  • Happiness is not how many things you do, but how well you do them.
  • When you regulate your daily actions, you deactivate your “fight or flight” instincts because you’re no longer confronting the unknown.
  • As children, routine gives us a feeling of safety. As adults, it gives us a feeling of purpose.
  • ou feel content because routine consistently reaffirms a decision you already made.
  • As your body self-regulates, routine becomes the pathway to “flow.”

  • I’ve realized how blind we are to the kinds of insights tech companies are gaining about us through our gadgets. Our blindness not only keeps us glued to privacy-invading tech
  • it also means that we’ve failed to create a political culture that is in any way up to the task of limiting surveillance.
  • few of our cultural or political institutions are even much trying to tamp down the surveillance state.
  • Yet the United States and other supposedly liberty-loving Western democracies have not ruled out such a future

  • Tracking technologies have become cheap and widely available — for less than $100, my colleagues were able to identify people walking by surveillance cameras in Bryant Park in Manhattan.

  • I can longer pretend I’ve got nothing to worry about. Sure, I’m not a criminal — but do I want anyone to learn everything about me?
  • more to the point: Is it wise for us to let any entity learn everything about everyone?
  • The remaining uncertainty about the surveillance state is not whether we will submit to it — only how readily and completely, and how thoroughly it will warp our society.
  • Will we allow the government and corporations unrestricted access to every bit of data we ever generate, or will we decide that some kinds of collections, like the encrypted data on your phone, should be forever off limits, even when a judge has issued a warrant for it?
  • In the future, will there be room for any true secret — will society allow any unrecorded thought or communication to evade detection and commercial analysis?
  • How completely will living under surveillance numb creativity and silence radical thought?
  • Can human agency survive the possibility that some companies will know more about all of us than any of us can ever know about ourselves?

One paragraph that puts the white-black life expectancy gap in (horrifying) context - Vox - 0 views

  • It is generally well-reported that there is a life expectancy gap between white and black Americans of about four years. But it can be hard to visualize exactly what this number means. In a recent conversation, David Williams, public health researcher at Harvard, described the racial gap to me in stark terms: One of the ways to think of the racial gap in health is to think of how many black people die prematurely every year who wouldn't die if there were no racial differences in health. The answer to that from a carefully done [2001] scientific study is 96,800 black people die prematurely every year. Divide it by 365 [days], that's 265 people dying prematurely every day. Imagine a jumbo jet — with 265 passengers and crew — crashing at Reagan Washington Airport today, and the same thing happening tomorrow and every day next week and every day next month. That's what we're talking about when we say there are racial disparities in health.
  • I asked Williams why there is such a tremendous gap in black and white life expectancy. He said there's no single issue to blame; it instead comes down to many factors, largely related to where people live.
  •  
    Again, this isn't just because of one single variable. It's a mix of issues, including how walkable a neighborhood is, how clean the air, water, and soil are, the availability of healthy foods, public health policies that push people away from bad habits or foods, and so on. Geographic location just reflects the place all those ideas come together - often in a way that affects certain groups more than others. And it shows why it's important to take a comprehensive view toward public health policy, tackling a variety of issues at once, instead of focusing solely on just one or two problems in a community.

Opinion | The Social Sciences' 'Physics Envy' - The New York Times - 0 views

  • Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,” “experiment,” “law”) evocative of physics and chemistry.
  • Many social scientists contend that science has a method, and if you want to be scientific, you should adopt it. The method requires you to devise a theoretical model, deduce a testable hypothesis from the model and then test the hypothesis against the world. If the hypothesis is confirmed, the theoretical model holds; if the hypothesis is not confirmed, the theoretical model does not hold. If your discipline does not operate by this method — known as hypothetico-deductivism — then in the minds of many, it’s not scientific.
  • it’s not even a good description of how the “hard” sciences work. It’s a high school textbook version of science, with everything messy and chaotic about scientific inquiry safely ignored.
  • ...9 more annotations...
  • For the sake of everyone who stands to gain from a better knowledge of politics, economics and society, the social sciences need to overcome their inferiority complex, reject hypothetico-deductivism and embrace the fact that they are mature disciplines with no need to emulate other sciences.
  • Or consider the famous “impossibility theorem,” developed by the economist Kenneth Arrow, which shows that no single voting system can simultaneously satisfy several important principles of fairness. There is no need to test this model with data — in fact, there is no way to test it — and yet the result offers policy makers a powerful lesson: there are unavoidable trade-offs in the design of voting systems.
  • Unfortunately, the belief that every theory must have its empirical support (and vice versa) now constrains the kinds of social science projects that are undertaken, alters the trajectory of academic careers and drives graduate training. Rather than attempt to imitate the hard sciences, social scientists would be better off doing what they do best: thinking deeply about what prompts human beings to behave the way they do.
  • theoretical models can be of great value even if they are never supported by empirical testing. In the 1950s, for instance, the economist Anthony Downs offered an elegant explanation for why rival political parties might adopt identical platforms during an election campaign. His model relied on the same strategic logic that explains why two competing gas stations or fast-food restaurants locate across the street from each other — if you don’t move to a central location but your opponent does, your opponent will nab those voters (customers). The best move is for competitors to mimic each other. This framework has proven useful to generations of political scientists even though Mr. Downs did not empirically test it and despite the fact that its main prediction, that candidates will take identical positions in elections, is clearly false. The model offered insight into why candidates move toward the center in competitive elections
  • Likewise, the analysis of empirical data can be valuable even in the absence of a grand theoretical model. Did the welfare reform championed by Bill Clinton in the 1990s reduce poverty? Are teenage employees adversely affected by increases in the minimum wage?
  • Answering such questions about the effects of public policies does not require sweeping theoretical claims, just careful attention to the data.
  • theories are like maps: the test of a map lies not in arbitrarily checking random points but in whether people find it useful to get somewhere.
  • Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,” “experiment,” “law”) evocative of physics and chemistry.

What Johannes Kepler Got Wrong - 0 views

  • ohannes Kepler was one of the leading characters in the history of astronomy. His most famous achievement was the three laws of planetary motion, still taught in courses today. However, like all other human beings, he was not perfect and made mistakes
  • Johannes Kepler was one of the most influential figures in the history of astronomy. His three laws of planetary movement changed the world of science significantly and became a foundation for other scientists to build theories upon.
  • Nonetheless, there are theories in his past that are not even close to reality.
  • ...10 more annotations...
  • In 1609, Kepler published a book containing the first two laws. The book also revealed his new model of the solar system, which was against what most scientists back then believed.
  • He stated that planets moved in elliptical orbits through the solar system, with the Sun located at one focus of the ellipse. Before Kepler, they believed that all orbits in the solar system were perfectly circular.
  • About ten years later, Kepler added his third law: that square of the orbital period divided by the cube of orbit’s semi-major axis is the same for all planets. Although not immediately accepted, his three laws took science to the next level. Why was he initially not appreciated?
  • Kepler applied this to the planets and stated that the solar system was built upon geometrical objects called Platonic solids that are a specific type of three-dimensional shape. They have identical sides or surfaces, edges of equal length, and angles of equal extent.
  • The model Kepler presented was based on a sequence of six spheres and the five Platonic solids, each located between two spheres. Back then, only six planets were discovered as Uranus and Neptune’s discovery took until the 18th and 19th centuries. Thus, each sphere represented one planet.
  • nitially, it seemed to explain the approximate ratios of the orbits of the six planets. It also gave a reason why there are only six planets—because there are only five Platonic shapes, each of which needs to fit between the orbit of two planets, only once
  • Kepler published this theory in detail, in his book Mysterium Cosmographicum. Despite all the value he gave to this theory, we now know how wrong it was.
  • Kepler cherished the theory as his most significant work, long after he had discovered the three laws.
  • However, the number of planets in the solar system or any other system in the universe is not predictable. Many of the numbers appearing everywhere are out of a mere accident, just like the number of planets.
  • Kepler thought his greatest achievement was the wrong solar system he drew, but it was the three laws that were so right to survive to date.

Human Brain: facts and information - 0 views

  • The human brain is more complex than any other known structure in the universe.
  • Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.
  • The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Animals such as elephants, dolphins, and whales actually have larger brains, but humans have the most developed cerebrum. It's packed to capacity inside our skulls, with deep folds that cleverly maximize the total surface area of the cortex.
  • ...18 more annotations...
  • The cerebrum has two halves, or hemispheres, that are further divided into four regions, or lobes. The frontal lobes, located behind the forehead, are involved with speech, thought, learning, emotion, and movement.
  • Behind them are the parietal lobes, which process sensory information such as touch, temperature, and pain.
  • At the rear of the brain are the occipital lobes, dealing with vision
  • Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.
  • The second-largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum.
  • diencephalon, located in the core of the brain. A complex of structures roughly the size of an apricot, its two major sections are the thalamus and hypothalamus
  • The brain is extremely sensitive and delicate, and so it requires maximum protection, which is provided by the hard bone of the skull and three tough membranes called meninges.
  • Want more proof that the brain is extraordinary? Look no further than the blood-brain barrier.
  • This led scientists to learn that the brain has an ingenious, protective layer. Called the blood-brain barrier, it’s made up of special, tightly bound cells that together function as a kind of semi-permeable gate throughout most of the organ. It keeps the brain environment safe and stable by preventing some toxins, pathogens, and other harmful substances from entering the brain through the bloodstream, while simultaneously allowing oxygen and vital nutrients to pass through.
  • One in five Americans suffers from some form of neurological damage, a wide-ranging list that includes stroke, epilepsy, and cerebral palsy, as well as dementia.
  • Alzheimer’s disease, which is characterized in part by a gradual progression of short-term memory loss, disorientation, and mood swings, is the most common cause of dementia. It is the sixth leading cause of death in the United States
  • 50 million people suffer from Alzheimer’s or some form of dementia. While there are a handful of drugs available to mitigate Alzheimer’s symptoms, there is no cure.
  • Unfortunately, negative attitudes toward people who suffer from mental illness are widespread. The stigma attached to mental illness can create feelings of shame, embarrassment, and rejection, causing many people to suffer in silence.
  • In the United States, where anxiety disorders are the most common forms of mental illness, only about 40 percent of sufferers receive treatment. Anxiety disorders often stem from abnormalities in the brain’s hippocampus and prefrontal cortex.
  • Attention-deficit/hyperactivity disorder, or ADHD, is a mental health condition that also affects adults but is far more often diagnosed in children.
  • ADHD is characterized by hyperactivity and an inability to stay focused.
  • Depression is another common mental health condition. It is the leading cause of disability worldwide and is often accompanied by anxiety. Depression can be marked by an array of symptoms, including persistent sadness, irritability, and changes in appetite.
  • The good news is that in general, anxiety and depression are highly treatable through various medications—which help the brain use certain chemicals more efficiently—and through forms of therapy

The Cleaner Wrasse: A Fish That Makes Other Fish Smarter - The Atlantic - 0 views

  • At particular sites, an itchy individual can attract the attention of the bluestreak cleaner wrasse—a slender fish, with blue and yellow markings and a prominent black stripe. On seeing these colors, the itchy “client” strikes a specific pose, allowing the wrasse to snake across its body, mouth, and gills, picking off parasites and dead skin along the way. The wrasse gets a meal. The client gets exfoliated. A single wrasse works for around four hours a day, and in that time, it can inspect more than 2,000 clients.
  • The wrasse are remarkably savvy about how they perform their services. Redouan Bshary, from the University of Neuchâtel, has shown that they sometimes cheat their clients by taking illicit bites of the protective mucus covering their skin. If the clients are watching, the wrasse restrain themselves from such shenanigans, in an effort to maintain their reputation. If disgruntled clients chase them, they try to make amends by offering a complementary fin massage. If high-status clients pop by—large, visiting predators like sharks or groupers—the cleaners prioritize them over smaller fish that live in the area. They’re surprisingly intelligent for fish.
  • And it seems that, by removing parasites, they also make other fish more intelligent.

  • she captured damselfish from various reefs and put them through a series of challenges. First, she put square plates on either side of their tank. One of these hid a chunk of food that the fish could smell but not reach, while the other hid a more accessible morsel. The damselfish had to learn which plate to swim up to—a simple spatial-memory test, and one that every individual passed. Next, Binning swapped the location of the correct plate; again, all the fish learned to change their behavior.
  • hings changed when she gave them a more difficult task. This time, they had to approach the correct plate based not on its location, but on its appearance. This skill—visual discrimination—is vitally important to a damselfish. “They have to learn very quickly, on the basis of color and pattern, which fish are safe to be around, and what competitors or friends look like,” says Binning. “They’re very good at that.”
  • Without the cleaners, the damselfish might also not have enough energy to fully fuel their demanding brains. They’re targeted by parasitic, bloodsucking crustaceans, which makes them “anemic, sluggish, and weak,” Binning says. When cleaners remove these parasites, the distressed damsels can divert their energies toward other matters—like thinking.

How does mother tongue affect second language acquisition? - Language Magazine - 0 views

  • Because cues that signal the beginning and ending of words can differ from language to language, a person’s native language can provide misleading information when learning to segment a second language into words.
  • “The moment we hear a new language, all of a sudden we hear a stream of sounds and don’t know where the words begin or end,” Tremblay said. “Even if we know words from the second language and can recognize them in isolation, we may not be able to locate these words in continuous speech, because a variety of processes affect how words are realized in context.”
  • Other cues, such as intonation, are harder to master and are more likely to be influenced by a speaker’s native language.
  • ...3 more annotations...
  • One of the more interesting findings is that when languages share more similarities but still have slight differences, it can be harder for second language learners to use the correct speech cues to identify words.
  • “For English speakers, the differences between English stress and French prominence are so salient that it ought to be obvious and they ought to readjust their system,”
  • Researchers also found that native French speakers who lived in France did better than native French speakers who lived in the U.S. at using French-like intonation cues to locate words in an artificial language.

Climate Change: The Technologies That Could Make All the Difference - WSJ - 0 views

  • The modularity of DAC systems implies that costs for CO2 removal might drop 90% to 95% over a couple of decades, just like the recent cost declines for other modular solutions such as wind turbines, solar panels and lithium-ion batteries.
  • Unlike other pollutants, what matters with carbon dioxide isn’t the location of its release but the total atmospheric accumulation. Releasing greenhouse gases in industrial corridors and then removing them from the atmosphere in remote locations has essentially the same net effect as if the carbon wasn’t emitted in the first place. That means we can deploy DAC systems wherever the energy for their operation is cheapest, ecosystem impacts are lowest, and the economic activity would be welcome.
  • A solar microgrid, which generates, stores and distributes clean energy to homes and facilities in a local network, provides a strong answer to these needs and wants. It can integrate with the main electric grid or disconnect and operate autonomously if the main grid is stressed or goes down. The physical pieces—solar panels, batteries and inverters—have been improving for a while. What’s new and coming, though, is the ability to orchestrate these different pieces into agile electric grids.
  • ...18 more annotations...
  • With digital tools and data science, demand for energy can now be sculpted locally to match available resources, reducing the number of power plants that utilities need to keep in reserve.
  • The key is giving consumers the ability to separate flexible energy uses—say, operating a Jacuzzi—from essential needs, which can now be done with phone apps for smart appliances and service panels.
  • Meanwhile, connections between groups of customers can be opened and closed as needed with modern, communicating circuit switchgear.
  • The good news is that record amounts of batteries are being installed in U.S. homes and on the electric grid, despite supply-chain bottlenecks.
  • The bad news is that current battery technology only offers a few hours of storage. What’s needed are more-powerful battery systems that can extend the length or scale of storing, which could be even more enabling to sun and wind power.
  • Two such solutions are on the horizon. Stationary metal-air batteries, such as iron-air batteries, don’t hold as much energy per kilogram as lithium-ion batteries so it takes a larger, heavier battery to do the job. But they are cheaper, iron is a plentiful metal, and the batteries, whose chemistry works via interaction of the metal with air, can be sized and installed to store and discharge a large level of electricity over days or weeks.
  • improved large iron-air batteries are poised to become a great new backup for renewable energy within the next couple of years to address those times of year when drops in renewable energy production can last for days and not hours.
  • For households, a battery configuration called a virtual power plant also holds huge potential to extend the use of renewables. These systems allow a local utility or electricity distributor to collect excess energy stored in multiple households’ battery systems and feed it back to the grid when there is a surge in demand or generation shortfall.
  • Electrification is a good choice for smaller vessels on short voyages, like the world’s largest all-electric ferry launched in Norway in 2021. It isn’t yet a viable option for ships on transoceanic voyages because batteries are still too large and heavy, though innovative approaches for battery swapping are being explored.
  • Greener Shipping
  • For longer voyages, e-ammonia, a hydrogen-derived fuel made with renewable energy, has been identified as a prime candidate, although work is needed to ensure safety. Ammonia has a higher energy density than some other options, making it a more economical option for powering large ships across oceans.
  • Among ammonia projects in the works, MAN Energy Solutions is developing engines that can run on conventional fossil fuel or ammonia, a coalition of Nordic partners is designing the world’s first ammonia-powered vessel, and Singapore is evaluating how to bunker the fuel.
  • Some EV makers such as Tesla are now embracing an older, less-expensive battery technology known as lithium-iron-phosphate, or LFP, used originally in scooters and small EVs in China
  • . It draws entirely on cheap and abundant minerals and is less flammable. The power density of LFP is less than NMC, but that disadvantage can be overcome by advances in vehicle design.
  • One approach being tested eliminates the outer packaging of the batteries altogether and directly installs cells, packed in layers, into a cavity in the EV’s body chassis.
  • Eventually, solid-state batteries—with a solid electrolyte made from common minerals like glass or ceramics—could become a key EV battery technology.
  • The solid electrolyte is more chemically stable, lighter, recharges faster and has many more lifetime recharging cycles than lithium-ion batteries, which depend on heavy liquid electrolytes.
  • these innovations are good news for those hoping to speed up EV adoption. They also suggest that batteries, far from becoming a standardized commodity, are going to be customized as auto makers create their own vehicle designs and battery makers develop proprietary platforms.

The Psychopath Makeover - The Chronicle Review - The Chronicle of Higher Education - 0 views

  • The eminent criminal psychologist and creator of the widely used Psychopathy Checklist paused before answering. "I think, in general, yes, society is becoming more psychopathic," he said. "I mean, there's stuff going on nowadays that we wouldn't have seen 20, even 10 years ago. Kids are becoming anesthetized to normal sexual behavior by early exposure to pornography on the Internet. Rent-a-friend sites are getting more popular on the Web, because folks are either too busy or too techy to make real ones. ... The recent hike in female criminality is particularly revealing. And don't even get me started on Wall Street."
  • in a survey that has so far tested 14,000 volunteers, Sara Konrath and her team at the University of Michigan's Institute for Social Research has found that college students' self-reported empathy levels (as measured by the Interpersonal Reactivity Index, a standardized questionnaire containing such items as "I often have tender, concerned feelings for people less fortunate than me" and "I try to look at everybody's side of a disagreement before I make a decision") have been in steady decline over the past three decades—since the inauguration of the scale, in fact, back in 1979. A particularly pronounced slump has been observed over the past 10 years. "College kids today are about 40 percent lower in empathy than their counterparts of 20 or 30 years ago," Konrath reports.
  • Imagining, it would seem, really does make it so. Whenever we read a story, our level of engagement is such that we "mentally simulate each new situation encountered in a narrative," according to one of the researchers, Nicole Speer. Our brains then interweave these newly encountered situations with knowledge and experience gleaned from our own lives to create an organic mosaic of dynamic mental syntheses.

"Many people see the current group of college students, sometimes called 'Generation Me,' " Konrath continues, "as one of the most self-centered, narcissistic, competitive, confident, and individualistic in recent history."
  • Reading a book carves brand-new neural pathways into the ancient cortical bedrock of our brains. It transforms the way we see the world—makes us, as Nicholas Carr puts it in his recent essay, "The Dreams of Readers," "more alert to the inner lives of others." We become vampires without being bitten—in other words, more empathic. Books make us see in a way that casual immersion in the Internet, and the quicksilver virtual world it offers, doesn't.
  • if society really is becoming more psychopathic, it's not all doom and gloom. In the right context, certain psychopathic characteristics can actually be very constructive. A neurosurgeon I spoke with (who rated high on the psychopathic spectrum) described the mind-set he enters before taking on a difficult operation as "an intoxication that sharpens rather than dulls the senses." In fact, in any kind of crisis, the most effective individuals are often those who stay calm—who are able to respond to the exigencies of the moment while at the same time maintaining the requisite degree of detachment.
  • mental toughness isn't the only characteristic that Special Forces soldiers have in common with psychopaths. There's also fearlessness.
  • I ask Andy whether he ever felt any regret over anything he'd done. Over the lives he'd taken on his numerous secret missions around the world. "No," he replies matter-of-factly, his arctic-blue eyes showing not the slightest trace of emotion. "You seriously don't think twice about it. When you're in a hostile situation, the primary objective is to pull the trigger before the other guy pulls the trigger. And when you pull it, you move on. Simple as that. Why stand there, dwelling on what you've done? Go down that route and chances are the last thing that goes through your head will be a bullet from an M16. "The regiment's motto is 'Who Dares Wins.' But sometimes it can be shortened to 'F--- It.' "
  • one of the things that we know about psychopaths is that the light switches of their brains aren't wired up in quite the same way as the rest of ours are—and that one area particularly affected is the amygdala, a peanut-size structure located right at the center of the circuit board. The amygdala is the brain's emotion-control tower. It polices our emotional airspace and is responsible for the way we feel about things. But in psychopaths, a section of this airspace, the part that corresponds to fear, is empty.
  • Turn down the signals to the amygdala, of course, and you're well on the way to giving someone a psychopath makeover. Indeed, Liane Young and her team in Boston have since kicked things up a notch and demonstrated that applying TMS to the right temporoparietal junction—a neural ZIP code within that neighborhood—has significant effects not just on lying ability but also on moral-reasoning ability: in particular, ascribing intentionality to others' actions.
  • at an undisclosed moment sometime within the next 60 seconds, the image you see at the present time will change, and images of a different nature will appear on the screen. These images will be violent. And nauseating. And of a graphic and disturbing nature. "As you view these images, changes in your heart rate, skin conductance, and EEG activity will be monitored and compared with the resting levels that are currently being recorded
  • "OK," says Nick. "Let's get the show on the road." He disappears behind us, leaving Andy and me merrily soaking up the incontinence ad. Results reveal later that, at this point, as we wait for something to happen, our physiological output readings are actually pretty similar. Our pulse rates are significantly higher than our normal resting levels, in anticipation of what's to come. But with the change of scene, an override switch flips somewhere in Andy's brain. And the ice-cold Special Forces soldier suddenly swings into action. As vivid, florid images of dismemberment, mutilation, torture, and execution flash up on the screen in front of us (so vivid, in fact, that Andy later confesses to actually being able to "smell" the blood: a "kind of sickly-sweet smell that you never, ever forget"), accompanied not by the ambient spa music of before but by blaring sirens and hissing white noise, his physiological readings start slipping into reverse. His pulse rate begins to slow. His GSR begins to drop, his EEG to quickly and dramatically attenuate. In fact, by the time the show is over, all three of Andy's physiological output measures are pooling below his baseline.
  • Nick has seen nothing like it. "It's almost as if he was gearing himself up for the challenge," he says. "And then, when the challenge eventually presented itself, his brain suddenly responded by injecting liquid nitrogen into his veins. Suddenly implemented a blanket neural cull of all surplus feral emotion. Suddenly locked down into a hypnotically deep code red of extreme and ruthless focus." He shakes his head, nonplused. "If I hadn't recorded those readings myself, I'm not sure I would have believed them," he continues. "OK, I've never tested Special Forces before. And maybe you'd expect a slight attenuation in response. But this guy was in total and utter control of the situation. So tuned in, it looked like he'd completely tuned out."
  • My physiological output readings, in contrast, went through the roof. Exactly like Andy's, they were well above baseline as I'd waited for the carnage to commence. But that's where the similarity ended. Rather than go down in the heat of battle, in the midst of the blood and guts, mine had appreciated exponentially. "At least it shows that the equipment is working properly," comments Nick. "And that you're a normal human being."
  • TMS can't penetrate far enough into the brain to reach the emotion and moral-reasoning precincts directly. But by damping down or turning up the regions of the cerebral cortex that have links with such areas, it can simulate the effects of deeper, more incursive influence.
  • Before the experiment, I'd been curious about the time scale: how long it would take me to begin to feel the rush. Now I had the answer: about 10 to 15 minutes. The same amount of time, I guess, that it would take most people to get a buzz out of a beer or a glass of wine.
  • The effects aren't entirely dissimilar. An easy, airy confidence. A transcendental loosening of inhibition. The inchoate stirrings of a subjective moral swagger: the encroaching, and somehow strangely spiritual, realization that hell, who gives a s---, anyway? There is, however, one notable exception. One glaring, unmistakable difference between this and the effects of alcohol. That's the lack of attendant sluggishness. The enhancement of attentional acuity and sharpness. An insuperable feeling of heightened, polished awareness. Sure, my conscience certainly feels like it's on ice, and my anxieties drowned with a half-dozen shots of transcranial magnetic Jack Daniel's. But, at the same time, my whole way of being feels as if it's been sumptuously spring-cleaned with light. My soul, or whatever you want to call it, immersed in a spiritual dishwasher.
  • So this, I think to myself, is how it feels to be a psychopath. To cruise through life knowing that no matter what you say or do, guilt, remorse, shame, pity, fear—all those familiar, everyday warning signals that might normally light up on your psychological dashboard—no longer trouble you.
  • I suddenly get a flash of insight. We talk about gender. We talk about class. We talk about color. And intelligence. And creed. But the most fundamental difference between one individual and another must surely be that of the presence, or absence, of conscience. Conscience is what hurts when everything else feels good. But what if it's as tough as old boots? What if one's conscience has an infinite, unlimited pain threshold and doesn't bat an eye when others are screaming in agony?

Holly the Cat's Incredible Journey - NYTimes.com - 0 views

  • “I really believe these stories, but they’re just hard to explain,” said Marc Bekoff, a behavioral ecologist at the University of Colorado. “Maybe being street-smart, maybe reading animal cues, maybe being able to read cars, maybe being a good hunter. I have no data for this.”There is, in fact, little scientific dogma on cat navigation. Migratory animals like birds, turtles and insects have been studied more closely, and use magnetic fields, olfactory cues, or orientation by the sun.
  • Strange, faraway locations would seem problematic, although he and Patrick Bateson, a behavioral biologist at Cambridge University, say that cats can sense smells across long distances. “Let’s say they associate the smell of pine with wind coming from the north, so they move in a southerly direction,”
  • Professor Tabor cited longer-distance reports he considered credible: Murka, a tortoiseshell in Russia, traveling about 325 miles home to Moscow from her owner’s mother’s house in Voronezh in 1989; Ninja, who returned to Farmington, Utah, in 1997, a year after her family moved from there to Mill Creek, Wash.; and Howie, an indoor Persian cat in Australia who in 1978 ran away from relatives his vacationing family left him with and eventually traveled 1,000 miles to his family’s home.

  • The closest, said Roger Tabor, a British cat biologist, may have been a 1954 study in Germany which cats placed in a covered circular maze with exits every 15 degrees most often exited in the direction of their homes, but more reliably if their homes were less than five kilometers away.
  • “We haven’t the slightest idea how they do this,” Mr. Galaxy said. “Anybody who says they do is lying, and, if you find it, please God, tell me what it is.”
  • Nobody knows how it happened: an indoor housecat who got lost on a family excursion managing, after two months and about 200 miles, to return to her hometown.

Taking back the economy: the market as a Res Publica | openDemocracy - 0 views

  • Freedom in the republican tradition requires enjoyment of the fundamental liberties with the security that only a rule of law can provide. You must be publicly protected and resourced in such a way that it is manifest to you and to all that under local (not unnecessarily restrictive) conventions: you can speak your mind, associate with your fellows, enjoy communal resources, locate where you will, move occupation and make use of what is yours, without reason for fearing anyone or deferring to anyone. You have the standing of a liber or free person; you enjoy equal status under the public order and you share equally in control over that order.
  • The rules of public order constitute the possibility of private life in the way in which the rules of a game like chess constitute the possibility of playing that game. They represent enabling (or enabling-cum-constraining) rules, not rules that merely regulate a pre-existing domain.
  • This republican image runs into sharp conflict with a more received picture, celebrated by right-wing libertarians, according to which the rules of public order regulate the private sphere rather than serving – now in the fashion of one culture, now in the fashion of another – to make it possible
  • ...6 more annotations...
  • On the republican picture, owning is a relationship that presupposes law, if only the inchoate law of informal custom.
  • The conflict between the images is important because it shows up in alternative visions of the economy and the relationship between the economy and the state.
  • You own something only insofar as it is a matter of accepted convention that given the way you came to hold it — given public recognition of the title you have to the property — you enjoy public protection against those who would take it from you
  • This view of property, prominent in Rousseau and presupposed in the broader republican tradition, is scarcely questionable in view of the salient diversity in systems of property
  • These observations, scarcely richer than platitudes, are important for giving us a perspective on the market and the economy, undermining the libertarian image. That picture represents the market as a res privata, a private thing, suggesting that the role of the state is merely to lay low the hills in the way of the market and smooth the paths for its operation. And so it depicts any other interventions of government in the market as dubious on philosophical, not just empirical, grounds.
  • this image accounts for the continuing attachment to austerity among those on the right. They are philosophically opposed to Keynesianism, not just opposed on empirical grounds, and their ideological stance makes empirically based arguments for Keynesianism invisible to them.

By boarding our self-driving boat you granted us the right to all feedback you provide during your journey. This includes the chemical composition of your sweat.
  • Unified logins let us get to know our audience in ways we never could before. They gave us their locations so that we might better tell them if it was raining outside. They told us where they lived and where they wanted to go so that we could deliver a more immersive map that better anticipated what they wanted to do–it let us very literally tell people what they should do today. As people began to see how very useful Google Now was, they began to give us even more information. They told us to dig through their e-mail for their boarding passes–Imagine if you had to find it on your own!–they finally gave us permission to track and store their search and web history so that we could give them better and better Cards. And then there is the imaging. They gave us tens of thousands of pictures of themselves so that we could pick the best ones–yes we appealed to their vanity to do this: We’ll make you look better and assure you present a smiling, wrinkle-free face to the world–but it allowed us to also stitch together three-dimensional representations. Hangout chats let us know who everybody’s friends were, and what they had to say to them. Verbal searches gave us our users’ voices. These were intermediary steps. But it let us know where people were at all times, what they thought, what they said, and of course how they looked. Sure, Google Now could tell you what to do.
  • “We learned so much about regulation with Google Health. It turns out, the government has rules about health records, and that people care about these rules for some reason. So we began looking around for ways to avoid regulation. For example, government regulation meant it was much easier to experiment with white space in Kenya than in the United States. So we started thinking: What if the entire world looked more like Kenya? Or, even better, Somalia? Places where there are no laws. We haven’t adapted mechanisms to deal with some of our old institutions like the law. We aren’t keeping up with the rate of change we caused through technology. If you look at the laws we have, they’re very old. A law can’t be right if it’s 50 years old. Like, it’s before the Internet

On Google Island, we’ve found those things to be distractions. If democracy worked so well, if a majority public opinion made something right, we would still have Jim Crow laws and Google Reader. We believe we can fix the world’s problems with better math. We can tear down the old and rebuild it with the new. Imagine Minecraft. Now imagine it photorealistic, and now imagine yourself living there, or at least, your Google Being living there. We already have the information. All we need is an invitation.

Skinner Marketing: We're the Rats, and Facebook Likes Are the Reward - Bill Davidow - T... - 0 views

  • the age of Skinnerian Marketing. Future applications making use of big data, location, maps, tracking of a browser's interests, and data streams coming from mobile and wearable devices, promise to usher in the era of unprecedented power in the hands of marketers, who are no longer merely appealing to our innate desires, but programming our behaviors.
  • In the 1930's, B. F. Skinner developed the concept of operant conditioning. He put pigeons and rats in Skinner boxes to study how he could modify their behavior using rewards and punishments.
  • Skinner's techniques of operant conditioning and his notorious theory of behavior modification were denounced by his critics 70 years ago as fascist, manipulative vehicles that could be used for government control.
  • ...6 more annotations...
  • They were right about control but wrong about the controllers. Our Internet handlers, not government, are using operant conditioning to modify our behavior today.
  • we now know how to design cue, activity, and reward systems to more effectively leverage our brain chemistry and program human behavior.
  • The beauty of the Internet is that by combining big data, behavioral targeting, wearable and mobile devices, and GPS, application developers can design more effective operant conditioning environments and keep us in virtual Skinner boxes as long as we have a smart phone in our pockets.
  • Operant conditioning techniques will and are currently being used to program the behavior of susceptible Internet users -- young men who play MMORPG (Massively Multiplayer Online Role-Playing Games) for forty hours a week, women who commit hours to social networks, shoppers seeking the thrill of a deal, and poker players.
  • As smart devices become integrated into our lives, retailers who will know where we are standing in stores and fast food restaurants and bars will find ways to provide us with cues to trigger behaviors.
  • The real question is how many hundreds of millions of us will become susceptible to what I believe will prove to be history's most potent marketing techniques.

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.
