if this were any normal product we’d assume that people love it and are grateful to the companies that provide it to them — without charge, no less.

Turning to their own lives, 52 percent of the total sample say social media has benefited their lives, and 29 percent say it has hurt them personally.

Is it more like walkie-talkies, where hardly anyone wished they had never been invented? Or is it more like cigarettes, where smokers often say they enjoy smoking, but more than 71 percent of smokers (in one 2014 survey) regret ever starting?

So what does Gen Z really think about social media?

We recently collaborated on a nationally representative survey of 1,006 Gen Z adults (ages 18-27). We asked them online about their own social media use, about their views on the effects of social media on themselves and on society and about what kinds of reforms they’d support.

First, the number of hours spent on social media each day is astonishing. Over 60 percent of our respondents said they spend at least four hours a day, with 23 percent saying they spend seven or more hours each day using social media.

Second, our respondents recognize the harm that social media causes society, with 60 percent saying it has a negative impact (versus 32 percent who say it has a positive impact).

This is especially painful for adolescents, whose social networks have migrated, since the early 2010s, onto a few giant platforms. Nearly all American teenagers use social media regularly, and they spend an average of nearly five hours a day just on these platforms.

Although the percentage citing specific personal benefits was usually higher than those citing harms, this was less true for women and L.G.B.T.Q. respondents

For example, 37 percent of respondents said social media had a negative impact on their emotional health, with significantly more women (44 percent) than men (31 percent), and with more L.G.B.T.Q. (47 percent) than non-L.G.B.T.Q. respondents (35 percent) saying so. We have found this pattern — that social media disproportionately hurts young people from historically disadvantaged groups — in a wide array of surveys.

And even when more respondents cite more benefits than harms, that does not justify the unregulated distribution of a consumer product that is hurting — damaging, really — millions of children and young adults

Our survey shows that many Gen Z-ers see substantial dangers and costs from social media. A majority of them want better and safer platforms, and many don’t think these platforms are suitable for children

If any other consumer product was causing serious harm to more than one out of every 10 of its young users, there would be a tidal wave of state and federal legislation to ban or regulate it.

Turning to the ultimate test of regret versus gratitude: We asked respondents to tell us, for various platforms and products, if they wished that it “was never invented.”

Five items produced relatively low levels of regret: YouTube (15 percent), Netflix (17 percent), the internet itself (17 percent), messaging apps (19 percent) and the smartphone (21 percent).

We interpret these low numbers as indicating that Gen Z does not heavily regret the basic communication, storytelling and information-seeking functions of the internet.

responses were different for the main social media platforms that parents and Gen Z itself worry about most. Many more respondents wished these products had never been invented: Instagram (34 percent), Facebook (37 percent), Snapchat (43 percent), and the most regretted platforms of all: TikTok (47 percent) and X/Twitter (50 percent).

We’re not just talking about sad feelings from FOMO or social comparison. We’re talking about a range of documented risks that affect heavy users, including sleep deprivation, body image distortion, depression, anxiety, exposure to content promoting suicide and eating disorders, sexual predation and sextortion, and “problematic use,” which is the term psychologists use to describe compulsive overuse that interferes with success in other areas of life.

Forty-five percent of Gen Z-ers report that they “would not or will not allow my child to have a smartphone before reaching high school age (i.e. about 14 years old)”

57 percent support the idea that parents should restrict their child’s access to smartphones before that age

Although only 36 percent support social media bans for those under the age of 16, 69 percent support a law requiring social media companies to develop a child-safe option for users under 18.

This high level of support is true across race, gender, social class and sexual orientatio

it has important implications for the House of Representatives, which is considering just such a bill, the Kids Online Safety Act. The bill would, among other things, disable addictive product features, require tech companies to offer young users the option to use non-personalized algorithmic feeds and mandate that platforms default to the safest settings possible for accounts believed to be held by minors.

imagine if walkie-talkies were harming millions of young people. Imagine if more than a third of young people wished that walkie-talkies didn’t exist, yet still felt compelled to use them for five hours every day.

We’d insist that the manufacturers make their products safer and less addictive for kids. Social media companies must be held to the same standard: Either fix their products to ensure the safety of young users or stop providing them to children altogether.

The human problem-solvers — 609 high school students from 108 countries — won 58 gold medals, 123 silver and 145 bronze. The A.I. performed at the level of a silver medalist, solving four out of six problems for a total of 28 points. It was the first time that A.I. has achieved a medal-worthy performance on an Olympiad’s problems.

Nonetheless, Dr. Kohli described the result as a “phase transition” — a transformative change — “in the use of A.I. in mathematics and the ability of A.I. systems to do mathematics.”

Dr. Gowers added in an email: “I was definitely impressed.” The lab had discussed its Olympiad ambitions with him a couple of weeks beforehand, so “my expectations were quite high,” he said. “But the program met them, and in one or two instances significantly surpassed them.” The program found the “magic keys” that unlocked the problems, he said.

Haojia Shi, a student from China, ranked No. 1 and was the only competitor to earn a perfect score — 42 points for six problems; each problem is worth seven points for a full solution. The U.S. team won first place with 192 points; China placed second with 190.

The Google system earned its 28 points for fully solving four problems — two in algebra, one in geometry and one in number theory. (It flopped at two combinatorics problems.) The system was allowed unlimited time; for some problems it took up to three days. The students were allotted only 4.5 hours per exam.

“The fact that we’ve reached this threshold, where it’s even possible to tackle these problems at all, is what represents a step-change in the history of mathematics,” he added. “And hopefully it’s not just a step-change in the I.M.O., but also represents the point at which we went from computers only being able to prove very, very simple things toward computers being able to prove things that humans can’t.”

“Mathematics requires this interesting combination of abstract, precise and creative reasoning,” Dr. Davies said. In part, he noted, this repertoire of abilities is what makes math a good litmus test for the ultimate goal: reaching so-called artificial general intelligence, or A.G.I., a system with capabilities ranging from emerging to competent to virtuoso to superhuman

One approach was an informal reasoning system, expressed in natural language. This system leveraged Gemini, Google’s large language model. It used the English corpus of published problems and proofs and the like as training data.

Dr. Hubert’s team developed a new model that is comparable but more generalized. Named AlphaProof, it is designed to engage with a broad range of mathematical subjects. All told, AlphaGeometry and AlphaProof made use of a number of different A.I. technologies.

In January, a Google DeepMind system named AlphaGeometry solved a sampling of Olympiad geometry problems at nearly the level of a human gold medalist. “AlphaGeometry 2 has now surpassed the gold medalists in solving I.M.O. problems,” Thang Luong, the principal investigator, said in an email.

The informal system excels at identifying patterns and suggesting what comes next; it is creative and talks about ideas in an understandable way. Of course, large language models are inclined to make things up — which may (or may not) fly for poetry and definitely not for math. But in this context, the L.L.M. seems to have displayed restraint; it wasn’t immune to hallucination, but the frequency was reduced.

Another approach was a formal reasoning system, based on logic and expressed in code. It used theorem prover and proof-assistant software called Lean, which guarantees that if the system says a proof is correct, then it is indeed correct. “We can exactly check that the proof is correct or not,” Dr. Hubert said. “Every step is guaranteed to be logically sound.”

Another crucial component was a reinforcement learning algorithm in the AlphaGo and AlphaZero lineage. This type of A.I. learns by itself and can scale indefinitely, said Dr. Silver, who is Google DeepMind’s vice-president of reinforcement learning. Since the algorithm doesn’t require a human teacher, it can “learn and keep learning and keep learning until ultimately it can solve the hardest problems that humans can solve,” he said. “And then maybe even one day go beyond those.”

Dr. Hubert added, “The system can rediscover knowledge for itself.” That’s what happened with AlphaZero: It started with zero knowledge, Dr. Hubert said, “and by just playing games, and seeing who wins and who loses, it could rediscover all the knowledge of chess. It took us less than a day to rediscover all the knowledge of chess, and about a week to rediscover all the knowledge of Go. So we thought, Let’s apply this to mathematics.”

Dr. Gowers doesn’t worry — too much — about the long-term consequences. “It is possible to imagine a state of affairs where mathematicians are basically left with nothing to do,” he said. “That would be the case if computers became better, and far faster, at everything that mathematicians currently do.”

“There still seems to be quite a long way to go before computers will be able to do research-level mathematics,” he added. “It’s a fairly safe bet that if Google DeepMind can solve at least some hard I.M.O. problems, then a useful research tool can’t be all that far away.”

A really adept tool might make mathematics accessible to more people, speed up the research process, nudge mathematicians outside the box. Eventually it might even pose novel ideas that resonate.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

One of the key themes in "Wise Animals" is the idea that technology is far from neutral. Chatfield argues that the way innovation has progressed was not the only possible path and that we must keep an open mind about the possibilities

“Empirical data do not support the conclusion of a crisis of public trust in science,” Naomi Oreskes and Erik M. Conway, historians of science at Harvard and Caltech, write in their 2022 article “From Anti-Government to Anti-Science: Why Conservatives Have Turned Against Science.” But the data “do support the conclusion of a crisis of conservative trust in science.”

Between 2018 and 2021, the General Social Survey found that the spread between the percentage of Democrats and Republicans who said they have “a great deal of confidence in the scientific community” rose to 33 points (65-32) from 13 points (54-41).

“During the Covid-19 pandemic,” the authors write,medicine and public health more broadly became politicized, with the internet amplifying public figures and even physicians encouraging individuals not to trust the advice of public health experts and scientists. As such, the pandemic may have represented a turning point in trust, with a profession previously seen as trustworthy increasingly subject to doubt.

Consider in 2000, 46 percent of Democrats and, almost equivalently, 47 percent of Republicans expressed a great deal of confidence in scientists. In 2022, these respective percentages were 53 percent and 28 percent. In twenty years, a partisan chasm in trust (a 25-percentage point gap) emerged.

Matthew Dallek, a political historian at George Washington University, wrote

Distrust of science is arguably the greatest hindrance to societal action to stem numerous threats to the lives of Americans and people worldwide

Some people suffer from poor dental health in part because their parents distrusted fluoridation of drinking water. The national failure to invest until recently in combating climate change has raised the odds of pandemics, made diseases more rampant, destabilized entire regions, and spurred a growing crisis of migration and refugees that has helped popularize far-right nativism in many Western democracies.

Donald Trump’s MAGA movement, Dallek argued,turbocharged anti-science conspiracy theories and attitudes on the American right, vaulting them to an even more influential place in American politics. Bogus notions — vaccines may cause autism, hydroxychloroquine may cure Covid, climate change isn’t real — have become linchpins of MAGA-era conservatism.

People look to their political leaders to provide them with information (“cues” or “heuristics”) about how they ought to think about complex science-related issues.

The direction of the partisan response, Bardon wrote, is driven by “who the facts are favoring, and science currently favors bad news for the industrial status quo.

The roots of the divergence, however, go back at least 50 years with the creation of the Environmental Protection Agency and the Occupational Safety and Health Administration in 1970, along with the enactment that same year of the Clean Air Act and two years later of the Clean Water Act.

These pillars of the regulatory state were, and still are, deeply dependent on scientific research to set rules and guidelines. All would soon be seen as adversaries of the sections of the business community that are closely allied with the Republican Party

These agencies and laws fostered the emergence of what Gordon Gauchat, a professor of sociology at the University of Wisconsin at Milwaukee, calls “regulatory science.” This relatively new role thrust science into the center of political debates with the result that federal agencies like the E.P.A. and OSHA “are considered adversarial to corporate interests. Regulatory science directly connects to policy management and, therefore, has become entangled in policy debates that are unavoidably ideological.”

In their 2022 article, Oreskes and Conway, write that conservatives’ hostility to sciencetook strong hold during the Reagan administration, largely in response to scientific evidence of environmental crises that invited governmental response. Thus, science — particularly environmental and public health science — became the target of conservative anti-regulatory attitudes.

“in every sociodemographic group in this survey study among 443, 2f455 unique respondents aged 18 years or older residing in the U.S., trust in physicians and hospitals decreased substantially over the course of the pandemic, from 71.5 percent in April 2020 to 40.1 percent in January 2024.”

religious and political skepticism of science have become mutually constitutive and self-reinforcing.

and thus secular science, concentrate in the Democratic Party. The process of party-sorting along religious lines has helped turn an ideological divide over science into a partisan one.

As partisan elites have staked out increasingly clear positions on issues related to climate change, vaccine hesitancy, and other science-related policy issues, the public has polarized in response.

Oreskes and Conway argue that the strength of the anti-science movement was driven by the alliance in the Reagan years between corporate interests and the ascendant religious right, which became an arm of the Republican Party as it supported creationism

This creates a feedback cycle, whereby — once public opinion polarizes about science-related issues — political elites have an electoral incentive to appeal to that polarization, both in the anti-science rhetoric they espouse and in expressing opposition to evidence-based policies.

In a demographically representative survey of 1,959 U.S. adults, I tracked how intentions to receive preventative cancer vaccines (currently undergoing clinical trials) vary by partisan identity. I find that cancer vaccines are already politically polarizing, such that Republicans are less likely than Democrats to intend to vaccinate.

Another key factor driving a wedge between the two parties over the trustworthiness of science is the striking partisan difference over risk tolerance and risk aversion.

Their conclusion: “We find, on average, that women are more risk averse than men.”

white males were more sympathetic with hierarchical, individualistic, and anti-egalitarian views, more trusting of technology managers, less trusting of government, and less sensitive to potential stigmatization of communities from hazards

The group with the consistently lowest risk perceptions across a range of hazards was white males.

Furthermore, we found sizable differences between white males and other groups in sociopolitical attitudes.

When asked whether “electrons are smaller than atoms” and “what gas makes up most of the earth’s atmosphere: hydrogen, nitrogen, carbon dioxide or oxygen,” almost identical shares of religious and nonreligious men and women who scored high on measures of scientific knowledge gave correct answers to the questions.

These positions suggest greater confidence in experts and less confidence in public-dominated social processes.

In other words, white men — the dominant constituency of the Republican Party, in what is known in the academic literature as “the white male effect” — are relatively risk tolerant and thus more resistant (or less committed) to science-based efforts to reduce the likelihood of harm to people or to the environment

major Democratic constituencies are more risk averse and supportive of harm-reducing policies.

Insofar as people tend to accept scientific findings that align with their political beliefs and disregard those that contradict them, political views carry more weight than knowledge of science.

comparing the answers to scientific questions among religious and nonreligious respondents revealed significant insight into differing views of what is true and what is not.

Our survey revealed that men rate a wide range of hazards as lower in risk than do women. Our survey also revealed that whites rate risks lower than do nonwhites

However, when asked “human beings, as we know them today, developed from earlier species of animals, true or false,” the religious students high in scientific literacy scored far below their nonreligious counterparts.

the evolution question did not measure scientific knowledge but instead was a gauge of “something else: a form of cultural identity.”

Kahan then cites a survey that asked “how much risk do you believe climate change poses to human health, safety or prosperity?” The survey demonstrated a striking correlation between political identity and the level of perceived risk: Strong Democrats saw severe risk potential; strong Republicans close to none.

the different responses offered by religious and nonreligious respondents to the evolution question were similar to the climate change responses in that they were determined by “cultural identity” — in this case, political identity.

Indeed, the inference can be made even stronger by substituting for, or fortifying political outlooks with, even more discerning cultural identity indicators, such as cultural worldviews and their interaction with demographic characteristics such as race and gender. In sum, whether people “believe in” climate change, like whether they “believe in” evolution, expresses who they are.

2023 PNAS paper, “Prosocial Motives Underlie Scientific Censorship by Scientists,” Cory J. Clark, Steven Pinker, David Buss, Philip Tetlock, David Geary and 34 others make the case that the scientific community at times censors itself

“Our analysis suggests that scientific censorship is often driven by scientists, who are primarily motivated by self-protection, benevolence toward peer scholars, and prosocial concerns for the well-being of human social groups.”

Clark and her co-authors argue that

Prosocial motives for censorship may explain four observations: 1) widespread public availability of scholarship coupled with expanding definitions of harm has coincided with growing academic censorship; 2) women, who are more harm-averse and more protective of the vulnerable than men, are more censorious; 3) although progressives are often less censorious than conservatives, egalitarian progressives are more censorious of information perceived to threaten historically marginalized groups; and 4) academics in the social sciences and humanities (disciplines especially relevant to humans and social policy) are more censorious and more censored than those in STEM.

The explicit politicization of academic institutions, including science journals, academic professional societies, universities, and university departments, is likely one causal factor that explains reduced trust in science.

Dietram A. Scheufele, who is a professor in science communication at the University of Wisconsin, was sharply critical of what he calls the scientific community’s “self-inflicted wounds”:

One is the sometimes gratuitous tendency among scientists to mock groups in society whose values we see as misaligned with our own. This has included prominent climate scientists tweeting that no Republicans are safe to have in Congress, popularizers like Neil deGrasse Tyson trolling Christians on Twitter on Christmas Day.

Scheufele warned againstDemocrats’ tendency to align science with other (probably very worthwhile) social causes, including the various yard signs that equate science to B.L.M., gender equality, immigration, etc. The tricky part is that most of these causes are seen as Democratic-leaning policy issues

Science is not that. It’s society’s best way of creating and curating knowledge, regardless of what that science will mean for politics, belief systems, or personal preferences.

For many on the left, Scheufele wrote,Science has become a signaling device for liberals to distinguish themselves from what they see as “anti-science” Republicans. That spells trouble

Science relies on the public perception that it creates knowledge objectively and in a politically neutral way. The moment we lose that aspect of trust, we just become one of the many institutions, including Congress, that have suffered from rapidly eroding levels of public trust.

I soon discovered that I had as much to learn from the counsel of the dead as I did from the advice and consent of the living. The reading of history damps down the impulse to slander the trend and tenor of the times, instills a sense of humor, lessens our fear of what might happen tomorrow.

y object was to learn, not preach, which prevented my induction into the national college of pundits but encouraged my reading of history.

On the opening of a book or the looking into a manuscript, I listen for the sound of a voice in the first-person singular, and from authors whom I read more than once I learn to value the weight of words and to delight in their meter and cadence—in Gibbon’s polyphonic counterpoint and Guedalla’s command of the subjunctive, in Mailer’s hyperbole and Dillard’s similes, in Twain’s invectives and burlesques with which he set the torch of his ferocious wit to the hospitality tents of the world’s “colossal humbug.”

On listening to President Barack Obama preach the doctrine of freedom-loving military invasion to the cadets at West Point, I’m reminded of the speeches that sent the Athenian army to its destruction in Sicily in 415 bc, and I don’t have to wait for dispatches from Afghanistan to suspect that the shooting script for the Pax Americana is a tale told by an idiot.

The common store of our shared history is what Goethe had in mind when he said that the inability to “draw on three thousand years is living hand to mouth.”

It isn’t with symbolic icons that men make their immortality. They do so with what they’ve learned on their travels across the frontiers of the millennia, salvaging from the wreck of time what they find to be useful or beautiful or true.

What preserves the voices of the great authors from one century to the next is not the recording device (the clay tablet, the scroll, the codex, the book, the computer, the iPad) but the force of imagination and the power of expression. It is the strength of the words themselves, not their product placement, that invites the play of mind and induces a change of heart.

How do we know what we think we know? Why is it that the more information we collect the less likely we are to grasp what it means? Possibly because a montage is not a narrative, the ear is not the eye, a pattern recognition is not a figure or a form of speech.

The surfeit of new and newer news comes so quickly to hand that within the wind tunnels of the “innovative delivery strategies” the data blow away and shred. The time is always now, and what gets lost is all thought of what happened yesterday, last week, three months or three years ago. Unlike moths and fruit flies, human beings bereft of memory, even as poor a memory as Montaigne’s or my own, tend to become disoriented and confused.

I know no other way out of what is both the maze of the eternal present and the prison of the self except with a string of words.

Teams of neurologists at six research centers asked 241 unresponsive patients to spend several minutes at a time doing complex cognitive tasks, such as imagining themselves playing tennis. Twenty-five percent of them responded with the same patterns of brain activity seen in healthy people, suggesting that they were able to think and were at least somewhat aware.

the study shows that up to 100,000 patients in the United States alone might have some level of consciousness despite their devastating injuries.

The results should lead to more sophisticated exams of people with so-called disorders of consciousness, and to more research into how these patients might communicate with the outside world, he said: “It’s not OK to know this and to do nothing.”

A patient who doesn’t respond at all might be diagnosed as being in a vegetative state. A patient who produces only fleeting responses might be diagnosed as minimally conscious.

Six groups of experts, including Dr. Owen’s and Dr. Schiff’s teams, began collaborating on a survey in 2008. To accelerate it, they figured out how to record brain activity in patients with an electrode-covered cap. It’s much easier to use electrodes to test patients at their bedside than to wheel them into a brain scanner.

The researchers tested 241 patients who did not respond to commands during a traditional exam. They also had healthy volunteers perform the same tasks. The researchers then handed the data over to a team of statisticians at the Icahn School of Medicine at Mount Sinai. The team performed the analysis without knowing which results came from which research group.

Their analysis revealed that 60 patients showed signs of awareness on the functional M.R.I. scans, electrode recordings, or both. The results were published in The New England Journal of Medicine.

Dr. Schiff said that the results may be biased by the fact that he and his colleagues examined the patients eight months on average after their injuries. The people who managed to survive that long might be more resilient than the ones who died sooner. And that resilience might have made them more likely to remain aware.

On the other hand, Dr. Schiff argued, the tests were so demanding that some patients with some awareness probably did not score positive results. “We’re likely to be missing people,”

“This is, without a doubt, the largest study that’s ever been done” of these patients, he said. “It’s done by the best people at the best places, so we’re not going to be seeing a better one coming down the pike in a long, long time.”

On Wednesday, another team of researchers reported that a patient paralyzed by amyotrophic lateral sclerosis, or Lou Gehrig’s disease, was able to communicate through a brain implant after just 30 minutes of training

“We have tens of thousands of people like that,” he said. “We should do something about it.”

It is terribly difficult to make people care about things they don’t already have an interest in—especially if you haven’t nurtured the trust necessary to lead your audience.

As a result, news organizations frequently take cues from what they perceive people will be interested in. This often means covering people who already attract a lot of attention, under the guise of newsworthiness.

We are already seeing the first wave of "who won and who lost" sorts of stories pitting various governors' responses against each other in horse-race fashion, as if these were early polls for the 2024 presidential election.

Then reality stepped in. A surge of summer cases forced the imposition of some restrictions on Floridians, like local mask mandates imposed by mayors in some cities in South Florida.

Now DeSantis is claiming again to be a master of pandemic control, as Florida's beach-tourism-restaurant industry is said to be doing well. Never mind that the state's seven-day infection rate of 143.9 per 100,000 population places it 12th highest of the 50 states.

For example, as of March 22, over the last seven days, Florida has had the most Covid-19 cases in the country, according to data from the US Centers for Disease Control and Prevention (CDC), the 12th highest per capita case-rate, the fourth highest number of deaths, and the 17th highest death rate.

Once celebrated for his pandemic management, he is now getting poor marks on managing. He has not strutted or had roundtables of fan-doctors to sing his praise. But the fact is California's recent numbers are much better than those of Florida, coming in at about 47th in the country with a case-rate 46.8 per 100,000, according to the CDC's data, and fewer deaths as well.

Florida is ignoring the death toll and instead pushing the upbeat metrics the governor would like America to pay attention to: jobs are up! and schools are open! DeSantis stood up to the Covid-19 threat like John Wayne would have done!

Rather than wallow in reality, she chose to celebrate an active economy and the joys of hunting season (note: the South Dakota new-infection rate is climbing the charts once again and sits at 105 per 100,000 South Dakotans ).

These rate-the-governors perspectives ignore a basic fact: it is no time for trophies.

Worse, this obeisance to economic and social factors as measure of success creates a series of disturbing false equivalencies as they compare deaths against the economy.

Measuring Covid-19 management on anything other than the number of human lives lost is not only disgraceful, it will also almost certainly lead us to make all the wrong decisions once again and usher in yet another Covid-19 resurgence in the US.

It marked the first time in the 231-year history of the United States that a president has been impeached twice in his term.

Another presidential run in 2024 would be a very real possibility.Instead, Trump is on the ropes. He's been silenced from social media, including his beloved Twitter account. Even if he is not prohibited from running for office by a Senate conviction, his power and influence within the Republican Party has been dented.

For five years, Trump has been proving critics and prognosticators who penned his political epitaph wrong. He's survived scandals and controversies that would take down most other politicians.This time, at long last, could be different.

"The European relationship has changed and will now be shrouded in skepticism,"

Trump's outward aggression affected all aspects of European life, be it trade, defense or even the emotional shared ideas and cultural ties.

All those things suddenly seem debased and of less value."

"When they did take big stances on things like China or Iran, they chose not to involve anyone, leaving Europeans scrambling for a response,"

But he might have to accept that America's role in these relationships has changed."

This has led to lots of countries having to think more seriously about their future with a less assertive US,"

"In some respects, it was a good thing Trump forced us to think more about diplomatic initiatives, NATO and withdrawal of US troops,"

A view many European officials share is that no matter how friendly Biden is, Trump happened once -- and could happen again.

In 2024, Ivanka Trump, Donald Trump Jr., Mike Pompeo, or any other of his allies could conceivably pick up the torch and win an election.

"We cannot afford to be naive. If you look at the number of votes that Trump got, he wields an influence on American voters.

This anti-global, 'America First' undercurrent in American politics is still very much alive and we have to hedge our bets,"

For the US, it's unclear whether being downgraded as a diplomatic force is something that its citizens, who've lived through four introspective years of "America First," will even care about.

Regardless, the Trump era has left Europeans with little choice but to wait and see how much of a priority Biden places on reclaiming America's place on the world stage.

The four RS-25s can generate 1.6 million lbs (7 Meganewtons) of thrust

This will make it 15% more powerful than the giant Saturn V rocket that sent astronauts to the Moon in the 1960s and 70s.

“The struggle to defend objective truth against people who consciously choose to deny or distort it has become a fight to defend our society, and democracy itself.”

Jonathan Swift, it’s worth noting that he was not an optimist about “truth.”

By the time a lie is refuted, he wrote, “it is too late; the jest is over, and the tale has had its effect: like a man, who has thought of a good repartee, when the discourse is changed, or the company parted; or like a physician, who has found out an infallible medicine, after the patient is dead.'“

“Considering that natural disposition in many men to lie, and in multitudes to believe,” he wrote in 1710, “I have been perplexed what to do with that maxim so frequent in every body's mouth; that truth will at last prevail.

A recent Washington Post tally found that nearly 300 Republicans running for congressional and state offices are election deniers. That means, as a FiveThirtyEight analysis found, 60 percent of Americans will have at least one election denier on their ballot next week.

In a new USA Today/Suffolk University poll, 63 percent of Republicans say they worry “the election results could be manipulated.”

From the New York Times: When asked, six Trump-backed Republican nominees for governor and the Senate in midterm battlegrounds would not commit to accepting this year’s election results.

The big mistake people have made is in assuming this could blow up only in an extensive struggle in 2024 and perhaps involving Donald Trump. What seems entirely unanticipated, yet is extremely predictable, is that smaller skirmishes could break out all over the country this year.

Democrats have got themselves in a situation where the head of their party holds the most popular position on guns and crime—and yet they’re getting crushed on the issue because they’ve let GOP campaign ads, the right wing media ecosystem, and assorted progressive big city prosecutors shape the narrative on the issue rather than doing so themselves.

What’s left, across all platforms, is fragmented. News and punditry are everywhere online, but audiences are siloed; podcasts are more popular than ever, and millions of younger people online have turned to influencers and creators on Instagram and especially TikTok as trusted sources of news.

Social media, especially Twitter, has sometimes been an incredible news-gathering tool; it has also been terrible and inefficient, a game of do your own research that involves batting away bullshit and parsing half truths, hyperbole, outright lies, and invaluable context from experts on the fly. Social media’s greatest strength is thus its original sin: These sites are excellent at making you feel connected and informed, frequently at the expense of actually being informed.

At the center of these pleas for a Twitter alternative is a feeling that a fundamental promise has been broken. In exchange for our time, our data, and even our well-being, we uploaded our most important conversations onto platforms designed for viral advertising—all under the implicit understanding that social media could provide an unparalleled window to the world.

What comes next is impossible to anticipate, but it’s worth considering the possibility that the centrality of social media as we’ve known it for the past 15 years has come to an end—that this particular window to the world is being slammed shut.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

People believe that memory should be effortless, but their expectations for how much they should remember are totally out of whack with how much they’re capable of remembering.1

What is the most common misconception about memory?

Another misconception is that memory is supposed to be an archive of the past. We expect that we should be able to replay the past like a movie in our heads.

we don’t replay the past as it happened; we do it through a lens of interpretation and imagination.

How much are we capable of remembering, from both an episodic2 2 Episodic memory is the term for the memory of life experiences. and a semantic3 3 Semantic memory is the term for the memory of facts and knowledge about the world. standpoint?

I would argue that we’re all everyday-memory experts, because we have this exceptional semantic memory, which is the scaffold for episodic memory.

If what we’re remembering, or the emotional tenor of what we’re remembering, is dictated by how we’re thinking in a present moment, what can we really say about the truth of a memory?

But if memories are malleable, what are the implications for how we understand our “true” selves?

your question gets to a major purpose of memory, which is to give us an illusion of stability in a world that is always changing. Because if we look for memories, we’ll reshape them into our beliefs of what’s happening right now. We’ll be biased in terms of how we sample the past. We have these illusions of stability, but we are always changing

And depending on what memories we draw upon, those life narratives can change.

we have this illusion that much of the world is cause and effect. But the reason, in my opinion, that we have that illusion is that our brain is constantly trying to find the patterns

One thing that makes the human brain so sophisticated is that we have a longer timeline in which we can integrate information than many other species. That gives us the ability to say: “Hey, I’m walking up and giving money to the cashier at the cafe. The barista is going to hand me a cup of coffee in about a minute or two.”

There is this illusion that we know exactly what’s going to happen, but the fact is we don’t. Memory can overdo it: Somebody lied to us once, so they are a liar; somebody shoplifted once, they are a thief.

If people have a vivid memory of something that sticks out, that will overshadow all their knowledge about the way things work. So there’s kind of an illus

I know it sounds squirmy to say, “Well, I can’t answer the question of how much we remember,” but I don’t want readers to walk away thinking memory is all made up.

I think of memory more like a painting than a photograph. There’s often photorealistic aspects of a painting, but there’s also interpretation. As a painter evolves, they could revisit the same subject over and over and paint differently based on who they are now. We’re capable of remembering things in extraordinary detail, but we infuse meaning into what we remember. We’re designed to extract meaning from the past, and that meaning should have truth in it. But it also has knowledge and imagination and, sometimes, wisdom.

memory, often, is educated guesses by the brain about what’s important. So what’s important? Things that are scary, things that get your desire going, things that are surprising. Maybe you were attracted to this person, and your eyes dilated, your pulse went up. Maybe you were working on something in this high state of excitement, and your dopamine was up.

It could be any of those things, but they’re all important in some way, because if you’re a brain, you want to take what’s surprising, you want to take what’s motivationally important for survival, what’s new.

On the more intentional side, are there things that we might be able to do in the moment to make events last in our memories? In some sense, it’s about being mindful. If we want to form a new memory, focus on aspects of the experience you want to take with you.

If you’re with your kid, you’re at a park, focus on the parts of it that are great, not the parts that are kind of annoying. Then you want to focus on the sights, the sounds, the smells, because those will give you rich detail later on

Another part of it, too, is that we kill ourselves by inducing distractions in our world. We have alerts on our phones. We check email habitually.

When we go on trips, I take candid shots. These are the things that bring you back to moments. If you capture the feelings and the sights and the sounds that bring you to the moment, as opposed to the facts of what happened, that is a huge part of getting the best of memory.

this goes back to the question of whether the factual truth of a memory matters to how we interpret it. I think it matters to have some truth, but then again, many of the truths we cling to depend on our own perspective.

There’s a great experiment on this. These researchers had people read this story about a house.8 8 The study was “Recall of Previously Unrecallable Information Following a Shift in Perspective,” by Richard C. Anderson and James W. Pichert. One group of subjects is told, I want you to read this story from the perspective of a prospective home buyer. When they remember it, they remember all the features of the house that are described in the thing. Another group is told, I want you to remember this from the perspective of a burglar. Those people tend to remember the valuables in the house and things that you would want to take. But what was interesting was then they switched the groups around. All of a sudden, people could pull up a number of details that they didn’t pull up before. It was always there, but they just didn’t approach it from that mind-set. So we do have a lot of information that we can get if we change our perspective, and this ability to change our perspective is exceptionally important for being accurate. It’s exceptionally important for being able to grow and modify our beliefs

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

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

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

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

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

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

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

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

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

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

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