Out-Of-Body Experiences: Mine Is Finally Explained | Psychology Today - 0 views

  • Sleep deprivation had disturbed my vestibular system, making me feel drifting or floating, and had especially interfered with my right TPJ and with it my body schema (Chee & Chua 2007, Quarck et al 2006). Nearly four hours of holding out my arm for the Ouija board had confused my body schema even more. My attention kept wandering and my short term memory was reduced by cannabis (Earleywine 2002).
  • With my hyperexcitable cortex (Braithwaite et al 2013) already disinhibited by the combination of sleep deprivation and cannabis, it went into random firing, producing an illusory central light and the form constants of spirals and tunnels (Cowan 1982). Disinhibited motion detectors produced illusory movement and as the light grew bigger I seemed to move towards it
  • My auditory cortex was similarly hyperactive, producing random low-frequency repetitive sounds that drowned out the music. It sounded to me like the pounding of horses’ hooves. I was galloping fast down the tunnel towards the light.

  • ‘Where are you, Sue?’ I was brought up short. I tried to picture my own body and where it really was, but my prefrontal cortex was deactivated as the brain hovered on the edge of sleep (Muzur et al 2002). With my TPJ disturbed it was impossible to combine a body schema with vestibular and sensory input to give a firm sense of an embodied self (Blanke et al 2002).
  • The roofs, gutters and chimneys I saw were just as I imagined them, not as they were. So were the cities, lakes, oceans and islands I saw. I laughed at the vivid ‘star-shaped island with a hundred trees’, believing it was a thought-form in the astral plane (Besent 1896, Findlay 1931) because that was the only theory I knew.
  • I was too tired to do more than glimpse this new vastness. In exhaustion, I seemed to face a choice, to stay in this marvelous, right-seeming, perfect state, or return to ordinary life. The choice made itself and the struggle began. After more than two hours of serious disturbance, this brain took some time to reinstate both body schema and self-image and even then confused my own body with others. When I opened my eyes I felt and saw greyish body-shapes around the others as well as myself; displaced body schemas that gradually faded until I was (more or less) back to normal. Yet nothing was ever quite the same again.”
  • But that’s the joy of doing science at all. I have not, in these posts, covered the tunnel experience, the silver cord and several other features more commonly found during near-death experiences, but I may return to them in future. For now I hope you have enjoyed this series of OBE stories.

The Number of Countries in the World - 0 views

  • The United Nations, for example, recognizes more than 240 countries and territories. The United States, however, officially recognizes fewer than 200 nations. Ultimately, the best answer is that there are 196 countries in the world.
  • The island of Taiwan, formally known as the Republic of China, meets the requirements for an independent country or state status. However, all but a handful of nations refuse to recognize Taiwan as an independent nation. The political reasons for this date back to the late 1940s, when the Republic of China was ousted from mainland China by Mao Tse Tung's communist rebels, and ROC leaders fled to Taiwan. The communist People's Republic of China maintains that it has authority over Taiwan, and relations between the island and mainland have been strained.
  • Taiwan was actually a member of the United Nations (and even the Security Council) until 1971 when mainland China replaced Taiwan in the organization.

  • There also are dozens of territories and colonies that are sometimes erroneously called countries but don't count because they're governed by other countries
  • If you use the U.S. State Department's list of recognized nations and also include Taiwan there are 196 countries in the world, which is probably the best current answer to the question.

Gamblers, Scientists and the Mysterious Hot Hand - The New York Times - 0 views

  • Psychologists who study how the human mind responds to randomness call this the gambler’s fallacy — the belief that on some cosmic plane a run of bad luck creates an imbalance that must ultimately be corrected, a pressure that must be relieved
  • The opposite of that is the hot-hand fallacy — the belief that winning streaks, whether in basketball or coin tossing, have a tendency to continue
  • Both misconceptions are reflections of the brain’s wired-in rejection of the power that randomness holds over our lives. Look deep enough, we instinctively believe, and we may uncover a hidden order.
  • ...11 more annotations...
  • A working paper published this summer has caused a stir by proposing that a classic body of research disproving the existence of the hot hand in basketball is flawed by a subtle misperception about randomness. If the analysis is correct, the possibility remains that the hot hand is real.
  • We mortals can benefit, at least in theory, from islands of predictability — a barely perceptible tilt of a roulette table that makes the ball slightly more likely to land on one side of the wheel than the other
  • The same is true for the random walk of the stock market. Becoming aware of information before it has propagated worldwide can give a speculator a tiny, temporary edge. Some traders pay a premium to locate their computer servers as close as possible to Lower Manhattan, gaining advantages measured in microseconds.
  • Taken to extremes, seeing connections that don’t exist can be a symptom of a psychiatric condition called apophenia. In less pathological forms, the brain’s hunger for pattern gives rise to superstitions (astrology, numerology) and is a driving factor in what has been called a replication crisis in science
  • I know it sounds crazy but when you average the scores together the answer is not 50-50, as most people would expect, but about 40-60 in favor of tails.
  • There is not, as Guildenstern might imagine, a tear in the fabric of space-time. It remains as true as ever that each flip is independent, with even odds that the coin will land one way or the other. But by concentrating on only some of the data — the flips that follow heads — a gambler falls prey to a selection bias.
  • basketball is no streakier than a coin toss. For a 50 percent shooter, for example, the odds of making a basket are supposed to be no better after a hit — still 50-50. But in a purely random situation, according to the new analysis, a hit would be expected to be followed by another hit less than half the time. Finding 50 percent would actually be evidence in favor of the hot hand
  • Dr. Gilovich is withholding judgment. “The larger the sample of data for a given player, the less of an issue this is,” he wrote in an email. “Because our samples were fairly large, I don’t believe this changes the original conclusions about the hot hand. ”
  • Take a fair coin — one as likely to land on heads as tails — and flip it four times. How often was heads followed by another head?
  • For all their care to be objective, scientists are as prone as anyone to valuing data that support their hypothesis over those that contradict it. Sometimes this results in experiments that succeed only under very refined conditions, in certain labs with special reagents and performed by a scientist with a hot hand.
  • We’re all in the same boat. We evolved with this uncanny ability to find patterns. The difficulty lies in separating what really exists from what is only in our minds.

This Sociological Theory Explains Why Wall Street Is Rigged for Crisis - Bill Davidow -... - 0 views

  • near brush with nuclear catastrophe, brought on by a single foraging bear, is an example of what sociologist Charles Perrow calls a “normal accident.” These frightening incidents are “normal” not because they happen often, but because they are almost certain to occur in any tightly connected complex system.
  • Perrow had a fairly simple solution for the problem. High-risk systems, such as nuclear power plants, should be built only as a last resort.
  • errow stresses the role that human error and mismanagement play in these scenarios. The important lesson: failures in complex systems are caused not only by the hardware and software problems but by people and their motivations.
  • ...4 more annotations...
  • Normal accidents, like these, occur because two or more independent failures happen and interact in unpredictable ways. After studying calamities such as the Three Mile Island meltdown, explosions at chemical plants, and ships colliding in the open sea, Perrow observed that safety mechanisms put in place to make the systems safer in fact frequently trigger the final failure.
  • That solution won’t work for financial markets. We need currency hedges, futures markets, and derivatives to keep our economic systems functioning. But we also have to realize tweaking the current system will not fix the problem. Most of the supposedly strong cures implemented by legislators to date, such as prohibiting bank holding companies from proprietary trading, are inadequate as well.
  • how do we make our markets less danger prone? A good place to start would be to reduce the excessive trading volumes that lie at the root of accidents like the Flash Freeze, Flash Cash, and Goldman debacle. There is no valid reason for high frequency trading to make up more than 50 percent of all stock trades, and there is no pressing need for some $4 trillion in daily foreign currency transactions. A Tobin tax on transactions, first suggested by Noble laureate James Tobin in 1972, of as little as 0.1 percent, would significantly reduce these volumes. Smaller transaction volumes would reduce the size of accidents and possibly their frequency.
  • But tinkering with the current system and looking for easy ways out, as we are now, is bound to fail. We’re in danger of letting normal accidents in the financial system become all too normal.

Snakes on a Visual Plane | The Scientist Magazine® - 0 views

  • primates have a remarkable ability to detect snakes, even in a chaotic visual environment.

  • recorded pulvinar neuronal activity via electrodes implanted into the brains of two adult macaques—one male, one female—as they were shown images of monkey faces, monkey hands, geometric shapes, and snakes. The brains of both monkeys—which were raised at a national monkey farm in Amami Island, Japan, and had no known encounters with snakes before the experiment—showed preferential activity of neurons in the medial and dorsolateral pulvinar to images of snakes, as compared with the other stimuli. Further, snakes elicited the fastest and strongest responses from these neurons.

Social Connection Makes a Better Brain - Emily Esfahani Smith - The Atlantic - 0 views

  • Recent trends show that people increasingly value material goods over relationships—but neuroscience and evolution say this goes against our nature.
  • Do you prioritize your career or your relationships?
  • “Man is by nature a social animal … Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god.”

  • Just as human beings have a basic need for food and shelter, we also have a basic need to belong to a group and form relationships.
  • Lieberman sees the brain as the center of the social self. Its primary purpose is social thinking.
  • Every time we are not engaged in an active task—like when we take a break between two math problems—the brain falls into a neural configuration called the “default network.” When you have down time, even if it’s just for a second, this brain system comes on automatically.
  • “The default network directs us to think about other people’s minds—their thoughts, feelings, and goals.”
  • “Evolution has made a bet,” Lieberman tells me, “that the best thing for our brain to do in any spare moment is to get ready for what comes next in social terms.”
  • When economists put a price tag on our relationships, we get a concrete sense of just how valuable our social connections are—and how devastating it is when they are broken.
  • If you have a friend that you see on most days, it’s like earning $100,000 more each year.
  • To the brain, social pain feels a lot like physical pain—a broken heart can feel like a broken leg, as Lieberman puts it in his book.
  • But over the last fifty years, while society has been growing more and more prosperous and individualistic, our social connections have been dissolving.
  • Over the same period of time that social isolation has increased, our levels of happiness have gone down, while rates of suicide and depression have multiplied. 
  • Across the board, people are increasingly sacrificing their personal relationships for the pursuit of wealth.

Do Our Bones Influence Our Minds? : The New Yorker - 0 views

  • But their skeletons appeared essentially normal, he says, a result that left him “deeply depressed.”
  • It turns out that osteocalcin is a messenger, sent by bone to regulate crucial processes all over the body.
  • The finding represents new ground in how researchers view the skeleton: not only do bones provide structural support and serve as a repository for calcium and phosphate, they issue commands to far-flung cells
  • ...8 more annotations...
  • “This is a biggie,” said Eric Kandel, the neuroscientist and Nobel Laureate. “Who thinks of the bone as being an endocrine organ? You think of the adrenal gland, you think of the pituitary, you don’t think of bone.”
  • he most recent finding concerns the skeleton and the brain.
  • Karsenty showed that bone plays a direct role in memory and mood. Mice whose skeletons did not produce osteocalcin as a result of genetic manipulation were anxious, depressed, and almost completely unable to master a test of spatial memory. When Karsenty infused them with the missing hormone, however, their moods improved and their performance on the memory test became nearly normal. He also found that, in pregnant mice, osteocalcin from the mother’s bones crossed the placenta and helped shape the development of the fetus’s brain. In other words, bones talk to neurons even before birth.
  • As we age, our bone mass decreases. Memory loss, anxiety, and depression also become more common. These may be separate, unfortunate facts about getting old, but they could also be related.
  • Even more fantastically: Would it ever be possible to protect memory or treat age-related cognitive decline with a skeletal hormone? These are the kinds of questions that can spur either false hopes or imaginative leaps.
  • “I don’t know of any hormone that functions in mice but not to some extent in humans,” Thomas Clemens, of Johns Hopkins, told me in 2011
  • ne tantalizing hint comes from men who are unable to respond to the hormone as a result of a genetic mutation
  • Karsenty also believes that we know enough now to recognize that the body is far more networked and interconnected than most people think. “No organ is an island,” he likes to say.

A Curious Midlife Crisis for a Tech Entrepreneur - The New York Times - 0 views

  • as he approached 40, Fabrice Grinda, a French technology entrepreneur with an estimated net worth of $100 million, couldn’t shake the feeling that something was terribly wrong. Somehow the trappings of his success were weighing him down.
  • “People turn 40 and usually buy a shiny sports car,” Mr. Grinda said during an interview in a penthouse suite at Sixty LES, a downtown boutique hotel. “They don’t say, ‘I’m downsizing my life and giving up all my possessions to focus on experiences and friendships.’
  • He dubbed it “the very big downgrade”: He was going to travel the world, working on the fly while staying with friends and family. He was purposely arranging things so that he would have a chance to focus on what was meaningful in life.
  • ...13 more annotations...
  • But that is exactly what Mr. Grinda did. He moved out of the Bedford house in December 2012, ditched the city apartment and got rid of the McLaren. He donated clothes, sports equipment and kitchen utensils to the Church of St. Francis Xavier in Lower Manhattan. He gave his furniture to Housing Works and he packed a Tumi carry-on suitcase with 50 items, including two pairs of jeans, a bathing suit and 10 pairs of socks.
  • Once he realized his days as a roving houseguest were numbered, Mr. Grinda decided to shift his approach: He kept traveling, but now he was renting apartments on Airbnb or staying in luxury hotels.
  • Born in suburban Paris in 1974, Mr. Grinda graduated from Princeton in 1996 with a degree in economics. He worked as a consultant at McKinsey & Company for two years before moving back to France to found an online auction start-up funded by the business magnate Bernard Arnault, which Mr. Grinda sold in 2000.He returned to the United States, where he co-founded Zingy, a mobile phone ringtone and game maker, which fetched $80 million in a 2004 sale. After that, he was a founder of OLX, a Craigslist-like service that has become one of the largest global classified websites.Now he is an entrepreneur and angel investor, with more than 200 investments to date, who visits start-ups in Berlin, Paris, New York, San Francisco and other cities.
  • He looks (and acts) something like Sheldon Cooper, the oddball science geek played by Jim Parsons on “The Big Bang Theory,” an observation Mr. Grinda himself has made.“Friends, who knew me in my late teens and early twenties, would tell you I had exactly the same delusional sense of self-worth and condescending and arrogant self-centered worldview,” he wrote in a blog post that noted his similarities to the sitcom character.
  • In all, Mr. Grinda said, he stayed with about 15 friends and family members in the first months of 2013. “Everyone was, like, ‘It’s a great idea. Come over,’ ” Mr. Grinda said. “The problem is, the idea of ‘Great, come over’ and me there 24 hours a day, seven days a week, is very different. Especially when their lives are not in sync with mine.”
  • “When I looked back at the things that mattered the most to me,” he said, “they were experiences, friendships and family — none of which I had invested much in, partly because I was too busy, and partly because I felt anchored by my possessions.”
  • He hatched a new plan: His friends and family members would come to him.“Rather than me going to them and disrupting their routine,” he said, “getting everyone together in a setting of vacation makes more sense.”
  • He invited his parents, his friends, their partners, children and nannies for a two-week stay in Anguilla, an island east of Puerto Rico, where he rented two conjoining houses, at a cost of $240,000, with chefs and full house service (and a total of 19 bedrooms).
  • Mr. Grinda forgot to consider that not everyone lives as he does.For one thing, he had scheduled the Anguilla vacation during the school year, which meant friends with children couldn’t make it. The island’s remoteness, furthermore, meant some guests were forced to endure a tangle of flight connections, leaving some of them exhausted by the time they arrived.And many of the people he invited, who had jobs and other obligations, could stay only for a long weekend.
  • Mr. Grinda said he has learned a lot from his very big downgrade. He reconnected with old friends, even if it meant annoying them a little, and he rekindled his relationship with his father.“We spent time talking about his life,” he said. And he is no longer against the idea of having a fixed address; he said he is now in negotiations to buy a two-bedroom apartment on the Lower East Side, which he plans to rent out when he is not in town.
  • Still, the experiment has taken its toll. “The philosophy is interesting,” he said. “But how do you put it into practice? How do you make it real?”
  • He recently split up with Otilia Aionesei, a former model who works at technology start-up, whom he had been dating, off and on, for two years. The sticking point was their lack of a shared home.“If you want to be his girlfriend, this is the life you have to lead,” Ms. Aionesei said. “I like simple things, to watch movies on the same couch.”Mr. Grinda had a different view. “We went to the Galápagos,” he said. “We went to Tulum. To St. Barts. We have these wonderful experiences and memories together.”
  • “My home is where I am,” he said. “And it doesn’t matter if it is a friend’s place or a couch or the middle of the jungle or a hotel room on the Lower East Side. But I realize that most of humanity, especially women, don’t see it that way.”

No Consolation For Kalashnikov | Issue 59 | Philosophy Now - 0 views

  • The legendary AK 47 assault rifle was invented in 1946 by Mikhail Kalashnikov. It was issued to the armies of the old Warsaw Pact countries and has been used in many conflicts, eg by the North Vietnamese Army (NVA), Soviet soldiers in Afghanistan, and even this year by Al Qaeda operatives in Iraq.
  • Whatever interpretation one puts on those two conflicts, almost no-one sane would condone the use of the AK 47 in killing civilians, for instance Shiites in Iraq.
  • Mikhail Kalashnikov has come to have some doubts about his invention. He told The Times in June 2006, “I don’t worry when my guns are used for national liberation or defence. But when I see how peaceful people are killed and wounded by these weapons, I get very distressed and upset. I calm down by telling myself that I invented this gun 60 years ago to protect the interests of my country.”
  • ...10 more annotations...
  • Weapons research produces in the first place not guns, bombs, bullets and planes and the various command, control and communications hardware and software needed to use these things, but plans, blueprints and designs – knowledge and know-how. Unless these useful plans are lost or destroyed, they can be implemented or instantiated many times over, and thus project unforeseen into the future.
  • If any one person invented the atomic bomb, it was Leo Szilard. It seems he had the idea, and he made great efforts from 1935 until 1942, when the Manhattan Project was set up, to get the research done that would show whether an atomic bomb was possible; how to make one; and if need be, to provide the basis for actually making one.
  • This perception was greatly strengthened when Hahn and Strassmann discovered nuclear fission in Berlin in 1938. So Szilard, worried about the Nazis getting an atomic bomb, thought that the Allies should do the research to see if and how one could be made, in order to deter or otherwise prevent the Nazis from using one.
  • One way out of the dilemma is to refuse to do war research under any circumstances. I’d like to endorse this option, especially as it does not imply that we should judge Kalashnikov, Szilard, Watson-Watt and other well-intentioned researchers harshly, since we can argue that the dilemma has only become evident recently.
  • The point of this example is to show how scientists lose control of their work when they take part in weapons research – they lose control of it in other settings besides, but this case is the most problematic.
  • As far as Szilard and a good number of other atomic scientists were concerned there was no longer a rationale for the bomb project. Szilard, Philip Franck and others wrote The Franck Report in June 1945, which among other things advocated a demonstration of the power of the atomic bomb by dropping one on an uninhabited island. The Franck Report was ignored.The project was not abandoned, of course, and two of its products were used on Japanese cities, to kill mostly Japanese civilians.
  • Another possibility is to deny that weapons research must take place within history, as a good Marxist might put it. That is, as I would put it: Perhaps weapons research is not an activity that must take account of historical contingencies.
  • We must acknowledge that there is no such thing as an inherently defensive weapon, something that can only be used for the morally acceptable purpose of responding against an aggressor. Doing weapons research for defensive systems is therefore not morally acceptable, as any weapons might feasibly be used as part of an unjust war of aggression.
  • Kalashnikov’s preferred description of what he did when he designed the AK 47 is something like “providing the means for liberation,” or “defending my country,” not “providing the means to kill innocents.” However, he acknowledges that the latter description applies to his situation equally well. Nevertheless, J might try to portray her actions as something like “provide the means for deterrence,” the idea being that what she is helping to create is intended to deter, and hence prevent harm rather than cause it.
  • You might say that this is utopian, and it would never work, but then it might console Kalashnikov, who, after all, was a Marxist, and perhaps also a utopian.

Scientists identify vast underground ecosystem containing billions of micro-organisms |... - 0 views

  • Despite extreme heat, no light, minuscule nutrition and intense pressure, scientists estimate this subterranean biosphere is teeming with between 15bn and 23bn tonnes of micro-organisms, hundreds of times the combined weight of every human on the planet.
  • Researchers at the Deep Carbon Observatory say the diversity of underworld species bears comparison to the Amazon or the Galápagos Islands, but unlike those places the environment is still largely pristine because people have yet to probe most of the subsurface.

  • The team combines 1,200 scientists from 52 countries in disciplines ranging from geology and microbiology to chemistry and physics.
  • The results suggest 70% of Earth’s bacteria and archaea exist in the subsurface
  • “The strangest thing for me is that some organisms can exist for millennia. They are metabolically active but in stasis, with less energy than we thought possible of supporting life.”
  • Some microorganisms have been alive for thousands of years, barely moving except with shifts in the tectonic plates, earthquakes or eruption
  • these organisms are part of slow, persistent cycles on geological timescales.”
  • Underworld biospheres vary depending on geology and geography. Their combined size is estimated to be more than 2bn cubic kilometres, but this could be expanded further in the future
  • The researchers said their discoveries were made possible by two technical advances: drills that can penetrate far deeper below the Earth’s crust, and improvements in microscopes that allow life to be detected at increasingly minute levels.
  • The scientists have been trying to find a lower limit beyond which life cannot exist, but the deeper they dig the more life they find. There is a temperature maximum – currently 122C – but the researchers believe this record will be broken if they keep exploring and developing more sophisticated instruments.
  • Robert Hazen, a mineralogist at the Carnegie Institution for Science, said: “We must ask ourselves: if life on Earth can be this different from what experience has led us to expect, then what strangeness might await as we probe for life on other worlds?”

  • Some soldiers married Asian women and brought them home as war brides, while others primarily viewed Asian women as sexual objects. Both approaches perpetuated stereotypes of Asian women as sexually submissive, either as ideal wives or sexually exotic prostitutes.
  • In online digital pornography, Asian women are disproportionately presented as victims of rape, compared to white women or women of other racial backgrounds.
  • Harmful stereotypes of Asian women in American popular culture date back to at least the 19th century. Back then, American missionaries and military personnel in Asia viewed the women they met there as exotic and submissive.
  • The most recent high-profile example of this dynamic is the 2015 rape of a woman by white Stanford student Brock Turner. Not until 2019 did the woman, Chanel Miller, reveal her name and identity as an Asian American woman.
  • In March 2020, Asian American and Pacific Islander community organizations joined with San Francisco State University’s Asian American Studies Program to document incidents of anti-Asian racism occurring across the country during the COVID-19 pandemic.
  • The group has found that Asian women report hate incidents 2.3 times as often as Asian men.
  • Asian women are not the only targets of racial and sexual violence. Any non-white woman has a greater risk of these perils than white women do.

  • The 1619 Project introduced a date, previously obscure to most Americans, that ought always to have been thought of as seminal — and probably now will. It offered fresh reminders of the extent to which Black freedom was a victory gained by courageous Black Americans, and not just a gift obtained from benevolent whites.
  • in a point missed by many of the 1619 Project’s critics, it does not reject American values. As Nikole Hannah-Jones, its creator and leading voice, concluded in her essay for the project, “I wish, now, that I could go back to the younger me and tell her that her people’s ancestry started here, on these lands, and to boldly, proudly, draw the stars and those stripes of the American flag.” It’s an unabashedly patriotic thought.
  • ambition can be double-edged. Journalists are, most often, in the business of writing the first rough draft of history, not trying to have the last word on it. We are best when we try to tell truths with a lowercase t, following evidence in directions unseen, not the capital-T truth of a pre-established narrative in which inconvenient facts get discarded

  • on these points — and for all of its virtues, buzz, spinoffs and a Pulitzer Prize — the 1619 Project has failed.
  • That doesn’t mean that the project seeks to erase the Declaration of Independence from history. But it does mean that it seeks to dethrone the Fourth of July by treating American history as a story of Black struggle against white supremacy — of which the Declaration is, for all of its high-flown rhetoric, supposed to be merely a part.
  • he deleted assertions went to the core of the project’s most controversial goal, “to reframe American history by considering what it would mean to regard 1619 as our nation’s birth year.”
  • She then challenged me to find any instance in which the project stated that “using 1776 as our country’s birth date is wrong,” that it “should not be taught to schoolchildren,” and that the only one “that should be taught” was 1619. “Good luck unearthing any of us arguing that,” she added.
  • I emailed her to ask if she could point to any instances before this controversy in which she had acknowledged that her claims about 1619 as “our true founding” had been merely metaphorical. Her answer was that the idea of treating the 1619 date metaphorically should have been so obvious that it went without saying.
  • “1619. It is not a year that most Americans know as a notable date in our country’s history. Those who do are at most a tiny fraction of those who can tell you that 1776 is the year of our nation’s birth. What if, however, we were to tell you that this fact, which is taught in our schools and unanimously celebrated every Fourth of July, is wrong, and that the country’s true birth date, the moment that its defining contradictions first came into the world, was in late August of 1619?”
  • Here is an excerpt from the introductory essay to the project by The New York Times Magazine’s editor, Jake Silverstein, as it appeared in print in August 2019 (italics added):
  • In his introduction, Silverstein argues that America’s “defining contradictions” were born in August 1619, when a ship carrying 20 to 30 enslaved Africans from what is present-day Angola arrived in Point Comfort, in the English colony of Virginia. And the title page of Hannah-Jones’s essay for the project insists that “our founding ideals of liberty and equality were false when they were written.”
  • What was surprising was that in 1776 a politically formidable “defining contradiction” — “that all men are created equal” — came into existence through the Declaration of Independence. As Abraham Lincoln wrote in 1859, that foundational document would forever serve as a “rebuke and stumbling block to the very harbingers of reappearing tyranny and oppression.”
  • As for the notion that the Declaration’s principles were “false” in 1776, ideals aren’t false merely because they are unrealized, much less because many of the men who championed them, and the nation they created, hypocritically failed to live up to them.
  • These two flaws led to a third, conceptual, error. “Out of slavery — and the anti-Black racism it required — grew nearly everything that has truly made America exceptional,” writes Silverstein.
  • Nearly everything? What about, say, the ideas contained by the First Amendment? Or the spirit of openness that brought millions of immigrants through places like Ellis Island? Or the enlightened worldview of the Marshall Plan and the Berlin airlift? Or the spirit of scientific genius and discovery exemplified by the polio vaccine and the moon landing?
  • On the opposite side of the moral ledger, to what extent does anti-Black racism figure in American disgraces such as the brutalization of Native Americans, the Chinese Exclusion Act or the internment of Japanese-Americans in World War II?
  • The world is complex. So are people and their motives. The job of journalism is to take account of that complexity, not simplify it out of existence through the adoption of some ideological orthodoxy.
  • This mistake goes far to explain the 1619 Project’s subsequent scholarly and journalistic entanglements. It should have been enough to make strong yet nuanced claims about the role of slavery and racism in American history. Instead, it issued categorical and totalizing assertions that are difficult to defend on close examination.
  • It should have been enough for the project to serve as curator for a range of erudite and interesting voices, with ample room for contrary takes. Instead, virtually every writer in the project seems to sing from the same song sheet, alienating other potential supporters of the project and polarizing national debate.
  • James McPherson, the Pulitzer Prize-winning author of “Battle Cry of Freedom” and a past president of the American Historical Association. He was withering: “Almost from the outset,” McPherson told the World Socialist Web Site, “I was disturbed by what seemed like a very unbalanced, one-sided account, which lacked context and perspective.”
  • In particular, McPherson objected to Hannah-Jones’s suggestion that the struggle against slavery and racism and for civil rights and democracy was, if not exclusively then mostly, a Black one. As she wrote in her essay: “The truth is that as much democracy as this nation has today, it has been borne on the backs of Black resistance.”
  • McPherson demurs: “From the Quakers in the 18th century, on through the abolitionists in the antebellum, to the Radical Republicans in the Civil War and Reconstruction, to the N.A.A.C.P., which was an interracial organization founded in 1909, down through the civil rights movements of the 1950s and 1960s, there have been a lot of whites who have fought against slavery and racial discrimination, and against racism,” he said. “And that’s what’s missing from this perspective.”
  • Wilentz’s catalog of the project’s mistakes is extensive. Hannah-Jones’s essay claimed that by 1776 Britain was “deeply conflicted” over its role in slavery. But despite the landmark Somerset v. Stewart court ruling in 1772, which held that slavery was not supported by English common law, it remained deeply embedded in the practices of the British Empire. The essay claimed that, among Londoners, “there were growing calls to abolish the slave trade” by 1776. But the movement to abolish the British slave trade only began about a decade later — inspired, in part, Wilentz notes, by American antislavery agitation that had started in the 1760s and 1770s.
  • ie M. Harris, an expert on pre-Civil War African-American life and slavery. “On Aug. 19 of last year,” Harris wrote, “I listened in stunned silence as Nikole Hannah-Jones … repeated an idea that I had vigorously argued against with her fact checker: that the patriots fought the American Revolution in large part to preserve slavery in North America.”
  • The larger problem is that The Times’s editors, however much background reading they might have done, are not in a position to adjudicate historical disputes. That should have been an additional reason for the 1619 Project to seek input from, and include contributions by, an intellectually diverse range of scholarly voices. Yet not only does the project choose a side, it also brooks no doubt.
  • “It is finally time to tell our story truthfully,” the magazine declares on its 1619 cover page. Finally? Truthfully? Is The Times suggesting that distinguished historians, like the ones who have seriously disputed aspects of the project, had previously been telling half-truths or falsehoods?
  • unlike other dates, 1776 uniquely marries letter and spirit, politics and principle: The declaration that something new is born, combined with the expression of an ideal that — because we continue to believe in it even as we struggle to live up to it — binds us to the date.
  • On the other, the 1619 Project has become, partly by its design and partly because of avoidable mistakes, a focal point of the kind of intense national debate that columnists are supposed to cover, and that is being widely written about outside The Times. To avoid writing about it on account of the first scruple is to be derelict in our responsibility toward the second.

With Child Hunger Rising, A Federal Aid Program Has Stalled : NPR - 0 views

  • When schools shut down in the spring, that raised immediate worries about the nearly 30 million children who depend on school food.
  • According to a report from Feeding America, 1 in 4 households with children experienced food insecurity in 2020.
  • when families are having trouble stretching their food budget, the adults will go without food before allowing the children to go hungry. But in April, with shutdowns at their most acute, nearly 20 percent of mothers said their children themselves didn't have enough to eat.

  • School food programs have been working hard: offering groceries, pre-prepared meals and everything in between. But as we've reported, it often isn't enough.
  • Congress passed a law giving families the cash value of the meals they missed when schools were closed.
  • Families were eligible for $117 per child per month.
  • The potential value, estimates Bauer: $12 billion.
  • The U.S. Department of Agriculture didn't issue guidance to states on plans for how to do this for six weeks
  • So far, they have approved only the plans from Massachusetts, Indiana and Rhode Island. And they haven't yet touched the issue of how to give out the money to children under 6.
  • "The long and short of it is for the past three-plus months, states should have been able to distribute more than $100 of food benefits per child [per month]," she says. "And USDA is not making it easy for any state to roll out this program."
