They pay less attention to their surroundings. And neuroscientists can now see that brain behavior changes when people rely on turn-by-turn directions.
  • 2017, researchers asked subjects to navigate a virtual simulation of London’s Soho neighborhood and monitored their brain activity, specifically the hippocampus, which is integral to spatial navigation

  • The hippocampus is crucial to many aspects of daily life. It allows us to orient in space and know where we are by creating cognitive maps. It also allows us to recall events from the past, what is known as episodic memory. And, remarkably, it is the part of the brain that neuroscientists believe gives us the ability to imagine ourselves in the future.
  • “when people use tools such as GPS, they tend to engage less with navigation. Therefore, brain area responsible for navigation is less used, and consequently their brain areas involved in navigation tend to shrink.”
  • avigation aptitude appears to peak around age 19, and after that, most people slowly stop using spatial memory strategies to find their way, relying on habit instead.
  • “If we are paying attention to our environment, we are stimulating our hippocampus, and a bigger hippocampus seems to be protective against Alzheimer’s disease,” Bohbot told me in an email. “When we get lost, it activates the hippocampus, it gets us completely out of the habit mode. Getting lost is good!”

  • Faith is a concept that often enters the accounts of GPS-induced mishaps. “It kept saying it would navigate us a road,” said a Japanese tourist in Australia who, while attempting to reach North Stradbroke Island, drove into the Pacific Ocean. A man in West Yorkshire, England, who took his BMW off-road and nearly over a cliff, told authorities that his GPS “kept insisting the path was a road.” In perhaps the most infamous incident, a woman in Belgium asked GPS to take her to a destination less than two hours away. Two days later, she turned up in Croatia.
  • These episodes naturally inspire incredulity, if not outright mockery. After a couple of Swedes mistakenly followed their GPS to the city of Carpi (when they meant to visit Capri), an Italian tourism official dryly noted to the BBC that “Capri is an island. They did not even wonder why they didn’t cross any bridge or take any boat.” An Upper West Side blogger’s account of the man who interpreted “turn here” to mean onto a stairway in Riverside Park was headlined “GPS, Brain Fail Driver.”
  • several studies have demonstrated empirically what we already know instinctively. Cornell researchers who analyzed the behavior of drivers using GPS found drivers “detached” from the “environments that surround them.” Their conclusion: “GPS eliminated much of the need to pay attention.”

  • There is evidence that one’s cognitive map can deteriorate. A widely reported study published in 2006 demonstrated that the brains of London taxi drivers have larger than average amounts of gray matter in the area responsible for complex spatial relations. Brain scans of retired taxi drivers suggested that the volume of gray matter in those areas also decreases when that part of the brain is no longer being used as frequently. “I think it’s possible that if you went to someone doing a lot of active navigation, but just relying on GPS,” Hugo Spiers, one of the authors of the taxi study, hypothesized to me, “you’d actually get a reduction in that area.”
  • A consequence is a possible diminution of our “cognitive map,” a term introduced in 1948 by the psychologist Edward Tolman of the University of California, Berkeley. In a groundbreaking paper, Dr. Tolman analyzed several laboratory experiments involving rats and mazes. He argued that rats had the ability to develop not only cognitive “strip maps” — simple conceptions of the spatial relationship between two points — but also more comprehensive cognitive maps that encompassed the entire maze.
  • Could society’s embrace of GPS be eroding our cognitive maps? For Julia Frankenstein, a psychologist at the University of Freiburg’s Center for Cognitive Science, the danger of GPS is that “we are not forced to remember or process the information — as it is permanently ‘at hand,’ we need not think or decide for ourselves.” She has written that we “see the way from A to Z, but we don’t see the landmarks along the way.” In this sense, “developing a cognitive map from this reduced information is a bit like trying to get an entire musical piece from a few notes.” GPS abets a strip-map level of orientation with the world.
  • We seem driven (so to speak) to transform cars, conveyances that show us the world, into machines that also see the world for us.
  • For Dr. Tolman, the cognitive map was a fluid metaphor with myriad applications. He identified with his rats. Like them, a scientist runs the maze, turning strip maps into comprehensive maps — increasingly accurate models of the “great God-given maze which is our human world,” as he put it. The countless examples of “displaced aggression” he saw in that maze — “the poor Southern whites, who take it out on the Negros,” “we psychologists who criticize all other departments,” “Americans who criticize the Russians and the Russians who criticize us” — were all, to some degree, examples of strip-map comprehension, a blinkered view that failed to comprehend the big picture. “What in the name of Heaven and Psychology can we do about it?” he wrote. “My only answer is to preach again the virtues of reason — of, that is, broad cognitive maps.”

  • We rely on computers to fly our planes, find our cancers, design our buildings, audit our businesses. That's all well and good. But what happens when the computer fails?
  • On the evening of February 12, 2009, a Continental Connection commuter flight made its way through blustery weather between Newark, New Jersey, and Buffalo, New York.
  • The Q400 was well into its approach to the Buffalo airport, its landing gear down, its wing flaps out, when the pilot’s control yoke began to shudder noisily, a signal that the plane was losing lift and risked going into an aerodynamic stall. The autopilot disconnected, and the captain took over the controls. He reacted quickly, but he did precisely the wrong thing: he jerked back on the yoke, lifting the plane’s nose and reducing its airspeed, instead of pushing the yoke forward to gain velocity.
  • ...43 more annotations...
  • The crash, which killed all 49 people on board as well as one person on the ground, should never have happened.
  • aptain’s response to the stall warning, the investigators reported, “should have been automatic, but his improper flight control inputs were inconsistent with his training” and instead revealed “startle and confusion.
  • Automation has become so sophisticated that on a typical passenger flight, a human pilot holds the controls for a grand total of just three minutes.
  • We humans have been handing off chores, both physical and mental, to tools since the invention of the lever, the wheel, and the counting bead.
  • And that, many aviation and automation experts have concluded, is a problem. Overuse of automation erodes pilots’ expertise and dulls their reflexes,
  • No one doubts that autopilot has contributed to improvements in flight safety over the years. It reduces pilot fatigue and provides advance warnings of problems, and it can keep a plane airborne should the crew become disabled. But the steady overall decline in plane crashes masks the recent arrival of “a spectacularly new type of accident,”
  • “We’re forgetting how to fly.”
  • The experience of airlines should give us pause. It reveals that automation, for all its benefits, can take a toll on the performance and talents of those who rely on it. The implications go well beyond safety. Because automation alters how we act, how we learn, and what we know, it has an ethical dimension. The choices we make, or fail to make, about which tasks we hand off to machines shape our lives and the place we make for ourselves in the world.
  • What pilots spend a lot of time doing is monitoring screens and keying in data. They’ve become, it’s not much of an exaggeration to say, computer operators.
  • Examples of complacency and bias have been well documented in high-risk situations—on flight decks and battlefields, in factory control rooms—but recent studies suggest that the problems can bedevil anyone working with a computer
  • That may leave the person operating the computer to play the role of a high-tech clerk—entering data, monitoring outputs, and watching for failures. Rather than opening new frontiers of thought and action, software ends up narrowing our focus.
  • A labor-saving device doesn’t just provide a substitute for some isolated component of a job or other activity. It alters the character of the entire task, including the roles, attitudes, and skills of the people taking part.
  • when we work with computers, we often fall victim to two cognitive ailments—complacency and bias—that can undercut our performance and lead to mistakes. Automation complacency occurs when a computer lulls us into a false sense of security. Confident that the machine will work flawlessly and handle any problem that crops up, we allow our attention to drift.
  • Automation bias occurs when we place too much faith in the accuracy of the information coming through our monitors. Our trust in the software becomes so strong that we ignore or discount other information sources, including our own eyes and ears
  • Automation is different now. Computers can be programmed to perform complex activities in which a succession of tightly coordinated tasks is carried out through an evaluation of many variables. Many software programs take on intellectual work—observing and sensing, analyzing and judging, even making decisions—that until recently was considered the preserve of humans.
  • Automation turns us from actors into observers. Instead of manipulating the yoke, we watch the screen. That shift may make our lives easier, but it can also inhibit the development of expertise.
  • Since the late 1970s, psychologists have been documenting a phenomenon called the “generation effect.” It was first observed in studies of vocabulary, which revealed that people remember words much better when they actively call them to mind—when they generate them—than when they simply read them.
  • When you engage actively in a task, you set off intricate mental processes that allow you to retain more knowledge. You learn more and remember more. When you repeat the same task over a long period, your brain constructs specialized neural circuits dedicated to the activit
  • What looks like instinct is hard-won skill, skill that requires exactly the kind of struggle that modern software seeks to alleviate.
  • In many businesses, managers and other professionals have come to depend on decision-support systems to analyze information and suggest courses of action. Accountants, for example, use the systems in corporate audits. The applications speed the work, but some signs suggest that as the software becomes more capable, the accountants become less so.
  • You can put limits on the scope of automation, making sure that people working with computers perform challenging tasks rather than merely observing.
  • Experts used to assume that there were limits to the ability of programmers to automate complicated tasks, particularly those involving sensory perception, pattern recognition, and conceptual knowledge
  • Who needs humans, anyway? That question, in one rhetorical form or another, comes up frequently in discussions of automation. If computers’ abilities are expanding so quickly and if people, by comparison, seem slow, clumsy, and error-prone, why not build immaculately self-contained systems that perform flawlessly without any human oversight or intervention? Why not take the human factor out of the equation?
  • The cure for imperfect automation is total automation.
  • That idea is seductive, but no machine is infallible. Sooner or later, even the most advanced technology will break down, misfire, or, in the case of a computerized system, encounter circumstances that its designers never anticipated. As automation technologies become more complex, relying on interdependencies among algorithms, databases, sensors, and mechanical parts, the potential sources of failure multiply. They also become harder to detect.
  • conundrum of computer automation.
  • Because many system designers assume that human operators are “unreliable and inefficient,” at least when compared with a computer, they strive to give the operators as small a role as possible.
  • People end up functioning as mere monitors, passive watchers of screens. That’s a job that humans, with our notoriously wandering minds, are especially bad at
  • people have trouble maintaining their attention on a stable display of information for more than half an hour. “This means,” Bainbridge observed, “that it is humanly impossible to carry out the basic function of monitoring for unlikely abnormalities.”
  • a person’s skills “deteriorate when they are not used,” even an experienced operator will eventually begin to act like an inexperienced one if restricted to just watching.
  • You can program software to shift control back to human operators at frequent but irregular intervals; knowing that they may need to take command at any moment keeps people engaged, promoting situational awareness and learning.
  • What’s most astonishing, and unsettling, about computer automation is that it’s still in its early stages.
  • most software applications don’t foster learning and engagement. In fact, they have the opposite effect. That’s because taking the steps necessary to promote the development and maintenance of expertise almost always entails a sacrifice of speed and productivity.
  • Learning requires inefficiency. Businesses, which seek to maximize productivity and profit, would rarely accept such a trade-off. Individuals, too, almost always seek efficiency and convenience.
  • Abstract concerns about the fate of human talent can’t compete with the allure of saving time and money.
  • The small island of Igloolik, off the coast of the Melville Peninsula in the Nunavut territory of northern Canada, is a bewildering place in the winter.
  • , Inuit hunters have for some 4,000 years ventured out from their homes on the island and traveled across miles of ice and tundra to search for game. The hunters’ ability to navigate vast stretches of the barren Arctic terrain, where landmarks are few, snow formations are in constant flux, and trails disappear overnight, has amazed explorers and scientists for centuries. The Inuit’s extraordinary way-finding skills are born not of technological prowess—they long eschewed maps and compasses—but of a profound understanding of winds, snowdrift patterns, animal behavior, stars, and tides.
  • The Igloolik hunters have begun to rely on computer-generated maps to get around. Adoption of GPS technology has been particularly strong among younger Inuit, and it’s not hard to understand why.
  • But as GPS devices have proliferated on Igloolik, reports of serious accidents during hunts have spread. A hunter who hasn’t developed way-finding skills can easily become lost, particularly if his GPS receiver fails.
  • The routes so meticulously plotted on satellite maps can also give hunters tunnel vision, leading them onto thin ice or into other hazards a skilled navigator would avoid.
  • An Inuit on a GPS-equipped snowmobile is not so different from a suburban commuter in a GPS-equipped SUV: as he devotes his attention to the instructions coming from the computer, he loses sight of his surroundings. He travels “blindfolded,” as Aporta puts it
  • A unique talent that has distinguished a people for centuries may evaporate in a generation.
  • Computer automation severs the ends from the means. It makes getting what we want easier, but it distances us from the work of knowing. As we transform ourselves into creatures of the screen, we face an existential question: Does our essence still lie in what we know, or are we now content to be defined by what we want?

    Automation increases efficiency and speed of tasks, but decreases the individual's knowledge of a task and decrease's a human's ability to learn.

  • Before Kahneman and Tversky, people who thought about social problems and human behavior tended to assume that we are mostly rational agents. They assumed that people have control over the most important parts of their own thinking. They assumed that people are basically sensible utility-maximizers and that when they depart from reason it’s because some passion like fear or love has distorted their judgment.
  • Kahneman and Tversky conducted experiments. They proved that actual human behavior often deviates from the old models and that the flaws are not just in the passions but in the machinery of cognition. They demonstrated that people rely on unconscious biases and rules of thumb to navigate the world, for good and ill. Many of these biases have become famous: priming, framing, loss-aversion.
  • We are dual process thinkers. We have two interrelated systems running in our heads. One is slow, deliberate and arduous (our conscious reasoning). The other is fast, associative, automatic and supple (our unconscious pattern recognition). There is now a complex debate over the relative strengths and weaknesses of these two systems. In popular terms, think of it as the debate between “Moneyball” (look at the data) and “Blink” (go with your intuition).
  • ...3 more annotations...
  • We are not blank slates. All humans seem to share similar sets of biases. There is such a thing as universal human nature. The trick is to understand the universals and how tightly or loosely they tie us down.
  • We are players in a game we don’t understand. Most of our own thinking is below awareness. Fifty years ago, people may have assumed we are captains of our own ships, but, in fact, our behavior is often aroused by context in ways we can’t see. Our biases frequently cause us to want the wrong things. Our perceptions and memories are slippery, especially about our own mental states. Our free will is bounded. We have much less control over ourselves than we thought.
  • They also figured out ways to navigate around our shortcomings. Kahneman champions the idea of “adversarial collaboration” — when studying something, work with people you disagree with. Tversky had a wise maxim: “Let us take what the terrain gives.” Don’t overreach. Understand what your circumstances are offer

  • We’ve all done it. Run upstairs to get your keys, but forget that it is them you’re looking for once you get to the bedroom. Open the fridge door and reach for the middle shelf only to realise that we can't remember why we opened the fridge in the first place. Or wait for a moment to interrupt a friend to find that the burning issue that made us want to interrupt has now vanished from our minds
  • It’s known as the “Doorway Effect”, and it reveals some important features of how our minds are organised. Understanding this might help us appreciate those temporary moments of forgetfulness as more than just an annoyance
  • “What are you doing today?” she asks the first. “I’m putting brick after sodding brick on top of another,” sighs the first. “What are you doing today?” she asks the second. “I’m building a wall,” is the simple reply. But the third builder swells with pride when asked, and replies: “I’m building a cathedral!”
  • ...7 more annotations...
  • Maybe you heard that story as encouragement to think of the big picture, but to the psychologist in you the important moral is that any action has to be thought of at multiple levels if you are going to carry it out successfully. The third builder might have the most inspiring view of their day-job, but nobody can build a cathedral without figuring out how to successfully put one brick on top of another like the first builder.
  • As we move through our days our attention shifts between these levels – from our goals and ambitions, to plans and strategies, and to the lowest levels, our concrete actions. When things are going well, often in familiar situations, we keep our attention on what we want and how we do it seems to take care of itself. If you’re a skilled driver then you manage the gears, indicators and wheel automatically, and your attention is probably caught up in the less routine business of navigating the traffic or talking to your passengers. When things are less routine we have to shift our attention to the details of what we’re doing, taking our minds off the bigger picture for a moment.
  • The way our attention moves up and down the hierarchy of action is what allows us to carry out complex behaviours, stitching together a coherent plan over multiple moments, in multiple places or requiring multiple actions.
  • The Doorway Effect occurs when our attention moves between levels, and it reflects the reliance of our memories – even memories for what we were about to do – on the environment we’re in.
  • Imagine that we’re going upstairs to get our keys and forget that it is the keys we came for as soon as we enter the bedroom. Psychologically, what has happened is that the plan (“Keys!”) has been forgotten even in the middle of implementing a necessary part of the strategy (“Go to bedroom!”). Probably the plan itself is part of a larger plan (“Get ready to leave the house!”), which is part of plans on a wider and wider scale (“Go to work!”, “Keep my job!”, “Be a productive and responsible citizen”, or whatever). Each scale requires attention at some point. Somewhere in navigating this complex hierarchy the need for keys popped into mind, and like a circus performer setting plates spinning on poles, your attention focussed on it long enough to construct a plan, but then moved on to the next plate
  • And sometimes spinning plates fall. Our memories, even for our goals, are embedded in webs of associations. That can be the physical environment in which we form them, which is why revisiting our childhood home can bring back a flood of previously forgotten memories, or it can be the mental environment – the set of things we were just thinking about when that thing popped into mind.
  • The Doorway Effect occurs because we change both the physical and mental environments, moving to a different room and thinking about different things. That hastily thought up goal, which was probably only one plate among the many we’re trying to spin, gets forgotten when the context changes.

self-driving car automation ethics

shared by Javier E on 20 Mar 18 - No Cached
  • it’s a good time for a critical review of the technical literature of self-driving cars. This literature reveals that autonomous vehicles don’t work as well as their creators might like the public to believe.
  • The world is a 3-D grid with x, y, and z coordinates. The car moves through the grid from point A to point B, using highly precise GPS measurements gathered from nearby satellites. Several other systems operate at the same time. The car’s sensors bounce out laser radar waves and measure the response time to build a “picture” of what is outside.
  • It is a masterfully designed, intricate computational system. However, there are dangers.
  • ...11 more annotations...
  • Self-driving cars navigate by GPS. What happens if a self-driving school bus is speeding down the highway and loses its navigation system at 75 mph because of a jammer in the next lane?
  • Because they are not calculating the trajectory for the stationary fire truck, only for objects in motion (like pedestrians or bicyclists), they can’t react quickly to register a previously stationary object as an object in motion.
  • If the car was programmed to save the car’s occupants at the expense of pedestrians, the autonomous-car industry is facing its first public moment of moral reckoning.
  • This kind of blind optimism about technology, the assumption that tech is always the right answer, is a kind of bias that I call technochauvinism.
  • an overwhelming number of tech people (and investors) seem to want self-driving cars so badly that they are willing to ignore evidence suggesting that self-driving cars could cause as much harm as good
  • By this point, many people know about the trolley problem as an example of an ethical decision that has to be programmed into a self-driving car.
  • With driving, the stakes are much higher. In a self-driving car, death is an unavoidable feature, not a bug.
  • t imagine the opposite scenario: The car is programmed to sacrifice the driver and the occupants to preserve the lives of bystanders. Would you get into that car with your child? Would you let anyone in your family ride in it? Do you want to be on the road, or on the sidewalk, or on a bicycle, next to cars that have no drivers and have unreliable software that is designed to kill you or the driver?
  • Plenty of people want self-driving cars to make their lives easier, but self-driving cars aren’t the only way to fix America’s traffic problems. One straightforward solution would be to invest more in public transportation.
  • Public-transportation funding is a complex issue that requires massive, collaborative effort over a period of years. It involves government bureaucracy. This is exactly the kind of project that tech people often avoid attacking, because it takes a really long time and the fixes are complicated.
  • Plenty of people, including technologists, are sounding warnings about self-driving cars and how they attempt to tackle very hard problems that haven’t yet been solved. People are warning of a likely future for self-driving cars that is neither safe nor ethical nor toward the greater good. Still, &nbsp;the idea that self-driving cars are nifty and coming soon is often the accepted wisdom, and there’s a tendency to forget that technologists have been saying “coming soon” for decades now.

What Is Synesthesia? Definition and Types - 0 views

shared by runlai_jiang on 15 Jan 18 - No Cached
  • The term "synesthesia" comes from the Greek words&nbsp;syn, which means "together", and&nbsp;aisthesis, which means "sensation." Synesthesia is a perception in which stimulating one sensory or cognitive pathway&nbsp; causes experiences in another sense or cognitive pathway. In other words, a sense or concept is connected to a different sense or concept, such as hearing a color or tasting a word. The connection between pathways is involuntary and consistent over time, rather than conscious or arbitrary.
  • Types of SynesthesiaThere are many different types of synesthesia, but they may be categorized as falling into one of two groups: associative&nbsp;synesthesia and projective synesthesia. An associate feels a connection between a stimulus and a sense, w
  • There are at least 80 known types of synesthesia, but some are more common than others: Chromesthesia:&nbsp;In this common form of synesthesia, sounds and colors are associated with each other. For example, the musical note "D" may correspond to seeing the color green.Grapheme-color synesthesia: This is a common form of synesthesia characterized by seeing graphemes (letter or numerals) shaded with a color. Synesthetes don't associate the same colors for a grapheme as each other, although the letter "A" does appear to be red to many individuals. Persons who experience grapheme-color synesthesia sometimes report seeing impossible colors when red and green or blue and yellow graphemes appear next to each other in a word or number. Number form: A number form is a mental shape or map of numbers resulting from seeing or thinking about numbers.Lexical-gustatory synesthesia: This a rare type of synesthesia in which hearing a word results in tasting a flavor. For example, a person's name might taste like chocolate.Mirror-touch synesthesia: While rare, mirror-touch synesthesia is noteworthy because it can be disruptive to a synesthete's life. In this form of synesthesia, an individual feels the same sensation in response to a stimulus as another person. For example, seeing a person being tapped on the shoulder would cause the synesthete to feel a tap on

  • How Synesthesia WorksScientists have yet to make a definitive determination of the mechanism of synesthesia. It may be due to increased cross-talk between specialized regions of the brain. Another possible mechanism is that inhibition in a neural pathway is reduced in synesthetes, allowing multi-sensory processing of stimuli. Some researchers believe synesthesia is based on the way the brain extracts and assigns the meaning of a stimulus (ideasthesia).
  • Who Has Synesthesia?Julia Simner, a psychologist studying synesthesia at&nbsp;of the University of Edinburgh, estimates at least 4% of the population has synesthesia and that over 1% of people have grapheme-color synesthesia (colored numbers and letters). More women have synesthesia than men. Some research suggests the incidenc
  • Can You Develop Synesthesia?There are documented cases of non-synesthetes developing synesthesia. Specifically, head trauma, stroke, brain tumors, and temporal lobe epilepsy may produce synesthesia. Temporary synesthesia may result from exposure to the psychedelic drugs mescaline or LSD, from sensory deprivation, or from meditation.

  • It turns out engines aren’t the major culprit anymore. New airplanes are much quieter. It’s the “whoosh” that big airplanes make racing through the air.
  • Computer models suggest slowing departures by 30 knots—about 35 miles an hour—would reduce noise on the ground significantly.

  • The FAA says it’s impressed and is moving forward with recommendations Boston has made.
  • . A working group is forming to evaluate the main recommendation to slow departing jets to a speed limit of 220 knots during the climb to 10,000 feet, down from 250 knots.
  • New routes put planes over quiet communities. Complaints soared. Phoenix neighborhoods sued the FAA; Chicago neighborhoods are pushing for rotating runway use. Neighborhoods from California to Washington, D.C., are fighting the new procedures that airlines and the FAA insist are vital to future travel.
  • “It’s a concentration problem. It’s a frequency problem. It’s not really a noise problem.”
  • “The flights wake you up. We get a lot of complaints from young families with children,” says Mr. Wright, a data analyst who works from home for a major health-care company.
  • In Boston, an analysis suggested only 54% of the complaints Massport received resulted from noise louder than 45 decibels—about the level of background noise. When it’s relentless, you notice it more.
  • With a 30-knot reduction, noise directly under the flight track would decrease by between 1.5 and 5 decibels and the footprint on the ground would get a lot skinnier, sharply reducing the number of people affected, Mr. Hansman says.
  • The industry trade association Airlines for America has offered cautious support of the Boston recommendations. In a statement, the group said the changes must be safe, work with a variety of aircraft and not reduce the airport’s capacity for takeoffs and landings.
  • Air-traffic controllers will need to delay a departure a bit to put more room between a slower plane and a faster one, or modify its course slightly.

Memory

  • Technology isn't always good for your memory. Overusing map apps can alter our navigational skills. Information overload can make us forgetful. Most of us treat Google like an external hard drive for information we might have once committed to memory. And all those selfies and picturesque vistas we photograph on vacation might be affecting how we remember the trip, according to a new study in the Journal of Experimental Social Psychology spotted by Vox.
  • The researchers conclude that recording an experience "may prevent people from remembering the very events they are attempting to preserve." Their study ends on a dark note: "Ironically, our results suggest that using media to preserve these moments may prevent people from fully experiencing them in the first place.

smartphone weaponisation tech psychology manipulation internet social media education

  • the brief return of one of my favorite discursive topics—are the kids all right?—in one of my least-favorite variations: why shouldn’t each of them have a smartphone and tablet?
  • One camp says yes, the kids are fine
  • complaints about screen time merely conceal a desire to punish hard-working parents for marginally benefiting from climbing luxury standards, provide examples of the moral panic occasioned by all new technologies, or mistakenly blame screens for ill effects caused by the general political situation.
  • ...38 more annotations...
  • No, says the other camp, led by Jonathan Haidt; the kids are not all right, their devices are partly to blame, and here are the studies showing why.
  • we should not wait for the replication crisis in the social sciences to resolve itself before we consider the question of whether the naysayers are on to something. And normal powers of observation and imagination should be sufficient to make us at least wary of smartphones.
  • These powerful instruments represent a technological advance on par with that of the power loom or the automobile
  • The achievement can be difficult to properly appreciate because instead of exerting power over physical processes and raw materials, they operate on social processes and the human psyche: They are designed to maximize attention, to make it as difficult as possible to look away.
  • they have transformed the qualitative experience of existing in the world. They give a person’s sociality the appearance and feeling of a theoretically endless open network, while in reality, algorithms quietly sort users into ideological, aesthetic, memetic cattle chutes of content.
  • Importantly, the process by which smartphones change us requires no agency or judgment on the part of a teen user, and yet that process is designed to provide what feels like a perfectly natural, inevitable, and complete experience of the world.
  • Smartphones offer a tactile portal to a novel digital environment, and this environment is not the kind of space you enter and leave
  • One reason commonly offered for maintaining our socio-technological status quo is that nothing really has changed with the advent of the internet, of Instagram, of Tiktok and Youtube and 4Chan
  • It is instead a complete shadow world of endless images; disembodied, manipulable personas; and the ever-present gaze of others. It lives in your pocket and in your mind.
  • The price you pay for its availability—and the engine of its functioning—is that you are always available to it, as well. Unless you have a strength of will that eludes most adults, its emissaries can find you at any hour and in any place to issue your summons to the grim pleasure palace.
  • the self-restraint and self-discipline required to use a smartphone well—that is, to treat it purely as an occasional tool rather than as a totalizing way of life—are unreasonable things to demand of teenagers
  • these are unreasonable things to demand of me, a fully adult woman
  • To enjoy the conveniences that a smartphone offers, I must struggle against the lure of the permanent scroll, the notification, the urge to fix my eyes on the circle of light and keep them fixed. I must resist the default pseudo-activity the smartphone always calls its user back to, if I want to have any hope of filling the moments of my day with the real activity I believe is actually valuable.
  • for a child or teen still learning the rudiments of self-control, still learning what is valuable and fulfilling, still learning how to prioritize what is good over the impulse of the moment, it is an absurd bar to be asked to clear
  • The expectation that children and adolescents will navigate new technologies with fully formed and muscular capacities for reason and responsibility often seems to go along with a larger abdication of responsibility on the part of the adults involved.
  • adults have frequently given in to a Faustian temptation: offering up their children’s generation to be used as guinea pigs in a mass longitudinal study in exchange for a bit more room to breathe in their own undeniably difficult roles as educators, caretakers, and parents.
  • It is not a particular activity that you start and stop and resume, and it is not a social scene that you might abandon when it suits you.
  • And this we must do without waiting for social science to hand us a comprehensive mandate it is fundamentally unable to provide; without cowering in panic over moral panics
  • The pre-internet advertising world was vicious, to be sure, but when the “pre-” came off, its vices were moved into a compound interest account. In the world of online advertising, at any moment, in any place, a user engaged in an infinite scroll might be presented with native content about how one Instagram model learned to accept her chunky (size 4) thighs, while in the next clip, another model relates how a local dermatologist saved her from becoming an unlovable crone at the age of 25
  • developing pathological interests and capacities used to take a lot more work than it does now
  • You had to seek it out, as you once had to seek out pornography and look someone in the eye while paying for it. You were not funneled into it by an omnipresent stream of algorithmically curated content—the ambience of digital life, so easily mistaken by the person experiencing it as fundamentally similar to the non-purposive ambience of the natural world.
  • And when interpersonal relations between teens become sour, nasty, or abusive, as they often do and always have, the unbalancing effects of transposing social life to the internet become quite clear
  • For both young men and young women, the pornographic scenario—dominance and degradation, exposure and monetization—creates an experiential framework for desires that they are barely experienced enough to understand.
  • This is not a world I want to live in. I think it hurts everyone; but I especially think it hurts those young enough to receive it as a natural state of affairs rather than as a profound innovation.
  • so I am baffled by the most routine objection to any blaming of smartphones for our society-wide implosion of teenagers’ mental health,
  • In short, and inevitably, today’s teenagers are suffering from capitalism—specifically “late capitalism,
  • what shocks me about this rhetorical approach is the rush to play defense for Apple and its peers, the impulse to wield the abstract concept of capitalism as a shield for actually existing, extremely powerful, demonstrably ruthless capitalist actors.
  • This motley alliance of left-coded theory about the evils of business and right-coded praxis in defense of a particular evil business can be explained, I think, by a deeper desire than overthrowing capitalism. It is the desire not to be a prude or hysteric of bumpkin
  • No one wants to come down on the side of tamping off pleasures and suppressing teen activity.
  • No one wants to be the shrill or leaden antagonist of a thousand beloved movies, inciting moral panics, scheming about how to stop the youths from dancing on Sunday.
  • But commercial pioneers are only just beginning to explore new frontiers in the profit-driven, smartphone-enabled weaponization of our own pleasures against us
  • To limit your moral imagination to the archetypes of the fun-loving rebel versus the stodgy enforcers in response to this emerging reality is to choose to navigate it with blinders on, to be a useful idiot for the robber barons of online life rather than a challenger to the corrupt order they maintain.
  • The very basic question that needs to be asked with every product rollout and implementation is what technologies enable a good human life?
  • this question is not, ultimately, the province of social scientists, notwithstanding how useful their work may be on the narrower questions involved. It is the free privilege, it is the heavy burden, for all of us, to think—to deliberate and make judgments about human good, about what kind of world we want to live in, and to take action according to that thought.
  • I am not sure how to build a world in which childrens and adolescents, at least, do not feel they need to live their whole lives online.
  • whatever particular solutions emerge from our negotiations with each other and our reckonings with the force of cultural momentum, they will remain unavailable until we give ourselves permission to set the terms of our common life.
  • But the environments in which humans find themselves vary significantly, and in ways that have equally significant downstream effects on the particular expression of human nature in that context.
  • most of all, without affording Apple, Facebook, Google, and their ilk the defensive allegiance we should reserve for each other.

How to Navigate a 'Quarterlife' Crisis - The New York Times - 0 views

  • Satya Doyle Byock, a 39-year-old therapist, noticed a shift in tone over the past few years in the young people who streamed into her office: frenetic, frazzled clients in their late teens, 20s and 30s. They were unnerved and unmoored, constantly feeling like something was wrong with them.
  • “Crippling anxiety, depression, anguish, and disorientation are effectively the norm,”
  • her new book, “Quarterlife: The Search for Self in Early Adulthood.” The book uses anecdotes from Ms. Byock’s practice to outline obstacles faced by today’s young adults — roughly between the ages of 16 and 36 — and how to deal with them.
  • ...40 more annotations...
  • Just like midlife, quarterlife can bring its own crisis — trying to separate from your parents or caregivers and forge a sense of self is a struggle. But the generation entering adulthood now faces novel, sometimes debilitating, challenges.
  • Many find themselves so mired in day-to-day monetary concerns, from the relentless crush of student debt to the swelling costs of everything, that they feel unable to consider what they want for themselves long term
  • “We’ve been constrained by this myth that you graduate from college and you start your life,” she said. Without the social script previous generations followed — graduate college, marry, raise a family — Ms. Byock said her young clients often flailed around in a state of extended adolescence.
  • nearly one-third of Gen Z adults are living with their parents or other relatives and plan to stay there.
  • Many young people today struggle to afford college or decide not to attend, and the “existential crisis” that used to hit after graduation descends earlier and earlier
  • Ms. Byock said to pay attention to what you’re naturally curious about, and not to dismiss your interests as stupid or futile.
  • Experts said those entering adulthood need clear guidance for how to make it out of the muddle. Here are their top pieces of advice on how to navigate a quarterlife crisis today.
  • She recommends scheduling reminders to check in with yourself, roughly every three months, to examine where you are in your life and whether you feel stuck or dissatisfied
  • From there, she said, you can start to identify aspects of your life that you want to change.
  • “Start to give your own inner life the respect that it’s due,”
  • But quarterlife is about becoming a whole person, Ms. Byock said, and both groups need to absorb each other’s characteristics to balance themselves out
  • However, there is a difference between self-interest and self-indulgence, Ms. Byock said. Investigating and interrogating who you are takes work. “It’s not just about choosing your labels and being done,” she said.
  • Be patient.
  • Quarterlifers may feel pressure to race through each step of their lives, Ms. Byock said, craving the sense of achievement that comes with completing a task.
  • But learning to listen to oneself is a lifelong process.
  • Instead of searching for quick fixes, she said, young adults should think about longer-term goals: starting therapy that stretches beyond a handful of sessions, building healthy nutrition and exercise habits, working toward self-reliance.
  • “I know that seems sort of absurdly large and huge in scope,” she said. “But it’s allowing ourselves to meander and move through life, versus just ‘Check the boxes and get it right.’”
  • take stock of your day-to-day life and notice where things are missing. She groups quarterlifers into two categories: “stability types” and “meaning types.”
  • “Stability types” are seen by others as solid and stable. They prioritize a sense of security, succeed in their careers and may pursue building a family.
  • “But there’s a sense of emptiness and a sense of faking it,” she said. “They think this couldn’t possibly be all that life is about.”
  • On the other end of the spectrum, there are “meaning types” who are typically artists; they have intense creative passions but have a hard time dealing with day-to-day tasks
  • “These are folks for whom doing what society expects of you is so overwhelming and so discordant with their own sense of self that they seem to constantly be floundering,” she said. “They can’t quite figure it out.”
  • That paralysis is often exacerbated by mounting climate anxiety and the slog of a multiyear pandemic that has left many young people mourning family and friends, or smaller losses like a conventional college experience or the traditions of starting a first job.
  • Stability types need to think about how to give their lives a sense of passion and purpose. And meaning types need to find security, perhaps by starting with a consistent routine that can both anchor and unlock creativity.
  • perhaps the prototypical inspiration for staying calm in chaos: Yoda. The Jedi master is “one of the few images we have of what feeling quiet amid extreme pain and apocalypse can look like,
  • Even when there seems to be little stability externally, she said, quarterlifers can try to create their own steadiness.
  • establishing habits that help you ground yourself as a young adult is critical because transitional periods make us more susceptible to burnout
  • He suggests building a practical tool kit of self-care practices, like regularly taking stock of what you’re grateful for, taking controlled breaths and maintaining healthy nutrition and exercise routines. “These are techniques that can help you find clarity,”
  • Don’t be afraid to make a big change.
  • It’s important to identify what aspects of your life you have the power to alter, Dr. Brown said. “You can’t change an annoying boss,” he said, “but you might be able to plan a career change.”
  • That’s easier said than done, he acknowledged, and young adults should weigh the risks of continuing to live in their status quo — staying in their hometown, or lingering in a career that doesn’t excite them — with the potential benefits of trying something new.
  • quarterlife is typically “the freest stage of the whole life span,
  • Young adults may have an easier time moving to a new city or starting a new job than their older counterparts would.
  • Know when to call your parents — and when to call on yourself.
  • Quarterlife is about the journey from dependence to independence, Ms. Byock said — learning to rely on ourselves, after, for some, growing up in a culture of helicopter parenting and hands-on family dynamics.
  • there are ways your relationship with your parents can evolve, helping you carve out more independence
  • That can involve talking about family history and past memories or asking questions about your parents’ upbringing
  • “You’re transitioning the relationship from one of hierarchy to one of friendship,” she said. “It isn’t just about moving away or getting physical distance.”
  • Every quarterlifer typically has a moment when they know they need to step away from their parents and to face obstacles on their own
  • That doesn’t mean you can’t, or shouldn’t, still depend on your parents in moments of crisis, she said. “I don’t think it’s just about never needing one’s parents again,” she said. “But it’s about doing the subtle work within oneself to know: This is a time I need to stand on my own.”
