Opinion | How Genetics Is Changing Our Understanding of 'Race' - The New York Times - 0 views

genetics race science research human origins

shared by Javier E on 25 Mar 18 - No Cached
  • In 1942, the anthropologist Ashley Montagu published “Man’s Most Dangerous Myth: The Fallacy of Race,” an influential book that argued that race is a social concept with no genetic basis.
  • eginning in 1972, genetic findings began to be incorporated into this argument. That year, the geneticist Richard Lewontin published an important study of variation in protein types in blood. He grouped the human populations he analyzed into seven “races” — West Eurasians, Africans, East Asians, South Asians, Native Americans, Oceanians and Australians — and found that around 85 percent of variation in the protein types could be accounted for by variation within populations and “races,” and only 15 percent by variation across them. To the extent that there was variation among humans, he concluded, most of it was because of “differences between individuals.”
  • In this way, a consensus was established that among human populations there are no differences large enough to support the concept of “biological race.” Instead, it was argued, race is a “social construct,” a way of categorizing people that changes over time and across countries.

  • t is true that race is a social construct. It is also true, as Dr. Lewontin wrote, that human populations “are remarkably similar to each other” from a genetic point of view.
  • this consensus has morphed, seemingly without questioning, into an orthodoxy. The orthodoxy maintains that the average genetic differences among people grouped according to today’s racial terms are so trivial when it comes to any meaningful biological traits that those differences can be ignored.
  • With the help of these tools, we are learning that while race may be a social construct, differences in genetic ancestry that happen to correlate to many of today’s racial constructs are real.
  • I have deep sympathy for the concern that genetic discoveries could be misused to justify racism. But as a geneticist I also know that it is simply no longer possible to ignore average genetic differences among “races.”
  • Groundbreaking advances in DNA sequencing technology have been made over the last two decades
  • Care.
  • The orthodoxy goes further, holding that we should be anxious about any research into genetic differences among populations
  • You will sometimes hear that any biological differences among populations are likely to be small, because humans have diverged too recently from common ancestors for substantial differences to have arisen under the pressure of natural selection. This is not true. The ancestors of East Asians, Europeans, West Africans and Australians were, until recently, almost completely isolated from one another for 40,000 years or longer, which is more than sufficient time for the forces of evolution to work
  • I am worried that well-meaning people who deny the possibility of substantial biological differences among human populations are digging themselves into an indefensible position, one that will not survive the onslaught of science.
  • I am also worried that whatever discoveries are made — and we truly have no idea yet what they will be — will be cited as “scientific proof” that racist prejudices and agendas have been correct all along, and that those well-meaning people will not understand the science well enough to push back against these claims.
  • This is why it is important, even urgent, that we develop a candid and scientifically up-to-date way of discussing any such difference
  • While most people will agree that finding a genetic explanation for an elevated rate of disease is important, they often draw the line there. Finding genetic influences on a propensity for disease is one thing, they argue, but looking for such influences on behavior and cognition is another
  • Is performance on an intelligence test or the number of years of school a person attends shaped by the way a person is brought up? Of course. But does it measure something having to do with some aspect of behavior or cognition? Almost certainly.
  • Recent genetic studies have demonstrated differences across populations not just in the genetic determinants of simple traits such as skin color, but also in more complex traits like bodily dimensions and susceptibility to diseases.
  • in Iceland, there has been measurable genetic selection against the genetic variations that predict more years of education in that population just within the last century.
  • consider what kinds of voices are filling the void that our silence is creating
  • Nicholas Wade, a longtime science journalist for The New York Times, rightly notes in his 2014 book, “A Troublesome Inheritance: Genes, Race and Human History,” that modern research is challenging our thinking about the nature of human population differences. But he goes on to make the unfounded and irresponsible claim that this research is suggesting that genetic factors explain traditional stereotypes.
  • 139 geneticists (including myself) pointed out in a letter to The New York Times about Mr. Wade’s book, there is no genetic evidence to back up any of the racist stereotypes he promotes.
  • Another high-profile example is James Watson, the scientist who in 1953 co-discovered the structure of DNA, and who was forced to retire as head of the Cold Spring Harbor Laboratories in 2007 after he stated in an interview — without any scientific evidence — that research has suggested that genetic factors contribute to lower intelligence in Africans than in Europeans.
  • What makes Dr. Watson’s and Mr. Wade’s statements so insidious is that they start with the accurate observation that many academics are implausibly denying the possibility of average genetic differences among human populations, and then end with a claim — backed by no evidence — that they know what those differences are and that they correspond to racist stereotypes
  • They use the reluctance of the academic community to openly discuss these fraught issues to provide rhetorical cover for hateful ideas and old racist canards.
  • This is why knowledgeable scientists must speak out. If we abstain from laying out a rational framework for discussing differences among populations, we risk losing the trust of the public and we actively contribute to the distrust of expertise that is now so prevalent.
  • If scientists can be confident of anything, it is that whatever we currently believe about the genetic nature of differences among populations is most likely wrong.
  • For example, my laboratory discovered in 2016, based on our sequencing of ancient human genomes, that “whites” are not derived from a population that existed from time immemorial, as some people believe. Instead, “whites” represent a mixture of four ancient populations that lived 10,000 years ago and were each as different from one another as Europeans and East Asians are today.
  • For me, a natural response to the challenge is to learn from the example of the biological differences that exist between males and females
  • The differences between the sexes are far more profound than those that exist among human populations, reflecting more than 100 million years of evolution and adaptation. Males and females differ by huge tracts of genetic material
  • How do we accommodate the biological differences between men and women? I think the answer is obvious: We should both recognize that genetic differences between males and females exist and we should accord each sex the same freedoms and opportunities regardless of those differences
  • fulfilling these aspirations in practice is a challenge. Yet conceptually it is straightforward.
  • Compared with the enormous differences that exist among individuals, differences among populations are on average many times smaller, so it should be only a modest challenge to accommodate a reality in which the average genetic contributions to human traits differ.

  • No one was more influential — or more terrifying, some would say — than Paul R. Ehrlich, a Stanford University biologist. His 1968 book, “The Population Bomb,” sold in the millions with a jeremiad that humankind stood on the brink of apocalypse because there were simply too many of us. Dr. Ehrlich’s opening statement was the verbal equivalent of a punch to the gut: “The battle to feed all of humanity is over.” He later went on to forecast that hundreds of millions would starve to death in the 1970s, that 65 million of them would be Americans, that crowded India was essentially doomed, that odds were fair “England will not exist in the year 2000.” Dr. Ehrlich was so sure of himself that he warned in 1970 that “sometime in the next 15 years, the end will come.” By “the end,” he meant “an utter breakdown of the capacity of the planet to support humanity.”
  • After the passage of 47 years, Dr. Ehrlich offers little in the way of a mea culpa. Quite the contrary. Timetables for disaster like those he once offered have no significance, he told Retro Report, because to someone in his field they mean something “very, very different” from what they do to the average person. The end is still nigh, he asserted, and he stood unflinchingly by his 1960s insistence that population control was required, preferably through voluntary methods. But if need be, he said, he would endorse “various forms of coercion” like eliminating “tax benefits for having additional children.”
  • Stewart Brand, founding editor of the Whole Earth Catalog. On this topic, Mr. Brand may be deemed a Keynesian, in the sense of an observation often attributed to John Maynard Keynes: “When the facts change, I change my mind, sir. What do you do?” Mr. Brand’s formulation for Retro Report was to ask, “How many years do you have to not have the world end” to reach a conclusion that “maybe it didn’t end because that reason was wrong?”

  • One thing that happened on the road to doom was that the world figured out how to feed itself despite its rising numbers. No small measure of thanks belonged to Norman E. Borlaug, an American plant scientist whose breeding of high-yielding, disease-resistant crops led to the agricultural savior known as the Green Revolution.
  • Some preternaturally optimistic analysts concluded that humans would always find their way out of tough spots. Among them was Julian L. Simon, an economist who established himself as the anti-Ehrlich, arguing that “humanity’s condition will improve in just about every material way.”
  • In fact, birthrates are now below long-term replacement levels, or nearly so, across much of Earth, not just in the industrialized West and Japan but also in India, China, much of Southeast Asia, Latin America — just about everywhere except Africa, although even there the continentwide rates are declining. “Girls that are never born cannot have babies,”
  • Because of improved health standards, birthing many children is not the survival imperative for families that it once was. In cramped cities, large families are not the blessing they were in the agricultural past. And women in many societies are ever more independent, socially and economically; they no longer accept that their fate is to be endlessly pregnant. If anything, the worry in many countries is that their populations are aging and that national vitality is ebbing.
  • Still, enough people are already around to ensure that the world’s population will keep rising. But for how long? That is a devilishly difficult question. One frequently cited demographic model by the United Nations envisions a peak of about nine billion around 2050. Other forecasts are for continued growth into the next century. Still others say the population will begin to drop before the middle of this century.
  • In Mr. Pearce’s view, the villain is not overpopulation but, rather, overconsumption. “We can survive massive demographic change,” he said in 2011. But he is less sanguine about the overuse of available resources and its effects on climate change
  • “Rising consumption today far outstrips the rising head count as a threat to the planet,” Mr. Pearce wrote in Prospect, a British magazine, in 2010. “And most of the extra consumption has been in rich countries that have long since given up adding substantial numbers to their population,
  • “Let’s look at carbon dioxide emissions, the biggest current concern because of climate change,” he continued. “The world’s richest half billion people — that’s about 7 percent of the global population — are responsible for half of the world’s carbon dioxide emissions. Meanwhile, the poorest 50 percent of the population are responsible for just 7 percent of emissions.”

Reasons for COVID-19 Optimism on T-Cells and Herd Immunity - 0 views

immunity Covid-19 research science

  • It may well be the case that some amount of community protection kicks in below 60 percent exposure, and possibly quite a bit below that threshold, and that those who exhibit a cross-reactive T-cell immune response, while still susceptible to infection, may also have some meaningful amount of protection against severe disease.
  • early returns suggest that while the maximalist interpretation of each hypothesis is not very credible — herd immunity has probably not been reached in many places, and cross-reactive T-cell response almost certainly does not functionally immunize those who have it — more modest interpretations appear quite plausible.
  • Friston suggested that the truly susceptible portion of the population was certainly not 100 percent, as most modelers and conventional wisdom had it, but a much smaller share — surely below 50 percent, he said, and likely closer to about 20 percent. The analysis was ongoing, he said, but, “I suspect, once this has been done, it will look like the effective non-susceptible portion of the population will be about 80 percent. I think that’s what’s going to happen.”

  • one of the leading modelers, Gabriela Gomes, suggested the entire area of research was being effectively blackballed out of fear it might encourage a relaxation of pandemic vigilance. “This is the very sad reason for the absence of more optimistic projections on the development of this pandemic in the scientific literature,” she wrote on Twitter. “Our analysis suggests that herd-immunity thresholds are being achieved despite strict social-distancing measures.”
  • Gomes suggested, herd immunity could happen with as little as one quarter of the population of a community exposed — or perhaps just 20 percent. “We just keep running the models, and it keeps coming back at less than 20 percent,” she told Hamblin. “It’s very striking.” Such findings, if they held up, would be very instructive, as Hamblin writes: “It would mean, for instance, that at 25 percent antibody prevalence, New York City could continue its careful reopening without fear of another major surge in cases.”
  • But for those hoping that 25 percent represents a true ceiling for pandemic spread in a given community, well, it almost certainly does not, considering that recent serological surveys have shown that perhaps 93 percent of the population of Iquitos, Peru, has contracted the disease; as have more than half of those living in Indian slums; and as many as 68 percent in particular neighborhoods of New York City
  • overshoot of that scale would seem unlikely if the “true” threshold were as low as 20 or 25 percent.
  • But, of course, that threshold may not be the same in all places, across all populations, and is surely affected, to some degree, by the social behavior taken to protect against the spread of the disease.
  • we probably err when we conceive of group immunity in simplistically binary terms. While herd immunity is a technical term referring to a particular threshold at which point the disease can no longer spread, some amount of community protection against that spread begins almost as soon as the first people are exposed, with each case reducing the number of unexposed and vulnerable potential cases in the community by one
  • you would not expect a disease to spread in a purely exponential way until the point of herd immunity, at which time the spread would suddenly stop. Instead, you would expect that growth to slow as more people in the community were exposed to the disease, with most of them emerging relatively quickly with some immune response. Add to that the effects of even modest, commonplace protections — intuitive social distancing, some amount of mask-wearing — and you could expect to get an infection curve that tapers off well shy of 60 percent exposure.
  • Looking at the data, we see that transmissions in many severely impacted states began to slow down in July, despite limited interventions. This is especially notable in states like Arizona, Florida, and Texas. While we believe that changes in human behavior and changes in policy (such as mask mandates and closing of bars/nightclubs) certainly contributed to the decrease in transmission, it seems unlikely that these were the primary drivers behind the decrease. We believe that many regions obtained a certain degree of temporary herd immunity after reaching 10-35 percent prevalence under the current conditions. We call this 10-35 percent threshold the effective herd immunity threshold.
  • Indeed, that is more or less what was recently found by Youyang Gu, to date the best modeler of pandemic spread in the U.S
  • he cautioned again that he did not mean to imply that the natural herd-immunity level was as low as 10 percent, or even 35 percent. Instead, he suggested it was a plateau determined in part by better collective understanding of the disease and what precautions to take
  • Gu estimates national prevalence as just below 20 percent (i.e., right in the middle of his range of effective herd immunity), it still counts, I think, as encouraging — even if people in hard-hit communities won’t truly breathe a sigh of relief until vaccines arrive.
  • If you can get real protection starting at 35 percent, it means that even a mediocre vaccine, administered much more haphazardly to a population with some meaningful share of vaccination skeptics, could still achieve community protection pretty quickly. And that is really significant — making both the total lack of national coordination on rollout and the likely “vaccine wars” much less consequential.
  • At least 20 percent of the public, and perhaps 50 percent, had some preexisting, cross-protective T-cell response to SARS-CoV-2, according to one much-discussed recent paper. An earlier paper had put the figure at between 40 and 60 percent. And a third had found an even higher prevalence: 81 percent.
  • The T-cell story is similarly encouraging in its big-picture implications without being necessarily paradigm-changing
  • These numbers suggest their own heterogeneity — that different populations, with different demographics, would likely exhibit different levels of cross-reactive T-cell immune response
  • The most optimistic interpretation of the data was given to me by Francois Balloux, a somewhat contrarian disease geneticist and the director of the University College of London’s Genetics Institute
  • According to him, a cross-reactive T-cell response wouldn’t prevent infection, but would probably mean a faster immune response, a shorter period of infection, and a “massively” reduced risk of severe illness — meaning, he guessed, that somewhere between a third and three-quarters of the population carried into the epidemic significant protection against its scariest outcomes
  • the distribution of this T-cell response could explain at least some, and perhaps quite a lot, of COVID-19’s age skew when it comes to disease severity and mortality, since the young are the most exposed to other coronaviruses, and the protection tapers as you get older and spend less time in environments, like schools, where these viruses spread so promiscuously.
  • Balloux told me he believed it was also possible that the heterogeneous distribution of T-cell protection also explains some amount of the apparent decline in disease severity over time within countries on different pandemic timelines — a phenomenon that is more conventionally attributed to infection spreading more among the young, better treatment, and more effective protection of the most vulnerable (especially the old).
  • Going back to Youyang Gu’s analysis, what he calls the “implied infection fatality rate” — essentially an estimated ratio based on his modeling of untested cases — has fallen for the country as a whole from about one percent in March to about 0.8 percent in mid-April, 0.6 percent in May, and down to about 0.25 percent today.
  • even as we have seemed to reach a second peak of coronavirus deaths, the rate of death from COVID-19 infection has continued to decline — total deaths have gone up, but much less than the number of cases
  • In other words, at the population level, the lethality of the disease in America has fallen by about three-quarters since its peak. This is, despite everything that is genuinely horrible about the pandemic and the American response to it, rather fantastic.
  • there may be some possible “mortality displacement,” whereby the most severe cases show up first, in the most susceptible people, leaving behind a relatively protected population whose experience overall would be more mild, and that T-cell response may play a significant role in determining that susceptibility.
  • That, again, is Balloux’s interpretation — the most expansive assessment of the T-cell data offered to me
  • The most conservative assessment came from Sarah Fortune, the chair of Harvard’s Department of Immunology
  • Fortune cautioned not to assume that cross-protection was playing a significant role in determining severity of illness in a given patient. Those with such a T-cell response, she told me, would likely see a faster onset of robust response, yes, but that may or may not yield a shorter period of infection and viral shedding
  • Most of the scientists, doctors, epidemiologists, and immunologists I spoke to fell between those two poles, suggesting the T-cell cross-immunity findings were significant without necessarily being determinative — that they may help explain some of the shape of pandemic spread through particular populations, but only some of the dynamics of that spread.
  • he told me he believed, in the absence of that data, that T-cell cross-immunity from exposure to previous coronaviruses “might explain different disease severity in different people,” and “could certainly be part of the explanation for the age skew, especially for why the very young fare so well.”
  • the headline finding was quite clear and explicitly stated: that preexisting T-cell response came primarily via the variety of T-cells called CD4 T-cells, and that this dynamic was consistent with the hypothesis that the mechanism was inherited from previous exposure to a few different “common cold” coronaviruses
  • “This potential preexisting cross-reactive T-cell immunity to SARS-CoV-2 has broad implications,” the authors wrote, “as it could explain aspects of differential COVID-19 clinical outcomes, influence epidemiological models of herd immunity, or affect the performance of COVID-19 candidate vaccines.”
  • “This is at present highly speculative,” they cautioned.

    Although the society now is closely intertwined with science, real and up-to-date science is still very far away from the general population. As we discussed in TOK when we talked about science, the science that the general population talk about and quote from is mostly not real or scientific science. They don't really care the scientific methods and all those theories behind those conclusions. They just use those "science facts" to satisfy their confirmation bias and support their argument. From this research, we can just see how the general population don't really care about real science. Science is becoming more like a special thing that is only in the hands of the minority elites. Although they say that general population is not important for science, I think it is really important that the science that the general population perceive is real science. --Sissi (4/21/2017)

  • “Chicago is the only global city in America whose population is declining, and do you know why? Because African American families are leaving this city by the thousands,” said Chicago planning department chief Maurice Cox at the recent kickoff event in Austin for the INVEST South/West initiative. “This is a troubling trend.”

  • Social scientists have identified at least three major forces that collectively bind together successful democracies: social capital (extensive social networks with high levels of trust), strong institutions, and shared stories.
  • Social media has weakened all three.
  • gradually, social-media users became more comfortable sharing intimate details of their lives with strangers and corporations.

  • That began to change in 2009, when Facebook offered users a way to publicly “like” posts with the click of a button. That same year, Twitter introduced something even more powerful: the “Retweet” button, which allowed users to publicly endorse a post while also sharing it with all of their followers.

  • Facebook developed algorithms to bring each user the content most likely to generate a “like” or some other interaction, eventually including the “share” as well.

  • By 2013, social media had become a new game, with dynamics unlike those in 2008. If you were skillful or lucky, you might create a post that would “go viral” and make you “internet famous”

  • As a social psychologist who studies emotion, morality, and politics, I saw this happening too. The newly tweaked platforms were almost perfectly designed to bring out our most moralistic and least reflective selves. The volume of outrage was shocking.
  • It was just this kind of twitchy and explosive spread of anger that James Madison had tried to protect us from as he was drafting the U.S. Constitution.
  • The Framers of the Constitution were excellent social psychologists. They knew that democracy had an Achilles’ heel because it depended on the collective judgment of the people, and democratic communities are subject to “the turbulency and weakness of unruly passions.”
  • The key to designing a sustainable republic, therefore, was to build in mechanisms to slow things down, cool passions, require compromise, and give leaders some insulation from the mania of the moment while still holding them accountable to the people periodically, on Election Day.
  • The tech companies that enhanced virality from 2009 to 2012 brought us deep into Madison’s nightmare.
  • a less quoted yet equally important insight, about democracy’s vulnerability to triviality.
  • Madison notes that people are so prone to factionalism that “where no substantial occasion presents itself, the most frivolous and fanciful distinctions have been sufficient to kindle their unfriendly passions and excite their most violent conflicts.”
  • Social media has both magnified and weaponized the frivolous.
  • It’s not just the waste of time and scarce attention that matters; it’s the continual chipping-away of trust.
  • a democracy depends on widely internalized acceptance of the legitimacy of rules, norms, and institutions.
  • when citizens lose trust in elected leaders, health authorities, the courts, the police, universities, and the integrity of elections, then every decision becomes contested; every election becomes a life-and-death struggle to save the country from the other side
  • The most recent Edelman Trust Barometer (an international measure of citizens’ trust in government, business, media, and nongovernmental organizations) showed stable and competent autocracies (China and the United Arab Emirates) at the top of the list, while contentious democracies such as the United States, the United Kingdom, Spain, and South Korea scored near the bottom (albeit above Russia).
  • The literature is complex—some studies show benefits, particularly in less developed democracies—but the review found that, on balance, social media amplifies political polarization; foments populism, especially right-wing populism; and is associated with the spread of misinformation.
  • When people lose trust in institutions, they lose trust in the stories told by those institutions. That’s particularly true of the institutions entrusted with the education of children.
  • Facebook and Twitter make it possible for parents to become outraged every day over a new snippet from their children’s history lessons––and math lessons and literature selections, and any new pedagogical shifts anywhere in the country
  • The motives of teachers and administrators come into question, and overreaching laws or curricular reforms sometimes follow, dumbing down education and reducing trust in it further.
  • young people educated in the post-Babel era are less likely to arrive at a coherent story of who we are as a people, and less likely to share any such story with those who attended different schools or who were educated in a different decade.
  • former CIA analyst Martin Gurri predicted these fracturing effects in his 2014 book, The Revolt of the Public. Gurri’s analysis focused on the authority-subverting effects of information’s exponential growth, beginning with the internet in the 1990s. Writing nearly a decade ago, Gurri could already see the power of social media as a universal solvent, breaking down bonds and weakening institutions everywhere it reached.
  • he notes a constructive feature of the pre-digital era: a single “mass audience,” all consuming the same content, as if they were all looking into the same gigantic mirror at the reflection of their own society. I
  • The digital revolution has shattered that mirror, and now the public inhabits those broken pieces of glass. So the public isn’t one thing; it’s highly fragmented, and it’s basically mutually hostile
  • Facebook, Twitter, YouTube, and a few other large platforms unwittingly dissolved the mortar of trust, belief in institutions, and shared stories that had held a large and diverse secular democracy together.
  • I think we can date the fall of the tower to the years between 2011 (Gurri’s focal year of “nihilistic” protests) and 2015, a year marked by the “great awokening” on the left and the ascendancy of Donald Trump on the right.
  • Twitter can overpower all the newspapers in the country, and stories cannot be shared (or at least trusted) across more than a few adjacent fragments—so truth cannot achieve widespread adherence.
  • fter Babel, nothing really means anything anymore––at least not in a way that is durable and on which people widely agree.
  • Politics After Babel
  • “Politics is the art of the possible,” the German statesman Otto von Bismarck said in 1867. In a post-Babel democracy, not much may be possible.
  • The ideological distance between the two parties began increasing faster in the 1990s. Fox News and the 1994 “Republican Revolution” converted the GOP into a more combative party.
  • So cross-party relationships were already strained before 2009. But the enhanced virality of social media thereafter made it more hazardous to be seen fraternizing with the enemy or even failing to attack the enemy with sufficient vigor.
  • What changed in the 2010s? Let’s revisit that Twitter engineer’s metaphor of handing a loaded gun to a 4-year-old. A mean tweet doesn’t kill anyone; it is an attempt to shame or punish someone publicly while broadcasting one’s own virtue, brilliance, or tribal loyalties. It’s more a dart than a bullet
  • from 2009 to 2012, Facebook and Twitter passed out roughly 1 billion dart guns globally. We’ve been shooting one another ever since.
  • “devoted conservatives,” comprised 6 percent of the U.S. population.
  • the warped “accountability” of social media has also brought injustice—and political dysfunction—in three ways.
  • First, the dart guns of social media give more power to trolls and provocateurs while silencing good citizens.
  • a small subset of people on social-media platforms are highly concerned with gaining status and are willing to use aggression to do so.
  • Across eight studies, Bor and Petersen found that being online did not make most people more aggressive or hostile; rather, it allowed a small number of aggressive people to attack a much larger set of victims. Even a small number of jerks were able to dominate discussion forums,
  • Additional research finds that women and Black people are harassed disproportionately, so the digital public square is less welcoming to their voices.
  • Second, the dart guns of social media give more power and voice to the political extremes while reducing the power and voice of the moderate majority.
  • The “Hidden Tribes” study, by the pro-democracy group More in Common, surveyed 8,000 Americans in 2017 and 2018 and identified seven groups that shared beliefs and behaviors.
  • Social media has given voice to some people who had little previously, and it has made it easier to hold powerful people accountable for their misdeeds
  • The group furthest to the left, the “progressive activists,” comprised 8 percent of the population. The progressive activists were by far the most prolific group on social media: 70 percent had shared political content over the previous year. The devoted conservatives followed, at 56 percent.
  • These two extreme groups are similar in surprising ways. They are the whitest and richest of the seven groups, which suggests that America is being torn apart by a battle between two subsets of the elite who are not representative of the broader society.
  • they are the two groups that show the greatest homogeneity in their moral and political attitudes.
  • likely a result of thought-policing on social media:
  • political extremists don’t just shoot darts at their enemies; they spend a lot of their ammunition targeting dissenters or nuanced thinkers on their own team.
  • Finally, by giving everyone a dart gun, social media deputizes everyone to administer justice with no due process. Platforms like Twitter devolve into the Wild West, with no accountability for vigilantes.
  • Enhanced-virality platforms thereby facilitate massive collective punishment for small or imagined offenses, with real-world consequences, including innocent people losing their jobs and being shamed into suicide
  • we don’t get justice and inclusion; we get a society that ignores context, proportionality, mercy, and truth.
  • Since the tower fell, debates of all kinds have grown more and more confused. The most pervasive obstacle to good thinking is confirmation bias, which refers to the human tendency to search only for evidence that confirms our preferred beliefs
  • search engines were supercharging confirmation bias, making it far easier for people to find evidence for absurd beliefs and conspiracy theorie
  • The most reliable cure for confirmation bias is interaction with people who don’t share your beliefs. They confront you with counterevidence and counterargument.
  • In his book The Constitution of Knowledge, Jonathan Rauch describes the historical breakthrough in which Western societies developed an “epistemic operating system”—that is, a set of institutions for generating knowledge from the interactions of biased and cognitively flawed individuals
  • English law developed the adversarial system so that biased advocates could present both sides of a case to an impartial jury.
  • Newspapers full of lies evolved into professional journalistic enterprises, with norms that required seeking out multiple sides of a story, followed by editorial review, followed by fact-checking.
  • Universities evolved from cloistered medieval institutions into research powerhouses, creating a structure in which scholars put forth evidence-backed claims with the knowledge that other scholars around the world would be motivated to gain prestige by finding contrary evidence.
  • Part of America’s greatness in the 20th century came from having developed the most capable, vibrant, and productive network of knowledge-producing institutions in all of human history
  • But this arrangement, Rauch notes, “is not self-maintaining; it relies on an array of sometimes delicate social settings and understandings, and those need to be understood, affirmed, and protected.”
  • This, I believe, is what happened to many of America’s key institutions in the mid-to-late 2010s. They got stupider en masse because social media instilled in their members a chronic fear of getting darted
  • it was so pervasive that it established new behavioral norms backed by new policies seemingly overnight
  • Participants in our key institutions began self-censoring to an unhealthy degree, holding back critiques of policies and ideas—even those presented in class by their students—that they believed to be ill-supported or wrong.
  • The stupefying process plays out differently on the right and the left because their activist wings subscribe to different narratives with different sacred values.
  • The “Hidden Tribes” study tells us that the “devoted conservatives” score highest on beliefs related to authoritarianism. They share a narrative in which America is eternally under threat from enemies outside and subversives within; they see life as a battle between patriots and traitors.
  • they are psychologically different from the larger group of “traditional conservatives” (19 percent of the population), who emphasize order, decorum, and slow rather than radical change.
  • The traditional punishment for treason is death, hence the battle cry on January 6: “Hang Mike Pence.”
  • Right-wing death threats, many delivered by anonymous accounts, are proving effective in cowing traditional conservatives
  • The wave of threats delivered to dissenting Republican members of Congress has similarly pushed many of the remaining moderates to quit or go silent, giving us a party ever more divorced from the conservative tradition, constitutional responsibility, and reality.
  • The stupidity on the right is most visible in the many conspiracy theories spreading across right-wing media and now into Congress.
  • The Democrats have also been hit hard by structural stupidity, though in a different way. In the Democratic Party, the struggle between the progressive wing and the more moderate factions is open and ongoing, and often the moderates win.
  • The problem is that the left controls the commanding heights of the culture: universities, news organizations, Hollywood, art museums, advertising, much of Silicon Valley, and the teachers’ unions and teaching colleges that shape K–12 education. And in many of those institutions, dissent has been stifled:
  • Liberals in the late 20th century shared a belief that the sociologist Christian Smith called the “liberal progress” narrative, in which America used to be horrifically unjust and repressive, but, thanks to the struggles of activists and heroes, has made (and continues to make) progress toward realizing the noble promise of its founding.
  • It is also the view of the “traditional liberals” in the “Hidden Tribes” study (11 percent of the population), who have strong humanitarian values, are older than average, and are largely the people leading America’s cultural and intellectual institutions.
  • when the newly viralized social-media platforms gave everyone a dart gun, it was younger progressive activists who did the most shooting, and they aimed a disproportionate number of their darts at these older liberal leaders.
  • Confused and fearful, the leaders rarely challenged the activists or their nonliberal narrative in which life at every institution is an eternal battle among identity groups over a zero-sum pie, and the people on top got there by oppressing the people on the bottom. This new narrative is rigidly egalitarian––focused on equality of outcomes, not of rights or opportunities. It is unconcerned with individual rights.
  • The universal charge against people who disagree with this narrative is not “traitor”; it is “racist,” “transphobe,” “Karen,” or some related scarlet letter marking the perpetrator as one who hates or harms a marginalized group.
  • The punishment that feels right for such crimes is not execution; it is public shaming and social death.
  • anyone on Twitter had already seen dozens of examples teaching the basic lesson: Don’t question your own side’s beliefs, policies, or actions. And when traditional liberals go silent, as so many did in the summer of 2020, the progressive activists’ more radical narrative takes over as the governing narrative of an organization.
  • This is why so many epistemic institutions seemed to “go woke” in rapid succession that year and the next, beginning with a wave of controversies and resignations at The New York Times and other newspapers, and continuing on to social-justice pronouncements by groups of doctors and medical associations
  • The problem is structural. Thanks to enhanced-virality social media, dissent is punished within many of our institutions, which means that bad ideas get elevated into official policy.
  • In a 2018 interview, Steve Bannon, the former adviser to Donald Trump, said that the way to deal with the media is “to flood the zone with shit.” He was describing the “firehose of falsehood” tactic pioneered by Russian disinformation programs to keep Americans confused, disoriented, and angry.
  • artificial intelligence is close to enabling the limitless spread of highly believable disinformation. The AI program GPT-3 is already so good that you can give it a topic and a tone and it will spit out as many essays as you like, typically with perfect grammar and a surprising level of coherence.
  • Renée DiResta, the research manager at the Stanford Internet Observatory, explained that spreading falsehoods—whether through text, images, or deep-fake videos—will quickly become inconceivably easy. (She co-wrote the essay with GPT-3.)
  • American factions won’t be the only ones using AI and social media to generate attack content; our adversaries will too.
  • In the 20th century, America’s shared identity as the country leading the fight to make the world safe for democracy was a strong force that helped keep the culture and the polity together.
  • In the 21st century, America’s tech companies have rewired the world and created products that now appear to be corrosive to democracy, obstacles to shared understanding, and destroyers of the modern tower.
  • What changes are needed?
  • I can suggest three categories of reforms––three goals that must be achieved if democracy is to remain viable in the post-Babel era.
  • We must harden democratic institutions so that they can withstand chronic anger and mistrust, reform social media so that it becomes less socially corrosive, and better prepare the next generation for democratic citizenship in this new age.
  • Harden Democratic Institutions
  • we must reform key institutions so that they can continue to function even if levels of anger, misinformation, and violence increase far above those we have today.
  • Reforms should reduce the outsize influence of angry extremists and make legislators more responsive to the average voter in their district.
  • One example of such a reform is to end closed party primaries, replacing them with a single, nonpartisan, open primary from which the top several candidates advance to a general election that also uses ranked-choice voting
  • A second way to harden democratic institutions is to reduce the power of either political party to game the system in its favor, for example by drawing its preferred electoral districts or selecting the officials who will supervise elections
  • These jobs should all be done in a nonpartisan way.
  • Reform Social Media
  • Social media’s empowerment of the far left, the far right, domestic trolls, and foreign agents is creating a system that looks less like democracy and more like rule by the most aggressive.
  • it is within our power to reduce social media’s ability to dissolve trust and foment structural stupidity. Reforms should limit the platforms’ amplification of the aggressive fringes while giving more voice to what More in Common calls “the exhausted majority.”
  • the main problem with social media is not that some people post fake or toxic stuff; it’s that fake and outrage-inducing content can now attain a level of reach and influence that was not possible before
  • Perhaps the biggest single change that would reduce the toxicity of existing platforms would be user verification as a precondition for gaining the algorithmic amplification that social media offers.
  • One of the first orders of business should be compelling the platforms to share their data and their algorithms with academic researchers.
  • Prepare the Next Generation
  • Childhood has become more tightly circumscribed in recent generations––with less opportunity for free, unstructured play; less unsupervised time outside; more time online. Whatever else the effects of these shifts, they have likely impeded the development of abilities needed for effective self-governance for many young adults
  • Depression makes people less likely to want to engage with new people, ideas, and experiences. Anxiety makes new things seem more threatening. As these conditions have risen and as the lessons on nuanced social behavior learned through free play have been delayed, tolerance for diverse viewpoints and the ability to work out disputes have diminished among many young people
  • Students did not just say that they disagreed with visiting speakers; some said that those lectures would be dangerous, emotionally devastating, a form of violence. Because rates of teen depression and anxiety have continued to rise into the 2020s, we should expect these views to continue in the generations to follow, and indeed to become more severe.
  • The most important change we can make to reduce the damaging effects of social media on children is to delay entry until they have passed through puberty.
  • The age should be raised to at least 16, and companies should be held responsible for enforcing it.
  • et them out to play. Stop starving children of the experiences they most need to become good citizens: free play in mixed-age groups of children with minimal adult supervision
  • while social media has eroded the art of association throughout society, it may be leaving its deepest and most enduring marks on adolescents. A surge in rates of anxiety, depression, and self-harm among American teens began suddenly in the early 2010s. (The same thing happened to Canadian and British teens, at the same time.) The cause is not known, but the timing points to social media as a substantial contributor—the surge began just as the large majority of American teens became daily users of the major platforms.
  • What would it be like to live in Babel in the days after its destruction? We know. It is a time of confusion and loss. But it is also a time to reflect, listen, and build.
  • In recent years, Americans have started hundreds of groups and organizations dedicated to building trust and friendship across the political divide, including BridgeUSA, Braver Angels (on whose board I serve), and many others listed at BridgeAlliance.us. We cannot expect Congress and the tech companies to save us. We must change ourselves and our communities.
  • when we look away from our dysfunctional federal government, disconnect from social media, and talk with our neighbors directly, things seem more hopeful. Most Americans in the More in Common report are members of the “exhausted majority,” which is tired of the fighting and is willing to listen to the other side and compromise. Most Americans now see that social media is having a negative impact on the country, and are becoming more aware of its damaging effects on children.

  • As human populations disperse, the separation leads to changes both in genes and in language. So if we look at human DNA and languages over time, we should find that they differ along similar geographic lines.
  • researchers decided to match large collections of geographic, linguistic, and genetic data on hundreds of human populations worldwide.
  • A new study, published in Proceedings of the National Academy of Sciences, quantifies the complicated relationship between these three factors. Researchers compared the geographic presence of two things in human populations across the world: alleles (trait-defining stretches of DNA) and phonemes (the distinct units of sound that make up spoken language).
  • ...3 more annotations...
  • in most parts of the world, languages and genes occupy the same areas and even appear to have traveled along similar trajectories.
  • These data have been available for some time, but never examined in the same place. “The thing we’ve done that no one else has is match worldwide genetic populations to their languages, so that you’re looking at a comparable set,”
  • Another finding is related to isolation: When small populations separate from the gene pool, genetic diversity falls. In language, the opposite is true. The study shows that isolation leads to more diversity in phonemes.

  • With 1.37 billion citizens, China has the world's largest population, but has one of the smallest surname pools. Only about 6,000 surnames are in use, according to the Ministry of Public Security. And the vast majority of the population -- almost 86% -- share just 100 of those surnames.
  • To put that in perspective, the United States -- with less than a quarter of China's population -- reported 6.3 million surnames in its 2010 census

  • people with rare characters in their names, which aren't compatible with existing computer systems, can get left behind -- pushing many to change their names for the sake of convenience, even if it means abandoning centuries of heritage and language.
  • China's history, full of migration, political turmoil and warfare, meant people's names were often in flux -- which is partly why many have since vanished.
  • People sometimes changed their names for convenience, too -- for instance, simplifying complex characters by adopting similar-sounding ones with fewer strokes. Other times they did it out of superstition, abandoning a name believed to bring ill fortune, said Chen, the associate professor.
  • surnames are lost or die out over time with each new generation as women take on their husbands' surnames.
  • With China roaring into the digital age, nearly everything -- from making appointments to buying train tickets -- has moved online. That meant a world of trouble if you happened to have a rare character in your name, that might not be in the database.
  • China's digitized ID cards made the problem even more pressing. The first generation of these cards allowed people to hand-write their names on -- but the second-generation cards, launched in 2004 and dubbed "smart cards" for their digital features, exclusively used computer-printed text.

  • This struggle, and the cost of adapting to the modern age, was exemplified in a village in the eastern Shandong province in the late 2000s. Many villagers shared the ancestral name "Shan" -- but when they began applying for the digitized ID cards, local officials advised them to change their surnames to "Xian," a similar-sounding but more common character, according to state-owned news service CNTV.

    With the development of Internet and social media, we find the news on the website, paper, TV more unreliable. Partly because we can easily find alternate statement that points out the flaws, but mostly, it's because the news today likes to use exaggeration to grab the attention of the general population. Media should realize the impact and panic it can cause in the society before they report news. Although freedom of speech is appreciated, that doesn't mean the media can put aside its responsibility to guide the general population in a good direction. I remember there was a fake news after the big earthquake in Japan saying that salt can prevent nuclear radiation, then people were all panic and bought salt. It was very funny that in some places, some people were even fighting for a pack of salt. The media should make sure that people won't misunderstand the message before they publish. --Sissi (2/1/2017)

collapse civilization decline history crisis politics economics culture complexity

shared by Javier E on 21 Dec 20 - No Cached
  • Tainter seemed calm. He walked me through the arguments of the book that made his reputation, “The Collapse of Complex Societies,” which has for years been the seminal text in the study of societal collapse, an academic subdiscipline that arguably was born with its publication in 1988
  • It is only a mild overstatement to suggest that before Tainter, collapse was simply not a thing.
  • His own research has moved on; these days, he focuses on “sustainability.”
  • ...53 more annotations...
  • He writes with disarming composure about the factors that have led to the disintegration of empires and the abandonment of cities and about the mechanism that, in his view, makes it nearly certain that all states that rise will one day fall
  • societal collapse and its associated terms — “fragility” and “resilience,” “risk” and “sustainability” — have become the objects of extensive scholarly inquiry and infrastructure.
  • Princeton has a research program in Global Systemic Risk, Cambridge a Center for the Study of Existential Risk
  • even Tainter, for all his caution and reserve, was willing to allow that contemporary society has built-in vulnerabilities that could allow things to go very badly indeed — probably not right now, maybe not for a few decades still, but possibly sooner. In fact, he worried, it could begin before the year was over.
  • Plato, in “The Republic,” compared cities to animals and plants, subject to growth and senescence like any living thing. The metaphor would hold: In the early 20th century, the German historian Oswald Spengler proposed that all cultures have souls, vital essences that begin falling into decay the moment they adopt the trappings of civilization.
  • that theory, which became the heart of “The Collapse of Complex Societies.” Tainter’s argument rests on two proposals. The first is that human societies develop complexity, i.e. specialized roles and the institutional structures that coordinate them, in order to solve problems
  • All history since then has been “characterized by a seemingly inexorable trend toward higher levels of complexity, specialization and sociopolitical control.”
  • Eventually, societies we would recognize as similar to our own would emerge, “large, heterogeneous, internally differentiated, class structured, controlled societies in which the resources that sustain life are not equally available to all.”
  • Something more than the threat of violence would be necessary to hold them together, a delicate balance of symbolic and material benefits that Tainter calls “legitimacy,” the maintenance of which would itself require ever more complex structures, which would become ever less flexible, and more vulnerable, the more they piled up.
  • Social complexity, he argues, is inevitably subject to diminishing marginal returns. It costs more and more, in other words, while producing smaller and smaller profits.
  • Take Rome, which, in Tainter's telling, was able to win significant wealth by sacking its neighbors but was thereafter required to maintain an ever larger and more expensive military just to keep the imperial machine from stalling — until it couldn’t anymore.
  • This is how it goes. As the benefits of ever-increasing complexity — the loot shipped home by the Roman armies or the gentler agricultural symbiosis of the San Juan Basin — begin to dwindle, Tainter writes, societies “become vulnerable to collapse.”
  • haven’t countless societies weathered military defeats, invasions, even occupations and lengthy civil wars, or rebuilt themselves after earthquakes, floods and famines?
  • Only complexity, Tainter argues, provides an explanation that applies in every instance of collapse.
  • Complexity builds and builds, usually incrementally, without anyone noticing how brittle it has all become. Then some little push arrives, and the society begins to fracture.
  • A disaster — even a severe one like a deadly pandemic, mass social unrest or a rapidly changing climate — can, in Tainter’s view, never be enough by itself to cause collapse
  • The only precedent Tainter could think of, in which pandemic coincided with mass social unrest, was the Black Death of the 14th century. That crisis reduced the population of Europe by as much as 60 percent.
  • Whether any existing society is close to collapsing depends on where it falls on the curve of diminishing returns.
  • The United States hardly feels like a confident empire on the rise these days. But how far along are we?
  • Scholars of collapse tend to fall into two loose camps. The first, dominated by Tainter, looks for grand narratives and one-size-fits-all explanations
  • The second is more interested in the particulars of the societies they study
  • Patricia McAnany, who teaches at the University of North Carolina at Chapel Hill, has questioned the usefulness of the very concept of collapse — she was an editor of a 2010 volume titled “Questioning Collapse” — but admits to being “very, very worried” about the lack, in the United States, of the “nimbleness” that crises require of governments.
  • We’re too vested and tied to places.” Without the possibility of dispersal, or of real structural change to more equitably distribute resources, “at some point the whole thing blows. It has to.”
  • In Turchin’s case the key is the loss of “social resilience,” a society’s ability to cooperate and act collectively for common goals. By that measure, Turchin judges that the United States was collapsing well before Covid-19 hit. For the last 40 years, he argues, the population has been growing poorer and more unhealthy as elites accumulate more and more wealth and institutional legitimacy founders. “The United States is basically eating itself from the inside out,
  • Inequality and “popular immiseration” have left the country extremely vulnerable to external shocks like the pandemic, and to internal triggers like the killings of George Floyd
  • Societies evolve complexity, he argues, precisely to meet such challenges.
  • Eric H. Cline, who teaches at the George Washington University, argued in “1177 B.C.: The Year Civilization Collapsed” that Late Bronze Age societies across Europe and western Asia crumbled under a concatenation of stresses, including natural disasters — earthquakes and drought — famine, political strife, mass migration and the closure of trade routes. On their own, none of those factors would have been capable of causing such widespread disintegration, but together they formed a “perfect storm” capable of toppling multiple societies all at once.
  • Collapse “really is a matter of when,” he told me, “and I’m concerned that this may be the time.”
  • In “The Collapse of Complex Societies,” Tainter makes a point that echoes the concern that Patricia McAnany raised. “The world today is full,” Tainter writes. Complex societies occupy every inhabitable region of the planet. There is no escaping. This also means, he writes, that collapse, “if and when it comes again, will this time be global.” Our fates are interlinked. “No longer can any individual nation collapse. World civilization will disintegrate as a whole.”
  • If it happens, he says, it would be “the worst catastrophe in history.”
  • The quest for efficiency, he wrote recently, has brought on unprecedented levels of complexity: “an elaborate global system of production, shipping, manufacturing and retailing” in which goods are manufactured in one part of the world to meet immediate demands in another, and delivered only when they’re needed. The system’s speed is dizzying, but so are its vulnerabilities.
  • A more comprehensive failure of fragile supply chains could mean that fuel, food and other essentials would no longer flow to cities. “There would be billions of deaths within a very short period,” Tainter says.
  • If we sink “into a severe recession or a depression,” Tainter says, “then it will probably cascade. It will simply reinforce itself.”
  • Tainter tells me, he has seen “a definite uptick” in calls from journalists: The study of societal collapse suddenly no longer seems like a purely academic pursuit
  • Turchin is keenly aware of the essential instability of even the sturdiest-seeming systems. “Very severe events, while not terribly likely, are quite possible,” he says. When he emigrated from the U.S.S.R. in 1977, he adds, no one imagined the country would splinter into its constituent parts. “But it did.”
  • He writes of visions of “bloated bureaucracies” becoming the basis of “entire political careers.” Arms races, he observes, presented a “classic example” of spiraling complexity that provides “no tangible benefit for much of the population” and “usually no competitive advantage” either.
  • It is hard not to read the book through the lens of the last 40 years of American history, as a prediction of how the country might deteriorate if resources continued to be slashed from nearly every sector but the military, prisons and police.
  • The more a population is squeezed, Tainter warns, the larger the share that “must be allocated to legitimization or coercion.
  • And so it was: As U.S. military spending skyrocketed — to, by some estimates, a total of more than $1 trillion today from $138 billion in 1980 — the government would try both tactics, ingratiating itself with the wealthy by cutting taxes while dismantling public-assistance programs and incarcerating the poor in ever-greater numbers.
  • “As resources committed to benefits decline,” Tainter wrote in 1988, “resources committed to control must increase.”
  • The overall picture drawn by Tainter’s work is a tragic one. It is our very creativity, our extraordinary ability as a species to organize ourselves to solve problems collectively, that leads us into a trap from which there is no escaping
  • Complexity is “insidious,” in Tainter’s words. “It grows by small steps, each of which seems reasonable at the time.” And then the world starts to fall apart, and you wonder how you got there.
  • Perhaps collapse is not, actually, a thing. Perhaps, as an idea, it was a product of its time, a Cold War hangover that has outlived its usefulness, or an academic ripple effect of climate-change anxiety, or a feedback loop produced by some combination of the two
  • if you pay attention to people’s lived experience, and not just to the abstractions imposed by a highly fragmented archaeological record, a different kind of picture emerges.
  • Tainter’s understanding of societies as problem-solving entities can obscure as much as it reveals
  • Plantation slavery arose in order to solve a problem faced by the white landowning class: The production of agricultural commodities like sugar and cotton requires a great deal of backbreaking labor. That problem, however, has nothing to do with the problems of the people they enslaved. Which of them counts as “society”?
  • Since the beginning of the pandemic, the total net worth of America’s billionaires, all 686 of them, has jumped by close to a trillion dollars.
  • If societies are not in fact unitary, problem-solving entities but heaving contradictions and sites of constant struggle, then their existence is not an all-or-nothing game.
  • Collapse appears not as an ending, but a reality that some have already suffered — in the hold of a slave ship, say, or on a long, forced march from their ancestral lands to reservations faraway — and survived.
  • The current pandemic has already given many of us a taste of what happens when a society fails to meet the challenges that face it, when the factions that rule over it tend solely to their own problems
  • the real danger comes from imagining that we can keep living the way we always have, and that the past is any more stable than the present.
  • If you close your eyes and open them again, the periodic disintegrations that punctuate our history — all those crumbling ruins — begin to fade, and something else comes into focus: wiliness, stubbornness and, perhaps the strongest and most essential human trait, adaptability.
  • When one system fails, we build another. We struggle to do things differently, and we push on. As always, we have no other choice.

  • While the studies cover many different topics, the subject of an individualistic or holistic thinking style is noteworthy.
  • In one study, complex images were shown to test subjects from East Asia and North America. The scientists tracked the eye movements of the participants in order to gauge where their attention was focused. It was found that the Chinese participants spent more time looking at the background of the image, while the Americans tended to focus on the main object in the picture. Holistic and individualistic thinking manifested in one clear example.
  • Of course, these tendencies are generalizations.

  • One is that the staple food of a region may have something to do with it. This is excellently seen in China, where the northern half of the country grows wheat and the southern half grows rice. Rice growing is a labour intensive activity, that requires the coordination of several neighboring farms to do properly. Wheat farming, on the other hand, takes much less work and does not require coordination of irrigation systems in order to work.
  • Even today, more than 100 years after the colonization effort, the effects of living in a society that was so recently a frontier show up in individual and holistic thinking tests. With residents of Hokkaido demonstrating tendencies towards individualism to a larger extent than the rest of the Japanese population.

    I really like the author stating that "Of course, these tendencies are generalizations." This shows that this study is not to categorize people into east and west, two groups. But this tendency is worth-noticing. The trials presented in the article shows different possibilities of why there is a difference. I think this cultural difference is similar to why Australia has very distinctive animal compare to the other continents. Since in the ancient times, westerners and easterners are isolated to each other, they took different approaches to develop their civilization. However, I really like the author emphasizing that this difference is not a stereotyping, it is the result of population analysis and observations. --Sissi (2/6/2017)

  • For the BRIC rising economies -- Brazil, Russia, India, and China -- what can be learned by looking at the rise of powers throughout history?
  • production in "all organic economies was set by the annual cycle of plant growth" -- it limits food, fuel, fiber, and building materials. Coal changed all that. By digging into the earth to get minerals instead of growing fuel on the earth, you get a vastly more efficient source of fuel and completely change the rules of the game. You've shifted from an organic economy, as he calls it, to an energy-rich economy. But the economic reprieve the fossil fuels offered could be nearing an end, as global supply becomes more competitive.
  • Historians still debate the nature and causes of the Industrial Revolution, but one thing they seem to agree on is that the it wasn't just industrial -- it was demographic and agricultural as well. Prior to the Industrial Revolution, populations all over the globe had non-negotiable checks on their growth: too many people and you get ecological crises and famines to push the number back down. In the 18th and 19th centuries, England managed to solve this problem, with tremendous leaps in population and urbanization as a result.

  • What the rise of the BRICs symbolizes to both panicked individuals in the West and optimistic ones elsewhere is a radical shift in the geography of power -- a catch-up or reversal of the Western global dominance that was established with the Industrial Revolution.
  • developing countries won't be able to follow the West's path to becoming rich, because that path required certain things that were largely particular to that one period in history.
  • The challenge ahead for the BRICs, then, is to figure out how to maintain growth in a world where the vast new frontier opened up by the Industrial Revolution appears to be closing. The BRICs can play the West's game better than the West, both through technological innovation and population growth, but only for so long. The whole world has to figure out a way of dealing with energy and agriculture.

  • If we had the same income distribution in the United States that we did in 1979, the top 1 percent would have $1 trillion less today [in annual income], and the bottom 80 percent would have $1 trillion more. That works out to about $700,000 [a year for] for a family in the top 1 percent, and works out to about $11,000 a year for a family in the bottom 80 percent.
  • The lion’s share of the income of the top 1 percent is concentrated in the top 0.1 percent and 0.01 percent. The average income of the top 1 percent in 2013, according to data provided by Emmanuel Saez, a Berkeley economist, was $1.2 million, for the top 0.1 percent, $5.3 million, and for the top 0.01 percent, $24.9 million.
  • In other words, any attempt to correct the contemporary pattern in income distribution would require large and controversial changes in tax policy, regulation of the workplace, and intervention in the economy to expand employment and to raise wages.

  • To counter the weak employment market, Summers called for major growth in government expenditures to fill needs that the private sector is not addressing:In our society, whether it is taking care of the young or taking care of the old, or repairing a lot that needs to be repaired, there is a huge amount of very valuable work that needs to be done. It’s much less clear, to use a modern phrase, that there’s a viable business model for getting it done. And I guess the reason why I think there is going to need to be a lot of reflection on the role of government going forward is that, if I’m right, that there’s vitally important work to be done for which there is no standard capital business model that will get it done. That suggests important roles for public policy.
  • the report calls for tax and regulatory policies to encourage employee ownership, the strengthening of collective bargaining rights, regulations requiring corporations to provide fringe benefits to employees working for subcontractors, a substantial increase in the minimum wage, sharper overtime pay enforcement, and a huge increase in infrastructure appropriations – for roads, bridges, ports, schools – to spur job creation and tighten the labor market.
  • Summers also calls for significant increases in the progressivity of the United States tax system.
  • He advocates aggressive steps to eliminate “rents” — profits that result from monopoly or other forms of government protection from competition. Summers favors attacking rents in the form of “exclusionary zoning practices” that bid up the price of housing, “excessively long copyright” protections, and financial regulations “providing implicit subsidies to a fortunate minority.”
  • Signaling that he now finds himself on common ground with stalwarts of the Democratic left like Elizabeth Warren and Joe Stiglitz, Summers adds, “Government needs to try to make sure everyone can get access to financial markets on an equal basis.”
  • Summers supports looking past income inequality to the distribution of wealth. During our conversation, he pointed out that “a large fraction of capital gains escapes taxation entirely” through “the stepped up basis at death.”
  • The idea that an economy could suffer from a persistent shortage of demand is an enormous switch for Summers or anyone who had been adhering to the economic orthodoxy in the three decades prior to the crisisin 2008. Baker goes on to argue that Summers “now recognizes that the financial system needs serious regulation.”
  • Many of the policies outlined by Summers — especially on trade, taxation, financial regulation and worker empowerment — are the very policies that divide the Wall-Street-corporate wing from the working-to-middle-class wing of the Democratic Party. Put another way, these policies divide the money wing from the voting wing.
  • Summers has forced out in the open a set of choices that Hillary Clinton has so far avoided, choices that even if she attempts to elide them will amount to a signal of where her loyalties lie.
  • “The core problem,” according to Summers, is thatthere aren’t enough jobs, and if you help some people, you can help them get the jobs, but then someone else won’t get the jobs. And unless you’re doing things that are affecting the demand for jobs, you’re helping people win a race to get a finite number of jobs, and there are only so many of them.
  • he is “all for” more schooling and job training, but as an answer to the problems of the job marketplace, “it is fundamentally an evasion.”
  • Summers’s analysis of current economic conditions suggests that free market capitalism, as now structured, is producing major distortions. These distortions, in his view, have resulted in gains of $1 trillion annually to those at the top of the pyramid, and losses of $1 trillion every year to those in the bottom 80 percent.
  • Summers’s ascendance is a reflection of the abandonment by much of the party establishment of neo-liberal thinking, premised on the belief that unregulated markets and global trade would produce growth beneficial to worker and C.E.O. alike.
  • Larry Summers, who withdrew his candidacy for the chairmanship of the Federal Reserve under pressure from the liberal wing of the Democratic Party in 2013, has emerged as the party’s dominant economic policy strategist. The former Treasury secretary’s evolving message has won over many of his former critics.

  • “Just as we are seeing a step function increase in the spread of AI, something else is happening: the rise of ultra-nationalism, rightwing authoritarianism and fascism,” she said.
  • All of these movements have shared characteristics, including the desire to centralize power, track populations, demonize outsiders and claim authority and neutrality without being accountable. Machine intelligence can be a powerful part of the power playbook, she said.
  • “We should always be suspicious when machine learning systems are described as free from bias if it’s been trained on human-generated data,” Crawford said. “Our biases are built into that training data.

  • Another area where AI can be misused is in building registries, which can then be used to target certain population groups. Crawford noted historical cases of registry abuse, including IBM’s role in enabling Nazi Germany to track Jewish, Roma and other ethnic groups with the Hollerith Machine, and the Book of Life used in South Africa during apartheid.
  • Donald Trump has floated the idea of creating a Muslim registry. “We already have that. Facebook has become the default Muslim registry of the world,
  • Crawford was concerned about the potential use of AI in predictive policing systems, which already gather the kind of data necessary to train an AI system. Such systems are flawed, as shown by a Rand Corporation study of Chicago’s program. The predictive policing did not reduce crime, but did increase harassment of people in “hotspot” areas

  • Another worry related to the manipulation of political beliefs or shifting voters, something Facebook and Cambridge Analytica claim they can already do. Crawford was skeptical about giving Cambridge Analytica credit for Brexit and the election of Donald Trump, but thinks what the firm promises – using thousands of data points on people to work out how to manipulate their views – will be possible “in the next few years”.
  • “This is a fascist’s dream,” she said. “Power without accountability.”
  • Such black box systems are starting to creep into government. Palantir is building an intelligence system to assist Donald Trump in deporting immigrants.
  • Crawford argues that we have to make these AI systems more transparent and accountable. “The ocean of data is so big. We have to map their complex subterranean and unintended effects.”
  • Crawford has founded AI Now, a research community focused on the social impacts of artificial intelligence to do just this “We want to make these systems as ethical as possible and free from unseen biases.”
