The Triumph of Obama's Long Game - 0 views

  • Speaking of ideology versus reality, there is, it seems to me, a parallel on the left. That is the current attempt to deny the profound natural differences between men and women, and to assert, with a straight and usually angry face, that gender is in no way rooted in sex, and that sex is in no way rooted in biology.
  • This unscientific product of misandrist feminism and confused transgenderism is striding through the culture, and close to no one in the elite is prepared to resist it.
  • And so we have the establishment of gender-neutral birth certificates in Canada; and, in England, that lovely old phrase, “Ladies and Gentlemen,” is being removed from announcements on the Tube
  • ...20 more annotations...
  • We have dozens of new pronouns in colleges (for all those genders that have suddenly sprung into existence), and biological males competing in all-female high-school athletic teams (guess who wins at track).
  • Worse, we have constant admonitions against those who actually conform, as most human beings always have, to the general gender rule.
  • We have gone from rightly defending the minority to wrongly problematizing the majority. It should surprise no one that, at some point, the majority will find all of this, as Josh Barro recently explained, “annoying.”
  • I say this as someone happily in the minority — and who believes strongly in the right to subvert or adapt traditional gender roles.
  • But you can’t subvert something that you simultaneously argue doesn’t exist.
  • the core contradiction of ideological transgenderism. By severing the link between sex and gender completely, it abolishes the core natural framework without which the transgender experience makes no sense at all.
  • It’s also a subtle, if unintentional, attack on homosexuality. Most homosexuals are strongly attached to their own gender and attracted to traditional, natural expressions of it. That’s what makes us gay, for heaven’s sake. And that’s one reason the entire notion of a common “LGBT” identity is so misleading. How can a single identity comprise both the abolition of gender and at the same time its celebration?
  • Exceptions, in other words, need a rule to exist. Abolish gender’s roots in biology and sex — and you abolish gay people and transgender people as well.
  • Yes, there’s a range of gender expression among those of the same sex. But it’s still tethered among most to the forces of chromosomes and hormones that make us irreducibly male and female. Nature can be interpreted; it can even be played with; but it cannot be abolished. After all, how can you be “queer” if there is no such thing as “normal”?
  • Transgender people exist and should be treated with absolutely the same human respect, decency, and civil equality as anyone else. But they don’t disprove traditional notions of gender as such — which have existed in all times, places, and cultures in human history and prehistory, and are rooted deeply in evolutionary biology and reproductive strategy.
  • Intersex people exist and, in my view, should not be genitally altered or “fixed” without their adult consent. But they do not somehow negate the overwhelming majority who have no such gender or sexual ambiguity.
  • the entire society does not need to be overhauled in order to make gay or trans experience central to it. Inclusion, yes. Revolution, no.
  • The added problem with this war on nature is the backlash it inevitably incurs. There’s a reason so many working-class men find it hard to vote for Democrats any more. And there’s a reason why a majority of white women last year voted for a man who boasted of sexual assault if the alternative was a triumph for contemporary left-feminism.
  • You can’t assault the core identity of most people’s lives and then expect them to vote for you. As a Trump supporter in Colorado just told a reporter from The New Yorker: “I’ve never been this emotionally invested in a political leader in my life. The more they hate him, the more I want him to succeed. Because what they hate about him is what they hate about me.”
  • One of the features you most associate with creeping authoritarianism is the criminalization of certain political positions. Is anything more anathema to a liberal democracy? If Trump were to suggest it, can you imagine the reaction?
  • And yet it’s apparently fine with a hefty plurality of the Senate and House. I’m referring to the remarkable bill introduced into the Congress earlier this year — with 237 sponsors and co-sponsors in the House and 43 in the Senate — which the ACLU and the Intercept have just brought to light. It’s a remarkably bipartisan effort, backed by Chuck Schumer and Ted Cruz, among many solid Trump-resisting Democrats and hard-line Republicans.
  • it would actually impose civil and criminal penalties on American citizens for backing or joining any international boycott of Israel because of its settlement activities. There are even penalties for simply inquiring about such a boycott. And they’re not messing around. The minimum civil penalty would be $250,000 and the maximum criminal penalty $1 million and 20 years in prison. Up to 20 years in prison for opposing the policies of a foreign government and doing something about it!
  • I’m not in favor of boycotting Israel when we don’t boycott, say, Saudi Arabia. But seriously: making it illegal?
  • Every now and again, you just have to sit back and admire the extraordinary skills of the Greater Israel lobby. You’ve never heard of this bill, and I hadn’t either. But that is partly the point. AIPAC doesn’t want the attention — writers who notice this attempted assault on a free society will be tarred as anti-Semites (go ahead, it wouldn’t be the first time) and politicians who resist it will see their careers suddenly stalled.
  • pointing out this special interest’s distortion of democracy is not the equivalent of bigotry. It’s simply a defense of our democratic way of life.

Less cramming. More Frisbee. At Yale, students learn how to live the good life. - The Washington Post - 0 views

  • Santos designed this class after she realized, as the head of a residential college at Yale, that many students were stressed out and unhappy, grinding through long days that seemed to her far more crushing and joyless than her own college years. Her perception was backed up by statistics
  • a national survey that found nearly half of college students reported overwhelming anxiety and feeling hopeless.
  • “They feel they’re in this crazy rat race, they’re working so hard they can’t take a single hour off — that’s awful.”
  • ...15 more annotations...
  • The idea behind the class is deceptively simple, and many of the lessons — such as gratitude, helping others, getting enough sleep — are familiar.
  • “A lot of people are waking up, realizing that we’re struggling,
  • All semester, hundreds of students tried to rewire themselves — to exercise more, to thank their mothers, to care less about the final grade and more about the ideas.
  • But in ways small and large, silly and heartbreakingly earnest, simple and profound, this class changed the conversation at Yale. It surfaced in late-night talks in dorms, it was dissected in newspaper columns, it popped up, again and again, in memes.
  • It’s the application that’s difficult, a point Santos made repeatedly: Our brains often lead us to bad choices, and even when we realize the choices are bad, it’s hard to break habits.
  • In a way, the class is the very essence of a liberal-arts education: learning, exploration, insight into oneself and the world. But many students described it as entirely unlike any class they had ever taken — nothing to do with academics, and everything to do with life.
  • There’s no longer the same stigma around mental-health issues, he said. “Now, so many people are admitting they want to lead happier lives.”
  • The impact is not limited to Yale. Stories about PSYC157 spread around the world. Santos created a pared-down version of the class and offered it to anyone on the online education site Coursera.
  • She taught students about cognitive biases.
  • “We called it the ways in which our minds suck,” Forti said. “Our minds make us think that certain things make us happy, but they don’t.”
  • Then, they had to apply the lessons
  • There was a palpable difference on campus, several students said, during the week when they performed random acts of kindness.
  • The biggest misconception people have about the class is that Santos is offering some kind of easy happiness fix. “It’s something you have to work on every day. . . . If I keep using these skills, they’ll, over time, help me develop better habits and be happier.
  • So many students have told her the class changed their lives. “If you’re really grateful, show me that,” she told them. “Change the culture.
  • for now students stood and clapped and clapped and clapped, beaming, drowning out even Kanye with their standing ovation. As if they had nothing but time.

Health Facts Aren't Enough. Should Persuasion Become a Priority? - The New York Times - 0 views

  • In a paper published early this year in Nature Human Behavior, scientists asked 500 Americans what they thought about foods that contained genetically modified organisms.
  • The vast majority, more than 90 percent, opposed their use. This belief is in conflict with the consensus of scientists
  • The second finding of the study was more eye-opening. Those who were most opposed to genetically modified foods believed they were the most knowledgeable about this issue, yet scored the lowest on actual tests of scientific knowledge.
  • ...14 more annotations...
  • A small percentage of the public believes that vaccines are truly dangerous. People who hold this view — which is incorrect — also believe that they know more than experts about this topic.
  • the study was also conducted in France and Germany, with similar results.
  • those with the least understanding of science had the most science-opposed views, but thought they knew the most
  • Many Americans take supplements, but the reasons are varied and are not linked to any hard evidence
  • Most of them say they are unaffected by claims from experts contradicting the claims of manufacturers. Only a quarter said they would stop using supplements if experts said they were ineffective. They must think they know better.
  • the Dunning-Kruger effect, named for the two psychologists who wrote a seminal paper in 1999 entitled “Unskilled and Unaware of It.”
  • A lack of knowledge leaves some without the contextual information necessary to recognize mistakes, they wrote, and their “incompetence robs them of the ability to realize it.”
  • communication strategies on G.M.O.s — intended to help the public see that their beliefs did not align with experts — wound up backfiring
  • attempting to provide corrective information to voters about death panels wound up increasing their belief in them among politically knowledgeable supporters of Sarah Palin.
  • A 2015 study published in Vaccine showed that giving corrective information about the flu vaccine led patients most concerned about side effects to be less likely to get the vaccine.
  • “knowledge deficit model,” an idea that the lack of support for good policies, and good science, merely reflects a lack of scientific information.
  • Scientists need to be formally trained in communication skills, they said, and they also need to realize that the knowledge deficit model makes for easy policy, but not necessarily good results.
  • It seems important to engage the public more, and earn their trust through continued, more personal interaction, using many different platforms and technologies
  • Bombarding people with more information about studies isn’t helping. How the information contained in them is disseminated and discussed may be much more important.

Bilingual brain boost: Two tongues, two minds | New Scientist - 0 views

  • Speaking a second language can change everything from problem-solving skills to personality – almost as if you are two people
  • Cognitive enhancement is just the start. According to some studies, my memories, values, even my personality, may change depending on which language I happen to be speaking. It is almost as if the bilingual brain houses two separate minds. All of which highlights the fundamental role of language in human thought
  • The view of bilingualism has not always been this rosy. For many parents like mine, the decision to raise children speaking two languages was controversial. Since at least the 19th century, educators warned that it would confuse the child, making them unable to learn either language properly. At best, they thought the child would become a jack-of-all-trades and master of none. At worst, they suspected it might hinder other aspects of development, resulting in a lower IQ
  • ...5 more annotations...
  • a key study in the 1960s by Elizabeth Peal and Wallace Lambert at McGill University in Montreal, Canada, found that the ability to speak two languages does not stunt overall development. On the contrary, when controlling for other factors which might also affect performance, such as socioeconomic status and education, they found that bilinguals outperformed monolinguals in 15 verbal and non-verbal tests
  • Besides giving us bilinguals a brain boost, speaking a second language may have a profound effect on behaviour. Neuroscientists and psychologists are coming to accept that language is deeply entwined with thought and reasoning, leading some to wonder whether bilingual people act differently depending on which language they are speaking. That would certainly tally with my experience. People often tell me that I seem different when I speak English compared with when I speak French.
  • One explanation is that each language brings to mind the values of the culture we experienced while learning it, says Nairán Ramírez-Esparza, a psychologist at the University of Washington in Seattle. She recently asked bilingual Mexicans to rate their personality in English and Spanish questionnaires. Modesty is valued more highly in Mexico than it is in the US, where assertiveness gains respect, and the language of the questions seemed to trigger these differences. When questioned in Spanish, each volunteer was more humble than when the survey was presented in English
  • Much has been made of the difficulties of learning a new language later in life, but the evidence so far suggests the effort should pay off. “You can learn another language at any age, you can learn it fluently, and you can see benefits to your cognitive system,” says Marian. Bialystok agrees that late language-learners gain an advantage, even if the performance boost is usually less pronounced than in bilingual speakers. “Learn a language at any age, not to become bilingual, but just to remain mentally stimulated,” she says. “That’s the source of cognitive reserve.”
  • As it is, I’m grateful that particular challenge is behind me. My mother could never have guessed the extent to which her words would change my brain and the way I see my world, but I’m certain it was worth the effort. And for all that I just have to say: Merci!

The Simple Economics of Machine Intelligence - 0 views

  • The year 1995 was heralded as the beginning of the “New Economy.” Digital communication was set to upend markets and change everything. But economists by and large didn’t buy into the hype.
  • Today we are seeing similar hype about machine intelligence. But once again, as economists, we believe some simple rules apply. Technological revolutions tend to involve some important activity becoming cheap, like the cost of communication or finding information. Machine intelligence is, in its essence, a prediction technology, so the economic shift will center around a drop in the cost of prediction.
  • The first effect of machine intelligence will be to lower the cost of goods and services that rely on prediction. This matters because prediction is an input to a host of activities including transportation, agriculture, healthcare, energy manufacturing, and retail.
    • douglasn89
       
      This emphasis on prediction ties into the previous discussion and reading we had which included the idea that humans by nature are poor predictors, so because of that, they have begun to design machines to predict.
  • ...4 more annotations...
  • As machine intelligence lowers the cost of prediction, we will begin to use it as an input for things for which we never previously did. As a historical example, consider semiconductors, an area of technological advance that caused a significant drop in the cost of a different input: arithmetic. With semiconductors we could calculate cheaply, so activities for which arithmetic was a key input, such as data analysis and accounting, became much cheaper.
  • As machine intelligence improves, the value of human prediction skills will decrease because machine prediction will provide a cheaper and better substitute for human prediction, just as machines did for arithmetic.
  • Using the language of economics, judgment is a complement to prediction and therefore when the cost of prediction falls demand for judgment rises. We’ll want more human judgment.
  • But it yields two key implications: 1) an expanded role of prediction as an input to more goods and services, and 2) a change in the value of other inputs, driven by the extent to which they are complements to or substitutes for prediction. These changes are coming.

      This article agrees with the readings from Unit 5 Lesson 6 in its prediction of changes.

The Big Problem With the New SAT - NYTimes.com - 1 views

  • AT first glance, the College Board’s revised SAT seems a radical departure from the test’s original focus on students’ general ability or aptitude.
  • The revised SAT takes some important, if partial, steps toward becoming a test of curriculum mastery. In place of the infamously tricky, puzzle-type items, the exam will be a more straightforward test of material that students encounter in the classroom.
  • While a clear improvement, the revised SAT remains problematic. It will still emphasize speed — quick recall and time management — over subject knowledge. Despite evidence that writing is the single most important skill for success in college, the essay will be optional.
  • ...3 more annotations...
  • And the biggest problem is this: While the content will be new, the underlying design will not change. The SAT will remain a “norm-referenced” exam, designed primarily to rank students rather than measure what they actually know.
  • Norm-referenced tests like the SAT and the ACT have contributed enormously to the “educational arms race” — the ferocious competition for admission at top colleges and universities. They do so by exaggerating the importance of small differences in test scores that have only marginal relevance for later success in college. Because of the way such tests are designed, answering even a few more questions correctly can substantially raise students’ scores and thereby their rankings. This creates great pressure on students and their parents to avail themselves of expensive test-prep services in search of any edge. It is also unfair to those who cannot afford such services. Yet research on college admissions has repeatedly confirmed that test scores, as compared to high school grades, are relatively weak predictors of how students actually perform in college.
  • College admissions will never be perfectly fair and rational; the disparities are too deep for that. Yet the process can be fairer and more rational if we rethink the purposes of college-entrance exams.

Research finds college placement tests in need of makeover | Education Dive - 1 views

  • majority of colleges in the United States use a single test to determine what courses incoming students are eligible to take

  • researchers are coalescing around the need to rethink the placement process itself.
  • Some are calling for statewide policy changes, others are pushing individual schools or systems to look at their own practices and improve upon them
  • Nearly 70% of community college students are placed into remedial courses each year. Many of these students are from low-income and minority backgrounds, both of which are still highly underrepresented in science, technology, engineering, and math, or STEM, fields
  • recommend colleges incorporate student goals and motivation into their placement decision and acknowledge the realistic math needs of various degree programs.
  • Yet, placement tests are almost universally skewed to measure how well students know algebra.
  • “The way that math placement is done right now hurts a lot of students.”
  • a key recommendation for colleges is to step up professional development with advisors and help them guide students through appropriate course sequences for their end goals
  • In many places the advisor-to-student ratio is too high to allow for proper guidance
  • Placement tests must evaluate the range of skills, however
  • Single standardized tests are easy to administer and cheap to interpret, but they don’t seem to work for placement

Reed Graduate: Hum 110 Encourages Challenging the Past - The Atlantic - 0 views

  • a worthwhile—and necessary—discussion about whether anyone should read the ancient Greeks in the first place, and if so why and how.
  • As someone who took Hum 110 more than 20 years ago, the news from campus has made me reflect on what I learned in the course. The answers, both equally true, are that I didn’t learn very much—and that I learned everything.
  • I slogged through the Hum 110 readings and wrote the required papers, but I can’t say that the words of Herodotus, Sappho, or Homer really sank in.
  • ...9 more annotations...
  • And yet they did. What I learned in Hum 110 is that so-called Western civilization is a narrative much like any other—except that it happens to affect just about everyone on earth. No matter where we were born or what we look like or what we believe, the narrative of Western civilization is part of the cultural water we swim in. By taking me back to the origins of that narrative, Hum 110 did me the great favor of hauling it into view—and impressing me with the universal right and duty to question it.
  • Members of Reedies Against Racism argue that Hum 110 simply perpetuates the most familiar version of the Western-civilization narrative—that positioning Plato and Aristotle at the very center of the college curriculum helps ensure their continued influence, along with the continued silencing of other voices from the past. This is worth considering
  • To many of the campus protesters, then, the Hum 110 syllabus looks like a monument overdue for toppling; online discussions have even compared it to the Confederate flag.
  • I respect the beauty and boldness and skill displayed in all these texts, and I respect the expertise of those who devote their lives to studying them. But I learned in Hum 110 that to respect a text is to keep experimenting with it, and to keep testing its relevance. Some of these works have already survived thousands of years of scrutiny; let’s see if they can take a few millennia more.
  • In my experience, the Hum 110 syllabus wasn’t a tool of exclusion but a route to inclusion.
  • The syllabus is more diverse, as is the faculty that teaches it and the student body that reads it. This is not to say that the syllabus is perfect—far from it. It’s to say that it isn’t carved in stone—and unlike a monument or a flag, it’s not meant to teach reverence. In fact, Hum 110 is intended to teach precisely the opposite.
  • Not long ago, a friend of mine told me about some classical theater she’d seen. “I enjoyed it,” she said, “but I don’t feel like it’s really mine.” She wasn’t talking about representation, about whether someone who looked or acted like her had appeared on stage. She just felt that despite her smarts, and her multiple graduate degrees, she wasn’t familiar enough with the work to engage with it.
  • But by exposing the roots of the narrative known as Western civilization, Hum 110 opened a door to me that’s never closed.
  • What I really learned in Hum 110 is that the ancient Greeks—and the rest of our collective cultural ancestries, for that matter—are mine. They’re mine and yours and theirs and ours, to honor with our sharpest spears.

History News Network | We Traded in One of the Most Self-Disciplined Presidents for the Most Undisciplined President - 1 views

  • How ironic it is then that President Obama, the bane of conservatives, possessed an abundance of self-discipline, and President Trump, who most conservatives (including Bennet) favored over Hilary Clinton, possesses almost none.
  • The ancient Greek philosopher Aristotle thought that political leaders should exercise practical wisdom (phronesis) or prudence. He considered temperance (i.e., moderation, self-restraint) and self-discipline two of the most important virtues required for such wisdom. He believed that the two virtues should help us regulate what he called “the appetitive faculty,” which deals with our emotions and desires
  • One of the twentieth-century’s most prominent commentators on political wisdom, Britain’s Isaiah Berlin (1909-1997), viewed temperance as an important political virtue, and he connected it to humility and tolerance—neither of which Trump displays. And in his “Two Concepts of Liberty,” Berlin wrote, “Freedom is self-mastery.”
  • ...12 more annotations...
  • Barry Schwartz and Kenneth Sharpe in their Practical Wisdom: The Right Way to Do the Right Thing (2010) state that such wisdom is greatly needed
  • The authors quote Aristotle and give the example of a man practicing practical wisdom and mention that “he had the self-control—the emotion-regulating skills—to choose rightly.”
  • Psychologist, futurist, and editor of The Wisdom Page Tom Lombardo also stresses the importance of temperance and self-control. In his new book on Future Consciousness
  • he includes a whole chapter (of 45 pages) on “Self-Control and Self-Responsibility.” In it he cites favorably two authors who claim that “most human problems are due to a lack of self-control.” He also states that “we cannot flourish without self-responsibility, self-control, and . . . . one of the most unethical forms of thinking and behavior in life . . . is to abdicate self-responsibility and self-control in ourselves.”
  • In Inside Obama’s Brain (2009), journalist Sasha Abramsky talked to over a hundred people who knew Obama and reported that “during the election campaign Obama almost never got upset, or panicked, by day-to-day shifts in momentum, by the ups and downs of opinion polls.” Almost a year into his presidency, Abramsky refered to the president as “a voice of moderation in a corrosively shrill, partisan political milieu.”
  • Up until the end of his presidency, Obama maintained his self-control and temperance. As a Huffington Post piece noted in 2016, he “has been the model of temperance in office on all fronts.”
  • Just as many individuals have commented on Obama’s self-discipline and temperance, so too have many remarked on Trump’s lack of these virtues
  • In May 2017, Brooks stated: “At base, Trump is an infantalist. There are three tasks that most mature adults have sort of figured out by the time they hit 25. Trump has mastered none of them. Immaturity is becoming the dominant note of his presidency, lack of self-control his leitmotif.”
  • Two months later, Douthat opined about Trump: “He is nonetheless clearly impaired, gravely deficient somewhere at the intersection of reason and judgment and conscience and self-control. . . . This president should not be the president, and the sooner he is not, the better.”
  • Karl Rove, a former senior adviser to President George W. Bush, insisted that Trump “lacks the focus or self-discipline to do the basic work required of a president.”
  • At about the same time former Republican senator Tom Coburn (R-OK) declared “The question is, does he have the self-discipline and some control over his ego to be able to say ‘I’m wrong’ every now and then? I haven’t seen that.
  • it is Trump’s narcissism and lack of humility that are his chief faults and hinder him most from being even a mediocre president.

Have Smartphones Destroyed a Generation? - The Atlantic - 0 views

  • She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”
  • The arrival of the smartphone has radically changed every aspect of teenagers’ lives, from the nature of their social interactions to their mental health. These changes have affected young people in every corner of the nation and in every type of household
  • Around 2012, I noticed abrupt shifts in teen behaviors and emotional states. The gentle slopes of the line graphs became steep mountains and sheer cliffs, and many of the distinctive characteristics of the Millennial generation began to disappear. In all my analyses of generational data—some reaching back to the 1930s—I had never seen anything like it.
  • ...54 more annotations...
  • the trends persisted, across several years and a series of national surveys. The changes weren’t just in degree, but in kind.
  • The biggest difference between the Millennials and their predecessors was in how they viewed the world; teens today differ from the Millennials not just in their views but in how they spend their time. The experiences they have every day are radically different from those of the generation that came of age just a few years before them.
  • it was exactly the moment when the proportion of Americans who owned a smartphone surpassed 50 percent.
  • theirs is a generation shaped by the smartphone and by the concomitant rise of social media. I call them iGen
  • Born between 1995 and 2012, members of this generation are growing up with smartphones, have an Instagram account before they start high school, and do not remember a time before the internet.
  • iGen’s oldest members were early adolescents when the iPhone was introduced, in 2007, and high-school students when the iPad entered the scene, in 2010. A 2017 survey of more than 5,000 American teens found that three out of four owned an iPhone.
  • . I had grown accustomed to line graphs of trends that looked like modest hills and valleys. Then I began studying Athena’s generation.
  • More comfortable in their bedrooms than in a car or at a party, today’s teens are physically safer than teens have ever been. They’re markedly less likely to get into a car accident and, having less of a taste for alcohol than their predecessors, are less susceptible to drinking’s attendant ills.
  • Psychologically, however, they are more vulnerable than Millennials were: Rates of teen depression and suicide have skyrocketed since 2011. It’s not an exaggeration to describe iGen as being on the brink of the worst mental-health crisis in decades. Much of this deterioration can be traced to their phones.
  • the twin rise of the smartphone and social media has caused an earthquake of a magnitude we’ve not seen in a very long time, if ever. There is compelling evidence that the devices we’ve placed in young people’s hands are having profound effects on their lives—and making them seriously unhappy.
  • But the allure of independence, so powerful to previous generations, holds less sway over today’s teens, who are less likely to leave the house without their parents. The shift is stunning: 12th-graders in 2015 were going out less often than eighth-graders did as recently as 2009.
  • Today’s teens are also less likely to date. The initial stage of courtship, which Gen Xers called “liking” (as in “Ooh, he likes you!”), kids now call “talking”—an ironic choice for a generation that prefers texting to actual conversation. After two teens have “talked” for a while, they might start dating.
  • only about 56 percent of high-school seniors in 2015 went out on dates; for Boomers and Gen Xers, the number was about 85 percent.
  • The decline in dating tracks with a decline in sexual activity. The drop is the sharpest for ninth-graders, among whom the number of sexually active teens has been cut by almost 40 percent since 1991. The average teen now has had sex for the first time by the spring of 11th grade, a full year later than the average Gen Xer
  • The teen birth rate hit an all-time low in 2016, down 67 percent since its modern peak, in 1991.
  • Nearly all Boomer high-school students had their driver’s license by the spring of their senior year; more than one in four teens today still lack one at the end of high school.
  • In conversation after conversation, teens described getting their license as something to be nagged into by their parents—a notion that would have been unthinkable to previous generations.
  • In the late 1970s, 77 percent of high-school seniors worked for pay during the school year; by the mid-2010s, only 55 percent did. The number of eighth-graders who work for pay has been cut in half.
  • Beginning with Millennials and continuing with iGen, adolescence is contracting again—but only because its onset is being delayed. Across a range of behaviors—drinking, dating, spending time unsupervised— 18-year-olds now act more like 15-year-olds used to, and 15-year-olds more like 13-year-olds. Childhood now stretches well into high school.
  • In an information economy that rewards higher education more than early work history, parents may be inclined to encourage their kids to stay home and study rather than to get a part-time job. Teens, in turn, seem to be content with this homebody arrangement—not because they’re so studious, but because their social life is lived on their phone. They don’t need to leave home to spend time with their friends.
  • eighth-, 10th-, and 12th-graders in the 2010s actually spend less time on homework than Gen X teens did in the early 1990s.
  • The time that seniors spend on activities such as student clubs and sports and exercise has changed little in recent years. Combined with the decline in working for pay, this means iGen teens have more leisure time than Gen X teens did, not less.
  • So what are they doing with all that time? They are on their phone, in their room, alone and often distressed.
  • despite spending far more time under the same roof as their parents, today’s teens can hardly be said to be closer to their mothers and fathers than their predecessors were. “I’ve seen my friends with their families—they don’t talk to them,” Athena told me. “They just say ‘Okay, okay, whatever’ while they’re on their phones. They don’t pay attention to their family.” Like her peers, Athena is an expert at tuning out her parents so she can focus on her phone.
  • The number of teens who get together with their friends nearly every day dropped by more than 40 percent from 2000 to 2015; the decline has been especially steep recently.
  • Eighth-graders who are heavy users of social media increase their risk of depression by 27 percent, while those who play sports, go to religious services, or even do homework more than the average teen cut their risk significantly.
  • The roller rink, the basketball court, the town pool, the local necking spot—they’ve all been replaced by virtual spaces accessed through apps and the web.
  • The results could not be clearer: Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy.
  • There’s not a single exception. All screen activities are linked to less happiness, and all nonscreen activities are linked to more happiness
  • Eighth-graders who spend 10 or more hours a week on social media are 56 percent more likely to say they’re unhappy than those who devote less time to social media
  • If you were going to give advice for a happy adolescence based on this survey, it would be straightforward: Put down the phone, turn off the laptop, and do something—anything—that does not involve a screen
  • Social-networking sites like Facebook promise to connect us to friends. But the portrait of iGen teens emerging from the data is one of a lonely, dislocated generation. Teens who visit social-networking sites every day but see their friends in person less frequently are the most likely to agree with the statements “A lot of times I feel lonely,” “I often feel left out of things,” and “I often wish I had more good friends.” Teens’ feelings of loneliness spiked in 2013 and have remained high since.
  • This doesn’t always mean that, on an individual level, kids who spend more time online are lonelier than kids who spend less time online.
  • Teens who spend more time on social media also spend more time with their friends in person, on average—highly social teens are more social in both venues, and less social teens are less so.
  • The more time teens spend looking at screens, the more likely they are to report symptoms of depression.
  • It’s not only a matter of fewer kids partying; fewer kids are spending time simply hanging out
  • Teens who spend three hours a day or more on electronic devices are 35 percent more likely to have a risk factor for suicide, such as making a suicide plan. (That’s much more than the risk related to, say, watching TV.)
  • Since 2007, the homicide rate among teens has declined, but the suicide rate has increased. As teens have started spending less time together, they have become less likely to kill one another, and more likely to kill themselves. In 2011, for the first time in 24 years, the teen suicide rate was higher than the teen homicide rate.
  • For all their power to link kids day and night, social media also exacerbate the age-old teen concern about being left out.
  • Today’s teens may go to fewer parties and spend less time together in person, but when they do congregate, they document their hangouts relentlessly—on Snapchat, Instagram, Facebook. Those not invited to come along are keenly aware of it. Accordingly, the number of teens who feel left out has reached all-time highs across age groups.
  • Forty-eight percent more girls said they often felt left out in 2015 than in 2010, compared with 27 percent more boys. Girls use social media more often, giving them additional opportunities to feel excluded and lonely when they see their friends or classmates getting together without them.
  • Social media levy a psychic tax on the teen doing the posting as well, as she anxiously awaits the affirmation of comments and likes. When Athena posts pictures to Instagram, she told me, “I’m nervous about what people think and are going to say. It sometimes bugs me when I don’t get a certain amount of likes on a picture.”
  • Girls have also borne the brunt of the rise in depressive symptoms among today’s teens. Boys’ depressive symptoms increased by 21 percent from 2012 to 2015, while girls’ increased by 50 percent—more than twice as much
  • The rise in suicide, too, is more pronounced among girls. Although the rate increased for both sexes, three times as many 12-to-14-year-old girls killed themselves in 2015 as in 2007, compared with twice as many boys
  • Social media give middle- and high-school girls a platform on which to carry out the style of aggression they favor, ostracizing and excluding other girls around the clock.
  • I asked my undergraduate students at San Diego State University what they do with their phone while they sleep. Their answers were a profile in obsession. Nearly all slept with their phone, putting it under their pillow, on the mattress, or at the very least within arm’s reach of the bed. They checked social media right before they went to sleep, and reached for their phone as soon as they woke up in the morning
  • the smartphone is cutting into teens’ sleep: Many now sleep less than seven hours most nights. Sleep experts say that teens should get about nine hours of sleep a night; a teen who is getting less than seven hours a night is significantly sleep deprived
  • Fifty-seven percent more teens were sleep deprived in 2015 than in 1991. In just the four years from 2012 to 2015, 22 percent more teens failed to get seven hours of sleep.
  • Two national surveys show that teens who spend three or more hours a day on electronic devices are 28 percent more likely to get less than seven hours of sleep than those who spend fewer than three hours, and teens who visit social-media sites every day are 19 percent more likely to be sleep deprived.
  • Teens who read books and magazines more often than the average are actually slightly less likely to be sleep deprived—either reading lulls them to sleep, or they can put the book down at bedtime.
  • Sleep deprivation is linked to myriad issues, including compromised thinking and reasoning, susceptibility to illness, weight gain, and high blood pressure. It also affects mood: People who don’t sleep enough are prone to depression and anxiety.
  • correlations between depression and smartphone use are strong enough to suggest that more parents should be telling their kids to put down their phone.
  • What’s at stake isn’t just how kids experience adolescence. The constant presence of smartphones is likely to affect them well into adulthood. Among people who suffer an episode of depression, at least half become depressed again later in life. Adolescence is a key time for developing social skills; as teens spend less time with their friends face-to-face, they have fewer opportunities to practice them
  • Significant effects on both mental health and sleep time appear after two or more hours a day on electronic devices. The average teen spends about two and a half hours a day on electronic devices. Some mild boundary-setting could keep kids from falling into harmful habits.

The Coming Software Apocalypse - The Atlantic - 1 views

  • Our standard framework for thinking about engineering failures—reflected, for instance, in regulations for medical devices—was developed shortly after World War II, before the advent of software, for electromechanical systems. The idea was that you make something reliable by making its parts reliable (say, you build your engine to withstand 40,000 takeoff-and-landing cycles) and by planning for the breakdown of those parts (you have two engines). But software doesn’t break. Intrado’s faulty threshold is not like the faulty rivet that leads to the crash of an airliner. The software did exactly what it was told to do. In fact it did it perfectly. The reason it failed is that it was told to do the wrong thing.
  • Software failures are failures of understanding, and of imagination. Intrado actually had a backup router, which, had it been switched to automatically, would have restored 911 service almost immediately. But, as described in a report to the FCC, “the situation occurred at a point in the application logic that was not designed to perform any automated corrective actions.”
  • The introduction of programming languages like Fortran and C, which resemble English, and tools, known as “integrated development environments,” or IDEs, that help correct simple mistakes (like Microsoft Word’s grammar checker but for code), obscured, though did little to actually change, this basic alienation—the fact that the programmer didn’t work on a problem directly, but rather spent their days writing out instructions for a machine.
  • ...52 more annotations...
  • Code is too hard to think about. Before trying to understand the attempts themselves, then, it’s worth understanding why this might be: what it is about code that makes it so foreign to the mind, and so unlike anything that came before it.
  • Technological progress used to change the way the world looked—you could watch the roads getting paved; you could see the skylines rise. Today you can hardly tell when something is remade, because so often it is remade by code.
  • Software has enabled us to make the most intricate machines that have ever existed. And yet we have hardly noticed, because all of that complexity is packed into tiny silicon chips as millions and millions of lines of cod
  • The programmer, the renowned Dutch computer scientist Edsger Dijkstra wrote in 1988, “has to be able to think in terms of conceptual hierarchies that are much deeper than a single mind ever needed to face before.” Dijkstra meant this as a warning.
  • As programmers eagerly poured software into critical systems, they became, more and more, the linchpins of the built world—and Dijkstra thought they had perhaps overestimated themselves.
  • What made programming so difficult was that it required you to think like a computer.
  • “The problem is that software engineers don’t understand the problem they’re trying to solve, and don’t care to,” says Leveson, the MIT software-safety expert. The reason is that they’re too wrapped up in getting their code to work.
  • Though he runs a lab that studies the future of computing, he seems less interested in technology per se than in the minds of the people who use it. Like any good toolmaker, he has a way of looking at the world that is equal parts technical and humane. He graduated top of his class at the California Institute of Technology for electrical engineering,
  • “The serious problems that have happened with software have to do with requirements, not coding errors.” When you’re writing code that controls a car’s throttle, for instance, what’s important is the rules about when and how and by how much to open it. But these systems have become so complicated that hardly anyone can keep them straight in their head. “There’s 100 million lines of code in cars now,” Leveson says. “You just cannot anticipate all these things.”
  • a nearly decade-long investigation into claims of so-called unintended acceleration in Toyota cars. Toyota blamed the incidents on poorly designed floor mats, “sticky” pedals, and driver error, but outsiders suspected that faulty software might be responsible
  • software experts spend 18 months with the Toyota code, picking up where NASA left off. Barr described what they found as “spaghetti code,” programmer lingo for software that has become a tangled mess. Code turns to spaghetti when it accretes over many years, with feature after feature piling on top of, and being woven around
  • Using the same model as the Camry involved in the accident, Barr’s team demonstrated that there were actually more than 10 million ways for the onboard computer to cause unintended acceleration. They showed that as little as a single bit flip—a one in the computer’s memory becoming a zero or vice versa—could make a car run out of control. The fail-safe code that Toyota had put in place wasn’t enough to stop it
  • . In all, Toyota recalled more than 9 million cars, and paid nearly $3 billion in settlements and fines related to unintended acceleration.
  • The problem is that programmers are having a hard time keeping up with their own creations. Since the 1980s, the way programmers work and the tools they use have changed remarkably little.
  • “Visual Studio is one of the single largest pieces of software in the world,” he said. “It’s over 55 million lines of code. And one of the things that I found out in this study is more than 98 percent of it is completely irrelevant. All this work had been put into this thing, but it missed the fundamental problems that people faced. And the biggest one that I took away from it was that basically people are playing computer inside their head.” Programmers were like chess players trying to play with a blindfold on—so much of their mental energy is spent just trying to picture where the pieces are that there’s hardly any left over to think about the game itself.
  • The fact that the two of them were thinking about the same problem in the same terms, at the same time, was not a coincidence. They had both just seen the same remarkable talk, given to a group of software-engineering students in a Montreal hotel by a computer researcher named Bret Victor. The talk, which went viral when it was posted online in February 2012, seemed to be making two bold claims. The first was that the way we make software is fundamentally broken. The second was that Victor knew how to fix it.
  • This is the trouble with making things out of code, as opposed to something physical. “The complexity,” as Leveson puts it, “is invisible to the eye.”
  • in early 2012, Victor had finally landed upon the principle that seemed to thread through all of his work. (He actually called the talk “Inventing on Principle.”) The principle was this: “Creators need an immediate connection to what they’re creating.” The problem with programming was that it violated the principle. That’s why software systems were so hard to think about, and so rife with bugs: The programmer, staring at a page of text, was abstracted from whatever it was they were actually making.
  • “Our current conception of what a computer program is,” he said, is “derived straight from Fortran and ALGOL in the late ’50s. Those languages were designed for punch cards.”
  • WYSIWYG (pronounced “wizzywig”) came along. It stood for “What You See Is What You Get.”
  • Victor’s point was that programming itself should be like that. For him, the idea that people were doing important work, like designing adaptive cruise-control systems or trying to understand cancer, by staring at a text editor, was appalling.
  • With the right interface, it was almost as if you weren’t working with code at all; you were manipulating the game’s behavior directly.
  • When the audience first saw this in action, they literally gasped. They knew they weren’t looking at a kid’s game, but rather the future of their industry. Most software involved behavior that unfolded, in complex ways, over time, and Victor had shown that if you were imaginative enough, you could develop ways to see that behavior and change it, as if playing with it in your hands. One programmer who saw the talk wrote later: “Suddenly all of my tools feel obsolete.”
  • hen John Resig saw the “Inventing on Principle” talk, he scrapped his plans for the Khan Academy programming curriculum. He wanted the site’s programming exercises to work just like Victor’s demos. On the left-hand side you’d have the code, and on the right, the running program: a picture or game or simulation. If you changed the code, it’d instantly change the picture. “In an environment that is truly responsive,” Resig wrote about the approach, “you can completely change the model of how a student learns ... [They] can now immediately see the result and intuit how underlying systems inherently work without ever following an explicit explanation.” Khan Academy has become perhaps the largest computer-programming class in the world, with a million students, on average, actively using the program each month.
  • The ideas spread. The notion of liveness, of being able to see data flowing through your program instantly, made its way into flagship programming tools offered by Google and Apple. The default language for making new iPhone and Mac apps, called Swift, was developed by Apple from the ground up to support an environment, called Playgrounds, that was directly inspired by Light Table.
  • “Typically the main problem with software coding—and I’m a coder myself,” Bantegnie says, “is not the skills of the coders. The people know how to code. The problem is what to code. Because most of the requirements are kind of natural language, ambiguous, and a requirement is never extremely precise, it’s often understood differently by the guy who’s supposed to code.”
  • In a pair of later talks, “Stop Drawing Dead Fish” and “Drawing Dynamic Visualizations,” Victor went one further. He demoed two programs he’d built—the first for animators, the second for scientists trying to visualize their data—each of which took a process that used to involve writing lots of custom code and reduced it to playing around in a WYSIWYG interface.
  • Victor suggested that the same trick could be pulled for nearly every problem where code was being written today. “I’m not sure that programming has to exist at all,” he told me. “Or at least software developers.” In his mind, a software developer’s proper role was to create tools that removed the need for software developers. Only then would people with the most urgent computational problems be able to grasp those problems directly, without the intermediate muck of code.
  • Victor implored professional software developers to stop pouring their talent into tools for building apps like Snapchat and Uber. “The inconveniences of daily life are not the significant problems,” he wrote. Instead, they should focus on scientists and engineers—as he put it to me, “these people that are doing work that actually matters, and critically matters, and using really, really bad tools.”
  • Bantegnie’s company is one of the pioneers in the industrial use of model-based design, in which you no longer write code directly. Instead, you create a kind of flowchart that describes the rules your program should follow (the “model”), and the computer generates code for you based on those rules
  • In a model-based design tool, you’d represent this rule with a small diagram, as though drawing the logic out on a whiteboard, made of boxes that represent different states—like “door open,” “moving,” and “door closed”—and lines that define how you can get from one state to the other. The diagrams make the system’s rules obvious: Just by looking, you can see that the only way to get the elevator moving is to close the door, or that the only way to get the door open is to stop.
  • . In traditional programming, your task is to take complex rules and translate them into code; most of your energy is spent doing the translating, rather than thinking about the rules themselves. In the model-based approach, all you have is the rules. So that’s what you spend your time thinking about. It’s a way of focusing less on the machine and more on the problem you’re trying to get it to solve.
  • “Everyone thought I was interested in programming environments,” he said. Really he was interested in how people see and understand systems—as he puts it, in the “visual representation of dynamic behavior.” Although code had increasingly become the tool of choice for creating dynamic behavior, it remained one of the worst tools for understanding it. The point of “Inventing on Principle” was to show that you could mitigate that problem by making the connection between a system’s behavior and its code immediate.
  • On this view, software becomes unruly because the media for describing what software should do—conversations, prose descriptions, drawings on a sheet of paper—are too different from the media describing what software does do, namely, code itself.
  • for this approach to succeed, much of the work has to be done well before the project even begins. Someone first has to build a tool for developing models that are natural for people—that feel just like the notes and drawings they’d make on their own—while still being unambiguous enough for a computer to understand. They have to make a program that turns these models into real code. And finally they have to prove that the generated code will always do what it’s supposed to.
  • tice brings order and accountability to large codebases. But, Shivappa says, “it’s a very labor-intensive process.” He estimates that before they used model-based design, on a two-year-long project only two to three months was spent writing code—the rest was spent working on the documentation.
  • uch of the benefit of the model-based approach comes from being able to add requirements on the fly while still ensuring that existing ones are met; with every change, the computer can verify that your program still works. You’re free to tweak your blueprint without fear of introducing new bugs. Your code is, in FAA parlance, “correct by construction.”
  • “people are not so easily transitioning to model-based software development: They perceive it as another opportunity to lose control, even more than they have already.”
  • The bias against model-based design, sometimes known as model-driven engineering, or MDE, is in fact so ingrained that according to a recent paper, “Some even argue that there is a stronger need to investigate people’s perception of MDE than to research new MDE technologies.”
  • “Human intuition is poor at estimating the true probability of supposedly ‘extremely rare’ combinations of events in systems operating at a scale of millions of requests per second,” he wrote in a paper. “That human fallibility means that some of the more subtle, dangerous bugs turn out to be errors in design; the code faithfully implements the intended design, but the design fails to correctly handle a particular ‘rare’ scenario.”
  • Newcombe was convinced that the algorithms behind truly critical systems—systems storing a significant portion of the web’s data, for instance—ought to be not just good, but perfect. A single subtle bug could be catastrophic. But he knew how hard bugs were to find, especially as an algorithm grew more complex. You could do all the testing you wanted and you’d never find them all.
  • An algorithm written in TLA+ could in principle be proven correct. In practice, it allowed you to create a realistic model of your problem and test it not just thoroughly, but exhaustively. This was exactly what he’d been looking for: a language for writing perfect algorithms.
  • TLA+, which stands for “Temporal Logic of Actions,” is similar in spirit to model-based design: It’s a language for writing down the requirements—TLA+ calls them “specifications”—of computer programs. These specifications can then be completely verified by a computer. That is, before you write any code, you write a concise outline of your program’s logic, along with the constraints you need it to satisfy
  • Programmers are drawn to the nitty-gritty of coding because code is what makes programs go; spending time on anything else can seem like a distraction. And there is a patient joy, a meditative kind of satisfaction, to be had from puzzling out the micro-mechanics of code. But code, Lamport argues, was never meant to be a medium for thought. “It really does constrain your ability to think when you’re thinking in terms of a programming language,”
  • Code makes you miss the forest for the trees: It draws your attention to the working of individual pieces, rather than to the bigger picture of how your program fits together, or what it’s supposed to do—and whether it actually does what you think. This is why Lamport created TLA+. As with model-based design, TLA+ draws your focus to the high-level structure of a system, its essential logic, rather than to the code that implements it.
  • But TLA+ occupies just a small, far corner of the mainstream, if it can be said to take up any space there at all. Even to a seasoned engineer like Newcombe, the language read at first as bizarre and esoteric—a zoo of symbols.
  • this is a failure of education. Though programming was born in mathematics, it has since largely been divorced from it. Most programmers aren’t very fluent in the kind of math—logic and set theory, mostly—that you need to work with TLA+. “Very few programmers—and including very few teachers of programming—understand the very basic concepts and how they’re applied in practice. And they seem to think that all they need is code,” Lamport says. “The idea that there’s some higher level than the code in which you need to be able to think precisely, and that mathematics actually allows you to think precisely about it, is just completely foreign. Because they never learned it.”
  • “In the 15th century,” he said, “people used to build cathedrals without knowing calculus, and nowadays I don’t think you’d allow anyone to build a cathedral without knowing calculus. And I would hope that after some suitably long period of time, people won’t be allowed to write programs if they don’t understand these simple things.”
  • Programmers, as a species, are relentlessly pragmatic. Tools like TLA+ reek of the ivory tower. When programmers encounter “formal methods” (so called because they involve mathematical, “formally” precise descriptions of programs), their deep-seated instinct is to recoil.
  • Formal methods had an image problem. And the way to fix it wasn’t to implore programmers to change—it was to change yourself. Newcombe realized that to bring tools like TLA+ to the programming mainstream, you had to start speaking their language.
  • he presented TLA+ as a new kind of “pseudocode,” a stepping-stone to real code that allowed you to exhaustively test your algorithms—and that got you thinking precisely early on in the design process. “Engineers think in terms of debugging rather than ‘verification,’” he wrote, so he titled his internal talk on the subject to fellow Amazon engineers “Debugging Designs.” Rather than bemoan the fact that programmers see the world in code, Newcombe embraced it. He knew he’d lose them otherwise. “I’ve had a bunch of people say, ‘Now I get it,’” Newcombe says.
  • In the world of the self-driving car, software can’t be an afterthought. It can’t be built like today’s airline-reservation systems or 911 systems or stock-trading systems. Code will be put in charge of hundreds of millions of lives on the road and it has to work. That is no small task.

How humans became the best throwers on the planet - 0 views

  • From 2008 to 2020, the average speeds of all major league baseball pitches combined rose by between 1.5 mph and 2 mph.
  • But MLB pitchers aren’t the only expert throwers; most healthy people can throw faster than our much stronger chimpanzee relatives, who max out at around 30 mph. A study of boys from the ages of 8 to 14 who were only moderately trained in throwing could still throw two times faster than chimps.
  • Humans are the only species that can throw well enough to kill rivals and prey. Because throwing requires the highly coordinated and extraordinarily rapid movements of multiple body parts, there was likely a long history of selection favoring the evolution of expert throwing in our ancestors.
  • ...3 more annotations...
  • The Australopithecines, the relatively small-brained, bipedal ancestors of our genus that lived in Africa somewhere between 1 million and 4 million years ago, probably threw projectiles as well, since their hand bones hint at their ability to grip objects and throw them.
  • Once the ability to throw quickly and accurately became critical to success in combat and hunting, our male ancestors would have been more likely than females to develop, through natural selection, these skills, since anthropologists have shown that males tended to fight and hunt big game.
  • Sex differences in throwing do not exist just because males are, on average, larger and stronger. The relative size, shape and orientation of the shoulders of men increase the range of motion of the arm during the cocking phase, which facilitates better throwing.

Wealthy, Male and American Students More Likely to BS | Time - 0 views

  • Students who are wealthier and male are more likely than others to claim that they know more than they actually do, says a new study.
  • The study, which reviewed surveys of 40,000 15-year-old students from across nine English-speaking countries, found that boys and people from wealthier families are more likely to be “bullshitters,” which it defines as “individuals who claim knowledge or expertise in an area where they actually have little experience at all.”
  • “You’re claiming expertise in things you have absolutely no knowledge of,” says Shure. “You couldn’t. These things don’t exist.”

  • The countries where students were guilty of the most BS? The U.S. and Canada. Students in the two counties had scores that were .25 and .3 above average on the study’s “bullshit scale.” However, the two counties also had the narrowest gap between boys and girls, with a gap of .25 and .34 between the genders. In England and Ireland, the gap was much wider – .48 and .46 points.
  • Shure says that she is interested in determining whether a person’s ability to BS has a major impact on economic inequality between men and women, and how the ability plays out across socioeconomic lines.
  • “You can imagine that the people that score high on this bullshit index are good at certain things that might be rewarded,” says Shure. “It might be an interview to get into college. It could be an interview for a job, or an internship. It could be those skills end up helping exacerbate the gap that we observe between people from rich backgrounds and poor backgrounds, and even men and women.”
  • However, Shure says that it’s conceivable that “bullshitters” may have an advantage when it comes to getting ahead: “They clearly have very high opinions of themselves. And that could be associated with becoming leaders in the future.”

Why it's Important to Understand Economics | Federal Reserve Bank of Minneapolis - 1 views

  • The case for economic literacy is a strong one.
  • Economic literacy certainly contributes to the first class of knowledge. People like to think and talk about the economic issues that affect them as consumers, workers, producers, investors, citizens and in other roles they assume over a lifetime.
  • Economic literacy also gives people the tools for understanding their economic world and how to interpret events that will either directly or indirectly affect them.
  • ...15 more annotations...
  • Economic literacy contributes to a second class of knowledge.
  • For some economic decisions, such as buying a home or investing in the stock market, it is possible to hire professional or technical help when making a choice, but in most cases it is neither economical nor practical for an individual to hire a skilled professional every time an economic decision needs to be made.
  • There are three essential ingredients for effective economic education in the schools.
  • The development of economic literacy must begin in the schools. Even young children are capable of learning basic economic concepts that help them understand their economic world. In the secondary years, that initial foundation can be expanded to include instruction in a broader set of economic ideas and concepts
  • Some may think that economics is too difficult a subject to be taught to children and youth, and that such instruction should wait until college
  • Waiting until students are in college to teach economics is simply a matter of "too little and too late." The majority of students end their formal education with secondary school, and even those students who continue their learning at a college or university may not take an economics course.
  • Economic literacy improves the competence of each individual for making personal and social decisions about the multitude of economic issues that will be encountered over a lifetime.
  • First, teachers must be knowledgeable about the subject and be able to help students learn how to use basic economic concepts to analyze personal and social issues. Second, good curriculum guides and instructional materials are needed that present economic content at an appropriate level for the student to understand. Third, economics must have a central place in the school curriculum—similar to math, science, history and language arts—so that substantial classroom time is devoted to economics instruction
  • Over the past 40 years there has been a significant improvement in each area.
  • A study of high school transcripts shows that only about 44 percent of high school students take a separate course in economics. This course is usually offered in the 12th grade as an elective and lasts for only a semester.
  • Given this situation—that fewer than half of high school graduates take a course in economics—it should not be surprising that study after study show that there is widespread economic illiteracy among youth and the American public.
  • Some 87 percent of high school seniors rated their knowledge and understanding of economic and economic issues as only fair or poor.
  • Knowing what determines prices in a market economy and accepting the outcomes are two different things. If demand or supply conditions change, prices in a competitive market will rise and fall. Having a basic understanding of how markets work does not always mean that people will like price changes, especially if prices rise, but it should increase the probability of accepting the market outcome
  • The development of basic economic literacy is an important goal for a democratic society that relies heavily on informed citizenry and personal economic decision-making.
  • To achieve that goal will require that significant gaps in the economic education of youth be closed by giving economics a more central place in the school curriculum. More economics coursework at the precollege level sets a foundation for economic literacy, but it is only the beginning.

Free Market - Econlib - 0 views

  • Free market” is a summary term for an array of exchanges that take place in society.
  • Each exchange is undertaken as a voluntary agreement between two people or between groups of people represented by agents. These two individuals (or agents) exchange two economic goods, either tangible commodities or nontangible services
  • Both parties undertake the exchange because each expects to gain from it. Also, each will repeat the exchange next time (or refuse to) because his expectation has proved correct (or incorrect) in the recent past.
  • ...25 more annotations...
  • Trade, or exchange, is engaged in precisely because both parties benefit; if they did not expect to gain, they would not agree to the exchange.
  • This simple reasoning refutes the argument against free trade typical of the “mercantilist” period of sixteenth- to eighteenth-century Europe and classically expounded by the famed sixteenth-century French essayist Montaigne.
  • The mercantilists argued that in any trade, one party can benefit only at the expense of the other—that in every transaction there is a winner and a loser, an “exploiter” and an “exploited.”
  • We can immediately see the fallacy in this still-popular viewpoint: the willingness and even eagerness to trade means that both parties benefit. In modern game-theory jargon, trade is a win-win situation, a “positive-sum” rather than a “zero-sum” or “negative-sum” game.
  • Each one values the two goods or services differently, and these differences set the scene for an exchange.
  • Two factors determine the terms of any agreement: how much each participant values each good in question, and each participant’s bargaining skills.
  • the market in relation to how favorably buyers evaluate these goods—in shorthand, by the interaction of their supply with the demand for them.
  • On the other hand, given the buyers’ evaluation, or demand, for a good, if the supply increases, each unit of supply—each baseball card or loaf of bread—will fall in value, and therefore the price of the good will fall. The reverse occurs if the supply of the good decreases.
  • The market, then, is not simply an array; it is a highly complex, interacting latticework of exchanges.
  • Production begins with natural resources, and then various forms of machines and capital goods, until finally, goods are sold to the consumer.
  • At each stage of production from natural resource to consumer good, money is voluntarily exchanged for capital goods, labor services, and land resources. At each step of the way, terms of exchanges, or prices, are determined by the voluntary interactions of suppliers and demanders. This market is “free” because choices, at each step, are made freely and voluntarily.
  • The free market and the free price system make goods from around the world available to consumers.
  • Saving and investment can then develop capital goods and increase the productivity and wages of workers, thereby increasing their standard of living.
  • The free competitive market also rewards and stimulates technological innovation that allows the innovator to get a head start in satisfying consumer wants in new and creative ways.
  • Government, in every society, is the only lawful system of coercion. Taxation is a coerced exchange, and the heavier the burden of taxation on production, the more likely it is that economic growth will falter and decline
  • The ultimate in government coercion is socialism.
  • Under socialist central planning the socialist planning board lacks a price system for land or capital goods.
  • Market socialism is, in fact, a contradiction in terms.
  • The fashionable discussion of market socialism often overlooks one crucial aspect of the market: When two goods are exchanged, what is really exchanged is the property titles in those goods.
  • This means that the key to the existence and flourishing of the free market is a society in which the rights and titles of private property are respected, defended, and kept secure.
  • The key to socialism, on the other hand, is government ownership of the means of production, land, and capital goods.
  • Under socialism, therefore, there can be no market in land or capital goods worthy of the name.
  • ome critics of the free market argue that property rights are in conflict with “human” rights. But the critics fail to realize that in a free-market system, every person has a property right over his own person and his own labor and can make free contracts for those services.
  • A common charge against the free-market society is that it institutes “the law of the jungle,” of “dog eat dog,” that it spurns human cooperation for competition and exalts material success as opposed to spiritual values, philosophy, or leisure activities.
  • It is the coercive countries with little or no market activity—the notable examples in the last half of the twentieth century were the communist countries—where the grind of daily existence not only impoverishes people materially but also deadens their spirit.

Opinion | Trump May Start a Social Network. Here's My Advice. - The New York Times - 0 views

  • Trump May Start a Social Network. Here’s My Advice.
  • Recast your past failures as successes, engage in meaningless optics, and other tips from the Silicon Valley playbook.
  • So Donald Trump wants to start a social network and become a tech mogul?
  • ...26 more annotations...
  • I am an expert in all things digital, and I’m willing to help.
  • Tech is hard stuff, and new ventures should be attempted with extreme care, especially by those whose history of entrepreneurship is littered with the carcasses of, say, Trump Steaks.
  • Or Trump Water. Or Trump University. Or Trump magazine. Or Trump Casinos. Or Trump Mortgages. Or Trump Airlines. Or Trump Vodka. Or the Trump pandemic response. Or, of course, the 2020 Trump presidential campaign.
  • So, Mr. Trump, here’s my advice.
  • I advise you to embrace your myriad failures as if they’re your best friends.
  • Even if “fail” and “don’t work” are the same thing, in tech these are seen as a badge of honor rather than as a sign that you are terrible at executing a business plan and engage in only meaningless optics.
  • Engage in meaningless optics.
  • uckily, this fits right in your wheelhouse — a talent that you have displayed in spades since the beginnings of your career.
  • “genius is 1 percent inspiration and 99 percent perspiration.” I might rephrase that for your entry into tech by saying, genius is 1 percent instigation and 99 percent perfidy.
  • Instigation and perfidy, in fact, make the perfect formula for a modern-day social network, so you are already well on your way, given your skill set.
  • Baseless conspiracies? Check
  • Crazy ALL-CAP declarations designed to foment anger? Check.
  • Incessant lies? Check.
  • Self-aggrandizing though badly spelled streams that actually reveal a profound lack of self-esteem? Check.
  • Link-baiting hateful memes? Double check.
  • Inciting violence over election fraud with both explicit and cryptic messages to your base, in order to get them to think they should attack the Capitol, like, for real? Checkmate
  • hate-tweet at you, and, of course, all the fake media
  • You didn’t start the fire — well, maybe you did — but you definitely need to keep stoking it.
  • A social network requires a lot of it, including servers, apps and content moderation tools. You’ll need a whole army of geeks whom you’ll have to pay real money.
  • As for your future competitors … Twitter has seen its shares rise sharply since it tossed you off for life.
  • You still might get a reprieve over at Facebook, where an oversight board is contemplating your fate. We’ll see what the chief executive, Mark Zuckerberg, decides after the board makes a ruling.
  • Keep in mind, Mr. Zuckerberg really is the most powerful man in the world; that was even the case when you were in the Oval Office.
  • And while he once bear-hugged your administration, he is now sidling up to President Biden.
  • Avoid MeinSpace and InstaGraft, for obvious reasons. The narcissist in you might go for The_Donald, which you might now be able to use, since Reddit banned the 800,000-member forum with that name for violating its rules against harassment, hate speech, content manipulation and more.
  • (Sounds like just the kind of folks you like and who like you.)
  • Trumpets are brash and loud, and they’re often badly played and tinny. Right on brand, I’d say.

Revisiting the prophetic work of Neil Postman about the media » MercatorNet - 1 views

  • The NYU professor was surely prophetic. “Our own tribe is undergoing a vast and trembling shift from the magic of writing to the magic of electronics,” he cautioned.
  • “We face the rapid dissolution of the assumptions of an education organised around the slow-moving printed word, and the equally rapid emergence of a new education based on the speed-of-light electronic message.”
  • What Postman perceived in television has been dramatically intensified by smartphones and social media
  • ...31 more annotations...
  • Postman also recognised that technology was changing our mental processes and social habits.
  • Today corporations like Google and Amazon collect data on Internet users based on their browsing history, the things they purchase, and the apps they use
  • Yet all citizens are undergoing this same transformation. Our digital devices undermine social interactions by isolating us,
  • “Years from now, it will be noticed that the massive collection and speed-of-light retrieval of data have been of great value to large-scale organisations, but have solved very little of importance to most people, and have created at least as many problems for them as they may have solved.”
  • “Television has by its power to control the time, attention, and cognitive habits of our youth gained the power to control their education.”
  • As a student of Canadian philosopher Marshall McLuhan, Postman believed that the medium of information was critical to understanding its social and political effects. Every technology has its own agenda. Postman worried that the very nature of television undermined American democratic institutions.
  • Many Americans tuned in to the presidential debate looking for something substantial and meaty
  • It was simply another manifestation of the incoherence and vitriol of cable news
  • “When, in short, a people become an audience and their public business a vaudeville act, then a nation finds itself at risk; culture-death is a clear possibility,” warned Postman.
  • Technology Is Never Neutral
  • As for new problems, we have increased addictions (technological and pornographic); increased loneliness, anxiety, and distraction; and inhibited social and intellectual maturation.
  • The average length of a shot on network television is only 3.5 seconds, so that the eye never rests, always has something new to see. Moreover, television offers viewers a variety of subject matter, requires minimal skills to comprehend it, and is largely aimed at emotional gratification.
  • This is far truer of the Internet and social media, where more than a third of Americans, and almost half of young people, now get their news.
  • with smartphones now ubiquitous, the Internet has replaced television as the “background radiation of the social and intellectual universe.”
  • Is There Any Solution?
  • Reading news or commentary in print, in contrast, requires concentration, patience, and careful reflection, virtues that our digital age vitiates.
  • Politics as Entertainment
  • “How television stages the world becomes the model for how the world is properly to be staged,” observed Postman. In the case of politics, television fashions public discourse into yet another form of entertainment
  • In America, the fundamental metaphor for political discourse is the television commercial. The television commercial is not at all about the character of products to be consumed. … They tell everything about the fears, fancies, and dreams of those who might buy them.
  • The television commercial has oriented business away from making products of value and towards making consumers feel valuable, which means that the business of business has now become pseudo-therapy. The consumer is a patient assured by psycho-dramas.
  • Such is the case with the way politics is “advertised” to different subsets of the American electorate. The “consumer,” depending on his political leanings, may be manipulated by fears of either an impending white-nationalist, fascist dictatorship, or a radical, woke socialist takeover.
  • This paradigm is aggravated by the hypersiloing of media content, which explains why Americans who read left-leaning media view the Proud Boys as a legitimate, existential threat to national civil order, while those who read right-leaning media believe the real immediate enemies of our nation are Antifa
  • Regardless of whether either of these groups represents a real public menace, the loss of any national consensus over what constitutes objective news means that Americans effectively talk past one another: they use the Proud Boys or Antifa as rhetorical barbs to smear their ideological opponents as extremists.
  • Yet these technologies are far from neutral. They are, rather, “equipped with a program for social change.
  • Postman’s analysis of technology is prophetic and profound. He warned of the trivialising of our media, defined by “broken time and broken attention,” in which “facts push other facts into and then out of consciousness at speeds that neither permit nor require evaluation.” He warned of “a neighborhood of strangers and pointless quantity.”
  • does Postman offer any solutions to this seemingly uncontrollable technological juggernaut?
  • Postman’s suggestions regarding education are certainly relevant. He unequivocally condemned education that mimics entertainment, and urged a return to learning that is hierarchical, meaning that it first gives students a foundation of essential knowledge before teaching “critical thinking.”
  • Postman also argued that education must avoid a lowest-common-denominator approach in favor of complexity and the perplexing: the latter method elicits in the student a desire to make sense of what perplexes him.
  • Finally, Postman promoted education of vigorous exposition, logic, and rhetoric, all being necessary for citizenship
  • Another course of action is to understand what these media, by their very nature, do to us and to public discourse.
  • We must, as Postman exhorts us, “demystify the data” and dominate our technology, lest it dominate us. We must identify and resist how television, social media, and smartphones manipulate our emotions, infantilise us, and weaken our ability to rebuild what 2020 has ravaged.

The Importance of Logic and Critical Thinking | WIRED - 0 views

  • The rationality of the world is what is at risk. Too many people are taken advantage of because of their lack of critical thinking, logic and deductive reasoning
  • These same people are raising children without these same skills, creating a whole new generation of clueless people.
  • However, valid logic does not always guarantee truth or a sound argument.
  • ...3 more annotations...
  • Valid logic is when the structure of logic is correct in the way of syntax and semantics rather than truth.
  • The basic lesson here is that, while the logic above might seem valid because of the structure of the statement, it takes a further understanding to figure out why it's not necessarily true
  • The underlying lesson here is not to immediately assume everything you read or are told is true, something all children need to and should learn.
