Pregnancy Changes the Brain in Ways That May Help Mothering - The New York Times - 0 views

  • Pregnancy changes a woman’s brain, altering the size and structure of areas involved in perceiving the feelings and perspectives of others, according to a first-of-its-kind study published Monday.
  • The results were remarkable: loss of gray matter in several brain areas involved in a process called social cognition or “theory of mind,” the ability to register and consider how other people perceive things.
  • A third possibility is that the loss is “part of the brain’s program for dealing with the future,” he said. Hormone surges in pregnancy might cause “pruning or cellular adaptation that is helpful,” he said, streamlining certain brain areas to be more efficient at mothering skills “from nurturing to extra vigilance to teaching.”

  • Pregnancy, she explained, may help a woman’s brain specialize in “a mother’s ability to recognize the needs of her infant, to recognize social threats or to promote mother-infant bonding.”
  • Researchers wanted to see if the women’s brain changes affected anything related to mothering. They found that relevant brain regions in mothers showed more activity when women looked at photos of their own babies than with photos of other children.
  • During another period of roiling hormonal change — adolescence — gray matter decreases in several brain regions that are believed to provide fine-tuning for the social, emotional and cognitive territory of being a teenager.
  • evidence against the common myth of ‘mommy brain.’
  •  
    Our brain changes during our lifetime to better fit our need. The decrease in gray matter in brain during pregnancy enables mothers to learn mothering skills fasters and be more focused on their own child. This aligns with the logic of evolution because newborns need a lot of attention and care from their mother. I am also very surprised to see that the similar thing also happens to teenager. The decrease in gray matter gives plasticity for teenagers to absorb new knowledge. It's so amazing that our brain is actually adjusting itself in different stages of life. --Sissi (12/20/2016)

All the Ways Your Wi-Fi Router Can Spy on You - The Atlantic - 0 views

  • But it can also be used to monitor humans—and in surprisingly detailed ways.
  • y analyzing the exact ways that a Wi-Fi signal is altered when a human moves through it, researchers can “see” what someone writes with their finger in the air, identify a particular person by the way that they walk, and even read a person’s lips with startling accuracy—in some cases even if a router isn’t in the same room as the person performing the actions.
  • Many researchers presented their Wi-Fi sensing technology as a way to preserve privacy while still capturing important data.

  • Ali said the system only works in controlled environments, and with rigorous training. “So, it is not a big privacy concern for now, no worries there,” wrote Ali, a Ph.D. student at Michigan State University, in an email.
  • Routers could soon keep kids and older adults safe, log daily activities, or make a smart home run more smoothly—but, if invaded by a malicious hacker, they could also be turned into incredibly sophisticated hubs for monitoring and surveillance.
  •  
    Everything has pros and cons. Gain always comes with loss. The development of new technology always comes with concerns. It reminded me of the scientific findings in quantum that leads to the invention of the atomic bombs. I think this wifi sensor technology can make our life much more convenient. Science enables us to see the world differently. --Sissi (1/25/2017)

What Have We Learned, If Anything? by Tony Judt | The New York Review of Books - 0 views

  • During the Nineties, and again in the wake of September 11, 2001, I was struck more than once by a perverse contemporary insistence on not understanding the context of our present dilemmas, at home and abroad; on not listening with greater care to some of the wiser heads of earlier decades; on seeking actively to forget rather than remember, to deny continuity and proclaim novelty on every possible occasion. We have become stridently insistent that the past has little of interest to teach us. Ours, we assert, is a new world; its risks and opportunities are without precedent.
  • the twentieth century that we have chosen to commemorate is curiously out of focus. The overwhelming majority of places of official twentieth-century memory are either avowedly nostalgo-triumphalist—praising famous men and celebrating famous victories—or else, and increasingly, they are opportunities for the recollection of selective suffering.
  • The problem with this lapidary representation of the last century as a uniquely horrible time from which we have now, thankfully, emerged is not the description—it was in many ways a truly awful era, an age of brutality and mass suffering perhaps unequaled in the historical record. The problem is the message: that all of that is now behind us, that its meaning is clear, and that we may now advance—unencumbered by past errors—into a different and better era.

  • Today, the “common” interpretation of the recent past is thus composed of the manifold fragments of separate pasts, each of them (Jewish, Polish, Serb, Armenian, German, Asian-American, Palestinian, Irish, homosexual…) marked by its own distinctive and assertive victimhood.
  • The resulting mosaic does not bind us to a shared past, it separates us from it. Whatever the shortcomings of the national narratives once taught in school, however selective their focus and instrumental their message, they had at least the advantage of providing a nation with past references for present experience. Traditional history, as taught to generations of schoolchildren and college students, gave the present a meaning by reference to the past: today’s names, places, inscriptions, ideas, and allusions could be slotted into a memorized narrative of yesterday. In our time, however, this process has gone into reverse. The past now acquires meaning only by reference to our many and often contrasting present concerns.
  • the United States thus has no modern memory of combat or loss remotely comparable to that of the armed forces of other countries. But it is civilian casualties that leave the most enduring mark on national memory and here the contrast is piquant indeed
  • Today, the opposite applies. Most people in the world outside of sub-Saharan Africa have access to a near infinity of data. But in the absence of any common culture beyond a small elite, and not always even there, the fragmented information and ideas that people select or encounter are determined by a multiplicity of tastes, affinities, and interests. As the years pass, each one of us has less in common with the fast-multiplying worlds of our contemporaries, not to speak of the world of our forebears.
  • What is significant about the present age of transformations is the unique insouciance with which we have abandoned not merely the practices of the past but their very memory. A world just recently lost is already half forgotten.
  • In the US, at least, we have forgotten the meaning of war. There is a reason for this. I
  • Until the last decades of the twentieth century most people in the world had limited access to information; but—thanks to national education, state-controlled radio and television, and a common print culture—within any one state or nation or community people were all likely to know many of the same things.
  • it was precisely that claim, that “it’s torture, and therefore it’s no good,” which until very recently distinguished democracies from dictatorships. We pride ourselves on having defeated the “evil empire” of the Soviets. Indeed so. But perhaps we should read again the memoirs of those who suffered at the hands of that empire—the memoirs of Eugen Loebl, Artur London, Jo Langer, Lena Constante, and countless others—and then compare the degrading abuses they suffered with the treatments approved and authorized by President Bush and the US Congress. Are they so very different?
  • As a consequence, the United States today is the only advanced democracy where public figures glorify and exalt the military, a sentiment familiar in Europe before 1945 but quite unknown today
  • the complacent neoconservative claim that war and conflict are things Americans understand—in contrast to naive Europeans with their pacifistic fantasies—seems to me exactly wrong: it is Europeans (along with Asians and Africans) who understand war all too well. Most Americans have been fortunate enough to live in blissful ignorance of its true significance.
  • That same contrast may account for the distinctive quality of much American writing on the cold war and its outcome. In European accounts of the fall of communism, from both sides of the former Iron Curtain, the dominant sentiment is one of relief at the closing of a long, unhappy chapter. Here in the US, however, the story is typically recorded in a triumphalist key.5
  • For many American commentators and policymakers the message of the twentieth century is that war works. Hence the widespread enthusiasm for our war on Iraq in 2003 (despite strong opposition to it in most other countries). For Washington, war remains an option—on that occasion the first option. For the rest of the developed world it has become a last resort.6
  • Ignorance of twentieth-century history does not just contribute to a regrettable enthusiasm for armed conflict. It also leads to a misidentification of the enemy.
  • This abstracting of foes and threats from their context—this ease with which we have talked ourselves into believing that we are at war with “Islamofascists,” “extremists” from a strange culture, who dwell in some distant “Islamistan,” who hate us for who we are and seek to destroy “our way of life”—is a sure sign that we have forgotten the lesson of the twentieth century: the ease with which war and fear and dogma can bring us to demonize others, deny them a common humanity or the protection of our laws, and do unspeakable things to them.
  • How else are we to explain our present indulgence for the practice of torture? For indulge it we assuredly do.
  • “But what would I have achieved by proclaiming my opposition to torture?” he replied. “I have never met anyone who is in favor of torture.”8 Well, times have changed. In the US today there are many respectable, thinking people who favor torture—under the appropriate circumstances and when applied to those who merit it.
  • American civilian losses (excluding the merchant navy) in both world wars amounted to less than 2,000 dead.
  • We are slipping down a slope. The sophistic distinctions we draw today in our war on terror—between the rule of law and “exceptional” circumstances, between citizens (who have rights and legal protections) and noncitizens to whom anything can be done, between normal people and “terrorists,” between “us” and “them”—are not new. The twentieth century saw them all invoked. They are the selfsame distinctions that licensed the worst horrors of the recent past: internment camps, deportation, torture, and murder—those very crimes that prompt us to murmur “never again.” So what exactly is it that we think we have learned from the past? Of what possible use is our self-righteous cult of memory and memorials if the United States can build its very own internment camp and torture people there?
  • We need to learn again—or perhaps for the first time—how war brutalizes and degrades winners and losers alike and what happens to us when, having heedlessly waged war for no good reason, we are encouraged to inflate and demonize our enemies in order to justify that war’s indefinite continuance.

Google's ChromeOS means losing control of data, warns GNU founder Richard Stallman | Te... - 0 views

  • Stallman, a computing veteran who is a strong advocate of free software via his Free Software Foundation, warned that making extensive use of cloud computing was "worse than stupidity" because it meant a loss of control of data.
  • The risks include loss of legal rights to data if it is stored on a company's machine's rather than your own, Stallman points out: "In the US, you even lose legal rights if you store your data in a company's machines instead of your own. The police need to present you with a search warrant to get your data from you; but if they are stored in a company's server, the police can get it without showing you anything. They may not even have to give the company a search warrant."
  • "I think that marketers like "cloud computing" because it is devoid of substantive meaning. The term's meaning is not substance, it's an attitude: 'Let any Tom, Dick and Harry hold your data, let any Tom, Dick and Harry do your computing for you (and control it).' Perhaps the term 'careless computing' would suit it better."

  • "healthy diet" as one containing lots of fruits and vegetables, nuts, fish, moderate alcohol use and minimal red meat
  • "We just wanted to look at a diverse cohort of people from all around the world and analyze what their risk for cognitive decline would be if they consumed what most organizations would consider a 'healthy diet',"
  • this new study suggests that improving overall diet quality is an important factor for lowering the risk of memory and thinking loss
  • participants with the healthiest diets were 24% less likely to experience cognitive decline compared to those with the least healthy diets. These individuals were slightly older in age, more active, less likely to smoke and had a lower BMI.

Ta-Nehisi Coates's 'Letter to My Son' - The Atlantic - 0 views

  • The question is not whether Lincoln truly meant “government of the people” but what our country has, throughout its history, taken the political term “people” to actually mean. In 1863 it did not mean your mother or your grandmother, and it did not mean you and me.
  • When the journalist asked me about my body, it was like she was asking me to awaken her from the most gorgeous dream. I have seen that dream all my life. It is perfect houses with nice lawns. It is Memorial Day cookouts, block associations, and driveways. The Dream is tree houses and the Cub Scouts. And for so long I have wanted to escape into the Dream, to fold my country over my head like a blanket. But this has never been an option, because the Dream rests on our backs, the bedding made from our bodies.
  • The destroyers will rarely be held accountable. Mostly they will receive pensions.

  • you know now, if you did not before, that the police departments of your country have been endowed with the authority to destroy your body. It does not matter if the destruction is the result of an unfortunate overreaction. It does not matter if it originates in a misunderstanding. It does not matter if the destruction springs from a foolish policy
  • But a society that protects some people through a safety net of schools, government-backed home loans, and ancestral wealth but can only protect you with the club of criminal justice has either failed at enforcing its good intentions or has succeeded at something much darker.
  • It is hard to face this. But all our phrasing—race relations, racial chasm, racial justice, racial profiling, white privilege, even white supremacy—serves to obscure that racism is a visceral experience, that it dislodges brains, blocks airways, rips muscle, extracts organs, cracks bones, breaks teeth
  • ou must never look away from this. You must always remember that the sociology, the history, the economics, the graphs, the charts, the regressions all land, with great violence, upon the body.
  • And should one live in such a body? What should be our aim beyond meager survival of constant, generational, ongoing battery and assault? I have asked this question all my life.
  • The question is unanswerable, which is not to say futile. The greatest reward of this constant interrogation, of confrontation with the brutality of my country, is that it has freed me from ghosts and myths.
  • I was afraid long before you, and in this I was unoriginal. When I was your age the only people I knew were black, and all of them were powerfully, adamantly, dangerously afraid. It was always right in front of me. The fear was there in the extravagant boys of my West Baltimore neighborhood
  • The fear lived on in their practiced bop, their slouching denim, their big T- shirts, the calculated angle of their baseball caps, a catalog of behaviors and garments enlisted to inspire the belief that these boys were in firm possession of everything they desired.
  • To be black in the Baltimore of my youth was to be naked before the elements of the world, before all the guns, fists, knives, crack, rape, and disease. The law did not protect us. And now, in your time, the law has become an excuse for stopping and frisking you, which is to say, for furthering the assault on your body
  • I remember being amazed that death could so easily rise up from the nothing of a boyish afternoon, billow up like fog. I knew that West Baltimore, where I lived; that the north side of Philadelphia, where my cousins lived; that the South Side of Chicago, where friends of my father lived, comprised a world apart. Somewhere out there beyond the firmament, past the asteroid belt, there were other worlds where children did not regularly fear for their bodies
  • here will surely always be people with straight hair and blue eyes, as there have been for all history. But some of these straight-haired people with blue eyes have been “black,” and this points to the great difference between their world and ours. We did not choose our fences. They were imposed on us by Virginia planters obsessed with enslaving as many Americans as possible. Now I saw that we had made something down here, in slavery, in Jim Crow, in ghettoes. At The Mecca I saw how we had taken their one-drop rule and flipped it. They made us into a race. We made ourselves into a people.
  • I came to understand that my country was a galaxy, and this galaxy stretched from the pandemonium of West Baltimore to the happy hunting grounds of Mr. Belvedere. I obsessed over the distance between that other sector of space and my own. I knew that my portion of the American galaxy, where bodies were enslaved by a tenacious gravity, was black and that the other, liberated portion was not. I knew that some inscrutable energy preserved the breach. I felt, but did not yet understand, the relation between that other world and me. And I felt in this a cosmic injustice, a profound cruelty, which infused an abiding, irrepressible desire to unshackle my body and achieve the velocity of escape.
  • Before I could escape, I had to survive, and this could only mean a clash with the streets, by which I mean not just physical blocks, nor simply the people packed into them, but the array of lethal puzzles and strange perils which seem to rise up from the asphalt itself. The streets transform every ordinary day into a series of trick questions, and every incorrect answer risks a beat-down, a shooting, or a pregnancy. No one survives unscathed
  • When I was your age, fully one-third of my brain was concerned with who I was walking to school with, our precise number, the manner of our walk, the number of times I smiled, who or what I smiled at, who offered a pound and who did not—all of which is to say that I practiced the culture of the streets, a culture concerned chiefly with securing the body.
  • Why were only our heroes nonviolent? Back then all I could do was measure these freedom-lovers by what I knew. Which is to say, I measured them against children pulling out in the 7-Eleven parking lot, against parents wielding extension cords, and the threatening intonations of armed black gangs saying, “Yeah, nigger, what’s up now?” I judged them against the country I knew, which had acquired the land through murder and tamed it under slavery, against the country whose armies fanned out across the world to extend their dominion. The world, the real one, was civilization secured and ruled by savage means. How could the schools valorize men and women whose values society actively scorned? How could they send us out into the streets of Baltimore, knowing all that they were, and then speak of nonviolence?
  • the beauty of the black body was never celebrated in movies, in television, or in the textbooks I’d seen as a child. Everyone of any import, from Jesus to George Washington, was white. This was why your grandparents banned Tarzan and the Lone Ranger and toys with white faces from the house. They were rebelling against the history books that spoke of black people only as sentimental “firsts”—first black four-star general, first black congressman, first black mayor—always presented in the bemused manner of a category of Trivial Pursuit.
  • erious history was the West, and the West was white. This was all distilled for me in a quote I once read, from the novelist Saul Bellow. I can’t remember where I read it, or when—only that I was already at Howard. “Who is the Tolstoy of the Zulus?,” Bellow quipped
  • this view of things was connected to the fear that passed through the generations, to the sense of dispossession. We were black, beyond the visible spectrum, beyond civilization. Our history was inferior because we were inferior, which is to say our bodies were inferior. And our inferior bodies could not possibly be accorded the same respect as those that built the West. Would it not be better, then, if our bodies were civilized, improved, and put to some legitimate Christian use?
  • now I looked back on my need for a trophy case, on the desire to live by the standards of Saul Bellow, and I felt that this need was not an escape but fear again—fear that “they,” the alleged authors and heirs of the universe, were right. And this fear ran so deep that we accepted their standards of civilization and humanity.
  • “Tolstoy is the Tolstoy of the Zulus,” wrote Wiley. “Unless you find a profit in fencing off universal properties of mankind into exclusive tribal ownership.” And there it was. I had accepted Bellow’s premise. In fact, Bellow was no closer to Tolstoy than I was to Nzinga. And if I were closer it would be because I chose to be, not because of destiny written in DNA. My great error was not that I had accepted someone else’s dream but that I had accepted the fact of dreams, the need for escape, and the invention of racecraft.
  • still and all I knew that we were something, that we were a tribe—on one hand, invented, and on the other, no less real. The reality was out there on the Yard, on the first warm day of spring when it seemed that every sector, borough, affiliation, county, and corner of the broad diaspora had sent a delegate to the great world party
  • I could see now that that world was more than a photonegative of that of the people who believe they are white. “White America” is a syndicate arrayed to protect its exclusive power to dominate and control our bodies. Sometimes this power is direct (lynching), and sometimes it is insidious (redlining). But however it appears, the power of domination and exclusion is central to the belief in being white, and without it, “white people” would cease to exist for want of reasons
  • There is nothing uniquely evil in these destroyers or even in this moment. The destroyers are merely men enforcing the whims of our country, correctly interpreting its heritage and legacy. This legacy aspires to the shackling of black bodies
  • Think of all the embraces, all the private jokes, customs, greetings, names, dreams, all the shared knowledge and capacity of a black family injected into that vessel of flesh and bone. And think of how that vessel was taken, shattered on the concrete, and all its holy contents, all that had gone into each of them, was sent flowing back to the earth. It is terrible to truly see our particular beauty, Samori, because then you see the scope of the loss. But you must push even further. You must see that this loss is mandated by the history of your country, by the Dream of living white.
  • I don’t know if you remember how the film we saw at the Petersburg Battlefield ended as though the fall of the Confederacy were the onset of a tragedy, not jubilee. I doubt you remember the man on our tour dressed in the gray wool of the Confederacy, or how every visitor seemed most interested in flanking maneuvers, hardtack, smoothbore rifles, grapeshot, and ironclads, but virtually no one was interested in what all of this engineering, invention, and design had been marshaled to achieve. You were only 10 years old. But even then I knew that I must trouble you, and this meant taking you into rooms where people would insult your intelligence, where thieves would try to enlist you in your own robbery and disguise their burning and looting as Christian charity. But robbery is what this is, what it always was.
  • American reunion was built on a comfortable narrative that made enslavement into benevolence, white knights of body snatchers, and the mass slaughter of the war into a kind of sport in which one could conclude that both sides conducted their affairs with courage, honor, and élan. This lie of the Civil War is the lie of innocence, is the Dream.
  • I, like every kid I knew, loved The Dukes of Hazzard. But I would have done well to think more about why two outlaws, driving a car named the General Lee, must necessarily be portrayed as “just some good ole boys, never meanin’ no harm”—a mantra for the Dreamers if there ever was one. But what one “means” is neither important nor relevant. It is not necessary that you believe that the officer who choked Eric Garner set out that day to destroy a body. All you need to understand is that the officer carries with him the power of the American state and the weight of an American legacy, and they necessitate that of the bodies destroyed every year, some wild and disproportionate number of them will be black.
  • Here is what I would like for you to know: In America, it is traditional to destroy the black body—it is heritage. Enslavement was not merely the antiseptic borrowing of labor—it is not so easy to get a human being to commit their body against its own elemental interest. And so enslavement must be casual wrath and random manglings, the gashing of heads and brains blown out over the river as the body seeks to escape. It must be rape so regular as to be industrial. There is no uplifting way to say this.
  • It had to be blood. It had to be the thrashing of kitchen hands for the crime of churning butter at a leisurely clip. It had to be some woman “chear’d ... with thirty lashes a Saturday last and as many more a Tuesday again.” It could only be the employment of carriage whips, tongs, iron pokers, handsaws, stones, paperweights, or whatever might be handy to break the black body, the black family, the black community, the black nation. The bodies were pulverized into stock and marked with insurance. And the bodies were an aspiration, lucrative as Indian land, a veranda, a beautiful wife, or a summer home in the mountains. For the men who needed to believe themselves white, the bodies were the key to a social club, and the right to break the bodies was the mark of civilization.
  • “The two great divisions of society are not the rich and poor, but white and black,” said the great South Carolina senator John C. Calhoun. “And all the former, the poor as well as the rich, belong to the upper class, and are respected and treated as equals.” And there it is—the right to break the black body as the meaning of their sacred equality. And that right has always given them meaning, has always meant that there was someone down in the valley because a mountain is not a mountain if there is nothing below.
  • There is no them without you, and without the right to break you they must necessarily fall from the mountain, lose their divinity, and tumble out of the Dream. And then they would have to determine how to build their suburbs on something other than human bones, how to angle their jails toward something other than a human stockyard, how to erect a democracy independent of cannibalism. I would like to tell you that such a day approaches when the people who believe themselves to be white renounce this demon religion and begin to think of themselves as human. But I can see no real promise of such a day. We are captured, brother, surrounded by the majoritarian bandits of America. And this has happened here, in our only home, and the terrible truth is that we cannot will ourselves to an escape on our own.
  • I think now of the old rule that held that should a boy be set upon in someone else’s chancy hood, his friends must stand with him, and they must all take their beating together. I now know that within this edict lay the key to all living. None of us were promised to end the fight on our feet, fists raised to the sky. We could not control our enemies’ number, strength, or weaponry. Sometimes you just caught a bad one. But whether you fought or ran, you did it together, because that is the part that was in our control. What we must never do is willingly hand over our own bodies or the bodies of our friends. That was the wisdom: We knew we did not lay down the direction of the street, but despite that, we could—and must—fashion the way of our walk. And that is the deeper meaning of your name—that the struggle, in and of itself, has meaning.
  • I have raised you to respect every human being as singular, and you must extend that same respect into the past. Slavery is not an indefinable mass of flesh. It is a particular, specific enslaved woman, whose mind is as active as your own, whose range of feeling is as vast as your own; who prefers the way the light falls in one particular spot in the woods, who enjoys fishing where the water eddies in a nearby stream, who loves her mother in her own complicated way, thinks her sister talks too loud, has a favorite cousin, a favorite season, who excels at dressmaking and knows, inside herself, that she is as intelligent and capable as anyone. “Slavery” is this same woman born in a world that loudly proclaims its love of freedom and inscribes this love in its essential texts, a world in which these same professors hold this woman a slave, hold her mother a slave, her father a slave, her daughter a slave, and when this woman peers back into the generations all she sees is the enslaved. She can hope for more. She can imagine some future for her grandchildren. But when she dies, the world—which is really the only world she can ever know—ends. For this woman, enslavement is not a parable. It is damnation. It is the never-ending night. And the length of that night is most of our history. Never forget that we were enslaved in this country longer than we have been free. Never forget that for 250 years black people were born into chains—whole generations followed by more generations who knew nothing but chains.
  • You must resist the common urge toward the comforting narrative of divine law, toward fairy tales that imply some irrepressible justice. The enslaved were not bricks in your road, and their lives were not chapters in your redemptive history. They were people turned to fuel for the American machine. Enslavement was not destined to end, and it is wrong to claim our present circumstance—no matter how improved—as the redemption for the lives of people who never asked for the posthumous, untouchable glory of dying for their children. Our triumphs can never redeem this. Perhaps our triumphs are not even the point. Perhaps struggle is all we have
  • I am not a cynic. I love you, and I love the world, and I love it more with every new inch I discover. But you are a black boy, and you must be responsible for your body in a way that other boys cannot know. Indeed, you must be responsible for the worst actions of other black bodies, which, somehow, will always be assigned to you. And you must be responsible for the bodies of the powerful—the policeman who cracks you with a nightstick will quickly find his excuse in your furtive movements. You have to make your peace with the chaos, but you cannot lie.
  • “I could have you arrested,” he said. Which is to say: “One of your son’s earliest memories will be watching the men who sodomized Abner Louima and choked Anthony Baez cuff, club, tase, and break you.” I had forgotten the rules, an error as dangerous on the Upper West Side of Manhattan as on the West Side of Baltimore. One must be without error out here. Walk in single file. Work quietly. Pack an extra No. 2 pencil. Make no mistakes.
  • the price of error is higher for you than it is for your countrymen, and so that America might justify itself, the story of a black body’s destruction must always begin with his or her error, real or imagined—with Eric Garner’s anger, with Trayvon Martin’s mythical words (“You are gonna die tonight”), with Sean Bell’s mistake of running with the wrong crowd, with me standing too close to the small-eyed boy pulling out.
  • You are called to struggle, not because it assures you victory but because it assures you an honorable and sane life
  • I am sorry that I cannot save you—but not that sorry. Part of me thinks that your very vulnerability brings you closer to the meaning of life, just as for others, the quest to believe oneself white divides them from it. The fact is that despite their dreams, their lives are also not inviolable. When their own vulnerability becomes real—when the police decide that tactics intended for the ghetto should enjoy wider usage, when their armed society shoots down their children, when nature sends hurricanes against their cities—they are shocked by the rages of logic and the natural world in a way that those of us who were born and bred to understand cause and effect can never be.
  • I would not have you live like them. You have been cast into a race in which the wind is always at your face and the hounds are always at your heels. And to varying degrees this is true of all life. The difference is that you do not have the privilege of living in ignorance of this essential fact.
  • I never wanted you to be twice as good as them, so much as I have always wanted you to attack every day of your brief bright life determined to struggle. The people who must believe they are white can never be your measuring stick. I would not have you descend into your own dream. I would have you be a conscious citizen of this terrible and beautiful world.

Moral Enhancement | Issue 91 | Philosophy Now - 0 views

What is to be done to counter these threats?

We discount the distant future in making judgements, and can only empathise with a few individuals based on their proximity or similarity to us, rather than, say, on the basis of their situations. So our ability to cooperate, applying our notions of fairness and justice, is limited to our circle, a small circle of family and friends.

Climate activism is doomed if it remains a left-only issue | Jonathan Freedland | Comme... - 0 views

  • When candid, news editors and TV producers admit they presume their audience files climate change under “worthy but dull”. They know they should care, but they struggle.
  • For the media, climate change is Kryptonite. It fails to tick almost every one of the boxes that defines a story. For one thing, it’s not new: it’s a perennial part of the background noise of 21st-century life.
  • Cognitive psychologists speak of “loss aversion”: when presented with a choice between a relatively small sacrifice now and an uncertain but larger loss a generation from now, human beings rarely make the apparently obvious and rational move, to make the sacrifice. Add to that our “optimism bias”: the tendency to assume that all will be well in the end – that “they” will think of some whizzy technical fix to keep the world’s temperature stable, and humanity will dodge the bullet.

  • But that still leaves what may be the largest political challenge. Right now, climate change has become an issue of the left.

The Panic of 2020? Oh, I Made a Ton of Money-and So Did You - WSJ - 0 views

  • In a classic experiment in 1972, researchers asked people to estimate the likelihood that various positive and negative outcomes might result from President Richard Nixon’s upcoming trips to China and Russia that year. We now call those visits “historic” because they thawed decades of hostility between the U.S. and the communist powers. In advance, no one knew whether the trips would accomplish anything.

My Mom Believes In QAnon. I've Been Trying To Get Her Out. - 0 views

  • An early adopter of the QAnon mass delusion, on board since 2018, she held firm to the claim that a Satan-worshipping cabal of child sex traffickers controlled the world and the only person standing in their way was Trump. She saw him not merely as a politician but a savior, and she expressed her devotion in stark terms.
  • “The prophets have said Trump is anointed,” she texted me once. “God is using him to finally end the evil doings of the cabal which has hurt humanity all these centuries… We are in a war between good & evil.”
  • By 2020, I’d pretty much given up on swaying my mom away from her preferred presidential candidate. We’d spent many hours arguing over basic facts I considered indisputable. Any information I cited to prove Trump’s cruelty, she cut down with a corresponding counterattack. My links to credible news sources disintegrated against a wall of outlets like One America News Network, Breitbart, and Before It’s News. Any cracks I could find in her positions were instantly undermined by the inconvenient fact that I was, in her words, a member of “the liberal media,” a brainwashed acolyte of the sprawling conspiracy trying to take down her heroic leader.
  • ...20 more annotations...
  • The irony gnawed at me: My entire vocation as an investigative reporter was predicated on being able to reveal truths, and yet I could not even rustle up the evidence to convince my own mother that our 45th president was not, in fact, the hero she believed him to be. Or, for that matter, that John F. Kennedy Jr. was dead. Or that Tom Hanks had not been executed for drinking the blood of children.
  • The theories spun from Q’s messages seemed much easier to disprove. Oprah Winfrey couldn’t have been detained during a wave of deep state arrests because we could still see her conducting live interviews on television. Trump’s 4th of July speech at Mount Rushmore came to an end without John F. Kennedy Jr. revealing he was alive and stepping in as the president’s new running mate. The widespread blackouts that her Patriot friend’s “source from the Pentagon” had warned about failed to materialize. And I could testify firsthand that the CIA had no control over my newsroom’s editorial decisions.
  • “I believe the Holy Spirit led me to the QAnons to discover the truth which is being suppressed,” she texted me. “Otherwise, how would I be able to know the truth if the lamestream media suppresses the truth?”
  • Through the years, I’d battled against conspiracy theories my mom threw at me that were far more formidable than QAnon. I’d been stumped when she asked me to prove that Beyoncé wasn’t an Illuminati member, dumbfounded when research studies I sent her weren’t enough to reach an agreement on vaccine efficacy, and too worn down to say anything more than “that’s not true” when confronted with false allegations of murders committed by prominent politicians.
  • Eventually, I accepted the impasse. It didn’t seem healthy that every conversation we had would devolve into a circuitous debate about which one of us was on the side of the bad guys. So I tried to pick my battles.
  • But what I had dismissed as damaging inconsistencies turned out to be the core strength of the belief system: It was alive, flexible, sprouting more questions than answers, more clues to study, an investigation playing out in real time, with the fate of the world at stake.
  • With no overlap between our filters of reality, I was at a loss for any facts that would actually stick.
  • Meanwhile, she wondered where she’d gone wrong with me
  • She regretted not taking politics more seriously when I was younger. I’d grown up blinkered by American privilege, trained to ignore the dirty machinations securing my comforts. My mom had shed that luxury long ago.
  • The year my mom began falling down QAnon rabbit holes, I turned the age she was when she first arrived in the States. By then, I was no longer sure that America was worth the cost of her migration. When the real estate market collapsed under the weight of Wall Street speculation, she had to sell our house at a steep loss to avoid foreclosure and her budding career as a realtor evaporated. Her near–minimum wage jobs weren’t enough to cover her bills, so her credit card debts rose. She delayed retirement plans because she saw no path to breaking even anytime soon, though she was hopeful that a turnaround was on the horizon. Through the setbacks and detours, she drifted into the arms of the people and beliefs I held most responsible for her troubles.
  • With a fervor I knew was futile, I’d tell my mom she was missing the real conspiracy: The powerful people shaping policy to benefit their own interests, to maintain wealth and white predominance, through tax cuts and voter suppression, were commandeering her support solely by catering to her stance on the one issue she cared most about.
  • The voice my mom trusted most now was Trump’s. Our disagreements were no longer ideological to her but part of a celestial conflict.
  • “I love you but you have to be on the side of good,” she texted me. “Im sad cuz u have become part of the deep state. May God have mercy on you...I pray you will see the truth of the evil agenda and be on the side of Trump.”
  • She likened her fellow Patriots to the early Christians who spread the word of Jesus at the risk of persecution. She often sent me a meme with a caption about “ordinary people who spent countless hours researching, debating, meditating and praying” for the truth to be revealed to them. “Although they were mocked, dismissed and cast off, they knew their souls had agreed long ago to do this work.”
  • Last summer, as my mom marched in a pink MAGA hat amid maskless crowds, and armed extremists stalked racial justice protests, and a disputed election loomed like a time bomb, I entertained my darkest thoughts about the fate of our country. Was there any hope in a democracy without a shared set of basic facts? Had my elders fled one authoritarian regime only for their children to face another? Amid the gloom, I found only a single morsel of solace: My mom was as hopeful as she’d ever been.
  • I wish I could offer some evidence showing that the gulf between us might be narrowing, that my love, persistence, and collection of facts might be enough to draw her back into a reality we share, and that when our wager about the storm comes due in a few months, she’ll realize that the voices she trusts have been lying to her. But I don’t think that will happen
  • What can I do but try to limit the damage? Send my mom movie recommendations to occupy the free time she instead spends on conspiracy research. Shift our conversations to the common ground of cooking recipes and family gossip. Raise objections when her beliefs nudge her toward dangerous decisions.
  • I now understand our debates as marks of the very bond I thought was disintegrating. No matter how far she believes I’ve fallen into the deep state, how hard I fight for the forces of evil, how imminent the grand plan’s rapture, my mom will be there on the other side of the line putting in a good word for me with the angels and saints, trying to save me from damnation. And those are the two realities we live in. ●

Opinion | How Fear Distorts Our Thinking About the Coronavirus - The New York Times - 0 views

  • When it comes to making decisions that involve risks, we humans can be irrational in quite systematic ways — a fact that the psychologists Amos Tversky and Daniel Kahneman famously demonstrated with the help of a hypothetical situation, eerily apropos of today’s coronavirus epidemic, that has come to be known as the Asian disease problem.
  • This is irrational because the two questions don’t differ mathematically. In both cases, choosing the first option means accepting the certainty that 200 people live, and choosing the second means embracing a one-third chance that all could be saved with an accompanying two-thirds chance that all will die. Yet in our minds, Professors Tversky and Kahneman explained, losses loom larger than gains, and so when the options are framed in terms of deaths rather than cures, we’ll accept more risks to try to avoid deaths.
  • Our decision making is bad enough when the disease is hypothetical. But when the disease is real — when we see actual death tolls climbing daily, as we do with the coronavirus — another factor besides our sensitivity to losses comes into play: fear.

  • The brain states we call emotions exist for one reason: to help us decide what to do next. They reflect our mind’s predictions for what’s likely to happen in the world and therefore serve as an efficient way to prepare us for it. But when the emotions we feel aren’t correctly calibrated for the threat or when we’re making judgments in domains where we have little knowledge or relevant information, our feelings become more likely to lead us astray.

  • there are many reasons our tree canopy is declining, including hurricanes, tornadoes, fires, insects and disease.
  • But the one reason for tree loss that humans can control is sensible development.
  • “Every time we put a road down, we put a building and we cut a tree or add a tree, it not only affects that site, it affects the region.”
  • The study placed a value on tree loss based on trees’ role in air pollution removal and energy conservation. The lost value amounted to $96 million a year.
  • Trees provide shade for homes, office buildings, parks and roadways, cooling surface temperatures.
  • Trees absorb carbon and remove pollutants from the atmosphere.
  • Trees reduce energy costs by $4 billion a year, according to Nowak’s study.
  • Trees act as water filters, taking in dirty surface water and absorbing nitrogen and phosphorus into the soil.
  • Trees reduce flooding by absorbing water and reducing runoff into streams.
  • Trees can deflect sound
  • Trees absorb 96% of ultraviolet radiation, Nowak says.
  • Many studies have found connections between exposure to nature and better mental and physical health.
  • And studies have associated living near green areas with lower death rates.
  • Worldwide, forests provide for a huge diversity of animal life.
  • there’s a downside to trees too, such as pollen allergies or large falling branches in storms, “and people don’t like raking leaves.”
  • Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt.
  • Don’t remove old trees if it’s not necessary: Instead, try taking smaller actions like removing branches.

Covid Didn't Start the Mental-Health Crisis - WSJ - 0 views

  • There’s a consensus that the Covid-19 pandemic and lockdowns have created a mental-health crisis, as increasing numbers of children and adolescents suffer with depression, anxiety and suicidal thoughts. It’s more accurate to say that Covid exacerbated a crisis that was already building.
  • the way to protect children’s mental well-being in the long term is strong parental care from an early age.
  • Many stressors play a role in the current mental health crisis: academic and social pressure, unrealistic parental expectations, political and financial instability, the overpowering presence of social media and other technology, and the loss of community in favor of individualism.
  • ...10 more annotations...
  • Previous generations faced poverty, unemployment, war and racial injustice. So why is the current adversity causing so much mental distress?
  • A major reason is that we have devalued the work of parents. Mothers and fathers are less present for their children physically and emotionally, starting in early childhood and throughout adolescence, and this diminishes a child’s resilience and emotional fortitude throughout life
  • Children aren’t born resilient but neurologically and emotionally fragile.
  • Neuroscience research over the past 30 years has demonstrated how vulnerable an infant’s developing brain is to stress. Studies suggest that early maternal care has long-term effects on stress regulation and resilience, and that attachment patterns formed in early childhood are enduring and long-lasting.
  • Children acutely need parents more than ever in the first three years, and daycare is usually a bad environment for this age group.
  • Building resilience to stress is a slow process of ensuring that children develop emotional security through the constant presence of their primary attachment figure, usually the mother, to withstand incremental amounts of frustration and loss.
  • As a society we have abandoned the care of children to institutional or group care, we have exposed them to early separation from parents’ physical and emotional presence, and we have prioritized financial success and careers over children
  • The government has promoted and pushed the importance of economic productivity and working outside the home and devalued nurturing.
  • We have put less emphasis on caring for and being present for children while simultaneously expecting more from them academically, socially and in all of their extracurricular interests.
  • That’s why it’s a mistake to blame Covid for the children’s mental-health crisis. Covid merely magnified existing family dynamics. If a family was healthy and emotionally secure, Covid tended to bring it together. If a family was struggling, in conflict or dysfunctional, Covid magnified those difficulties.

Why the modern world is bad for your brain | Science | The Guardian - 0 views

  • Our brains are busier than ever before. We’re assaulted with facts, pseudo facts, jibber-jabber, and rumour, all posing as information. Trying to figure out what you need to know and what you can ignore is exhausting.
  • Our smartphones have become Swiss army knife–like appliances that include a dictionary, calculator, web browser, email, Game Boy, appointment calendar, voice recorder, guitar tuner, weather forecaster, GPS, texter, tweeter, Facebook updater, and flashlight.
  • But there’s a fly in the ointment. Although we think we’re doing several things at once, multitasking, this is a powerful and diabolical illusion.
  • ...12 more annotations...
  • When people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost in doing so.”
  • Even though we think we’re getting a lot done, ironically, multitasking makes us demonstrably less efficient.
  • Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation.
  • The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted.
  • Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.
  • His research found that being in a situation where you are trying to concentrate on a task, and an email is sitting unread in your inbox, can reduce your effective IQ by 10 points.
  • Wilson showed that the cognitive losses from multitasking are even greater than the cognitive losses from pot‑smoking.
  • If students study and watch TV at the same time, for example, the information from their schoolwork goes into the striatum, a region specialised for storing new procedures and skills, not facts and ideas. Without the distraction of TV, the information goes into the hippocampus, where it is organised and categorised in a variety of ways, making it easier to retrieve.
  • All this activity gives us a sense that we’re getting things done – and in some cases we are. But we are sacrificing efficiency and deep concentration when we interrupt our priority activities with email.
  • This uncertainty wreaks havoc with our rapid perceptual categorisation system, causes stress, and leads to decision overload. Every email requires a decision! Do I respond to it? If so, now or later? How important is it? What will be the social, economic, or job-related consequences if I don’t answer, or if I don’t answer right now?
  • A lever in the cage allowed the rats to send a small electrical signal directly to their nucleus accumbens. Do you think they liked it? Boy how they did! They liked it so much that they did nothing else. They forgot all about eating and sleeping. Long after they were hungry, they ignored tasty food if they had a chance to press that little chrome bar;
  • But remember, it is the dumb, novelty-seeking portion of the brain driving the limbic system that induces this feeling of pleasure, not the planning, scheduling, higher-level thought centres in the prefrontal cortex. Make no mistake: email-, Facebook- and Twitter-checking constitute a neural addiction.
