BBC - Future - Why your body jerks before you fall asleep - 0 views

  • f you have ever wondered why people’s arms and legs twitch suddenly as they are drifting off to sleep, our resident psychologist Tom Stafford has the answer.
  • we give up our bodies to sleep, sudden twitches escape our brains, causing our arms and legs to jerk. Some people are startled by them, others are embarrassed. Me, I am fascinated by these twitches, known as hypnic jerks.
  • ormally we are paralysed while we sleep. Even during the most vivid dreams our muscles stay relaxed and still, showing little sign of our internal excitement. Events in the outside world usually get ignored

  • The most common movements we make while asleep are rapid eye-movements. When we dream, our eyes move according to what we are dreaming about.

Is Most of Our DNA Garbage? - NYTimes.com - 0 views

  • Is Most of Our DNA Garbage?
  • Gregory believes that while some noncoding DNA is essential, most probably does nothing for us at all, and until recently, most biologists agreed with him.
  • Recent studies have revealed a wealth of new pieces of noncoding DNA that do seem to be as important to our survival as our more familiar genes.
  • ...6 more annotations...
  • Large-scale surveys of the genome have led a number of researchers to expect that the human genome will turn out to be even more full of activity than previously thought.
  • “It was pretty much a case of hubris to imagine that we could dispense with any part of the genome — as if we knew enough to say it wasn’t functional.”
  • If every piece of the genome were essential, then many of those mutations would lead to significant birth defects, with the defects only multiplying over the course of generations; in less than a century, the species would become extinct.
  • “Much of what has been called ‘junk DNA’ in the human genome is actually a massive control panel with millions of switches regulating the activity of our genes.”
  • It’s no coincidence, researchers like Gregory argue, that bona fide creationists have used recent changes in the thinking about junk DNA to try to turn back the clock to the days before Darwin. (The recent studies on noncoding DNA “clearly demonstrate we are ‘fearfully and wonderfully made’ by our Creator God,” declared the Institute for Creation Research.)
  • Over millions of years, the human genome has spontaneously gotten bigger, swelling with useless copies of genes and new transposable elements.

Evolution and the American Myth of the Individual - NYTimes.com - 0 views

  • the country’s two main political parties have “fundamental philosophical differences.” But what exactly does that mean?
  • In a broad sense, Democrats, particularly the more liberal among them, are more likely to embrace the communal nature of individual lives and to strive for policies that emphasize that understanding.
  • Republicans, especially libertarians and Tea Party members on the ideological fringe, however, often trace their ideas about freedom and liberty back to Enlightenment thinkers of the 17th and 18th centuries, who argued that the individual is the true measure of human value, and each of us is naturally entitled to act in our own best interests free of interference by others. Self-described libertarians generally also pride themselves on their high valuation of logic and reasoning over emotion.

  • Philosophers from Aristotle to Hegel have emphasized that human beings are essentially social creatures, that the idea of an isolated individual is a misleading abstraction. So it is not just ironic but instructive that modern evolutionary research, anthropology, cognitive psychology and neuroscience have come down on the side of the philosophers who have argued that the basic unit of human social life is not and never has been the selfish, self-serving individual.
  • The irony here is that when it comes to our responsibilities to one another as human beings, religion and evolution nowadays are not necessarily on opposite sides of the fence.
  • in the eyes of many conservative Americans today, religion and evolution do not mix. You either accept what the Bible tells us or what Charles Darwin wrote, but not both
  • Contrary to libertarian and Tea Party rhetoric, evolution has made us a powerfully social species, so much so that the essential precondition of human survival is and always has been the individual plus his or her relationships with others.
  • as Matthew D. Lieberman, a social neuroscience researcher at the University of California, Los Angeles, has written: “we think people are built to maximize their own pleasure and minimize their own pain. In reality, we are actually built to overcome our own pleasure and increase our own pain in the service of following society’s norms.”
  • Why then did Rousseau and others make up stories about human history if they didn’t really believe them? The simple answer, at least during the Enlightenment, was that they wanted people to accept their claim that civilized life is based on social conventions, or contracts, drawn up at least figuratively speaking by free, sane and equal human beings — contracts that could and should be extended to cover the moral and working relationships that ought to pertain between rulers and the ruled.
  • Jean-Jacques Rousseau famously declared in “The Social Contract” (1762) that each of us is born free and yet everywhere we are in chains. He did not mean physical chains. He meant social ones. We now know he was dead wrong. Human evolution has made us obligate social creatures. Even if some of us may choose sooner or later to disappear into the woods or sit on a mountaintop in deep meditation, we humans are able to do so only if before such individualistic anti-social resolve we have first been socially nurtured and socially taught survival arts by others. The distinction Rousseau and others tried to draw between “natural liberty, which is bounded only by the strength of the individual” and “civil liberty, which is limited by the general will” is fanciful, not factual.
  • In short, their aims were political, not historical, scientific or religious.
  • what Rousseau and others crafted as arguments in favor of their ideas all had the earmarks of primitive mythology
  • Bronislaw Malinowski argued almost a century ago: “Myth fulfills in primitive culture an indispensable function: it expresses, enhances, and codifies belief, it safeguards and enforces morality, it vouches for the efficiency of ritual and contains practical rules for the guidance of man.”
  • not all myths make good charters for faith and wisdom. The sanctification of the rights of individuals and their liberties today by libertarians and Tea Party conservatives is contrary to our evolved human nature as social animals. There was never a time in history before civil society when we were each totally free to do whatever we elected to do. We have always been social and caring creatures. The thought that it is both rational and natural for each of us to care only for ourselves, our own preservation, and our own achievements is a treacherous fabrication. This is not how we got to be the kind of species we are today.
  • Myths achieve this social function, he observed, by serving as guides, or charters, for moral values, social order and magical belief.
  • Nor is this what the world’s religions would ask us to believe.

Addicted to Distraction - The New York Times - 0 views

  • ONE evening early this summer, I opened a book and found myself reading the same paragraph over and over, a half dozen times before concluding that it was hopeless to continue. I simply couldn’t marshal the necessary focus.
  • All my life, reading books has been a deep and consistent source of pleasure, learning and solace. Now the books I regularly purchased were piling up ever higher on my bedside table, staring at me in silent rebuke.
  • Instead of reading them, I was spending too many hours online,

  • “The net is designed to be an interruption system, a machine geared to dividing attention,” Nicholas Carr explains in his book “The Shallows: What the Internet Is Doing to Our Brains.” “We willingly accept the loss of concentration and focus, the division of Our attention and the fragmentation of Our thoughts, in return for the wealth of compelling or at least diverting information we receive.”
  • Addiction is the relentless pull to a substance or an activity that becomes so compulsive it ultimately interferes with everyday life
  • Denial is any addict’s first defense. No obstacle to recovery is greater than the infinite capacity to rationalize our compulsive behaviors
  • According to one recent survey, the average white-collar worker spends about six hours a day on email.
  • The brain’s craving for novelty, constant stimulation and immediate gratification creates something called a “compulsion loop.” Like lab rats and drug addicts, we need more and more to get the same effect.
  • Endless access to new information also easily overloads our working memory. When we reach cognitive overload, our ability to transfer learning to long-term memory significantly deteriorates.
  • By that definition, nearly everyone I know is addicted in some measure to the Internet. It has arguably replaced work itself as our most socially sanctioned addictio
  • t we humans have a very limited reservoir of will and discipline. We’re far more likely to succeed by trying to change one behavior at a time, ideally at the same time each day, so that it becomes a habit, requiring less and less energy to sustain.
  • Now it was time to detox. I interpreted the traditional second step — belief that a higher power could help restore my sanity — in a more secular way. The higher power became my 30-year-old daughter, who disconnected my phone and laptop from both my email and the Web.
  • During those first few days, I did suffer withdrawal pangs, most of all the hunger to call up Google and search for an answer to some question that arose. But with each passing day offline, I felt more relaxed, less anxious, more able to focus and less hungry for the next shot of instant but short-lived stimulation. What happened to my brain is exactly what I hoped would happen: It began to quiet down.
  • I had brought more than a dozen books of varying difficulty and length on my vacation. I started with short nonfiction, and then moved to longer nonfiction as I began to feel calmer and my focus got stronger. I eventually worked my way up to “The Emperor of All Maladies
  • I am back at work now, and of course I am back online. The Internet isn’t going away, and it will continue to consume a lot of my attention. My aim now is to find the best possible balance between time online and time off
  • I also make it my business now to take on more fully absorbing activities as part of my days. Above all, I’ve kept up reading books, not just because I love them, but also as a continuing attention-building practice.
  • I’ve retained my longtime ritual of deciding the night before on the most important thing I can accomplish the next morning. That’s my first work activity most days, for 60 to 90 minutes without interruption. Afterward, I take a 10- to 15-minute break to quiet my mind and renew my energy.
  • If I have other work during the day that requires sustained focus, I go completely offline for designated periods, repeating my morning ritual. In the evening, when I go up to my bedroom, I nearly always leave my digital devices downstairs.

The Fallacy of the 'I Turned Out Fine' Argument - The New York Times - 0 views

  • Most of the messages centered on one single, repeated theme: “I was smacked as a child and I turned out just fine.”
  • It makes sense, doesn’t it? Many of us think, “If I had something happen to me and nothing went wrong, then surely it’s fine for everyone else.”
  • The “I turned out just fine” argument is popular. It means that based on our personal experience we know what works and what doesn’t.But the argument has fatal flaws.
  • ...12 more annotations...
  • It’s what’s known as an anecdotal fallacy. This fallacy, in simple terms, states that “I’m not negatively affected (as far as I can tell), so it must be O.K. for everyone.
  • We are relying on a sample size of one. Ourselves, or someone we know. And we are applying that result to everyone
  • It relies on a decision-making shortcut known as the availability heuristic. Related to the anecdotal fallacy, it’s where we draw on information that is immediately available to us when we make a judgment call.
  • studies show that the availability heuristic is a cognitive bias that can cloud us from making accurate decisions utilizing all the information available. It blinds us to our own prejudices
  • It dismisses well-substantiated, scientific evidence. To say “I turned out fine” is an arrogant dismissal of an alternative evidence-based view
  • The statement closes off discourse and promotes a single perspective that is oblivious to alternatives that may be more enlightened. Anecdotal evidence often undermines scientific results, to our detriment.
  • It leads to entrenched attitudes.
  • Perhaps an inability to engage with views that run counter to our own suggests that we did not turn out quite so “fine.”
  • Where is the threshold for what constitutes having turned out fine? If it means we avoided prison, we may be setting the bar too low. Gainfully employed and have a family of our own? Still a pretty basic standard
  • It is as reasonable to say “I turned out fine because of this” as it is to say “I turned out fine in spite of this.”
  • To claim that on this basis spanking a child is fine means that we fall victim to anecdote, rely on our availability heuristic (thereby dismissing all broader data to the contrary), dismiss alternate views, fail to learn and progress by engaging with a challenging idea.
  • We expect our children to embrace learning and to progress in their thinking as they grow older. They deserve to expect the same from us.

How Tech Can Turn Doctors Into Clerical Workers - The New York Times - 0 views

  • what I see in my colleague is disillusionment, and it has come too early, and I am seeing too much of it.
  • In America today, the patient in the hospital bed is just the icon, a place holder for the real patient who is not in the bed but in the computer. That virtual entity gets all our attention. Old-fashioned “bedside” rounds conducted by the attending physician too often take place nowhere near the bed but have become “card flip” rounds
  • My young colleague slumping in the chair in my office survived the student years, then three years of internship and residency and is now a full-time practitioner and teacher. The despair I hear comes from being the highest-paid clerical worker in the hospital: For every one hour we spend cumulatively with patients, studies have shown, we spend nearly two hours on our primitive Electronic Health Records, or “E.H.R.s,” and another hour or two during sacred personal time.
  • ...23 more annotations...
  • The living, breathing source of the data and images we juggle, meanwhile, is in the bed and left wondering: Where is everyone? What are they doing? Hello! It’s my body, you know
  • Our $3.4 trillion health care system is responsible for more than a quarter of a million deaths per year because of medical error, the rough equivalent of, say, a jumbo jet’s crashing every day.
  • I can get cash and account details all over America and beyond. Yet I can’t reliably get a patient record from across town, let alone from a hospital in the same state, even if both places use the same brand of E.H.R
  • the leading E.H.R.s were never built with any understanding of the rituals of care or the user experience of physicians or nurses. A clinician will make roughly 4,000 keyboard clicks during a busy 10-hour emergency-room shift
  • In the process, our daily progress notes have become bloated cut-and-paste monsters that are inaccurate and hard to wade through. A half-page, handwritten progress note of the paper era might in a few lines tell you what a physician really thought
  • so much of the E.H.R., but particularly the physical exam it encodes, is a marvel of fiction, because we humans don’t want to leave a check box empty or leave gaps in a template.
  • For a study, my colleagues and I at Stanford solicited anecdotes from physicians nationwide about patients for whom an oversight in the exam (a “miss”) had resulted in real consequences, like diagnostic delay, radiation exposure, therapeutic or surgical misadventure, even death. They were the sorts of things that would leave no trace in the E.H.R. because the recorded exam always seems complete — and yet the omission would be glaring and memorable to other physicians involved in the subsequent care. We got more than 200 such anecdotes.
  • The reason for these errors? Most of them resulted from exams that simply weren’t done as claimed. “Food poisoning” was diagnosed because the strangulated hernia in the groin was overlooked, or patients were sent to the catheterization lab for chest pain because no one saw the shingles rash on the left chest.
  • I worry that such mistakes come because we’ve gotten trapped in the bunker of machine medicine. It is a preventable kind of failure
  • How we salivated at the idea of searchable records, of being able to graph fever trends, or white blood counts, or share records at a keystroke with another institution — “interoperability”
  • The seriously ill patient has entered another kingdom, an alternate universe, a place and a process that is frightening, infantilizing; that patient’s greatest need is both scientific state-of-the-art knowledge and genuine caring from another human being. Caring is expressed in listening, in the time-honored ritual of the skilled bedside exam — reading the body — in touching and looking at where it hurts and ultimately in localizing the disease for patients not on a screen, not on an image, not on a biopsy report, but on their bodies.
  • What if the computer gave the nurse the big picture of who he was both medically and as a person?
  • a professor at M.I.T. whose current interest in biomedical engineering is “bedside informatics,” marvels at the fact that in an I.C.U., a blizzard of monitors from disparate manufacturers display EKG, heart rate, respiratory rate, oxygen saturation, blood pressure, temperature and more, and yet none of this is pulled together, summarized and synthesized anywhere for the clinical staff to use
  • What these monitors do exceedingly well is sound alarms, an average of one alarm every eight minutes, or more than 180 per patient per day. What is our most common response to an alarm? We look for the button to silence the nuisance because, unlike those in a Boeing cockpit, say, our alarms are rarely diagnosing genuine danger.
  • By some estimates, more than 50 percent of physicians in the United States have at least one symptom of burnout, defined as a syndrome of emotional exhaustion, cynicism and decreased efficacy at work
  • It is on the increase, up by 9 percent from 2011 to 2014 in one national study. This is clearly not an individual problem but a systemic one, a 4,000-key-clicks-a-day problem.
  • The E.H.R. is only part of the issue: Other factors include rapid patient turnover, decreased autonomy, merging hospital systems, an aging population, the increasing medical complexity of patients. Even if the E.H.R. is not the sole cause of what ails us, believe me, it has become the symbol of burnou
  • burnout is one of the largest predictors of physician attrition from the work force. The total cost of recruiting a physician can be nearly $90,000, but the lost revenue per physician who leaves is between $500,000 and $1 million, even more in high-paying specialties.
  • I hold out hope that artificial intelligence and machine-learning algorithms will transform our experience, particularly if natural-language processing and video technology allow us to capture what is actually said and done in the exam room.
  • as with any lab test, what A.I. will provide is at best a recommendation that a physician using clinical judgment must decide how to apply.
  • True clinical judgment is more than addressing the avalanche of blood work, imaging and lab tests; it is about using human skills to understand where the patient is in the trajectory of a life and the disease, what the nature of the patient’s family and social circumstances is and how much they want done.
  • Much of that is a result of poorly coordinated care, poor communication, patients falling through the cracks, knowledge not being transferred and so on, but some part of it is surely from failing to listen to the story and diminishing skill in reading the body as a text.
  • As he was nearing death, Avedis Donabedian, a guru of health care metrics, was asked by an interviewer about the commercialization of health care. “The secret of quality,” he replied, “is love.”/•/

The Moral Instinct - The New York Times - 2 views

  • Today, a new field is using illusions to unmask a sixth sense, the moral sense. Moral intuitions are being drawn out of people in the lab, on Web sites and in brain scanners, and are being explained with tools from game theory, neuroscience and evolutionary biology.
  • The other hallmark is that people feel that those who commit immoral acts deserve to be punished
  • If morality is a mere trick of the brain, some may fear, our very grounds for being moral could be eroded. Yet as we shall see, the science of the moral sense can instead be seen as a way to strengthen those grounds, by clarifying what morality is and how it should steer our actions.
  • ...13 more annotations...
  • The starting point for appreciating that there is a distinctive part of our psychology for morality is seeing how moral judgments differ from other kinds of opinions we have on how people ought to behave.
  • Moralization is a psychological state that can be turned on and off like a switch, and when it is on, a distinctive mind-set commandeers our thinking. This is the mind-set that makes us deem actions immoral (“killing is wrong”), rather than merely disagreeable (“I hate brussels sprouts”), unfashionable (“bell-bottoms are out”) or imprudent (“don’t scratch mosquito bites”).
  • The first hallmark of moralization is that the rules it invokes are felt to be universal
  • Many of these moralizations, like the assault on smoking, may be understood as practical tactics to reduce some recently identified harm. But whether an activity flips our mental switches to the “moral” setting isn’t just a matter of how much harm it does
  • We all know what it feels like when the moralization switch flips inside us — the righteous glow, the burning dudgeon, the drive to recruit others to the cause.
  • The human moral sense turns out to be an organ of considerable complexity, with quirks that reflect its evolutionary history and its neurobiological foundations.
  • At the same time, many behaviors have been amoralized, switched from moral failings to lifestyle choices. They include divorce, illegitimacy, being a working mother, marijuana use and homosexuality.
  • This wave of amoralization has led the cultural right to lament that morality itself is under assault, as we see in the group that anointed itself the Moral Majority. In fact there seems to be a Law of Conservation of Moralization, so that as old behaviors are taken out of the moralized column, new ones are added to it.
  • Much of our recent social history, including the culture wars between liberals and conservatives, consists of the moralization or amoralization of particular kinds of behavior.
  • People don’t generally engage in moral reasoning, Haidt argues, but moral rationalization: they begin with the conclusion, coughed up by an unconscious emotion, and then work backward to a plausible justification.
  • When psychologists say “most people” they usually mean “most of the two dozen sophomores who filled out a questionnaire for beer money.” But in this case it means most of the 200,000 people from a hundred countries who shared their intuitions on a Web-based experiment conducted by the psychologists Fiery Cushman and Liane Young and the biologist Marc Hauser. A difference between the acceptability of switch-pulling and man-heaving, and an inability to justify the choice, was found in respondents from Europe, Asia and North and South America; among men and women, blacks and whites, teenagers and octogenarians, Hindus, Muslims, Buddhists, Christians, Jews and atheists; people with elementary-school educations and people with Ph.D.’s.
  • Joshua Greene, a philosopher and cognitive neuroscientist, suggests that evolution equipped people with a revulsion to manhandling an innocent person. This instinct, he suggests, tends to overwhelm any utilitarian calculus that would tot up the lives saved and lost
  • the findings corroborate Greene’s theory that our nonutilitarian intuitions come from the victory of an emotional impulse over a cost-benefit analysis.

You're Not Going to Change Your Mind - The New York Times - 0 views

  • A troubling feature of political disagreement in the United States today is that many issues on which liberals and conservatives hold divergent views are questions not of value but of fact. Is human activity responsible for global warming? Do guns make society safer? Is immigration harmful to the economy? Though undoubtedly complicated, these questions turn on empirical evidence.
  • Unfortunately, people do not always revise their beliefs in light of new information. On the contrary, they often stubbornly maintain their views. Certain disagreements stay entrenched and polarized.
  • A common explanation is confirmation bias
  • ...11 more annotations...
  • the psychological tendency to favor information that confirms our beliefs
  • If this explanation is right, then there is a relatively straightforward solution to political polarization: We need to consciously expose ourselves to evidence that challenges our beliefs to compensate for our inclination to discount it.
  • But what if confirmation bias isn’t the only culprit? It recently struck us that confirmation bias is often conflated with “telling people what they want to hear,” which is actually a distinct phenomenon known as desirability bias, or the tendency to credit information you want to believe.
  • we decided to conduct an experiment that would isolate these biases
  • The results, which we report in a forthcoming paper in the Journal of Experimental Psychology: General, were clear and robust. Those people who received desirable evidence — polls suggesting that their preferred candidate was going to win — took note and incorporated the information into their subsequent belief
  • . In contrast, those people who received undesirable evidence barely changed their belief about which candidate was most likely to win.
  • we observed a general bias toward the desirable evidence.
  • What about confirmation bias? To our surprise, those people who received confirming evidence — polls supporting their prior belief about which candidate was most likely to win — showed no bias in favor of this information.
  • They tended to incorporate this evidence into their subsequent belief to the same extent as those people who had their prior belief disconfirmed. In other words, we observed little to no bias toward the confirming evidence.
  • Our study suggests that political belief polarization may emerge because of peoples’ conflicting desires, not their conflicting beliefs per se
  • This is rather troubling, as it implies that even if we were to escape from our political echo chambers, it wouldn’t help much. Short of changing what people want to believe, we must find other ways to unify our perceptions of reality.

Our Elites Still Don't Get It - The New York Times - 0 views

  • John Bowlby is the father of attachment theory, which explains how humans are formed by relationships early in life, and are given the tools to go out and lead their lives
  • “All of us, from cradle to grave, are happiest when life is organized as a series of excursions, long or short, from the secure base provided by our attachment figures.”
  • The relationships that form you are mostly things you didn’t choose: your family, hometown, ethnic group, religion, nation and genes.
  • ...21 more annotations...
  • The things you do with your life are mostly chosen: your job, spouse and hobbies.
  • At our foundation, we were a society with strong covenantal attachments — to family, community, creed and faith. Then on top of them we built democracy and capitalism that celebrated liberty and individual rights.
  • The deep covenantal institutions gave people the capacity to use their freedom well. The liberal institutions gave them that freedom.
  • This delicate balance — liberal institutions built atop illiberal ones — is now giving way. The big social movements of the past half century were about maximizing freedom of choice. Right-wingers wanted to maximize economic choice and left-wingers lifestyle choice. Anything that smacked of restraint came to seem like a bad thing to be eliminated.
  • We’ll call this worldview — which is all freedom and no covenant — naked liberalism
  • The problem with naked liberalism is that it relies on individuals it cannot create.
  • Naked liberals of right and left assume that if you give people freedom they will use it to care for their neighbors, to have civil conversations, to form opinions after examining the evidence. But if you weaken family, faith, community and any sense of national obligation, where is that social, emotional and moral formation supposed to come from? How will the virtuous habits form?
  • Naked liberalism has made our society an unsteady tree. The branches of individual rights are sprawling, but the roots of common obligation are withering away.
  • Freedom without covenant becomes selfishness. And that’s what we see at the top of society, in our politics and the financial crisis
  • In my experience, most people under 40 get this. They sense the social and moral void at the core and that change has to come at the communal, emotional and moral level.
  • And that’s what we see at the bottom of society — frayed communities, broken families, opiate addiction.
  • Freedom without a unifying national narrative becomes distrust, polarization and permanent political war.
  • covenantal attachments they become fragile. Moreover, if you rob people of their good covenantal attachments, they will grab bad ones.
  • First, they will identify themselves according to race. They will become the racial essentialists you see on left and right
  • Then they resort to tribalism. This is what Donald Trump provides. As Mark S. Weiner writes on the Niskanen Center’s blog, Trump is constantly making friend/enemy distinctions, exploiting liberalism’s thin conception of community and creating toxic communities based on in-group/out-group rivalry.
  • Trump offers people cultural solutions to their alienation problem. As history clearly demonstrates, people will prefer fascism to isolation, authoritarianism to moral anarchy.
  • If we are going to have a decent society we’re going to have to save liberalism from itself. We’re going to have to restore and re-enchant the covenantal relationships that are the foundation for the whole deal. The crucial battleground is cultural and prepolitical.
  • Freedom without connection becomes alienation.
  • Many public intellectuals were trained in the social sciences and take the choosing individual as their mental starting point. They have trouble thinking about our shared social and moral formative institutions and how such institutions could be reconstituted.
  • Congressional Republicans think a successful tax bill will thwart populism. Mainstream Democrats think the alienation problem will go away if we redistribute the crumbs a bit more widely.
  • History is full of examples of nations that built new national narratives, revived family life, restored community bonds and shared moral culture: Britain in the early 19th century, Germany after World War II, America in the Progressive Era. The first step in launching our own revival is understanding that the problem is down in the roots.

The trouble with atheists: a defence of faith | Books | The Guardian - 1 views

  • My daughter has just turned six. Some time over the next year or so, she will discover that her parents are weird. We're weird because we go to church.
  • This means as she gets older there'll be voices telling her what it means, getting louder and louder until by the time she's a teenager they'll be shouting right in her ear. It means that we believe in a load of bronze-age absurdities. That we fetishise pain and suffering. That we advocate wishy-washy niceness. That we're too stupid to understand the irrationality of our creeds. That we build absurdly complex intellectual structures on the marshmallow foundations of a fantasy. That we're savagely judgmental.
  • that's not the bad news. Those are the objections of people who care enough about religion to object to it. Or to rent a set of recreational objections from Richard Dawkins or Christopher Hitchens. As accusations, they may be a hodge-podge, but at least they assume there's a thing called religion which looms with enough definition and significance to be detested.
  • ...25 more annotations...
  • the really painful message our daughter will receive is that we're embarrassing. For most people who aren't New Atheists, or old atheists, and have no passion invested in the subject, either negative or positive, believers aren't weird because we're wicked. We're weird because we're inexplicable; because, when there's no necessity for it that anyone sensible can see, we've committed ourselves to a set of awkward and absurd attitudes that obtrude, that stick out against the background of modern life, and not in some important or respectworthy or principled way, either.
  • Believers are people who try to insert Jee-zus into conversations at parties; who put themselves down, with writhings of unease, for perfectly normal human behaviour; who are constantly trying to create a solemn hush that invites a fart, a hiccup, a bit of subversion. Believers are people who, on the rare occasions when you have to listen to them, like at a funeral or a wedding, seize the opportunity to pour the liquidised content of a primary-school nativity play into your earhole, apparently not noticing that childhood is over.
  • What goes on inside believers is mysterious. So far as it can be guessed at it appears to be a kind of anxious pretending, a kind of continual, nervous resistance to reality.
  • to me, it's belief that involves the most uncompromising attention to the nature of things of which you are capable. Belief demands that you dispense with illusion after illusion, while contemporary common sense requires continual, fluffy pretending – pretending that might as well be systematic, it's so thoroughly incentivised by our culture.
  • The atheist bus says: "There's probably no God. So stop worrying and enjoy your life."
  • the word that offends against realism here is "enjoy". I'm sorry – enjoy your life?
  • If you based your knowledge of the human species exclusively on adverts, you'd think that the normal condition of humanity was to be a good-looking single person between 20 and 35, with excellent muscle-definition and/or an excellent figure, and a large disposable income. And you'd think the same thing if you got your information exclusively from the atheist bus
  • The implication of the bus slogan is that enjoyment would be your natural state if you weren't being "worried" by us believers and our hellfire preaching. Take away the malignant threat of God-talk, and you would revert to continuous pleasure
  • What's so wrong with this, apart from it being total bollocks? Well, in the first place, that it buys a bill of goods, sight unseen, from modern marketing. Given that human life isn't and can't be made up of enjoyment, it is in effect accepting a picture of human life in which those pieces of living where easy enjoyment is more likely become the only pieces that are visible.
  • But then, like every human being, I am not in the habit of entertaining only those emotions I can prove. I'd be an unrecognisable oddity if I did. Emotions can certainly be misleading: they can fool you into believing stuff that is definitely, demonstrably untrue. Yet emotions are also our indispensable tool for navigating, for feeling our way through, the much larger domain of stuff that isn't susceptible to proof or disproof, that isn't checkable against the physical universe. We dream, hope, wonder, sorrow, rage, grieve, delight, surmise, joke, detest; we form such unprovable conjectures as novels or clarinet concertos; we imagine. And religion is just a part of that, in one sense. It's just one form of imagining, absolutely functional, absolutely human-normal. It would seem perverse, on the face of it, to propose that this one particular manifestation of imagining should be treated as outrageous, should be excised if (which is doubtful) we can manage it.
  • suppose, as the atheist bus goes by, you are povertystricken, or desperate for a job, or a drug addict, or social services have just taken away your child. The bus tells you that there's probably no God so you should stop worrying and enjoy your life, and now the slogan is not just bitterly inappropriate in mood. What it means, if it's true, is that anyone who isn't enjoying themselves is entirely on their own. What the bus says is: there's no help coming.
  • Enjoyment is great. The more enjoyment the better. But enjoyment is one emotion. To say that life is to be enjoyed (just enjoyed) is like saying that mountains should only have summits, or that all colours should be purple, or that all plays should be by Shakespeare. This really is a bizarre category error.
  • A consolation you could believe in would be one that wasn't in danger of popping like a soap bubble on contact with the ordinary truths about us. A consolation you could trust would be one that acknowledged the difficult stuff rather than being in flight from it, and then found you grounds for hope in spite of it, or even because of it
  • The novelist Richard Powers has written that the Clarinet Concerto sounds the way mercy would sound, and that's exactly how I experienced it in 1997. Mercy, though, is one of those words that now requires definition. It does not only mean some tyrant's capacity to suspend a punishment he has himself inflicted. It can mean – and does mean in this case – getting something kind instead of the sensible consequences of an action, or as well as the sensible consequences of an action.
  • from outside, belief looks like a series of ideas about the nature of the universe for which a truth-claim is being made, a set of propositions that you sign up to; and when actual believers don't talk about their belief in this way, it looks like slipperiness, like a maddening evasion of the issue.
  • I am a fairly orthodox Christian. Every Sunday I say and do my best to mean the whole of the Creed, which is a series of propositions. But it is still a mistake to suppose that it is assent to the propositions that makes you a believer. It is the feelings that are primary. I assent to the ideas because I have the feelings; I don't have the feelings because I've assented to the ideas.
  • what I felt listening to Mozart in 1997 is not some wishy-washy metaphor for an idea I believe in, and it's not a front behind which the real business of belief is going on: it's the thing itself. My belief is made of, built up from, sustained by, emotions like that. That's what makes it real.
  • I think that Mozart, two centuries earlier, had succeeded in creating a beautiful and accurate report of an aspect of reality. I think that the reason reality is that way – that it is in some ultimate sense merciful as well as being a set of physical processes all running along on their own without hope of appeal, all the way up from quantum mechanics to the relative velocity of galaxies by way of "blundering, low and horridly cruel" biology (Darwin) – is that the universe is sustained by a continual and infinitely patient act of love. I think that love keeps it in being.
  • That's what I think. But it's all secondary. It all comes limping along behind my emotional assurance that there was mercy, and I felt it. And so the argument about whether the ideas are true or not, which is the argument that people mostly expect to have about religion, is also secondary for me.
  • No, I can't prove it. I don't know that any of it is true. I don't know if there's a God. (And neither do you, and neither does Professor Dawkins, and neither does anybody. It isn't the kind of thing you can know. It isn't a knowable item.)
  • let's be clear about the emotional logic of the bus's message. It amounts to a denial of hope or consolation on any but the most chirpy, squeaky, bubble-gummy reading of the human situation
  • It's got itself established in our culture, relatively recently, that the emotions involved in religious belief must be different from the ones involved in all the other kinds of continuous imagining, hoping, dreaming, and so on, that humans do. These emotions must be alien, freakish, sad, embarrassing, humiliating, immature, pathetic. These emotions must be quite separate from commonsensical us. But they aren't
  • The emotions that sustain religious belief are all, in fact, deeply ordinary and deeply recognisable to anybody who has ever made their way across the common ground of human experience as an adult.
  • It's just that the emotions in question are rarely talked about apart from their rationalisation into ideas. This is what I have tried to do in my new book, Unapologetic.
  • You can easily look up what Christians believe in. You can read any number of defences of Christian ideas. This, however, is a defence of Christian emotions – of their intelligibility, of their grown-up dignity.

How History Gets Things Wrong: The Neuroscience of Our Addiction to Stories | Reviews | Notre Dame Philosophical Reviews | University of Notre Dame - 1 views

  • In this book, Rosenberg elaborates further such arguments to take issue with historical narratives and, more generally, with the way in which we most pervasively make sense of people's actions and motivations through narratives.
  • His main contention is that such narratives are always wrong or, to put it differently, that they can't possibly be right.
  • Rosenberg argues that neuroscience itself, our only reliable method to study psychological capacities, shows that theory of mind's posits do not exist
  • ...12 more annotations...
  • The reason is that the best available evidence on how the brain works shows that the brain does not deal with the kind of things that beliefs and desires are supposed to trade with: contents.
  • When we believe or desire, something is believed or desired: that I have bread, that it rains, that the Parliament passes the bill, etc. Beliefs and desires are about something.
  • . After being presented with the assassin and the crime, the book moves on to explain why, even if always wrong, narratives in general, and historical narratives in particular, are so compelling for us. Even if we have no claim to truth or correctness for our narratives, narratives seem to be highly convincing in moving us to act
  • Furthermore, we cannot but think in terms of them. Rosenberg's explanation for this 'addiction to stories' is that it has been entrenched in us by evolutionary processes that took place over the last million years of natural history
  • Narrative explanations emerged out of Darwinian processes of natural selection -- or "environmental filtration", in the less purposive parlance Rosenberg prefers -- that allowed our ancestors to coordinate efforts, collaborate and flourish, moving from the bottom to the top of the Pleistocene's food chain. Rosenberg argues that while the basic mechanisms of mindreading pervasive in the animal kingdom, based on mutual tracking and monitoring of animals' behavior, are a sound method for getting agents to coordinate behavior, these mechanisms' more recent successor, the theory of mind, crafted by the use of co-evolved languages, turned those mindreading abilities into a theory with empirical hypothesis about agents' beliefs and desires but no facts to match them.
  • The error historians allegedly make lies in mistaking stories for real explanations, surmising that behind our behavior there are purposes, rational motivations.
  • Historians -- in particular narrative historians -- make a pervasive use of folk psychological explanations, i.e., explanations that describe events in terms of the beliefs and desires of historical agents, including individuals and groups.
  • In order for folk psychological and historical narratives to be right there have to be facts of the matter about what sentences in such explanation refer to that make them true.
  • Folk psychological explanations of actions in terms of platitudes about beliefs and desires pairings evolved in natural history closely related to mind-reading mechanisms that allowed our ancestors to deal with cooperation and coordination problems.
  • There are no interpretative mechanisms in the brain (at any level of description) that can vindicate the attribution of contents to beliefs and desires.
  • There are no facts of the matter that allow us to select belief/desire pairings as those actually operating 'behind' an agent's behavior.
  • Folk psychological explanations do not track any facts and thus can't be correct.

6 Ways Social Media Affects Our Mental Health - 0 views

  • But possibly as concerning is the thing that we often do while we're sitting: Mindlessly scrolling through our social media feeds when we have a few spare minutes (or for some, hours)
  • It’s addictive
  • Experts have not been in total agreement on whether internet addiction is a real thing, let alone social media addiction, but there’s some good evidence that both may exist.
  • ...14 more annotations...
  • And studies have confirmed that people tend to undergo a kind of withdrawal: A study a few years ago from Swansea University found that people experienced the psychological symptoms of withdrawal when they stopped using (this went for all internet use, not just social media).
  • It triggers more sadness, less well-being
  • The more we use social media, the less happy we seem to be. One study a few years ago found that Facebook use was linked to both less moment-to-moment happiness and less life satisfaction—the more people used Facebook in a day, the more these two variables dropped off
  • In fact, another study found that social media use is linked to greater feelings of social isolation.
  • Comparing our lives with others is mentally unhealthy
  • One study looked at how we make comparisons to others posts, in “upward” or “downward” directions—that is, feeling that we’re either better or worse off than our friends.
  • It can lead to jealousy—and a vicious cycle
  • Studies have certainly shown that social media use triggers feelings of jealousy. The authors of one study, looking at jealousy and other negative feelings while using Facebook, wrote that “This magnitude of envy incidents taking place on FB alone is astounding, providing evidence that FB offers a breeding ground for invidious feelings."
  • We get caught in the delusion of thinking it will help
  • Part of the unhealthy cycle is that we keep coming back to social media, even though it doesn’t make us feel very good.
  • This is probably because of what’s known as a forecasting error: Like a drug, we think getting a fix will help, but it actually makes us feel worse, which comes down to an error in our ability to predict our own response.
  • More friends on social doesn’t mean you’re more social
  • A couple of years ago, a study found that more friends on social media doesn’t necessarily mean you have a better social life—there seems to be a cap on the number of friends a person’s brain can handle, and it takes actual social interaction (not virtual) to keep up these friendships
  • All of this is not to say that there’s no benefit to social media—obviously it keeps us connected across great distances, and helps us find people we’d lost touch with years ago

Looking inward in an era of 'fake news': Addressing cognitive bias | YLAI Network - 0 views

  • In an era when everyone seems eager to point out instances of “fake news,” it is easy to forget that knowing how we make sense of the news is as important as knowing how to spot incorrect or biased content
  • While the ability to analyze the credibility of a source and the veracity of its content remains an essential and often-discussed aspect of news literacy, it is equally important to understand how we as news consumers engage with and react to the information we find online, in our feeds, and on our apps
  • People process information they receive from the news in the same way they process all information around them — in the shortest, quickest way possible
  • ...11 more annotations...
  • When we consider how we engage with the news, some shortcuts we may want to pay close attention to, and reflect carefully on, are cognitive biases.
  • In fact, without these heuristics, it would be impossible for us to process all the information we receive daily. However, the use of these shortcuts can lead to “blind spots,” or unintentional ways we respond to information that can have negative consequences for how we engage with, digest, and share the information we encounter
  • These shortcuts, also called heuristics, streamline our problem-solving process and help us make relatively quick decisions.
  • Confirmation bias is the tendency to seek out and value information that confirms our pre-existing beliefs while discarding information that proves our ideas wrong.
  • Cognitive biases are best described as glitches in how we process information
  • Echo chamber effect refers to a situation in which we are primarily exposed to information, people, events, and ideas that already align with our point of view.
  • Anchoring bias, also known as “anchoring,” refers to people’s tendency to consider the first piece of information they receive about a topic as the most reliable
  • The framing effect is what happens when we make decisions based on how information is presented or discussed, rather than its actual substance.
  • Fluency heuristic occurs when a piece of information is deemed more valuable because it is easier to process or recall
  • Everyone operates under one or more cognitive biases. So, when searching for and reading the news (or other information), it is important to be aware of how these biases might shape how we make sense of this information.
  • In conclusion, we may not be able to control the content of the news — whether it is fake, reliable, or somewhere in between — but we can learn to be aware of how we respond to it and adjust our evaluations of the news accordingly.

The COVID-19 Paradigm Shift-From Values To Careers To Whole Economies - 0 views

  • “Paradigm shifts arise when the dominant paradigm under which normal science operates is rendered incompatible with new phenomena, facilitating the adoption of a new theory or paradigm.”

  • We are experiencing that now, watching sharing be taken to an entirely new level to manage COVID-19.  
  • With literally everyone working from home and only “seeing” each other on Zoom or Skype, how we look, what we wear, and the usual vanity concerns are out the window.
  • The way women lead was (still) being undervalued and dismissed as “too soft” or second-rate in many powerful circles.
  • Women are the majority force in the healthcare battalions keeping us and our loved ones alive and giving comfort to those who lose their battles in our absence. 
  • There are many more shifts occurring from COVID-19 – from a greater appreciation for nature, to more kindness and compassion, a clearer sense of how we spend our time, to careers and businesses.

Lockdown has affected your memory - here's why - BBC Future - 0 views

  • But in a survey conducted by the Alzheimer’s Society, half of relatives said that their loved ones’ memories had got worse after they began living more isolated lives.   
  • The most obvious factor is isolation. We know that a lack of social contact can affect the brain negatively and that the effect is most serious in those already experiencing memory difficulties.
  • Of course, not everyone has felt lonely during the pandemic, and the results of some studies have shown that levels of loneliness have plateaued over time.
  • ...8 more annotations...
  • Meanwhile, the Office of National Statistics in the UK has found that rates of depression have doubled. Both depression and anxiety are known to have an impact on memory.
  • Although levels of anxiety peaked when lockdown started and have gradually reduced, average levels have remained higher than in usual times, especially in people who are young, living alone, living with children, living on a low income or in urban areas
  • Repetition of stories helps us to consolidate our memories of what happened to us – so-called episodic memories. If we can’t socialise as much, perhaps it’s not surprising that those memories don’t feel as crystal clear as usual.
  • This is all made more difficult by a lack of cues to aid our memories. If you go out to work then your journey, the change of scenery and breaks you take punctuate the day, giving you time points to anchor your memorie
  • Then there’s a general fatigue, which also doesn’t help our memories. Zoom meetings are tiring, some work is much harder from home and holidays are getting cancelled. A lack of routine and anxiety about the pandemic can disturb our sleep. Put all that together – basically we’re consistently tired.
  • So with the combination of fatigue, anxiety, a lack of cues, and fewer social interactions, it’s no wonder that some of us feel our memories are letting us down.
  • The good news is that there are things we can do about it. Going for a walk, especially along unfamiliar streets, will bring your brain back to attention
  • Making sure the weekdays and the weekends are different enough not to merge into one can help with the distortions our new life can have on our perception of time.

The View from Nowhere: Questions and Answers » Pressthink - 2 views

  • In pro journalism, American style, the View from Nowhere is a bid for trust that advertises the viewlessness of the news producer. Frequently it places the journalist between polarized extremes, and calls that neither-nor position “impartial.” Second, it’s a means of defense against a style of criticism that is fully anticipated: charges of bias originating in partisan politics and the two-party system. Third: it’s an attempt to secure a kind of universal legitimacy that is implicitly denied to those who stake out positions or betray a point of view. American journalists have almost a lust for the View from Nowhere because they think it has more authority than any other possible stance.
  • Who gets credit for the phrase, “view from nowhere?” # A. The philosopher Thomas Nagel, who wrote a very important book with that title.
  • Q. What does it say? # A. It says that human beings are, in fact, capable of stepping back from their position to gain an enlarged understanding, which includes the more limited view they had before the step back. Think of the cinema: when the camera pulls back to reveal where a character had been standing and shows us a fuller tableau. To Nagel, objectivity is that kind of motion. We try to “transcend our particular viewpoint and develop an expanded consciousness that takes in the world more fully.” #
  • ...11 more annotations...
  • But there are limits to this motion. We can’t transcend all our starting points. No matter how far it pulls back the camera is still occupying a position. We can’t actually take the “view from nowhere,” but this doesn’t mean that objectivity is a lie or an illusion. our ability to step back and the fact that there are limits to it– both are real. And realism demands that we acknowledge both.
  • Q. So is objectivity a myth… or not? # A. One of the many interesting things Nagel says in that book is that “objectivity is both underrated and overrated, sometimes by the same persons.” It’s underrated by those who scoff at it as a myth. It is overrated by people who think it can replace the view from somewhere or transcend the human subject. It can’t.
  • When MSNBC suspends Keith Olbermann for donating without company permission to candidates he supports– that’s dumb. When NPR forbids its “news analysts” from expressing a view on matters they are empowered to analyze– that’s dumb. When reporters have to “launder” their views by putting them in the mouths of think tank experts: dumb. When editors at the Washington Post decline even to investigate whether the size of rallies on the Mall can be reliably estimated because they want to avoid charges of “leaning one way or the other,” as one of them recently put it, that is dumb. When CNN thinks that, because it’s not MSNBC and it’s not Fox, it’s the only the “real news network” on cable, CNN is being dumb about itself.
  • Let some in the press continue on with the mask of impartiality, which has advantages for cultivating sources and soothing advertisers. Let others experiment with transparency as the basis for trust. When you click on their by-line it takes you to a disclosure page where there is a bio, a kind of mission statement, and a creative attempt to say: here’s where I’m coming from (one example) along with campaign contributions, any affiliations or memberships, and–I’m just speculating now–a list of heroes and villains, or major influences, along with an archive of the work, plus anything else that might assist the user in placing this person on the user’s mattering map.
  • if objectivity means trying to ground truth claims in verifiable facts, I am definitely for that. If it means there’s a “hard” reality out there that exists beyond any of our descriptions of it, sign me up. If objectivity is the requirement to acknowledge what is, regardless of whether we want it to be that way, then I want journalists who can be objective in that sense.
  • If it means trying to see things in that fuller perspective Thomas Nagel talked about–pulling the camera back, revealing our previous position as only one of many–I second the motion. If it means the struggle to get beyond the limited perspective that our experience and upbringing afford us… yeah, we need more of that, not less. I think there is value in acts of description that do not attempt to say whether the thing described is good or bad
  • I think we are in the midst of shift in the system by which trust is sustained in professional journalism. David Weinberger tried to capture it with his phrase: transparency is the new objectivity. My version of that: it’s easier to trust in “here’s where I’m coming from” than the View from Nowhere. These are two different ways of bidding for the confidence of the users.
  • In the newer way, the logic is different. “Look, I’m not going to pretend that I have no view. Instead, I am going to level with you about where I’m coming from on this. So factor that in when you evaluate my report. Because I’ve done the work and this is what I’ve concluded…”
  • it has unearned authority in the American press. If in doing the serious work of journalism–digging, reporting, verification, mastering a beat–you develop a view, expressing that view does not diminish your authority. It may even add to it. The View from Nowhere doesn’t know from this. It also encourages journalists to develop bad habits. Like: criticism from both sides is a sign that you’re doing something right, when you could be doing everything wrong.
  • Who gets credit for the phrase, “view from nowhere?” # A. The philosopher Thomas Nagel, who wrote a very important book with that title.
  • It says that human beings are, in fact, capable of stepping back from their position to gain an enlarged understanding, which includes the more limited view they had before the step back. Think of the cinema: when the camera pulls back to reveal where a character had been standing and shows us a fuller tableau. To Nagel, objectivity is that kind of motion.

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

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

Snapchat to stop promoting Trump after controversial posts - CNN - 0 views

  • In a memo to Snap staff on Sunday, the company's CEO, Evan Spiegel, wrote, "we simply cannot promote accounts in America that are linked to people who incite racial violence, whether they do so on or off our platform. our Discover content platform is a curated platform, where we decide what we promote. We have spoken time and again about working hard to make a positive impact, and we will walk the talk with the content we promote on Snapchat. We may continue to allow divisive people to maintain an account on Snapchat, as long as the content that is published on Snapchat is consistent with our community guidelines, but we will not promote that account or content in any way."
  • "There are plenty of debates to be had about the future of our country and the world. But there is simply no room for debate in our country about the value of human life and the importance of a constant struggle for freedom, equality, and justice. We are standing with all those who stand for peace, love, and justice and we will use our platform to promote good rather than evil."
  • Last week, Twitter for the first time affixed a fact-check label to multiple Trump tweets about mail-in ballots and days later put a warning label on a tweet from Trump about the protest, in which he warned: "when the looting starts, the shooting starts." Facebook chose not to act on identical posts that appeared on its platform.

Why you may not be able to trust your own memories | The Independent - 0 views

  • Why you may not be able to trust your own memories | The Independent
  • Take storytelling for example. When we describe our memories to other people, we use artistic licence to tell the story differently depending on who’s listening.
  • we’re often guilty of changing the facts and adding false details to our memories without even realising.
  • ...6 more annotations...
  • There are countless reasons why tiny mistakes or embellishments might happen each time we recall past events, ranging from what we believe is true or wish were true, to what someone else told us about the event, or what we want that person to think. And whenever these flaws happen, they can have long-term effects on how we’ll recall that memory in the future.
  • We rely on our memories not only for sharing stories with friends or learning from our past experiences, but also for crucial things like creating a sense of personal identity.
  • And we might change the story’s details depending on the listener’s attitudes or political leaning.
  • Research shows that when we describe our memories differently to different audiences it isn’t only the message that changes, but sometimes it’s also the memory itself. This is known as the “audience-tuning effect”.
  • memories can change spontaneously over time, as a product of how, when, and why we access them. In fact, sometimes simply the act of rehearsing a memory can be exactly what makes it susceptible to change. This is known as “retrieval-enhanced suggestibility”.
  • One theory is that rehearsing our memories of past events can temporarily make those memories malleable. In other words, retrieving a memory might be a bit like taking ice-cream out of the freezer and leaving it in direct sunlight for a while. By the time our memory goes back into the freezer, it might have naturally become a little misshapen, especially if someone has meddled with it in the meantime.
