’s Stern School of Business, Vrinda Mittal, both of the Columbia Business School, and Van Nieuwerburgh. They anticipate disaster in their September 2022 paper, “Work From Home and the Office Real Estate Apocalypse.”

“Our research,” Gupta wrote by email,emphasizes the possibility of an ‘urban doom loop’ by which decline of work in the center business district results in less foot traffic and consumption, which adversely affects the urban core in a variety of ways (less eyes on the street, so more crime; less consumption; less commuting) thereby lowering municipal revenues, and also making it more challenging to provide public goods and services absent tax increases. These challenges will predominantly hit blue cities in the coming years.

We find a 45 percent decline in office values in 2020 and 39 percent in the longer run, the latter representing a $453 billion value destruction.”

Extrapolating to all properties in the United States, Gupta, Mittal and Van Nieuwerburgh write, the “total decline in commercial office valuation might be around $518.71 billion in the short-run and $453.64 billion in the long-run.”

the share of real estate taxes in N.Y.C.’s budget was 53 percent in 2020, 24 percent of which comes from office and retail property taxes. Given budget balance requirements, the fiscal hole left by declining central business district office and retail tax revenues would need to be plugged by raising tax rates or cutting government spending.

Since March 2020, Manhattan has lost 200,000 households, the most of any county in the U.S. Brooklyn (-88,000) and Queens (-51,000) also appear in the bottom 10. The cities of Chicago (-75,000), San Francisco (-67,000), Los Angeles (-64,000 for the city and -136,000 for the county), Washington DC (-33,000), Seattle (-31,500), Houston (-31,000), and Boston (-25,000) make up the rest of the bottom 10.

Prior to the pandemic, these ecosystems were designed to function based on huge surges in their daytime population from commuters and tourists. The shock of the sudden loss of a big chunk of this population caused a big disruption in the ecosystem.

Just as the pandemic has caused a surge in telework, Loh wrote, “it also caused a huge surge in unsheltered homelessness because of existing flaws in America’s housing system, the end of federally-funded relief measures, a mental health care crisis, and the failure of policies of isolation and confinement to solve the pre-existing homelessness crisis.”

The upshot, Loh continued,is that both the visibility and ratio of people in crisis relative to those engaged in commerce (whether working or shopping) has changed in a lot of U.S. downtowns, which has a big impact on how being downtown ‘feels’ and thus perceptions of downtown.

The nation, Glaeser continued, isat an unusual confluence of trends which poses dangers for cities similar to those experienced in the 1970s. Event#1 is the rise of Zoom, which makes relocation easier even if it doesn’t mean that face-to-face is going away. Event#2 is a hunger to deal with past injustices, including police brutality, mass incarceration, high housing costs and limited upward mobility for the children of the poor.

Progressive mayors, according to Glaeser,have a natural hunger to deal with these problems at the local level, but if they try to right injustices by imposing costs on businesses and the rich, then those taxpayers will just leave. I certainly remember New York and Detroit in the 1960s and 1970s, where the dreams of progressive mayors like John Lindsay and Jerome Patrick Cavanagh ran into fiscal realities.

Richard Florida, a professor of economic analysis and policy at the University of Toronto, stands out as one of the most resolutely optimistic urban scholars. In his August 2022 Bloomberg column, “Why Downtown Won’t Die,”

His answer:

Great downtowns are not reducible to offices. Even if the office were to go the way of the horse-drawn carriage, the neighborhoods we refer to today as downtowns would endure. Downtowns and the cities they anchor are the most adaptive and resilient of human creations; they have survived far worse. Continual works in progress, they have been rebuilt and remade in the aftermaths of all manner of crises and catastrophes — epidemics and plagues; great fires, floods and natural disasters; wars and terrorist attacks. They’ve also adapted to great economic transformations like deindustrialization a half century ago.

Florida wrote that many urban central business districts are “relics of the past, the last gasp of the industrial age organization of knowledge work the veritable packing and stacking of knowledge workers in giant office towers, made obsolete and unnecessary by new technologies.”

“Downtowns are evolving away from centers for work to actual neighborhoods. Jane Jacobs titled her seminal 1957 essay, which led in fact to ‘The Death and Life of Great American Cities,’ ‘Downtown Is for People’ — sounds about right to me.”

Despite his optimism, Florida acknowledged in his email thatAmerican cities are uniquely vulnerable to social disorder — a consequence of our policies toward guns and lack of a social safety net. Compounding this is our longstanding educational dilemma, where urban schools generally lack the quality of suburban schools. American cities are simply much less family-friendly than cities in most other parts of the advanced world. So when people have kids they are more or less forced to move out of America’s cities.

What worries me in all of this, in addition to the impact on cities, is the impact on the American economy — on innovation. and competitiveness. Our great cities are home to the great clusters of talent and innovation that power our economy. Remote work has many advantages and even leads to improvements in some kinds of knowledge work productivity. But America’s huge lead in innovation, finances, entertainment and culture industries comes largely from its great cities. Innovation and advance in. these industries come from the clustering of talent, ideas and knowledge. If that gives out, I worry about our longer-run economic future and living standards.

The risk that comes with fiscal distress is clear: If city governments face budget shortfalls and begin to cut back on funding for public transit, policing, and street outreach, for the maintenance of parks, playgrounds, community centers, and schools, and for services for homelessness, addiction, and mental illness, then conditions in central cities will begin to deteriorate.

There is reason for both apprehension and hope. Cities across time have proven remarkably resilient and have survived infectious diseases from bubonic plague to cholera to smallpox to polio. The world population, which stands today at eight billion people, is 57 percent urban, and because of the productivity, innovation and inventiveness that stems from the creativity of human beings in groups, the urbanization process is quite likely to continue into the foreseeable future. There appears to be no alternative, so we will have to make it work.

the most explosive growth has been in Indigenous, independent Pentecostal churches

we ought to start talking about a new family of “spiritual” churches that have no historical ties to Western church traditions. These “spiritual” churches are largely not a result of colonial missions.

Sub-Saharan Africa had the most striking growth of Christianity, growing from around 9 percent Christian at the beginning of the 20th century to almost 45 percent at the end of it. There are around 685 million Christians in Africa now.

even conservative estimates guess there were around 98 million evangelical Christians globally in 1970. Now, there are over 342 million.

as Christianity booms overseas, more Christians are migrating to the United States. But there’s also evidence that migrants who come to here are finding immigrant-led churches and converting to Christianity after they arrive. These trends, George told me, are “globalizing American Christianity.”

Today, the three largest Protestant churches in Paris are Afro-Caribbean evangelical megachurches of a charismatic or Pentecostal bent

Immigration has been a huge factor in the demographic growth of the United States over the past decade. Much of that growth is attributable to Latinos, who now number around 62 million and represent just under 20 percent of the United States population. Some projections estimate that by 2060 there will be 111 million Latinos in the United States, constituting 28 percent of the population.

Latino evangelicals are the fastest growing segment of evangelicals in the country. It also said that “Latino Protestants, in particular, have higher levels of religiosity”

as of 2021, Pew reported that 29 percent of all adults identified as atheists, agnostics or “nothing in particular.”

alongside that trend, the changing demographics of Christianity promise to transform faith and religious discourse. We cannot assume that America will become more secular so long as the future of America is less white

it is difficult to provide definite statistics on how many evangelical and Pentecostal churches in America are led by Latinos, immigrants or other nonwhite or non-English-speaking pastors because many of these churches are small, non-organized and grass roots.

the standard American religious survey categories no longer account for the realities expressed in the church in America. “White evangelicalism,” “Protestant mainline” and “progressive” are categories that are largely defined by a white majority.

This “browning” of the church in America, as some scholars call it, scrambles all the categories. What we are seeing isn’t simply that white evangelicalism is changing; it’s that something new is emerging.

most hold convictions that overlap with traditional evangelicalism in substantial ways. They are by and large traditionally conservative about sexuality and marriage. They hold an authoritative view of the Bible and believe in miracles and supernatural occurrences.

But they tend to be more committed to social justice and, in George’s words, “communitarian” than many white evangelicals.

when he visits churches in Brazil and Argentina, “Sometimes the Catholics are more evangelical and Pentecostal” than even typical white evangelicals in America.

This influx of nonwhite believers will challenge white religious conservatives to choose between xenophobia and building alliances with immigrants who share their views on social issues.

These trends will also challenge them to unbundle their religious views on social issues from a kind of libertarian economics that harms those who are less wealthy

The future of American Christianity now appears to be a multiethnic community that is largely led by immigrants or the children of immigrants. And that reality ought to change our present conversations about religion in America.
