An Adaptation From 'Flash Boys: A Wall Street Revolt,' by Michael Lewis - NYTimes.com - 0 views

  • Ryan was making hundreds of thousands of dollars a year building systems to make stock-market trades faster. He was struck, over and over again, by how little those he helped understood the technology they were using
  • Ryan described what he witnessed inside the exchanges: The frantic competition for nanoseconds, clients’ trying to get their machines closer to the servers within the exchanges, the tens of millions being spent by high-frequency traders for tiny increments of speed. The U.S. stock market was now a class system of haves and have-nots, only what was had was not money but speed (which led to money).
  • A salesman at RBC who marketed Thor recalls one big investor calling to say, “You know, I thought I knew what I did for a living, but apparently not, because I had no idea this was going on.”

  • Eventually Brad Katsuyama came to realize that the most sophisticated investors didn’t know what was going on in their own market. Not the big mutual funds, Fidelity and Vanguard. Not the big money-management firms like T. Rowe Price and Capital Group. Not even the most sophisticated hedge funds.
  • The deep problem with the system was a kind of moral inertia. So long as it served the narrow self-interests of everyone inside it, no one on the inside would ever seek to change it, no matter how corrupt or sinister it became
  • Technology had collided with Wall Street in a peculiar way. It had been used to increase efficiency. But it had also been used to introduce a peculiar sort of market inefficiency. Taking advantage of loopholes in some well-meaning regulation introduced in the mid-2000s, some large amount of what Wall Street had been doing with technology was simply so someone inside the financial markets would know something that the outside world did not. The same system that once gave us subprime-mortgage collateralized debt obligations no investor could possibly truly understand now gave us stock-market trades involving fractions of a penny that occurred at unsafe speeds using order types that no investor could possibly truly understand.
  • The trouble with the stock market — with all of the public and private exchanges — was that they were fantastically gameable, and had been gamed: first by clever guys in small shops, and then by prop traders who moved inside the big Wall Street banks. That was the problem, Puz thought. From the point of view of the most sophisticated traders, the stock market wasn’t a mechanism for channeling capital to productive enterprise but a puzzle to be solved.
  • As they worked through the order types, the Puzzle Masters created a taxonomy of predatory behavior in the stock market. Broadly speaking, it appeared as if there were three activities that led to a vast amount of grotesquely unfair trading. The first they called electronic front-running — seeing an investor trying to do something in one place and racing ahead of him to the next (what had happened to Katsuyama when he traded at RBC). The second they called rebate arbitrage — using the new complexity to game the seizing of whatever legal kickbacks, called rebates within the industry, the exchange offered without actually providing the liquidity that the rebate was presumably meant to entice. The third, and probably by far the most widespread, they called slow-market arbitrage. This occurred when a high-frequency trader was able to see the price of a stock change on one exchange and pick off orders sitting on other exchanges before those exchanges were able to react. This happened all day, every day, and very likely generated more billions of dollars a year than the other strategies combined.
  • IEX had made its point: That to function properly, a financial market didn’t need to be rigged in someone’s favor. It didn’t need payment for order flow and co-location and all sorts of unfair advantages possessed by a small handful of traders. All it needed was for investors to take responsibility for understanding it, and then to seize its controls. “The backbone of the market,” Katsuyama says, “is investors coming together to trade.”
  • If an investor as large as T. Rowe Price, which acted on behalf of millions of investors, had trouble obtaining the information it needed to determine if its brokers had acted in their interest, what chance did the little guy have?
  • The stock market really was rigged. Katsuyama often wondered how enterprising politicians and plaintiffs’ lawyers and state attorneys general would respond to that realization. (This March, the New York attorney general, Eric Schneiderman, announced a new investigation of the stock exchanges and the dark pools, and their relationships with high-frequency traders.

I Had My DNA Picture Taken, With Varying Results - NYTimes.com - 0 views

  • Scientists have identified about 10 million SNPs within our three billion nucleotides. But an entire genome sequencing — looking at all three billion nucleotides — would cost around $3,000; the tests I took examined fewer than a million SNPs.
  • “Imagine if you took a book and you only looked at the first letter of every other page,” said Dr. Robert Klitzman, a bioethicist and professor of clinical psychiatry at Columbia. (I am a graduate student there in his Master of Bioethics program.) “You’re missing 99.9 percent of the letters that make the genome. The information is going to be limited.”
  • the major issue, experts say, is that the causes of most common diseases remain unknown. Genes account for just 5 to 20 percent of the whole picture.

  • “Your results are not the least bit surprising,” he told me. “Anything short of sequencing is going to be short on accuracy — and even then, there’s almost no comprehensive data sets to compare to.”
  • “Even if they are accurately looking at 5 percent of the attributable risk, they’ve ignored the vast majority of the other risk factors — the dark matter for genetics — because we as a scientific community haven’t yet identified those risk factors,”
  • There are only 23 diseases that start in adulthood, can be treated, and for which highly predictive tests exist. All are rare, with hereditary breast cancer the most common. “A small percentage of people who get tested will get useful information,” Dr. Klitzman said. “But for most people, the results are not clinically useful, and they may be misleading or confusing.”
  • To be sure, my tests did provide some beneficial information. They all agreed that I lack markers associated with an increased risk of breast cancer and Alzheimer’s. That said, they were testing for only a small fraction of the genetic risks for these diseases, not for rare genetic variants that confer much of the risk. I could still develop those diseases, of course, but I don’t have reason to pursue aggressive screenings as I age.
  • He added: “If you want to spend money wisely to protect your health and you have a few hundred dollars, buy a scale, stand on it, and act accordingly.”

'Nothing on this page is real': How lies become truth in online America - The Washingto... - 0 views

  • “Share if you’re outraged!” his posts often read, and thousands of people on Facebook had clicked “like” and then “share,” most of whom did not recognize his posts as satire. Instead, Blair’s page had become one of the most popular on Facebook among Trump-supporting conservatives over 55.
  • “Nothing on this page is real,” read one of the 14 disclaimers on Blair’s site, and yet in the America of 2018 his stories had become real, reinforcing people’s biases, spreading onto Macedonian and Russian fake news sites, amassing an audience of as many 6 million visitors each month who thought his posts were factual
  • “No matter how racist, how bigoted, how offensive, how obviously fake we get, people keep coming back,” Blair once wrote, on his own personal Facebook page. “Where is the edge? Is there ever a point where people realize they’re being fed garbage and decide to return to reality?”

  • Chapian didn’t believe everything she read online, but she was also distrustful of mainstream fact-checkers and reported news. It sometimes felt to her like real facts had become indiscernible — that the truth was often somewhere in between. What she trusted most was her own ability to think critically and discern the truth, and increasingly her instincts aligned with the online community where she spent most of her time.
  • Her number of likes and shares on Facebook increased each year until she was sometimes awakening to check her news feed in the middle of the night, liking and commenting on dozens of posts each day. She felt as if she was being let in on a series of dark revelations about the United States, and it was her responsibility to see and to share them.

At the Existentialist Café: Freedom, Being, and Apricot Cocktails with Jean-P... - 0 views

  • The phenomenologists’ leading thinker, Edmund Husserl, provided a rallying cry, ‘To the things themselves!’ It meant: don’t waste time on the interpretations that accrue upon things, and especially don’t waste time wondering whether the things are real. Just look at this that’s presenting itself to you, whatever this may be, and describe it as precisely as possible.
  • You might think you have defined me by some label, but you are wrong, for I am always a work in progress. I create myself constantly through action, and this is so fundamental to my human condition that, for Sartre, it is the human condition, from the moment of first consciousness to the moment when death wipes it out. I am my own freedom: no more, no less.
  • Sartre wrote like a novelist — not surprisingly, since he was one. In his novels, short stories and plays as well as in his philosophical treatises, he wrote about the physical sensations of the world and the structures and moods of human life. Above all, he wrote about one big subject: what it meant to be free. Freedom, for him, lay at the heart of all human experience, and this set humans apart from all other kinds of object.
  • ...97 more annotations...
  • Sartre listened to his problem and said simply, ‘You are free, therefore choose — that is to say, invent.’ No signs are vouchsafed in this world, he said. None of the old authorities can relieve you of the burden of freedom. You can weigh up moral or practical considerations as carefully as you like, but ultimately you must take the plunge and do something, and it’s up to you what that something is.
  • Even if the situation is unbearable — perhaps you are facing execution, or sitting in a Gestapo prison, or about to fall off a cliff — you are still free to decide what to make of it in mind and deed. Starting from where you are now, you choose. And in choosing, you also choose who you will be.
  • The war had made people realise that they and their fellow humans were capable of departing entirely from civilised norms; no wonder the idea of a fixed human nature seemed questionable.
  • If this sounds difficult and unnerving, it’s because it is. Sartre does not deny that the need to keep making decisions brings constant anxiety. He heightens this anxiety by pointing out that what you do really matters. You should make your choices as though you were choosing on behalf of the whole of humanity, taking the entire burden of responsibility for how the human race behaves. If you avoid this responsibility by fooling yourself that you are the victim of circumstance or of someone else’s bad advice, you are failing to meet the demands of human life and choosing a fake existence, cut off from your own ‘authenticity’.
  • Along with the terrifying side of this comes a great promise: Sartre’s existentialism implies that it is possible to be authentic and free, as long as you keep up the effort.
  • almost all agreed that it was, as an article in Les nouvelles littéraires phrased it, a ‘sickening mixture of philosophic pretentiousness, equivocal dreams, physiological technicalities, morbid tastes and hesitant eroticism … an introspective embryo that one would take distinct pleasure in crushing’.
  • he offered a philosophy designed for a species that had just scared the hell out of itself, but that finally felt ready to grow up and take responsibility.
  • In this rebellious world, just as with the Parisian bohemians and Dadaists in earlier generations, everything that was dangerous and provocative was good, and everything that was nice or bourgeois was bad.
  • Such interweaving of ideas and life had a long pedigree, although the existentialists gave it a new twist. Stoic and Epicurean thinkers in the classical world had practised philosophy as a means of living well, rather than of seeking knowledge or wisdom for their own sake. By reflecting on life’s vagaries in philosophical ways, they believed they could become more resilient, more able to rise above circumstances, and better equipped to manage grief, fear, anger, disappointment or anxiety.
  • In the tradition they passed on, philosophy is neither a pure intellectual pursuit nor a collection of cheap self-help tricks, but a discipline for flourishing and living a fully human, responsible life.
  • For Kierkegaard, Descartes had things back to front. In his own view, human existence comes first: it is the starting point for everything we do, not the result of a logical deduction. My existence is active: I live it and choose it, and this precedes any statement I can make about myself.
  • Studying our own moral genealogy cannot help us to escape or transcend ourselves. But it can enable us to see our illusions more clearly and lead a more vital, assertive existence.
  • What was needed, he felt, was not high moral or theological ideals, but a deeply critical form of cultural history or ‘genealogy’ that would uncover the reasons why we humans are as we are, and how we came to be that way. For him, all philosophy could even be redefined as a form of psychology, or history.
  • For those oppressed on grounds of race or class, or for those fighting against colonialism, existentialism offered a change of perspective — literally, as Sartre proposed that all situations be judged according to how they appeared in the eyes of those most oppressed, or those whose suffering was greatest.
  • She observed that we need not expect moral philosophers to ‘live by’ their ideas in a simplistic way, as if they were following a set of rules. But we can expect them to show how their ideas are lived in. We should be able to look in through the windows of a philosophy, as it were, and see how people occupy it, how they move about and how they conduct themselves.
  • the existentialists inhabited their historical and personal world, as they inhabited their ideas. This notion of ‘inhabited philosophy’ is one I’ve borrowed from the English philosopher and novelist Iris Murdoch, who wrote the first full-length book on Sartre and was an early adopter of existentialism
  • What is existentialism anyway?
  • An existentialist who is also phenomenological provides no easy rules for dealing with this condition, but instead concentrates on describing lived experience as it presents itself. — By describing experience well, he or she hopes to understand this existence and awaken us to ways of living more authentic lives.
  • Existentialists concern themselves with individual, concrete human existence. — They consider human existence different from the kind of being other things have. Other entities are what they are, but as a human I am whatever I choose to make of myself at every moment. I am free — — and therefore I’m responsible for everything I do, a dizzying fact which causes — an anxiety inseparable from human existence itself.
  • On the other hand, I am only free within situations, which can include factors in my own biology and psychology as well as physical, historical and social variables of the world into which I have been thrown. — Despite the limitations, I always want more: I am passionately involved in personal projects of all kinds. — Human existence is thus ambiguous: at once boxed in by borders and yet transcendent and exhilarating. —
  • The first part of this is straightforward: a phenomenologist’s job is to describe. This is the activity that Husserl kept reminding his students to do. It meant stripping away distractions, habits, clichés of thought, presumptions and received ideas, in order to return our attention to what he called the ‘things themselves’. We must fix our beady gaze on them and capture them exactly as they appear, rather than as we think they are supposed to be.
  • Husserl therefore says that, to phenomenologically describe a cup of coffee, I should set aside both the abstract suppositions and any intrusive emotional associations. Then I can concentrate on the dark, fragrant, rich phenomenon in front of me now. This ‘setting aside’ or ‘bracketing out’ of speculative add-ons Husserl called epoché — a term borrowed from the ancient Sceptics,
  • The point about rigour is crucial; it brings us back to the first half of the command to describe phenomena. A phenomenologist cannot get away with listening to a piece of music and saying, ‘How lovely!’ He or she must ask: is it plaintive? is it dignified? is it colossal and sublime? The point is to keep coming back to the ‘things themselves’ — phenomena stripped of their conceptual baggage — so as to bail out weak or extraneous material and get to the heart of the experience.
  • Husserlian ‘bracketing out’ or epoché allows the phenomenologist to temporarily ignore the question ‘But is it real?’, in order to ask how a person experiences his or her world. Phenomenology gives a formal mode of access to human experience. It lets philosophers talk about life more or less as non-philosophers do, while still being able to tell themselves they are being methodical and rigorous.
  • Besides claiming to transform the way we think about reality, phenomenologists promised to change how we think about ourselves. They believed that we should not try to find out what the human mind is, as if it were some kind of substance. Instead, we should consider what it does, and how it grasps its experiences.
  • For Brentano, this reaching towards objects is what our minds do all the time. Our thoughts are invariably of or about something, he wrote: in love, something is loved, in hatred, something is hated, in judgement, something is affirmed or denied. Even when I imagine an object that isn’t there, my mental structure is still one of ‘about-ness’ or ‘of-ness’.
  • Except in deepest sleep, my mind is always engaged in this aboutness: it has ‘intentionality’. Having taken the germ of this from Brentano, Husserl made it central to his whole philosophy.
  • Husserl saw in the idea of intentionality a way to sidestep two great unsolved puzzles of philosophical history: the question of what objects ‘really’ are, and the question of what the mind ‘really’ is. By doing the epoché and bracketing out all consideration of reality from both topics, one is freed to concentrate on the relationship in the middle. One can apply one’s descriptive energies to the endless dance of intentionality that takes place in our lives: the whirl of our minds as they seize their intended phenomena one after the other and whisk them around the floor,
  • Understood in this way, the mind hardly is anything at all: it is its aboutness. This makes the human mind (and possibly some animal minds) different from any other naturally occurring entity. Nothing else can be as thoroughly about or of things as the mind is:
  • Some Eastern meditation techniques aim to still this scurrying creature, but the extreme difficulty of this shows how unnatural it is to be mentally inert. Left to itself, the mind reaches out in all directions as long as it is awake — and even carries on doing it in the dreaming phase of its sleep.
  • a mind that is experiencing nothing, imagining nothing, or speculating about nothing can hardly be said to be a mind at all.
  • Three simple ideas — description, phenomenon, intentionality — provided enough inspiration to keep roomfuls of Husserlian assistants busy in Freiburg for decades. With all of human existence awaiting their attention, how could they ever run out of things to do?
  • For Sartre, this gives the mind an immense freedom. If we are nothing but what we think about, then no predefined ‘inner nature’ can hold us back. We are protean.
  • way of this interpretation. Real, not real; inside, outside; what difference did it make? Reflecting on this, Husserl began turning his phenomenology into a branch of ‘idealism’ — the philosophical tradition which denied external reality and defined everything as a kind of private hallucination.
  • For Sartre, if we try to shut ourselves up inside our own minds, ‘in a nice warm room with the shutters closed’, we cease to exist. We have no cosy home: being out on the dusty road is the very definition of what we are.
  • One might think that, if Heidegger had anything worth saying, he could have communicated it in ordinary language. The fact is that he does not want to be ordinary, and he may not even want to communicate in the usual sense. He wants to make the familiar obscure, and to vex us. George Steiner thought that Heidegger’s purpose was less to be understood than to be experienced through a ‘felt strangeness’.
  • He takes Dasein in its most ordinary moments, then talks about it in the most innovative way he can. For Heidegger, Dasein’s everyday Being is right here: it is Being-in-the-world, or In-der-Welt-sein. The main feature of Dasein’s everyday Being-in-the-world right here is that it is usually busy doing something.
  • Thus, for Heidegger, all Being-in-the-world is also a ‘Being-with’ or Mitsein. We cohabit with others in a ‘with-world’, or Mitwelt. The old philosophical problem of how we prove the existence of other minds has now vanished. Dasein swims in the with-world long before it wonders about other minds.
  • Sometimes the best-educated people were those least inclined to take the Nazis seriously, dismissing them as too absurd to last. Karl Jaspers was one of those who made this mistake, as he later recalled, and Beauvoir observed similar dismissive attitudes among the French students in Berlin.
  • In any case, most of those who disagreed with Hitler’s ideology soon learned to keep their view to themselves. If a Nazi parade passed on the street, they would either slip out of view or give the obligatory salute like everyone else, telling themselves that the gesture meant nothing if they did not believe in it. As the psychologist Bruno Bettelheim later wrote of this period, few people will risk their life for such a small thing as raising an arm — yet that is how one’s powers of resistance are eroded away, and eventually one’s responsibility and integrity go with them.
  • for Arendt, if you do not respond adequately when the times demand it, you show a lack of imagination and attention that is as dangerous as deliberately committing an abuse. It amounts to disobeying the one command she had absorbed from Heidegger in those Marburg days: Think!
  • ‘Everything takes place under a kind of anaesthesia. Objectively dreadful events produce a thin, puny emotional response. Murders are committed like schoolboy pranks. Humiliation and moral decay are accepted like minor incidents.’ Haffner thought modernity itself was partly to blame: people had become yoked to their habits and to mass media, forgetting to stop and think, or to disrupt their routines long enough to question what was going on.
  • Heidegger’s former lover and student Hannah Arendt would argue, in her 1951 study The Origins of Totalitarianism, that totalitarian movements thrived at least partly because of this fragmentation in modern lives, which made people more vulnerable to being swept away by demagogues. Elsewhere, she coined the phrase ‘the banality of evil’ to describe the most extreme failures of personal moral awareness.
  • His communicative ideal fed into a whole theory of history: he traced all civilisation to an ‘Axial Period’ in the fifth century BC, during which philosophy and culture exploded simultaneously in Europe, the Middle East and Asia, as though a great bubble of minds had erupted from the earth’s surface. ‘True philosophy needs communion to come into existence,’ he wrote, and added, ‘Uncommunicativeness in a philosopher is virtually a criterion of the untruth of his thinking.’
  • The idea of being called to authenticity became a major theme in later existentialism, the call being interpreted as saying something like ‘Be yourself!’, as opposed to being phony. For Heidegger, the call is more fundamental than that. It is a call to take up a self that you didn’t know you had: to wake up to your Being. Moreover, it is a call to action. It requires you to do something: to take a decision of some sort.
  • Being and Time contained at least one big idea that should have been of use in resisting totalitarianism. Dasein, Heidegger wrote there, tends to fall under the sway of something called das Man or ‘the they’ — an impersonal entity that robs us of the freedom to think for ourselves. To live authentically requires resisting or outwitting this influence, but this is not easy because das Man is so nebulous. Man in German does not mean ‘man’ as in English (that’s der Mann), but a neutral abstraction, something like ‘one’ in the English phrase ‘one doesn’t do that’,
  • for Heidegger, das Man is me. It is everywhere and nowhere; it is nothing definite, but each of us is it. As with Being, it is so ubiquitous that it is difficult to see. If I am not careful, however, das Man takes over the important decisions that should be my own. It drains away my responsibility or ‘answerability’. As Arendt might put it, we slip into banality, failing to think.
  • Jaspers focused on what he called Grenzsituationen — border situations, or limit situations. These are the moments when one finds oneself constrained or boxed in by what is happening, but at the same time pushed by these events towards the limits or outer edge of normal experience. For example, you might have to make a life-or-death choice, or something might remind you suddenly of your mortality,
  • Jaspers’ interest in border situations probably had much to do with his own early confrontation with mortality. From childhood, he had suffered from a heart condition so severe that he always expected to die at any moment. He also had emphysema, which forced him to speak slowly, taking long pauses to catch his breath. Both illnesses meant that he had to budget his energies with care in order to get his work done without endangering his life.
  • If I am to resist das Man, I must become answerable to the call of my ‘voice of conscience’. This call does not come from God, as a traditional Christian definition of the voice of conscience might suppose. It comes from a truly existentialist source: my own authentic self. Alas, this voice is one I do not recognise and may not hear, because it is not the voice of my habitual ‘they-self’. It is an alien or uncanny version of my usual voice. I am familiar with my they-self, but not with my unalienated voice — so, in a weird twist, my real voice is the one that sounds strangest to me.
  • Marcel developed a strongly theological branch of existentialism. His faith distanced him from both Sartre and Heidegger, but he shared a sense of how history makes demands on individuals. In his essay ‘On the Ontological Mystery’, written in 1932 and published in the fateful year of 1933, Marcel wrote of the human tendency to become stuck in habits, received ideas, and a narrow-minded attachment to possessions and familiar scenes. Instead, he urged his readers to develop a capacity for remaining ‘available’ to situations as they arise. Similar ideas of disponibilité or availability had been explored by other writers,
  • Marcel made it his central existential imperative. He was aware of how rare and difficult it was. Most people fall into what he calls ‘crispation’: a tensed, encrusted shape in life — ‘as though each one of us secreted a kind of shell which gradually hardened and imprisoned him’.
  • Bettelheim later observed that, under Nazism, only a few people realised at once that life could not continue unaltered: these were the ones who got away quickly. Bettelheim himself was not among them. Caught in Austria when Hitler annexed it, he was sent first to Dachau and then to Buchenwald, but was then released in a mass amnesty to celebrate Hitler’s birthday in 1939 — an extraordinary reprieve, after which he left at once for America.
  • we are used to reading philosophy as offering a universal message for all times and places — or at least as aiming to do so. But Heidegger disliked the notion of universal truths or universal humanity, which he considered a fantasy. For him, Dasein is not defined by shared faculties of reason and understanding, as the Enlightenment philosophers thought. Still less is it defined by any kind of transcendent eternal soul, as in religious tradition. We do not exist on a higher, eternal plane at all. Dasein’s Being is local: it has a historical situation, and is constituted in time and place.
  • For Marcel, learning to stay open to reality in this way is the philosopher’s prime job. Everyone can do it, but the philosopher is the one who is called on above all to stay awake, so as to be the first to sound the alarm if something seems wrong.
  • Second, it also means understanding that we are historical beings, and grasping the demands our particular historical situation is making on us. In what Heidegger calls ‘anticipatory resoluteness’, Dasein discovers ‘that its uttermost possibility lies in giving itself up’. At that moment, through Being-towards-death and resoluteness in facing up to one’s time, one is freed from the they-self and attains one’s true, authentic self.
  • If we are temporal beings by our very nature, then authentic existence means accepting, first, that we are finite and mortal. We will die: this all-important realisation is what Heidegger calls authentic ‘Being-towards-Death’, and it is fundamental to his philosophy.
  • Hannah Arendt, instead, left early on: she had the benefit of a powerful warning. Just after the Nazi takeover, in spring 1933, she had been arrested while researching materials on anti-Semitism for the German Zionist Organisation at Berlin’s Prussian State Library. Her apartment was searched; both she and her mother were locked up briefly, then released. They fled, without stopping to arrange travel documents. They crossed to Czechoslovakia (then still safe) by a method that sounds almost too fabulous to be true: a sympathetic German family on the border had a house with its front door in Germany and its back door in Czechoslovakia. The family would invite people for dinner, then let them leave through the back door at night.
  • As Sartre argued in his 1943 review of The Stranger, basic phenomenological principles show that experience comes to us already charged with significance. A piano sonata is a melancholy evocation of longing. If I watch a soccer match, I see it as a soccer match, not as a meaningless scene in which a number of people run around taking turns to apply their lower limbs to a spherical object. If the latter is what I’m seeing, then I am not watching some more essential, truer version of soccer; I am failing to watch it properly as soccer at all.
  • Much as they liked Camus personally, neither Sartre nor Beauvoir accepted his vision of absurdity. For them, life is not absurd, even when viewed on a cosmic scale, and nothing can be gained by saying it is. Life for them is full of real meaning, although that meaning emerges differently for each of us.
  • For Sartre, we show bad faith whenever we portray ourselves as passive creations of our race, class, job, history, nation, family, heredity, childhood influences, events, or even hidden drives in our subconscious which we claim are out of our control. It is not that such factors are unimportant: class and race, in particular, he acknowledged as powerful forces in people’s lives, and Simone de Beauvoir would soon add gender to that list.
  • Sartre takes his argument to an extreme point by asserting that even war, imprisonment or the prospect of imminent death cannot take away my existential freedom. They form part of my ‘situation’, and this may be an extreme and intolerable situation, but it still provides only a context for whatever I choose to do next. If I am about to die, I can decide how to face that death. Sartre here resurrects the ancient Stoic idea that I may not choose what happens to me, but I can choose what to make of it, spiritually speaking.
  • But the Stoics cultivated indifference in the face of terrible events, whereas Sartre thought we should remain passionately, even furiously engaged with what happens to us and with what we can achieve. We should not expect freedom to be anything less than fiendishly difficult.
  • Freedom does not mean entirely unconstrained movement, and it certainly does not mean acting randomly. We often mistake the very things that enable us to be free — context, meaning, facticity, situation, a general direction in our lives — for things that define us and take away our freedom. It is only with all of these that we can be free in a real sense.
  • Nor did he mean that privileged groups have the right to pontificate to the poor and downtrodden about the need to ‘take responsibility’ for themselves. That would be a grotesque misreading of Sartre’s point, since his sympathy in any encounter always lay with the more oppressed side. But for each of us — for me — to be in good faith means not making excuses for myself.
  • Camus’ novel gives us a deliberately understated vision of heroism and decisive action compared to those of Sartre and Beauvoir. One can only do so much. It can look like defeatism, but it shows a more realistic perception of what it takes to actually accomplish difficult tasks like liberating one’s country.
  • Camus just kept returning to his core principle: no torture, no killing — at least not with state approval. Beauvoir and Sartre believed they were taking a more subtle and more realistic view. If asked why a couple of innocuous philosophers had suddenly become so harsh, they would have said it was because the war had changed them in profound ways. It had shown them that one’s duties to humanity could be more complicated than they seemed. ‘The war really divided my life in two,’ Sartre said later.
  • Poets and artists ‘let things be’, but they also let things come out and show themselves. They help to ease things into ‘unconcealment’ (Unverborgenheit), which is Heidegger’s rendition of the Greek term alētheia, usually translated as ‘truth’. This is a deeper kind of truth than the mere correspondence of a statement to reality, as when we say ‘The cat is on the mat’ and point to a mat with a cat on it. Long before we can do this, both cat and mat must ‘stand forth out of concealedness’. They must un-hide themselves.
  • Heidegger does not use the word ‘consciousness’ here because — as with his earlier work — he is trying to make us think in a radically different way about ourselves. We are not to think of the mind as an empty cavern, or as a container filled with representations of things. We are not even supposed to think of it as firing off arrows of intentional ‘aboutness’, as in the earlier phenomenology of Brentano. Instead, Heidegger draws us into the depths of his Schwarzwald, and asks us to imagine a gap with sunlight filtering in. We remain in the forest, but we provide a relatively open spot where other beings can bask for a moment. If we did not do this, everything would remain in the thickets, hidden even to itself.
  • The astronomer Carl Sagan began his 1980 television series Cosmos by saying that human beings, though made of the same stuff as the stars, are conscious and are therefore ‘a way for the cosmos to know itself’. Merleau-Ponty similarly quoted his favourite painter Cézanne as saying, ‘The landscape thinks itself in me, and I am its consciousness.’ This is something like what Heidegger thinks humanity contributes to the earth. We are not made of spiritual nothingness; we are part of Being, but we also bring something unique with us. It is not much: a little open space, perhaps with a path and a bench like the one the young Heidegger used to sit on to do his homework. But through us, the miracle occurs.
  • Beauty aside, Heidegger’s late writing can also be troubling, with its increasingly mystical notion of what it is to be human. If one speaks of a human being mainly as an open space or a clearing, or a means of ‘letting beings be’ and dwelling poetically on the earth, then one doesn’t seem to be talking about any recognisable person. The old Dasein has become less human than ever. It is now a forestry feature.
  • Even today, Jaspers, the dedicated communicator, is far less widely read than Heidegger, who has influenced architects, social theorists, critics, psychologists, artists, film-makers, environmental activists, and innumerable students and enthusiasts — including the later deconstructionist and post-structuralist schools, which took their starting point from his late thinking. Having spent the late 1940s as an outsider and then been rehabilitated, Heidegger became the overwhelming presence in university philosophy all over the European continent from then on.
  • As Levinas reflected on this experience, it helped to lead him to a philosophy that was essentially ethical, rather than ontological like Heidegger’s. He developed his ideas from the work of Jewish theologian Martin Buber, whose I and Thou in 1923 had distinguished between my relationship with an impersonal ‘it’ or ‘them’, and the direct personal encounter I have with a ‘you’. Levinas took it further: when I encounter you, we normally meet face-to-face, and it is through your face that you, as another person, can make ethical demands on me. This is very different from Heidegger’s Mitsein or Being-with, which suggests a group of people standing alongside one another, shoulder to shoulder as if in solidarity — perhaps as a unified nation or Volk.
  • For Levinas, we literally face each other, one individual at a time, and that relationship becomes one of communication and moral expectation. We do not merge; we respond to one another. Instead of being co-opted into playing some role in my personal drama of authenticity, you look me in the eyes — and you remain Other. You remain you.
  • This relationship is more fundamental than the self, more fundamental than consciousness, more fundamental even than Being — and it brings an unavoidable ethical obligation. Ever since Husserl, phenomenologists and existentialists had being trying to stretch the definition of existence to incorporate our social lives and relationships. Levinas did more: he turned philosophy around entirely so that these relationships were the foundation of our existence, not an extension of it.
  • Her last work, The Need for Roots, argues, among other things, that none of us has rights, but each one of us has a near-infinite degree of duty and obligation to the other. Whatever the underlying cause of her death — and anorexia nervosa seems to have been involved — no one could deny that she lived out her philosophy with total commitment. Of all the lives touched on in this book, hers is surely the most profound and challenging application of Iris Murdoch’s notion that a philosophy can be ‘inhabited’.
  • Other thinkers took radical ethical turns during the war years. The most extreme was Simone Weil, who actually tried to live by the principle of putting other people’s ethical demands first. Having returned to France after her travels through Germany in 1932, she had worked in a factory so as to experience the degrading nature of such work for herself. When France fell in 1940, her family fled to Marseilles (against her protests), and later to the US and to Britain. Even in exile, Weil made extraordinary sacrifices. If there were people in the world who could not sleep in a bed, she would not do so either, so she slept on the floor.
  • The mystery tradition had roots in Kierkegaard’s ‘leap of faith’. It owed much to the other great nineteenth-century mystic of the impossible, Dostoevsky, and to older theological notions. But it also grew from the protracted trauma that was the first half of the twentieth century. Since 1914, and especially since 1939, people in Europe and elsewhere had come to the realisation that we cannot fully know or trust ourselves; that we have no excuses or explanations for what we do — and yet that we must ground our existence and relationships on something firm, because otherwise we cannot survive.
  • One striking link between these radical ethical thinkers, all on the fringes of our main story, is that they had religious faith. They also granted a special role to the notion of ‘mystery’ — that which cannot be known, calculated or understood, especially when it concerns our relationships with each other. Heidegger was different from them, since he rejected the religion he grew up with and had no real interest in ethics — probably as a consequence of his having no real interest in the human.
  • Meanwhile, the Christian existentialist Gabriel Marcel was also still arguing, as he had since the 1930s, that ethics trumps everything else in philosophy and that our duty to each other is so great as to play the role of a transcendent ‘mystery’. He too had been led to this position partly by a wartime experience: during the First World War he had worked for the Red Cross’ Information Service, with the unenviable job of answering relatives’ inquiries about missing soldiers. Whenever news came, he passed it on, and usually it was not good. As Marcel later said, this task permanently inoculated him against warmongering rhetoric of any kind, and it made him aware of the power of what is unknown in our lives.
  • As the play’s much-quoted and frequently misunderstood final line has it: ‘Hell is other people.’ Sartre later explained that he did not mean to say that other people were hellish in general. He meant that after death we become frozen in their view, unable any longer to fend off their interpretation. In life, we can still do something to manage the impression we make; in death, this freedom goes and we are left entombed in other’s people’s memories and perceptions.
  • We have to do two near-impossible things at once: understand ourselves as limited by circumstances, and yet continue to pursue our projects as though we are truly in control. In Beauvoir’s view, existentialism is the philosophy that best enables us to do this, because it concerns itself so deeply with both freedom and contingency. It acknowledges the radical and terrifying scope of our freedom in life, but also the concrete influences that other philosophies tend to ignore: history, the body, social relationships and the environment.
  • The aspects of our existence that limit us, Merleau-Ponty says, are the very same ones that bind us to the world and give us scope for action and perception. They make us what we are. Sartre acknowledged the need for this trade-off, but he found it more painful to accept. Everything in him longed to be free of bonds, of impediments and limitations
  • Of course we have to learn this skill of interpreting and anticipating the world, and this happens in early childhood, which is why Merleau-Ponty thought child psychology was essential to philosophy. This is an extraordinary insight. Apart from Rousseau, very few philosophers before him had taken childhood seriously; most wrote as though all human experience were that of a fully conscious, rational, verbal adult who has been dropped into this world from the sky — perhaps by a stork.
  • For Merleau-Ponty, we cannot understand our experience if we don’t think of ourselves in part as overgrown babies. We fall for optical illusions because we once learned to see the world in terms of shapes, objects and things relevant to our own interests. Our first perceptions came to us in tandem with our first active experiments in observing the world and reaching out to explore it, and are still linked with those experiences.
  • Another factor in all of this, for Merleau-Ponty, is our social existence: we cannot thrive without others, or not for long, and we need this especially in early life. This makes solipsistic speculation about the reality of others ridiculous; we could never engage in such speculation if we hadn’t already been formed by them.
  • As Descartes could have said (but didn’t), ‘I think, therefore other people exist.’ We grow up with people playing with us, pointing things out, talking, listening, and getting us used to reading emotions and movements; this is how we become capable, reflective, smoothly integrated beings.
  • In general, Merleau-Ponty thinks human experience only makes sense if we abandon philosophy’s time-honoured habit of starting with a solitary, capsule-like, immobile adult self, isolated from its body and world, which must then be connected up again — adding each element around it as though adding clothing to a doll. Instead, for him, we slide from the womb to the birth canal to an equally close and total immersion in the world. That immersion continues as long as we live, although we may also cultivate the art of partially withdrawing from time to time when we want to think or daydream.
  • When he looks for his own metaphor to describe how he sees consciousness, he comes up with a beautiful one: consciousness, he suggests, is like a ‘fold’ in the world, as though someone had crumpled a piece of cloth to make a little nest or hollow. It stays for a while, before eventually being unfolded and smoothed away. There is something seductive, even erotic, in this idea of my conscious self as an improvised pouch in the cloth of the world. I still have my privacy — my withdrawing room. But I am part of the world’s fabric, and I remain formed out of it for as long as I am here.
  • By the time of these works, Merleau-Ponty is taking his desire to describe experience to the outer limits of what language can convey. Just as with the late Husserl or Heidegger, or Sartre in his Flaubert book, we see a philosopher venturing so far from shore that we can barely follow. Emmanuel Levinas would head out to the fringes too, eventually becoming incomprehensible to all but his most patient initiates.
  • Sartre once remarked — speaking of a disagreement they had about Husserl in 1941 — that ‘we discovered, astounded, that our conflicts had, at times, stemmed from our childhood, or went back to the elementary differences of our two organisms’. Merleau-Ponty also said in an interview that Sartre’s work seemed strange to him, not because of philosophical differences, but because of a certain ‘register of feeling’, especially in Nausea, that he could not share. Their difference was one of temperament and of the whole way the world presented itself to them.
  • The two also differed in their purpose. When Sartre writes about the body or other aspects of experience, he generally does it in order to make a different point. He expertly evokes the grace of his café waiter, gliding between the tables, bending at an angle just so, steering the drink-laden tray through the air on the tips of his fingers — but he does it all in order to illustrate his ideas about bad faith. When Merleau-Ponty writes about skilled and graceful movement, the movement itself is his point. This is the thing he wants to understand.
  • We can never move definitively from ignorance to certainty, for the thread of the inquiry will constantly lead us back to ignorance again. This is the most attractive description of philosophy I’ve ever read, and the best argument for why it is worth doing, even (or especially) when it takes us no distance at all from our starting point.
  • By prioritising perception, the body, social life and childhood development, Merleau-Ponty gathered up philosophy’s far-flung outsider subjects and brought them in to occupy the centre of his thought.
  • In his inaugural lecture at the Collège de France on 15 January 1953, published as In Praise of Philosophy, he said that philosophers should concern themselves above all with whatever is ambiguous in our experience. At the same time, they should think clearly about these ambiguities, using reason and science. Thus, he said, ‘The philosopher is marked by the distinguishing trait that he possesses inseparably the taste for evidence and the feeling for ambiguity.’ A constant movement is required between these two
  • As Sartre wrote in response to Hiroshima, humanity had now gained the power to wipe itself out, and must decide every single day that it wanted to live. Camus also wrote that humanity faced the task of choosing between collective suicide and a more intelligent use of its technology — ‘between hell and reason’. After 1945, there seemed little reason to trust in humanity’s ability to choose well.
  • Merleau-Ponty observed in a lecture of 1951 that, more than any previous century, the twentieth century had reminded people how ‘contingent’ their lives were — how at the mercy of historical events and other changes that they could not control. This feeling went on long after the war ended. After the A-bombs were dropped on Hiroshima and Nagasaki, many feared that a Third World War would not be long in coming, this time between the Soviet Union and the United States.

What Does Quantum Physics Actually Tell Us About the World? - The New York Times - 2 views

  • The physics of atoms and their ever-smaller constituents and cousins is, as Adam Becker reminds us more than once in his new book, “What Is Real?,” “the most successful theory in all of science.” Its predictions are stunningly accurate, and its power to grasp the unseen ultramicroscopic world has brought us modern marvels.
  • But there is a problem: Quantum theory is, in a profound way, weird. It defies our common-sense intuition about what things are and what they can do.
  • Indeed, Heisenberg said that quantum particles “are not as real; they form a world of potentialities or possibilities rather than one of things or facts.”
  • ...19 more annotations...
  • Before he died, Richard Feynman, who understood quantum theory as well as anyone, said, “I still get nervous with it...I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.” The problem is not with using the theory — making calculations, applying it to engineering tasks — but in understanding what it means. What does it tell us about the world?
  • From one point of view, quantum physics is just a set of formalisms, a useful tool kit. Want to make better lasers or transistors or television sets? The Schrödinger equation is your friend. The trouble starts only when you step back and ask whether the entities implied by the equation can really exist. Then you encounter problems that can be described in several familiar ways:
  • Wave-particle duality. Everything there is — all matter and energy, all known forces — behaves sometimes like waves, smooth and continuous, and sometimes like particles, rat-a-tat-tat. Electricity flows through wires, like a fluid, or flies through a vacuum as a volley of individual electrons. Can it be both things at once?
  • The uncertainty principle. Werner Heisenberg famously discovered that when you measure the position (let’s say) of an electron as precisely as you can, you find yourself more and more in the dark about its momentum. And vice versa. You can pin down one or the other but not both.
  • The measurement problem. Most of quantum mechanics deals with probabilities rather than certainties. A particle has a probability of appearing in a certain place. An unstable atom has a probability of decaying at a certain instant. But when a physicist goes into the laboratory and performs an experiment, there is a definite outcome. The act of measurement — observation, by someone or something — becomes an inextricable part of the theory
  • The strange implication is that the reality of the quantum world remains amorphous or indefinite until scientists start measuring
  • Other interpretations rely on “hidden variables” to account for quantities presumed to exist behind the curtain.
  • This is disturbing to philosophers as well as physicists. It led Einstein to say in 1952, “The theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.”
  • “Figuring out what quantum physics is saying about the world has been hard,” Becker says, and this understatement motivates his book, a thorough, illuminating exploration of the most consequential controversy raging in modern science.
  • In a way, the Copenhagen is an anti-interpretation. “It is wrong to think that the task of physics is to find out how nature is,” Bohr said. “Physics concerns what we can say about nature.”
  • Nothing is definite in Bohr’s quantum world until someone observes it. Physics can help us order experience but should not be expected to provide a complete picture of reality. The popular four-word summary of the Copenhagen interpretation is: “Shut up and calculate!”
  • Becker sides with the worriers. He leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories
  • He makes a convincing case that it’s wrong to imagine the Copenhagen interpretation as a single official or even coherent statement. It is, he suggests, a “strange assemblage of claims.
  • An American physicist, David Bohm, devised a radical alternative at midcentury, visualizing “pilot waves” that guide every particle, an attempt to eliminate the wave-particle duality.
  • Competing approaches to quantum foundations are called “interpretations,” and nowadays there are many. The first and still possibly foremost of these is the so-called Copenhagen interpretation.
  • Perhaps the most popular lately — certainly the most talked about — is the “many-worlds interpretation”: Every quantum event is a fork in the road, and one way to escape the difficulties is to imagine, mathematically speaking, that each fork creates a new universe
  • if you think the many-worlds idea is easily dismissed, plenty of physicists will beg to differ. They will tell you that it could explain, for example, why quantum computers (which admittedly don’t yet quite exist) could be so powerful: They would delegate the work to their alter egos in other universes.
  • When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human.
  • If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation...exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

The Science of Snobbery: How We're Duped Into Thinking Fancy Things Are Better - The At... - 0 views

  • Expert judges and amateurs alike claim to judge classical musicians based on sound. But Tsay’s research suggests that the original judges, despite their experience and expertise, judged the competition (which they heard and watched live) based on visual information, just as amateurs do.
  • just like with classical music, we do not appraise wine in the way that we expect. 
  • Priceonomics revisited this seemingly damning research: the lack of correlation between wine enjoyment and price in blind tastings, the oenology students tricked by red food dye into describing a white wine like a red, a distribution of medals at tastings equivalent to what one would expect from pure chance, the grand crus described like cheap wines and vice-versa when the bottles are switched.
  • ...26 more annotations...
  • Taste does not simply equal your taste buds. It draws on information from all our senses as well as context. As a result, food is susceptible to the same trickery as wine. Adding yellow food dye to vanilla pudding leads people to experience a lemony taste. Diners eating in the dark at a chic concept restaurant confuse veal for tuna. Branding, packaging, and price tags are equally important to enjoyment. Cheap fish is routinely passed off as its pricier cousins at seafood and sushi restaurants. 
  • Just like with wine and classical music, we often judge food based on very different criteria than what we claim. The result is that our perceptions are easily skewed in ways we don’t anticipate. 
  • What does it mean for wine that presentation so easily trumps the quality imbued by being grown on premium Napa land or years of fruitful aging? Is it comforting that the same phenomenon is found in food and classical music, or is it a strike against the authenticity of our enjoyment of them as well? How common must these manipulations be until we concede that the influence of the price tag of a bottle of wine or the visual appearance of a pianist is not a trick but actually part of the quality?
  • To answer these questions, we need to investigate the underlying mechanism that leads us to judge wine, food, and music by criteria other than what we claim to value. And that mechanism seems to be the quick, intuitive judgments our minds unconsciously make
  • this unknowability also makes it easy to be led astray when our intuition makes a mistake. We may often be able to count on the price tag or packaging of food and wine for accurate information about quality. But as we believe that we’re judging based on just the product, we fail to recognize when presentation manipulates our snap judgments.
  • Participants were just as effective when watching 6 second video clips and when comparing their ratings to ratings of teacher effectiveness as measured by actual student test performance. 
  • The power of intuitive first impressions has been demonstrated in a variety of other contexts. One experiment found that people predicted the outcome of political elections remarkably well based on silent 10 second video clips of debates - significantly outperforming political pundits and predictions made based on economic indicators.
  • In a real world case, a number of art experts successfully identified a 6th century Greek statue as a fraud. Although the statue had survived a 14 month investigation by a respected museum that included the probings of a geologist, they instantly recognized something was off. They just couldn’t explain how they knew.
  • Cases like this represent the canon behind the idea of the “adaptive unconscious,” a concept made famous by journalist Malcolm Gladwell in his book Blink. The basic idea is that we constantly, quickly, and unconsciously do the equivalent of judging a book by its cover. After all, a cover provides a lot of relevant information in a world in which we don’t have time to read every page.
  • Gladwell describes the adaptive unconscious as “a kind of giant computer that quickly and quietly processes a lot of the data we need in order to keep functioning as human beings.”
  • In a famous experiment, psychologist Nalini Ambady provided participants in an academic study with 30 second silent video clips of a college professor teaching a class and asked them to rate the effectiveness of the professor.
  • In follow up experiments, Chia-Jung Tsay found that those judging musicians’ auditions based on visual cues were not giving preference to attractive performers. Rather, they seemed to look for visual signs of relevant characteristics like passion, creativity, and uniqueness. Seeing signs of passion is valuable information. But in differentiating between elite performers, it gives an edge to someone who looks passionate over someone whose play is passionate
  • Outside of these more eccentric examples, it’s our reliance on quick judgments, and ignorance of their workings, that cause people to act on ugly, unconscious biases
  • It’s also why - from a business perspective - packaging and presentation is just as important as the good or service on offer. Why marketing is just as important as product. 
  • Gladwell ends Blink optimistically. By paying closer attention to our powers of rapid cognition, he argues, we can avoid its pitfalls and harness its powers. We can blindly audition musicians behind a screen, look at a piece of art devoid of other context, and pay particular attention to possible unconscious bias in our performance reports.
  • But Gladwell’s success in demonstrating how the many calculations our adaptive unconscious performs without our awareness undermines his hopeful message of consciously harnessing its power.
  • As a former world-class tennis player and coach of over 50 years, Braden is a perfect example of the ideas behind thin slicing. But if he can’t figure out what his unconscious is up to when he recognizes double faults, why should anyone else expect to be up to the task?
  • flawed judgment in fields like medicine and investing has more serious consequences. The fact that expertise is so tricky leads psychologist Daniel Kahneman to assert that most experts should seek the assistance of statistics and algorithms in making decisions.
  • In his book Thinking, Fast and Slow, he describes our two modes of thought: System 1, like the adaptive unconscious, is our “fast, instinctive, and emotional” intuition. System 2 is our “slower, more deliberative, and more logical” conscious thought. Kahneman believes that we often leave decisions up to System 1 and generally place far “too much confidence in human judgment” due to the pitfalls of our intuition described above.
  • Not every judgment will be made in a field that is stable and regular enough for an algorithm to help us make judgments or predictions. But in those cases, he notes, “Hundreds of studies have shown that wherever we have sufficient information to build a model, it will perform better than most people.”
  • Experts can avoid the pitfalls of intuition more easily than laypeople. But they need help too, especially as our collective confidence in expertise leads us to overconfidence in their judgments. 
  • This article has referred to the influence of price tags and context on products and experiences like wine and classical music concerts as tricks that skew our perception. But maybe we should consider them a real, actual part of the quality.
  • Losing ourselves in a universe of relativism, however, will lead us to miss out on anything new or unique. Take the example of the song “Hey Ya!” by Outkast. When the music industry heard it, they felt sure it would be a hit. When it premiered on the radio, however, listeners changed the channel. The song sounded too dissimilar from songs people liked, so they responded negatively. 
  • It took time for people to get familiar with the song and realize that they enjoyed it. Eventually “Hey Ya!” became the hit of the summer.
  • Many boorish people talking about the ethereal qualities of great wine probably can't even identify cork taint because their impressions are dominated by the price tag and the wine label. But the classic defense of wine - that you need to study it to appreciate it - is also vindicated. The open question - which is both editorial and empiric - is what it means for the industry that constant vigilance and substantial study is needed to dependably appreciate wine for the product quality alone. But the questions is relevant to the enjoyment of many other products and experiences that we enjoy in life.
  • Maybe the most important conclusion is to not only recognize the fallibility of our judgments and impressions, but to recognize when it matters, and when it doesn’t

Who Decides What's Racist? - Persuasion - 1 views

  • The implication of Hannah-Jones’s tweet and candidate Biden’s quip seems to be that you can have African ancestry, dark skin, textured hair, and perhaps even some “culturally black” traits regarding tastes in food, music, and ways of moving through the world. But unless you hold the “correct” political beliefs and values, you are not authentically black.
  • In a now-deleted tweet from May 22, 2020, Nikole Hannah-Jones, a Pulitzer Prize-winning reporter for The New York Times, opined, “There is a difference between being politically black and being racially black.”
  • Shelly Eversley’s The Real Negro suggests that in the latter half of the 20th century, the criteria of what constitutes “authentic” black experience moved from perceptible outward signs, like the fact of being restricted to segregated public spaces and speaking in a “black” dialect, to psychological, interior signs. In this new understanding, Eversley writes, “the ‘truth’ about race is felt, not performed, not seen.”
  • ...26 more annotations...
  • This insight goes a long way to explaining the current fetishization of experience, especially if it is (redundantly) “lived.” Black people from all walks of life find themselves deferred to by non-blacks
  • black people certainly don’t all “feel” or “experience” the same things. Nor do they all "experience" the same event in an identical way. Finally, even when their experiences are similar, they don’t all think about or interpret their experiences in the same way.
  • we must begin to attend in a serious way to heterodox black voices
  • This need is especially urgent given the ideological homogeneity of the “antiracist” outlook and efforts of elite institutions, including media, corporations, and an overwhelmingly progressive academia. For the arbiters of what it means to be black that dominate these institutions, there is a fairly narrowly prescribed “authentic” black narrative, black perspective, and black position on every issue that matters.
  • When we hear the demand to “listen to black voices,” what is usually meant is “listen to the right black voices.”
  • Many non-black people have heard a certain construction of “the black voice” so often that they are perplexed by black people who don’t fit the familiar model.
  • Similarly, many activists are not in fact “pro-black”: they are pro a rather specific conception of “blackness” that is not necessarily endorsed by all black people.
  • This is where our new website, Free Black Thought (FBT), seeks to intervene in the national conversation. FBT honors black individuals for their distinctive, diverse, and heterodox perspectives, and offers up for all to hear a polyphony, perhaps even a cacophony, of different and differing black voices.
  • The practical effects of the new antiracism are everywhere to be seen, but in few places more clearly than in our children’s schools
  • one might reasonably question what could be wrong with teaching children “antiracist” precepts. But the details here are full of devils.
  • To take an example that could affect millions of students, the state of California has adopted a statewide Ethnic Studies Model Curriculum (ESMC) that reflects “antiracist” ideas. The ESMC’s content inadvertently confirms that contemporary antiracism is often not so much an extension of the civil rights movement but in certain respects a tacit abandonment of its ideals.
  • It has thus been condemned as a “perversion of history” by Dr. Clarence Jones, MLK’s legal counsel, advisor, speechwriter, and Scholar in Residence at the Martin Luther King, Jr. Institute at Stanford University:
  • Essentialist thinking about race has also gained ground in some schools. For example, in one elite school, students “are pressured to conform their opinions to those broadly associated with their race and gender and to minimize or dismiss individual experiences that don’t match those assumptions.” These students report feeling that “they must never challenge any of the premises of [the school’s] ‘antiracist’ teachings.”
  • In contrast, the non-white students were taught that they were “folx (sic) who do not benefit from their social identities,” and “have little to no privilege and power.”
  • The children with “white” in their identity map were taught that they were part of the “dominant culture” which has been “created and maintained…to hold power and stay in power.” They were also taught that they had “privilege” and that “those with privilege have power over others.
  • Or consider the third-grade students at R.I. Meyerholz Elementary School in Cupertino, California
  • Or take New York City’s public school system, one of the largest educators of non-white children in America. In an effort to root out “implicit bias,” former Schools Chancellor Richard Carranza had his administrators trained in the dangers of “white supremacy culture.”
  • A slide from a training presentation listed “perfectionism,” “individualism,” “objectivity” and “worship of the written word” as white supremacist cultural traits to be “dismantled,”
  • Finally, some schools are adopting antiracist ideas of the sort espoused by Ibram X. Kendi, according to whom, if metrics such as tests and grades reveal disparities in achievement, the project of measuring achievement must itself be racist.
  • Parents are justifiably worried about such innovations. What black parent wants her child to hear that grading or math are “racist” as a substitute for objective assessment and real learning? What black parent wants her child told she shouldn’t worry about working hard, thinking objectively, or taking a deep interest in reading and writing because these things are not authentically black?
  • Clearly, our children’s prospects for success depend on the public being able to have an honest and free-ranging discussion about this new antiracism and its utilization in schools. Even if some black people have adopted its tenets, many more, perhaps most, hold complex perspectives that draw from a constellation of rather different ideologies.
  • So let’s listen to what some heterodox black people have to say about the new antiracism in our schools.
  • Coleman Hughes, a fellow at the Manhattan Institute, points to a self-defeating feature of Kendi-inspired grading and testing reforms: If we reject high academic standards for black children, they are unlikely to rise to “those same rejected standards” and racial disparity is unlikely to decrease
  • Chloé Valdary, the founder of Theory of Enchantment, worries that antiracism may “reinforce a shallow dogma of racial essentialism by describing black and white people in generalizing ways” and discourage “fellowship among peers of different races.”
  • We hope it’s obvious that the point we’re trying to make is not that everyone should accept uncritically everything these heterodox black thinkers say. Our point in composing this essay is that we all desperately need to hear what these thinkers say so we can have a genuine conversation
  • We promote no particular politics or agenda beyond a desire to offer a wide range of alternatives to the predictable fare emanating from elite mainstream outlets. At FBT, Marxists rub shoulders with laissez-faire libertarians. We have no desire to adjudicate who is “authentically black” or whom to prefer.

Prior to this administration, decisions were closely scrutinized for, at the very least, legality, along with the impact on diplomacy, general norms, and basic grammar. This kind of legal scrutiny and due diligence is also a kind of friction--one that we now see has a lot of benefits. 
  • The deep lesson here isn’t about Donald Trump. It’s about the collision between the digital world and the real world.
  • In the real world, marginal costs are not zero. And so friction is a desirable element in helping to get to the optimal state. You want people to pause before making decisions.
  • described friction this summer as: “anything that inhibits user action within a digital interface, particularly anything that requires an additional click or screen.” For much of my time in the technology sector, friction was almost always seen as the enemy, a force to be vanquished. A “frictionless” experience was generally held up as the ideal state, the optimal product state.
  • Trump was riding the ultimate frictionless optimized engagement Twitter experience: he rode it all the way to the presidency, and then he crashed the presidency into the ground.
  • From a metrics and user point of view, the abstract notion of the President himself tweeting was exactly what Twitter wanted in its original platonic ideal. Twitter has been built to incentivize someone like Trump to engage and post
  • The other day we talked a little bit about how fighting disinformation, extremism, and online cults is like fighting a virus: There is no “cure.” Instead, what you have to do is create enough friction that the rate of spread becomes slow.
  • Our challenge is that when human and digital design comes into conflict, the artificial constraints we impose should be on the digital world to become more in service to us. Instead, we’ve let the digital world do as it will and tried to reconcile ourselves to the havoc it wreaks.
  • And one of the lessons of the last four years is that when you prize the digital design imperatives—lack of friction—over the human design imperatives—a need for friction—then bad things can happen.
  • We have an ongoing conflict between the design precepts of humans and the design precepts of computers.
  • Anyone who works with computers learns to fear their capacity to forget. Like so many things with computers, memory is strictly binary. There is either perfect recall or total oblivion, with nothing in between. It doesn't matter how important or trivial the information is. The computer can forget anything in an instant. If it remembers, it remembers for keeps.
  • This doesn't map well onto human experience of memory, which is fuzzy. We don't remember anything with perfect fidelity, but we're also not at risk of waking up having forgotten our own name. Memories tend to fade with time, and we remember only the more salient events.
  • And because we live in a time when storage grows ever cheaper, we learn to save everything, log everything, and keep it forever. You never know what will come in useful. Deleting is dangerous.
  • Our lives have become split between two worlds with two very different norms around memory.
  • [A] lot of what's wrong with the Internet has to do with memory. The Internet somehow contrives to remember too much and too little at the same time, and it maps poorly on our concepts of how memory should work.
  • The digital world is designed to never forget anything. It has perfect memory. Forever. So that one time you made a crude joke 20 years ago? It can now ruin your life.
  • Memory in the carbon-based world is imperfect. People forget things. That can be annoying if you’re looking for your keys but helpful if you’re trying to broker peace between two cultures. Or simply become a better person than you were 20 years ago.
  • The digital and carbon-based worlds have different design parameters. Marginal cost is one of them. Memory is another.

Why Do We Need to Sleep? - The Atlantic - 0 views

  • In a way, it’s startling how universal sleep is: In the midst of the hurried scramble for survival, across eons of bloodshed and death and flight, uncountable millions of living things have laid themselves down for a nice, long bout of unconsciousness. This hardly seems conducive to living to fight another day.
  • such a risky habit is so common, and so persistent, suggests that whatever is happening is of the utmost importance. Whatever sleep gives to the sleeper is worth tempting death over and over again, for a lifetime.
  • “What is so important that you risk being eaten, not eating yourself, procreation ... for this?”
  • ...4 more annotations...
  • Biologists call this need “sleep pressure”: Stay up too late, build up sleep pressure. Feeling drowsy in the evenings? Of course you are—by being awake all day, you’ve been generating sleep pressure! But like “dark matter,” this is a name for something whose nature we do not yet understand.
  • The search for the hypnotoxin was not unsuccessful. There are a handful of substances clearly demonstrated to cause sleep—including a molecule called adenosine, which appears to build up in certain parts of the brains of waking rats, then drain away during slumber. Adenosine is particularly interesting because it is adenosine receptors that caffeine seems to work on.
  • For instance, if adenosine puts us under at the moment of transition from wakefulness to sleep, where does it come from? “Nobody knows,” remarks Michael Lazarus, a researcher at the institute who studies adenosine. Some people say it’s coming from neurons, some say it’s another class of brain cells. But there isn’t a consensus. At any rate, “this isn’t about storage,” says Yanagisawa. In other words, these substances themselves don’t seem to store information about sleep pressure. They are just a response to it.
  • A few years ago, the group discovered a mouse that just could not seem to get rid of its sleep pressure. Its EEGs suggested it lived a life of snoozy exhaustion, and mice that had been engineered to carry its mutation showed the same symptoms. “This mutant has more high-amplitude sleep waves than normal. It’s always sleep-deprived,” says Yanagisawa. The mutation was in a gene called SIK3. The longer the mutants stay awake, the more chemical tags the SIK3 protein accumulates. The researchers published their discovery of the SIK3 mutants, as well as another sleep mutant, in Nature in 2016.

How Does Light Travel? - Universe Today - 0 views

  • However, there remains many fascinating and unanswered questions when it comes to light, many of which arise from its dual nature. For instance, how is it that light can be apparently without mass, but still behave as a particle? And how can it behave like a wave and pass through a vacuum, when all other waves require a medium to propagate?
  • This included rejecting Aristotle’s theory of light, which viewed it as being a disturbance in the air (one of his four “elements” that composed matter), and embracing the more mechanistic view that light was composed of indivisible atoms
  • In Young’s version of the experiment, he used a slip of paper with slits cut into it, and then pointed a light source at them to measure how light passed through it
  • ...6 more annotations...
  • 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!

Wikipedia acts as a check on Putin's false view of history - The Washington Post - 0 views

  • Whether to call Hitler gravely immoral or evil is one of literally hundreds of discussions about this article, which is among the most viewed ever on the site — more than 125 million times over the last 15 years, twice as many as Jesus’s total and in the neighborhood of the number for the soccer player Cristiano Ronaldo.
  • Setting the record straight matters because historical misinformation walks hand in hand with current disinformation.

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.

Avoidance, not anxiety, may be sabotaging your life - The Washington Post - 0 views

  • Anxiety, for many people, is like an unwelcome houseguest — a lingering presence that causes tension, clouds the mind with endless “what ifs” and shows up as various physical sensations.
  • About 12 percent of U.S. adults regularly felt worry, nervousness or anxiety, according to a National Health Interview Survey conducted between October and December 2022.
  • Anxiety, though, is not the puppeteer pulling the strings in many of our lives. There is a more subtle and insidious marionette, and it’s called psychological avoidance. When we avoid certain situations and decisions, it can lead to heightened anxiety and more problems.

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.

Instagram's Algorithm Delivers Toxic Video Mix to Adults Who Follow Children - WSJ - 0 views

  • Instagram’s Reels video service is designed to show users streams of short videos on topics the system decides will interest them, such as sports, fashion or humor. 
  • The Meta Platforms META -1.04%decrease; red down pointing triangle-owned social app does the same thing for users its algorithm decides might have a prurient interest in children, testing by The Wall Street Journal showed.
  • The Journal sought to determine what Instagram’s Reels algorithm would recommend to test accounts set up to follow only young gymnasts, cheerleaders and other teen and preteen influencers active on the platform.
  • ...30 more annotations...
  • 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.
