Book Review: 'A New History of Life' by Peter Ward and Joe Kirschvink - WSJ - 0 views

  • I imagine that physicists are similarly deluged with revelations about how to build a perpetual-motion machine or about the hitherto secret truth behind relativity. And so I didn’t view the arrival of “A New History of Life” with great enthusiasm.
  • subtitle breathlessly promises “radical new discoveries about the origins and evolution of life on earth,” while the jacket copy avers that “our current paradigm for understanding the history of life on Earth dates back to Charles Darwin’s time, yet scientific advances of the last few decades have radically reshaped that aging picture.”
  • authors Peter Ward and Joe Kirschvink are genuine scientists—paleontologists, to be exact. And they can write.
  • ...16 more annotations...
  • even genuine scientists are human and as such susceptible to the allure of offering up new paradigms (as the historian of science Thomas Kuhn put it)
  • paleontologist Stephen Jay Gould insisted that his conception of “punctuated equilibria” (a kind of Marxist biology that blurred the lines between evolution and revolution), which he developed along with fellow paleontologist Niles Eldredge, upended the traditional Darwinian understanding of how natural selection works.
  • This notion doesn’t constitute a fundamental departure from plain old evolution by natural selection; it simply italicizes that sometimes the process is comparatively rapid, other times slower.
  • In addition, they have long had a peculiar perspective on evolution, because of the limitations of the fossil record
  • Darwin was a pioneering geologist as well as the greatest of all biologists, and his insights were backgrounded by the key concept of uniformitarianism, as advocated by Charles Lyell, his friend and mentor
  • previously regnant paradigm among geologists had been “catastrophism
  • fossil record was therefore seen as reflecting the creation and extinction of new species by an array of dramatic and “unnatural” dei ex machina.
  • Of late, however, uniformitarianism has been on a losing streak. Catastrophism is back, with a bang . . . or a flood, or a burst of extraterrestrial radiation, or an onslaught of unpleasant, previously submerged chemicals
  • This emphasis on catastrophes is the first of a triad of novelties on which “A New History of Life” is based. The second involves an enhanced role for some common but insufficiently appreciated inorganic molecules, notably carbon dioxide, oxygen and hydrogen sulfide.
  • Life didn’t so much unfold smoothly over hundreds of millions of years as lurch chaotically in response to diverse crises and opportunities: too much oxygen, too little carbon dioxide, too little oxygen, too much carbon dioxide, too hot, too cold
  • So far, so good, except that in their eagerness to emphasize what is new and different, the authors teeter on the verge of the same trap as Gould: exaggerating the novelty of their own ideas.
  • Things begin to unravel when it comes to the third leg of Messrs. Ward and Kirschvink’s purported paradigmatic novelty: a supposed role for ecosystems—rain forests, deserts, rivers, coral reefs, deep-sea vents—as units of evolutionary change
  • “While the history of life may be populated by species,” they write, “it has been the evolution of ecosystems that has been the most influential factor in arriving at the modern-day assemblage of life. . . . [W]e know that on occasion in the deep past entirely new ecosystems appear, populated by new kinds of life.” True enough, but it is those “new kinds of life,” not whole ecosystems, upon which natural selection acts.
  • One of the most common popular misconceptions about evolution is that it proceeds “for the good of the species.”
  • The problem is that smaller, nimbler units are far more likely to reproduce differentially than are larger, clumsier, more heterogeneous ones. Insofar as ecosystems are consequential for evolution—and doubtless they are—it is because, like occasional catastrophes, they provide the immediate environment within which something not-so-new is acted out.
  • This is natural selection doing its same-old, same-old thing: acting by a statistically potent process of variation combined with selective retention and differential reproduction, a process that necessarily operates within the particular ecosystem that a given lineage occupies.

Pain Really Is All In Your Head And Emotion Controls Intensity | WFSU - 0 views

  • When you whack yourself with a hammer, it feels like the pain is in your thumb. But really it's in your brain.
  • perception of pain is shaped by brain circuits that are constantly filtering the information coming from our sensory nerves,

  • Despite his injuries, Turner began giving first aid and pulled other soldiers to safety. As he worked, he was shot twice — one bullet breaking a bone in his arm. Yet Turner would say later that he felt almost no pain.
  • "Soldiers in the heat of the moment don't recognize the pain that's happening," Linden says. But once that moment is over, those same soldiers may feel a lot of pain from something minor, like a hypodermic needle, he says.
  • CIA interrogators used both tactics after Sept. 11, according to a Senate report released late last year.
  • One system determines the pain's location, intensity and characteristics: stabbing, aching, burning, etc.
  • there is a completely separate system for the emotional aspect of pain
  • positive emotions — like feeling calm and safe and connected to others — can minimize pain. But negative emotions tend to have the opposite effect. Torturers have exploited that aspect for centuries.
  • they want to accentuate pain during torture they can do this with humiliation [or] with an unpredictable schedule of delivering pain
  • Those things will make the emotional component of the pain experience stronger."
  • brain also determines the emotion we attach to each painful experience, Linden says. That's possible, he explains, because the brain uses two different systems to process pain information coming from our nerve endings.
  • One thing scientists are still trying to understand is precisely how the brain regulates the perception of pain
  • The team studied low-frequency brain waves in a part of the brain that responds to sensations in the hand,
  • Earlier research had shown that these rhythms increase when the brain is blocking sensory information from the hand.
  • reseasrchers monitored the brain waves of a dozen people who were asked to pay attention only to their hand or only to their foot. During the experiment the scientists delivered a light tap to each person's finger or toe.
  • ocused on their feet, low-frequency rhythms increased in the brain area that responds to hand sensations — because participants were asking their brains to ignore sensory input from the hand, and it's these low-frequency rhythms that do the blocking of such information.
  • low-frequency rhythms also increased in a different brain area — the region that ignores distractions, the team discovered.
  • The two areas became synchronized
  • "There's coordination between the front part of the brain, which is the executive control region of the brain, and the sensory part of the brain, which is filtering information from the environment," she says.
  • suggests that at least some people can teach their brains how to filter out things like chronic pain, perhaps through meditation
  • It found that people who practiced mindfulness meditation for eight weeks greatly improved their control of the brain rhythms that block out pain.

Climate activism is doomed if it remains a left-only issue | Jonathan Freedland | Comme... - 0 views

  • When candid, news editors and TV producers admit they presume their audience files climate change under “worthy but dull”. They know they should care, but they struggle.
  • For the media, climate change is Kryptonite. It fails to tick almost every one of the boxes that defines a story. For one thing, it’s not new: it’s a perennial part of the background noise of 21st-century life.
  • Cognitive psychologists speak of “loss aversion”: when presented with a choice between a relatively small sacrifice now and an uncertain but larger loss a generation from now, human beings rarely make the apparently obvious and rational move, to make the sacrifice. Add to that our “optimism bias”: the tendency to assume that all will be well in the end – that “they” will think of some whizzy technical fix to keep the world’s temperature stable, and humanity will dodge the bullet.

  • First, campaigners have to present their case as a simple, compelling story that everyone can understand. This argument, like any political argument, won’t be won with data and graphs but with a narrative. It has to address our hearts, not our heads.
  • Next, the case for the climate has to be at least as much about remedy as diagnosis.
  • But that still leaves what may be the largest political challenge. Right now, climate change has become an issue of the left.
  • In the US, climate scepticism has become one of the defining traits of the right, a more reliable marker even than attitudes to abortion or gun control.

The Brain Science of Keeping Resolutions - 0 views

  • After one month, only about 64 percent of resolutions are still in force and by six months that number drops to less than 50 percent.
  • In a previous post, we explored applications of neuroscience to change management and consulting. One of the key points in that article is that our brain is structured with one primary purpose: to keep us alive so that we can transmit our genes to the next generation.
  • Historically, change has often been dangerous. So we have become hard-wired to avoid and resist it at every turn.

  • One interesting conclusion of his studies is that a healthy brain is much better equipped to make positive changes and stick to them.
  • The discovery of brain plasticity has proven that you can help people change their brains almost immediately, by providing an environment to support learning
  • Even a few drinks a week can reduce overall brain function and create areas of reduced brain function.
  • brain learns better when it is healthy, adopting a healthier lifestyle can help learners develop brains that are more receptive to change and new ideas.
  • Prolonged exposure to high blood pressure not only restricts blood flow to the brain, but increase the risk of dementia, heart attack and stroke.
  • a physical pattern, in the form of neural connections, is formed in the brain. Every time we go over this pattern by revisiting this thought, we make the behavior stronger.
  • Brains with a high degree of new activity tend to stay that way. Brains that are slow to learn new things gradually lose some of their ability to change.
  • In our sleep-deprived world, the average adult is walking around in a brain-induced fog. The brain uses sleep to rebuild and reorganize. Sleep deprivation can result in lower brain performance and less ability to change.

The Creative Climate - NYTimes.com - 0 views

  • Sometimes creativity happens in pairs, duos like Lennon and McCartney who bring clashing worldviews but similar tastes. But sometimes it happens in one person, in someone who contains contradictions and who works furiously to resolve the tensions within.
  • When you see creative people like that, you see that they don’t flee from the contradictions; they embrace dialectics and dualism. They cultivate what Roger Martin called the opposable mind — the ability to hold two opposing ideas at the same time.
  • If they are religious, they seek to live among the secular. If they are intellectual, they go off into the hurly-burly of business and politics. Creative people often want to be strangers in a strange land. They want to live in dissimilar environments to maximize the creative tensions between different parts of themselves.

Why Teenagers Act Crazy - NYTimes.com - 1 views

  • there is a darker side to adolescence that, until now, was poorly understood: a surge during teenage years in anxiety and fearfulness. Largely because of a quirk of brain development, adolescents, on average, experience more anxiety and fear and have a harder time learning how not to be afraid than either children or adults.
  • the brain circuit for processing fear — the amygdala — is precocious and develops way ahead of the prefrontal cortex, the seat of reasoning and executive control. This means that adolescents have a brain that is wired with an enhanced capacity for fear and anxiety, but is relatively underdeveloped when it comes to calm reasoning.
  • the brain’s reward center, just like its fear circuit, matures earlier than the prefrontal cortex. That reward center drives much of teenagers’ risky behavior. This behavioral paradox also helps explain why adolescents are particularly prone to injury and trauma. The top three killers of teenagers are accidents, homicide and suicide.
  • ...10 more annotations...
  • The brain-development lag has huge implications for how we think about anxiety and how we treat it. It suggests that anxious adolescents may not be very responsive to psychotherapy that attempts to teach them to be unafraid, like cognitive behavior therapy
  • should also make us think twice — and then some — about the ever rising use of stimulants in young people, because these drugs may worsen anxiety and make it harder for teenagers to do what they are developmentally supposed to do: learn to be unafraid when it is appropriate
  • up to 20 percent of adolescents in the United States experience a diagnosable anxiety disorder, like generalized anxiety or panic attacks, probably resulting from a mix of genetic factors and environmental influences.
  • This isn’t to say that cognitive therapy is ineffective for teenagers, but that because of their relative difficulty in learning to be unafraid, it may not be the most effective treatment when used on its own.
  • Fear learning lies at the heart of anxiety and anxiety disorders. This primitive form of learning allows us to form associations between events and specific cues and environments that may predict danger.
  • once previously threatening cues or situations become safe, we have to be able to re-evaluate them and suppress our learned fear associations. People with anxiety disorders have trouble doing this and experience persistent fear in the absence of threat — better known as anxiety.
  • Dr. Casey discovered that adolescents had a much harder time “unlearning” the link between the colored square and the noise than children or adults did.
  • adolescents had trouble learning that a cue that was previously linked to something aversive was now neutral and “safe.” If you consider that adolescence is a time of exploration when young people develop greater autonomy, an enhanced capacity for fear and a more tenacious memory for threatening situations are adaptive and would confer survival advantage. In fact, the developmental gap between the amygdala and the prefrontal cortex that is described in humans has been found across mammalian species, suggesting that this is an evolutionary advantage.
  • As a psychiatrist, I’ve treated many adults with various anxiety disorders, nearly all of whom trace the origin of the problem to their teenage years. They typically report an uneventful childhood rudely interrupted by adolescent anxiety. For many, the anxiety was inexplicable and came out of nowhere.
  • prescription sales for stimulants increased more than fivefold between 2002 and 2012. This is of potential concern because it is well known from both human and animal studies that stimulants enhance learning and, in particular, fear conditioning.

Baseball or Soccer? - NYTimes.com - 1 views

  • Baseball is a team sport, but it is basically an accumulation of individual activities. Throwing a strike, hitting a line drive or fielding a grounder is primarily an individual achievement. The team that performs the most individual tasks well will probably win the game.
  • In soccer, almost no task, except the penalty kick and a few others, is intrinsically individual. Soccer, as Simon Critchley pointed out recently in The New York Review of Books, is a game about occupying and controlling space. If you get the ball and your teammates have run the right formations, and structured the space around you, you’ll have three or four options on where to distribute it. If the defenders have structured their formations to control the space, then you will have no options. Even the act of touching the ball is not primarily defined by the man who is touching it; it is defined by the context created by all the other players.
  • Most of us spend our days thinking we are playing baseball, but we are really playing soccer. We think we individually choose what career path to take, whom to socialize with, what views to hold. But, in fact, those decisions are shaped by the networks of people around us more than we dare recognize.
  • ...9 more annotations...
  • “Soccer is a collective game, a team game, and everyone has to play the part which has been assigned to them, which means they have to understand it spatially, positionally and intelligently and make it effective.”
  • Then there is the structure of your network. There is by now a vast body of research on how differently people behave depending on the structure of the social networks. People with vast numbers of acquaintances have more job opportunities than people with fewer but deeper friendships
  • This influence happens through at least three avenues. First there is contagion. People absorb memes, ideas and behaviors from each other the way they catch a cold.
  • soccer is like a 90-minute anxiety dream — one of those frustrating dreams when you’re trying to get somewhere but something is always in the way. This is yet another way soccer is like life.
  • Let me simplify it with a classic observation: Each close friend you have brings out a version of yourself that you could not bring out on your own. When your close friend dies, you are not only losing the friend, you are losing the version of your personality that he or she elicited.
  • Once we acknowledge that, in life, we are playing soccer, not baseball, a few things become clear. First, awareness of the landscape of reality is the highest form of wisdom. It’s not raw computational power that matters most; it’s having a sensitive attunement to the widest environment,
  • Second, predictive models will be less useful. Baseball is wonderful for sabermetricians. In each at bat there is a limited range of possible outcomes. Activities like soccer are not as easily renderable statistically, because the relevant spatial structures are harder to quantify
  • Finally, there is the power of the extended mind. There is also a developed body of research on how much our very consciousness is shaped by the people around us.
  • Is life more like baseball, or is it more like soccer?

The Trick to Being More Virtuous - NYTimes.com - 1 views

  • Psychologists study a phenomenon called “moral elevation,” an emotional state that leads us to act virtuously when exposed to the virtue of others. In experiments, participants who are brought face to face with others’ gratitude or giving behavior are more likely to display those virtues themselves.
  • We can be the passive beneficiaries of moral elevation. But we can actively pursue it as well by rejecting bad influences and seeking good ones. We can even create the circumstances for moral elevation ourselves.
  • If we want to grow in virtue, and experience a healthier, more productive political environment, each of us must demand more virtue.
  • ...4 more annotations...
  • We get more of what we signal we want through our dollars, clicks and votes. If our politics are too often poisonous, it is because, as a society, we are demanding too much poison.
  • We should ask ourselves: What will my next click say about my desires? Will the next article about politics I read elevate me? Or will it be a pathogen that provides momentary satisfaction from an eloquent insult to my enemies, but ultimately fuels personal bitterness and increases the climate of acrimony in America?
  • what do we really demand of the politicians we support? Humility, optimism and flexibility? Or do we excuse our own side for its ideological rigidity, preening self-regard and blame-shifting?
  • The next two years are a challenge to our political leaders, yes — but also to us, to demand a climate of moral elevation as opposed to destruction of the other side.

Even on women with incredibly beautiful (by pop culture standards) bodies. It's quite sad because the imagery we're expected to live up to (or approximate) by cultural standards, is illustration.

With unprecedented economic injustice, ecosystems collapsing, war breaking out everywhere, nations going under water, people starving in refugee camps, the keys to life, behavior, and disease being unlocked in the biological sciences . . . this is what we think women should spend their time worrying about? Talk about a poverty of ambition. No more. Won't even look at these demeaning magazines when I get my hair cut. If that's what a woman cares about, I try to tell her to stop wasting her time.

Pesticides Linked to Honeybee Deaths Pose More Risks, European Group Says - NYTimes.com - 0 views

  • An influential European scientific body said on Wednesday that a group of pesticides believed to contribute to mass deaths of honeybees is probably more damaging to ecosystems than previously thought and questioned whether the substances had a place in sustainable agriculture.
  • A growing body of evidence shows that the widespread use of the pesticides “has severe effects on a range of organisms that provide ecosystem services like pollination and natural pest control, as well as on biodiversity,” the report’s authors said.
  • Predatory insects like parasitic wasps and ladybugs provide billions of dollars’ worth of insect control, they noted, and organisms like earthworms contribute billions more through improved soil productivity. All are harmed by the pesticides.
  • ...5 more annotations...
  • The authors were critical of studies of neonicotinoids on bee health that tested the insects’ ability to survive a single exposure to a given quantity of pesticide dust; they noted that the effect of the chemicals is cumulative and irreversible, meaning that repeated sublethal doses will eventually be deadly if a certain threshold is passed.
  • The restrictive approach used by European regulators contrasts with the more lenient stance of United States regulators. In March, American opponents of neonicotinoid use delivered more than four million signatures to the White House calling for stronger action to protect pollinators.
  • critics say the E.P.A.’s interim policy is rife with loopholes, allowing continued use of existing products for approved applications, for example. They also criticized the agency for not halting the approval of some products that are chemically quite similar to neonicotinoids but classified differently for regulatory purposes.
  • Pollination — the transfer of pollen from one flower to another, typically by wind, bug or bird — is essential to the global food supply. An estimated 75 percent of all traded crops, including apples, soybeans and corn, depend on pollination.
  • Neonicotinoids are absorbed by a plant so that the neurotoxic poison spreads throughout its tissues, including the sap, nectar and pollen. Far more deadly to insects than to mammals, they do not discriminate between harmful pests and beneficial pollinators.

The Wisdom Deficit in Schools - The Atlantic - 0 views

  • When I was in high school, I chose to major in English in college because I wanted to be wiser. That’s the word I used. If I ended up making lots of money or writing a book, great; but really, I liked the prospect of being exposed to great thoughts and deep advice, and the opportunity to apply them to my own life in my own clumsy way. I wanted to live more thoughtfully and purposefully
  • Now I’m a veteran English teacher, reflecting on what’s slowly changed at the typical American public high school—and the word wisdom keeps haunting me. I don’t teach it as much anymore, and I wonder who is.
  • how teachers are now being informed by the Common Core State Standards—the controversial math and English benchmarks that have been adopted in most states—and the writers and thought leaders who shape the assessments matched to those standards. It all amounts to an alphabet soup of bureaucratic expectations and what can feel like soul-less instruction. The Smarter Balanced Assessment Consortium—referred to in education circles simply as "SBAC"—is the association that writes a Common Core-aligned assessment used in 25 states
  • ...17 more annotations...
  • The Common Core promotes 10 so-called "College and Career Readiness Anchor Standards" for reading that emphasize technical skills like analyzing, integrating, and delineating a text. But these expectations deal very little with ensuring students are actually appreciating the literature at hand—and say nothing about the personal engagement and life lessons to which my principal was referring
  • Kate Kinsella, an influential author who consults school districts across the country and is considered "a guiding force on the National Advisory Board for the Consortium on Reading Excellence," recently told me to "ditch literature" since "literary fiction is not critical to college success." Kinsella continued, "What’s represented by the standards is the need to analyze texts rather than respond to literature.
  • As a teacher working within this regimented environment, my classroom objectives have had to shift. I used to feel deeply satisfied facilitating a rich classroom discussion on a Shakespearean play; now, I feel proud when my students explicitly acknowledge the aforementioned "anchor standards" and take the initiative to learn these technical skills.
  • But as a man who used to be a high school student interested in pursuing wisdom, I’m almost startled to find myself up late at night, literally studying these anchor standards instead of Hamlet itself.
  • It just feels like a very slow, gradual cultural shift that I don’t even notice except for sudden moments of nostalgia, like remembering a dream out of nowhere
  • I get it: My job is to teach communication, not values, and maybe that’s reasonable. After all, I’m not sure I would want my daughter gaining her wisdom from a randomly selected high-school teacher just because he passed a few writing and literature courses at a state university (which is what I did). My job description has evolved, and I’m fine with that
  • This arrangement, in theory, allows students to read the literature on their own, when they get their own time—and I’m fine with that. But then, where are they getting the time and space to appreciate the deeper lessons of classic literature, to evaluate its truth and appropriately apply it to their own lives?
  • research suggests that a significant majority of teens do not attend church, and youth church attendance has been decreasing over the past few decades. This is fine with me. But then again, where are they getting their wisdom?
  • I’m not talking about my child, or your child. I’m absolutely positive that my daughter will know the difference between Darcy and Wickham before she’s in eighth grade; and it's likely that people who would gravitate toward this story would appreciate this kind of thinking
  • I’m talking about American children in general—kids whose parents work all day, whose fathers left them or whose mothers died
  • even for the parents who do prioritize the humanities in their households, I’m not sure that one generation is actually sharing culturally relevant wisdom with the next one—not if the general community doesn’t even talk about what that wisdom specifically means. Each family can be responsible for teaching wisdom in their own way, and I’m fine with that. But then, does the idea of cultural wisdom get surrendered in the process?
  • Secular wisdom in the public schools seems like it should inherently spring from the literature that’s shaped American culture. And while the students focus on how Whitman’s "purpose shapes the content and style of his text," they’re obviously exposed to the words that describe his leaves of grass.
  • But there is a noticeable deprioritization of literature, and a crumbling consensus regarding the nation’s idea of classic literature. The Common Core requires only Shakespeare, which is puzzling if only for its singularity
  • The country’s disregard for the institutional transfer of cultural wisdom is evident with this single observation: None of the state assessments has a single question about the content of any classic literature. They only test on reading skills
  • But where are the students getting their wisdom?
  • Admittedly, nothing about the Common Core or any modern shifts in teaching philosophies is forbidding me from sharing deeper lessons found in Plato’s cave or Orwell’s Airstrip One. The fine print of the Common-Core guidelines even mentions a few possible titles. But this comes with constant and pervasive language that favors objective analysis over personal engagement.
  • Later, a kid who reminds me of the teenager I was in high school—a boy who is at different times depressed, excited, naive, and curious—asked me why I became an English teacher. I smiled in self-defense, but I was silent again, not knowing what to say anymore.

The Sheltering Campus: Why College Is Not Home - The New York Times - 2 views

  • The college years — a time for important growth in autonomy and the consolidation of adult identity and life goals — have evolved into an extended period of adolescence during which many of today’s students are not saddled with adult responsibilities.
  • For previous generations, college was a decisive break from parental supervision; guidance and support needed to come from peers and from within.
  • In the past two decades, however, continued family contact and dependence, thanks to cellphones, email and social media, has increased significantly — some parents go so far as to help with coursework.

  • At the same time, the rise in protective committees and procedures (like trigger warnings) ensure that students will not be confronted with course materials that might upset them (even classics like Ovid’s “Metamorphoses” and “The Adventures of Huckleberry Finn”).
  • universities like Yale have given in to the implicit notion that they should provide the equivalent of the home environment.
  • But college is a different kind of community than a family, and its primary job is education of the student and adaptation to independent community living.
  • To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process entails “trying on” new ways of thinking about oneself both intellectually and personally, which is possible only if a certain degree of freedom is allowed.
  • While we should provide “safe spaces” within colleges for marginalized groups, we must also make it safe for all community members to express opinions and challenge majority views. Intellectual growth and flexibility are fostered by rigorous debate and questioning.
  • It is not surprising that young people are prone to lash out, particularly when there are sociologic reasons to do so. Our generation rallied around clear issues: the war in Vietnam and governmentally sanctioned discrimination based on race and gender. ISIS, Newtown, a changing economy with fewer good jobs and stable career paths create anxiety without generating a unifying moral vision
  • The encroachment of behavioral guidelines into the social and even intellectual spheres comes at a cost. Every college discussion about community values, social climate and behavior should also include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.

How Walking in Nature Changes the Brain - The New York Times - 0 views

  • Various studies have found that urban dwellers with little access to green spaces have a higher incidence of psychological problems than people living near parks and that city dwellers who visit natural environments have lower levels of stress hormones immediately afterward than people who have not recently been outside.
  • how a visit to a park or other green space might alter mood has been unclear. Does experiencing nature actually change our brains in some way that affects our emotional health?

  • Brooding, which is known among cognitive scientists as morbid rumination, is a mental state familiar to most of us, in which we can’t seem to stop chewing over the ways in which things are wrong with ourselves and our lives. This broken-record fretting is not healthy or helpful. It can be a precursor to depression and is disproportionately common among city dwellers compared with people living outside urban areas, studies show.
  • such rumination also is strongly associated with increased activity in a portion of the brain known as the subgenual prefrontal cortex.
  • gathered 38 healthy, adult city dwellers and asked them to complete a questionnaire to determine their normal level of morbid rumination. The researchers also checked for brain activity in each volunteer’s subgenual prefrontal cortex, using scans that track blood flow through the brain. Greater blood flow to parts of the brain usually signals more activity in those areas.
  • walking along the highway had not soothed people’s minds. Blood flow to their subgenual prefrontal cortex was still high and their broodiness scores were unchanged. But the volunteers who had strolled along the quiet, tree-lined paths showed slight but meaningful improvements in their mental health, according to their scores on the questionnaire. They were not dwelling on the negative aspects of their lives as much as they had been before the walk. They also had less blood flow to the subgenual prefrontal cortex. That portion of their brains were quieter.
  • many questions remain, he said, including how much time in nature is sufficient or ideal for our mental health, as well as what aspects of the natural world are most soothing. Is it the greenery, quiet, sunniness, loamy smells, all of those, or something else that lifts our moods?

BBC - Capital - Busy: A badge of honour or a big lie? - 0 views

  • idea of the “busy trap” to the overwhelming feeling many professionals have at the end of each day and week, overload is a real issue.
  • But what if we’re looking at the issue in the wrong way? What if you could reframe your thinking, feel less busy and perhaps get more done?
  • somewhere along the way we were convinced that being ‘busy’ was good for us

  • “We’re not busy … we’re productive,” he wrote. “And yes, there’s a difference.”
  • “Busy paints a picture of people who are either keeping themselves occupied or who don’t have the time to do other things,” Spurlock explained. “Productive describes an environment rich with goals, personal and professional achievements and wrapped in success, a place where you're actually creating something vs just doing something.”
  • “Personal productivity… is the most important one, as it centres around the time that I make to spend with my family, my friends and doing things that fulfil me as a living person,”
  • Financial productivity is an important one, as these are the projects that create consistent revenue
  • “Being busy has somehow become a badge of honor. The prevailing notion is that if you aren’t super busy, you aren’t important or hard working,”
  • busyness makes you less productive
  • “When we think of a super busy person, we think of a ringing phone, a flood of emails and a schedule that’s bursting at the seams with major projects and side-projects hitting simultaneously,” he wrote. “Such a situation inevitably leads to multi-tasking and interruptions, which are both deadly to productivity.”
  • As Socrates said: Beware the barrenness of a busy life.

The Origins of Religion: How Supernatural Beliefs Evolved - 0 views

  • specifically, why such beliefs even exist in the first place.
  • how early humans interacted with their natural environment
  • All of a sudden, you see the grasses in front of you rustling. What do you do? Do you stop and think about what might be causing the rustling (the wind or a lion, for example), or do you immediately take some kind of action?

  • HADD may have planted the seeds for religious thought.
  • humans started attributing agency to things that really didn't have agency at all.
  • tendency to explain the natural world through the existence of beings with supernatural powers — things like gods, ancestral spirits, goblins and fairies — formed the basis for religious beliefs, according to many cognitive scientists.
  • They started attributing meaning to the actions of things that weren't really acting of their own accord.
  • they started anticipating what other beings' actions might be and planning their own actions accordingly.

The Arithmetic of Compassion - The New York Times - 1 views

  • WE all can relate to the saying “One death is a tragedy; a million deaths is a statistic.” Our sympathy for suffering and loss declines precipitously when we are presented with increasing numbers of victims.
  • studied survivors of the atomic bombs dropped on Hiroshima and Nagasaki and discovered that a condition he labeled “psychic numbing” enabled them to withstand the psychological trauma of this experience.
  • concept of psychic numbing has implications in many other situations, such as our response to information about refugee crises, mass extinctions and climate change. This information can be deadening in its abstractness. We struggle to care when the numbers get big. The poet Zbigniew Herbert called this “the arithmetic of compassion.”

  • How big do the numbers have to be for insensitivity to begin? Not very, it turns out.
  • The image of Aylan lying face down on the beach captivated the world’s attention and even, in short order, resulted in refugee policy changes in countries as far away as the United States. But 14 Syrian children drowned in the Aegean Sea the next day. Did you notice? Did you care?
  • demonstrated that “compassion fade” can occur when an incident involving a single person expands to as few as two people
  • In addition to psychic numbing, there is another psychological disposition at work, called “pseudoinefficacy.”
  • We found that people might be inclined to send money to an individual person in need, but that if they heard that a second person also required aid but could not be helped, they were less inclined to donate to the first person. Meeting that need no longer felt as satisfying. Similarly, when the need for assistance was described as part of a large-scale relief effort, potential donors would experience a demotivating sense of inefficacy arising from the thought that the help they could provide was but “a drop in the bucket.”
  • It seems that we are psychologically wired to help only one person at a time. And we don’t even care to do that if we sense that there are others we cannot help.
  • In addition, we believe that yet another psychological tendency, the “prominence effect,” explains why genuinely well-meaning people (and their governments) so often fail to intervene to prevent genocides and other large-scale abuses. “Prominent” actions or objectives are those that are easily justified, though they may not match our stated social values.
  • Decisions that protect national security or satisfy our attachment to near-term comforts and conveniences are easily justified. Such choices, as Paul Slovic explains in a recent University of Illinois Law Review article, are likely to trump decisions to protect people or the environment, especially when the humans in need or the environmental phenomena in jeopardy (species, habitats, the planet’s climate) are so vast in scale as to seem distant and abstract.
  • argued decades ago, in their book “New World New Mind,” that our minds had failed to keep up with the times — that we were, in a sense, cave men and cave women, struggling to deal with modern problems, like nuclear annihilation, to which our minds were not suited. They called for a “conscious evolution” in how we processed information about the modern world, meaning an intentional change in our cognitive habits.
  • We need to be alert to how psychic numbing, pseudoinefficacy and the prominence effect lead us to act in ways contrary to our values. Doing so can help us to improve our reactions to information about a complex and often upsetting world
