“Many people around Putin and many people in this country, they hate the [1993] constitution because it’s too liberal for them,” Ryzhkov said. “Now that Putin opened this Pandora’s box of changing the constitution, all these conservative, reactionary, nationalistic, xenophobic, anti-European, anti-liberal political forces feel the possibility to kill this constitution, to kill this liberal spirit.”“That’s the reason,” he added, “so many crazy amendments are being proposed now.”

After 2024, Putin could take on a powerful post-presidency role such as State Council head. Vesting new powers in that body could create a vehicle for him to steer foreign and military policy and to ensure that his vision of Russia as a great world nuclear power does not unravel in some future orgy of corruption and incompetence.

“Putin becomes the successor of himself,” Kolesnikov said. “But institutionally this is a problem because the simultaneous existence of the president, who is still empowered, and the head of a State Council, could generate conflict between these two figures.“This has only been developed for Putin. There is no practical need for any kind of chair of the State Council,” he said. “This is all about Putin himself, not about the political structure.

if the WHO had harshly attacked the Chinese response, we would have gotten even less cooperation and information out of China.

The WHO began working with the Centers for Disease Control and Prevention on Jan. 1 — a day after China disclosed the virus — and sent out advisories to worldwide public-health leaders beginning Jan. 5. Its scientists first got into Wuhan on Jan. 20, and on Jan. 23 it warned of a 4 percent death rate, human-to-human transmission and potential exporting of the virus to “any country.”

The WHO’s director-general, Tedros Adhanom Ghebreyesus, visited Beijing and secured permission for a dozen scientists, including from the CDC, to tour the affected areas from Feb. 16 to Feb. 24.

The scientists issued a report warning that the virus is “spreading with astonishing speed” and called for governments to “immediately activate the highest level of national response,” including immediate and extensive testing and planning for closing schools and workplaces.

And yet, Trump slept. “One day, it’s like a miracle, it will disappear,” he said on Feb. 28.

the Russian disinformation effort has proven far harder to track and combat because Russian operatives were taking advantage of Facebook’s core functions, connecting users with shared content and with targeted native ads to shape the political environment in an unusually contentious political season, say people familiar with Facebook’s response.

Unlike the Islamic State, what Russian operatives posted on Facebook was, for the most part, indistinguishable from legitimate political speech. The difference was the accounts that were set up to spread the misinformation and hate were illegitimate.

Facebook’s cyber experts found evidence that members of APT28 were setting up a series of shadowy accounts — including a persona known as Guccifer 2.0 and a Facebook page called DCLeaks — to promote stolen emails and other documents during the presidential race. Facebook officials once again contacted the FBI to share what they had seen.

The sophistication of the Russian tactics caught Facebook off-guard. Its highly regarded security team had erected formidable defenses against traditional cyber attacks but failed to anticipate that Facebook users — deploying easily available automated tools such as ad micro-targeting — pumped skillfully crafted propaganda through the social network without setting off any alarm bells.

One of the theories to emerge from their post-mortem was that Russian operatives who were directed by the Kremlin to support Trump may have taken advantage of Facebook and other social media platforms to direct their messages to American voters in key demographic areas in order to increase enthusiasm for Trump and suppress support for Clinton.

the intelligence agencies had little data on Russia’s use of Facebook and other U.S.-based social media platforms, in part because of rules designed to protect the privacy of communications between Americans.

“It is our responsibility,” he wrote, “to amplify the good effects [of the Facebook platform] and mitigate the bad — to continue increasing diversity while strengthening our common understanding so our community can create the greatest positive impact on the world.”

The extent of Facebook’s internal self-examination became clear in April, when Facebook Chief Security Officer Alex Stamos co-authored a 13-page white paper detailing the results of a sprawling research effort that included input from experts from across the company, who in some cases also worked to build new software aimed specifically at detecting foreign propaganda.

“Facebook sits at a critical juncture,” Stamos wrote in the paper, adding that the effort focused on “actions taken by organized actors (governments or non-state actors) to distort domestic or foreign political sentiment, most frequently to achieve a strategic and/or geopolitical outcome.” He described how the company had used a technique known as machine learning to build specialized data-mining software that can detect patterns of behavior — for example, the repeated posting of the same content — that malevolent actors might use.  

The software tool was given a secret designation, and Facebook is now deploying it and others in the run-up to elections around the world. It was used in the French election in May, where it helped disable 30,000 fake accounts, the company said. It was put to the test again on Sunday when Germans went to the polls. Facebook declined to share the software tool’s code name. 

Officials said Stamos underlined to Warner the magnitude of the challenge Facebook faced policing political content that looked legitimate. Stamos told Warner that Facebook had found no accounts that used advertising but agreed with the senator that some probably existed. The difficulty for Facebook was finding them.

Technicians then searched for “indicators” that would link those ads to Russia. To narrow down the search further, Facebook zeroed in on a Russian entity known as the Internet Research Agency, which had been publicly identified as a troll farm.

By early August, Facebook had identified more than 3,000 ads addressing social and political issues that ran in the United States between 2015 and 2017 and that appear to have come from accounts associated with the Internet Research Agency.

Congressional investigators say the disclosure only scratches the surface. One called Facebook’s discoveries thus far “the tip of the iceberg.” Nobody really knows how many accounts are out there and how to prevent more of them from being created to shape the next election — and turn American society against itself.

To Eisenhower it seemed that the press, at once credulous and cynical, was building up McCarthy. In a speech to newspaper publishers, he accused journalists of cheap sensationalism, of presenting “clichés and slogans” instead of facts

How could a responsible press not report what McCarthy said? The same quandary attends the media today, as they figure out how to handle “fake news” and the president’s intemperate tweets. Now, as then, no good solution exists.

Those who covered McCarthy’s every move inevitably became his “co-conspirators,” as one of them, Murray Kempton, later said. “In the end, I did not feel any cleaner than he was

Then as now, the press could achieve only so much, and for a reason that hasn’t changed. McCarthy was a political problem, not a journalistic one—a problem that could be solved in the end only by politics, by Eisenhower himself, who fooled almost everyone in deftly outmaneuvering McCarthy.

The journalist Theodore H. White, traveling through Texas in 1954 to interview conservatives in “the land of wealth and fear,” including the new cast of oil billionaires, discovered articles of faith not recognized much in newsrooms or by broadcasters like Edward R. Murrow. One was that “Joe McCarthy is the senior patriot of the nation.” Another was that “both older American parties are legitimate objects of deep suspicion.” These conservatives were nominally Republican but were enrolled in “a nameless Third Party, obsessed with hate, fear, and suspicion—one of whose central tenets is that ‘if America is ever destroyed it will be from within.’ ”

They figured out that “Joe never plans a damn thing … [and] doesn’t know from one week to the next, not even from one day to the next, what he’s going to be doing,” as William Rogers, the deputy attorney general, said. “He just hits out in any direction.” Leading him into self-destructive blundering was easy enough to do, but it couldn’t be rushed.

Eisenhower himself equated politics with war, both zero-sum games in which “it’s win or lose,” with nothing in between, and no points won for rectitude or grand displays of valor.

Privately, he had assessed McCarthy’s “demagogic skills,” Nichols notes, and shrewdly decided against “saying or doing anything that would make himself, not McCarthy, the issue.”

Stevenson had been right when he said the GOP was splitting in two. Eisenhower represented its doomed moderate East Coast faction—the party of Thomas E. Dewey, the New York governor who lost to Roosevelt in 1944 and Truman in 1948. Its voice was the editorial page of The New York Herald Tribune, with cheerleading from Henry Luce’s magazines.

McCarthy spoke to a newer constituency, based in the Midwest and, increasingly, the Sun Belt.

Eisenhower defeated McCarthy through stealth.

Eisenhower versus McCarthy looked in its moment to be “one of the great constitutional crises of our history,” in Lippmann’s words. Perhaps. But more practically, it was a war within the Republican Party, and the battle was as much cultural as ideological.

McCarthy wasn’t appreciably more or less anti-Communist than many others, Republicans or Democrats. He had no program to speak of and little interest in economics or in exploiting racial and religious fears. His enemy was what would soon be called the establishment—the policy elite in Beltway institutions. He attacked the CIA, the State Department, and overseas enterprises like the Voice of America.

What finished McCarthy was his rash decision to resume his attack on the executive branch with a popular Republican in office. Had Eisenhower not been so well liked, a national hero, McCarthy might have won. Demagogues sometimes do.

His genius was for disruption. He was one of those “men of factious tempers, of local prejudices, or of sinister designs,” who, as James Madison warned in the Federalist Papers, “may, by intrigue, by corruption, or by other means, first obtain the suffrages, and then betray the interests, of the people.”

Eisenhower seemed a savior from central casting.

. “Pod Save America,” by contrast, isn’t afraid to, as Ben Wikler of MoveOn puts it, “actually touch Excalibur.” At the theater in Richmond this month, shortly before bringing Northam and the rest of Virginia’s Democratic ticket onstage, Favreau asked the crowd: “Is everyone registered to vote? Is everyone going to be doing phone-banking and canvassing? Because if not, you have to leave.”

Soon, their discussion turned to the Trump administration. “It’s so unbelievable that these guys are trying to run anything,” Kristol lamented. “This level of total insanity is terrible.” 33 Comments “You know what?” Lovett told Kristol. “I like you better lately. It’s like we’re together to fight the aliens.” Advertisement Continue reading the main story “It’s like we’re all defending the Earth!” Kristol said.“But at some point the aliens will leave,” Lovett reminded him. “And then we’ll just be sitting at the same table being like, ‘Oh, right, we hate each other.’ ”

Then Vietor and Lovett spotted Bill Kristol, the founding editor of The Weekly Standard and a neoconservative boogeyman to liberals during the George W. Bush presidency, who emerged as one of the most forthright conservative critics of Trump in 2016. They introduced themselves and fell into conversation about the 2008 election. “You guys had a good team,” Kristol said. “It seems like another era: Hillary and Obama debating the intricacies of whether you could do health care reform without a mandate or with a mandate.”

he sees some parallels between the conservative cable channel and Crooked Media. “This was true of Roger: It’s not just a business for these Crooked Media guys, it’s a calling,” he told me. “The real execution challenge is about authenticity. Does it feel authentic to the audience? They certainly have that going for them.”

assuming standard industry rates, Crooked Media is most likely bringing in at least $50,000 in advertising revenue for each episode of “Pod Save America” — which at two episodes a week is about $5 million a year.

Some officials from Erdogan’s Islam-oriented party had advocated for a review of the agreement, arguing it is inconsistent with Turkey’s conservative values by encouraging divorce and undermining the traditional family unit.

They see that as a threat to Turkish families. Hate speech has been on the rise in Turkey, including the interior minister who described LGBT people as “perverts” in a tweet. Erdogan has rejected their existence altogether.

Rights groups say violence against and killing of women is on the rise in Turkey but the interior minister called that a “complete lie” on Saturday.

“It is clear that this decision will further encourage the murderers of women, harassers, rapists,” their statement said.

Erdogan has repeatedly stressed the “holiness” of the family and called on women to have three children. His communications director, Fahrettin Altun, said the government’s motto was ’Powerful Families, Powerful Society.”

Hundreds of women and allies gathered in Istanbul, wearing masks and holding banners. Their demonstration has so far been allowed but the area was surrounded by police and a coronavirus curfew is begins in the evening. They shouted pro-LGBT slogans and called for Erdogan’s resignation. They cheered as a woman speaking through a megaphone said, “You cannot close up millions of women in their homes. You cannot erase them from the streets and the squares.”

Turkey was the first country to sign the Council of Europe’s “Convention on preventing and combating violence against women and domestic violence” at a committee of ministers meeting in Istanbul in 2011. The law came into force in 2014 and Turkey’s constitution says international agreements have the force of law.

But Erdogan gained sweeping powers with his re-election in 2018, setting in motion Turkey changing from a parliamentary system of government to an executive presidency.

On Monday, the platform went dark after a hacker took over the accounts of 178 users, including Torba and the Republican congresswoman Marjorie Taylor Greene.

Gab, a Twitter-like website promoted by Torba as a bastion of free speech, has long been a forum of last resort for extremists and conspiracy theorists who have been banned on other online platforms. It attained worldwide notoriety in 2018 when a user, Robert Bowers, wrote on the site that he was “going in”, shortly before allegedly entering the Tree of Life synagogue in Pittsburgh, Pennsylvania, and killing eleven people.

The leaked files contained what appears to be a database of over 4.1 million registered users on the site and tags identifying subscribers as “investors”, “verified” users and “pro” users.

The 2017 share offering, for example, required a minimum investment of $199.10, and rewarded investors who contributed a greater amount with “perks”. Users who invested $200 could display a “Gab investor badge” on the site. The badges corresponded with a tag in the database, which allowed investors to be looked at in detail.

Some of the people associated with investors’ accounts had high-profile jobs and public roles, while spewing hate and extremist beliefs online.

The data breach also appears to offer some insight into users tagged as “verified” by Gab, which according to the platform’s own explanation means that they have completed a verification process that includes matching their display name to a government ID.

And it appears to include a list of users registered as “pros”, which allows users to access additional features and a badge at a price starting at $99 year. The database indicates over 18,000 users had paid to be pro users at the time of the breach. Nearly 4,000 users were flagged as donors to Gab’s repeated attempts to attract voluntary gifts from users.

Direct messages included in the leak appear to show close communication between Torba and a major QAnon influencer who is labeled a Gab investor, seemingly reinforcing the CEO’s public efforts to make Gab a home for adherents to the QAnon conspiracy theory, which helped fuel the 6 January attack on the nation’s Capitol.

According to Wired, the data exposed in the apparent hack was sourced by a hacker who had found a security vulnerability in the site.

“Gab was negligent at best and malicious at worst” in its approach to security, she added. “It is hard to envision a scenario where a company cared less about user data than this one.”

For a century, the Tulsa race massacre of May 31, 1921, went largely ignored by sitting U.S. presidents, never prompting a trip specifically to honor those killed in the once-thriving Black neighborhood of Greenwood until now.

The Black educator Booker T. Washington coined the name "Black Wall Street" for Greenwood in recognition of thriving Black middle, upper and professional classes with Black-owned businesses dotting the streets.

At roughly 100 days into Biden's presidency, 89% of Black Americans say they approved of the job he is doing – more than any other racial group, according to a Pew Research Center poll. The administration's responses, particularly regarding economic inequality and criminal justice will be closely watched. The George Floyd Justice in Policing Act, which many had touted would pass by the anniversary of Floyd's death May 25, remains with the Senate.

The White House has been criticized by some racial justice advocates for not going far enough in advancing some police reform and other progressive measures, though activists have conceded Biden officials are more responsive than past administrations on the issue.

On Thursday, Mr. Biden ordered that flags outside the White House, other public buildings, military posts and naval stations in the District of Columbia and throughout the country and its territories be flown at half-staff to honor the victims of the Atlanta spa shootings.

Mr. Biden said on Wednesday that “the question of motivation is still to be determined” in the Georgia shootings, while renewing his concerns over a recent surge in violence against Asian-Americans.

In his first prime-time speech as president last week, marking a year of the coronavirus pandemic, Mr. Biden denounced “vicious hate crimes against Asian-Americans, who have been attacked, harassed, blamed and scapegoated.”

Ms. Harris, the first woman and the first Asian-American to hold the office, expressed condolences for the families of the victims on Wednesday

“This speaks to a larger issue, which is the issue of violence in our country and what we must do to never tolerate it and to always speak out against it,” Ms. Harris said

Several states in the Northeast also have among the country’s worst outbreaks now. Connecticut, New Jersey and Pennsylvania, among others, are all experiencing marked rises in case counts, and labs have identified both the B.1.1.7 variant and large shares of another variant, B.1.526.

The B.1.526 variant, which first appeared in New York City in samples from November, appears in two forms: one with a mutation that may help the virus evade antibodies and another that may help it bind more tightly to human cells.

The outbreak in the Northeast is currently much worse than it is in California, but California faces a variant of its own that makes up a large share of cases.

Studies have indicated the variant first discovered in California, B.1.427/B.1.429, may also be more transmissible than earlier forms of the virus, but it does not appear to spread as quickly as B.1.1.7.

Like the variant first discovered in New York City, the B.1.427/B.1.429 variant has also been seen in high levels in neighboring states, including Arizona, but does not yet make up a significant number of cases outside the region.

In Michigan, Covid-19 hospitalizations are already more than three times higher than they were a month ago. Other states with rising cases are also seeing significant increases in hospitalized Covid-19 patients.

The vaccine rollout continues to speed up, and recent studies confirm that vaccines are effective against the coronavirus in the real world, giving experts hope that an end may be in sight. But with increased transmission, they say, comes a renewed need for caution in the immediate term.

“I think we’ve got to hang on just a little bit longer, being conservative and getting more people vaccinated,” Dr. Martin said. “I’d hate to see us having another hospital surge when we’re getting so close to being done with this. I’m definitely worried about it.”

Since violence between Israelis and Palestinians escalated last week, at least 100 new WhatsApp groups have been formed for the express purpose of committing violence against Palestinians, according to an analysis by The New York Times and FakeReporter, an Israeli watchdog group that studies misinformation.

While social media and messaging apps have been used in the past to spread hate speech and inspire violence, these WhatsApp groups go further, researchers said. That’s because the groups are explicitly planning and executing violent acts against Palestinian citizens of Israel, who make up roughly 20 percent of the population and live largely integrated lives with Jewish neighbors.

That is far more specific than past WhatsApp-fueled mob attacks in India, where calls for violence were vague and generally not targeted at individuals or businesses

Even the Stop the Steal groups in the United States that organized the Jan. 6 protests in Washington did not openly direct attacks using social media or messaging apps,

In the groups, attacks have been carefully documented, with members often gloating about taking part in the violence, according to The Times’s review. Some said they were taking revenge for rockets being fired onto Israel from militants in the Gaza Strip, while others cited different grievances. Many solicited names of Arab-owned businesses they could target next.

“It is a perfect storm of people empowered to use their own names and phone numbers to openly call for violence, and having a tool like WhatsApp to organize themselves into mobs,” said Achiya Schatz, director of FakeReporter.

Micky Rosenfeld, a spokesman for the Israeli police, said, “Police are tracking social media and monitoring movements on the ground.” He said that while Israelis have been involved in some attacks, they were largely “protecting themselves” against attacks by Palestinian citizens of Israel. He added, “Police investigations are continuing.”

One official, who spoke on the condition of anonymity, added that the police had not seen similar WhatsApp groups forming among Palestinians.

Islamist movements, including Hamas, the militant Palestinian organization that controls the Gaza Strip, have long organized and recruited followers on social media but do not plan attacks on the services for fear of being discovered.

A WhatsApp spokeswoman said the messaging service was concerned by the activity from Israeli extremists. She said the company had removed some accounts of people who participated in the groups. WhatsApp cannot read the encrypted messages on its service, she added, but it has acted when accounts were reported to it for violating its terms of service.

The groups have since grown steadily in size, Mr. Schatz said. Some have become so big that they have branched off into local chapters that are dedicated to certain cities and towns. To evade detection by WhatsApp, organizers of the groups are urging people to vet new members, he said.

On one new Telegram channel that The Times reviewed, “The Revenge Troops,” people recently shared instructions for how to build Molotov cocktails and makeshift explosives. The group asked its 400 members to also provide addresses of Arab-owned businesses that could be targeted.

In another group with just under 100 members, people shared photos of guns, knives and other weapons as they discussed engaging in street combat in mixed Jewish-Arab cities. Another new WhatsApp group was named “The unapologetic right-wing group.”

“We destroyed them, we left them in pieces,” said one person in “The Revenge Troops” Telegram channel, alongside a photo showing smashed car windows. In a different group, a video was uploaded of black-clad Jewish youths stopping cars on an unnamed street and asking drivers if they were Jewish or Arab.

We beat “the enemy car-by-car,” said a comment posted underneath the video, using an expletive.

“Our government is too weak to do what is necessary, so we take it into our own hands,” wrote one person in a WhatsApp group dedicated to the city of Ramle in central Israel. “Now that we have organized, they can’t stop us.”

"It was a powerful moment because he did his own eulogy."

The following day, Ester and a number of King supporters, gathered at the Lorraine Motel, where the civil rights leader was staying.

"All of a sudden what sounded like a truck backfiring goes off and I can hear people saying, 'Get down, get down!' "

"I'm looking, still, at Dr. King being thrown back and I take off and I run up the steps. And when I get up to where he's laying, I notice this pool of blood around his head,"

In that moment, kneeling over his body, Ester said King's fateful words from the night before were echoing in her head: I may not get there with you. I may not get there with you.

hate "took over." It stemmed, she said, from "white America [who] don't want to see us with freedom, so you take out our leader, our king."

"Every time I want to believe that Dr. King's life changed everything — I've witnessed George Floyds and so many others that have lost their lives," Ester said, referring to the man fatally killed by Minneapolis police last May.

Still, in contemplating what King's legacy has meant after decades of violence against Black people, Clara said, "You think that's gonna destroy his dream? Y'all are wrong. I think children years and years to come will continue to have his dream."

In the three years since Google Brain began making smart recommendations, watch time from the YouTube home page has grown 20-fold. More than 70 percent of the time people spend watching videos on YouTube, they spend watching videos suggested by Google Brain.

The more videos that are watched, the more ads that are seen, and the more money Google makes.

“We also wanted to serve the needs of people when they didn’t necessarily know what they wanted to look for.”

Last week, The New York Times reported that YouTube’s algorithm was encouraging pedophiles to watch videos of partially-clothed children, often after they watched sexual content.

o YouTube’s nuance-blind algorithm — trained to think with simple logic — serving up more videos to sate a sadist’s appetite is a job well done.

The result? The algorithm — and, consequently, YouTube — incentivizes bad behavior in viewers.

the algorithm relies on snapshots of visual content, rather than actions. If you (or your child) watch one Peppa Pig video, you’ll likely want another. And as long as it’s Peppa Pig in the frame, it doesn’t matter what the character does in the skit.

it didn’t take long for inappropriate videos to show up in YouTube Kids’ ‘Now playing’ feeds

Using cheap, widely available technology, animators created original video content featuring some of Hollywood’s best-loved characters. While an official Disney Mickey Mouse would never swear or act violently, in these videos Mickey and other children’s characters were sexual or violent

there’s a 3.5 percent chance of a child coming across inappropriate footage within 10 clicks of a child-friendly video.

Just four in 10 parents always monitor their child’s YouTube usage — and one in 20 children aged 4-to-12 say their parents never check what they’re watching.

At the height of the panic around Mr. Crowder’s videos, YouTube’s public policy on hate speech and harassment appeared to shift four times in a 24-hour period as the company sought to clarify what the new normal was.

One possible solution that would address both problems would be to strip out YouTube’s recommendation altogether. But it is highly unlikely that YouTube would ever do such a thing: that algorithm drives vast swaths of YouTube’s views, and to take it away would reduce the time viewers spend watching its videos, as well as reduce Google’s ad revenue.

it must, at the very least, make significant changes, and have greater human involvement in the recommendation process. The platform has some human moderators looking at so-called “borderline” content to train its algorithms, but more humanity is needed in the entire process.

Currently, the recommendation engine cannot understand why it shouldn’t recommend videos of children to pedophiles, and it cannot understand why it shouldn’t suggest sexually explicit videos to children. It cannot understand, because the incentives are twisted: every new video view, regardless of who the viewer is and what the viewer’s motives may be, is considered a success.

Republicans have long ignored Trump’s habit of openly using violent rhetoric that puts people at risk. GOP lawmakers, when asked whether they support what Trump says, have consistently tried to pretend they never see his tweets. Or they insist the tweets don’t matter. Or they simply refuse to weigh in on what he’s said.

“If you see somebody getting ready to throw a tomato, knock the crap out of them, would you? Seriously. Just knock the hell out of them.” At another campaign rally that year, he said of a protester: “I’d like to punch him in the face.”

“The audience swung back. And I thought it was very, very appropriate,” he said in an interview. “He was swinging, he was hitting people and the audience hit back. And that’s what we need a little bit more of.”

Trump has constantly demonized the media and encouraged his supporters to treat journalists as “the enemy of the people.” He berates and belittles reporters when they ask him questions he doesn’t like, becoming particularly incensed when female journalists challenge him.

Mr. Trump was holding rallies in five states on Sunday after spending a full day in Pennsylvania on Saturday.

Mr. Biden has also faulted Mr. Trump for endangering his own supporters.“I’m being responsible and I’m not becoming a great spreader of Covid,” Mr. Biden said last week, making explicit the distinction that he has been trying to draw for months. Mr. Trump, he said, is “putting thousands of people at risk.”

Mr. Trump bragged about attracting bigger crowds than Mr. Biden and former President Barack Obama, who campaigned together on Saturday. “I hate to say it, Obama doesn’t draw any better,” he said. “They went as a twosome and they had less people.”

But Mr. Trump is less enthusiastic when the input comes from smaller crowds. On Saturday morning, as he spoke to only about 300 people at his first Pennsylvania rally of the day, Mr. Trump was lethargic and subdued, as if he were privately thinking to himself: Yawn.

“A great red wave is forming,” Mr. Trump said on Saturday in Newtown, Pa. “As sure as we’re here together, that wave is forming. And they see it, they see it on all sides, and there’s not a thing they can do about it.”

“It’s a great way to show the enthusiasm and get the feeling of a campaign while being Covid safe,” said Jenn Ridder, the national states director for the Biden campaign. “People love them. They love the honking and the noise. I think people want to feel part of something, and especially in Covid.”

“The horns can be really cool as far as call and response,” said Lt. Gov. Garlin Gilchrist II of Michigan, who spoke at the rallies in Flint and Detroit. “You have people kind of sitting on top of their cars, or hanging out the window.”

“It kind of personifies this campaign,” Mr. Gilchrist added. “Joe Biden is a person who values human connection.”

But the format allows for something that has been missing when Mr. Biden gives speeches during the pandemic in front of small groups of reporters: audible feedback from the crowd, even if it is different from the applause at Mr. Trump’s rallies.

While President Trump still thrills to the roar of a crowd, even during a pandemic, Joe Biden has found a new way to get audience feedback: through honking horns at his drive-in rallies.

Both men put those competing identities on display as they dashed across battleground states over the weekend.

Mr. Trump enters his rallies to pounding music and crowds roaring their approval — with few people wearing masks — as he throws Make America Great Again hats into the stands like T-shirts at a basketball game.

On Sunday, Mr. Trump also had rallies scheduled in Dubuque, Iowa; Hickory, N.C.; Rome, Ga.; and Opa-locka, Fla. — the last one at 11 p.m.

t the event in Flint, Mr. Obama mocked his successor for his “obsession” with crowd size, asking: “Did no one come to his birthday party when he was a kid? Was he traumatized?”

For attendees, it is a new experience, and they have different approaches to taking in the proceedings. Some people stay inside their cars, allowing easy access to honking. Others stand near their cars, a position that allows for sign hoisting or flag waving.

the obstacles to prosecuting such cases more aggressively point to another problem making the German authorities increasingly anxious: Infiltration of the very institutions, like the police, that are supposed to be doing the investigating.

In July the police chief of the western state of Hesse resigned after police computers had been repeatedly accessed for confidential information that was then used by neo-Nazis in death threats. It was in Hesse that a well-known neo-Nazi assassinated a regional politician last summer in a case that woke many Germans to the threat of far-right terrorism.

The region where they live is nestled between the former Iron Curtain and the Polish border. Members had grown up in the former East Germany.

There were two criteria for joining, Mr. Moll recalled: “The right skills and the right attitude.”Mr. Gross and another police officer in the group were members of what was then an emerging far-right party, the Alternative for Germany, now the third largest force in the national Parliament. At least two others in the group had visited the Thule Seminar, an organization whose leaders had a portrait of Hitler on their wall and preach white supremacy.

Over time, Nordkreuz members recalled, their group morphed into a close-knit brotherhood with a shared ambition that would come to dominate their lives: preparing for Day X.

The group identified a “safe house,” where members would decamp with their families on Day X: a former Communist vacation village deep in the woods.

“This movement has its fingertips in lots of places,” he said. “All this talk of Day X can seem like pure fantasy. But if you look closer, you can see how quickly it turns into serious planning — and plotting.”

“Under Communism, everything was scarce,’’ Mr. Moll explained. ‘‘You had to get creative getting things through certain channels. You could not rely on things being in the supermarket. You could say we’re used to prepping.’’

“The scenario was that something bad would happen,” Mr. Gross told me. “We asked ourselves, what did we want to prepare for? And we decided that if we were going to do this, we would go all the way.”

But at least one member of the group portrays a more ominous story.“People were to be gathered and murdered,” Horst Schelski told investigators in 2017, according to transcripts of his statement shared with The New York Times.

Jan Henrik H. was described by other members as particularly fervent and hateful. On his birthdays, he held a shooting contest on a field behind his house in Rostock, a nearby city on Germany’s northern coast, Nordkreuz members recalled.The winner got a trophy named for Mehmet Turgut, a Turkish street vendor killed in Rostock in 2004 by the National Socialist Underground, a far-right terrorist group.

As they drank coffee at the truck stop, Jan Henrik H. turned the conversation to “the people in the file,” who he said were “harmful” to the state and needed to be “done away with,” Mr. Schelski later told the police.Jan Henrik H. wanted advice on how best to transport their captives once they had been rounded up. He asked Mr. Schelski, a major in the state reservist unit, how they could get them past any checkpoints that might be created in a time of unrest. Would uniforms help? Army trucks?

“They showed me a handmade sketch of my home,” Mr. Böhringer said. “‘Do you recognize this?’ they had asked.”“It was the exact same sketch that those officers had made in my home,” he said.“I had to swallow pretty hard,” he recalled. “The very people who said they wanted to protect me then passed this on to people who wanted to harm me.”“They didn’t just want to survive Day X, they wanted to kill their enemies,” he said. “It was concrete, what they were planning.”

Chancellor Angela Merkel belongs “in the dock,” he said. The multicultural cities in western Germany are “the caliphate.” The best way to escape creeping migration was to move to the East German countryside, “where people are still called Schmidt, Schneider and Müller.”A copy of Compact, a prominent far-right magazine, with President Trump’s face on the cover, lay on a shelf. A selection of the president’s speeches had been translated into German in the issue. “I like Trump,” Mr. Gross said.

As far back as 2009, some fellow police officers had voiced concerns about Mr. Gross’s far-right views, noting that he had brought books about the Nazis to work. But no one intervened, and he was even groomed for promotion.“There is no danger from the far right,” he insisted. “I don’t know a single neo-Nazi.”Soldiers and police officers are “frustrated,” he told me the third time we met, ticking off complaints about migrants, crime and the mainstream media. He likens the coverage of coronavirus to the censored state broadcaster during Communism. Instead, he says, he has a YouTube subscription to RT, the Russian state-controlled channel and other alternative media.In that parallel universe of disinformation, he learns that the government is secretly flying in refugees after midnight. That coronavirus is a ploy to deprive citizens of their rights. That Ms. Merkel works for what he calls the “deep state.”“The deep state is global,” Mr. Gross said. “It’s big capital, the big banks, Bill Gates.”

He still expects Day X, sooner or later. Riots linked to an economic meltdown. Or a blackout, because the German government is shuttering coal plants.Nordkreuz members never told me, nor the authorities, the location of the disused vacation village that was their safe house for Day X.The safe house is still active, said Mr. Gross, who at the height of Nordkreuz’s planning had boasted to a fellow member that his network contained 2,000 like-minded people in Germany and beyond.“The network is still there,” he said.

I’d been talking with DiAngelo for a year when Floyd was killed, and with other antiracism teachers for almost as long. Demand has recently spiked throughout the field, though the clamor had already been building, particularly since the election of Donald Trump

As their teaching becomes more and more widespread, antiracism educators are shaping the language that gets spoken — and the lessons being learned — about race in America.

“I will not coddle your comfort,” she went on. She gestured crisply with her hands. “I’m going to name and admit to things white people rarely name and admit.” Scattered Black listeners called out encouragement. Then she specified the predominant demographic in the packed house: white progressives. “I know you. Oh, white progressives are my specialty. Because I am a white progressive.” She paced tightly on the stage. “And I have a racist worldview.”

“White supremacy — yes, it includes extremists or neo-Nazis, but it is also a highly descriptive sociological term for the society we live in, a society in which white people are elevated as the ideal for humanity, and everyone else is a deficient version.” And Black people, she said, are cast as the most deficient. “There is something profoundly anti-Black in this culture.”

But was I being fragile? Was I being defensive or just trying to share something more personal, intimate and complex than DiAngelo’s all-encompassing sociological perspective? She taught, throughout the afternoon, that the impulse to individualize is in itself a white trait, a way to play down the societal racism all white people have thoroughly absorbed.

At some point after our answers, DiAngelo poked fun at the myriad ways that white people “credential” themselves as not-racist. I winced. I hadn’t meant to imply that I was anywhere close to free of racism, yet was I “credentialing”?

the pattern she first termed “white fragility” in an academic article in 2011: the propensity of white people to fend off suggestions of racism, whether by absurd denials (“I don’t see color”) or by overly emotional displays of defensiveness or solidarity (DiAngelo’s book has a chapter titled “White Women’s Tears” and subtitled “But you are my sister, and I share your pain!”) or by varieties of the personal history I’d provided.

White fragility, in DiAngelo’s formulation, is far from weakness. It is “weaponized.” Its evasions are actually a liberal white arsenal, a means of protecting a frail moral ego, defending a righteous self-image and, ultimately, perpetuating racial hierarchies, because what goes unexamined will never be upended

One “unnamed logic of Whiteness,” she wrote with her frequent co-author, the education professor Ozlem Sensoy, in a 2017 paper published in The Harvard Educational Review, “is the presumed neutrality of White European Enlightenment epistemology.”

she returned to white supremacy and how she had been imbued with it since birth. “When my mother was pregnant with me, who delivered me in the hospital — who owned the hospital? And who came in that night and mopped the floor?” She paused so we could picture the complexions of those people. Systemic racism, she announced, is “embedded in our cultural definitions of what is normal, what is correct, what is professionalism, what is intelligence, what is beautiful, what is valuable.”

“I have come to see white privilege as an invisible package of unearned assets that I can count on cashing in each day, but about which I was ‘meant’ to remain oblivious,” one of the discipline’s influential thinkers, Peggy McIntosh, a researcher at the Wellesley Centers for Women, has written. “White privilege is like an invisible weightless knapsack of special provisions, assurances, tools, maps, guides, codebooks, passports, visas, clothes, compass, emergency gear and blank checks.”

Borrowing from feminist scholarship and critical race theory, whiteness studies challenges the very nature of knowledge, asking whether what we define as scientific research and scholarly rigor, and what we venerate as objectivity, can be ways of excluding alternate perspectives and preserving white dominance

the Seattle Gilbert & Sullivan Society’s casting of white actors as Asians in a production of “The Mikado.” “That changed my life,” she said. The phrase “white fragility” went viral, and requests to speak started to soar; she expanded the article into a book and during the year preceding Covid-19 gave eight to 10 presentations a month, sometimes pro bono but mostly at up to $15,000 per event.

For almost everyone, she assumes, there is a mingling of motives, a wish for easy affirmation (“they can say they heard Robin DiAngelo speak”) and a measure of moral hunger.

Moore drew all eyes back to him and pronounced, “The cause of racial disparities is racism. If I show you data that’s about race, we need to be talking about racism. Don’t get caught up in detours.” He wasn’t referring to racism’s legacy. He meant that current systemic racism is the explanation for devastating differences in learning, that the prevailing white culture will not permit Black kids to succeed in school.

The theme of what white culture does not allow, of white society’s not only supreme but also almost-absolute power, is common to today’s antiracism teaching and runs throughout Singleton’s and DiAngelo’s programs

unning slightly beneath or openly on the surface of DiAngelo’s and Singleton’s teaching is a set of related ideas about the essence and elements of white culture

if we were white and happened to be sitting beside someone of color, we were forbidden to ask the person of color to speak first. It might be good policy, mostly, for white people to do more listening than talking, but, she said with knowing humor, it could also be a subtle way to avoid blunders, maintain a mask of sensitivity and stay comfortable. She wanted the white audience members to feel as uncomfortable as possible.

For DiAngelo, the elements include the “ideology of individualism,” which insists that meritocracy is mostly real, that hard work and talent will be justly rewarded. White culture, for her, is all about habits of oppressive thought that are taken for granted and rarely perceived, let alone questioned

The modern university, it says, “with its ‘experts’ and its privileging of particular forms of knowledge over others (e.g., written over oral, history over memory, rationalism over wisdom)” has “validated and elevated positivistic, White Eurocentric knowledge over non-White, Indigenous and non-European knowledges.”

the idea of a society rigged at its intellectual core underpins her lessons.

There is the myth of meritocracy. And valuing “written communication over other forms,” he told me, is “a hallmark of whiteness,” which leads to the denigration of Black children in school. Another “hallmark” is “scientific, linear thinking. Cause and effect.” He said, “There’s this whole group of people who are named the scientists. That’s where you get into this whole idea that if it’s not codified in scientific thought that it can’t be valid.”

“This is a good way of dismissing people. And this,” he continued, shifting forward thousands of years, “is one of the challenges in the diversity-equity-inclusion space; folks keep asking for data. How do you quantify, in a way that is scientific — numbers and that kind of thing — what people feel when they’re feeling marginalized?”

Moore directed us to a page in our training booklets: a list of white values. Along with “ ‘The King’s English’ rules,” “objective, rational, linear thinking” and “quantitative emphasis,” there was “work before play,” “plan for future” and “adherence to rigid time schedules.”

They’ve just refined their analysis, with the help of two Princeton researchers, Chelsey Clark and Roni Porat. “As the study quality goes up,” Paluck told me, “the effect size dwindles.”

Dobbin’s research shows that the numbers of women or people of color in management do not increase with most anti-bias education. “There just isn’t much evidence that you can do anything to change either explicit or implicit bias in a half-day session,” Dobbin warns. “Stereotypes are too ingrained.”

he noted that new research that he’s revising for publication suggests that anti-bias training can backfire, with adverse effects especially on Black people, perhaps, he speculated, because training, whether consciously or subconsciously, “activates stereotypes.”

When we spoke again in June, he emphasized an additional finding from his data: the likelihood of backlash “if people feel that they’re being forced to go to diversity training to conform with social norms or laws.”

Donald Green, a professor of political science at Columbia, and Betsy Levy Paluck, a professor of psychology and public affairs at Princeton, have analyzed almost 1,000 studies of programs to lessen prejudice, from racism to homophobia, in situations from workplaces to laboratory settings. “We currently do not know whether a wide range of programs and policies tend to work on average,

She replied that if a criterion “consistently and measurably leads to certain people” being excluded, then we have to “challenge” the criterion. “It’s the outcome,” she emphasized; the result indicated the racism.

Another critique has been aimed at DiAngelo, as her book sales have skyrocketed. From both sides of the political divide, she has been accused of peddling racial reductionism by branding all white people as supremacist

Chislett filed suit in October against Carranza and the department. At least five other high-level, white D.O.E. executives have filed similar suits or won settlements from the city over the past 14 months. The trainings lie at the heart of their claims.

Chislett eventually wound up demoted from the leadership of A.P. for All, and her suit argues that the trainings created a workplace filled with antiwhite distrust and discrimination

whatever the merits of Chislett’s lawsuit and the counteraccusations against her, she is also concerned about something larger. “It’s absurd,” she said about much of the training she’s been through. “The city has tens of millions invested in A.P. for All, so my team can give kids access to A.P. classes and help them prepare for A.P. exams that will help them get college degrees, and we’re all supposed to think that writing and data are white values? How do all these people not see how inconsistent this is?”

I talked with DiAngelo, Singleton, Amante-Jackson and Kendi about the possible problem. If the aim is to dismantle white supremacy, to redistribute power and influence, I asked them in various forms, do the messages of today’s antiracism training risk undermining the goal by depicting an overwhelmingly rigged society in which white people control nearly all the outcomes, by inculcating the idea that the traditional skills needed to succeed in school and in the upper levels of the workplace are somehow inherently white, by spreading the notion that teachers shouldn’t expect traditional skills as much from their Black students, by unwittingly teaching white people that Black people require allowances, warrant extraordinary empathy and can’t really shape their own destinies?

With DiAngelo, my worries led us to discuss her Harvard Educational Review paper, which cited “rationalism” as a white criterion for hiring, a white qualification that should be reconsidered

Shouldn’t we be hiring faculty, I asked her, who fully possess, prize and can impart strong reasoning skills to students, because students will need these abilities as a requirement for high-paying, high-status jobs?

I pulled us away from the metaphorical, giving the example of corporate law as a lucrative profession in which being hired depends on acute reasoning.

Moore expounded that white culture is obsessed with “mechanical time” — clock time — and punishes students for lateness. This, he said, is but one example of how whiteness undercuts Black kids. “The problems come when we say this way of being is the way to be.” In school and on into the working world, he lectured, tremendous harm is done by the pervasive rule that Black children and adults must “bend to whiteness, in substance, style and format.”

he said abruptly, “Capitalism is so bound up with racism. I avoid critiquing capitalism — I don’t need to give people reasons to dismiss me. But capitalism is dependent on inequality, on an underclass. If the model is profit over everything else, you’re not going to look at your policies to see what is most racially equitable.”

I was asking about whether her thinking is conducive to helping Black people displace white people on high rungs and achieve something much closer to equality in our badly flawed worl

it seemed that she, even as she gave workshops on the brutal hierarchies of here and now, was entertaining an alternate and even revolutionary reality. She talked about top law firms hiring for “resiliency and compassion.”

Singleton spoke along similar lines. I asked whether guiding administrators and teachers to put less value, in the classroom, on capacities like written communication and linear thinking might result in leaving Black kids less ready for college and competition in the labor market. “If you hold that white people are always going to be in charge of everything,” he said, “then that makes sense.”

He invoked, instead, a journey toward “a new world, a world, first and foremost, where we have elevated the consciousness, where we pay attention to the human being.” The new world, he continued, would be a place where we aren’t “armed to distrust, to be isolated, to hate,” a place where we “actually love.”

I reread “How to Be an Antiracist.” “Capitalism is essentially racist; racism is essentially capitalist,” he writes. “They were birthed together from the same unnatural causes, and they shall one day die together from unnatural causes.”

“I think Americans need to decide whether this is a multicultural nation or not,” he said. “If Americans decide that it is, what that means is we’re going to have multiple cultural standards and multiple perspectives. It creates a scenario in which we would have to have multiple understandings of what achievement is and what qualifications are. That is part of the problem. We haven’t decided, as a country, even among progressives and liberals, whether we desire a multicultural nation or a unicultural nation.”

Ron Ferguson, a Black economist, faculty member at Harvard’s John F. Kennedy School of Government and director of Harvard’s Achievement Gap Initiative, is a political liberal who gets impatient with such thinking about conventional standards and qualifications

“The cost,” he told me in January, “is underemphasizing excellence and performance and the need to develop competitive prowess.” With a soft, rueful laugh, he said I wouldn’t find many economists sincerely taking part in the kind of workshops I was writing about

“When the same group of people keeps winning over and over again,” he added, summarizing the logic of the trainers, “it’s like the game must be rigged.” He didn’t reject a degree of rigging, but said, “I tend to go more quickly to the question of how can we get prepared better to just play the game.”

But, he suggested, “in this moment we’re at risk of giving short shrift to dealing with qualifications. You can try to be competitive by equipping yourself to run the race that’s already scheduled, or you can try to change the race. There may be some things about the race I’d like to change, but my priority is to get people prepared to run the race that’s already scheduled.”

DiAngelo hopes that her consciousness raising is at least having a ripple effect, contributing to a societal shift in norms. “You’re watching network TV, and they’re saying ‘systemic racism’ — that it’s in the lexicon is kind of incredible,” she said. So was the fact that “young people understand and use language like ‘white supremacy.’”

We need a culture where a person who resists speaking up against racism is uncomfortable, and right this moment it looks like we’re in that culture.”

Twice as many independent voters said they disapproved of Trump’s response to the unrest. Even among Republicans, only 67% said they approved of the way he had responded, significantly lower than the 82% who liked his overall job performance.

The officer has been charged with murder.

The survey conducted on Monday and Tuesday found 64% of American adults were “sympathetic to people who are out protesting right now,” while 27% said they were not and 9% were unsure.

Forty-seven percent of registered voters said they planned to support Biden in the Nov. 3 election, compared with 37% favoring Trump. Biden vowed not to “fan the flames of hate” in a speech on Tuesday about the unrest.

Public opinion could be particularly volatile as the protests continue to roil major cities every night. Several police officers were shot on Monday night, and Trump has derided governors who have not asked for military assistance.

The other poll conducted over the same period regarding Trump’s overall job performance and the 2020 election gathered responses from 1,113 American adults and had a credibility interval of plus or minus 3 percentage points.

in the end, Facebook’s interest was fleeting. Mr. Zuckerberg and other senior executives largely shelved the basic research, according to previously unreported internal documents and people familiar with the effort, and weakened or blocked efforts to apply its conclusions to Facebook products.

At Facebook, “There was this soul-searching period after 2016 that seemed to me this period of really sincere, ‘Oh man, what if we really did mess up the world?’

Another concern, they and others said, was that some proposed changes would have disproportionately affected conservative users and publishers, at a time when the company faced accusations from the right of political bias.

Americans were drifting apart on fundamental societal issues well before the creation of social media, decades of Pew Research Center surveys have shown. But 60% of Americans think the country’s biggest tech companies are helping further divide the country, while only 11% believe they are uniting it, according to a Gallup-Knight survey in March.

Facebook policy chief Joel Kaplan, who played a central role in vetting proposed changes, argued at the time that efforts to make conversations on the platform more civil were “paternalistic,” said people familiar with his comments.

The high number of extremist groups was concerning, the presentation says. Worse was Facebook’s realization that its algorithms were responsible for their growth. The 2016 presentation states that “64% of all extremist group joins are due to our recommendation tools” and that most of the activity came from the platform’s “Groups You Should Join” and “Discover” algorithms: “Our recommendation systems grow the problem.”

In a sign of how far the company has moved, Mr. Zuckerberg in January said he would stand up “against those who say that new types of communities forming on social media are dividing us.” People who have heard him speak privately said he argues social media bears little responsibility for polarization.

Fixing the polarization problem would be difficult, requiring Facebook to rethink some of its core products. Most notably, the project forced Facebook to consider how it prioritized “user engagement”—a metric involving time spent, likes, shares and comments that for years had been the lodestar of its system.

Even before the teams’ 2017 creation, Facebook researchers had found signs of trouble. A 2016 presentation that names as author a Facebook researcher and sociologist, Monica Lee, found extremist content thriving in more than one-third of large German political groups on the platform.

Swamped with racist, conspiracy-minded and pro-Russian content, the groups were disproportionately influenced by a subset of hyperactive users, the presentation notes. Most of them were private or secret.

One proposal Mr. Uribe’s team championed, called “Sparing Sharing,” would have reduced the spread of content disproportionately favored by hyperactive users, according to people familiar with it. Its effects would be heaviest on content favored by users on the far right and left. Middle-of-the-road users would gain influence.

The Common Ground team sought to tackle the polarization problem directly, said people familiar with the team. Data scientists involved with the effort found some interest groups—often hobby-based groups with no explicit ideological alignment—brought people from different backgrounds together constructively. Other groups appeared to incubate impulses to fight, spread falsehoods or demonize a population of outsiders.

Mr. Pariser said that started to change after March 2018, when Facebook got in hot water after disclosing that Cambridge Analytica, the political-analytics startup, improperly obtained Facebook data about tens of millions of people. The shift has gained momentum since, he said: “The internal pendulum swung really hard to ‘the media hates us no matter what we do, so let’s just batten down the hatches.’ ”

Building these features and combating polarization might come at a cost of lower engagement, the Common Ground team warned in a mid-2018 document, describing some of its own proposals as “antigrowth” and requiring Facebook to “take a moral stance.”

Taking action would require Facebook to form partnerships with academics and nonprofits to give credibility to changes affecting public conversation, the document says. This was becoming difficult as the company slogged through controversies after the 2016 presidential election.

Asked to combat fake news, spam, clickbait and inauthentic users, the employees looked for ways to diminish the reach of such ills. One early discovery: Bad behavior came disproportionately from a small pool of hyperpartisan users.

A second finding in the U.S. saw a larger infrastructure of accounts and publishers on the far right than on the far left. Outside observers were documenting the same phenomenon. The gap meant even seemingly apolitical actions such as reducing the spread of clickbait headlines—along the lines of “You Won’t Believe What Happened Next”—affected conservative speech more than liberal content in aggregate.

Every significant new integrity-ranking initiative had to seek the approval of not just engineering managers but also representatives of the public policy, legal, marketing and public-relations departments.

“Engineers that were used to having autonomy maybe over-rotated a bit” after the 2016 election to address Facebook’s perceived flaws, she said. The meetings helped keep that in check. “At the end of the day, if we didn’t reach consensus, we’d frame up the different points of view, and then they’d be raised up to Mark.”

Disapproval from Mr. Kaplan’s team or Facebook’s communications department could scuttle a project, said people familiar with the effort. Negative policy-team reviews killed efforts to build a classification system for hyperpolarized content. Likewise, the Eat Your Veggies process shut down efforts to suppress clickbait about politics more than on other topics.

Under Facebook’s engagement-based metrics, a user who likes, shares or comments on 1,500 pieces of content has more influence on the platform and its algorithms than one who interacts with just 15 posts, allowing “super-sharers” to drown out less-active users

Accounts with hyperactive engagement were far more partisan on average than normal Facebook users, and they were more likely to behave suspiciously, sometimes appearing on the platform as much as 20 hours a day and engaging in spam-like behavior. The behavior suggested some were either people working in shifts or bots.

“We’re explicitly not going to build products that attempt to change people’s beliefs,” one 2018 document states. “We’re focused on products that increase empathy, understanding, and humanization of the ‘other side.’ ”

The debate got kicked up to Mr. Zuckerberg, who heard out both sides in a short meeting, said people briefed on it. His response: Do it, but cut the weighting by 80%. Mr. Zuckerberg also signaled he was losing interest in the effort to recalibrate the platform in the name of social good, they said, asking that they not bring him something like that again.

Mr. Uribe left Facebook and the tech industry within the year. He declined to discuss his work at Facebook in detail but confirmed his advocacy for the Sparing Sharing proposal. He said he left Facebook because of his frustration with company executives and their narrow focus on how integrity changes would affect American politics

While proposals like his did disproportionately affect conservatives in the U.S., he said, in other countries the opposite was true.

The tug of war was resolved in part by the growing furor over the Cambridge Analytica scandal. In a September 2018 reorganization of Facebook’s newsfeed team, managers told employees the company’s priorities were shifting “away from societal good to individual value,” said people present for the discussion. If users wanted to routinely view or post hostile content about groups they didn’t like, Facebook wouldn’t suppress it if the content didn’t specifically violate the company’s rules.
