A Real 'Very Stable Genius' Doesn't Call Himself One - The Atlantic - 2 views

  • During a brief stint of actually working at a tech company, I learned that some of the engineers and coders were viewed as just operating on a different plane: The code they wrote was better, tighter, and more elegant than other people’s, and they could write it much more quickly.
  • If you report long enough on politics and public life, even there you will see examples of exceptional strategic, analytic, and bargaining intelligence, along with a lot of clownishness.
  • They know what they don’t know. This to me is the most consistent marker of real intelligence. The more acute someone’s ability to perceive and assess, the more likely that person is to recognize his or her limits. These include the unevenness of any one person’s talents; the specific areas of weakness—social awkwardness, musical tin ear, being stronger with numbers than with words, or vice versa; and the incomparable vastness of what any individual person can never know. To read books seriously is to be staggered by the knowledge of how many more books will remain beyond your ken. It’s like looking up at the star-filled sky.

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

  • In a way, it’s startling how universal sleep is: In the midst of the hurried scramble for survival, across eons of bloodshed and death and flight, uncountable millions of living things have laid themselves down for a nice, long bout of unconsciousness. This hardly seems conducive to living to fight another day.
  • such a risky habit is so common, and so persistent, suggests that whatever is happening is of the utmost importance. Whatever sleep gives to the sleeper is worth tempting death over and over again, for a lifetime.
  • “What is so important that you risk being eaten, not eating yourself, procreation ... for this?”

  • Biologists call this need “sleep pressure”: Stay up too late, build up sleep pressure. Feeling drowsy in the evenings? Of course you are—by being awake all day, you’ve been generating sleep pressure! But like “dark matter,” this is a name for something whose nature we do not yet understand.
  • The search for the hypnotoxin was not unsuccessful. There are a handful of substances clearly demonstrated to cause sleep—including a molecule called adenosine, which appears to build up in certain parts of the brains of waking rats, then drain away during slumber. Adenosine is particularly interesting because it is adenosine receptors that caffeine seems to work on.
  • For instance, if adenosine puts us under at the moment of transition from wakefulness to sleep, where does it come from? “Nobody knows,” remarks Michael Lazarus, a researcher at the institute who studies adenosine. Some people say it’s coming from neurons, some say it’s another class of brain cells. But there isn’t a consensus. At any rate, “this isn’t about storage,” says Yanagisawa. In other words, these substances themselves don’t seem to store information about sleep pressure. They are just a response to it.
  • A few years ago, the group discovered a mouse that just could not seem to get rid of its sleep pressure. Its EEGs suggested it lived a life of snoozy exhaustion, and mice that had been engineered to carry its mutation showed the same symptoms. “This mutant has more high-amplitude sleep waves than normal. It’s always sleep-deprived,” says Yanagisawa. The mutation was in a gene called SIK3. The longer the mutants stay awake, the more chemical tags the SIK3 protein accumulates. The researchers published their discovery of the SIK3 mutants, as well as another sleep mutant, in Nature in 2016.

The Brutal Math of Gender Inequality in Hollywood - The Atlantic - 0 views

  • Lady Bird won the award for Best Motion Picture Musical or Comedy, but its writer and director Greta Gerwig was curiously not nominated for Best Director. That category’s five nominees were all male. In fact, only one woman has ever won a Golden Globe for directing: Barbra Streisand, in 1984, for Yentl. At the time, Gerwig was six months old, and her film’s lead actress had not yet been born. Hollywood remains an industry where women are more likely to be celebrated for speaking out in front of a camera than for holding one.
  • Finally, actresses are vulnerable, not only because men dominate powerful occupations, but also because women are cast to portray the very quality of vulnerability
  • Altogether, these surveys and studies suggest something quite simple: The ratio of women in an industry (like film) or in an occupation within that industry (like directing) shapes how women are treated. While more than 80 percent of women say they have been harassed at work, they are 50 percent more likely to say so in male-dominated industries.

A New Geo-Engineering Scheme to Prevent Catastrophic Sea-Level Rise - The Atlantic - 0 views

  • PRINCETON, N.J.—Geo-engineering, its most enthusiastic advocates will tell you, isn’t only possible. It’s already happening.
  • We know, they say, because we’re doing it—we just call it global warming. As humanity dumps billions of tons of greenhouse gases into the atmosphere every year, we’ve engineered a different climate system: one that is hotter, wetter, and more unwieldy than what people have lived in since the dawn of agriculture.
  • Researchers speculate that planes could periodically spray a clear gas into the high atmosphere that would prevent some sunlight from reaching Earth’s surface, cooling the globe in turn.

  • “At the same time I think he’s one of the very few people who’s said, okay, is there something we can do to slow how [ice] is going to change and how it will flow in the future?” she said. “This is kind of high-risk for young scientists, because everybody wants you to do what everyone else is doing. But somebody has to take those first steps.”

How It Became Normal to Ignore Texts and Emails - The Atlantic - 0 views

  • People don’t need fancy technology to ignore each other, of course: It takes just as little effort to avoid responding to a letter, or a voicemail, or not to answer the door when the Girl Scouts come knocking. As Naomi Baron, a linguist at American University who studies language and technology, puts it, “We’ve dissed people in lots of formats before.” But what’s different now, she says, is that “media that are in principle asynchronous increasingly function as if they are synchronous.”
  • The result is the sense that everyone could get back to you immediately, if they wanted to—and the anxiety that follows when they don’t. But the paradox of this age of communication is that this anxiety is the price of convenience. People are happy to make the trade to gain the ability to respond whenever they feel like it.
  • It’s anxiety-inducing because written communication is now designed to mimic conversation—but only when it comes to timing. It allows for a fast back-and-forth dialogue, but without any of the additional context of body language, facial expression, and intonation. It’s harder, for example, to tell that someone found your word choice off-putting, and thus to correct it in real-time, or try to explain yourself better. When someone’s in front of you, “you do get to see the shadow of your words across someone else’s face,” Turkle says.
  • ...2 more annotations...
  • But just because people know how stressful it can be to wait for a reply to what they thought would be an instant message doesn’t mean they won’t ignore others’ messages in turn.
  • Still, even though instant written communication can be overwhelming and anxiety-inducing, people prefer it. Americans spend more time texting than talking on the phone, and texting is the most frequent form of communication for Americans under 50.

New Neuroscience Study Reveals What Worry About Money Does To Your Brain - 0 views

  • These findings suggest more evidence for why heuristics, or rules of thumb, are both so effective and ubiquitous. Consider a few from the financial world: Pay yourself first. Sell in May and go away. Buy and hold. Only use the principal. Buy low, sell high. The list could go on and on.
  • It’s no surprise that financial stress is draining. Anyone who’s worried over a budget or fretted about making the wrong investment choice or major purchase can recognize the telltale signs of such anxiety. But what’s actually happening to your brain when you feel under such pressure?
  • New research conducted by neuroscientist Sam Barnett, co-founder of ThinkAlike Laboratories and sponsored by Northwestern Mutual, offers a rare glimpse at the brain while it is making financial decisions—and finds that anxiety actually impairs our ability to make sound decisions.

  • Our brain was designed to make binary decisions—fight or flight—and avoid dangers,” Barnett says. But modern life with its ample choices and options doesn’t match how our brains naturally process information—explaining some ultimately self-defeating reactions such as impulsivity or inaction.

How To Use Neuroscience To Improve Your Career - 0 views

  • When someone says they aren’t a morning person, it may be closer to the truth than you think.  "Every person has their own brain profile," Cerf said. We each have a circadian rhythm, or an internal master clock that influences when we wake and sleep.
  • With the help of technology, sensors measuring brain activity can reveal how someone feels when they make choices. “We look at your diary for the entire week. We look at all the choices you made, and you try to tell me which ones you’re happy with and which ones you aren’t.” Then, Cerf compares those responses to brain activity to expose the truth.
  • A major influence on your productivity is sleep. Insomnia leads to the loss of 11.3 days’ worth of productivity each year on average, according to a Harvard research study. Your brain and your body need rest. This is why Cerf stressed that we should unplug entirely when we go on vacation. He even suggested changing your standard auto-reply for work emails to an auto-delete.

Why Asia Is Fast Becoming A Global Leader In Neuroscience - 0 views

  • The world is on the cusp of redefining brain aging. Asia Pacific, known for countries with rapidly aging populations, has unimaginable potential to lead the charge in research and innovation for better, younger, healthier brains.
  • The human brain contains approximately 80 billion neurons, has trillions of connections, is estimated to store up to 2.5 petabytes of memory, and for more than 3000 years we’ve asked questions about how it works.
  • One thing we have realized is that as exceptional as our brain is, the biological process of aging, also occurs in the brain.
  • ...2 more annotations...
  • Asian scientists, laboratories and companies are fast becoming a major driver for this innovation – perhaps not a surprise as we are already facing the challenges of an aging population such as growing economic, societal and personal costs.
  • It is an exciting time to be a neuroscientist and we are closer now than ever to developing breakthrough treatments and technologies that have the potential to make real societal impacts. Neuroscience has advanced more in the last 10 years than the previous 50, and with new perspectives starting to find a voice, I’m quite excited to see what the next 10 years will hold.

Neuroscience Is Making Significant Progress In Understanding Emotional Pain - 0 views

  • We are learning a lot right now about the neuroscience of emotions. Specifically, we are learning that there is a lot of overlap between the way we process physical pain and the way we process emotional pain.
  • Understanding emotional pain could be powerful in understanding a lot of the common emotional maladies that are regularly treated with psychotherapy or mood altering medications. Depression, anxiety, trauma, social pain, these are all debilitating disorders that are poorly understood and often poorly treated.
  • Humans are a unique species in two ways that account for our intense response to social rejection. We are born physically immature because of our enormous heads, and we require a lot of care early on. Because of our immaturity at birth, our species has selected for a deeply innate sense of bonding between individuals. The other unique feature of our species is that we require a lot of calories, probably also due to our oversized brains. Brains are calorie intensive organs and our brains are huge. So, humans burn about 400 more calories per day than other primates when you account for size [2]. Since we burn so much food, we as a species, have an innate drive to share food, which may have allowed us to get through bad hunting or gathering days in early human history. So, humans are naturally drawn to bond with others and to be conscious of aligning with a group of people where food sharing is possible.
  • ...3 more annotations...
  • It makes sense then, that losing a friend, or being rejected by a group might register to a person as a very dangerous thing. Emotional pain might result if a person discovers that they weren’t invited to a dinner party with friends.
  • One thing we do know is that people who have a lot of friends have high pain thresholds
  • Look for cutting edge neuroscience coming out in the next few years that helps us understand how to raise the social pain threshold. We could, very soon, have some practical answers for people with debilitating social anxiety, depression, and loneliness.

Outsmarting Our Primitive Responses to Fear - The New York Times - 0 views

  • fear drives much of human behavior. And it’s not just fear of physical harm that makes us want to hide under the covers. The twin fears of intimacy and rejection, for example, shape many of our social interactions.
  • Scientists say fear and its companion — the fight, flight or freeze response — can save us when faced with imminent physical harm.
  • It’s why you jump when you sense rustling in the bushes before realizing it’s just your neighbor’s cat. That reflex can save your life in certain circumstances such as leaping out of the way of an oncoming car. Trouble starts when you can’t tamp down your amygdala’s response, which makes you obsess and perhaps do counterproductive things when faced with concerning but not life-threatening events like the Equifax hack or a vulnerable social situation like asking someone out on a date.
  • ...5 more annotations...
  • Consciously activating the more measured, analytical part of your brain is the key to controlling runaway fear and anxiety.
  • But it’s not so easy in an era when social media and cable news make us aware of every actual or potential disaster occurring anywhere in the world (and in a repeating loop). It’s even more difficult if you have lots of stress or instability at home or work.
  • “Our culture valorizes strength and power and showing fear is considered weakness,” said Leon Hoffman, co-director of the Pacella Research Center at the New York Psychoanalytic Society & Institute in Manhattan. “But you are actually stronger if you can acknowledge fear.”
  • “The more you try to suppress fear, either by ignoring it or doing something else to displace it, the more you will actually experience it,” said Kristy Dalrymple, a clinical assistant professor of psychiatry and human behavior at Alpert Medical School of Brown University.
  • Psychologists and neuroscientists are also finding that the amygdala is less apt to freak out if you are reminded that you are loved or could be loved. For example, seeing images of people with frightened expressions is usually a huge trigger for the amygdala, but that response is greatly diminished when subjects are first shown pictures of people being cared for or hugged.

What if You Knew Alzheimer's Was Coming for You? - The New York Times - 0 views

  • When Ms. Gregory consulted with a neurologist about how to delay the onset of illness, he had four words for her: “Good luck with that.” After all, no drug had proven effective in reversing Alzheimer’s disease. And preventive measures like diet and exercise, the neurologist told her, would do no good.
  • So you may be faced with some difficult choices within the next decade: Do you want to receive potentially alarming news about your cognitive health, or would you rather not? If you learn that you have a high risk for Alzheimer’s, is that information you will want to keep private — from employers, clients, health insurers and others? Or will you want to openly embrace it as part of your identity and publicly advocate for a cure?
  • Jason Karlawish, a professor of medicine and neurology at the University of Pennsylvania, studies how people at high risk of Alzheimer’s disease cope with that knowledge. “We have to make it socially acceptable to talk about having risk of getting dementia,” he told me. “I think that is one of the ground zero struggles we are going to face in the coming decades.”

Exercise May Enhance the Effects of Brain Training - The New York Times - 0 views

  • Exercise broadly improves our memories and thinking skills, according to a wealth of science. The evidence supporting similar benefits from so-called brain training has been much iffier, however, with most people performing better only on the specific types of games or tasks practiced in the program.
  • Most of us are blissfully unaware of the complexity of our brain’s memory systems. Memories come in many different types, including detailed recollections of faces and objects and how they differ from similar faces and objects, as well as separate memories about where and when we last saw those things. These remembrances are created and stored throughout the hippocampus, our brain’s primary memory center.
  • In general, the young people who had exercised, whether they also brain trained or not, were then more physically fit than those in the control group. They also, for the most part, performed better on memory tests. And those improvements spanned different types of memory, including the ability to rapidly differentiate among pictures of objects that looked similar, a skill not practiced in the brain-training group.
  • ...3 more annotations...
  • These enhancements in memory were most striking among the volunteers whose fitness had also improved the most, especially if they also practiced brain training.
  • But the gains were not universal, the researchers found. Some of the young people in both exercise groups barely added to their aerobic fitness and also had the skimpiest improvements in memory.
  • And the effort does not need to be formal or complicated, she adds. “I would suggest memorizing the details of a painting or landscape” — or perhaps a loved one’s face — before or after each workout, she says. It could provide broader memory benefits all around.

How we determine who's to blame | MIT News - 0 views

  • This process can be conscious, as in the soccer example, or unconscious, so that we are not even aware we are doing it. Using technology that tracks eye movements, cognitive scientists at MIT have now obtained the first direct evidence that people unconsciously use counterfactual simulation to imagine how a situation could have played out differently.
  • “What’s really cool about eye tracking is it lets you see things that you’re not consciously aware of,” Tenenbaum says. “When psychologists and philosophers have proposed the idea of counterfactual simulation, they haven’t necessarily meant that you do this consciously. It’s something going on behind the surface, and eye tracking is able to reveal that.”
  • “It’s in the close cases where you see the most counterfactual looks. They’re using those looks to resolve the uncertainty,” Tenenbaum says.
  • ...1 more annotation...
  • “We think this process of counterfactual simulation is really pervasive,” Gerstenberg says. “In many cases it may not be supported by eye movements, because there are many kinds of abstract counterfactual thinking that we just do in our mind. But the billiard-ball collisions lead to a particular kind of counterfactual simulation where we can see it.”

How badly do you want something? Babies can tell | MIT News - 0 views

  • Babies as young as 10 months can assess how much someone values a particular goal by observing how hard they are willing to work to achieve it, according to a new study from MIT and Harvard University.
  • This ability requires integrating information about both the costs of obtaining a goal and the benefit gained by the person seeking it, suggesting that babies acquire very early an intuition about how people make decisions.
  • “This paper is not the first to suggest that idea, but its novelty is that it shows this is true in much younger babies than anyone has seen. These are preverbal babies, who themselves are not actively doing very much, yet they appear to understand other people’s actions in this sophisticated, quantitative way,”
  • ...4 more annotations...
  • “This study is an important step in trying to understand the roots of common-sense understanding of other people’s actions. It shows quite strikingly that in some sense, the basic math that is at the heart of how economists think about rational choice is very intuitive to babies who don’t know math, don’t speak, and can barely understand a few words
  • “Abstract, interrelated concepts like cost and value — concepts at the center both of our intuitive psychology and of utility theory in philosophy and economics — may originate in an early-emerging system by which infants understand other people's actions,” she says. 
  • In other words, they apply the well-known logic that all of us rely on when we try to assess someone’s preferences: The harder she tries to achieve something, the more valuable is the expected reward to her when she succeeds.”
  • “We have to recognize that we’re very far from building AI systems that have anything like the common sense even of a 10-month-old,” Tenenbaum says. “But if we can understand in engineering terms the intuitive theories that even these young infants seem to have, that hopefully would be the basis for building machines that have more human-like intelligence.

Andrew Anglin: The Making of an American Nazi - The Atlantic - 0 views

  • “You fucking wicked kike whore,” Andrew Auernheimer, The Daily Stormer’s webmaster, said in a voicemail for Gersh. “This is Trump’s America now.”
  • Over the next week, the Stormers besieged Whitefish businesses, human-rights groups, city-council members—anyone potentially connected to the targets. A single harasser called Judah’s office more than 500 times in three days, according to the Whitefish police. Gersh came home one night to find her husband sitting at home in the dark, suitcases on the floor, wondering whether they should flee. “I have never been so scared in my entire life,” she later told me.
  • That Anglin, a 33-year-old college dropout, could unleash such mayhem—Whitefish’s police chief, Bill Dial, likened it to “domestic terrorism”—was a sign of just how emboldened the alt-right had become.
  • ...9 more annotations...
  • Anglin is an ideological descendant of men such as George Lincoln Rockwell, who created the American Nazi Party in the late 1950s, and William Luther Pierce, who founded the National Alliance, a powerful white-nationalist group, in the 1970s. Anglin admires these predecessors, who saw themselves as revolutionaries at the vanguard of a movement to take back the country. He dreams of a violent insurrection.
  • Anglin has the internet. His reach is exponentially greater, his ability to connect with like-minded young men unprecedented.
  • Anglin and his ilk like to talk about the Overton Window, a term that describes the range of acceptable discourse in society.
  • They’d been tugging at that window for years only to watch, with surprise and delight, as it flew wide open during Donald Trump’s candidacy. Suddenly it was okay to talk about banning Muslims or to cast Mexican immigrants as criminals and parasites—which meant Anglin’s even-more-extreme views weren’t as far outside the mainstream as they once had been
  • Until the Roof massacre, Burkholder hadn’t thought about the “adorable,” “happy-go-lucky” boy in her class who loved dinosaurs. Anglin was a normal kid back then, whose only remarkable quality was his extraordinarily nasal voice—it was so bad that Burkholder thought he might have a sinus problem, and raised the issue with his mother, Katie, at a parent–teacher conference.
  • y all outward appearances, Andrew Anglin had an ordinary, comfortable childhood, at least until adolescence. He grew up in a big house in Worthington Hills, an upper-middle-class neighborhood, where he collected X-Men comics, played computer games, ate burgers at the original Wendy’s restaurant, and got into music with his best friend, West Emerson. And he loved to read. One book that left a deep impression on him was Weasel, which tells the story of a boy in frontier Ohio seeking revenge against a psychopath who, having run out of American Indians to murder, takes to slaughtering white homesteaders.
  • A declared atheist, he styled his reddish hair in dreadlocks and favored jeans with 50-inch leg openings. He often wore a hoodie with a large fuck racism patch on the back.
  • Anglin was one of only two vegans at Linworth
  • But people who knew Anglin in high school told me that, for reasons that were unclear, his behavior became erratic and frightening sometime around the beginning of his sophomore year at Linworth

How World War II Spurred a Veteran's Ambition - The Atlantic - 0 views

  • My first 18 months of military service were uninspiring. Donning the uniform did not fill me with pride, nor did the experience alter my perspective on life. What basic training had taught me was that the best way to get by was to stay out of sight.
  • Accordingly, my detachment expanded its mission: all males—soldiers and others of military serviceable age, no matter where encountered or whether in uniform—were to be taken prisoner unless they had persuasive evidence of either having been exempted or discharged from military service. Anyone without such proof was considered a potential guerilla. A sweep of the countryside would yield scores of German “civilians,” among them soldiers who had simply shed their uniform or party activists suspected of organizing a resistance usually with cover stories that I had to break. Not only did I become very adept at this task, but it also gave me some great insights into postwar German mentalities—insights that would later inspire me to revisit my views on higher education.
  • Wilke and his family had emigrated from Germany in the early 1920s, and he still spoke German with a genuine Saxon dialect.
  • ...4 more annotations...
  • As soon as I was released from the hospital, I worked my way step-by-step from France back to Berlin, the capital of the four occupying powers. After some stumbling blocks and a job I despised, I found a position as a research analyst in the intelligence branch of the military government’s information-control division.
  • This job turned out to be extremely challenging, but that also made it a real blessing. I wrote drafts on a wide range of political topics, including the identification of potential political leaders not yet recognized, a catalog of the rumors circulating among the population, incidents indicative of how people felt about American troops, and the dominant mood among German youth. We gleaned information from reports compiled by field representatives stationed in roughly a dozen communities throughout the American occupation zone, supplemented with details from German newspapers—and, in my case, with insights based on contacts and conversation I had whenever I passed myself off as a German civilian.
  • That is how my war and post-war service induced me, in the fall of 1947, after an interlude of more than five years, to enroll in the University of Chicago as a freshman. I stayed for six years, left with a Ph.D., and ever since enjoyed a long academic career as a sociologist, first specializing in the military and then studying propaganda and the effect of television on politics.
  • World War II spurred my ambition by teaching me how to navigate the army. Those lessons led me to confront the society I had once known so well, and to study politics and people living in a time of upheaval.

The neuroscience of inequality: does poverty show up in children's brains? | Inequality... - 0 views

  • The Neurocognition, Early Experience and Development Lab is home to cutting-edge research on how poverty affects young brains, and I’ve come here to learn how Noble and her colleagues could soon definitively prove that growing up poor can keep a child’s brain from developing.
  • handful of neuroscientists and pediatricians who’ve seen increasing evidence that poverty itself – and not factors like nutrition, language exposure, family stability, or prenatal issues, as previously thought – may diminish the growth of a child’s brain.
  • poor kids tended to perform worse academically than their better-off peers
  • ...5 more annotations...
  • Prior to their study, scientists had never investigated the specific cognitive tasks (face learning, picture learning, vocabulary tests) in which poor children underperformed, let alone mapped out how their brain structure and development might differ.
  • The results, which Noble and Farah reported in a 2005 paper, were the beginning of what they call a “neurocognitive profile” of socioeconomic status and the developing brain. Farah, Noble and other scientists soon began using magnetic resonance imaging (MRI) scans to examine the brains of children across the socioeconomic spectrum.
  • The results were striking. In one study, Farah looked at 283 MRIs and found that kids from poorer, less-educated families tended to have thinner subregions of the prefrontal cortex – a part of the brain strongly associated with executive functioning – than better-off kids. That could explain weaker academic achievement and even lower IQs.
  • What’s more, the data indicated that small increases in family income had a much larger impact on the brains of the poorest children than similar increases among wealthier children. And Noble’s data also suggested that when a family falls below a certain basic level of income, brain growth drops off precipitously. Children from families making less than $25,000 suffered the most, with 6% less brain surface area than peers in families making $150,000 or more.
  • It’s really a shame for this field that Hillary Clinton’s not our president Martha Farah These studies indicate it isn’t one specific factor that’s solely responsible for diminishing brain growth and intellectual potential, but rather the larger environment of poverty.

Ambitious neuroscience project to probe how the brain makes decisions | Science | The G... - 0 views

  • World-leading neuroscientists have launched an ambitious project to answer one of the greatest mysteries of all time: how the brain decides what to do.
  • If the researchers can unravel what happens in detail, it would mark a dramatic leap forward in scientists’ understanding of a process that lies at the heart of life, and which ultimately has implications for intelligence and free will.
  • Half of the IBL researchers will perform experiments and the other half will focus on theoretical models of how the brain makes up its mind.
  • ...2 more annotations...
  • The IBL hopes to overcome these flaws. Scientists on the project will work on exactly the same problems in precisely the same way. Animal experiments, for example, will use one strain of mouse, and all will be trained, tested and scored in the same way. It is an obvious strategy, but not a common one in science: in any lab, there is a constant urge to tweak experiments to make them better. “Ultimately, the reason it’s worth addressing is in the proverb: ‘alone we go fast, together we go far’,” said Churchland.
  • Decision-making is a field in itself, so IBL researchers will focus on simple, so-called perceptual decisions: those that involve responding to sights or sounds, for example. In one standard test, scientists will record how neurons fire in mice as they watch faint dots appear on a screen and spin a Lego wheel to indicate if the dots are on the left or the right. The mice make mistakes when the dots are faint, and it is these marginal calls that are most interesting to scientists.

A Beginner's Guide to Self-Awareness - 0 views

  • The vast majority of people — up to 95 percent, in fact — believe they have a decent amount of self-awareness. And maybe you’re one of the lucky 10 to 15 percent who really does have an accurate view of themselves — but if we’re going by the numbers, well, the odds aren’t in your favor.
  • On a good day, 80 percent of us are lying to ourselves about whether we’re lying to ourselves
  • Internal self-awareness is the ability to introspect and recognize your authentic self, whereas external self-awareness is the ability to recognize how you fit in with the rest of the world. “It’s almost like two different camera angles,” Eurich says.
  • ...5 more annotations...
  • The two are independent, entirely different variables, meaning you can have one without the other. For example, maybe you know someone who is a complete navel-gazer with a high level of internal self-awareness. Yet you and everyone else think this person is a selfish jerk, but because he never receives external feedback, he has no idea. Conversely, someone could have a high level of external self-awareness, a clear understanding of how they fit in with the rest of the world, without knowing what they want and what makes them happy. To be truly, fully self-aware, though, you need both components — a feat that’s difficult to pull off for pretty much anyone. But, it’s worth noting, not impossible.
  • Modern life makes it easy to become a part of what Eurich calls the “cult of self”: social media, for example, acts as a microphone-slash-spotlight we never have to turn off, while the concept of “personal branding” turns careful image curation into a professional skill.
  • In that last sentence, Kahneman is alluding to the “bias blind spot,” our tendency to recognize cognitive biases in others without noticing them in ourselves.
  • Without self-acceptance, self-awareness becomes an unpleasant process, which in turn keeps us from embracing it.
  • Your approach matters, too. When introspecting, it’s common for people to ask “why.” Why didn’t I get that promotion? Why do I keep fighting with my spouse? “Research has shown there are two problems with this,” Eurich said. “The question ‘why’ sucks us into an unproductive, paralyzed state. It gets us into this victim mentality.” Second, no matter how confident we are about the answer to “why,” we’re almost always wrong.
