Teaching is a repeated game

John Sides and Inside Higher Ed today discuss a rather, er, innovative approach to grading classroom assessment (gotta go with the Newspeak term)—essentially, rewarding effort, consistent participation, and de minimis competence, and having students be the judge of said de minimis competence.

I have a couple of reactions: first, while this might work with a student body as generally overachieving as Duke’s, I shudder to think what would happen if I handed over control of my gradebook to the median student in my current general education summer classes, who can be best characterized as mildly disinterested in the material at hand. (I can’t say I blame them on this score, either. I hardly was thrilled by gen ed in my undergrad days, even if some of the classes turned out more interesting than I had expected.)

The second problem is located by a professor commenting at IHE who tried something very similar and found it did not survive repeated contact with the student body at my graduate alma mater:

I tried this for several years in the mid-nineties. I found it worked wonderfully—the first time I tried it. The students worked much harder than they ever would have for a grade, and enjoyed the learning experience more, and told me later it was the best class they took in college. But the next semester it worked worse, and it kept working worse and worse for the three or so years I used the system. I kept tweaking it, trying to find a way to restore its original success; but no luck.

I finally realized what was going on: word was out that my class was an “easy A,” and it was attracting all the laziest students. I invariably had one or two motivated students who were there for the novel learning experience, and then a whole slew of slackers who wanted to coast. ...

My project was an overidealistic one, I finally realized (and, gritting my teeth, went back to more traditional grading): I wanted to RELEASE my students’ “natural” love of learning from the bonds in which they had been encased by fourteen or fifteen years of grade-slavery. I love to learn; hence, a love of learning is “natural”; hence, grade-based opportunism is artificial; a conditioned jail; hence, my students need to be liberated from their jails. I realized at some point that my project was actually one of reconditioning my students to be more like me—and that, while it did work in some cases, not only was a semester not a long enough reconditioning period, but the project itself was suspect.

There are some more positive reactions, including one quoted by the author of the IHE piece that… well, you be the judge:

I’ve done something like this with my big undergrad class, ‘Intersections: Race, Gender & Sexuality in US History,’ for years now. They do all the work, at a ‘good faith’ level of quality (earning a check from their TA), show up on time to all classes and participate in discussion sections—they get an A. Grades scale down from there. The greatest thing about it is that many students without previous educational privilege love it and often do extremely well when not being judged in the usual way—reading a book a week, writing response papers every week, and ultimately participating at grad student level. Entitled students who try to skate by on a good prose style do not like it at all.

Once one starts using terms like “students with[] previous educational privilege” to refer to students who complete the required readings, who have bothered to learn the rudiments of writing clear, coherent prose, and who exceed the bare minimum standards one’s TA is enforcing, one may have lost the plot entirely.

Indeed, it is hard not to suspect that the true motivation here lies less in “liberating” students from the yoke of grades (or at least bad grades) than it does in liberating faculty from their own responsibilities to sit in judgment of their students’ work, with all of the potential hard feelings that said responsibility entails. I suppose this is the natural consequence of faculty already abdicating their responsibilities to conduct classes small enough to interact with students—enter the “discussion section,” and your cadre of TAs brought in with little prospect of future employment beyond the fast food industry to keep the students happy while you blog your New Age theories of pedagogy do research. Once you’ve collectively decided you no longer give a damn about teaching, I suppose it’s a very short walk to ceasing to give a shit about assessing student learning either.

swift boat, v.t.

How exactly are Barack Obama’s problems with Jeremiah Wright a swift boating? I like Obama about as much as your average Republican-leaning academic blogger with libertarian leanings, but it’s hard to see that there’s much that’s unfair about attacking a political candidate who willingly associates himself on a weekly basis with a pastor who frequently crosses the line that separates legitimate critiques of American race relations and delusional paranoia.

James Joyner made much the same point Thursday, in reference to a YouTube video that’s been making the rounds and the basis for Sullivan’s defense of his favored candidate:

Does the video play on the fears that some whites have about angry black men? Sure. Mostly, though, it seeks to undermine Obama’s portrait of himself as mainstream. It’s more than a little unfair but that’s the nature of these mashups. It’s no different than the various ads of one candidate morphing into an unpopular politician that we’ve seen over the years. And it’s frankly much tamer than the infamous 1964 ad that implied Barry Goldwater would get us annihilated in a nuclear war or the 2000 NAACP ad featuring the daughter of James Byrd stating that “when Governor George W. Bush refused to support hate-crime legislation, it was like my father was killed all over again.” Goodness, I’m not sure it’s even as insidious as the “3 a.m.” ad that the Clinton campaign ran to such good effect last month.

All that said, if the McCain campaign wants to shit-can some guy on their payroll who shared that video on Twitter, that’s their prerogative; any campaign that can’t keep their employees on-message is doomed to controversy—ask Amanda Marcotte, or for that matter John “Two Americas But Stuck In Third Place” Edwards.

Pigeonholing

Megan asks:

How did I end up on the Libertarian circuit anyway? I am quite the bleeding heart; I give change to homeless people and play team sports and volunteer in a community garden and shit. It’s like I’ve fallen in with a bad crowd, just ‘cause they’re all funny and cool. Marginal Revolution is totally a gateway drug.

I’m not sure any of those things would qualify or disqualify anyone from being a libertarian (or even a Libertarian), since none of them have to do with the use of the government’s monopoly on the legitimate use of force to coerce certain individual behavior. No libertarian I’m aware of would forbid† Megan from giving change to homeless people, playing team sports, or volunteering in community gardens; nor would any* make her do any of those things.

† Hardcore Objectivists would probably make fun of her for doing some of these things, but one need not subscribe to Objectivist beliefs to be a libertarian. Thank God.
* Well, except a few liberals who like to call themselves “libertarian” because they’re for some unfathomable reason embarrassed to be known as liberals, like Bill Maher. But that’s a whole other kettle of fish.

Nifong and the paper trail

I’ve generally lost interest in the whole Duke lacrosse imbroglio, but KC Johnson notes some very interesting developments in the case that reinforce my prior belief that Durham DA Mike Nifong is, as the kids say, “completely full of shit.”

Why Gaeta is a Cylon

Duke alum Allison Clarke has seven good reasons why you should believe that Felix Gaeta is a Cylon. I’m still not entirely convinced that Ron Moore wants to go that way, but if he does the necessary clues have certainly accumulated over time.

My case will go on and on

Righteous Townie DA Mike Nifong is channeling Celine Dion (or perhaps Don Quixote) today, promising that “this case is not going away” at a forum on the rape allegations this morning at NC Central University that he parachuted into at the last minute (see also WRAL). The Herald-Sun account shares the following gems from Nifong:

Nifong said further DNA tests are being conducted and that the woman making the allegations has identified at least one lacrosse player as an attacker.

“I hope you will understand by my presence here this morning that the case is not going away,” Nifong said. DNA results can be helpful, but DNA evidence is absent in 75 to 80 percent of cases, he said. They also can clear the innocent, which remains an important consideration, after the March 13 team party at which team members admit hiring two exotic dancers. One of them told police three men took her into a bathroom of the house at 610 N. Buchanan Blvd., where they beat and raped her.

“Until we identify all three of those people, that means some of these young men are going to be walking around under a cloud,” Nifong said.

But, he said later, in response to a comment in a question-and-answer that police and prosecutors arrest black suspects more quickly than whites in such cases: “There was no identification of any member of the lacrosse team until last week” and that identification of an attacker in this case will be a question for a jury to decide.

“There was no identification of any member of the lacrosse team until last week.” I am beyond speechless. Either Nifong is letting a guy who he knows has been identified as a rapist just run around free (way to ensure the safety of the community!), or he’s completely full of shit.

The good news is that in three weeks this idiot will be out of our collective misery, when the voters of Durham County run his ass out of town on a rail. The bad news is that until then we get three more weeks of this idiot in our collective misery.

Duke under siege, day eight: it's all about the booze (and the News)

Today’s theme is alcohol; UD points to Allison Clarke’s lengthy post on the culture of drinking at Duke, while Paul Bonner of the Herald-Sun catches up with William Willimon, the former dean of Duke Chapel who wrote a report on Duke’s drinking culture in the early 1990s.

Elsewhere in the legacy media, Newsday reports that attorneys for the lacrosse team members plan to release the DNA test results, even if Righteous Townie AD Mike Nifong doesn’t, the New York Times reports that the alleged victim has joined the lacrosse captains in self-imposed exile from their homes due to the media attention, and Filip Bondy whines in the New York Daily News that he can’t get any juicy quotes from the women’s basketball team, who presumably have better things to do than opine about the rape allegations to ninth-tier sports reporters who normally don’t give a shit about women’s college basketball (or lacrosse, for that matter).

Since Nifong is away from the cameras much of this week, I don’t expect any major developments… but I’ll keep an eye on things nonetheless.

NCAA tournament thoughts

A couple of disconnected thoughts about the NCAA basketball tournament thus far:

  • If the NCAA wants us to treat the play-in game as part of the “real” tournament, they’re going to have to do better than producing “Opening Round” bunting for the scorer’s table. At the very least, they need to call ESPN and tell them that they’re not allowed to do bush-league phone-in blowout material over the game action. More realistically, the “opening round” needs to be a real round, with four play-in games—one for each region. And the games need to be played in front of a crowd that gives a shit about the outcome, which you’re not generally going to find in Dayton, Ohio.
  • I’d never accuse the selection committee of showing favoritism toward generating good product, but it’s a mighty convenient coincidence that a lot of good, name-brand major conference teams are free to play deep into the now NCAA-owned-and-operated NIT rather than facing a second-round “big dance” exit against like likes of UConn or Duke.

My brackets, incidentally, are pretty boring; I’m not at all sold on Gonzaga or Tennessee doing much in the tourney. I picked Duke to win it all, over North Carolina (in my Yahoo! bracket) and Boston College (in my ESPN bracket)—I think otherwise the two brackets are identical.

The Swedes are coming

Today’s Duke Chronicle reports on the results of Ted Roof’s latest efforts to dupe impressionable 18-year-olds into coming to Durham to play a sport other than basketball rebuild Duke’s football program on the recruiting trail, said efforts yielding (of all things) a pair of Swedes. As in kids from Sweden. I shit you not. I didn’t realize Malmö was such a hotbed of gridiron talent…

Meanwhile the best football player on campus is still pursuing the revenue sport Duke doesn’t suck at. Go figure.

Hiring decisions in political science

An interesting piece in this quarter’s issue of PS (sadly not online), by Daniel Fuerstman and Stephan Levartu of UW-Madison, looks at the factors that departments consider when hiring new faculty. Notably, everyone seems to care about a nebulous quality called “fit,” teaching is #2 at everywhere except national universities, and nobody gives a shit about conference presentations and awards. Perhaps most interesting: letters rank highly at all types of institutions, despite the common perception that recommendation letters are inherently undifferentiated and thus information-free.

All Dean, all the time

(I figure if Eric Muller can do it, so can I…)

Howard Dean’s upcoming whirlwind tour of flyover country attracts some pub from the AP’s Emily Wagster Pettus, last seen here at Signifying Nothing looking for state legislators dumb enough to show at a Council of Conservative Citizens function (in the end, none were). Let’s play “spot the inconsistency in Howard’s message”:

Dean said today Democrats need to appeal to working-class whites and blacks in the South.

He will speak at a $75-a-ticket Democratic dinner at 7 p.m. Tuesday at the Clarion Hotel in Jackson.

Way to broaden the party’s base, Howie!

I’m not unsympathetic to Dean’s arguments, although I have to say that on the issues the Mississippi Democrats are “right” on—things like civil liberties, abortion rights, and even (gasp) raising taxes to fix this state’s massively clusterf-cked budget*—their legislative caucus doesn’t have the cojones to stand up and be counted. Instead, they waste everyone’s time with idiotic Republican-lite shit like cracking down on sales of cold medicine, and slather on a good helping of smoke-filled room politics† just to make it more embarrassing. Not to mention that back in 2001 you couldn’t find a white Mississippi Democrat without a foot in the grave—William Winter doesn’t count, so you don’t get to trot him out—who lifted a finger to get rid of the Southern Cross on the flag.

In short: wanna sell me on the Mississippi Democratic Party? Start acting like Democrats who have gerrymandered yourselves into safe seats for life, instead of Republicans who have gerrymandered yourselves into safe seats for life, because in a contest between real Republicans and fake ones I’ll take the real ones (see Musgrove, Ronnie). I’ll even let you keep Bennie Thompson, just so long as you promise to never put me in his district.

This is my entry in today’s OTB Traffic Jam.

Arianna "Shit for brains" Huffington

Apparently, in Arianna’s world, a guy that creates a company from scratch in his dorm room—enriching millions in the process—is a demon when it becomes economical to offshore 3000 jobs to India:

MICHAEL “DUDE, YOU GOT OUTSOURCED!” DELL

Name: Michael S. Dell
Company: Dell Computers
Title: Chairman and Former CEO (Chairman and CEO until July, 2004)
Crime Against America: Dell’s Bangalore and Hyderabad, India, facilities employ close to 3,000 people.
Partner in Crime: Dell has contributed $3,000 to the Bush campaign in 2003 and 2004, plus an additional $25,000 the Republican National Committee, and $10,000 to the National Republican Congressional Committee. Dell CFO James M. Schneider is a $25,000 contributor to the RNC.

Even more unpardonable: he donated to Republicans. Arianna supposedly has an economics degree, though it appears that anything she learned has long since disappeared. She still has mastery of the Populism 101 material, though.

The mind of the undecided voter

Christopher Hayes has an interesting article at The New Republic on undecided voters whom he spoke to in Wisconsin, while campaigning for Kerry during the final seven weeks before the election. His anecdata range from the funny
One man told me he voted for Bush in 2000 because he thought that with Cheney, an oilman, on the ticket, the administration would finally be able to make us independent from foreign oil. A colleague spoke to a voter who had been a big Howard Dean fan, but had switched to supporting Bush after Dean lost the nomination. After half an hour in the man's house, she still couldn't make sense of his decision. Then there was the woman who called our office a few weeks before the election to tell us that though she had signed up to volunteer for Kerry she had now decided to back Bush. Why? Because the president supported stem cell research.
to the truly sad
I had one conversation with an undecided, sixtyish, white voter whose wife was voting for Kerry. When I mentioned the "mess in Iraq" he lit up. "We should have gone through Iraq like shit through tinfoil," he said, leaning hard on the railing of his porch. As I tried to make sense of the mental image this evoked, he continued: "I mean we should have dominated the place; that's the only thing these people understand. ... Teaching democracy to Arabs is like teaching the alphabet to rats."
to the insightful
Undecided voters, as everyone knows, have a deep skepticism about the ability of politicians to keep their promises and solve problems. So the staggering incompetence and irresponsibility of the Bush administration and the demonstrably poor state of world affairs seemed to serve not as indictments of Bush in particular, but rather of politicians in general. Kerry, by mere dint of being on the ballot, was somehow tainted by Bush's failures as badly as Bush was.
Unfogged.)

Eugenics advocate runs for Congress

Via Abiola Lapite, I learned that this pathetic racist piece of shit is running for the Republican Congressional nomination in Tennessee’s 8th district, which includes part of Shelby County (although not Memphis).

Unfortunately, he’s the only one on the ballot. According to this AP story, Tennessee Republican leaders didn’t bother fielding a candidate, since the 8th district is considered a safe Democratic seat for Rep. John Tanner.

The polls will be closing in about ten minutes. Nevertheless, I’d like to wish good luck to Dennis Bertrand, who is running as a write-in candidate.

UPDATE: The racist piece of shit is in the lead, 4907 to 416, with 48% of precincts reporting. Sigh.

UPDATE 2: The racist has won. This has not been a good week for race relations in western Tennessee.

This is what Deliberation Day would look like: hell

Marybeth links a Joel Klein piece on the fun and excitement that is the Iowa caucuses. Classic quotes:

To explain how it all works, Iowa Secretary of State Chet Culver is going around the state holding practice caucuses. At his workshop last Tuesday at the library in Clive, a suburb seven miles west of Des Moines, about 50 people showed up, several of them young enough to be my parents. Most of these folks already knew how caucuses work and just wanted a refresher course. Clive needs to get itself a bowling alley.

As Culver, 37, a former history teacher, began with an hour-long PowerPoint presentation on the history of the caucus going back to 1846, a sign-language interpreter flashed signs — even though not a single person in the room was deaf. It hit me about 15 minutes into the speech that the sign-language guy must have realized no one there was deaf, but by that time it was too embarrassing to just stop. So he kept going, his bravery a further testimony to the lengths Iowans go through just to get David Broder to visit.

At least Bob Putnam would approve!

For the second hour, Culver had the audience stage a fake caucus. It turns out the Republican caucus is really simple. They pass around ballots, count them and go home to watch Everybody Loves Raymond while the Democrats are still reading their rules. I predict the state will eventually be 100% Republican.

Once all the candidates have at least 15%, a formula Culver describes as “needing a Ph.D. in math to understand” is used to determine how many delegates each candidate gets. The percentage of delegates each candidate gets is the number reported in the media. Then the media, for reasons that are unclear, pretend that has something to do with whom the country wants to be President.

Yes, this is exactly the sort of shit Ackerman and Fishkin want to foist on America. Thanks—but no thanks.

Cussin' in the classroom

Will Baude is documenting Dan Drezner’s use of profanity in the classroom. I think I’ve used “pissed off” and variants of “shit” in lectures, but never anything stronger. On the other hand, I’m sure my students have used far worse terms in reference to me…

Pete Rose

I’m a bit late to the story of Pete Rose admitting he bet on baseball—a story that was actually supposed to be embargoed until his appearance on ABC’s Primetime Live, but no matter (earlier reactions include John Cole’s and Michele’s; everyone in my blogroll who has an RSS feed and had something to say about it is listed here) . I think Larry Ribstein’s reaction one of the more interesting, though I don’t think it gets to the heart of the problem with stated betting on baseball.

That Rose bet on games involving the Reds is the big “no-no” issue; if he’d simply bet on other teams, he’d have received a one year suspension. The key question is what is the harm to Baseball from Rose’s bets?—and, by Baseball, I mean the institution that everyone has been saying Rose sullied. Since nobody claims he actually bet against the Reds, it’s hard to charge him with throwing games; he may have had an extra incentive to win in games he wagered on, but that isn’t throwing a game, and unlike other sports baseball betting is normally on the “money line”—you pick straight-up, not against a point spread—so “point shaving” (or “running up the score“) isn’t an issue. (You can also bet other sports, like football, on the money line, but that isn’t very popular.) Rose’s interest as a bettor coincided with his unbiased interest as a manager.

Now, some have argued that because Rose didn’t bet on every single game, and that he apparently got inside information from other managers (including those in the AL—the Reds are an NL team, and before interleague play intelligence on AL teams was pretty useless for NL managers), his behavior is somehow corrupting to Baseball. Because Rose didn’t bet on all games involving the Reds, the argument is that bookies knew that the Reds were less likely to win the game. Even if that’s true, it’s hard to see how Baseball is harmed. The victim is whoever was on the losing side of the bets lodged by Rose’s bookies because of the informational advantage they had—unless Baseball was betting on games, they weren’t harmed at all. Similarly, Rose’s intelligence on other teams only harmed other bettors—not Baseball. And, ultimately, since virtually everyone who was involved was violating numerous state and federal laws against sports wagering—the harm was to people who were already engaging in illegal conduct. If a thief breaks into a drug dealer’s house and steals his TV, the thief’s criminal act doesn’t absolve the dealer for buying home electronics from the proceeds of his own illegal act.

Now, there are other reasonable arguments against Rose’s betting: that it potentially created the appearance of corruption: for example, that it placed him in a position where he might be able to throw games to have his gambling debts reduced. But there doesn’t seem to be evidence that Rose threw games—and, in general I find “appearance of corruption” arguments specious. You can also argue that Rose harmed Baseball as an institution by denying the allegations for 14 years and impugning the credibility of his accusers and other opponents, including then-NBC reporter Jim Gray (who now spends his time about as far up Kobe Bryant’s ass as Ahmad Rashad was up Michael Jordan’s). And Rose’s frequent appearances in Cooperstown, New York haven’t exactly endeared him to the MLB brass. But Rose’s betting, alone, apparently had no ill effects on Baseball.

Update: John Jenkins disagrees with my assessment, as does David Wright via email; both raise essentially the same point (I'll quote John’s post):

Rose's gambling on the Reds changed the way Rose managed games. Baseball has a 162-game season. When Rose had money riding on a game, he would obviously be managing to win that game at the expense of future games. Suppose Rose was clinging to a one-run game going into the ninth and his closer had pitched the last three days straight and his arm was sore. Rose might pitch the guy to win that game because he had money on it, and then cost the team 3 games over the next 2 weeks that they could have won if that pitcher could have rested that day.

I do agree that having money riding on the game might pervert Rose’s incentive structure—and my overlooking that fact may go to show you how much I really care about baseball as a game. On the other hand, Rose’s mediocrity as a manager is such that he might have made decisions that were weak over the long term anyway, even without the monetary incentive to do so.

Another update: Brian of Redbird Nation makes a compelling case for a shorter-than-lifetime ban for Pete Rose.

Clarkbot fodder

Like Martin Devon of Patio Pundit, I just wasted half an hour of my life in a hotel room watching Wesley Clark on MSNBC’s Hardball. Martin writes:

I’m listening to Wes Clark on Hardball… and he makes Howard Dean look good. Say what you will about but Dean but he says what he means and he means what he says. With Wes Clark you get the sense that he’s just making shit up. Right now he’s talking about how he would have caught Osama by now, and how he wouldn’t have gone into Iraq. As most of you know, Clark’s early pronouncements weren’t nearly so clear. I’m sorry—he just sounds like an opportunist.

I’ve never been a big Wes Clark fan, even back when I thought that he was a Republican. You know how Dems knock Joe Lieberman as “Bush-lite“? Clark is “Dean-lite.” I don’t see why Clark as any more electable than Dean. Clark has military experience, but that isn’t as good as Dean’s experience as a governor. And Clark is so darn whiny—fingernails on chalkboard.

I particularly enjoyed the moment where Clark, in response to a question from Matthews about what sanction would have been appropriate for Bill Clinton (who quite clearly committed perjury, even if there’s a legitimate argument, that I’m not unsympathetic to, that he never should have been in a situation where he would commit it), launched into a two-minute stump speech that was completely nonresponsive to the question.

Also amusing was Clark’s analysis of the policy formation process of the Bush administration, which seemed to be cribbed directly from a Paul Krugman column (although spiced up with numerous references to nebulous “sources” that Clark is apparently privy to). And I’d love to hear how Clark would have caught Osama bin Laden by now; something tells me he wouldn’t have been hanging out with the Special Ops guys doing the dirty work in the theatre, and the 4th Infantry isn’t interchangeable with the Green Berets—so even if most of the army were stateside instead of patrolling Iraq, I doubt it would make much difference.

Clark also kept going on about his foreign policy gravitas relative to that of George W. Bush; said gravitas was apparently based on (a) being in Europe when the Europeans were rolling their eyes at the Lewinsky scandal and (b) obeying the orders of his civilian masters who had gravitas of their own. I say “apparently,” because he assumed the audience would believe he had foreign policy gravitas on the basis of alleging it alone.

I have to agree with Martin—Clark is “Dean Lite.” Crank up the toaster oven on this guy…

Adesnik responds; didn't know there was Kool-Aid

David Adesnik has a response to the critiques of his earlier posts at OxBlog and the Volokh Conspiracy. He first notes that he’s just as annoyed by new data sets as by old ones:

Actually, I’m far more frustrated by the new data sets than the rehashing of the old ones. Just three days ago I was at a presentation in which a colleague described the data set she assembled on over 120 civil wars that have taken place since 1945. Since Latin America is the region I know best, I pulled the Latin American cases out of the data to set look at them.

What I found was that a very large proportion of the cases were “coded” in a misleading or flat-out wrong manner. Why? Because no one can study 120 civil wars. But pressure to come up with data sets leads scholars to do this anyway and do it poorly. Of course, since their work is evaluated mostly by other scholars who lack the historical knowledge to criticize their work, they get away with it. And so the academic merry-go-round spins merrily along.

That’s a fair and reasonable critique—of that particular dataset. There’s always a tradeoff between parsimony on the one hand and depth on the other. You can collect data on 120 civil wars, and try to explain with parsimony why—in general—civil wars occur, or you can soak and poke in one civil war and try to figure out all the myriad causes for that particular one. Each has its pitfalls; figuring out why Cambodia had a civil war in 1970 (my years are probably off, me not being an IR scholar) through a “soak and poke” really doesn’t help explain why Pakistan had one in 1973. On the other hand, oversimplifying the causes can be problematic too.

But that strikes me as more of a coding problem in a particular dataset than a problem endemic to social science research; ultimately, you have to simplify the real world to make scientific explanations of it. And this isn’t a problem unique to “soft” sciences like political science: physicists don’t really think light is composed of photons that are both a particle and a wave (for example), but the only way for humans to currently understand light is to model it that way, and chemists don’t think that nuclei are indivisible (but, for their purposes 99.9% of the time, they might as well be).

David does take me to task for my admittedly flip remark that Hamas was comparable to the Sierra Club:

With apologies to Chris, his comment summarizes everything that is wrong with political science. Who but a political scientist could think that ideology is not a good explanation for the differences between the Sierra Club and Hamas?

Both groups have fairly revolutionary ideologies, yet they pursue their ends through different means. The Sierra Club operates in an environment where at least some of its goals can be accomplished from within the existing political system, while Hamas’ goal is the obliteration of the existing political system in Israel and the Palestinian territories. One need not resort to ideology to see that the Sierra Club doesn’t need to engage in violence to pursue its goals while it’s pretty clear that for Hamas to produce revolutionary change in the former Palestinian mandate, it does.

That the goal has something to do with Hamas’ ideology is rather beside the point; they can’t accomplish it without obliterating the Israeli state through violent action. The Sierra Club, on the other hand, has a sympathetic political party, a regulatory agency whose civil service employees (if not its politically-appointed overseers) share its goals, and other sources of active support that mean that they can achieve their goal of reducing pollution and other environmental impacts without resorting to violence. Ideology may define the goal, but the goal itself will be pursued through means that are shaped by the political environment.

Of course, in some cases, ideology may affect the means chosen. But a theory of how Osama Bin Laden operates isn’t very generalizable; it only explains how Bin Laden behaves, without explaining how ETA, the Tamil Tigers, or the Real IRA operate. That’s the tradeoff—you can spend a lot of time trying to explain how one actor will behave, and nail that, or you can spend a lot of time explaining how multiple actors will behave, and maybe get close. Maybe Bin Laden deserves case study attention. But most political actors don’t; they’re frankly not that interesting.

For example, in-depth case study of how my neighbor across the street makes his voting decisions tells me next to nothing about how my next-door neighbors vote, much less how people vote in general. My resources are probably better spent trying to explain how most people vote from large-scale survey data, and getting close, rather than studying one person so I can predict precisely how he’ll vote in 2032.

Around Harvard, all one hears is that incorporating statistics into one’s work significantly increases one’s marketability (and I don’t just mean at the p<.05 level—we’re talking p<.01 on a one-tailed test.)

I will grant that the use of statistics—or more accurately, the demonstrated ability to use statistics—helps the marketability of political scientists. For one thing, this is because of hiring practices in political science—your primary or major field defines the sort of job you will get. Unless you are looking for a job at a small liberal arts college, no school that is hiring in IR will care if your second (minor) field is comparative, theory, or American, since you’ll never teach or do research in those fields. The exception is in political methodology: you can get a job in methods with a substantive major and a minor in methods. The downside (if you don’t like methods) is that you will be expected to teach methods. The upside is that you aren’t tied to a particular substantive field.

More to the point, in some fields it is difficult to do meaningful research without statistics. In mass political behavior and political psychology—my areas of substantive research—at least a modicum of statistical knowledge is de rigeur. Which brings me to Dan’s point:

I’d argue that the greater danger is the proliferation of sophisticated regression analysis software like STATA to people who don’t have the faintest friggin’ clue whether their econometric model corresponds to their theoretical model.

For every political scientist that knows what the hell they’re doing with statistics, there are at least two who think typing logit depvar ind1 ind2 ind3 at a Stata prompt is the be-all and end-all of statistical analysis. Frankly, a lot of the stats you see in top-flight journals are flaming crap—among the sins: misspecified models, attempts to make inferences that aren’t supported by the actual econometric model, acceptance of key hypotheses based on marginally significant p values, use of absurdly small samples, failure to engage in any post-estimation diagnostics. And, of course, “people who don’t have the faintest friggin’ clue whether their econometric model corresponds to their theoretical model.” Several thousand political scientists receive Ph.D.’s a year in the United States, and I doubt 20% of them have more than two graduate courses in quantitative research methods—yet an appreciable percentage of the 80% will pass themselves off as being quantitatively competent, which unless they went to a Top 20 institution, they’re almost certainly not.

David then trots out the flawed “APSR is full of quant shit” study, which conflates empirical quantitative research with positive political theory (game theory and other “rat choice” pursuits), which, as I’ve pointed out here before, are completely different beasts. Of course, the study relies on statistics (apparently, they’re only valid when making inferences about our own discipline), but let’s put that aside for the moment. The result of all this posturing is our new journal, Perspectives on Politics. Just in case our discipline wasn’t generating enough landfill material…

He then turns back to the civil war dataset his colleague is assembling:

Take, for example, the flaws in the civil war data set mentioned above. I’m hardly a Latin America specialist, but even some knowledge of the region’s history made it apparent that the data set was flawed. If political scientists had greater expertise in a given region, they would appreciate just how often in-depth study is necessary to get even the basic facts right. Thus, when putting together a global data set, no political scientist would even consider coding the data before consulting colleagues who are experts in the relevant regional subfields.

Undoubtably, this particular political scientist should have consulted with colleagues. What David seems to fail to understand is that she did: that is why your colleague presented this research to you and your fellow graduate students, to get feedback! Everything political scientists do, outside of job talks and their actual publications, is an effort to get feedback on what they’re doing, so as to improve it. This isn’t undergraduate political science, where you are expected to sit still and soak in the brilliance of your betters while trying not to drool or snore. You’re now a grad student, expected to contribute to the body of knowledge that we’ve been assembling—that’s the entire point of the exercise, even if it gets lost in the shuffle of “publish or perish” and the conference circuit.

And one way to do that is to say, “Yo, I think you have some coding errors here!” If this political scientist is worth her salt, instead of treating you like a snot nosed twit, she’ll say, “Gee, thanks for pointing out that the Colombian civil war had N participants instead of M” or “Cuba’s civil war was a Soviet-supported insurgency, not a indigenous movement? Thanks!” (Again, these are hypotheticals; I’m not an expert on Latin American history.)

As for the lag time in Pape’s piece, well that’s the peril of how the publication process works. If it’s anything like any other academic paper, it’s been through various iterations over several years; you don’t simply wake up one morning, write a journal article, and send it off to Bill Jacoby or Jennifer Hochschild. At least, not if you don’t want them to say nasty things about you to your colleagues. Anyway, you can fault the publication process to a point, but I think it’s a safe bet that Pape’s thesis predates 9/11, and that people were aware of it before his APSR piece hit the presses.

9/11/03

I think Michele and Dean have it covered.

Me? I’m going to try to do a bunch of things that would piss Osama off. That is, if he wasn’t worm food already (even those bozos in Lebanon who kidnapped hostages back in the 80s knew how to get newspapers to prove the video was recent). Among them:

  • Go to work.
  • Eat some pork products.
  • Watch some college football.
  • Work on my dissertation.
  • Live.

One thing I won’t be doing: this:

A vigil, sponsored by the UM Activist Coalition, will also be at 6:15 p.m. on the porch of the Croft Institute for International Studies building.

“It will mostly be a silent-type vigil,” Greg Johnson, member of the coalition and blues curator, said. “It's just in honor of all those who died on Sept. 11 and all those who died in resulting policies that have occurred.” [emphasis mine]

Following the vigil, a panel discussion, co-hosted by UMAC and the Croft Institute, will explore “September 11: Two Years Later. What has Changed – where do we go from here?”

Moderated by executive director of the Croft Institute, Michael Metcalf, the panel discussion will include Nirit Ben-Ari, an Israeli peace activist, Omar Bada, a Palestinian peace activist and UM economics professor Katsuaki Terasawa.

(a) What in the fuck do Israeli and Palestinian peace activists have to do with 9/11? I honestly could give so little of a shit about people who celebrated in the streets when they learned about the attacks on the World Trade Center and Pentagon. (b) I’m not participating in any vigil in honor of the Taliban and Ba’ath Party (two groups many of whose members who have—most deservedly—died as a result of said “policies”). What an amazing display of questionable taste by Croft to have any involvement in this crapfest.

Open source FUD

Kevin Aylward at Wizbang! blames Sendmail, and by extension the Open Source movement, in part for the spread of viruses on the Internet. Specifically he claims:

Here’s the kicker – Sendmail had no capability to drop messages that contain viruses.

Sorry, Kevin, but I call bullshit.

  • Sendmail can scan for viruses using the “milter” (mail filter) facility, which has been present for several years. Get up to date on the technology before you start spreading crap.
  • There are numerous alternative mail transport agents (MTAs) to Sendmail that also have hooks for virus scanning, including Postfix, Exim, and (if you can stand DJB-ware) qmail.
  • Virus scanners can also be hooked into procmail, if you don’t actually want to futz with your MTA configuration.
  • Specifically, Debian and other Linux distributions include a complete, free anti-virus scanning suite that integrates with almost any mail server (specifically, clamav and amavisd); it also includes hooks for spam trapping. I had it set up and running within an hour on the box I administer at work. It’s catching all of our Sobig.F messages, and not even spamming unrelated parties with bogus “you sent me a virus” messages like certain commercial systems I could mention.

Yes, I freely admit that sendmail is a piece of bloated, outdated shit that I won’t run on any server I administer. But blaming sendmail, when you should blame lazy admins and ISPs who can’t be bothered to avail themselves of the available free virus scanners (not to mention the ample commercial offerings), is just silly, and exactly the sort of crap you’re complaining about in the behavior of some open source advocates.

Brock has more on this theme here.

Perestroikans and the obsession with "rational choice"

Matthew at A Fearful Symmetry notes trouble brewing at Harvard’s Kennedy School of Government between “rational-choice theorists” and “more traditional political scientists,” according to NYT Magazine writer James Traub.

This description belies a lack of understanding about political science. We can generally break the history of political science into two eras: the pre-behavioral period and the post-behavioral period. During the pre-behavioral period, political scientists basically did two things: descriptive analysis of political institutions and what I’d term “normative political theory,” a nebuolous field that generally involves the study of political phiolosophy, with a nice dash of prescriptivism thrown in just for entertainment value. Woodrow Wilson did a bit of the former, when he wasn’t being a prescriptivist or a racist (the three occupations kept him fairly busy).

Then came World War II, James Gallup, and the sample survey. A bunch of folks at Columbia and Michigan (among other places) decided that it might be a good idea to test whether all these theories people had come up with about the behavior of voters during the “pre-behavioralist” period were valid (and it turns out that they basically were wrong). Thus was born the behavioral revolution in political science—and, arguably, the entire idea of the study of politics using the scientific method (or empiricism).

Note that this account has not used the words “rational choice.” That’s because rat choice really has almost nothing to do with behavioralism. The roots of rat choice come from economics (notably the work of Anthony Downs and Mancur Olson), and in particular the idea of “utility maximization”; rational choice theory generally argues that people behave in a way that has the maximum possible benefit to themselves (“utility”). Utility has proved rather annoying to quantify in political science (in economics, utility maps rather nicely to monetary units; in political science, about the best we’ve done is OxPoints).

However, there are plenty of other ways to explain behavior in political science other than rational choice. Many behaviorists today—including myself—incorporate rationalist explanations with sociological and psychological explanations to formulate their theories of political behavior, which they then test empirically using either experimental or survey-based data with statistical techniques (usually, although not always, borrowed from other fields, including mathematical statistics, economics, psychology, and biostatistics).

More importantly, this ignores other techniques used in other subfields of political science. In international relations (and some other parts of the discipline), many theories are formulated using game theory, which has some links to rational choice (mostly in terms of the institutions the procedures were developed at, most notably the University of Chicago and University of Rochester), or more advanced mathematical modelling techniques; sometimes these techniques are linked with rational choice under the rubric of “formal theory.” Some of these techniques (ironically, like normative political theory) have not historically been subjected to any real-world testing; however, now there is some interest in doing this through the NSF’s promotion of a series of EITM (Empirical Implications of Theoretical Models) workshops and works like that of Rebecca Morton.

So describing what I do as “rational choice” is something of a misnomer. It would be like describing all normative political theorists as “Plato scholars,” or all economists as Keynesians. The truth is that there’s room for many different perspectives on the study of politics in our discipline.

The problem is that I’m not sure most Perestroikans are aware that there are multiple empirically-based perspectives. For example, the book the Perestroikans hold up as validating their point of view comes from two political scientists grounded in the empiricist, Michigan school tradition. Now, I’ll agree that some leading journals often mistake sexy methodology with substantive importance; like in specifying any theory, simpler methods are preferable to complex ones—given similar explanatory power. (This also goes for theoretical articles; if the APSR is to be a journal that everyone with a graduate education can read, surely we should expect prose that is penetrable to non-specialists.) But to reject empiricism outright in a discipline that has science as part of its name is, in my view, a bridge too far.

Daniel Drezner has more on the Summers piece this morning, which will no doubt spark an interesting discussion, while this post (inexplicably) makes John Jenkins is glad he’s a theorist. He writes:

While I'm certain that good work can, has, and will continue to be done this way in political science, more often than not we end up with analysis so blatant in its biases that it's entirely useless. I am reminded of a study that we looked at in one of my methods classes that determined that, on the whole, those who were of [M]exican descent were paid far less than those who weren’t in some city in Texas. It failed utterly to account for how long the people had been in America (i.e. first-generation immigrants tend to work in low-paying jobs because of lack of training and lack of facility with English) and resolutely concluded that the disparity was due exclusively to racism. Anyone think there was a foreordained conclusion there?

Can you say omitted variable bias? Bad research is bad research, whether it’s empirical or not…

More to the point, I don’t think empirically-oriented political scientists claim to be able to make predictions on a par with those made by sciences solely governed by physical laws. In any event, that’s fundamentally not the point of science, which seeks explanations rather than predictions. Just because, as John puts it, “people will do stupid shit sometimes” doesn’t necessarily mean that their behavior isn’t at least somewhat explainable.

Shit, fan on intercept course

Can I just hide for the next few months while the furor over this proceeds without my involvement? Please?

More details are in this Daily Mississippian story. And if you think this was done without the “high sign” from U of M Chancellor Robert Khayat, you haven't been paying much attention to how Ole Miss works.

Patrick Carver is displeased (along with the rest of the Alumni Association, no doubt). For the record, I've always thought the Colonel was a pretty dumb mascot, but in a league where Auburn can’t even figure out what its mascot is, Vanderbilt has a “commodore,” Georgia has a succession of ugly-ass dogs, and Alabama has the inexplicable “crimson tide,” it’s pretty clear that Ole Miss isn't exactly out-of-place in that regard.
