For Chat-Based AI, We Are All Once Again Tech Companies' Guinea Pigs - WSJ - 0 views

  • The companies touting new chat-based artificial-intelligence systems are running a massive experiment—and we are the test subjects.
  • In this experiment, Microsoft, MSFT -2.18% OpenAI and others are rolling out on the internet an alien intelligence that no one really understands, which has been granted the ability to influence our assessment of what’s true in the world. 
  • Companies have been cautious in the past about unleashing this technology on the world. In 2019, OpenAI decided not to release an earlier version of the underlying model that powers both ChatGPT and the new Bing because the company’s leaders deemed it too dangerous to do so, they said at the time.
  • ...26 more annotations...
  • Microsoft leaders felt “enormous urgency” for it to be the company to bring this technology to market, because others around the world are working on similar tech but might not have the resources or inclination to build it as responsibly, says Sarah Bird, a leader on Microsoft’s responsible AI team.
  • One common starting point for such models is what is essentially a download or “scrape” of most of the internet. In the past, these language models were used to try to understand text, but the new generation of them, part of the revolution in “generative” AI, uses those same models to create texts by trying to guess, one word at a time, the most likely word to come next in any given sequence.
  • Wide-scale testing gives Microsoft and OpenAI a big competitive edge by enabling them to gather huge amounts of data about how people actually use such chatbots. Both the prompts users input into their systems, and the results their AIs spit out, can then be fed back into a complicated system—which includes human content moderators paid by the companies—to improve it.
  • , being first to market with a chat-based AI gives these companies a huge initial lead over companies that have been slower to release their own chat-based AIs, such as Google.
  • rarely has an experiment like Microsoft and OpenAI’s been rolled out so quickly, and at such a broad scale.
  • Among those who build and study these kinds of AIs, Mr. Altman’s case for experimenting on the global public has inspired responses ranging from raised eyebrows to condemnation.
  • The fact that we’re all guinea pigs in this experiment doesn’t mean it shouldn’t be conducted, says Nathan Lambert, a research scientist at the AI startup Huggingface.
  • “I would kind of be happier with Microsoft doing this experiment than a startup, because Microsoft will at least address these issues when the press cycle gets really bad,” says Dr. Lambert. “I think there are going to be a lot of harms from this kind of AI, and it’s better people know they are coming,” he adds.
  • Others, particularly those who study and advocate for the concept of “ethical AI” or “responsible AI,” argue that the global experiment Microsoft and OpenAI are conducting is downright dangerous
  • Celeste Kidd, a professor of psychology at University of California, Berkeley, studies how people acquire knowledge
  • Her research has shown that people learning about new things have a narrow window in which they form a lasting opinion. Seeing misinformation during this critical initial period of exposure to a new concept—such as the kind of misinformation that chat-based AIs can confidently dispense—can do lasting harm, she says.
  • Dr. Kidd likens OpenAI’s experimentation with AI to exposing the public to possibly dangerous chemicals. “Imagine you put something carcinogenic in the drinking water and you were like, ‘We’ll see if it’s carcinogenic.’ After, you can’t take it back—people have cancer now,”
  • Part of the challenge with AI chatbots is that they can sometimes simply make things up. Numerous examples of this tendency have been documented by users of both ChatGPT and OpenA
  • These models also tend to be riddled with biases that may not be immediately apparent to users. For example, they can express opinions gleaned from the internet as if they were verified facts
  • When millions are exposed to these biases across billions of interactions, this AI has the potential to refashion humanity’s views, at a global scale, says Dr. Kidd.
  • OpenAI has talked publicly about the problems with these systems, and how it is trying to address them. In a recent blog post, the company said that in the future, users might be able to select AIs whose “values” align with their own.
  • “We believe that AI should be a useful tool for individual people, and thus customizable by each user up to limits defined by society,” the post said.
  • Eliminating made-up information and bias from chat-based search engines is impossible given the current state of the technology, says Mark Riedl, a professor at Georgia Institute of Technology who studies artificial intelligence
  • He believes the release of these technologies to the public by Microsoft and OpenAI is premature. “We are putting out products that are still being actively researched at this moment,” he adds. 
  • in other areas of human endeavor—from new drugs and new modes of transportation to advertising and broadcast media—we have standards for what can and cannot be unleashed on the public. No such standards exist for AI, says Dr. Riedl.
  • To modify these AIs so that they produce outputs that humans find both useful and not-offensive, engineers often use a process called “reinforcement learning through human feedback.
  • that’s a fancy way of saying that humans provide input to the raw AI algorithm, often by simply saying which of its potential responses to a query are better—and also which are not acceptable at all.
  • Microsoft’s and OpenAI’s globe-spanning experiments on millions of people are yielding a fire hose of data for both companies. User-entered prompts and the AI-generated results are fed back through a network of paid human AI trainers to further fine-tune the models,
  • Huggingface’s Dr. Lambert says that any company, including his own, that doesn’t have this river of real-world usage data helping it improve its AI is at a huge disadvantage
  • In chatbots, in some autonomous-driving systems, in the unaccountable AIs that decide what we see on social media, and now, in the latest applications of AI, again and again we are the guinea pigs on which tech companies are testing new technology.
  • It may be the case that there is no other way to roll out this latest iteration of AI—which is already showing promise in some areas—at scale. But we should always be asking, at times like these: At what price?

Functional medicine: Is it the future of healthcare or just another wellness trend? - I... - 0 views

  • Functional Medicine is the alternative medicine Bill Clinton credits with giving him his life back after his 2004 quadruple heart by-pass surgery. Its ideology is embraced by Oprah and regularly features on Gwyneth Paltrow's Goop.
  • Developed in 1990 by Dr Jeffrey Bland, who in 1991 set up the Institute of Functional Medicine with his wife Susan, today the field is spearheaded by US best-selling author Dr Mark Hyman, adviser to the Clintons and co-director of the controversial Cleveland Clinic for Functional Medicine.
  • "Functional Medicine is not about a test or a supplement or a particular protocol," he adds. "It's really a new paradigm of disease and how it arises and how to restore health. Within it there are many approaches that are effective, it's not exclusive, it doesn't exclude traditional medications, it includes all modalities depending on what's right for that patient."
  • ...31 more annotations...
  • Functional Medicine isn't a protected title and a medical qualification isn't a prerequisite to practice. The result is an unregulated and disparate field, with medical doctors, nutritionists, naturopaths and homeopaths among the many practitioners.
  • Some other chronic illnesses the field claims to treat include heart disease, type 2 diabetes, irritable bowel syndrome, ulcerative colitis, depression, anxiety and arthritis
  • ll kinds of different reasons, some might have gluten issues, gut issues, others might have a deficiency causing neurological issues, MS is a symptom."
  • "There are components of Functional Medicine that absolutely lack an evidence base and there are practitioners of what they call Functional Medicine, they charge people for intravenous nutritional injections, they exaggerate claims, and that is professionally inappropriate, unethical and it lacks evidence.
  • On Dr Mark Hyman's view of MS he says, "there are a lot of terms put together there, all of which individually make a lot of sense, but put together in that way they do not.
  • "What does FM actually mean? It means nothing. It's a gift-gallop of words thrown together. It's criticised by advocates of evidence-based medicine because it's giving a veneer of scientific legitimacy to ideas that are considered pseudoscientific. For example, it'll take alternative medicine modalities like homeopathy and then call them 'bio-infusions' or something similar, rebranding it as something that works.
  • "It's a redundant name, real medicine is functional."
  • Next month the third annual Lifestyle and Functional Medical conference will take place in Salthill, Galway on November 3. Last year's event was attended by more than 500 people and featured a keynote address by honorary consultant cardiologist Dr Aseem Malhotra, author of bestselling The Pioppi Diet (which was named one of the top five worst celebrity diets to avoid in 2018 by the British Dietetic Foundation).
  • Dr David Robert Grimes is physicist and visiting fellow of Oxford and QUB. His research into cancer focuses on modelling tumour metabolism and radiation interactions. For Dr Grimes, the lack of definition, or "double-speak" as he puts it, in FM is troubling.
  • As well as the cost of appointments, FM practitioners commonly charge extra for tests. An omega finger prick test is around €100. A vitamin D test can cost upwards of €60, full thyroid panel more than €150 and a gut function test €400. Prices vary between practitioners.
  • "If I, as a GP, engaged in some of these behaviours I would be struck off." Specifically? "If I was recommending treatments that lacked an evidence base, or if I was promoting diagnostic tests which are expensive and lack an evidence base.
  • GPs engage every year in ongoing continuous professional development, I spend my evenings and my weekends outside of working hours attending educational events, small-group learning, large-group learning, engaging in research. This is an accusation that was levelled at the profession 30 years ago and then it was correct, but the profession has caught up…
  • "Obviously promoting wellness and healthy diet is very welcome but going beyond that and stating that certain aspects of 'functional medicine' can lead to reduced inflammation or prevent cancer, we have to be very careful about those claims.
  • Often the outcome of such tests are seemingly 'benign' prescriptions of vitamins or cleanses. However, dietitian Orla Walsh stresses that even these can have potentially harmful effects, especially on "vulnerable" patients, if not prescribed judiciously.
  • FM has five basic principles. 1. We are all genetically and biochemically unique so it treats the individual, not the disease. 2. It's science-based. 3. The body is intelligent and has the capacity for self-regulation. 4. The body has the ability to heal and prevent nearly all the diseases of ageing. 5. Health is not just the absence of disease, but a state of immense vitality.
  • She began her Functional Medicine career while training as a medical doctor and now travels the world working with high-profile clients. Dr McHale charges €425 for an initial consultation and €175 for follow-up appointments. Straightforward lab tests are €250 to €750, for complex cases testing fees can be up to €2,000.
  • "The term [Functional Medicine] tends to be bandied around quite a bit. Other things people say, such as 'functional nutritionist', can be misleading as a term. Many people are Functional Medicine practitioners but don't have any real medical background at all... I think regulation is always probably the best way forward."
  • "There's an awful lot to it in terms of biochemistry and physiology," she says. "You do need to have a very solid and well ingrained bio-chemistry background. A solely clinical background doesn't equip you with the knowledge to read a test.
  • "Evidence-base is the cornerstone of medicine and that has to be maintained. It becomes problematic in this area because you are looking at personalised medicine and that can be very difficult to evidence-base."
  • GP Christine Ritter travelled from England to attend the Galway conference last year with a view to integrating Functional Medicine into her practice.
  • "It was very motivating," she says. "Where it wasn't perhaps as strong was to find the evidence. The Functional Medicine people would say, 'we've done this study and this trial and we've used this supplement that was successful', but they can't show massive research data which might make it difficult to bring it into the mainstream.
  • "I also know the rigorous standard of trials we have in medicine they're not usually that great either, it's often driven by who's behind the trial and who's paying for it.
  • "Every approach that empowers patient to work on their destiny [is beneficial], but you'd have to be mindful that you're not missing any serious conditions."
  • Dr Hyman is working to grow the evidence-base for Functional Medicine worldwide. "The future is looking very bright," he says. "At the Cleveland Centre we're establishing a research base, building educational platforms, fellowships, residency programmes, rotations. We're advancing the field that's spreading across the world. We're seeing in China the development of a programme of Functional Medicine, South Africa, the UK, in London the Cleveland Clinic will hopefully have a Functional Medicine centre."
  • For Dr Mark Murphy regulation is a moot point as it can only apply once the field meets the standards of evidence-based medicine.
  • "Despite well intentioned calls for regulation, complementary and alternative medical therapies cannot be regulated," he says. "Only therapies that possess an evidence-base can enter our standard regulatory processes, including the Irish Medical Council, the Health Products Regulatory Authority and Irish advertising standards. In situations where complementary and alternative therapies develop an evidence base, they are no longer 'complementary and alternative', but in effect they become part of mainstream 'Medicine'.
  • l What are the principles?
  • "There's a huge variation between therapists, some are brilliant and some are okay, and some are ludicrous snake oil salesmen."
  • He is so concerned that patients' health and wealth are being put at risk by alternative therapies that earlier this year he joined Fine Gael TD Kate O'Connell and the Irish Cancer Society in introducing draft legislation earlier this year making it illegal to sell unproven treatments to cancer patients. Violators face jail and heavy fines.
  • Dr Grimes says criticism of variations in the standards of traditional medical research can be fair, however due to the weight of research it is ultimately self-correcting. He adds, "The reality is that good trials are transparent, independent and pre-registered.
  • "My involvement in shaping the Bill came from seeing first-hand the exploitation of patients and their families. Most patients undergoing treatment will take some alternative modalities in conjunction but a significant portion are talked out of their conventional medicine and seduced by false promises

Jonathan Haidt on the 'National Crisis' of Gen Z - WSJ - 0 views

  • he has in mind the younger cohort, Generation Z, usually defined as those born between 1997 and 2012. “When you look at Americans born after 1995,” Mr. Haidt says, “what you find is that they have extraordinarily high rates of anxiety, depression, self-harm, suicide and fragility.” There has “never been a generation this depressed, anxious and fragile.”
  • He attributes this to the combination of social media and a culture that emphasizes victimhood
  • Social media is Mr. Haidt’s present obsession. He’s working on two books that address its harmful impact on American society: “Kids in Space: Why Teen Mental Health Is Collapsing” and “Life After Babel: Adapting to a World We Can No Longer Share.
  • ...26 more annotations...
  • What happened in 2012, when the oldest Gen-Z babies were in their middle teens? That was the year Facebook acquired Instagram and young people flocked to the latter site. It was also “the beginning of the selfie era.”
  • Mr. Haidt’s research, confirmed by that of others, shows that depression rates started to rise “all of a sudden” around 2013, “especially for teen girls,” but “it’s only Gen Z, not the older generations.” If you’d stopped collecting data in 2011, he says, you’d see little change from previous years. “By 2015 it’s an epidemic.” (His data are available in an open-source document.)
  • Mr. Haidt imagines “literally launching our children into outer space” and letting their bodies grow there: “They would come out deformed and broken. Their limbs wouldn’t be right. You can’t physically grow up in outer space. Human bodies can’t do that.” Yet “we basically do that to them socially. We launched them into outer space around the year 2012,” he says, “and then we expect that they will grow up normally without having normal human experiences.”
  • He calls this phenomenon “compare and despair” and says: “It seems social because you’re communicating with people. But it’s performative. You don’t actually get social relationships. You get weak, fake social links.”
  • That meant the first social-media generation was one of “weakened kids” who “hadn’t practiced the skills of adulthood in a low-stakes environment” with other children. They were deprived of “the normal toughening, the normal strengthening, the normal anti-fragility.
  • Now, their childhood “is largely just through the phone. They no longer even hang out together.” Teenagers even drive less than earlier generations did.
  • Mr. Haidt especially worries about girls. By 2020 more than 25% of female teenagers had “a major depression.” The comparable number for boys was just under 9%.
  • The comparable numbers for millennials at the same age registered at half the Gen-Z rate: about 13% for girls and 5% for boys. “Kids are on their devices all the time,”
  • Most girls, by contrast, are drawn to “visual platforms,” Instagram and TikTok in particular. “Those are about display and performance. You post your perfect life, and then you flip through the photos of other girls who have a more perfect life, and you feel depressed.
  • Mr. Haidt says he has no antipathy toward the young, and he calls millennials “amazing.”
  • “Social media is incompatible with liberal democracy because it has moved conversation, and interaction, into the center of the Colosseum. We’re not there to talk to each other. We’re there to perform” before spectators who “want blood.”
  • To illustrate his point about Gen Z, Mr. Haidt challenges people to name young people today who are “really changing the world, who are doing big things that have an impact beyond their closed ecosystem.”
  • He can think of only two, neither of them American: Greta Thunberg, 19, the Swedish climate militant, and Malala Yousafzai, 25, the Pakistani advocate for female education
  • I’m predicting that they will be less effective, less impactful, than previous generations.” Why? “You should always keep your eye on whether people are in ‘discover mode’ or ‘defend mode.’ ” In the former mode, you seize opportunities to be creative. In the latter, “you’re not creative, you’re not future-thinking, you’re focused on threats in the present.”
  • University students who matriculated starting in 2014 or so have arrived on campus in defend mode: “Here they are in the safest, most welcoming, most inclusive, most antiracist places on the planet, but many of them were acting like they were entering some sort of dystopian, threatening, immoral world.”
  • 56% of liberal women 18 to 29 responded affirmatively to the question: Has a doctor or other healthcare provider ever told you that you have a mental health condition? “Some of that,” Mr. Haidt says, “has to be just self-presentational,” meaning imagined.
  • This new ideology . . . valorizes victimhood. And if your sub-community motivates you to say you have an anxiety disorder, how is this going to affect you for the rest of your life?” He answers his own question: “You’re not going to take chances, you’re going to ask for accommodations, you’re going to play it safe, you’re not going to swing for the fences, you’re not going to start your own company.”
  • Whereas millennial women are doing well, “Gen-Z women, because they’re so anxious, are going to be less successful than Gen-Z men—and that’s saying a lot, because Gen-Z men are messed up, too.”
  • The problem, he says, is distinct to the U.S. and other English-speaking developed countries: “You don’t find it as much in Europe, and hardly at all in Asia.” Ideas that are “nurtured around American issues of race and gender spread instantly to the U.K. and Canada. But they don’t necessarily spread to France and Germany, China and Japan.”
  • something I hear from a lot of managers, that it’s very difficult to supervise their Gen-Z employees, that it’s very difficult to give them feedback.” That makes it hard for them to advance professionally by learning to do their jobs better.
  • “this could severely damage American capitalism.” When managers are “afraid to speak up honestly because they’ll be shamed on Twitter or Slack, then that organization becomes stupid.” Mr. Haidt says he’s “seen a lot of this, beginning in American universities in 2015. They all got stupid in the same way. They all implemented policies that backfire.”
  • Mr. Haidt, who describes himself as “a classical liberal like John Stuart Mill,” also laments the impact of social media on political discourse
  • Social media and selfies hit a generation that had led an overprotected childhood, in which the age at which children were allowed outside on their own by parents had risen from the norm of previous generations, 7 or 8, to between 10 and 12.
  • Is there a solution? “I’d raise the age of Internet adulthood to 16,” he says—“and enforce it.”
  • By contrast, “life went onto phone-based apps 10 years ago, and the protections we have for children are zero, absolutely zero.” The damage to Generation Z from social media “so vastly exceeds the damage from Covid that we’re going to have to act.”
  • Gen Z, he says, “is not in denial. They recognize that this app-based life is really bad for them.” He reports that they wish they had childhoods more like those of their parents, in which they could play outside and have adventur

A Leading Memory Researcher Explains How to Make Precious Moments Last - The New York T... - 0 views

  • Our memories form the bedrock of who we are. Those recollections, in turn, are built on one very simple assumption: This happened. But things are not quite so simple
  • “We update our memories through the act of remembering,” says Charan Ranganath, a professor of psychology and neuroscience at the University of California, Davis, and the author of the illuminating new book “Why We Remember.” “So it creates all these weird biases and infiltrates our decision making. It affects our sense of who we are.
  • Rather than being photo-accurate repositories of past experience, Ranganath argues, our memories function more like active interpreters, working to help us navigate the present and future. The implication is that who we are, and the memories we draw on to determine that, are far less fixed than you might think. “Our identities,” Ranganath says, “are built on shifting sand.”
  • ...24 more annotations...
  • 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.
  • 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.
  • 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
  • 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
  • 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
