The Tasmania Effect

by Henry Farrell on August 2, 2010

Charlie Stross has been blogging about “the minimum population”:http://www.antipope.org/charlie/blog-static/2010/07/insufficient-data.html needed to sustain an advanced industrialized civilization (and why he thinks this means no colonization of space etc). This is a topic I have _no expertise on_ beyond a broad interest in the less Sunday-supplement inclined versions of evolutionary anthropology, which have given this question some thought. See, for example, Robert Boyd and Peter Richerson’s account of “the Tasmania effect” (p. 272 of _The Origin and Evolution of Cultures_ ) as excerpted below. While I can’t vouch for this argument myself (and it seems to be based more on modeling than on empirical evidence, which is reasonable when you don’t have as much direct evidence as you would like, but not entirely satisfying), it is interesting and (to me) plausible,. Further, it suggests an additional twist to Charlie’s argument – that because human beings cannot learn _precisely_ what their teachers are trying to convey, you need a larger population to counter for the lossy transmission of useful techniques.

bq. What is less well understood is the extent to which technology is likely a product of large-scale social systems. “Henrich (2004b)”:http://www2.psych.ubc.ca/~henrich/Website/Papers/HenrichAmericanAntiquity2004.pdf has analyzed models of the “Tasmanian Effect.” At the time of European contact, the Tasmanians had the simplest toolkit ever recorded in an extant human society … Archaeological evidence indicates that Tasmanian simplicity resulted from both the gradual loss of items from their own pre-Holocene toolkit and the failure to develop many of the technlogies that subsequently arose only 150km to the north in Australia … Henrich’s analysis indicates that imperfect inference during social learning, rather than stochastic loss due to drift-like effects, is the most likely reason for this loss. This suggests that to maintain an equilibrium toolkit as complex as those of late Pleistocene hunter-gatherers likely required a rather large population of people who interacted fairly freely so that rare, highly skilled performances, spread by selective imitation, could compensate for the routine loss of skills due to imperfect inferences.

A “recent piece of research”:http://ideas.repec.org/p/lec/leecon/09-23.html by British economist James Rockey into people’s misperception of their place on the political spectrum got a certain amount of “gleeful mileage”:http://blogs.telegraph.co.uk/news/edwest/100047245/why-middle-class-lefties-believe-stupid-things-because-their-friends-do/ in the right-wing press, and for predictable reasons. The research claimed that many people mislocate themselves – identifying with the “left” even though they hold opinions that are fairly right-wing. Having worried this over for a few weeks now, my considered view is that whilst the research is flawed at a quite fundamental level, the conclusion might contain some truth. Let’s see if I can express that thinking without contradicting myself!

Jansson’s Illustrated Alice

by John Holbo on July 31, 2010

Speaking of Tove Jansson: when I got home from vacation, a prize awaited me. Just before I left I scored a cheap 1st edition of Jansson’s illustrated Alice In Wonderland on Abebooks. (And – oh look! [UPDATE: you didn’t look quick enough] – there’s another one available for only $38. Which is quite reasonable, compared to the prices for all the other available copies.) Mine is an ex-library copy, of the sort disdained by collectors, particularly where children’s books are concerned. (Nasty things, with their sticky, mauling, foxing fingers! thinks the collector.) But it’s in good shape, and I appreciate how it came complete with an envelope-tucked library card, earnestly autographed by several young ladies – no boys – who I like to think will now go through life with quite un-Tennielish notions of these characters (not that there’s anything wrong with Tenniel, good heavens. But it’s just funny to imagine not being able to imagine the Hatter as looking like anyone but Snufkin) … [click to continue…]

Hot and Cool Jansson & Jazz

by John Holbo on July 30, 2010

Golly, I haven’t posted to a blog for nigh a month. I haven’t actually been off in the wilderness but we’ve been on vacation and I resolved to keep my news and blog engagement to a minimum, while enjoying the great outdoors – Oregon and then New York – just to see how that treats my head. Good, it turns out. Reading several whole books, I started to feel the old attention span growing back.

Best: two short Tove Jansson novels – more or less ‘adult’ novels, at any rate not moomintroll books: The Summer Book and The True Deceiver [amazon]. Lovely stuff. Seasonal and moody and melancholy and not as funny as the moomin books, but funny. Mildly obsessive characters sort of bump into each other as they make painful and pleasurable private ways through the summer or winter. Some moomintypes have turned human – palpable touches of fillyjonkery (fillyjonquerie?), hemulic tidiness, whomperish literality, my-ish determination, etc. Which is interesting to watch. (But that’s not the only reason to read the books.)

And now that I check my Flickr contact updates …

The Library of Congress is serially posting to Flickr what promises to be a huge set of Golden Age jazz photos taken by William Gottlieb. (First link takes you to the easier-to-overview but only just started Flickr stuff. Second, to the complete and text searchable, but less overviewable complete collection.) I like this Cab Calloway. And a nice Django Rheinhardt. Gene Krupa as a zombie? Eh.

Gottlieb released it all into the public domain but some of the images still have publicity and privacy rights issues, apparently.

Political philosophy and the left

by Chris Bertram on July 30, 2010

Part one of a superb interview of Stuart White by Edward Lewis over at the Next Left Project. Meritocracy, luck egalitarianism, status inequality, negative liberty and republican liberty all get some discussion. I particularly liked Stuart’s observation that contemporary politics is keen on the “choice” side of luck egalitarian argument but tends to little or nothing about the correction of brute luck.

The bottom of the barrel, let me scrape it for you

by Kieran Healy on July 29, 2010

I thought that I’d never been asked to join JournoList because, unlike some people around here, I am not a member of the elite liberal-media vanguard. As it turns out, though, I was not asked to join because, truth be told, I am quite a handsome man. I take no pride in this fact, believe me, but was reminded of it when Twitter threw up this piece of genius, which argues that the liberal JouroListers were all pig-ugly losers who had been on “the business end of a fugly stick beat-down”. It brought a tear to my eye, reminiscent as it was of the good old days of blogging, when such arguments were very much to the fore. The real reason I bring this up, though, was to show you a screenshot of the piece:

Who among us has not marveled at DaVinci’s David while strolling through the streets of Venice? It’s one of the many gifts of Western Civilization that a solid conservative education teaches us about.

“Andrea Brandolini”:http://pas.sagepub.com/content/38/2/212.full.pdf

bq. What I really find conspicuous in the comparison of top income shares across rich nations is the similarity of the patterns observed in English-speaking countries as opposed to those found in continental European countries. It is striking that, after a prolonged period of moderate decline, the income share of the richest 1 percent suddenly began to rise in the mid-1980s in the United Kingdom, Canada, Ireland, Australia, and New Zealand as well as in the United States, while it exhibited no upward trend in France, Germany, the Netherlands, Spain, and Switzerland.

bq. The difference between these two groups of countries confirms that market and technological forces cannot be the whole story, but the similarity of trajectories, including the time of the turning point, in the English-speaking countries defies an explanation based only on the national characteristics of the U.S. political process. Hacker and Pierson recognize the potential problem, but play it down by positing that the close interdependence of the markets for top executives can largely account for the common trends in English-speaking economies. Perhaps, but why should interdependence be so much stronger between London and New York than between London and Frankfurt in today’s highly integrated financial markets? Can common language be the only critical factor, or are there more fundamental reasons?

Emulating the trappings of a dictatorship

by Henry Farrell on July 28, 2010

Jim Lindgren, who has apparently rowed back on “his promise to reveal ‘a lot more’ about Journolist over the next few days”:http://volokh.com/2010/07/22/obama-campaign-advisor-participated-on-journolist/, “explains it all”:http://volokh.com/2010/07/27/michelle-obama-asks-me-to-sign-president-obamas-birthday-card/.

Update: Anderson, a frequent commenter at the Volokh Conspiracy, has created a “shadow blog”:http://jimlindgrensucks.blogspot.com/ so that people can comment on Jim Lindgren’s posts if they want to (Lindgren usually turns off comments himself).

What Produced the Inequality Boom?

by Henry Farrell on July 28, 2010

Riffing off John’s “post of a few days ago”:https://crookedtimber.org/2010/07/25/who-gained-from-the-inequality-boom/, the most recent issue of Politics and Society (which, as I noted before, “has free access”:http://pas.sagepub.com/content/current for the next few months” ) has a pretty interesting debate on this topic. There are four contender. One of these – the standard technology-leading-to-inequality-story – is not discussed at any length in _Politics and Society_, but this accont doesn’t in any event tell us why there has been substantial variation in the impact of technology on different industrialized democracies, and hence requires at the least an account of intermediating forces.

Red Plenty

by Henry Farrell on July 27, 2010

I get far more free books from publishers than I can read, let alone write about (a source of persistent, if mild guilt). And this book I haven’t read yet, since I only got it this morning. But I have been _wanting_ to read it ever since I read “Ken MacLeod’s brief account”:http://kenmacleod.blogspot.com/2010/05/red-plenty.html ; how it is that the publicity department of Faber and Faber discovered this entirely unexpressed desire of mine, I don’t know. Ken:

bq. It’s a fictionalised account, or a non-fiction novel, about the project in the early 1960s to use computers to plan the Soviet economy. A key figure is the genius Kantorovich, who invented the mathematical technique of linear programming in 1938. (We follow his mind as the idea dawns on him, on a tram.) He and other real characters such as Kosygin and Khrushchev mingle with fictitious characters – some based on real people, some not, but all convincing. It’s a bit like reading a novel by Kim Stanley Robinson, Neal Stephenson, or Ursula Le Guin – or maybe a mashup of all them; full of arguments between passionate and intelligent people, diverting (in both senses) infodumps, and all about something that actually happened – and, more significantly, about something that didn’t happen, and why it didn’t.

Worth noting that the cover is far spiffier looking than a compressed jpeg can convey. Worth also noting that MacLeod’s own recent novel, “The Restoration Game”:http://www.ft.com/cms/s/2/3a11008e-9069-11df-ad26-00144feab49a.html looks like a lot of fun; since it doesn’t appear to have a US publisher, I’m waiting till I get to Ireland next month to pick it up.

Hugo Awards II

by Henry Farrell on July 26, 2010

One of the nominees this year (for best related work) is Farah Mendlesohn’s “The Inter-Galactic Playground: A Critical Study of Children’s and Teens’ Science Fiction”:http://www.amazon.com/gp/product/0786435038?ie=UTF8&tag=henryfarrell-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=0786435038. I haven’t read the other contenders, but wanted to do a quick write up. It’s a fun book, with an argument that both contributes to genre studies and sets out Mendlesohn’s own position on the kind of books that sf writers for younger readers _ought_ to be writing.

“Martin Wolf in the FT today”:http://blogs.ft.com/martin-wolf-exchange/2010/07/25/the-political-genius-of-supply-side-economics/

bq. Whatever the rhetoric, I have long considered the US the advanced world’s most Keynesian nation – the one in which government (including the Federal Reserve) is most expected to generate healthy demand at all times, largely because jobs are, in the US, the only safety net for those of working age.

I’m not sure I agree (or more precisely: your level of agreement with this statement will depend on exactly how you want to define Keynesianism) – but it’s worth pointing out that this is at the least quite consonant with Tyler Cowen’s “arguments about Germany”:http://www.nytimes.com/2010/07/18/business/18view.html?_r=1&scp=1&sq=tyler%20cowen&st=cse. On the one hand, this intellectual convergence could be taken as suggesting that Tyler’s case suggests that German-style social democracy works better than US style Keynesianism (an argument which I _think_ Tyler agrees with, at least with respect to Germans). On the other, it could be taken as suggesting that despite Wolf’s frequent minatory statements about the external consequences of the German model, he believes that it works better in relative terms than US-style Keynesianism in providing _internal_ economic security and political stability. Certainly, he is quite skeptical about the prospects of the US economic system given Republicans’ role as a blocking minority and perhaps majority in the near future (his most provocative suggestion is that Republicans are a perverted species of Keynesians).

Who has gained from the inequality boom?

by John Q on July 25, 2010

A question that comes up at CT quite a bit is: who has benefited from the massive increase in US income inequality over recent decades. I finally got around to chasing down Congressional Budget Office data (derived from tax records for the period 1979 to 2005), and the answer, in short is:
* The top 1 per cent roughly doubled their share of both pre-tax income (9 per cent to 18 percent) and after-tax income (7.5 per cent to 15 per cent)
* The rest of the top 10 per cent slightly increased their share (from about 20 to about 22 per cent)
* The next 10 per cent held their share (about 15 percent)
* The remaining 80 per cent of households saw their share drop (from 58 per cent to 48 per cent of post-tax income, with the biggest drops coming at the bottom. The bottom 40 per cent of households now get a smaller share of post tax income (14 per cent, down from 19) than the top 1 per cent.

Live on Video

by John Q on July 25, 2010

After the usual hassles, UQ School of Economics finally has its own videoconference facility, an IP-based Tandberg system, which should (fingers crossed) be interoperable with other standards-based systems. I just did my first conference, and it worked very well. Unfortunately, we are still waiting for an upgrade that will let me run a presentation at the same time as appearing on video. But I’m confident of ultimate success, so I’m now announcing that I’m available to give seminars and talks on a wide range of topics to anyone (subject to time and timezone constraints!) who would like to organise a videoconference. Email me j.quiggin at uq.edu.au if you are interested.
