The history of inequality (by Peter Turchin) - 0 views

  • Today, the top one per cent of incomes in the United States accounts for one fifth of US earnings. The top one per cent of fortunes holds two-fifths of the total wealth.
  • As the Congressional Budget Office concluded in 2011: ‘the precise reasons for the rapid growth in income at the top are not well understood’.
  • In his book Wealth and Democracy (2002), Kevin Phillips came up with a useful way of thinking about the changing patterns of wealth inequality in the US.
  • ...67 more annotations...
  • He looked at the net wealth of the nation’s median household and compared it with the size of the largest fortune in the US. The ratio of the two figures provided a rough measure of wealth inequality, and that’s what he tracked, touching down every decade or so from the turn of the 19th century all the way to the present.
  • We found repeated back-and-forth swings in demographic, economic, social, and political structures
  • From 1800 to the 1920s, inequality increased more than a hundredfold.
  • Then came the reversal: from the 1920s to 1980, it shrank back to levels not seen since the mid-19th century.
  • From 1980 to the present, the wealth gap has been on another steep, if erratic, rise. Commentators have called the period from 1920s to 1970s the ‘great compression’. The past 30 years are known as the ‘great divergence’.

      I'd like to pull this citation and superimpose another period-chart onto my timeline.
  • when looked at over a long period, the development of wealth inequality in the US appears to be cyclical. And if it’s cyclical, we can predict what happens next.
  • Does observing just one and a half cycles really show that there is a regular pattern in the dynamics of inequality? No, by itself it doesn’t.
  • In our book Secular Cycles (2009), Sergey Nefedov and I applied the Phillips approach to England, France and Russia throughout both the medieval and early modern periods, and also to ancient Rome.
  • And the cycles of inequality were an integral part of the overall motion.
  • Cycles in the real world are chaotic, because complex systems such as human societies have many parts that are constantly moving and influencing each other.
  • Understanding (and perhaps even forecasting) such trend-reversals is at the core of the new discipline of cliodynamics, which looks at history through the lens of mathematical modelling.

      Cliodynamics - Another thing to learn a bit more about.
  • First, we need to think about jobs.
  • One of the most important forces affecting the labour supply in the US has been immigration
  • it turns out that immigration, as measured by the proportion of the population who were born abroad, has changed in a cyclical manner just like inequality.
  • Another reason why the labour supply in the US went up in the 19th century is, not to put too fine a point on it, sex.
  • This connection between the oversupply of labour and plummeting living standards for the poor is one of the more robust generalisations in history.
  • The population of England doubled between 1150 and 1300.
  • causing the population of London to balloon from 20,000 to 80,000.
  • fourfold increase in food prices and a halving of real wages.
  • when a series of horrible epidemics, starting with the Black Death of 1348, carried away more than half of the population, the same dynamic ran in reverse.
  • The tug of war between the top and typical incomes doesn’t have to be a zero-sum game, but in practice it often is
  • Much the same pattern can be seen during the secular cycle of the Roman Principate.
  • Naturally, the conditions affecting the labour supply were different in the second half of the 20th century in the US. An important new element was globalisation
  • an oversupply of labour tends to depress wages for the poorer section of the population. And just as in Roman Egypt, the poor in the US today eat more energy-dense foods — bread, pasta, and potatoes — while the wealthy eat more fruit and drink wine.
  • Falling wages isn’t the only reason why labour oversupply leads to inequality. As the slice of the economic pie going to employees diminishes, the share going to employers goes up.
  • And so in 13th-century England, as the overall population doubles, we find landowners charging peasants higher rents and paying less in wages: the immiseration of the general populace translates into a Golden Age for the aristocrats.
  • the number of knights and esquires tripled between 1200 and 1300.
  • Only the gentry drank wine, and around 1300, England imported 20,000 tuns or casks of it from France per year. By 1460, this declined to only 5,000.
  • In the US between around 1870 and 1900, there was another Golden Age for the elites, appropriately called the Gilded Age.
  • And just like in 13th-century England, the total number of the wealthy was shooting up. Between 1825 and 1900, the number of millionaires (in constant 1900 dollars) went from 2.5 per million of the population to 19 per million.
  • In our current cycle, the proportion of decamillionaires (those whose net worth exceeds 10 million in 1995 dollars) grew tenfold between 1992 and 2007 — from 0.04 to 0.4 per cent of the US population.
  • On the face of it, this is a wonderful testament to merit-based upward mobility. But there are side effects. Don’t forget that most people are stuck with stagnant or falling real wages. Upward mobility for a few hollows out the middle class and causes the social pyramid to become top-heavy.
  • As the ranks of the wealthy swell, so too do the numbers of wealthy aspirants for the finite supply of political positions.
  • The civil wars of the first century BC, fuelled by a surplus of politically ambitious aristocrats, ultimately caused the fall of the Republic and the establishment of the Empire.
  • So far I have been talking about the elites as if they are all the same. But they aren’t: the differences within the wealthiest one per cent are almost as stark as the difference between the top one per cent and the remaining 99.
  • very intense status rivalry
  • Archaeology confirms a genuine and dramatic shift towards luxury.
  • Social Darwinism took off during the original Gilded Age, and Ayn Rand (who argued that altruism is evil) has grown astonishingly popular during what we might call our Second Gilded Age.
  • Twilight of the Elites (2012): ‘defenders of the status quo invoke a kind of neo-Calvinist logic by saying that those at the top, by virtue of their placement there, must be the most deserving’. By the same reasoning, those at the bottom are not deserving. As such social norms spread, it becomes increasingly easy for CEOs to justify giving themselves huge bonuses while cutting the wages of workers.
  • Labour markets are especially sensitive to cultural norms about what is fair compensation, so prevailing theories about inequality have practical consequences.
  • the US political system is much more attuned to the wishes of the rich than to the aspirations of the poor.
  • Inverse relationship between well-being and inequality in American history. The peaks and valleys of inequality (in purple) represent the ratio of the largest fortunes to the median wealth of households (the Phillips curve). The blue-shaded curve combines four measures of well-being: economic (the fraction of economic growth that is paid to workers as wages), health (life expectancy and the average height of native-born population), and social optimism (the average age of first marriage, with early marriages indicating social optimism and delayed marriages indicating social pessimism).
  • In some historical periods it worked primarily for the benefit of the wealthy. In others, it pursued policies that benefited the society as a whole. Take the minimum wage, which grew during the Great Compression era and declined (in real terms) after 1980.
  • The top marginal tax rate was 68 per cent or higher before 1980; by 1988 it declined to 28 per cent.
  • In one era, government policy systematically favoured the majority, while in another it favoured the narrow interests of the wealthy elites. This inconsistency calls for explanation.
  • How, though, can we account for the much more broadly inclusive policies of the Great Compression era? And what caused the reversal that ended the Gilded Age and ushered in the Great Compression? Or the second switch, which took place around 1980?
  • Unequal societies generally turn a corner once they have passed through a long spell of political instability.
  • We see this shift in the social mood repeatedly throughout history — towards the end of the Roman civil wars (first century BC), following the English Wars of the Roses (1455-85), and after the Fronde (1648-53), the final great outbreak of violence that had been convulsing France since the Wars of Religion began in the late 16th century.
  • Put simply, it is fear of revolution that restores equality. And my analysis of US history in a forthcoming book suggests that this is precisely what happened in the US around 1920.
  • The worst incident in US labour history was the West Virginia Mine War of 1920—21, culminating in the Battle of Blair Mountain.
  • Although it started as a workers’ dispute, the Mine War eventually turned into the largest armed insurrection that the US has ever seen, the Civil War excepted. Between 10,000 and 15,000 miners armed with rifles battled against thousands of strikebreakers and sheriff deputies.
  • Quantitative data indicate that this period was the most violent in US history, second only to the Civil War. It was much, much worse than the 1960s.
  • The US, in short, was in a revolutionary situation, and many among the political and business elites realised it.
  • The US elites entered into an unwritten compact with the working classes. This implicit contract included the promise that the fruits of economic growth would be distributed more equitably among both workers and owners. In return, the fundamentals of the political-economic system would not be challenged (no revolution).
  • The deal allowed the lower and upper classes to co-operate in solving the challenges facing the American Republic — overcoming the Great Depression, winning the Second World War, and countering the Soviet threat during the Cold War.
  • while making such ‘categorical inequalities’ worse, the compact led to a dramatic reduction in overall economic inequality.
  • The co-operating group was mainly native-born white Protestants. African-Americans, Jews, Catholics and foreigners were excluded or heavily discriminated against.
  • When Barry Goldwater campaigned on a pro-business, anti-union and anti-big government platform in the 1964 presidential elections, he couldn’t win any lasting support from the corporate community. The conservatives had to wait another 16 years for their triumph.
  • But by the late 1970s, a new generation of political and business leaders had come to power. To them the revolutionary situation of 1919-21 was just history. In this they were similar to the French aristocrats on the eve of the French Revolution, who did not see that their actions could bring down the Ancien Régime — the last great social breakdown, the Fronde, being so far in the past.

      This heavily mirrors many aspects of Strauss & Howe's observations. Namely that generational cohorts roughly conform to archetypes precisely *because* memory of prior situations moves from accessible-memory (in those who have it) to history/myth once those who remember it have died.
  • It is no coincidence that the life of Communism (from the October Revolution in Russia in 1917 to the fall of the Berlin Wall in 1989) coincides almost perfectly with the Great Compression era.
  • when Communism collapsed, its significance was seriously misread. It’s true that the Soviet economy could not compete with a system based on free markets plus policies and norms that promoted equity.
  • Yet the fall of the Soviet Union was interpreted as a vindication of free markets, period. The triumphalist, heady atmosphere of the 1990s was highly conducive to the spread of Ayn Randism and other individualist ideologies. The unwritten social contract that had emerged during the New Deal and braved the challenges of the Second World War had faded from memory.
  • all of these trends are part of a complex and interlocking system. I don’t just mean that everything affects everything else; that would be vacuous.
  • Rather, that cliodynamic theory can tell us specifically how demographic, economic and cultural variables relate to one another, and how their interactions generate social change.
  • Cliodynamics also explains why historical reversals in such diverse areas as economics and culture happen at roughly similar times. The theory of secular cycles was developed using data from historical societies, but it looks like it can provide answers to questions about our own society.
  • Three years ago I published a short article in the science journal Nature. I pointed out that several leading indicators of political instability look set to peak around 2020.

      2020-2025 is a date-range that continues to pop up in my forecasting readings - and from quite a variety of sources.
  • In other words, we are rapidly approaching a historical cusp, at which the US will be particularly vulnerable to violent upheaval. This prediction is not a ‘prophecy’. I don’t believe that disaster is pre-ordained, no matter what we do. On the contrary, if we understand the causes, we have a chance to prevent it from happening. But the first thing we will have to do is reverse the trend of ever-growing inequality.
  •  
    "After thousands of scholarly and popular articles on the topic, one might think we would have a pretty good idea why the richest people in the US are pulling away from the rest. But it seems we don't. As the Congressional Budget Office concluded in 2011: 'the precise reasons for the rapid growth in income at the top are not well understood'. Some commentators point to economic factors, some to politics, and others again to culture. Yet obviously enough, all these factors must interact in complex ways. What is slightly less obvious is how a very long historical perspective can help us to see the whole mechanism."

How consciousness works - 0 views

  • I admit that the theory does not feel satisfying; but a theory does not need to be satisfying to be true.

      Somebody tattoo that on the back of everyone's eyelids.
  • And indeed, the theory might be able to explain a few other common myths that brains tell themselves. What about out-of-body experiences? The belief that awareness can emanate from a person’s eyes and touch someone else? That you can push on objects with your mind? That the soul lives on after the death of the body? One of the more interesting aspects of the attention schema theory is that it does not need to turn its back on such persistent beliefs. It might even explain their origin.
  • If awareness is a model of attention, how is it simplified? How is it inaccurate? Well, one easy way to keep track of attention is to give it a spatial structure — to treat it like a substance that flows from a source to a target.
  • ...17 more annotations...
  • Science commonly regards ghost-ish intuitions to be the result of ignorance, superstition, or faulty intelligence. In the attention schema theory, however, they are not simply ignorant mistakes. Those intuitions are ubiquitous among cultures because we humans come equipped with a handy, simplified model of attention. That model informs our intuitions.
  • The very existence of the out-of-body experience suggests that awareness is a computation and that the computation can be disrupted. Systems in the brain not only compute the information that I am aware, but also compute a spatial framework for it, a location, and a perspective. Screw up the computations, and I screw up my understanding of my own awareness.
  • a study by the psychologist Gerald Winer and colleagues at the University of Ohio in 2002 found that about half of American college students also think that we see because of rays that come out of the eyes.
  • Our culture, too, is riddled with the extramission theory.
  • Why should a physically inaccurate description of vision be so persistent? Perhaps because the brain constructs a simplified, handy model of attention in which there is such a thing as awareness, an invisible, intangible stuff that flows from inside a person out to some target object.
  • We come pre-equipped with that intuition, not because it is physically accurate but because it is a useful model.
  • Many of our superstitions — our beliefs in souls and spirits and mental magic — might emerge naturally from the simplifications and shortcuts the brain takes when representing itself and its world.
  • We have the ability to rise above our immediate intuitions and predispositions.
  • Most of us intuitively understand it to be an active thing: it helps us to decide what to do and when. And yet, at least some of the scientific work on consciousness has proposed the opposite, counter-intuitive view: that it doesn’t really do anything at all
  • It seems, therefore, that at least some of our conscious choices are rationalisations after the fact.
  • But if consciousness is a story we tell ourselves, why do we need it? Why are we aware of anything at all? Why not just be skilful automata, without the overlay of subjectivity? Some philosophers think we are automata and just don’t know it.
  • This idea that consciousness has no leverage in the world, that it’s just a rationalisation to make us feel better about ourselves, is terribly bleak.
  • It is not a theory about the uselessness or non-being of consciousness, but about its central importance. Why did an awareness of stuff evolve in the first place?
  • Because it had a practical benefit.
  • the attention schema theory is in agreement with the common intuition: consciousness plays an active role in guiding our behaviour. It is not merely an aura that floats uselessly in our heads. It is a part of the executive control system.
  • To attribute awareness to oneself, to have that computational ability, is the first step towards attributing it to others. That, in turn, leads to a remarkable evolutionary transition to social intelligence.
  • We live embedded in a matrix of perceived consciousness. Most people experience a world crowded with other minds, constantly thinking and feeling and choosing.

Charles, Prince of Piffle - 0 views

  • We have known for a long time that Prince Charles' empty sails are so rigged as to be swelled by any passing waft or breeze of crankiness and cant. He fell for the fake anthropologist Laurens van der Post. He was bowled over by the charms of homeopathic medicine. He has been believably reported as saying that plants do better if you talk to them in a soothing and encouraging way. But this latest departure promotes him from an advocate of harmless nonsense to positively sinister nonsense.
  • The heir to the throne seems to possess the ability to surround himself—perhaps by some mysterious ultramagnetic force?—with every moon-faced spoon-bender, shrub-flatterer, and water-diviner within range.
  • So this is where all the vapid talk about the "soul" of the universe is actually headed. Once the hard-won principles of reason and science have been discredited, the world will not pass into the hands of credulous herbivores who keep crystals by their sides and swoon over the poems of Khalil Gibran. The "vacuum" will be invaded instead by determined fundamentalists of every stripe who already know the truth by means of revelation and who actually seek real and serious power in the here and now.

Absence of Mind by Marilynne Robinson - 0 views

  • At the same time as the western scientific revolution empowered human beings, opened new worlds and broadened their horizons, it progressively punctured their self-esteem.
  • Increasingly, luminaries of modern thought have told us that our minds are not to be trusted: that even though we thought we were standing on a static Earth, our planet was moving very fast indeed; that we could never be sure that our ideas corresponded to objective reality outside our own heads; that some of our noblest ideals were simply the product of repressed sexuality; and that, finally, we are deluded if we imagine that we "think", "reason," "learn" or "choose". Our minds are simply a passive conduit for an unknown, indifferent force.
  • This disdainful "hermeneutics of condescension" cannot function outside of a narrow definition of relative data. Nowhere is this more apparent than in the positivist critique of religion.

  • Robinson takes the science-versus-religion debate a stage further. More significant than this jejune attack on faith, she argues, is the disturbing fact that "the mind, as felt experience, has been excluded from important fields of modern thought" and as a result "our conception of humanity has shrunk".

Psychedelic Drugs Show Promise as Anti-Depressants - 0 views

  • Ketamine—a powerful anesthetic for humans and animals that lists hallucinations among its side effects and therefore is often abused under the name Special K—delivers rapid relief to chronically depressed patients, and researchers may now have discovered why. In fact, the latest evidence reinforces the idea that the psychedelic drug could be the first new drug in decades to lift the fog of depression.
  • More specifically, as the researchers report in the August 20 issue of Science, ketamine seems to stimulate a biochemical pathway in the brain (known as mTOR) to strengthen synapses in a rat's prefrontal cortex—the region of the brain associated with thinking and personality in humans.
  • In fact, ketamine has shown promise at reducing the risk of suicide and is currently being tested in humans for effectiveness in treating bipolar disorder and addiction.
  • ...1 more annotation...
  • Regardless, it is unlikely that ketamine, psilocybin or any of these psychedelics would be used directly, because of their hallucinogenic and other side effects.

The North Korean Nuclear Test and Geopolitical Reality - 0 views

  • Even before an atomic bomb was first detonated on July 16, 1945, both the scientists and engineers of the Manhattan Project and the U.S. military struggled with the implications of the science that they pursued.
  • understanding the implications of the atomic bomb was largely a luxury that would have to wait
  • But perhaps the most surprising aspect of the advent of the nuclear age is how little actually changed.
  • ...9 more annotations...
  • Wars of immense risk are born of desperation. In World War II, both Nazi Germany and Imperial Japan took immense geostrategic gambles — and lost — but knowingly took the risk because of untenable geopolitical circumstances.
  • By comparison, the postwar United States and Soviet Union were geopolitically secure. Washington had come into its own as a global power secured by the buffer of two oceans, while Moscow enjoyed the greatest strategic depth it had ever known.
  • What was supposed to be the ultimate weapon has proved too risky and too inappropriate as a weapon ever to see the light of day again. Though nuclear weapons certainly played a role in the strategic calculus of the Cold War, they had no relation to a military strategy that anyone could seriously contemplate. Militaries, of course, had war plans and scenarios and target sets. But outside this world of role-play Armageddon, neither side was about to precipitate a global nuclear war.
  • The history of proliferation shows that few countries actually ever decide to pursue nuclear weapons. Obtaining them requires immense investment (and the more clandestine the attempt, the more costly the program becomes), and the ability to focus and coordinate a major national undertaking over time.
  • A nuclear North Korea, the world has now seen, is not sufficient alone to risk renewed war on the Korean Peninsula.
  • Iran is similarly defended. It can threaten to close the Strait of Hormuz, to launch a barrage of medium-range ballistic missiles at Israel, and to use its proxies in Lebanon and elsewhere to respond with a new campaign of artillery rocket fire, guerrilla warfare and terrorism.
  • In other words, some other deterrent (be it conventional or unconventional) against attack is a prerequisite for a nuclear program, since powerful potential adversaries can otherwise move to halt such efforts.
  • Despite how frantic the pace of nuclear proliferation may seem at the moment, the true pace of the global nuclear dynamic is slowing profoundly. With the Comprehensive Test Ban Treaty already effectively in place (though it has not been ratified), the pace of nuclear weapons development has already slowed and stabilized dramatically.
  • Nuclear arms are better understood as an insurance policy, one that no potential aggressor has any intention of steering afoul of. Without practical military or political use, they remain held in reserve — where in all likelihood they will remain for the foreseeable future.

In defence of equality - 0 views

  • In our book The Spirit Level, Kate Pickett and I demonstrated that, first, many problems which are more prevalent lower down the social ladder are worse in societies with bigger income differences, and second, that almost everyone would benefit from reduced inequality.

  • While Snowdon is described as a “public health researcher,” in actual fact he has no public health qualifications and appears never to have published research in a peer-reviewed journal.

  • What The Spirit Level shows is that more equal societies enjoy better physical and mental health, lower homicide rates, fewer drug problems, fewer teenage births, higher maths and literacy scores, higher standards of child wellbeing, less bullying in schools, lower obesity rates, and fewer people in prison.
  • This left us with 23 rich market societies. We took our data from the best sources, such as the World Health Organisation, the United Nations and the World Bank. To double-check our findings, we then repeated our analyses for the 50 US states, to see if more unequal states showed the same consistent tendency to have more of these health and social problems. In almost 30 different cross-national analyses, we show the same tendency for one problem after another to be significantly worse in societies with bigger income differences.
  • Our critics also ignore the fact that these relationships have been widely demonstrated by other researchers. For example, as early as 1993 in the Criminal Justice Review, Hsieh and Pugh reviewed 34 studies of income inequality and violent crime and found a consistent correlation between the two—the authors estimated that it would need 58 new studies which found no effect in order to overturn this result. But studies since then have continued to confirm the link.
  • Similarly, our review of research papers published in peer-reviewed journals found that the tendency for health to be worse in more unequal societies has been demonstrated well over 100 times (see Social Science and Medicine, 2006).

Objectivism & "Metaphysics," Part 12 - 0 views

  • Since much of Rand’s metaphysics supports notions allied to common sense, it has more potential to, by leading people astray, exercise a baleful effect. These bad effects stem from three aspects of the Objectivist metaphysics:

America's "Natural Aristocracy" and the Triumph of Elite Reason - 0 views

  • Who should rule America, the revolutionary and Constitution-writing generations of American leaders asked? Should it be an aristocratic elite bred to rule by the best families of the land? Or should it be direct representatives of the people whose knowledge of statecraft might be slight but who were reflective of the popular will?

  • Forty years have passed since I was told to pay attention to early American history, and I finally understand why, petticoats and Pilgrims aside, it was such good advice. For it was their great concern about who should rule America that should now become ours.

    "Who should rule America, the revolutionary and Constitution-writing generations of American leaders asked? Should it be an aristocratic elite bred to rule by the best families of the land? Or should it be direct representatives of the people whose knowledge of statecraft might be slight but who were reflective of the popular will?"

Why All Indiscretions Appear Youthful - 0 views

  • In recent years psychologists have exposed the many ways that people subconsciously maintain and massage their moral self-image. They rate themselves as morally superior to the next person; overestimate the likelihood that they will act virtuously in the future; see their own good intentions as praiseworthy while dismissing others’ as inconsequential. And they soften their moral principles when doing a truly dirty job, like carrying out orders to exploit uninformed customers.
  • In piecing together a life story, the mind nudges moral lapses back in time and shunts good deeds forward, these new studies suggest — creating, in effect, a doctored autobiography.
  • “We can’t make up the past, but the brain has difficulty placing events in time, and we’re able to shift elements around,” said Anne E. Wilson, a social psychologist at Wilfrid Laurier University in Waterloo, Ontario. “The result is that we can create a personal history that, if not perfect, makes us feel we’re getting better and better.”

  • “People honestly view their past in a morally critical light, but at the same time they tend to emphasize that they have been improving,” the authors concluded.
  • But the mind seems particularly prone to backdating when it comes to cruel, greedy or cowardly acts — the physical evidence people weigh against stand-up deeds to judge whether they are as good as their parents told them they were. In a 2001 paper titled “From Chump to Champ,” Dr. Wilson and Michael Ross of the University of Waterloo demonstrated in a series of experiments that young adults described their teenage selves in far more negative terms than they did their current selves, often skewering their past judgment.
  • “The weirdest thing about reading about all these bad moral choices,” Dr. Escobedo said, “is that it makes you kind of feel good about yourself. Just seeing how everyone makes mistakes and regrets not doing what was morally right: It makes you feel more attached to humanity.”

Google Cars Drive Themselves, in Traffic - 0 views

  •  
    "Autonomous cars are years from mass production, but technologists who have long dreamed of them believe that they can transform society as profoundly as the Internet has. Robot drivers react faster than humans, have 360-degree perception and do not get distracted, sleepy or intoxicated, the engineers argue. They speak in terms of lives saved and injuries avoided - more than 37,000 people died in car accidents in the United States in 2008. The engineers say the technology could double the capacity of roads by allowing cars to drive more safely while closer together. Because the robot cars would eventually be less likely to crash, they could be built lighter, reducing fuel consumption. But of course, to be truly safer, the cars must be far more reliable than, say, today's personal computers, which crash on occasion and are frequently infected.

Glenn Beck as America's Professor - 0 views

  • In terms of presidents, it’s like giving a lecture about James Bond focused entirely on George Lazenby.
  • Well, scholarship has a certain authority, and Beck would like to claim that authority. In the post-civil rights era, Beck's familiar us-versus-them stance can't be framed in terms of identity; most of his audience may be white and middle-class and older, but even older middle-class white people would be uncomfortable publicly making the argument that they deserve to be heard because they are older and middle-class and white. Instead, he (and many other media figures on both sides of the spectrum) utilize the stance that their audience deserves to be heard because they're objectively correct about certain things.
  • Beck is taking advantage of the American tradition of the “self-made man."
  • ...9 more annotations...
  • The problem with this sort of learning, though, is that there's no one to tell you if you're getting it wrong, no one to tell you about the recent Economist article nicely summarizes the problems with Beck's method: If you try to teach yourself history and political science from scratch, you're likely to draw a lot of shallow and inaccurate conclusions, particularly when you're the sort of person who's predisposed to seeing things in terms of white hats and black hats. One role of instructors, particularly at the college level, is to smack down the sweeping generalisations and facile analogies their students tend to make, and try to force them to adopt more rigorous and complicated approaches. But what if you're surrounded by people who reward you handsomely for making sweeping, slanderous generalisations, both because it delivers ratings and because it's ideologically helpful?
  • But when Beck argued on-air that Hoover's depression-causing mistake was backing away from Coolidge's laissez-faire policies (rather than, say, not allowing the government to pursue more activist strategies), he's doing so not on the basis of a careful assessment of the facts but because it fits in with his ideological assumptions: laissez-faire economic policies couldn't have caused the depression, because laissez-faire policies only cause good things.
  • This sort of reasoning is sufficient for politics, but in a more academic context it looks an awful lot like question-begging. Despite the props of learning he employs (blackboards, spectacles, pointers, Socratic dialogue), Beck's technique brings him closer to the conspiracy theorist than to the scholar.
  • by carefully hewing to the performance of the self-made scholar, Beck is able to make his audience feel like they're learning something new, even when they're just being told the same old thing.
  • The big question with Beck, as it is with a lot of figures in the latter-day conservative moment, is this: what is he? Is he evil? Ignorant? Performance art?
  • The conservative guy who comes to a school-board meeting demanding that they not teach evolution just wants everyone to agree with him. As do we all! In terms of motivation, liberals' demands that the unpleasant parts of American history be taught in schools is no different from conservatives' insistence that they be expunged: both want the story told as they see it so that children will grow up sympathetic to their view of the world. Of course, liberals have the advantage in this case of wanting things to be revealing, rather than concealing. But that doesn't make our intentions any nobler, particularly.
  • it would take a pretty stupid conservative not to question the fundamental aspects of their political beliefs after an arch-conservative, ultra-capitalist Republican president ushered in a massive recession.
  • But it's unrealistic to expect them to change their minds; after all, neither liberals nor conservatives change their political beliefs very often. Instead, we just find new ways to justify our ideology, which indicates, I suspect, that our political beliefs are more of a cultural trait than a carefully reasoned view.
  • Glenn Beck tells a good story; Glenn Beck makes, though he doesn't intend to, impressive art. The world would just be a better place, I tend to think, if he stuck to novels.
  •  
    "Recently I decided to check in with Glenn Beck. (I do this semi-regularly with all the various cable news talk shows out of a sense of responsibility, though I never last more than about 10 minutes at a stretch.) I was not optimistic. Based on the clips I'd been exposed to by people who don't like Glenn Beck, I expected a mix between a revival meeting, a Klan rally, and the McCarthy hearings. Instead, I got Glenn in front of a blackboard, lecturing about…Calvin Coolidge." By Mike Barthel at The Awl on October 11, 2010.

Beyond the 10,000 Hour Rule: Richard Hamming and the Messy Art of Becoming Great - 0 views

  • To me, the speech’s impact diluted among its many disconnected insights. I didn’t come away with a clear new model for how to structure my research career, so I ignored Hamming’s advice, responding politely, but somewhat dismissively, as readers continued to point me toward the talk as a potential source of wisdom. Now that I’m over a decade into my training as a professional scientist, however, I’m finally beginning to notice the elegance behind Hamming’s words. With this talk, I came to realize, he’s capturing a crucial truth: in many fields, including research science, the path to becoming excellent is messy and ambiguous.
  • This rule reduces achievement to quantity: the secret to becoming great is to do a great amount of work. What Hamming emphasizes, however, is that quantity alone is not sufficient. (“I’ve often wondered why so many of my good friends at Bell Labs who worked as hard or harder than I did, didn’t have so much to show for it,” he asks at one point in his speech.) Those 10,000 hours have to be invested in the right things, and as the disjointed nature of Hamming’s talk underscores, the question of what are the right things is slippery and near impossible to nail down with confidence.

  • “Great scientists tolerate ambiguity very well,” Hamming says. “They believe the theory enough to go ahead; [but] they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory.”

    "In March of 1986, an overflow audience of over 200 researchers and staff members from Bell Laboratories piled into the Morris Research and Engineering Center to hear a talk given by Dr. Richard Hamming, a pioneer in the field of communication theory. He titled his presentation "You and Your Research," and set out to answer a fundamental question: "Why do so few scientists make significant contributions and so many are forgotten in the long run?" Hamming, of course, knew what he was talking about, as he had made his own significant contributions - you can't even glance at the field of digital communications without stumbling over some eponymous Hamming innovation."

US scientists significantly more likely to publish fake research - 0 views

  • The study author searched the PubMed database for every scientific research paper that had been withdrawn—and therefore officially expunged from the public record—between 2000 and 2010.
  • "The duplicity of some authors is cause for concern," comments the author. Retraction is the strongest sanction that can be applied to published research, but currently, "[it] is a very blunt instrument used for offences both gravely serious and trivial."
  • And lets not let journals from other countries get off the hook, they publish fake stuff and duplicative research.  They just don't retract it.

Einstein's Arrogance - 0 views

  • To assign more than 50% probability to the correct candidate from a pool of 100,000,000 possible hypotheses, you need at least 27 bits of evidence (or thereabouts).
  • The Traditional phrasing implies that you start out with a hunch, or some private line of reasoning that leads you to a suggested hypothesis, and then you have to gather "evidence" to confirm it - to convince the scientific community, or justify saying that you believe in your hunch.
  • But from a Bayesian perspective, you need an amount of evidence roughly equivalent to the complexity of the hypothesis just to locate the hypothesis in theory-space.
  •  
    "In 1919, Sir Arthur Eddington led expeditions to Brazil and to the island of Principe, aiming to observe solar eclipses and thereby test an experimental prediction of Einstein's novel theory of General Relativity. A journalist asked Einstein what he would do if Eddington's observations failed to match his theory. Einstein famously replied: 'Then I would feel sorry for the good Lord. The theory is correct.'"

Rand and Empirical Responsibility 2 - 0 views

  • "The use or misuse of his cognitive faculty determines a man’s choice of values, which determine his emotions and his character. It is in this sense that man is a being of self-made soul."
  • To describe this viewpoint as controversial greatly understates its tremendous reach. Were it true, it would mean that nearly every scientist in the biological and behavorial sciences, nearly every great poet, dramatist, and novelist, and all great statemen, generals, businessmen, etc. have been wrong; for nearly everyone who has ever studied, described, bargained with, dealt with, or commanded human beings has assumed that man is not a being of self-made soul, that his "soul" (or character) is a product of many factors, and that something called "human nature" most definitely exists and can be used to make generalizations concerning how human beings are likely to react to various incentives.
  • Rand's assertion that man is a being of self-made soul goes into the very teeth of this evidence.

  • Rand cites no scientific experiment, no article from a reputable scientific journal, no evidence from experimental psychology.
  • It's one of their philosophy's chief presuppositions. Without it, the whole structure becomes wobbly, and threatens to fall.
  • Take away Rand's extreme self-determinism, and the old rules apply once again. The conservative (or "Tragic") vision of human nature, dramatized by Sophocles and Shakespeare, limned by James Madison and Alexander Hamilton in the Federalist Papers, scientifically explicated by E.O. Wilson, Steven Pinker, and other scientists, is once more vindicated.

    "Man is a being of self-made soul. Rand explains this assertion as follows: "The use or misuse of his cognitive faculty determines a man's choice of values, which determine his emotions and his character. It is in this sense that man is a being of self-made soul." In other words, a man's "character and emotions" are determined by how he uses (or misuses) his consciousness. Under this view, a man is responsible not merely for how he behaves, but for his personality and emotions." By Greg Nyquist at Ayn Rand Contra Human Nature
