The Structure of Scientific Revolutions - Wikipedia, the free encyclopedia - 0 views

  • The Structure of Scientific Revolutions by Thomas S. Kuhn, is an analysis of the history of science, published in 1962 by the University of Chicago Press. Its publication was a landmark event in the history, philosophy, and sociology of scientific knowledge and it triggered an ongoing worldwide assessment and reaction in—and beyond—those scholarly communities. In this work, Kuhn challenged the then prevailing view of progress in "normal science". Scientific progress had been seen primarily as "development-by-accumulation" of accepted facts and theories. Kuhn argued for an episodic model in which periods of such conceptual continuity in normal science were interrupted by periods of revolutionary science.
  • What is arguably the most famous example of a revolution in scientific thought is the Copernican Revolution. In Ptolemy's school of thought, cycles and epicycles (with some additional concepts) were used for modeling the movements of the planets in a cosmos that had a stationary Earth at its center. As accuracy of celestial observations increased, complexity of the Ptolemaic cyclical and epicyclical mechanisms had to increase to maintain the calculated planetary positions close to the observed positions. Copernicus proposed a cosmology in which the Sun was at the center and the Earth was one of the planets revolving around it.
  • Copernicus' contemporaries rejected his cosmology, and Kuhn asserts that they were quite right to do so: Copernicus' cosmology lacked credibility.

  • Those scientists who possess an exceptional ability to recognize a theory's potential will be the first whose preference is likely to shift in favour of the challenging paradigm. There typically follows a period in which there are adherents of both paradigms. In time, if the challenging paradigm is solidified and unified, it will replace the old paradigm, and a paradigm shift will have occurred.
  • In any community of scientists, Kuhn states, there are some individuals who are bolder than most. These scientists, judging that a crisis exists, embark on what Thomas Kuhn calls revolutionary science, exploring alternatives to long-held, obvious-seeming assumptions. Occasionally this generates a rival to the established framework of thought. The new candidate paradigm will appear to be accompanied by numerous anomalies, partly because it is still so new and incomplete. The majority of the scientific community will oppose any conceptual change, and, Kuhn emphasizes, so they should. To fulfill its potential, a scientific community needs to contain both individuals who are bold and individuals who are conservative.
  • One of the aims of science is to find models that will account for as many observations as possible within a coherent framework. Together, Galileo's rethinking of the nature of motion and Keplerian cosmology represented a coherent framework that was capable of rivaling the Aristotelian/Ptolemaic framework.
  • Chronologically, Kuhn distinguishes between three phases. The first phase, which exists only once, is the pre-paradigm phase, in which there is no consensus on any particular theory, though the research being carried out can be considered scientific in nature. This phase is characterized by several incompatible and incomplete theories.
  • If the actors in the pre-paradigm community eventually gravitate to one of these conceptual frameworks and ultimately to a widespread consensus on the appropriate choice of methods, terminology and on the kinds of experiment that are likely to contribute to increased insights, then the second phase, normal science, begins, in which puzzles are solved within the context of the dominant paradigm. As long as there is consensus within the discipline, normal science continues.
  • Over time, progress in normal science may reveal anomalies, facts that are difficult to explain within the context of the existing paradigm. While usually these anomalies are resolved, in some cases they may accumulate to the point where normal science becomes difficult and where weaknesses in the old paradigm are revealed. Kuhn refers to this as a crisis. Crises are often resolved within the context of normal science. However, after significant efforts of normal science within a paradigm fail, science may enter the third phase, that of revolutionary science, in which the underlying assumptions of the field are reexamined and a new paradigm is established. After the new paradigm's dominance is established, scientists return to normal science, solving puzzles within the new paradigm.
  • SSR is viewed by postmodern and post-structuralist thinkers as having called into question the enterprise of science by demonstrating that scientific knowledge is dependent on the culture and historical circumstances of groups of scientists rather than on their adherence to a specific, definable method.
  • SSR has also been embraced by creationists who see creationism as an incommensurate worldview in contrast to naturalism while holding science as a valuable tool.[7]

A Family Tree in Every Gene - 0 views

  • Who speaks of "racial stocks" anymore? After all, to do so would be to speak of something that many scientists and scholars say does not exist. If modern anthropologists mention the concept of race, it is invariably only to warn against and dismiss it. Likewise many geneticists. "Race is social concept, not a scientific one," according to Dr. Craig Venter—and he should know, since he was first to sequence the human genome.
  • But now, perhaps, that is about to change
  • The dominance of the social construct theory can be traced to a 1972 article by Dr. Richard Lewontin, a Harvard geneticist, who wrote that most human genetic variation can be found within any given "race." If one looked at genes rather than faces, he claimed, the difference between an African and a European would be scarcely greater than the difference between any two Europeans.

  • Three decades later, it seems that Dr. Lewontin's facts were correct, and have been abundantly confirmed by ever better techniques of detecting genetic variety. His reasoning, however, was wrong. His error was an elementary one, but such was the appeal of his argument that it was only a couple of years ago that a Cambridge University statistician, A. W. F. Edwards, put his finger on it.
  • Genetic variants that aren't written on our faces, but that can be detected only in the genome, show similar correlations. It is these correlations that Dr. Lewontin seems to have ignored. In essence, he looked at one gene at a time and failed to see races. But if many—a few hundred—variable genes are considered simultaneously, then it is very easy to do so. Indeed, a 2002 study by scientists at the University of Southern California and Stanford showed that if a sample of people from around the world are sorted by computer into five groups on the basis of genetic similarity, the groups that emerge are native to Europe, East Asia, Africa, America and Australasia—more or less the major races of traditional anthropology.

    "A Family Tree in Every Gene By Armand Marie Leroi Published on: Jun 07, 2006 Armand Marie Leroi, an evolutionary developmental biologist at Imperial College in London, is the author of Mutants: On Genetic Variety and the Human Body." This Article is a fairly sensible, nuanced, defense of the race concept based on recent genetic analyses of hundreds of genetic variables at a time.

The Fierce anthropologists - 0 views

  • Chagnon, aged 63, is one of the most distinguished anthropologists alive.
  • But he has also made plenty of enemies. Some are professional. Chagnon’s explanation of Yanomamö violence was deeply controversial, both. among people who understand it as a general theory of human nature (which it is meant to be), and among those who see it only as a particular explanation of Yanomamö culture. The Yanomamo are not, in fact, exceptionally violent by the standards of aboriginal people.
  • Chagnon’s enemies believe the Yanomamö sometimes fought because he had paid them to act for his cameras.
  • ...7 more annotations...
  • It was at this stage that a journalist named Patrick Tierney, who had earlier written a book claiming that human sacrifice survived among some Indian Andean tribes, spent a year there. Darkness in El Dorado, the book on Tierney’s adventures among the gold miners which was to have been published by Viking in 1995, never appeared. Instead, last year WW Norton announced it was publishing his book, which had now become a tale of ‘How scientists and journalists devastated the Amazon’,
  • Chagnon had enjoyed good relations with the Roman Catholic Salesian missionaries who control access to most of the region. Indeed, the relationship was so good, he told me, that he was asked by one priest to arrange the murder of another missionary who had gone off the rails and taken up with a Yanomamö concubine far up the river (he declined). But the relationship started to unravel as the Yanomamö grew more famous.
  • Some of his enemies are personal. He is by all accounts a boisterous man (he calls the two professors who have attacked him ‘absolute zeros’). Moving among the Yanomamö, Chagnon had the sort of personality — or discovered it in himself— that could thrive and impose itself on a brutal and treacherous political environment. For the first months of his fieldwork, while he was learning the language, the Yanomamö systematically lied to him. He needed to collect genealogies in order to trace the histories of the people he moved among, yet among the Yanomamö there is a taboo against using people’s names, and especially’ the names of the dead.
  • Neel and Chagnon ‘greatly exacerbated’ and probably started the epidemic of measles that killed so many Yanomamö. They caused or at least worsened the epidemic by their use of a virulent vaccine (Edmonston B) that was quite wrong for use on a population like this with no prior exposure to measles.
  • The most Tierney would concede at a press conference is that ‘the question of transmissibility [whether the vaccine could have caused the epidemic] is still up in the air’, at which point Dr Yvonne Maldonado, the expert on infectious diseases and childhood immunisation on the panel, finally lost her cool: ‘You’re not a physician, not an epidemiologist and not even a scientist as far as I can tell... There is absolutely no evidence for transmissibility.’ By now she was almost shouting at the man two feet away from her. ‘There is no evidence! The vaccine did not cause an epidemic. It did not cause deaths.’
  • No one doubts that the situation of the Yanomamo and of the other indigenous peoples of South America is truly dreadful.
  • When I pressed Professor Sponsel on the question of whether he should have checked these damaging allegations that a colleague had been responsible for hundreds of deaths before passing them on. he grew quite heated. ‘I’m not a medical doctor. My role, ethically, was to alert the AAA because of my concern with human rights. After that, the only role I had was to respond to questions when people asked me in a civil, polite manner. Terry Turner and I wrote that memo to the two top people in the organisation and sent copies to four other people in the committee on ethics. Whoever leaked it is the one who should be sanctioned or censured.

  • this of course conflicted with ethical or moral principles.
  • How did that measles epidemic get started? Chagnon: It was introduced to the Yanomamö in Brazil. The young daughter of a missionary brought it back from a trip to Manaus. The incubation period is about two weeks—she was perfectly healthy when she left Manaus. There’s good documentation of this origin of the 1968 epidemic. The missionary published this account, and it should have ended there. All serious investigators accept this account.
  • First published in 1968, Yanomamö: The Fierce People is arguably the best selling anthropology textbook of all time (move over Margaret Mead’s Coming of Age in Samoa). But Chagnon’s career has been as tumultuous as it has been epic. For decades his peers hotly debated his view that humans had, as he describes it, an "evolved nature in addition to a learned nature." Then a book released in 2000, Darkness in El Dorado: How Scientists and Journalists Devastated the Amazon, by Patrick Tierney, turned those academic skirmishes into all-out war on Chagnon and his career.
  • a new movie, Secrets of the Tribe, made by Brazilian filmmaker Jose Padilha and premiered at the Sundance Film Festival in January, resurrects the old charges, again insinuating Chagnon’s guilt in the Amazon measles affair. And once again, Chagnon is waging a defense.
  • Chagnon: What I do is collect factual, empirical data as distinct from dealing only in subjective stories like myths as some cultural anthropologists do. I’m trying to push the study of societies toward an empirical set of scientific procedures. I do, however, also collect and study myths, the understanding of which lies more in the arena of comparative literature … which can also be studied scientifically, even with evolutionary theory, as some of my former students do.
  • We were able to show with my census data that 25 people died of an upper respiratory infection a day or two before, including the headman and a very famous leader I had known for 25 years.
  • In July of 1993 Brazilian gold miners brutally attacked a Yanomamö village, decapitating women and children with machetes and murdering about a dozen people in all.
  • In fact, you actually allowed Padilha access to the valuable footage that you and filmmaker Timothy Asch shot of the Yanomamö.
  • persuaded me about his firm commitment to truth, the scientific method, and objectivity in reporting, I allowed him access to my films. Then when the film came out it was just a piece of trash.

Kenan Malik's review of 'Darkness in El Dorado' by Patrick Tierney - 0 views

  • In the twentieth century, the consequences of racial science led anthropologists to reject naturalistic explanations and to see human behaviour as dictated largely by culture, not biology
  • all too often anthropologists saw what they wanted to
  • The most prominent of the new generation of sociobiological anthropologists was the American Napoleon Chagnon
  • ...21 more annotations...
  • Chagnon presented the Yanomamo as a fierce, primitive tribe whose mores opened the window onto our own past ('our contemporary ancestors' as Chagnon has described them).
  • linked Yanomami violence to genetic success
  • Chagnon revealed that men who had killed had more than twice as many wives and three times as many offspring as non-killers. The idea that murderous violence enhanced Yanomami men's reproductive success was manna for sociobiologists.
  • Chagnon's paper is one of the most widely cited scientific studies of all time - and one of the most fiercely criticised.
  • Tierney presents a convincing case that Chagnon has consistently overestimated Yanomami violence, and that he himself was responsible for fomenting much of it
  • Patrick Tierney's Darkness in El Dorado
  • Tierney accuses Chagnon, among other things, of scientific fraud, sexual abuse, political corruption and, most sensationally, genocide
  • Chagnon, and his mentor the geneticist James Neel, may have deliberately infected Yanomami with measles, beginning an epidemic that wiped out hundreds, perhaps even thousands, of people, as part of a grotesque experiment to test the impact of natural selection on primitive groups.
  • Tierney's book, they claim, is 'a case study of the dangers in science of the uncontrolled ego'.
  • humans are an inherently violent and aggressive species. Chagnon himself has said that violence 'may be the principal driving force behind the evolution of culture'
  • Chagnon had changed the political balance between different Yanomami groups by favouring some over others, and by selectively providing steel goods and weapons to certain groups. Chagnon was apparently given to bursting into villages decorated in war paint and brandishing a shotgun. Yanomami men soon realized that their own displays of aggression would be rewarded with machetes and other highly prized tools.
  • Chagnon was an active participant in the wars. Yanomami men were fighting for access not to women but to Chagnon himself.
  • In 1968 a measles epidemic decimated the Yanomami population. At exactly the same time, Chagnon had embarked on an expedition to the Amazon under the leadership of the geneticist James Neel. During that expedition the two men initiated a programme of inoculation against measles to protect the Yanomamo. According to Tierney, however, it was that very programme of inoculation that caused the epidemic in the first place.
  • Tierney quotes several people who hint darkly that an epidemic might have been exactly what Neel wanted. Moreover, once the epidemic was under way, Neel and Chagnon 'refused to provide any medical assistance to the sick and dying Yanomami', insisting that 'they were there only to observe and record the epidemic, and that they must stick strictly to their roles as scientists, not provide medical help.'
  • Neel rejected the medical orthodoxy that the Yanomami were genetically susceptible to measles, believing that the Yanomamis' survival-of-the-fittest lifestyle had given them immune systems more robust than those of us in pampered modern societies have. The epidemic would prove Neel's theories.
  • Tierney produces very little direct evidence to back up his monstrous claims.
  • The consensus is that the measles epidemic began before Chagnon and Neel arrived in Venezuela, and that they initiated their inoculation programme precisely because they were aware of the earlier outbreak
  • used Edmonston B
  • after receiving advice from the Venezuelan government
  • In many ways Darkness in El Dorado raises more questions about Tierney's motives, and those of Chagnon's other critics, than it does about Chagnon's own work.
  • What Tierney is questioning is the very possibility of a scientific anthropology. Anthropologists cannot simply be observers, as traditional scientific objectivity requires, but must actively take sides in any political struggle involving the peoples they are studying. And in such a struggle the norms of scientific objectivity become subordinate to the political aims
  •  
    I find this article interesting because it not only describes Tierney's point of view of Chagnon in 'Darkness in El Dorado' but it questions Tierney's own credibility of accusing Chagnon for such outrageous crimes.  It describes his reasoning behind all his claims but also points out the last of factual evidence he presents with them.

'Ten Commandments' of race and genetics issued - science-in-society - 17 July 2008 - Ne... - 0 views

  • Even with the human genome in hand, geneticists are split about how to deal with issues of race, genetics and medicine.
  • Some favor using genetic markers to sort humans into groups based on ancestral origin - groups that may show meaningful health differences. Others argue that genetic variations across the human species are too gradual to support such divisions and that any categorisation based on genetic differences is arbitrary.
  • 1. All races are created equal No genetic data has ever shown that one group of people is inherently superior to another. Equality is a moral value central to the idea of human rights; discrimination against any group should never be tolerated.
  • ...1 more annotation...
  • 2. An Argentinian and an Australian are more likely to have differences in their DNA than two Argentinians Groups of human beings have moved around throughout history. Those that share the same culture, language or location tend to have different genetic variations than other groups. This is becoming less true, though, as populations mix.
  •  
    This is a short list of good points to be made about Genetics and the concept of race.  I find that it is often difficult for students to wrap their heads around genetic variation and race.  I will try my best to explain it in the coming week.
