Opinion | What Are Republicans So Afraid Of? - The New York Times - 0 views

  • What Are Republicans So Afraid Of?
  • Instead of conspiracy-mongering about an election they did well in, they could try to win real majorities.
  • There was a time, in recent memory, when the Republican Party both believed it could win a national majority and actively worked to build one.
  • ...13 more annotations...
  • Whether shrewd or misguided, cynical or sincere — or outright cruel and divisive — these gambits were each part of an effort to expand the Republican coalition as far as it could go without abandoning Reaganite conservatism itself.
  • It was the work of a self-assured political movement, confident that it could secure a position as the nation’s de facto governing party.
  • There is no such ambition, or confidence, in today’s Republican Party.
  • Republicans have made it their mission to restrict the vote as much as possible.
  • Conservative grass-roots and political action groups are joining the crusade, according to reporting by my newsroom colleague Jeremy Peters, galvanized into action by the former president, who blames nonexistent fraud and illegal voting for his defeat.
  • “So here’s the good news: There is action taking place to go back and correct what was uncovered in this last election.”
  • “It kind of feels like an all-hands-on-deck moment for the conservative movement, when the movement writ large realizes the sanctity of our elections is paramount and voter distrust is at an all-time high,”
  • H.R. 1’s only objective is to ensure that Democrats can never again lose another election, that they will win and maintain control of the House of Representatives and the Senate and of the state legislatures for the next century,”
  • Some of this is undoubtedly cynical, a brazen attempt to capitalize on the conspiratorial rhetoric of the former president. But some of it is sincere, a genuine belief that the Republican Party will cease to exist if it cannot secure “election integrity.”
  • If Republicans could break themselves of Trump and look at last November with clear eyes, they would see that their fears of demographic eclipse are overblown and that they can compete — even thrive — in the kinds of high-turnout elections envisioned by voting rights activists.
  • Indeed, the great irony of the Republican Party’s drive to restrict the vote in the name of Trump is that it burdens the exact voters he brought to the polls.
  • Under Trump, the Republican Party swapped some of the most likely voters — white college-educated moderates — for some of the least likely — blue-collar men.
  • In other words, by killing measures that make voting more open to everyone, Republicans might make their fears of terminal decline a self-fulfilling prophecy.

America Is Flunking Math - Persuasion - 1 views

  • One can argue that the preeminence of each civilization was, in part, due to their sophisticated understanding and use of mathematics. This is particularly clear in the case of the West, which forged ahead in the 17th century with the discovery of calculus, one of the greatest scientific breakthroughs of all time.
  • The United States became the dominant force in the mathematical sciences in the wake of World War II, largely due to the disastrous genocidal policies of the Third Reich. The Nazis’ obsession with purging German science of what it viewed as nefarious Jewish influence led to a massive exodus of Jewish mathematicians and scientists to America
  • Indeed, academic institutions in the United States have thrived largely because of their ability to attract talented individuals from around the world.
  • ...28 more annotations...
  • The quality of mathematics research in the United States today is the envy of the scientific world. This is a direct result of the openness and inclusivity of the profession.
  • According to our own experiences at the universities where we teach, an overwhelming majority of American students with strong math backgrounds are either foreign-born or first-generation students who have additional support from their education-conscious families. At all levels, STEM disciplines are more and more dependent on a constant flow of foreign talent.
  • The Organization for Economic Cooperation and Development compares mathematical proficiency among 15-year-olds by country worldwide. According to its 2018 report, America ranked 37th while China, America’s main competitor for world leadership, came in first.
  • This is despite the fact that the United States is the fifth-highest spender per pupil among the 37 developed OECD nations
  • This massive failure of our K-12 education system trickles through the STEM pipeline.
  • At the undergraduate level, too few American students are prepared for higher-level mathematics courses. These students are then unprepared for rigorous graduate-level work
  • Can Americans maintain this unmatched excellence in the future? There are worrisome signs that suggest not.
  • There are many reasons for this failure, but the way that we educate and prepare teachers is particularly influential. The vast majority of K-12 math teachers are graduates of teacher-preparation programs that teach very little substantive mathematics
  • This has led to a constant stream of ill-advised and dumbed-down reforms. One of the latest fads is anti-racist mathematics. Promoted in several states, the bizarre doctrine threatens to further degrade the teaching of mathematics.
  • Another major concern is the twisted interpretation of diversity, equity, and inclusion (DEI).
  • Under the banner of DEI, universities are abandoning the use of standardized tests like the SAT and GRE in admissions, and cities are considering scrapping academic tracking and various gifted programs in schools, which they deem “inequitable.”
  • such programs are particularly effective, when properly implemented, at discovering and encouraging talented children from disadvantaged backgrounds.
  • This will only lead to a further widening of racial disparities in educational outcomes while lowering American children’s rankings in education internationally.
  • These measures will not only hinder the progress of the generations of our future STEM workforce but also contribute to structural inequalities, as they are uniquely detrimental to students whose parents cannot send them to private schools or effective enrichment programs.
  • These are just a few examples of an unprecedented fervor for revolutionary change in the name of Critical Race Theory (CRT), a doctrine that views the world as a fierce battleground for the narratives of various identity groups.
  • The new 2021 Mathematics Framework, currently under consideration by California’s Department of Education, does away “with all tracking, acceleration, gifted programs, or any instruction that involves clustering by individual differences, without expressing any awareness of the impact these drastic alterations would have in preparing STEM-ready candidates.”
  • Ill-conceived DEI policies, often informed by CRT, and the declining standards of K-12 math education feed each other in a vicious circle
  • Regarding minorities, in particular, public K-12 education all too often produces students unprepared to compete, thus leading to large disparities in admissions at universities, graduate programs, and faculty positions. This disparity is then condemned as a manifestation of structural racism, resulting in administrative measures to lower the evaluation criteria. Lowering standards at all levels leads eventually to even worse outcomes and larger disparities, and so on in a downward spiral.
  • A case in point is the recent report by the American Mathematical Society that accuses the entire mathematics community, with the thinnest of specific evidence, of systemic racial discrimination. A major justification put forward for such a grave accusation is the lack of sufficient representation of Black mathematicians in the professio
  • the report, while raising awareness of several ugly facts from the long-ago past, makes little effort to address the real reasons for this, mainly the catastrophic failure of the K-12 mathematical educational system.
  • The National Science Foundation, a federal institution meant to support fundamental research, is now diverting some of its limited funding to various DEI initiatives of questionable benefit.
  • Meanwhile, other countries, especially China, are doing precisely the opposite, following the model of our past dedication to objective measures of excellence. How long before we will see a reverse exodus, away from the United States?
  • The present crisis can still be reversed by focusing on a few concrete actions:
  • Improve schools in urban areas and inner-city neighborhoods by following the most promising education programs. These programs demonstrate that inner-city children benefit if they are challenged by high standards and a nurturing environment.
  • Follow the lead of other highly successful rigorous programs such as BASIS schools and Math for America, which focus on rigorous STEM curricula, combined with 21st-century teaching methods, and recruit talented teachers to help them build on their STEM knowledge and teaching methods.
  • Increase, rather than eliminate, tailored instruction, both for accelerated and remedial math courses.
  • Reject the soft bigotry of low expectations, that Black children cannot do well in competitive mathematics programs and need dumbed-down ethnocentric versions of mathematics.
  • Uphold the objective selection process based on merit at all levels of education and research.

Opinion | Bias Is a Big Problem. But So Is 'Noise.' - The New York Times - 1 views

  • The word “bias” commonly appears in conversations about mistaken judgments and unfortunate decisions. We use it when there is discrimination, for instance against women or in favor of Ivy League graduates
  • the meaning of the word is broader: A bias is any predictable error that inclines your judgment in a particular direction. For instance, we speak of bias when forecasts of sales are consistently optimistic or investment decisions overly cautious.
  • Society has devoted a lot of attention to the problem of bias — and rightly so
  • ...26 more annotations...
  • when it comes to mistaken judgments and unfortunate decisions, there is another type of error that attracts far less attention: noise.
  • To see the difference between bias and noise, consider your bathroom scale. If on average the readings it gives are too high (or too low), the scale is biased
  • It is hard to escape the conclusion that sentencing is in part a lottery, because the punishment can vary by many years depending on which judge is assigned to the case and on the judge’s state of mind on that day. The judicial system is unacceptably noisy.
  • While bias is the average of errors, noise is their variability.
  • Although it is often ignored, noise is a large source of malfunction in society.
  • The average difference between the sentences that two randomly chosen judges gave for the same crime was more than 3.5 years. Considering that the mean sentence was seven years, that was a disconcerting amount of noise.
  • If it shows different readings when you step on it several times in quick succession, the scale is noisy.
  • How much of a difference would you expect to find between the premium values that two competent underwriters assigned to the same risk?
  • Executives in the insurance company said they expected about a 10 percent difference.
  • But the typical difference we found between two underwriters was an astonishing 55 percent of their average premium — more than five times as large as the executives had expected.
  • Many other studies demonstrate noise in professional judgments. Radiologists disagree on their readings of images and cardiologists on their surgery decisions
  • Wherever there is judgment, there is noise — and more of it than you think.
  • Noise causes error, as does bias, but the two kinds of error are separate and independent.
  • A company’s hiring decisions could be unbiased overall if some of its recruiters favor men and others favor women. However, its hiring decisions would be noisy, and the company would make many bad choices
  • Where does noise come from?
  • There is much evidence that irrelevant circumstances can affect judgments.
  • for instance, a judge’s mood, fatigue and even the weather can all have modest but detectable effects on judicial decisions.
  • people can have different general tendencies. Judges often vary in the severity of the sentences they mete out: There are “hanging” judges and lenient ones.
  • People can have not only different general tendencies (say, whether they are harsh or lenient) but also different patterns of assessment (say, which types of cases they believe merit being harsh or lenient about).
  • Underwriters differ in their views of what is risky, and doctors in their views of which ailments require treatment.
  • Once you become aware of noise, you can look for ways to reduce it.
  • independent judgments from a number of people can be averaged (a frequent practice in forecasting)
  • Guidelines, such as those often used in medicine, can help professionals reach better and more uniform decisions
  • imposing structure and discipline in interviews and other forms of assessment tends to improve judgments of job candidates.
  • No noise-reduction techniques will be deployed, however, if we do not first recognize the existence of noise.
  • Organizations and institutions, public and private, will make better decisions if they take noise seriously.

Social Media Effects on Teens | Impact of Social Media on Self-Esteem - 0 views

  • In fact, experts worry that the social media and text messages that have become so integral to teenage life are promoting anxiety and lowering self-esteem.
  • A survey conducted by the Royal Society for Public Health asked 14-24 year olds in the UK how social media platforms impacted their health and wellbeing. The survey results found that Snapchat, Facebook, Twitter and Instagram all led to increased feelings of depression, anxiety, poor body image and loneliness.
  • For one thing, modern teens are learning to do most of their communication while looking at a screen, not another person.
  • ...7 more annotations...
  • Learning how to make friends is a major part of growing up, and friendship requires a certain amount of risk-taking. This is true for making a new friend, but it’s also true for maintaining friendships. When there are problems that need to be faced—big ones or small ones—it takes courage to be honest about your feelings and then hear what the other person has to say
  • But when friendship is conducted online and through texts, kids are doing this in a context stripped of many of the most personal—and sometimes intimidating—aspects of communication
  • The other big danger that comes from kids communicating more indirectly is that it has gotten easier to be cruel. “Kids text all sorts of things that you would never in a million years contemplate saying to anyone’s face,”
  • “Girls are socialized more to compare themselves to other people, girls in particular, to develop their identities, so it makes them more vulnerable to the downside of all this.” She warns that a lack of solid self-esteem is often to blame. “We forget that relational aggression comes from insecurity and feeling awful about yourself, and wanting to put other people down so you feel better.”
  • . Teenage girls sort through hundreds of photos, agonizing over which ones to post online. Boys compete for attention by trying to out-gross one other, pushing the envelope as much as they can in the already disinhibited atmosphere online.
  • Another big change that has come with new technology and especially smart phones is that we are never really alone. Kids update their status, share what they’re watching, listening to, and reading, and have apps that let their friends know their specific location on a map at all times.
  • Offline, the gold standard advice for helping kids build healthy self-esteem is to get them involved in something that they’re interested in

Opinion | The Social Sciences' 'Physics Envy' - The New York Times - 0 views

  • Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,” “experiment,” “law”) evocative of physics and chemistry.
  • Many social scientists contend that science has a method, and if you want to be scientific, you should adopt it. The method requires you to devise a theoretical model, deduce a testable hypothesis from the model and then test the hypothesis against the world. If the hypothesis is confirmed, the theoretical model holds; if the hypothesis is not confirmed, the theoretical model does not hold. If your discipline does not operate by this method — known as hypothetico-deductivism — then in the minds of many, it’s not scientific.
  • it’s not even a good description of how the “hard” sciences work. It’s a high school textbook version of science, with everything messy and chaotic about scientific inquiry safely ignored.
  • ...9 more annotations...
  • For the sake of everyone who stands to gain from a better knowledge of politics, economics and society, the social sciences need to overcome their inferiority complex, reject hypothetico-deductivism and embrace the fact that they are mature disciplines with no need to emulate other sciences.
  • Or consider the famous “impossibility theorem,” developed by the economist Kenneth Arrow, which shows that no single voting system can simultaneously satisfy several important principles of fairness. There is no need to test this model with data — in fact, there is no way to test it — and yet the result offers policy makers a powerful lesson: there are unavoidable trade-offs in the design of voting systems.
  • Unfortunately, the belief that every theory must have its empirical support (and vice versa) now constrains the kinds of social science projects that are undertaken, alters the trajectory of academic careers and drives graduate training. Rather than attempt to imitate the hard sciences, social scientists would be better off doing what they do best: thinking deeply about what prompts human beings to behave the way they do.
  • theoretical models can be of great value even if they are never supported by empirical testing. In the 1950s, for instance, the economist Anthony Downs offered an elegant explanation for why rival political parties might adopt identical platforms during an election campaign. His model relied on the same strategic logic that explains why two competing gas stations or fast-food restaurants locate across the street from each other — if you don’t move to a central location but your opponent does, your opponent will nab those voters (customers). The best move is for competitors to mimic each other. This framework has proven useful to generations of political scientists even though Mr. Downs did not empirically test it and despite the fact that its main prediction, that candidates will take identical positions in elections, is clearly false. The model offered insight into why candidates move toward the center in competitive elections
  • Likewise, the analysis of empirical data can be valuable even in the absence of a grand theoretical model. Did the welfare reform championed by Bill Clinton in the 1990s reduce poverty? Are teenage employees adversely affected by increases in the minimum wage?
  • Answering such questions about the effects of public policies does not require sweeping theoretical claims, just careful attention to the data.
  • theories are like maps: the test of a map lies not in arbitrarily checking random points but in whether people find it useful to get somewhere.
  • Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,” “experiment,” “law”) evocative of physics and chemistry.
  • The ideal of hypothetico-deductivism is flawed for many reasons. For one thing,

Why Study History? (1985) | AHA - 0 views

  • Isn't there quite enough to learn about the world today? Why add to the burden by looking at the past
  • Historical knowledge is no more and no less than carefully and critically constructed collective memory. As such it can both make us wiser in our public choices and more richly human in our private lives.
  • Without individual memory, a person literally loses his or her identity, and would not know how to act in encounters with others. Imagine waking up one morning unable to tell total strangers from family and friends!
  • ...37 more annotations...
  • Collective memory is similar, though its loss does not immediately paralyze everyday private activity. But ignorance of history-that is, absent or defective collective memory-does deprive us of the best available guide for public action, especially in encounters with outsider
  • Often it is enough for experts to know about outsiders, if their advice is listened to. But democratic citizenship and effective participation in the determination of public policy require citizens to share a collective memory, organized into historical knowledge and belief
  • This value of historical knowledge obviously justifies teaching and learning about what happened in recent times, for the way things are descends from the way they were yesterday and the day before that
  • in fact, institutions that govern a great deal of our everyday behavior took shape hundreds or even thousands of years ago
  • Only an acquaintance with the entire human adventure on earth allows us to understand these dimensions of contemporary reality.
  • it follows that study of history is essential for every young person.
  • Collective memory is quite the same. Historians are always at work reinterpreting the past, asking new questions, searching new sources and finding new meanings in old documents in order to bring the perspective of new knowledge and experience to bear on the task of understanding the past.
  • what we know and believe about history is always changing. In other words, our collective, codified memory alters with time just as personal memories do, and for the same reasons.
  • skeptics are likely to conclude that history has no right to take student time from other subjects. If what is taught today is not really true, how can it claim space in a crowded school curriculum?
  • what if the world is more complicated and diverse than words can ever tell? What if human minds are incapable of finding' neat pigeon holes into which everything that happens will fit?
  • What if we have to learn to live with uncertainty and probabilities, and act on the basis of the best guesswork we are capable of?
  • Then, surely, the changing perspectives of historical understanding are the very best introduction we can have to the practical problems of real life. Then, surely, a serious effort to understand the interplay of change and continuity in human affairs is the only adequate introduction human beings can have to the confusing flow of events that constitutes the actual, adult world.
  • Memory is not something fixed and forever. As time passes, remembered personal experiences take on new meanings.
  • Early in this century, teachers and academic administrators pretty well agreed that two sorts of history courses were needed: a survey of the national history of the United States and a survey of European history.
  • Memory, indeed, makes us human. History, our collective memory, carefully codified and critically revised, makes us social, sharing ideas and ideals with others so as to form all sorts of different human groups
  • The varieties of history are enormous; facts and probabilities about the past are far too numerous for anyone to comprehend them all. Every sort of human group has its own histor
  • Where to start? How bring some sort of order to the enormous variety of things known and believed about the past?
  • Systematic sciences are not enough. They discount time, and therefore oversimplify reality, especially human reality.
  • This second course was often broadened into a survey of Western civilization in the 1930s and 1940s
  • But by the 1960s and 1970s these courses were becoming outdated, left behind by the rise of new kinds social and quantitative history, especially the history of women, of Blacks, and of other formerly overlooked groups within the borders of the United States, and of peoples emerging from colonial status in the world beyond our borders.
  • much harder to combine old with new to make an inclusive, judiciously balanced (and far less novel) introductory course for high school or college students.
  • But abandoning the effort to present a meaningful portrait of the entire national and civilizational past destroyed the original justification for requiring students to study history
  • Competing subjects abounded, and no one could or would decide what mattered most and should take precedence. As this happened, studying history became only one among many possible ways of spending time in school.
  • The costs of this change are now becoming apparent, and many concerned persons agree that returning to a more structured curriculum, in which history ought to play a prominent part, is imperative.
  • three levels of generality seem likely to have the greatest importance for ordinary people.
  • First is family, local, neighborhood history
  • Second is national history, because that is where political power is concentrated in our time.
  • Last is global history, because intensified communications make encounters with all the other peoples of the earth increasingly important.
  • Other pasts are certainly worth attention, but are better studied in the context of a prior acquaintance with personal-local, national, and global history. That is because these three levels are the ones that affect most powerfully what all other groups and segments of society actually do.
  • National history that leaves out Blacks and women and other minorities is no longer acceptable; but American history that leaves out the Founding Fathers and the Constitution is not acceptable either. What is needed is a vision of the whole, warts and all.
  • the study of history does not lead to exact prediction of future events. Though it fosters practical wisdom, knowledge of the past does not permit anyone to know exactly what is going to happen
  • Consequently, the lessons of history, though supremely valuable when wisely formulated, become grossly misleading when oversimplifiers try to transfer them mechanically from one age to another, or from one place to another.
  • Predictable fixity is simply not the human way of behaving. Probabilities and possibilities-together with a few complete surprises-are what we live with and must learn to expect.
  • Second, as acquaintance with the past expands, delight in knowing more and more can and often does become an end in itself.
  • On the other hand, studying alien religious beliefs, strange customs, diverse family patterns and vanished social structures shows how differently various human groups have tried to cop
  • Broadening our humanity and extending our sensibilities by recognizing sameness and difference throughout the recorded past is therefore an important reason for studying history, and especially the history of peoples far away and long ago
  • For we can only know ourselves by knowing how we resemble and how we differ from others. Acquaintance with the human past is the only way to such self knowledge.

Why the modern world is bad for your brain | Science | The Guardian - 0 views

  • Our brains are busier than ever before. We’re assaulted with facts, pseudo facts, jibber-jabber, and rumour, all posing as information. Trying to figure out what you need to know and what you can ignore is exhausting.
  • Our smartphones have become Swiss army knife–like appliances that include a dictionary, calculator, web browser, email, Game Boy, appointment calendar, voice recorder, guitar tuner, weather forecaster, GPS, texter, tweeter, Facebook updater, and flashlight.
  • But there’s a fly in the ointment. Although we think we’re doing several things at once, multitasking, this is a powerful and diabolical illusion.
  • ...12 more annotations...
  • When people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost in doing so.”
  • Even though we think we’re getting a lot done, ironically, multitasking makes us demonstrably less efficient.
  • Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation.
  • The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted.
  • Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.
  • His research found that being in a situation where you are trying to concentrate on a task, and an email is sitting unread in your inbox, can reduce your effective IQ by 10 points.
  • Wilson showed that the cognitive losses from multitasking are even greater than the cognitive losses from pot‑smoking.
  • If students study and watch TV at the same time, for example, the information from their schoolwork goes into the striatum, a region specialised for storing new procedures and skills, not facts and ideas. Without the distraction of TV, the information goes into the hippocampus, where it is organised and categorised in a variety of ways, making it easier to retrieve.
  • All this activity gives us a sense that we’re getting things done – and in some cases we are. But we are sacrificing efficiency and deep concentration when we interrupt our priority activities with email.
  • This uncertainty wreaks havoc with our rapid perceptual categorisation system, causes stress, and leads to decision overload. Every email requires a decision! Do I respond to it? If so, now or later? How important is it? What will be the social, economic, or job-related consequences if I don’t answer, or if I don’t answer right now?
  • A lever in the cage allowed the rats to send a small electrical signal directly to their nucleus accumbens. Do you think they liked it? Boy how they did! They liked it so much that they did nothing else. They forgot all about eating and sleeping. Long after they were hungry, they ignored tasty food if they had a chance to press that little chrome bar;
  • But remember, it is the dumb, novelty-seeking portion of the brain driving the limbic system that induces this feeling of pleasure, not the planning, scheduling, higher-level thought centres in the prefrontal cortex. Make no mistake: email-, Facebook- and Twitter-checking constitute a neural addiction.

Amazon Targets Medicaid Recipients as It Widens War for Low-Income Shoppers - WSJ - 0 views

  • The online retail giant said Wednesday that it will extend its $5.99 monthly Prime membership to the roughly 20% of the U.S. population that is signed up for Medicaid.

  • What is the role of governments in promoting economic growth?
  • What can governments do to seize the opportunities of globalization, while minimizing its downsides?
  • we have to recognize that the tension between markets and government is not new. In fact, it has been the central issue in the evolution of political economy over the last 200 years.
  • Government intervention was necessary to boost aggregate demand during periods of high unemployment.
  • Phase One: The rise of the market
  • The “rise of the market” began in the late 18th century, shaped by the writings of Adam Smith and David Ricardo. The “invisible hand” of the market guided supply and demand toward equilibrium and efficiency.
  • This phase came to an end in the 1930s, when the concept of self-correcting markets collapsed under the weight of the Great Depression.
  • Falling prices, instead of bringing demand and supply into equilibrium,
  • Phase Two: The rise of government
  • markets were inherently unstable. Left on their own, they may not always self-correct
  • There have been three distinct phases in this evolution.
  • The 1940s also saw the advent of the welfare state.
  • The welfare state was enabled through redistributive taxation and government regulation.
  • Phase Three: The return of the market
  • This phase began with growing disenchantment with government’s ability to deliver and was driven forward mainly by U.S.-based economists
  • The stagflation of the 1970s — persistently high inflation and unemployment — called into question the ability of governments to fine-tune the economy. Meanwhile, the welfare state began to impose an unsustainable fiscal burden,
  • Friedrich Hayek and Milton Friedman led the charge against “Big Government.” They argued eloquently how an overreaching government dulled the fundamental human instincts that power the capitalist system:
  • In the 1980s, U.S. President Ronald Reagan and UK Prime Minister Margaret Thatcher reduced taxes, deregulated industries, privatized state-owned enterprises, curbed union power, and scaled back welfare programs. The global economy boomed.
  • Phase Four: Balancing markets and governments
  • The financial crisis has revealed significant imperfections in market mechanisms: information asymmetry, moral hazard, systemic risks and behavioral or nonrational motivators of choice.
  • In a more globalized and complex economy, governments have fewer levers to pull
  • It has also revealed the inherent limitations of governmen
  • Neither market fundamentalism nor central planning has worked.
  • Yet one thing is certain: The choice is not between big government and small government. It is about creating effective government. What matters is what governments do, not how big they are.

Next stop for free college: Cal State University? | CalMatters - 0 views

  • In yet another push to make higher education more accessible in California, a bill filed in the state Legislature last week would extend the state’s tuition-free college guarantee to four years — and beyond community college — for some students, making it one of the most generous programs in the nation.
  • “If we want a truly debt-free education, you’ve got to begin that conversation by cutting tuition and fees,” he said. “If you don’t tell these kids every single day that you’re going to go to college, it may not be a reality.”
  • While the bill does not contain a cost estimate, the price tag would likely be “in the low hundreds of millions,” said Francisco Rodriguez, chancellor of the Los Angeles Community College District, a bill sponsor. (The overall state budget proposed by Gov. Gavin Newsom last week totaled $222 billion, with nearly $4 billion earmarked for Cal State next year.)

  • Among free college programs nationwide, New York’s Excelsior Scholarship covers four years of tuition at the state’s public universities for students with family incomes of $125,000 or less, provided they attend full-time and stay in the area after graduation. But most state free college plans only pay for community college, which helps contain cost and draw bipartisan support.
  • If passed, it could also increase demand for spots at the already-overcrowded California State University, said Gail Yen, a policy analyst at California Competes, a nonpartisan higher education think tank.

Why first impressions matter even more for groups - Quartz at Work - 0 views

  • First impressions are powerful. We all remember being instantly drawn to or put off by someone we’ve just met.
  • imagine you see a video of a skateboarder landing an especially impressive trick. If she’s the first of a group of competitors, you’ll probably assume the rest of the group is equally skilled. But if you know this skater standout was the third to compete, it’s less likely to influence your impression of the rest of the group.

  • “The sequence, no matter how arbitrary, is going to have some influence on your judgment,” Touré-Tillery says. “And this happens without you knowing that it’s having that kind of influence on your judgment.”
  • The researchers were struck by the power of the first-member heuristic. “It’s a very strong effect statistically,” she says, and one that seems to endure across contexts. So the researchers wanted to understand if there were any circumstances in which people would stop relying on this mental shortcut.
  • “This is something that we want to be mindful of, that thinking of someone as the first member of the group can influence what you then expect the rest of the group to do. And expectations are often self-fulfilling.”

How Navy SEALs Conquer Fear and Anxiety - SEALFIT - 1 views

Study: People Want Power Because They Want Autonomy - The Atlantic - 0 views

  • But a new study suggests that people who desire power are mostly looking to control one thing—themselves.
  • “Power as influence is expressed in having control over others, which could involve responsibility for others,” they write. “In contrast, power as autonomy is a form of power that allows one person to ignore and resist the influence of others and thus to shape one’s own destiny.” Their question: Which of those things, influence or autonomy, would satisfy people’s desire for power?
  • But within the assistants, those who felt that lack of autonomy most strongly were more likely to desire power. Feeling the lack of influence didn’t have the same effect.
  • ...3 more annotations...
  • All told, this research indicates that the desire for power may be somewhat misplaced: Generally, when people say they want power, what they really want is autonomy. And when they get that autonomy, they tend to stop wanting power.
  • psychological theory that suggests autonomy is one of humans’ basic psychological needs, along with relatedness and competence. Influence is not a need under this theory.
  • The study references real leaders like Napoleon, Caesar, Obama, and Putin, and fictional ones like Darth Vader and Sauron, and says, “The sense of autonomy of these powerful individuals is not as visible: It is reflected in the absence of constraint, plans not being thwarted, and ambitions not being frustrated—an absence which remains unobserved.”

Reading is fundamental -- to the family's happiness - CNN - 0 views

  • The value of reading to our kids -- for them and us -- is reinforced by the growing body of research on the topic. Just last week, a meta-analysis of 19 studies published in the journal Pediatrics found that reading aloud was significantly beneficial to children and their parents.In most of the studies -- which involved more than 3,000 families -- the parents were assessed as well as their kids, and reading aloud appeared to strengthen parents' feelings of competence, improve the quality of their relationships with their children and even reduce parental stress or depression.
  • mproving a child's reading skills and cognitive ability is important to their success in school, work and life. "If you are going to get anywhere in life," Roald Dahl is credited with saying, "you have to read a lot of books."The conversations children have around themes and ideas in books help them make sense of the world. And it's a joyful way to connect and be close with your kid. While reading in bed, my daughters and I lie next to each other, sometimes leaning into one other. We laugh and are surprised together and have deep conversations sparked by the novels. It's as high a quality as quality time gets.
  • Turning book reading into a ritual is as simple as repetition paired with a certain time or situation. Reading to kids just before bed is popular because routine makes for easier bedtimes as well -- a twofer!

Having an elder brother is associated with slower language development -- ScienceDaily - 0 views

  • Intuitively, it is tempting to think that a child who has an elder brother or sister will grow up in a stimulating linguistic environment and will develop their language skills faster than the family's firstborn. However, several studies have shown the contrary: the acquisition of language in a child with an elder sibling is reported to be slower than a child who has none.
  • More than 1000 children have been followed from birth to five and a half years old in the mother-child cohort EDEN.* Their language skills were evaluated at 2, 3 and 5.5 years old by tests measuring several aspects of language, such as vocabulary, syntax and verbal reasoning
  • Children who have an elder brother had on average a two-month delay in language development compared with children with an elder sister.
  • ...2 more annotations...
  • The first is that elder sisters, in being more willing to talk to their younger siblings than brothers, may compensate for their parents being less available. Another hypothesis would be that elder sisters compete less than elder brothers for parental attention.
  • Though this study cannot separate these two hypotheses, it does show that early language development in a younger sibling tends to be slower when the elder is a boy.

Boris Johnson's blundering was political genius. But now that moment has passed | Steph... - 0 views

  • One of the most potent and enduring myths in our society is that leadership is reducible to the power of the leader. A few special individuals are blessed with special qualities that set them apart from the rest of us and entitle them to rule. As Thomas Carlyle asserted, “Universal history … is at bottom the history of the great men who have worked here.” If only we could isolate the qualities that make these leaders exceptional.
  • Such ideas launched numerous studies that sought to find personality characteristics that predict leadership success – none of them particularly fruitful.
  • such an approach misses a very obvious point: leaders only achieve anything through their followers, and “great man” theories write the followers out of history.
  • ...8 more annotations...
  • And leaders are never just leaders, they are always leaders of a particular social group – a nation, a political party, a religion
  • leadership is a group process: and, more specifically, it is the cultivation of a “we” relationship between leaders and followers.
  • Effective leadership, then, is not about what separates the leader from others. It is about what brings the leader together with group members and allows him or her to represent them
  • n effective leader is one who is seen to be one of us, to work for us and to achieve the things we value. That isn’t about being ordinary or typical. It is about being prototypical – of representing the values and the qualities that make our group distinctive.
  • In addition, effective leaders are not passive. They actively craft the group narrative and their own personal narrative to make the two mesh: they are skilled entrepreneurs of identity.
  • Hence, no given set of qualities will guarantee effective leadership, for these will change according to the identity of the group.
  • the performative politics of populism can backfire by making one unrepresentative as the groupings change. In the midst of a pandemic where the widest possible compliance to restrictive measures is necessary, the nation and its communities must be unified and inclusive. The inherently divisive categories of populism are no longer tenable.
  • Moreover, we need competent governance to get us through, rather than insurgent incompetence to get our votes. In this global crisis, our blundering prime minister is no longer of the group, nor for the group, and certainly not achieving what the group needs.

Free Speech and Civic Virtue between "Fake News" and "Wokeness" | History News Network - 1 views

  • none of these arguments reaches past adversarial notions of democracy. They all characterize free speech as a matter of conflicting rights-claims and competing factions.
  • As long as political polarization precludes rational consensus, she argues, we are left to “[make] personal choices and pronouncements regarding what we are willing (or unwilling) to tolerate, in an attempt to slightly nudge the world in our preferred direction.” Notably, she makes no mention of how we might discern the validity of those preferences or how we might arbitrate between them in cases of conflict.
  • Free speech advocates are hypocritical or ignore some extenuating context, they claim, while those stifling disagreeable or offensive views are merely rectifying past injustices or paying their opponents back in kind, operating practically in a flawed public sphere.
  • ...16 more annotations...
  • It is telling, however, that the letter’s critics focus on speakers and what they deserve to say far more than the listening public and what we deserve to hear
  • In Free Speech and Its Relation to Self-Government (1948), Meikeljohn challenges us to approach public discourse from the perspective of the “good man”: that is to say, the virtuous citizen
  • One cannot appreciate the freedom of speech, he writes, unless one sees it as an act of collective deliberation, carried out by “a man who, in his political activities, is not merely fighting for what…he can get, but is eagerly and generously serving the common welfare”
  • Free speech is not only about discovering truth, or encouraging ethical individualism, or protecting minority opinions—liberals’ usual lines of defense—it is ultimately about binding our fate to others’ by “sharing” the truth with our fellow citizens
  • Sharing truth requires mutual respect and a jealous defense of intellectual freedom, so that “no idea, no opinion, no doubt, no belief, no counter belief, no relevant information” is withheld from the electorate
  • For their part, voters must judge these arguments individually, through introspection, virtue, and meditation on the common good. 
  • The “marketplace of ideas” is dangerous because it relieves citizens of exactly these duties. As Meikeljohn writes:   As separate thinkers, we have no obligation to test our thinking, to make sure that it is worthy of a citizen who is one of the ‘rulers of the nation.’ That testing is to be done, we believe, not by us, but by ‘the competition of the market.
  • this is precisely the sort of self-interested posturing that many on the Left resent in their opponents, but which they now propose to embrace as their own, casually accepting the notion that their fellow citizens are incapable of exercising public reason or considering alternative viewpoints with honesty, bravery, humility, and compassion. 
  • In practice, curtailing public speech is likely to worsen polarization and further empower dominant cultural interests. As an ideal (or a lack thereof), it undermines the intelligibility and mutual respect that form the very basis of citizenship.
  • political polarization has induced Americans to abandon “truth-directed methods of persuasion”—such as argumentation and evidence—for a form of non-rational “messaging,” in which “every speech act is classified as friend or foe… and in which very little faith exists as to the rational faculties of those being spoken to.”
  • “In such a context,” she writes, “even the cry for ‘free speech’ invites a nonliteral interpretation, as being nothing but the most efficient way for its advocates to acquire or consolidate power.”
  • Segments of the Right have pushed this sort of political messaging to its cynical extremes—taking Donald Trump’s statements “seriously but not literally” or taking antagonistic positions simply to “own the libs.”
  • Rather than assuming the supremacy of our own opinions or aspersing the motives of those with whom we disagree, our duty as Americans is to think with, learn from, and correct each other.
  • some critics of the Harper’s letter seem eager to reduce all public debate to a form of power politics
  • Trans activist Julia Serano merely punctuates the tendency when she writes that calls for free speech represent a “misconception that we, as a society, are all in the midst of some grand rational debate, and that marginalized people simply need to properly plea our case for acceptance, and once we do, reason-minded people everywhere will eventually come around. This notion is utterly ludicrous.”
  • one could say that critics of the Harper’s letter take the “bad man” as their unit of analysis. By their lights, all participants in public debate are prejudiced, particular, and self-interested
