  • Quote: Phillip Tobias on the study of race

    Thu, 2013-05-16 22:15 -- John Hawks

    I was doing research on another topic, and ran across an obituary of Phillip Tobias that I hadn't seen: "Phillip Tobias, SA's great scientist and human being, has gone back to earth". I thought this direct quote from Tobias worth sharing:

    In a society in which the question of race has come to loom as largely as it does in South Africa, there is, I believe, a positive duty on a scientist who has made a special study of race to make known the facts and the most highly confirmed hypotheses about race, whenever a suitable opportunity presents itself. I should be failing, therefore, in my academic duty, if I were to hold my peace and say nothing about race, simply because the scientific truth about race runs counter to some or all of the assumptions underlying or influencing the race policies of this country. In no field is the need of guidance from qualified scientists more imperative than in this very subject of race.

    The rest of the article is really good, as it describes both Tobias' work on fossil hominins and his activism against apartheid.

  • An Australopithecus sediba paean

    Thu, 2013-04-25 08:32 -- John Hawks

    Kate Wong: "Is Australopithecus sediba the Most Important Human Ancestor Discovery Ever?"

    Second—and this may sound a little insidery, but it’s critical–the way Berger and his collaborators are studying the finds and disseminating what they learn represents a real departure from the cloak-and-dagger manner in which paleoanthropological investigations often proceed. Berger has assembled a huge team of specialists to work on the remains and has made the project open access, with a policy of granting permission to any paleoanthropologist who asks to see the original fossils. He has also sent out scores of replicas to institutions around the world, and routinely brings casts of the bones—even ones that his team has yet to formally describe–to professional meetings to share with other researchers. This can only improve the quality of the science that comes out of the project and may well inspire other teams to be more forthcoming with their own data.

    Malapa is the perfect site at the perfect time. Many people have scoured that area looking for something like Malapa. If they had found it in 1950 we would have the skeletons, but would have lost much of the context. The open approach is fundamental to the science because it enables the best people to do their best work.

    Is Au. sediba the most important ever? As Wong writes, we must match the find with the moment. Clearly right now, Malapa poses fundamentally new questions and provides evidence to address them. It is not alone: Denisova likewise has produced (and is still producing) vast reams of new data and raising new, unforeseen questions. Other key sites belong in this league: Sima de los Huesos, Dmanisi.

    We have yet to see the full importance of these sites, as they are still unfolding. It is our job to find the contradictions between these new finds and our earlier hypotheses, and use them to discover the real story.

  • Anthropology's Spinal Tap problem

    Tue, 2013-02-26 16:25 -- John Hawks

    The Thesis Whisperer brings up the topic of prolonged rudeness in academic culture: "Academic assholes and the circle of niceness". When I write that it's time to "reclaim the name 'anthropology' from this earlier generation", I mean that the elite discourse within the field has become toxic. Rude behavior often yields short-term gains, but has obvious long-term costs for the discipline as a whole:

    How does it happen? The budding asshole has learned, perhaps subconsciously, that other people interrupt them less if they use stronger language. They get attention: more air time in panel discussions and at conferences. Other budding assholes will watch strong language being used and then imitate the behaviour. No one publicly objects to the language being used, even if the student is clearly upset, and nasty behaviour gets reinforced. As time goes on the culture progressively becomes more poisonous and gets transmitted to the students. Students who are upset by the behaviour of academic assholes are often counselled, often by their peers, that “this is how things are done around here” . Those who refuse to accept the culture are made to feel abnormal because, in a literal sense, they are – if being normal is to be an asshole.

    Not all academic cultures are badly afflicted by assholery, but many are. I don’t know about you, but seen this way, some of the sicker academic cultures suddenly make much more sense.

    Yes, anthropology has been affected. Picking academic vendettas used to be a great way to get famous. The students -- at least the normal students -- suffered. The field has selected for bad behavior.

    Many elite anthropologists still consider the New York Times to be an arbiter of quality work. That is, if you are featured in the Times, you are visible to the elite. Yet the Times itself has become actively hostile to cultural anthropology as a field, selecting the worst instances of bad behavior for promotion and coverage. Some of my friends have been agitated for the last week waiting breathlessly for the Times to publish letters decrying the recent coverage.

    Seriously.

    You know that scene in This Is Spinal Tap?

    David St. Hubbins: I do not, for one, think that the problem was that the band was down. I think that the problem *may* have been, that there was a Stonehenge monument on the stage that was in danger of being *crushed* by a *dwarf*. Alright? That tended to understate the hugeness of the object.

    Ian Faith: I really think you're just making much too big a thing out of it.

    Derek Smalls: Making a big thing out of it would have been a good idea.

    Yeah. That one. The curtain has risen on the old band, and they're playing behind a Stonehenge monument that can be crushed by a dwarf. Please, somebody, lower the curtain.

  • More on the reclamation proclamation

    Tue, 2013-02-26 15:22 -- John Hawks

    Michael E. Smith comments on the Chagnon/Sahlins flap from the perspective of archaeology: "Chagnon, Sahlins, and science":

    What about archaeology? Are we exempt from this kind of serious but silly debate? We certainly have our sociobiologists and our cultural explanations partisans. Mostly they talk past one another, and if they do happen to engage, discourse takes the form of "Is so!" "Is not!" "Is too!" I've commented on a parallel manifestation of the serious but silly debates about the role of drought in the Maya collapse, and archaeological opinions on Jared Diamond's collapse book.

    When we allow personal ideological bias rule to our scholarly work, we limit the value of our research to answer real questions and to contribute to broader social and scientific debates. If you have an ideological axe to grind, either leave scholarship and go into politics, or else find ways to achieve a level of scholarly objectivity in your research and writing.

    Oh, how I wish I didn't have a grant proposal to finish tonight. More when I have a chance...

  • Sahlins and Chagnon

    Mon, 2013-02-25 10:10 -- John Hawks

    Essential reading today for anthropologists: Serena Golden's account of how Marshall Sahlins resigned from the National Academy of Sciences: "A Protest Resignation".

    Sahlins' resignation highlights two serious and ongoing debates within anthropology: one, the appropriate relationship -- if any -- between anthropologists and the military (Sahlins has previously expressed his opposition to any such involvement); two, the role of hard science within the discipline.

    ...

    Asked to offer his opinion on Sahlins' move, [Napoleon] Chagnon wrote in an e-mail, "I am surprised that Sahlins resigned from the NAS to protest my election last year to the NAS. One possible interpretation is that he is displeased with the gradual swing back to to the academic principle that scientists should tell the truth in their publications...."

    I think it's time to reclaim the name "anthropology" from this earlier generation.

  • Napoleon Chagnon profile

    Wed, 2013-02-13 07:36 -- John Hawks

    The New York Times has a very long and informative profile of Napoleon Chagnon, written by Emily Eakin: "Napoleon Chagnon, America's Most Controversial Anthropologist". The profile is in connection with Chagnon's upcoming book, Noble Savages: My Life Among Two Dangerous Tribes — the Yanomamö and the Anthropologists. The piece does a very nice job of summarizing Chagnon's work, its importance in the field, and how he came to be vilified by many cultural anthropologists of his generation.

    It's full of good paragraphs, and I'm choosing to quote this passage because I love the last sentence:

    Under the influence of Derrida and Foucault, cultural anthropologists turned their gaze on their own “texts” and were alarmed by what they saw. Ethnographies were not dispassionate records of cultural facts but rather unstable “fictions,” shot through with ideology and observer bias.

    This postmodern turn coincided with the disappearance of anthropology’s traditional subjects — indigenous peoples. Even the Yanomami were becoming assimilated, going to mission schools, appearing on television in Caracas and flying to the United States to speak at academic conferences. Traditional fieldwork opportunities may have been drying up, but there was still plenty of work to do exposing anthropologists’ complicity in oppressing “the other.” As one scholar in the journal Current Anthropology put it, “Isn’t it odd that the true enemy of society turns out to be that guy in the office down the hall?”

    An all-too-common tale. The profile is a good way for students and others who may not know the historical background to understand this part of the history of anthropology. Recommended.

  • Quote: Inconsistencies of anthropological theory

    Wed, 2013-02-06 23:39 -- John Hawks

    Courtesy of a Twitter exchange, I was reading Stanley R. Barrett, who in the introduction to his 1984 book, The Rebirth of Anthropological Theory, considers an essential problem: As of 1984, anthropological theory seemingly hadn't gotten any better at explaining social phenomena, despite more than a century of trying.

    Just as sociologists take refuge behind methodology in order to avoid dilemmas in their discipline, anthropologists slip off to the field, the enormous challenge of which soon drives away all other problems.

    I didn't escape quickly enough, and the deeper I delved into the history of anthropological theory, the more inconsistencies I discovered. Scientific knowledge supposedly is cumulative, yet our theoretical orientations have oscillated between polar positions, advancing, repeating, and retracting, but rarely achieving progress. Our methodology rests on the assumption of an orderly universe; yet social life is essentially contradictory, although disguised by numerous mechanisms. A great deal of anthropological analysis has mistaken these mechanisms for underlying reality, which means that the discipline has itself contributed to a distorted view of behaviour. Since its beginnings, anthropology has expressed a dream, a hope for a universe without hate, rancour, or racism, in which the peoples of the world would live together in harmony. Yet it also has aspired toward science, even at the expense of the dream, and the result has sometimes been a discipline that has lost the capacity for moral judgment.

    I don't usually editorialize in my "quotes" posts, but every time I read through this quote, the last two sentences irritate me. The reference to racism and colonialism is transparent, but even so I object. "Aspiring toward science" did not cause anthropologists to "lose the capacity for moral judgment".

  • Phrenology, race and history

    Tue, 2013-02-05 22:01 -- John Hawks

    The movie Django Unchained includes a scene in which the antagonist (a rich, white, plantation owner) expounds on phrenology as a justification of slavery. James Poskett in The Guardian gives the historical context behind racist phrenology. The interesting part is the existence of anti-racist phrenology:

    [I]t wasn't just the slavers. My research revealed that some of the most vocal anti-slavery campaigners of the 19th century were also advocates of phrenology, and used it to justify their stance.

    Lucretia Mott, a particularly uncompromising American abolitionist, sent her children to phrenological lectures and spoke of the "truth of phrenology" in letters to friends. When she visited Britain she stayed with the renowned Scottish phrenologist George Combe, himself an anti-slavery campaigner. Horace Mann, another major figure in abolitionist politics, was so keen on phrenology that he subscribed to the official journal. After becoming president of Antioch College in Ohio, he even boasted in the same sentence that the professors he employed were both "anti-slavery men" and "avowed phrenologists".

    The relation between science, pseudoscience, and highbrow morality in the nineteenth century was counterintuitive. Phrenologists were steampunk witchdoctors.

  • Quote: Fossey on Louis Leakey's sense of humor

    Tue, 2013-01-15 22:21 -- John Hawks

    Dian Fossey, writing in Gorillas in the Mist about her recruitment to study the mountain gorilla:

    Our conversation ended with his assertion that it was mandatory I should have my appendix removed before venturing into the remote wilderness of the gorillas' high altitude habitat in central Africa. I would have agreed to almost anything at that point and promptly made plans for an appendectomy.

    Some six weeks later on returning home from the hospital sans appendix, I found a letter from Dr. Leakey. It began, "Actully there really isn't any dire need for you to have your appendix removed. That is only my way of testing applicants' determination!" This was my first introduction to Dr. Leakey's unique sense of humor.

  • Hooton's complexity

    Wed, 2012-11-21 12:37 -- John Hawks

    Eugene Giles has an article in the new Yearbook of Physical Anthropology that will be of great historical interest to many in the field: "Two faces of Earnest A. Hooton" [1]. Hooton was a central character in physical anthropology, and ultimately his students would come to populate most of the positions in physical anthropology in the United States. It is often said that every student who learns osteology in American schools today is fundamentally taking Hooton's course in the subject. He was born in Wisconsin and received his Ph.D. here at the University of Wisconsin, in classics, after a time in the U.K. as a Rhodes Scholar. In other words, he was scientific royalty. Unlike most, he took that status and became a public intellectual of substantial note, publishing popular articles throughout his lifetime on the topics of evolution, race, and eugenics.

    Giles has accumulated a rich record of biographical details about Hooton, who was a complex figure. I might describe him as embodying the apotheosis of racial science -- dividing up human groups by an involved scheme of "major" and "minor" races, he attempted to categorize human variation into types purported to represent historical connections among peoples. It is not enough to say that this was typical of physical anthropology, because up until 1950 or so, this simply was physical anthropology. Hooton's students were the first generation to really take an alternative approach, and most of them did so only after a substantial period working with racial categories in a nineteenth-century framework.

    Giles approaches crucial questions: Can a racial scientist be a non-racist? Could one be a eugenicist and yet oppose the doctrine of "race hygiene"? Hooton is such an interesting figure because he, more than anyone, stood at the center of established race science during the 1920's and 1930's.

    By 1930, Hooton made it clear he believed something had to be done about what he saw as our increasing lack of biological fitness. “[I]n spite of the infinitesimal quantity of our knowledge [of their genetic bases], we are completely justified in urging that measures be taken to prevent the insane and the mentally defective from reproducing. Segregation and sterilization of the unfit ought to be promoted by scientists and by instructed laymen” (Hooton,1930b:103). But at the same time, he goes on to warn that “we have no data which justify the raising of racial issues as a part of eugenics propaganda. We know nothing at all about inherent superiorities or inferiorities of the several races and the many nationalities. If eugenics is to be made the vehicle of bigoted race prejudice, it must be ditched… To me, eugenics in the United States represents too much ill-considered talk and too little careful scientific research” (Hooton,1930b:103). Those in the eugenics movement in the United States who were in fact displaying “bigoted race prejudice” became role models for German “racial hygienists” before Hitler's ascension in 1933 and admirers afterward, for a while (Kühl,1994).

    Giles is in the end a defender of Hooton, in opposition to recent public presentations (in particular the "Understanding Race" project by the American Anthropological Association) which Giles sees as having tarnished Hooton's scientific reputation.

    For another view of Hooton, Jon Marks returns to blogging: "A Rootin' Tootin' Blog Post". Marks is writing in partial reaction (or addendum) to Giles, accentuating the negative. Marks acknowledges that Hooton was a complicated character -- speaking out against some of the worst instances of scientific racism, but ultimately rooted himself in a typological scheme of human classification that was losing its value.

    Anyway, back to Hooton. His ideas about race, and about human biology generally, certainly weren’t the worst ones around at the time, but that’s faint praise. I think my biggest problem with Hooton, since it’s hard to know exactly what he did believe at any point in time, is that he did not use his position as an authority to confront and repudiate the worst elements of racial science in America. He went after the Germans, which was safe, and although he tried to differentiate his racial science from theirs, he ultimately was not very successful, because his physical anthropology was in fact only subtly different from theirs.

    However, Marks adds a number of quotes and historical cases in which Hooton presents a less sympathetic side. It is clear that if words are actions, Hooton's record is complicated.

    Hooton's racial typological scheme was just as complicated as his position in the history of science. I'm interested in the theory as well as the social impacts of the theory, and this is a great case in the history of science where social change and changes in scientific theories were linked. Like Ptolemaic epicycles, Hooton's classification was an attempt to shoehorn the growing data on human diversity into a theoretical scheme that was losing its value. His typology was full of dozens of "minor races" as variants of the "major" three. Yet the scheme of clinal variation that would come to dominate in postwar anthropology left much unexplained.

    I think the Copernican revolution is in some ways a good analogy -- replacing epicycles with heliocentric orbits was in the long run the correct choice, but circular orbits as predicted by Copernicus did not fit the data as well as the overly complicated Ptolemaic scheme. In astronomy, this problem was solved by Kepler and elliptical orbits. But the transition from the geocentric to heliocentric view wasn't easy, with many heavyweight holdouts for a long time, and hybrid systems like Tycho Brahe's geo-heliocentric model.

    In human biology, clines were indeed more correct as a description of the pattern of variation. As Hooton and his contemporaries began to appreciate, typological races would have to be endlessly subdivided to adequately account for variation. Any typological theory is weighed down by this complexity.

    But the clinal perspective is not as simple as generally presented -- clines of variation in humans are not random, nor equally distributed, and some human populations really have undergone long periods of very low gene flow from others. The advent of genetics in the 1950s promised to make human classification simple -- as simple as blood type frequencies. In fact over time genetics has reinforced the complexity of our history as a polytypic species.

    So Hooton, a representative of the Old Guard as his students began to pursue a new kind of human classification, is tremendously interesting. I recommend Giles' entire article, and will be looking forward to seeing more.
