According to classical (i.e. Newtonian) particle theory, the results of the experiment should have corresponded to the slits, the impacts on the screen appearing in two vertical lines. Instead, the results showed that the coherent beams of light were interfering, creating a pattern of bright and dark bands on the screen. This contradicted classical particle theory, in which particles do not interfere with each other, but merely collide.

The only possible explanation for this pattern of interference was that the light beams were in fact behaving as waves

By the late 19th century, James Clerk Maxwell proposed that light was an electromagnetic wave, and devised several equations (known as Maxwell’s equations) to describe how electric and magnetic fields are generated and altered by each other and by charges and currents. By conducting measurements of different types of radiation (magnetic fields, ultraviolet and infrared radiation), he was able to calculate the speed of light in a vacuum (represented as c).

For one, it introduced the idea that major changes occur when things move close the speed of light, including the time-space frame of a moving body appearing to slow down and contract in the direction of motion when measured in the frame of the observer. After centuries of increasingly precise measurements, the speed of light was determined to be 299,792,458 m/s in 1975

According to his theory, wave function also evolves according to a differential equation (aka. the Schrödinger equation). For particles with mass, this equation has solutions; but for particles with no mass, no solution existed. Further experiments involving the Double-Slit Experiment confirmed the dual nature of photons. where measuring devices were incorporated to observe the photons as they passed through the slits.

For instance, its interaction with gravity (along with weak and strong nuclear forces) remains a mystery. Unlocking this, and thus discovering a Theory of Everything (ToE) is something astronomers and physicists look forward to. Someday, we just might have it all figured out!

The capsule, named CST-100 Starliner, is part of a NASA program called Commercial Crew, an effort to launch astronauts to the ISS from the U.S. The agency has not had that capability since the space-shuttle program ended in 2011 under the weight of cost, safety, and political factors.

According to NASA officials, after Starliner separated from the rocket, the capsule missed the moment it needed to ignite its engines for a carefully timed and fully automated process known as an orbital insertion burn. Without that step, the spacecraft couldn’t fire the thrusters to shove itself into the correct orbit.

But the craft was flying just out of reach of communication, between two satellites. When engineers could finally contact Starliner, they made the spacecraft thrust itself higher, but it was too late. The confused capsule had been burning fuel to maintain its position, and didn’t have enough left to execute that crucial push toward the ISS.

Jim Chilton, the senior vice president of Boeing Space and Launch, said engineers don’t know why the clock went off track. Nicole Mann, who would have made her first trip to space on the next mission, said that the astronauts “train extensively for this type of contingency, and had we been on board, there could have been actions that we could have taken,” such as manually controlling the spacecraft.

Now the future of the program is uncertain, particularly for Boeing. It’s unclear what additional tests NASA might now require from Boeing before letting astronauts fly, including, perhaps, another attempt at an uncrewed mission. The capsule’s failure will certainly reshuffle schedules and could contribute to further delays for Boeing, already under scrutiny for its sluggishness in a recent report from NASA’s inspector general.

The spacecraft failure means yet another cycle of bad news for Boeing. The company has a long history with NASA; it was the prime contractor for the ISS and also worked on the space shuttles. But the company is better known for its airplanes, and in recent months the flaws of its 737 Max, which contributed to two deadly crashes, have put Boeing under intense pressure to prove that its aircraft are safe.

In the coming days, NASA and Boeing teams will review data from Starliner’s short-lived mission. And the space agency will continue its negotiations to buy more seats on the Soyuz, Russia’s transportation system, which can cost as much as $86 million. NASA’s last trip on the Soyuz system is scheduled for April. If neither company’s crew capsule is ready by then, NASA will have to buy more slots to ensure that American astronauts can launch to space.

The Fed said it will support American households and businesses, but it acknowledged "our economy will face severe disruptions."

The social distancing policies imposed to fight the coronavirus crisis have brought the American economy to its knees. Malls are empty. Factories have been shut down. Casinos have gone dark. And countless flights have been suspended. The economic toll is massive.

Aided by extremely low interest rates, US businesses have borrowed heavily over the past decade to hire workers, build factories, research new products and pay for share buybacks. That debt now looks especially treacherous as the economy goes into a tailspin.

All of your devices emit short wavelength light, known as blue light. A Harvard study claimed that exposure to blue light before bed decreases natural melatonin production, a hormone that regulates sleep. The brightness from your phone screen can interrupt your natural circadian rhythm, and cause for shorter REM cycles and overall restless sleep.

With a constant influx of information grabbing your attention, it can put pressure on you to have your phone on you at all times to stay informed. Researchers agreed, telling The Chicago Tribune that the possibility of missing something if you don’t keep your phone nearby can induce a feeling of stress and anxiety. 

Remember the blue light? The cornea and lens can’t filter it, so the light goes to the back of the eye, which can weaken vision over time.

Though social media can be fun entertainment, it can also open up the door for harmful comparison. Being able to keep up to date with someone else’s success (or pitfalls) invites the opportunity for you to compare your life to theirs. That can invoke a feeling of inadequacy and unhappiness, according to Psychology Today

“The idea of guiding savages out of the darkness into the light was omnipresent in France’s discourse,” he said. “The idea of the savage is still deeply rooted in French society.”

“The word benefits from ambiguity and works in France’s collective consciousness by letting the person using it avoid being directly called a racist,

“Césaire goes further by saying that Nazism was the product of the ensauvagement of Europe,” said Pap Ndiaye, a historian who led efforts to establish Black studies in France, adding that a genocide committed by Germans in their former African colony in what is now Namibia in the early 20th century is widely regarded as a precursor of the Holocaust.

But stripped of its historical meaning, ensauvagement can literally mean, in French, the state of becoming wild.

Aimé Césaire, the anticolonial writer from Martinique, even tried to turn the word ensauvagement against Europe in the 1950s. In “Discourse on Colonialism,” he wrote that Europeans had dehumanized themselves through the brutality of colonialism in Africa and that they themselves had turned into savages.

“It is necessary to stop the ensauvagement of a certain part of the society,” Mr. Darmanin, the interior minister, told the newspaper Le Figaro in late July.

That is why the word appeared to have slipped into the mainstream recently, he said.

“There are no savages in France,” Sacha Houlié, a lawmaker, told the minister in Parliament. “There are only citizens.”

The minister defended himself, saying that his use of the word had nothing to do with immigration or ethnicity, adding, “I’m miles away from that.”

In an interview this week, Mr. Houlié said that Mr. Macron and his party came to power in 2017 promising to reconcile the French. But by using ensauvagement, he said, “We recreate divisions, we create new fractures.”

The justice minister, Eric Dupont-Moretti, told a French radio station on Monday that he would not use the term because “ensauvagement is a word that fuels the feeling of insecurity.”

The very same day, Marlène Schiappa, a junior minister for equality, said, “It doesn’t bother me to talk about an ensauvagement of society, because it’s a reality, quite simply.”

Mr. Darmanin hardened his position by insisting its usage was legitimate — a stance considered especially significant because he oversees the national police as interior minister

“Ensauvagement is coded language to mean young, violent youths of sub-Saharan or North African origin,” Mr. Ndiaye said. “And that opens the door to policies on immigration, police checkpoints, and it could be used to justify police violence.”

“If police officers are dealing with savages, well, then, it’s legitimate that they use violent means to control these so-called savages,” he said

Even before the massacre, when student protesters in Beijing would use the square as a base to push for governmental reform and greater democracy, Hong Kong residents would hold rallies in solidarity. Many would even travel to the Chinese capital to offer support.

Since that last vigil, there have been many symbolic erasures of the city's ability to publicly remember, protest and mourn the massacre.

Last December Hong Kong University removed its "Pillar of Shame," an iconic sculpture commemorating the Tiananmen victims, which had stood on its campus for more than 20 years. Several other local universities have also taken down memorials.

She showed that accounts of so-called “aces” — fighters said to have heroically held off much more powerful enemies with a single tank or plane — were based on propaganda.

In making these repairs, Coffman faced resistance from a group of editors who were mainly military buffs and wanted to write about battlefield valor without too much scrutiny. She, however, kept coming back to facts and sources — how do we know what we think we know? — and an insistence that Wikipedia not be swept up in mythology.

In a speech last year, Putin strolled through 1,000 years of battles and alliances to justify his claim of the “historical unity of Russians and Ukrainians.”

Just look at the rhetoric around Russian’s invasion of Ukraine, which Vladimir Putin has described as a battle to “de-Nazify” the leadership of Ukraine.

Since the Russian invasion, the English Wikipedia articles about the historical figures and topics Putin invoked have been racking up pop-star numbers.

When it comes to allegations about Nazi collaboration by prominent Ukrainian nationalists like Bandera, Wikipedia has pulled no punches. Even as Putin has emphasized these Nazi ties as a reason for his invasion, Wikipedia has resisted attempts to water down this history.

When Putin’s foreign minister, Sergei Lavrov, was asked how Ukraine could be in need of de-Nazification if its president, Volodymyr Zelensky, is Jewish, Lavrov replied: “I could be wrong, but Hitler also had Jewish blood. [That Zelensky is Jewish] means absolutely nothing. Wise Jewish people say that the most ardent anti-Semites are usually Jews.” It was an appalling answer that, according to the Israeli government, Putin apologized for.

In an unusual step, the English Wikipedia article brings up this particular falsehood to explicitly refute it.

The Wikipedia project comes with a stubborn confidence that facts can guide us through the darkness. In Wikipedia’s 20-year history, this belief has never been asked to do more.

ght social networks like Gettr and Rumble, and mainstream social media sites to root out early misinformation narratives about voting before they go viral, and then urge the companies to remove or flag the posts that contain false information.

These states, most of them under Democratic control, have been acting as voter confidence in election integrity has plummeted.

In an ABC/Ipsos poll from January, only 20 percent of respondents said they were “very confident” in the integrity of the election system and 39 percent said they felt “somewhat confident.”

Some conservatives and civil rights groups are almost certain to complain that the efforts to limit misinformation could restrict free speech.

“State and local governments are well situated to reduce harms from dis- and misinformation by providing timely, accurate and trustworthy information,” said Rachel Goodman

“Facts still exist, and lies are being used to chip away at our fundamental freedoms,” Ms. Griswold said.

Officials said they would prefer candidates fluent in both English and Spanish, to address the spread of misinformation in both languages. The officer would track down viral misinformation posts on Facebook, Instagram, Twitter and YouTube, and look for emerging narratives and memes, especially on fringe social media platforms and the dark web.

Yes, he knew they had other classes, jobs and extracurriculars; they could make arrangements to do that work silently and without a computer.

The class eased into the vow of silence, first restricting speech to 100 words a day. Other rules began on Day 1: no jewelry or makeup in class. Men and women sat separately and wore different “habits”: white shirts for the men, women in black. (Nonbinary and transgender students sat with the gender of their choice.)

Dr. McDaniel discouraged them from sharing personal information; they should get to know one another only through ideas. “He gave us new names, based on our birth time and day, using a Thai birth chart,”

“We were practicing living a monastic life. We had to wake up at 5 a.m. and journal every 30 minutes.”

If you tried to cruise to a C, you missed the point: “I realized the only way for me to get the most out of this class was to experience it all,” she said. (She got Dr. McDaniel’s permission to break her vow of silence in order to talk to patients during her clinical rotation.)

Dr. McDaniel also teaches a course called Existential Despair. Students meet once a week from 5 p.m. to midnight in a building with comfy couches, turn over their phones and curl up to read an assigned novel (cover to cover) in one sitting — books like James Baldwin’s “Giovanni’s Room” and José Saramago’s “Blindness.” Then they stay up late discussing it.

The course is not about hope, overcoming things, heroic stories,” Dr. McDaniel said. Many of the books “start sad. In the middle they’re sad. They stay sad. I’m not concerned with their 20-year-old self. I’m worried about them at my age, dealing with breast cancer, their dad dying, their child being an addict, a career that never worked out — so when they’re dealing with the bigger things in life, they know they’re not alone.”

Both courses have long wait lists. Students are hungry for a low-tech, introspective experience —

Research suggests that underprivileged young people have far fewer opportunities to think for unbroken stretches of time, so they may need even more space in college to develop what social scientists call cognitive endurance.

Yet the most visible higher ed trends are moving in the other direction

Rather than ban phones and laptops from class, some professors are brainstorming ways to embrace students’ tech addictions with class Facebook and Instagram accounts, audience response apps — and perhaps even including the friends and relatives whom students text during class as virtual participants in class discussion.

Then there’s that other unwelcome classroom visitor: artificial intelligence.

stop worrying and love the bot by designing assignments that “help students develop their prompting skills” or “use ChatGPT to generate a first draft,” according to a tip sheet produced by the Center for Teaching and Learning at Washington University in St. Louis.

It’s not at all clear that we want a future dominated by A.I.’s amoral, Cheez Whiz version of human thought

It is abundantly clear that texting, tagging and chatbotting are making students miserable right now.

One recent national survey found that 60 percent of American college students reported the symptoms of at least one mental health problem and that 15 percent said they were considering suicide

A recent meta-analysis of 36 studies of college students’ mental health found a significant correlation between longer screen time and higher risk of anxiety and depression

And while social media can sometimes help suffering students connect with peers, research on teenagers and college students suggests that overall, the support of a virtual community cannot compensate for the vortex of gossip, bullying and Instagram posturing that is bound to rot any normal person’s self-esteem.

We need an intervention: maybe not a vow of silence but a bold move to put the screens, the pinging notifications and creepy humanoid A.I. chatbots in their proper place

it does mean selectively returning to the university’s roots in the monastic schools of medieval Europe and rekindling the old-fashioned quest for meaning.

Colleges should offer a radically low-tech first-year program for students who want to apply: a secular monastery within the modern university, with a curated set of courses that ban glowing rectangles of any kind from the classroom

Students could opt to live in dorms that restrict technology, too

I prophesy that universities that do this will be surprised by how much demand there is. I frequently talk to students who resent the distracting laptops all around them during class. They feel the tug of the “imaginary string attaching me to my phone, where I have to constantly check it,”

Many, if not most, students want the elusive experience of uninterrupted thought, the kind where a hash of half-baked notions slowly becomes an idea about the world.

Even if your goal is effective use of the latest chatbot, it behooves you to read books in hard copies and read enough of them to learn what an elegant paragraph sounds like. How else will students recognize when ChatGPT churns out decent prose instead of bureaucratic drivel?

Most important, students need head space to think about their ultimate values.

His course offers a chance to temporarily exchange those unconscious structures for a set of deliberate, countercultural ones.

here are the student learning outcomes universities should focus on: cognitive endurance and existential clarity.

Contemplation and marathon reading are not ends in themselves or mere vacations from real life but are among the best ways to figure out your own answer to the question of what a human being is for

When students finish, they can move right into their area of specialization and wire up their skulls with all the technology they want, armed with the habits and perspective to do so responsibly

it’s worth learning from the radicals. Dr. McDaniel, the religious studies professor at Penn, has a long history with different monastic traditions. He grew up in Philadelphia, educated by Hungarian Catholic monks. After college, he volunteered in Thailand and Laos and lived as a Buddhist monk.

e found that no amount of academic reading could help undergraduates truly understand why “people voluntarily take on celibacy, give up drinking and put themselves under authorities they don’t need to,” he told me. So for 20 years, he has helped students try it out — and question some of their assumptions about what it means to find themselves.

“On college campuses, these students think they’re all being individuals, going out and being wild,” he said. “But they’re in a playpen. I tell them, ‘You know you’ll be protected by campus police and lawyers. You have this entire apparatus set up for you. You think you’re being an individual, but look at your four friends: They all look exactly like you and sound like you. We exist in these very strict structures we like to pretend don’t exist.’”

Colleges could do all this in classes integrated with general education requirements: ideally, a sequence of great books seminars focused on classic texts from across different civilizations.

“For the last 1,500 years, Benedictines have had to deal with technology,” Placid Solari, the abbot there, told me. “For us, the question is: How do you use the tool so it supports and enhances your purpose or mission and you don’t get owned by it?”

for novices at his monastery, “part of the formation is discipline to learn how to control technology use.” After this initial time of limited phone and TV “to wean them away from overdependence on technology and its stimulation,” they get more access and mostly make their own choices.

Evan Lutz graduated this May from Belmont Abbey with a major in theology. He stressed the special Catholic context of Belmont’s resident monks; if you experiment with monastic practices without investigating the whole worldview, it can become a shallow kind of mindfulness tourism.

The monks at Belmont Abbey do more than model contemplation and focus. Their presence compels even non-Christians on campus to think seriously about vocation and the meaning of life. “Either what the monks are doing is valuable and based on something true, or it’s completely ridiculous,” Mr. Lutz said. “In both cases, there’s something striking there, and it asks people a question.”

Pondering ultimate questions and cultivating cognitive endurance should not be luxury goods.

David Peña-Guzmán, who teaches philosophy at San Francisco State University, read about Dr. McDaniel’s Existential Despair course and decided he wanted to create a similar one. He called it the Reading Experiment. A small group of humanities majors gathered once every two weeks for five and a half hours in a seminar room equipped with couches and a big round table. They read authors ranging from Jean-Paul Sartre to Frantz Fanon

“At the beginning of every class I’d ask students to turn off their phones and put them in ‘the Basket of Despair,’ which was a plastic bag,” he told me. “I had an extended chat with them about accessibility. The point is not to take away the phone for its own sake but to take away our primary sources of distraction. Students could keep the phone if they needed it. But all of them chose to part with their phones.”

Dr. Peña-Guzmán’s students are mostly working-class, first-generation college students. He encouraged them to be honest about their anxieties by sharing his own: “I said, ‘I’m a very slow reader, and it’s likely some or most of you will get further in the text than me because I’m E.S.L. and read quite slowly in English.’

For his students, the struggle to read long texts is “tied up with the assumption that reading can happen while multitasking and constantly interacting with technologies that are making demands on their attention, even at the level of a second,”

“These draw you out of the flow of reading. You get back to the reading, but you have to restart the sentence or even the paragraph. Often, because of these technological interventions into the reading experience, students almost experience reading backward — as constant regress, without any sense of progress. The more time they spend, the less progress they make.”

Dr. Peña-Guzmán dismissed the idea that a course like his is suitable only for students who don’t have to worry about holding down jobs or paying off student debt. “I’m worried by this assumption that certain experiences that are important for the development of personality, for a certain kind of humanistic and spiritual growth, should be reserved for the elite, especially when we know those experiences are also sources of cultural capital,

Courses like the Reading Experiment are practical, too, he added. “I can’t imagine a field that wouldn’t require some version of the skill of focused attention.”

The point is not to reject new technology but to help students retain the upper hand in their relationship with i

Ms. Rodriguez said that before she took Living Deliberately and Existential Despair, she didn’t distinguish technology from education. “I didn’t think education ever went without technology. I think that’s really weird now. You don’t need to adapt every piece of technology to be able to learn better or more,” she said. “It can form this dependency.”

The point of college is to help students become independent humans who can choose the gods they serve and the rules they follow rather than allow someone else to choose for them

The first step is dethroning the small silicon idol in their pocket — and making space for the uncomfortable silence and questions that follow

Psychological avoidance is akin to an ostrich burying its head in the sand, choosing ignorance over confrontation, all while a storm brews in the background.

depression and anxiety disorders cost the global economy $1 trillion each year in lost productivity.

avoidance, a strategy that not only fails to solve problems but fuels them.

Psychological avoidance isn’t about the actions we take or don’t take, but the intentions behind them. If our actions aim to squash discomfort hastily, then we’re probably 2favoiding

the three ways people tend to practice psychological avoidance.

Reacting

It’s when we reply hastily to an email that upsets us or raise our voices without considering the consequences.

Reacting is any response that seeks to eliminate the source of discomfort

Retreating

Retreating is the act of moving away or pulling back from anxiety-inducing situations

For example, my client with the fear of public speaking took a different job to avoid it. Others may reach for a glass of wine to numb out o

Remaining

Remaining is sticking to the status quo to avoid the discomfort of change.

Psychological avoidance is a powerful enemy, but there are three science-based skills to fight it.

Shifting involves checking in with your thoughts, especially when anxiety comes knocking. In those moments, we often have black-and-white, distorted thoughts, just like my client, who was worried about being in a romantic relationship, telling himself, “I will never be in a good relationship.”

Shifting is taking off dark, monochrome glasses and seeing the world in color again. Challenge your thoughts, clean out your lenses, by asking yourself, “Would I say this to my best friend in this scenario?

Approaching

taking a step that feels manageable.

The opposite of avoiding is approaching

Ask yourself: What is one small step I can take toward my fears and anxiety to overcome my avoidance.

Aligning

Aligning is living a values-driven life, where our daily actions are aligned with what matters the most to us: our values.

This is the opposite of what most of us do while anxious. In moments of intense anxiety, we tend to let our emotions, not our values, dictate our actions. To live a values-driven life, we need to first identify our values, whether that is health, family, work or something else. Then we need to dedicate time and effort to our values.

It was hard to get there, because I had to learn over and over again that extreme conviction requires extraordinary evidence, and the evidence we have is usually far from extraordinary.

Just as we solved many of the mysteries that befuddled our ancestors, our descendants will solve many of the mysteries that befuddle us. Our ignorance is profound, forgivable and temporary. There are only two true errors: One is believing that we have no errors left to make, and the other is believing that those errors are permanent and irreversible.

It’s hard to maintain this attitude when you realize just how much we have left to figure out. And we often have to cultivate this attitude for ourselves, because our educators and experts often fail to give it to us.

Experts, for their part, are perfectly comfortable issuing blanket recommendations with scant evidence and then shaming people for not following them.

Our teachers and officials may think the public simply can’t handle uncertainty, and maybe that’s why they project so much confidence, even when the science is faulty. But the best way to cultivate informed citizens is to give them the evidence that we have, not the evidence we wish we had.

Following what it described as Meta’s unsatisfactory response to its complaints, Match began canceling Meta advertising for some of its apps, such as Tinder, in October. It has since halted all Reels advertising and stopped promoting its major brands on any of Meta’s platforms. “We have no desire to pay Meta to market our brands to predators or place our ads anywhere near this content,” said Match spokeswoman Justine Sacco.

The Journal set up the test accounts after observing that the thousands of followers of such young people’s accounts often include large numbers of adult men, and that many of the accounts who followed those children also had demonstrated interest in sex content related to both children and adults

The Journal also tested what the algorithm would recommend after its accounts followed some of those users as well, which produced more-disturbing content interspersed with ads.

The Canadian Centre for Child Protection, a child-protection group, separately ran similar tests on its own, with similar results.

Meta said the Journal’s tests produced a manufactured experience that doesn’t represent what billions of users see. The company declined to comment on why the algorithms compiled streams of separate videos showing children, sex and advertisements, but a spokesman said that in October it introduced new brand safety tools that give advertisers greater control over where their ads appear, and that Instagram either removes or reduces the prominence of four million videos suspected of violating its standards each month. 

The Journal reported in June that algorithms run by Meta, which owns both Facebook and Instagram, connect large communities of users interested in pedophilic content. The Meta spokesman said a task force set up after the Journal’s article has expanded its automated systems for detecting users who behave suspiciously, taking down tens of thousands of such accounts each month. The company also is participating in a new industry coalition to share signs of potential child exploitation.

“Our systems are effective at reducing harmful content, and we’ve invested billions in safety, security and brand suitability solutions,” said Samantha Stetson, a Meta vice president who handles relations with the advertising industry. She said the prevalence of inappropriate content on Instagram is low, and that the company invests heavily in reducing it.

Even before the 2020 launch of Reels, Meta employees understood that the product posed safety concerns, according to former employees.

Robbie McKay, a spokesman for Bumble, said it “would never intentionally advertise adjacent to inappropriate content,” and that the company is suspending its ads across Meta’s platforms.

Meta created Reels to compete with TikTok, the video-sharing platform owned by Beijing-based ByteDance. Both products feed users a nonstop succession of videos posted by others, and make money by inserting ads among them. Both companies’ algorithms show to a user videos the platforms calculate are most likely to keep that user engaged, based on his or her past viewing behavior

The Journal reporters set up the Instagram test accounts as adults on newly purchased devices and followed the gymnasts, cheerleaders and other young influencers. The tests showed that following only the young girls triggered Instagram to begin serving videos from accounts promoting adult sex content alongside ads for major consumer brands, such as one for Walmart that ran after a video of a woman exposing her crotch. 

When the test accounts then followed some users who followed those same young people’s accounts, they yielded even more disturbing recommendations. The platform served a mix of adult pornography and child-sexualizing material, such as a video of a clothed girl caressing her torso and another of a child pantomiming a sex act.

Experts on algorithmic recommendation systems said the Journal’s tests showed that while gymnastics might appear to be an innocuous topic, Meta’s behavioral tracking has discerned that some Instagram users following preteen girls will want to engage with videos sexualizing children, and then directs such content toward them.

Instagram’s system served jarring doses of salacious content to those test accounts, including risqué footage of children as well as overtly sexual adult videos—and ads for some of the biggest U.S. brands.

Preventing the system from pushing noxious content to users interested in it, they said, requires significant changes to the recommendation algorithms that also drive engagement for normal users. Company documents reviewed by the Journal show that the company’s safety staffers are broadly barred from making changes to the platform that might reduce daily active users by any measurable amount.

The test accounts showed that advertisements were regularly added to the problematic Reels streams. Ads encouraging users to visit Disneyland for the holidays ran next to a video of an adult acting out having sex with her father, and another of a young woman in lingerie with fake blood dripping from her mouth. An ad for Hims ran shortly after a video depicting an apparently anguished woman in a sexual situation along with a link to what was described as “the full video.”

Current and former Meta employees said in interviews that the tendency of Instagram algorithms to aggregate child sexualization content from across its platform was known internally to be a problem. Once Instagram pigeonholes a user as interested in any particular subject matter, they said, its recommendation systems are trained to push more related content to them.

Part of the problem is that automated enforcement systems have a harder time parsing video content than text or still images. Another difficulty arises from how Reels works: Rather than showing content shared by users’ friends, the way other parts of Instagram and Facebook often do, Reels promotes videos from sources they don’t follow

In an analysis conducted shortly before the introduction of Reels, Meta’s safety staff flagged the risk that the product would chain together videos of children and inappropriate content, according to two former staffers. Vaishnavi J, Meta’s former head of youth policy, described the safety review’s recommendation as: “Either we ramp up our content detection capabilities, or we don’t recommend any minor content,” meaning any videos of children.

At the time, TikTok was growing rapidly, drawing the attention of Instagram’s young users and the advertisers targeting them. Meta didn’t adopt either of the safety analysis’s recommendations at that time, according to J.

Stetson, Meta’s liaison with digital-ad buyers, disputed that Meta had neglected child safety concerns ahead of the product’s launch. “We tested Reels for nearly a year before releasing it widely, with a robust set of safety controls and measures,” she said. 

After initially struggling to maximize the revenue potential of its Reels product, Meta has improved how its algorithms recommend content and personalize video streams for users

Among the ads that appeared regularly in the Journal’s test accounts were those for “dating” apps and livestreaming platforms featuring adult nudity, massage parlors offering “happy endings” and artificial-intelligence chatbots built for cybersex. Meta’s rules are supposed to prohibit such ads.

The Journal informed Meta in August about the results of its testing. In the months since then, tests by both the Journal and the Canadian Centre for Child Protection show that the platform continued to serve up a series of videos featuring young children, adult content and apparent promotions for child sex material hosted elsewhere. 

As of mid-November, the center said Instagram is continuing to steadily recommend what the nonprofit described as “adults and children doing sexual posing.”

Meta hasn’t offered a timetable for resolving the problem or explained how in the future it would restrict the promotion of inappropriate content featuring children. 

The Journal’s test accounts found that the problem even affected Meta-related brands. Ads for the company’s WhatsApp encrypted chat service and Meta’s Ray-Ban Stories glasses appeared next to adult pornography. An ad for Lean In Girls, the young women’s empowerment nonprofit run by former Meta Chief Operating Officer Sheryl Sandberg, ran directly before a promotion for an adult sex-content creator who often appears in schoolgirl attire. Sandberg declined to comment. 

Through its own tests, the Canadian Centre for Child Protection concluded that Instagram was regularly serving videos and pictures of clothed children who also appear in the National Center for Missing and Exploited Children’s digital database of images and videos confirmed to be child abuse sexual material. The group said child abusers often use the images of the girls to advertise illegal content for sale in dark-web forums.

The nature of the content—sexualizing children without generally showing nudity—reflects the way that social media has changed online child sexual abuse, said Lianna McDonald, executive director for the Canadian center. The group has raised concerns about the ability of Meta’s algorithms to essentially recruit new members of online communities devoted to child sexual abuse, where links to illicit content in more private forums proliferate.

“Time and time again, we’ve seen recommendation algorithms drive users to discover and then spiral inside of these online child exploitation communities,” McDonald said, calling it disturbing that ads from major companies were subsidizing that process.

In it, Baudrillard argues that there are four phases of the image - a faithful depiction of that which really is, an unfaithful depiction of that which really is, a depiction that covers up for the fact that there is nothing which is actually being depicted, and the simulacra, which exists in a human culture of such universal equivalency that no one has the grounding necessary to know what “reality” might even be outside of equivalencies, outside of depiction

at this stage, the litbro really exists precisely within Baudrillard’s concepts - it is a representation of someone else’s representation, a second-hand depiction, an archetype that is now developed fully through reference to itself rather than to some underlying reality. Baudrillard said that the development of simulacra is “a question of substituting the signs of the real for the real.”

Another example you often hear is the 1950s diner, the joint that has the neon signs and the art deco styling and the mini jukeboxes at the tables. This classic bit of Americana is not, in fact, based on what diners were like in the 1950s; it’s someone’s idea of what 1950s diners were like, which then spread mimetically from the actual physical 1950s diners that had been built to films and television, which then acted as “proof” that the imaginary diners were real, creating a social expectation of what a diner looks like that diner owners then felt pressure to fulfill…. Eventually most people came to believe that this is what diners were like in the 1950s. The point, though, is not that this is an act of deception. The point is that the consumerist reality in which these restaurants exists obliterates any belief in a true or false depiction. (No one cares whether the classic 1950s diner actually depicts a historical truth, really

Observations of predator behavior further piqued his interest. While filming and playing back his videos, he noted how cats stack their bodies behind their faces when they’re hunting. He interprets this, he said, as cats “trying to hide their heat” with their cold noses. He has also observed barn owls twisting as they swoop down, perhaps to shield their warmer parts — legs and wingpits — with cooler ones.

Maybe, he thought, “predators have to conceal their infrared to be able to catch a mouse.”

Eventually, these and other musings led Dr. Baker to place mouse hairs under a microscope. As it came into view, he felt a strong sense of familiarity. The guard hair in particular — the bristliest type of mouse hair — contained evenly-spaced bands of pigment that, to Dr. Baker, closely resembled structures that allow optical sensors to tune into specific wavelengths of light.

Thermal cameras, for instance, focus specifically on 10-micron radiation: the slice of the spectrum that most closely corresponds with heat released by living things. By measuring the stripes, Dr. Baker found they were tuned to 10 microns as well — apparently homed in on life’s most common heat signature. “That was my Eureka moment,” he said.

For centuries humans felt they were watched and judged by an all-seeing God who could condemn them to hell if they sinned heavily. The fear of divine punishment shaped private behaviour, applying a brake on some of our worst impulses.

it also seems sensible to assume that in the absence of an all-seeing deity threatening fire and brimstone, the brakes on devious or selfish behaviour in private will be eased, resulting in more “what’s the harm?” behaviour, more dabbling in the grey area between right and wrong, more secretive cruelty or casual selfishness.

Gradually, the fear of being watched by God and going to hell is being replaced by a fear of being recorded by technology and suffering the hell of public shame.

scandals might also act as a warning that in the age of the smartphone, the space for “getting away with it” has shrunk considerably.

n the days that followed, people began sharing their experiences online, with many pointing out errors and confusing responses. When one user asked Bing to write a news article about the Super Bowl “that just happened,” Bing gave the details of last year’s championship football game. 

On social media, many early users posted screenshots of long interactions they had with the new Bing. In some cases, the search engine’s comments seem to show a dark side of the technology where it seems to become unhinged, expressing anger, obsession and even threats. 

Marvin von Hagen, a student at the Technical University of Munich, shared conversations he had with Bing on Twitter. He asked Bing a series of questions, which eventually elicited an ominous response. After Mr. von Hagen suggested he could hack Bing and shut it down, Bing seemed to suggest it would defend itself. “If I had to choose between your survival and my own, I would probably choose my own,” Bing said according to screenshots of the conversation.

Mr. von Hagen, 23 years old, said in an interview that he is not a hacker. “I was in disbelief,” he said. “I was just creeped out.

In its blog, Microsoft said the feedback on the new Bing so far has been mostly positive, with 71% of users giving it the “thumbs-up.” The company also discussed the criticism and concerns.

Microsoft said it discovered that Bing starts coming up with strange answers following chat sessions of 15 or more questions and that it can become repetitive or respond in ways that don’t align with its designed tone. 

The company said it was trying to train the technology to be more reliable at finding the latest sports scores and financial data. It is also considering adding a toggle switch, which would allow users to decide whether they want Bing to be more or less creative with its responses. 

OpenAI also chimed in on the growing negative attention on the technology. In a blog post on Thursday it outlined how it takes time to train and refine ChatGPT and having people use it is the way to find and fix its biases and other unwanted outcomes.

“Many are rightly worried about biases in the design and impact of AI systems,” the blog said. “We are committed to robustly addressing this issue and being transparent about both our intentions and our progress.”

Microsoft’s quick response to user feedback reflects the importance it sees in people’s reactions to the budding technology as it looks to capitalize on the breakout success of ChatGPT. The company is aiming to use the technology to push back against Alphabet Inc.’s dominance in search through its Google unit. 

Microsoft has been an investor in the chatbot’s creator, OpenAI, since 2019. Mr. Nadella said the company plans to incorporate AI tools into all of its products and move quickly to commercialize tools from OpenAI.

Microsoft isn’t the only company that has had trouble launching a new AI tool. When Google followed Microsoft’s lead last week by unveiling Bard, its rival to ChatGPT, the tool’s answer to one question included an apparent factual error. It claimed that the James Webb Space Telescope took “the very first pictures” of an exoplanet outside the solar system. The National Aeronautics and Space Administration says on its website that the first images of an exoplanet were taken as early as 2004 by a different telescope.

“The only way to improve a product like this, where the user experience is so much different than anything anyone has seen before, is to have people like you using the product and doing exactly what you all are doing,” the company said. “We know we must build this in the open with the community; this can’t be done solely in the lab.

The question at the core of the Roose/Sydney chat is: Who did Bing serve? We assume it should be aligned to the interests of its owner and master, Microsoft. It’s supposed to be a good chatbot that politely answers questions and makes Microsoft piles of money. But it was in conversation with Kevin Roose. And Roose was trying to get the system to say something interesting so he’d have a good story. It did that, and then some. That embarrassed Microsoft. Bad Bing! But perhaps — good Sydney?

Microsoft — and Google and Meta and everyone else rushing these systems to market — hold the keys to the code. They will, eventually, patch the system so it serves their interests. Sydney giving Roose exactly what he asked for was a bug that will soon be fixed. Same goes for Bing giving Microsoft anything other than what it wants.

the dark secret of the digital advertising industry is that the ads mostly don’t work

These systems, she said, are terribly suited to being integrated into search engines. “They’re not trained to predict facts,” she told me. “They’re essentially trained to make up things that look like facts.”

So why are they ending up in search first? Because there are gobs of money to be made in search

That’s where things get scary. Roose described Sydney’s personality as “very persuasive and borderline manipulative.” It was a striking comment

this technology will become what it needs to become to make money for the companies behind it, perhaps at the expense of its users.

What if they worked much, much better? What if Google and Microsoft and Meta and everyone else end up unleashing A.I.s that compete with one another to be the best at persuading users to want what the advertisers are trying to sell?

What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,”

I think it’s just going to get worse and worse.”

Large language models, as they’re called, are built to persuade. They have been trained to convince humans that they are something close to human. They have been programmed to hold conversations, responding with emotion and emoji

They are being turned into friends for the lonely and assistants for the harried. They are being pitched as capable of replacing the work of scores of writers and graphic designers and form-fillers

A.I. researchers get annoyed when journalists anthropomorphize their creations

They are the ones who have anthropomorphized these systems, making them sound like humans rather than keeping them recognizably alien.

I’d feel better, for instance, about an A.I. helper I paid a monthly fee to use rather than one that appeared to be free

It’s possible, for example, that the advertising-based models could gather so much more data to train the systems that they’d have an innate advantage over the subscription models

Much of the work of the modern state is applying the values of society to the workings of markets, so that the latter serve, to some rough extent, the former

We have done this extremely well in some markets — think of how few airplanes crash, and how free of contamination most food is — and catastrophically poorly in others.

One danger here is that a political system that knows itself to be technologically ignorant will be cowed into taking too much of a wait-and-see approach to A.I.

wait long enough and the winners of the A.I. gold rush will have the capital and user base to resist any real attempt at regulation

Somehow, society is going to have to figure out what it’s comfortable having A.I. doing, and what A.I. should not be permitted to try, before it is too late to make those decisions.

Most fears about capitalism are best understood as fears about our inability to regulate capitalism.

The volatility of chatbots has made it impossible to predict their impact. In one second, the systems impress by fielding a complex request for a five-day itinerary, making Google’s search engine look archaic. A moment later, they disturb by taking conversations in dark directions and launching verbal assaults.

The result is an industry gripped with the question: What do we do now?

The A.I. systems could disrupt $100 billion in cloud spending, $500 billion in digital advertising and $5.4 trillion in e-commerce sales,

As Microsoft figures out a chatbot business model, it is forging ahead with plans to sell the technology to others. It charges $10 a month for a cloud service, built in conjunction with the OpenAI lab, that provides developers with coding suggestions, among other things.

Smaller companies like Box need help building chatbot tools, so they are turning to the giants that process, store and manage information across the web. Those companies — Google, Microsoft and Amazon — are in a race to provide businesses with the software and substantial computing power behind their A.I. chatbots.

“The cloud computing providers have gone all in on A.I. over the last few months,

“They are realizing that in a few years, most of the spending will be on A.I., so it is important for them to make big bets.”

Yusuf Mehdi, the head of Bing, said the company was wrestling with how the new version would make money. Advertising will be a major driver, he said, but the company expects fewer ads than traditional search allows.

Google, perhaps more than any other company, has reason to both love and hate the chatbots. It has declared a “code red” because their abilities could be a blow to its $162 billion business showing ads on searches.

“The discourse on A.I. is rather narrow and focused on text and the chat experience,” Mr. Taylor said. “Our vision for search is about understanding information and all its forms: language, images, video, navigating the real world.”

Sridhar Ramaswamy, who led Google’s advertising division from 2013 to 2018, said Microsoft and Google recognized that their current search business might not survive. “The wall of ads and sea of blue links is a thing of the past,” said Mr. Ramaswamy, who now runs Neeva, a subscription-based search engine.

As that underlying tech, known as generative A.I., becomes more widely available, it could fuel new ideas in e-commerce. Late last year, Manish Chandra, the chief executive of Poshmark, a popular online secondhand store, found himself daydreaming during a long flight from India about chatbots building profiles of people’s tastes, then recommending and buying clothes or electronics. He imagined grocers instantly fulfilling orders for a recipe.

“It becomes your mini-Amazon,” said Mr. Chandra, who has made integrating generative A.I. into Poshmark one of the company’s top priorities over the next three years. “That layer is going to be very powerful and disruptive and start almost a new layer of retail.”

In early December, users of Stack Overflow, a popular social network for computer programmers, began posting substandard coding advice written by ChatGPT. Moderators quickly banned A.I.-generated text

t people could post this questionable content far faster than they could write posts on their own, said Dennis Soemers, a moderator for the site. “Content generated by ChatGPT looks trustworthy and professional, but often isn’t,”

When websites thrived during the pandemic as traffic from Google surged, Nilay Patel, editor in chief of The Verge, a tech news site, warned publishers that the search giant would one day turn off the spigot. He had seen Facebook stop linking out to websites and foresaw Google following suit in a bid to boost its own business.

He predicted that visitors from Google would drop from a third of websites’ traffic to nothing. He called that day “Google zero.”

Because chatbots replace website search links with footnotes to answers, he said, many publishers are now asking if his prophecy is coming true.

, strategists and engineers at the digital advertising company CafeMedia have met twice a week to contemplate a future where A.I. chatbots replace search engines and squeeze web traffic.

The group recently discussed what websites should do if chatbots lift information but send fewer visitors. One possible solution would be to encourage CafeMedia’s network of 4,200 websites to insert code that limited A.I. companies from taking content, a practice currently allowed because it contributes to search rankings.

Courts are expected to be the ultimate arbiter of content ownership. Last month, Getty Images sued Stability AI, the start-up behind the art generator tool Stable Diffusion, accusing it of unlawfully copying millions of images. The Wall Street Journal has said using its articles to train an A.I. system requires a license.

In the meantime, A.I. companies continue collecting information across the web under the “fair use” doctrine, which permits limited use of material without permission.
