Opinion | Is There Such a Thing as an Authoritarian Voter? - The New York Times - 0 views

  • Jonathan Weiler, a political scientist at the University of North Carolina at Chapel Hill, has spent much of his career studying the appeal of authoritarian figures: politicians who preach xenophobia, beat up on the press and place themselves above the law while extolling “law and order” for everyone else.
  • He is one of many scholars who believe that deep-seated psychological traits help explain voters’ attraction to such leaders. “These days,” he told me, “audiences are more receptive to the idea” than they used to be.
  • “In 2018, the sense of fear and panic — the disorientation about how people who are not like us could see the world the way they do — it’s so elemental,” Mr. Weiler said. “People understand how deeply divided we are, and they are looking for explanations that match the depth of that division.”

  • Moreover, using the child-rearing questionnaire, African-Americans score as far more authoritarian than whites
  • what, exactly, is an “authoritarian” personality? How do you measure it?
  • for more than half a century — social scientists have tried to figure out why some seemingly mild-mannered people gravitate toward a strongman
  • the philosopher (and German refugee) Theodor Adorno collaborated with social scientists at the University of California at Berkeley to investigate why ordinary people supported fascist, anti-Semitic ideology during the war. They used a questionnaire called the F-scale (F is for fascism) and follow-up interviews to analyze the “total personality” of the “potentially antidemocratic individual.”
  • The resulting 1,000-page tome, “The Authoritarian Personality,” published in 1950, found that subjects who scored high on the F-scale disdained the weak and marginalized. They fixated on sexual deviance, embraced conspiracy theories and aligned themselves with domineering leaders “to serve powerful interests and so participate in their power,”
  • “Globalized free trade has shafted American workers and left us looking for a strong male leader, a ‘real man,’” he wrote. “Trump offers exactly what my maladapted unconscious most craves.”
  • one of the F-scale’s prompts: “Obedience and respect for authority are the most important virtues children should learn.” Today’s researchers often diagnose latent authoritarians through a set of questions about preferred traits in children: Would you rather your child be independent or have respect for elders? Have curiosity or good manners? Be self-reliant or obedient? Be well behaved or considerate?
  • a glance at the Christian group Focus on the Family’s “biblical principles for spanking” reminds us that your approach to child rearing is not pre-political; it is shorthand for your stance in the culture wars.
  • “All the social sciences are brought to bear to try to explain all the evil that persists in the world, even though the liberal Enlightenment worldview says that we should be able to perfect things,” said Mr. Strouse, the Trump voter
  • what should have been obvious:
  • “Trump’s electoral strength — and his staying power — have been buoyed, above all, by Americans with authoritarian inclinations,” wrote Matthew MacWilliams, a political consultant who surveyed voters during the 2016 election
  • The child-trait test, then, is a tool to identify white people who are anxious about their decline in status and power.
  • new book, “Prius or Pickup?,” by ditching the charged term “authoritarian.” Instead, they divide people into three temperamental camps: fixed (people who are wary of change and “set in their ways”), fluid (those who are more open to new experiences and people) and mixed (those who are ambivalent).
  • “The term ‘authoritarian’ connotes a fringe perspective, and the perspective we’re describing is far from fringe,” Mr. Weiler said. “It’s central to American public opinion, especially on cultural issues like immigration and race.”
  • Other scholars apply a typology based on the “Big Five” personality traits identified by psychologists in the mid-20th century: extroversion, agreeableness, conscientiousness, neuroticism and openness to experience. (It seems that liberals are open but possibly neurotic, while conservatives are more conscientious.)
  • Historical context matters — it shapes who we are and how we debate politics. “Reason moves slowly,” William English, a political economist at Georgetown, told me. “It’s constituted sociologically, by deep community attachments, things that change over generations.”
  • “it is a deep-seated aspiration of many social scientists — sometimes conscious and sometimes unconscious — to get past wishy-washy culture and belief. Discourses that can’t be scientifically reduced are problematic” for researchers who want to provide “a universal account of behavior.”
  • in our current environment, where polarization is so unyielding, the apparent clarity of psychological and biological explanations becomes seductive
  • Attitudes toward parenting vary across cultures, and for centuries African-Americans have seen the consequences of a social and political hierarchy arrayed against them, so they can hardly be expected to favor it — no matter what they think about child rearing
  • — we know that’s not going to happen. People have wicked tendencies.”
  • as the social scientific portrait of humanity grows more psychological and irrational, it comes closer and closer to approximating the old Adam of traditional Christianity: a fallen, depraved creature, unable to see himself clearly except with the aid of a higher power
  • The conclusions of political scientists should inspire humility rather than hubris. In the end, they have confirmed what so many observers of our species have long suspected: None of us are particularly free or rational creatures.
  • Allen Strouse is not the archetypal Trump voter whom journalists discover in Rust Belt diners. He is a queer Catholic poet and scholar of medieval literature who teaches at the New School in New York City. He voted for Mr. Trump “as a protest against the Democrats’ failures on economic issues,” but the psychological dimensions of his vote intrigue him. “Having studied Freudian analysis, and being in therapy for 10 years, I couldn’t not reflexively ask myself, ‘How does this decision have to do with my psychology?’” he told me.
  • their preoccupation with childhood and “primitive and irrational wishes and fears” have influenced the study of authoritarianism ever since.

How Much Do Our Genes Influence Our Political Beliefs? - NYTimes.com - 1 views

  • Why do so many poor, working-class and lower-middle-class whites — many of them dependent for survival on government programs — vote for Republicans?
  • three psychologists write that “authoritarianism, religiousness and conservatism,” which they call the “traditional moral values triad,” are “substantially influenced by genetic factors.”
  • all three traits are reflections of “a single, underlying tendency,” previously described in one word by Bouchard in a 2006 paper as “traditionalism.” Traditionalists in this sense are defined as “having strict moral standards and child-rearing practices, valuing conventional propriety and reputation, opposing rebelliousness and selfish disregard of others, and valuing religious institutions and practices.”
  • ...9 more annotations...
  • concluded from their study comparing identical and fraternal twins that “the correlation between religious importance and conservatism” is “driven primarily, but usually not exclusively, by genetic factors.” The substantial “genetic component in these relationships suggests that there may be a common underlying predisposition that leads individuals to adopt conservative bedrock social principles and political ideologies while simultaneously feeling the need for religious experiences.”
  • the Democratic Party — supportive of abortion rights, same-sex marriage and the primacy of self-expressive individualism over obligation to family — is irreconcilably alien to a segment of the electorate.
  • If these predispositions are, as Friesen and Ksiazkiewicz argue, to some degree genetically rooted, they may not lend themselves to rational debate and compromise.

  • the outcome of the 19 presidential elections since 1940: Nine Republican victories; 10 for Democrats. In those races, the winner received less than 53 percent of the vote in 10 elections. This equilibrium suggests that political opinion may be less volatile, and more firmly grounded, than is sometimes suspected.
  • “To the extent that my political opinions can be predicted by my genome, or by an identical twin separated from me at birth who grew up halfway across the world,” Pinker writes, “I have reason to question whether those opinions are justifiable by reason or evidence rather than a reflection of my temperament.”
  • “the discovery that political ideologies are partly heritable points our attention to what the common psychological threads of competing ideologies are – namely temperamental differences such as authoritarianism, conscientiousness, and openness to experience, together with intellectual differences such as intelligence. These could help pinpoint some of the common denominators beneath competing ideologies which cut across the particular hot buttons of the particular era.”
  • such research can enhance our understanding of the larger framework within which public discourse and debate shape key outcomes.
  • We need every tool available to increase our understanding of our systems of self-governance and of how we came to be the political animals that we are.

Achievement gaps: Revenge of the tiger mother | The Economist - 2 views

  • WHEN measured in terms of academic achievement, Asian Americans are a successful bunch. Forty-nine percent have a bachelor's degree or higher. This compares favourably against white Americans (30%), African-Americans (19%) and Latinos (13%).
  • Amy Chua, a self-declared "tiger mother" who became famous for promoting the benefits of harsh parenting, would put this down to culture. She has argued that Chinese-American children statistically out-perform their peers because they are pushed harder at home.
  • she ascribes the success of different cultures in America to a "triple package" comprised of a superiority complex, insecurity and good impulse control. In other words, certain groups tell themselves they are better than other groups, but learn that they have to work hard to succeed, and must resist temptation and distraction in proving themselves.

  • sociologists at City University of New York and the University of Michigan, wanted to try to find out why it exists. In a new paper in the journal PNAS, they looked at whether it could be explained by socio-demographic factors (such as family income and parental education), cognitive ability (were these children simply more intelligent?), or work ethic. 
  • socio-demographic factors could not explain the achievement gap between Asians and whites. This is because recently arrived Asian immigrants with little formal education and low incomes have children that do better in school than their white peers.
  • Being brainier isn't the answer either. When the pair looked at cognitive ability as measured by standardised tests, Asian-Americans were not different from their white peers
  •  Instead Dr Hsin and Dr Xie find that the achievement gap can be explained through harder work—as measured by teacher assessments of student work habits and motivation.
  • What might explain harder work? The authors point to the fact Asian-Americans are likely to be immigrants or children of immigrants who, as a group, tend to be more optimistic. These are people who have made a big move in search of better opportunities. Immigration is a "manifestation of that optimism through effort, that you can have a better life"
  • Added to this mix is a general cultural belief among Asian-Americans that achievement comes with effort. We know that children who believe ability is innate are more inclined to give up if something doesn't come naturally. An understanding that success requires hard work—not merely an aptitude—is therefore useful.
  • “Tiger” parenting clearly has its place, but it is not everything, according to this study. Dr Hsin says that Asian-Americans also have some unique social and ethnic capital, such as good access to tutors and social networks that offer information about schools and college-admission routes. They also benefit from positive stereotypes which lead to wider expectations of success.
  • Should Ms Chua’s approach to child-rearing replace the American standard, which seems to emphasise self-esteem over test scores? Not necessarily. The report’s researchers point out that Asian-American children also suffer from poorer self-images and more conflicted relationships with their parents. Dr Hsin wonders if this may be the result of pressure to meet narrowly defined and high standards for success. Children who fail to meet these expectations end up feeling like failures, while those who succeed fail to feel satisfied because they are simply achieving what is expected.

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.

Sex, Morality, and Modernity: Can Immanuel Kant Unite Us? - The Atlantic - 1 views

  • Before I jump back into the conversation about sexual ethics that has unfolded on the Web in recent days, inspired by Emily Witt's n+1 essay "What Do You Desire?" and featuring a fair number of my favorite writers, it's worth saying a few words about why I so value debate on this subject, and my reasons for running through some sex-life hypotheticals near the end of this article.
  • As we think and live, the investment required to understand one another increases. So do the stakes of disagreeing. 18-year-olds on the cusp of leaving home for the first time may disagree profoundly about how best to live and flourish, but the disagreements are abstract. It is easy, at 18, to express profound disagreement with, say, a friend's notions of child-rearing. To do so when he's 28, married, and raising a son or daughter is delicate, and perhaps best avoided
  • I have been speaking of friends. The gulfs that separate strangers can be wider and more difficult to navigate because there is no history of love and mutual goodwill as a foundation for trust. Less investment has been made, so there is less incentive to persevere through the hard parts.

  • I've grown very close to new people whose perspectives are radically different than mine.
  • It floors me: These individuals are all repositories of wisdom. They've gleaned it from experiences I'll never have, assumptions I don't share, and brains wired different than mine. I want to learn what they know.
  • Does that get us anywhere? A little ways, I think.
  • "Are we stuck with a passé traditionalism on one hand, and total laissez-faire on the other?" Is there common ground shared by the orthodox-Christian sexual ethics of a Rod Dreher and those who treat consent as their lodestar?
  • Gobry suggests that Emmanuel Kant provides a framework everyone can and should embrace, wherein consent isn't nearly enough to make a sexual act moral--we must, in addition, treat the people in our sex lives as ends, not means.
  • Here's how Kant put it: "Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end."
  • the disappearance of a default sexual ethic in America and the divergence of our lived experiences means we have more to learn from one another than ever, even as our different choices raise the emotional stakes.
  • Nor does it seem intuitively obvious that a suffering, terminally ill 90-year-old is regarding himself as a means, or an object, if he prefers to end his life with a lethal injection rather than waiting three months in semi-lucid agony for his lungs to slowly shut down and suffocate him. (Kant thought suicide impermissible.) The terminally ill man isn't denigrating his own worth or the preciousness of life or saying it's permissible "any time" it is difficult. He believes ending his life is permissible only because the end is nigh, and the interim affords no opportunity for "living" in anything except a narrow biological sense.
  • It seems to me that, whether we're talking about a three-week college relationship or a 60-year marriage, it is equally possible to treat one's partner as a means or as an end (though I would agree that "treating as means" is more common in hookups than marriage)
  • my simple definition is this: It is wrong to treat human persons in such a way that they are reduced to objects. This says nothing about consent: a person may consent to be used as an object, but it is still wrong to use them that way. It says nothing about utility: society may approve of using some people as objects; whether those people are actual slaves or economically oppressed wage-slaves it is still wrong to treat them like objects. What it says, in fact, is that human beings have intrinsic worth and dignity such that treating them like objects is wrong.
  • what it means to treat someone as a means, or as an object, turns out to be in dispute.
  • Years ago, I interviewed a sister who was acting as a surrogate for a sibling who couldn't carry her own child. The notion that either regarded the other (or themselves) as an object seems preposterous to me. Neither was treating the other as a means, because they both freely chose, desired and worked in concert to achieve the same end.
  • It seems to me that the Kantian insight is exactly the sort of challenge traditionalist Christians should make to college students as they try to persuade them to look more critically at hookup culture. I think a lot of college students casually mislead one another about their intentions and degree of investment, feigning romantic interest when actually they just want to have sex. Some would say they're transgressing against consent. I think Kant has a more powerful challenge. 
  • Ultimately, Kant only gets us a little way in this conversation because, outside the realm of sex, he thinks consent goes a long way toward mitigating the means problem, whereas in the realm of sex, not so much. This is inseparable from notions he has about sex that many of us just don't share.
  • two Biblical passages fit my moral intuition even better than Kant. "Love your neighbor as yourself." And "therefore all things whatsoever would that men should do to you, do ye even so to them.
  • "do unto others..." is extremely demanding, hard to live up to, and a very close fit with my moral intuitions.
  • "Do unto others" is also enough to condemn all sorts of porn, and to share all sorts of common ground with Dreher beyond consent. Interesting that it leaves us with so many disagreements too. "Do unto others" is core to my support for gay marriage.
  • Are our bones always to be trusted?) The sexual behavior parents would be mortified by is highly variable across time and cultures. So how can I regard it as a credible guide of inherent wrong? Professional football and championship boxing are every bit as violent and far more physically damaging to their participants than that basement scene, yet their cultural familiarity is such that most people don't feel them to be morally suspect. Lots of parents are proud, not mortified, when a son makes the NFL.
  • "Porn operates in fantasy the way boxing and football operate in fantasy. The injuries are quite real." He is, as you can see, uncomfortable with both. Forced at gunpoint to choose which of two events could proceed on a given night, an exact replica of the San Francisco porn shoot or an Ultimate Fighting Championship tournament--if I had to shut one down and grant the other permission to proceed--what would the correct choice be?
  • insofar as there is something morally objectionable here, it's that the audience is taking pleasure in the spectacle of someone being abused, whether that abuse is fact or convincing illusion. Violent sports and violent porn interact with dark impulses in humanity, as their producers well know.
  • If Princess Donna was failing to "do unto others" at all, the audience was arguably who she failed. Would she want others to entertain her by stoking her dark human impulses? Then again, perhaps she is helping to neuter and dissipate them in a harmless way. That's one theory of sports, isn't it? We go to war on the gridiron as a replacement for going to war? And the rise in violent porn has seemed to coincide with falling, not rising, incidence of sexual violence. 
  • On all sorts of moral questions I can articulate confident judgments. But I am confident in neither my intellect nor my gut when it comes to judging Princess Donna, or whether others are transgressing against themselves or "nature" when doing things that I myself wouldn't want to do. Without understanding their mindset, why they find that thing desirable, or what it costs them, if anything, I am loath to declare that it's grounded in depravity or inherently immoral just because it triggers my disgust instinct, especially if the people involved articulate a plausible moral code that they are following, and it even passes a widely held standard like "do unto others."
  • Here's another way to put it. Asked to render moral judgments about sexual behaviors, there are some I would readily label as immoral. (Rape is an extreme example. Showing the topless photo your girlfriend sent to your best friend is a milder one.) But I often choose to hold back and error on the side of not rendering a definitive judgment, knowing that occasionally means I'll fail to label as unethical some things that actually turn out to be morally suspect.
  • Partly I take that approach because, unlike Dreher, I don't see any great value or urgency in the condemnations, and unlike Douthat, I worry more about wrongful stigma than lack of rightful stigmas
  • In a society where notions of sexual morality aren't coercively enforced by the church or the state, what purpose is condemnation serving?
  • People are great! Erring on the side of failing to condemn permits at least the possibility of people from all of these world views engaging in conversation with one another.
  • Dreher worries about the fact that, despite our discomfort, neither Witt nor I can bring ourselves to say that the sexual acts performed during the S.F. porn shoot were definitely wrong. Does that really matter? My interlocutors perhaps see a cost more clearly than me, as well they might. My bias is that just arguing around the fire is elevating.

Climatologist Michael E Mann: 'Good people fall victim to doomism. I do too sometimes' ... - 0 views

  • the “inactivists”, as I call them, haven’t given up; they have simply shifted from hard denial to a new array of tactics that I describe in the book as the new climate war.
  • Who is the enemy in the new climate war?It is fossil fuel interests, climate change deniers, conservative media tycoons, working together with petrostate actors like Saudi Arabia and Russia. I call this the coalition of the unwilling.
  • Today Russia uses cyberware – bot armies and trolls – to get climate activists to fight one another and to seed arguments on social media. Russian trolls have attempted to undermine carbon pricing in Canada and Australia, and Russian fingerprints have been detected in the yellow-vest protests in France.
  • ...22 more annotations...
  • I am optimistic about a favourable shift in the political wind. The youth climate movement has galvanised attention and re-centred the debate on intergenerational ethics. We are seeing a tipping point in public consciousness. That bodes well. There is still a viable way forward to avoid climate catastrophe.
  • You can see from the talking points of inactivists that they are really in retreat. Republican pollsters like Frank Luntz have advised clients in the fossil fuel industry and the politicians who carry water for them that you can’t get away with denying climate change any more.
  • Let’s dig into deniers’ tactics. One that you mention is deflection. What are the telltale signs?Any time you are told a problem is your fault because you are not behaving responsibly, there is a good chance that you are being deflected from systemic solutions and policies
  • Blaming the individual is a tried and trusted playbook that we have seen in the past with other industries. In the 1970s, Coca Cola and the beverage industry did this very effectively to convince us we don’t need regulations on waste disposal. Because of that we now have a global plastic crisis. The same tactics are evident in the gun lobby’s motto, “guns don’t kill people, people kill people”, which is classic deflection
  • look at BP, which gave us the world’s first individual carbon footprint calculator. Why did they do that? Because BP wanted us looking at our carbon footprint not theirs.
  • Of course lifestyle changes are necessary but they alone won’t get us where we need to be. They make us more healthy, save money and set a good example for others.
  • But we can’t allow the forces of inaction to convince us these actions alone are the solution and that we don’t need systemic changes
  • I don’t eat meat. We get power from renewable energy. I have a plug-in hybrid vehicle. I do those things and encourage others to do them. but i don’t think it is helpful to shame people people who are not as far along as you.
  • Instead, let’s help everybody to move in that direction. That is what policy and system change is about: creating incentives so even those who don’t think about their environmental footprint are still led in that direction.
  • Another new front in the new climate war is what you call “doomism”. What do you mean by that?Doom-mongering has overtaken denial as a threat and as a tactic. Inactivists know that if people believe there is nothing you can do, they are led down a path of disengagement
  • They unwittingly do the bidding of fossil fuel interests by giving up.What is so pernicious about this is that it seeks to weaponise environmental progressives who would otherwise be on the frontline demanding change. These are folk of good intentions and good will, but they become disillusioned or depressed and they fall into despair.
  • Many of the prominent doomist narratives – [Jonathan] Franzen, David Wallace-Wells, the Deep Adaptation movement – can be traced back to a false notion that an Arctic methane bomb will cause runaway warming and extinguish all life on earth within 10 years. This is completely wrong. There is no science to support that.
  • Good people fall victim to doomism. I do too sometimes. It can be enabling and empowering as long as you don’t get stuck there. It is up to others to help ensure that experience can be cathartic.
  • the entry of new participants. Bill Gates is perhaps the most prominent. His new book, How to Prevent a Climate Disaster, offers a systems analyst approach to the problem, a kind of operating system upgrade for the planet. What do you make of his take?I want to thank him for using his platform to raise awareness of the climate crisis
  • I disagree with him quite sharply on the prescription. His view is overly technocratic and premised on an underestimate of the role that renewable energy can play in decarbonising our civilisation
  • If you understate that potential, you are forced to make other risky choices, such as geoengineering and carbon capture and sequestration. Investment in those unproven options would crowd out investment in better solutions.
  • Gates writes that he doesn’t know the political solution to climate change. But the politics are the problem buddy. If you don’t have a prescription of how to solve that, then you don’t have a solution and perhaps your solution might be taking us down the wrong path.
  • What are the prospects for political change with Joe Biden in the White House?Breathtaking. Biden has surprised even the most ardent climate hawks in the boldness of his first 100 day agenda, which goes well beyond any previous president, including Obama when it comes to use of executive actions. He has incorporated climate policy into every single government agency and we have seen massive investments in renewable energy infrastructure, cuts in subsidies for fossil fuels, and the cancellation of the Keystone XL pipeline.
  • On the international front, the appointment of John Kerry, who helped negotiate the Paris Accord, has telegraphed to the rest of the world that the US is back and ready to lead again
  • That is huge and puts pressure on intransigent state actors like [Australian prime minister] Scott Morrison, who has been a friend of the fossil fuel industry in Australia. Morrison has changed his rhetoric dramatically since Biden became president. I think that creates an opportunity like no other.
  • Have the prospects for that been helped or hindered by Covid?I see a perfect storm of climate opportunity. Terrible as the pandemic has been, this tragedy can also provide lessons, particularly on the importance of listening to the word of science when facing risks
  • Out of this crisis can come a collective reconsideration of our priorities. How to live sustainably on a finite planet with finite space, food and water. A year from now, memories and impacts of coronavirus will still feel painful, but the crisis itself will be in the rear-view mirror thanks to vaccines. What will loom larger will be the greater crisis we face – the climate crisis.

Human Brain: facts and information - 0 views

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

How can Boris Johnson run the UK while suffering from coronavirus? - CNN - 0 views

  • When British Prime Minister Boris Johnson announced on Friday morning that he had tested positive for coronavirus, he insisted that he would continue to head up his country's fight against the pandemic.
  • Isolating the Prime Minister is not that difficult, in itself. The Downing Street premises are actually considerably bigger than they look from the outside.
