More on the looting phase of the education reform movement

Having watched the rise and fall (?) of the education reform movement for years now, I often find my attention split the story and the metastory. The story is what's being done in education, how it's working and what should be done differently. The metastory is about the way the reform narrative grew and entrenched itself (particularly with parts of the left) and about the way movement reformers (again, particularly on the left) failed to deal with certain longstanding concerns.

Putting aside the question of political agendas (which really shouldn't be considered when assessing arguments -- bad motives don't preclude good reasoning), the concerns fell into three broad categories:

1. The underlying pedagogical and economic assumptions were flawed;

2. There were intractable data issues that were being overlooked;

3. The system was vulnerable to (and had huge incentives for) gaming at a level that could undo any of the benefits that might come from the proposed reforms.

It is the third concern that prompted me to speculate about affinity effects (a point disputed here). Though evidence supporting all three has been accumulating for years, discussions of the first two got very technical very quickly. Support for the third, though, was obvious on a common sense level.

When a group repeatedly fails to notice something as it becomes increasingly obvious, you can legitimately start looking for some external influence, and the problem with gaming has become increasingly obvious. We started with clear vulnerabilities, then saw the rise of charismatic figures who asked us to trust them with tremendous amounts of money and power based on extravagant but questionable claims. Almost immediately after this, reports starting flowing in of suspicious test results, extensive student dumping and other signs of aggressive data manipulation.

How were so many otherwise alert and skeptical movement reformers caught off guard by problems anyone could have seen coming? I believe part of the answer lies in the culture and narratives of the reform movement. Cultural affinity meant that reformers (who generally had good intentions themselves) tended to project similar values on those who displayed the correct cultural signifiers while hero/villain narratives made it difficult to accept the idea that some of those cast in heroic role might be corrupt while some of those cast in the villainous parts might be right.

Though overt cheating has been getting most of the press lately, larger, more systemic data manipulation is potentially the bigger concern. Mike the Mad Biologist has been on this beat and sends us to this depressing data point.[emphasis added]
One of the first things a visitor sees when stepping into Kipp Academy is a graph that shows how Kipp is outperforming Metro schools in every subject.

However, Kipp Academy is also one of the leaders in another stat that is not something to crow about.

When it comes to the net loss of students this year, charter schools are the top eight losers of students.

In fact, the only schools that have net losses of 10 to 33 percent are charter schools.

"We look at that attrition. We keep an eye on it, and we actually think about how we can bring that back in line with where we've been historically," said Kipp Principal Randy Dowell.

Dowell said Kipp's 18 percent attrition is unacceptable.

MNPS feels it's unacceptable as well, because not only are they getting kids from charter schools, but they are also getting troubled kids and then getting them right before testing time.

"That's also a frustration for the zoned-school principals. They are getting clearly challenging kids back in their schools just prior to accountability testing," said MNPS Chief Operating Officer Fred Carr.

Nineteen of the last 20 children to leave Kipp Academy had multiple out-of-school suspensions. Eleven of the 19 are classified as special needs, and all of them took their TCAPs at Metro zoned schools, so their scores won't count against Kipp.

"We won't know how they perform until we receive results and we see. We would be happy to take their results, frankly. The goal is getting kids ready for college. The goal is not having shiny results for me or for anyone on the team," Dowell said.
There's a surreal quality to Dowell's responses here. The kind of attrition we're talking about in this case is almost entirely at the administrator's discretion. What's more, it generally takes a great deal of time and paperwork to make it happen.

As mentioned before, these schools already have selection bias and social norming working in their favor. If, on top of that, a principal like Dowell selectively gets rid of almost one out of five students based on behavior and performance, it is difficult for a school not to look good.

In a sane society, this would have been the lead story the day it broke

David Biello writing for Scientific American (via Thoma):
That's the message from the U.S. Geological Survey's evaluation of how the U.S. is managing its aquifers. Or mismanaging. For example: water levels in the aquifer that underlies the nation's bread basket have dropped in some places by as much as 160 feet.

The rest of the world isn't doing any better. A conference of water scientists just issued the so-called Bonn Declaration, which declares that this lack of foresight will cause the majority of people alive in 2050 to face "severe" freshwater shortages.

Ethics and Ayn Rand

James Kwak:
This idea is obviously echoed in Ayn Rand’s novels, which celebrate the individual genius standing out against the backdrop of collectivist mediocrity. It has also trickled into the contemporary conservative worship of the ultra-rich. The phrase today is “job creators” (whatever that means), but it has the same moralistic overtones as in Nietzsche and Hayek—a class of people who are better than the rest of us, on whom we depend for our salvation and prosperity, and whom we should not presume to question or constrain through, say, safety regulation or higher taxes (“penalizing success,” in the jargon).
This really has been one of the more insidious ideas of the twenty-first century-- that wealth and success are evidence of moral character.  One problem with this philosophy is that it replaces a creed of "it isn't whether you win or lose, it is how you play the game" with an unfortunate alignment between moral virtue and business success.  Under these conditions, how do you restrain the quest for wealth to within a code of ethics?

Instead we have a purely outcomes based ethic, that talks about the good that comes from the wealthy without asking hard questions -- like would things be better if wealth were more equal?  In particular, the logical connection between rich people becoming more rich and more employment opportunities being created are less than completely clear.  I don't want to say that the effect size is actually zero, but rather that it seems odd to neglect other possible sources of variation.

The Project Gutenberg Project

Joseph and I have been going back and forth on the best way to get the most out of the tidal wave of open data of which we are only seeing the beginning.

Joseph tends to be more skeptical on this subject. He almost has to be. He's approaching this both as an epidemiologist (where privacy and ethical issues create huge headaches) and an academician (where open data can create tremendous perverse incentives to rush out mediocre work in order to beat out other researchers looking at the same data). The promise of open data is very much field specific.

I tend to be more optimistic about the subject. I'm more the data miner of the blog and to find myself living in an age when anyone with a refurbished desktop computer, a copy of R and Python and a decent internet connection can do real, interesting research is tremendously exciting.

There is at least one area, though, where I am possibly more skeptical than Joseph and that's in the chances of these huge data initiatives self-organizing along anything near an optimal configuration...

I started to write something here about market forces in research and incentives and non-rival goods but then the phone rang and by the time I got off I realized that would be a lot of work (at least it would if I did enough research to make sure I wasn't making an idiot of myself). Chances are, that discussion would just be a long winded way of saying if we want to effectively coordinate all these researchers so that information flows where it needs to flow and data is fully explored and we can keep track of what's going on, we need to think this thing through.

Which brings me to the Project Gutenberg Project. Project Gutenberg has, of course, a huge and growing database. It's set up to be researcher-friendly and the system readily lends itself to automated approaches. The possibilities for text-mining are endless and a tremendous number of interesting research questions can be addressed with nothing more than a reasonably up-to-date computer and some free software (I previously posted a couple of examples here).

This would seem to be an ideal test case for setting up procedures and sites for dealing with large, open databases . Here are a few possibilities:

A place to submit and comment on proposed hypotheses;

A place to report preliminary findings;

A place to report negative findings;

A place to report confirmation of previous findings;

A database connecting approaches, hypotheses and data points;

Multiple ranking systems;

A way of identifying under-explored parts of the data.

Obviously this is a first pass and I'm just throwing out some ideas. Some might be impractical. Others, as Joseph would point out, will not be applicable to other data sets. And I have a nagging feeling that I've left something obvious out.

But that, of course, is the nature of a blog post.

Maybe they're hinting at something

I've been experimenting with different blog formats over the past few years with a couple of pop culture blogs and a fairly serious one (You do the math) on education. They've definitely been on the back burner recently but they are active and they continue to improve slowly in traffic and page rank so if I decide to put one in gear (which I may do with the You Do the Math fairly soon), I won't have to start from zero.

These sites run ads. To date I haven't seen any money from them (my account is around forty dollars and you apparently have to have one hundred for them to cut you a check), but like I said they've been in a groundwork stage and I have plans to go after at least one of them more aggressively in the future.

Which is why this email from Google is a tad troubling:

Hello,

Here's the funny part... There doesn't seem to be any way for me inform them of my ownership other than to click the link and cancel. There is no link in the middle paragraph. The email was sent from a no-reply address. When I go to the Adsense contact page I am told that my account is not eligible for direct email consultation and I am limited to "specialized contact forms," none of which seem to come even close to fitting my situation.

Are they trying to get me to leave or are they really this bad at business communications?

Weekend blogging -- Uncle Art's Funland

Art Nugent doesn't have the mathematical following that Dudney or Loyd (he seldom hit the depths of those two), but he was a pretty good puzzle maker and a damned fine cartoonist and his output was extraordinary. For more than forty years he put out newspaper features and comics pages filled with puzzles, games, riddles, activities and magic tricks.

Spinach is supposed to make you stronger -- Infrastructure and the Kinsley/Krugman fight

Virtually everyone who reads this blog has heard about (and is probably sick of hearing about) Michael Kinsley's contrarian defense of austerians that ended with this analogy:
Austerians don’t get off on other people’s suffering. They, for the most part, honestly believe that theirs is the quickest way through the suffering. They may be right or they may be wrong. When Krugman says he’s only worried about “premature” fiscal discipline, it becomes largely a question of emphasis anyway. But the austerians deserve credit: They at least are talking about the spinach, while the Krugmanites are only talking about dessert.
To get a feel for just how odd this analogy is, you need to remember that a large part of this 'spinach' is saying no to people who want to borrow money almost interest-free and spend it on infrastructure, education and research thus avoiding far greater costs in the future.

These are all urgent issues but the infrastructure crisis in particular demands immediate action. Civil engineers have been ringing this alarm bell for years:
Back in March, when the American Society of Civil Engineers issued an infrastructure report card for the entire country, its very best grade — a B-minus — went to solid-waste disposal. Thanks to our decent progress in recycling, the United States’ overall grade-point average in subjects ranging from aviation to water systems actually ticked up from the previous GPA.

To a pitiful 1.30, that is, on a 4.00 scale.
Those warnings became considerably less abstract yesterday:
SEATTLE — A large section of a bridge on Interstate 5 north of Seattle collapsed Thursday evening, sending vehicles and people plunging into the swirling, frigid waters of the Skagit River.
Three people were hospitalized in stable condition, officials said. No one was killed.

The bridge failed without warning between the towns of Burlington and Mount Vernon on the major route linking Seattle with the Canadian border, the Washington State Patrol said.
"Without warning" here is a bit of a relative term:
The 58-year-old bridge in Washington, a crucial link to the Canadian border traveled heavily by trucks, was inspected every two years, most recently in November, state Department of Transportation spokesman Bart Treece told the Los Angeles Times.

“It’s an old bridge. We have to look into the specifics. We do have a lot of old, aging structures, and a lot of them hold up really well,” he said.

The National Bridge Inventory lists the bridge as “functionally obsolete,” with “somewhat better than minimum adequacy to tolerate being left in place as is.” It received a sufficiency rating of 57.4 out of 100.



Putting aside for the moment the question of public safety, the economic impact of bad infrastructure can be huge (from the same story):
Washington’s main north-south thoroughfare, though, was likely to remain closed 60 miles north of Seattle for an indefinite period, state officials warned. The nearly 71,000 vehicles a day that travel the bridge between Mt. Vernon and Burlington were diverted through city streets to another nearby bridge.
Just to be clear:

dessert = making repairs now

spinach = deferring repairs now and making more costly ones later when interest rates will be higher

Kinsley's analogies are like America's bridges; they need a lot of work.



Notes on an unwritten paper -- Naive Bayesian Classifiers and Order of Composition

[Update: I've got some more thoughts on Gutenberg-based research in my latest post.]

I'm planning on writing some posts on the potential of and the potential concerns about open data (possibly even getting Joseph to join in) so I thought I'd dust off a somewhat relevant idea I had a few years back. If anyone wants to see if they can get something publishable out of this, feel free. In the meantime, I plan on getting some mileage out of it as an example.

A few years ago, I wrote some code for text mining. It was really basic, standard stuff -- using naive Bayesian classifiers and n-grams (normally techniques for assigning authorship) -- but it worked well and was fun to play around with. I used various books from Project Gutenberg as test data and selected authors with styles and backgrounds ranging from close (Dickens and Trollope) to out there (Thorstein Veblen) with a translation of Verne as someone neutral. The two Victorians also had the advantage of having written lots of books over many years.

The idea was to approach this less as a classification problem and more of a question of distance between points in a literary space. Here the "likelihood score" was more a measure of similarity. As you would expect, Great Expectations was more similar to Nicholas Nickleby than to Barchester Towers, more similar to Barchester Towers than to a translated Master of the World and more similar to Master of the World than to Theory of the Leisure Class. It also worked as expected when you compared works of the same author written at different points in his career: Great Expectations (1860 to 1861) was more similar to Our Mutual Friend (1864 to 1865) than to Nicholas Nickleby (1838 to 1839).

Obviously this was a tiny trial run, but it did suggest that there's something out there, as did a recent literature search which turned up at least one related paper from 2011 ("Predicting the Date of Authorship of Historical Texts" by A. Tausz) which used NBCs to determine absolute rather than relative dates. Still even with Tausz' paper (which is very interesting, by the way) there still should be room for research into intra-author questions and, more importantly, into lots of other questions using data from project Gutenberg.

And on top of that you can apparently find interesting stuff to read at the site as well.

Scandal, metareporting and the dumber-reader theory

Everybody has heard of the greater fool theory of investing where you buy a stock not because you think its assets are undervalued or because there's a good chance that the company will make money but because you believe there is someone out there who will pay significantly more than you paid.

I've noticed a somewhat analogous trend in journalism today, particularly involving the coverage 'scandals.' I apologize for the quotes but they're there for a reason I'll get to in a bit. In the traditional model of reporting, the journalist implicitly claims that the information being reported is accurate, representative and significant enough to justify the readers' time.

Over the past few years, though, journalists seem to have gotten more likely to downplay these traditional elements (what we might call the fundamental value of the story) and focus on what the impact of the story will be if people other than the reader believe it (the dumber-reader theory). In generic form, the stories go something like this: "A made accusations against B. There is no reason to believe these accusations but if they gain traction, they could hurt B."

Perhaps the most dramatic example of the past few years was swiftboating where most of the attention was paid to how Kerry's handling of the charges would affect his campaign while relatively little was given to the charges' validity (a question that in previous times would probably have been considered a necessary condition for the story to advance).

Don't get me wrong. Coverage has always included questions about the impact of scandals, but it seems like the process before had more of a tree structure: ask question A and then, based on the answer, ask either question B or C. I'm not saying that this rose to the level of hard and fast rule, just that it was the norm. First you asked if an accusation was true. If the answer was yes you asked how serious was the offense; if the answer was no you asked if the accuser had been deliberately misleading. And so on...

I can see how moving away from that structure is a good thing for journalists. For the rest of us, however, it does not look like a good thing at all.

Pets

Frances Woolley:

Indeed, when a person selects a pet, life expectancy is one of the last things considered (see, for example, this pet selection guide, or this one or this one). Instead, "experts" recommend choosing a pet who will be a good match for his or her owner in terms of activity level, sociability, and so on. Good health matters - sensible owners avoid breeds prone to health problems. But not life expectancy per se.
I think there is a good point here -- life expectancy is not the only good that people are interested in.  Sure, I do not want to die young.  But if terrible quality of life was the only way to extend one's life span that would seem sub-optimal too. 

Really what we want to maximize is high quality life.  In cases where high quality and life contradict each other then one has to choose (and it is never an easy decision).  So it is not surprising that people adopt pets that they are compatible with.  But just ask a dog owner what they will do to extend the life of a sick Labrador Retriever and you might be surprised . . .

So which preference is dominant?  The breed decision or the attempt to prolong the life of one's furry friend? 

Un-self-awareness at the New Republic -- more Rhee-views

Michele Rhee has popped up in a couple of notable posts this week.

First Nicholas Lemann writing in TNR:
Rhee is not one for exquisite sensitivity. She closed schools, fired teachers, and (though she assures us that “I had never sought the limelight”) became famous. She was on the covers of Time (holding a broom) and Newsweek, and was one of the stars of Waiting for Superman. It is usually a fundamental rule of politics that a department head isn’t supposed to do anything to make her boss unpopular or to upstage him. Rhee did not follow this rule. She has a special scorn for “politics” and often praises Fenty for not considering it when making decisions, but this is both un-self-aware (Rhee’s policies were very good politics in white Washington) and impractical. We live in a democracy, so officials have to contend with public opinion and with groups organized to promote their own interests. Many American politicians over the last generation, including all of the last five presidents, have been able to push education policies in the same realm as Rhee’s in a way that kept their coalitions together. That is what Rhee and Fenty were unusually bad at doing, and Rhee’s insistence that “politics” is a terrible thing that only her opponents practice was surely a big part of the reason why.
Lemann represents the pivot phase of the press's relationship with Rhee, not quite ready to address painful topics, but moving away from the hagiography that until recently marked much of Rhee's coverage (particularly at the New Republic).

It is, of course, difficult to pivot gracefully so it's not surprising to see an awkward turn or two here. Most memorable is the description of Rhee's stated view of politics as "un-self-aware." Not only is the term itself good for a chuckle, but by this criterion Rhee's un-self-awareness would apply to the vast majority of politicians (think of all the times you've heard candidate express a similar scorn). It is the most standard of standard campaign lies, made all the more transparent by Rhee's relentless and ruthless political maneuvers (including reaching her current position by climbing over the still-warm corpse of Adrian Fenty's career).

The press is slowly coming to terms with how badly it was played by Rhee, but they are getting there. The question now is how will the fall of one reformer affect the movement? Andrew Gelman sees this as indicative of something bigger.
My impression is that there has been a shift. A few years ago, value-added assessment etc was considered the technocratic way to go, with opponents being a bunch of Luddite dead-enders. Now, though, the whole system is falling apart. We can learn a lot from tests, no doubt about that, but there’s a lot less sense that they should be used to directly evaluate teachers. We’ve moved to a more modern, quality-control perspective in which the goal is to learn and improve the system, not to reward or punish individual workers.

This shift may have not happened yet at the political level, but it’s my sense that this is the direction that things are going. The Rhee story is symbolic of the fallacies of measurement.
I'm not so sure. From the beginning there have been at least four major concerns:

1. Given the ugly nature of the data (confounded, nested, etc.) we would not get anything usable out of the two or three years of data window we would have to evaluate a teacher;

2. The test might give us an inaccurate or incomplete picture of what students were learning;

3. The system would be vulnerable to cheaters;

4. The tests would distort education priorities.

Rhee's crash drives home 3 but I don't know that it says that much about the rest which is troublesome because those are the ones that bother me more.

A smart post from Felix Salmon

Felix Salmon:

My point here is that technology has a tendency to create its own norms. The classic example is the automobile — a technology which kills more than 30,000 Americans every year. From the 1930s through the 1990s, societal norms about who roads belonged to, and what people should do on them, were turned on their head thanks to the new technology. The dangerous new activity allowed by the new technology became the privileged norm, to the point at which just about all other road-based activity — and roads have been around for thousands of years, remember, since long before the automobile — essentially ceased to exist. Eventually, we reached the point at which elected representatives were happy saying that if a bicyclist gets killed by a car, it’s the bicyclist’s fault for being on the road in the first place
.I think that this is a very interesting point at two levels.  One, is that it does point out that society can change around innovation just as much as innovation can change society.  I think that this will be broadly applicable to innovations like driverless cars that are legal nightmares now, but could easy become the standard with enough adoption.  It's never clear when a technology will win this sort of breakthrough success (the innovation grave-yard is full of such examples).  But it does point out that some classes of argument are less likely to succeed.

But the second point is also really salient -- it is often amazing how much we overlook the subsidization of activities are social norms.  We don't see the use of roads for cars and not bicycles as a subsidization of the car.  Heck, I am often annoyed by bicyclists who can't decide what set of rules they are following (when they switch back and forth between being a fellow vehicle and a pedestrian it makes me nervous as I have a life-long goal to never hit a cyclist).  But the roads could just as easily be claimed by walkers, horses, bicycles and so forth in a much easier form of mixed use.

Maybe he meant the toolbox of some economists...

Greg Mankiw has a piece up at the New York Times that opens with this assertion: "Nothing in the toolbox of economists makes us good stock pickers."

The article does a good job explaining the relevant economics concepts to a lay audience (as expected given the author), but I did notice a slight but amusing omission from this:
Advocates of market rationality now say that stock prices move in response to changing risk premiums, though they can’t explain why risk premiums move as they do. Others suggest that the market moves in response to irrational waves of optimism and pessimism, what John Maynard Keynes called the “animal spirits” of investors. Either approach is really just an admission of economists’ ignorance about what moves the market.
I'm not entirely sure Keynes would have conceded that point:
Keynes was ultimately a successful investor, building up a private fortune. His assets were nearly wiped out following the Wall Street Crash of 1929, which he did not foresee, but he soon recouped. At Keynes's death, in 1946, his worth stood just short of £500,000 – equivalent to about £11 million ($16.5 million) in 2009. The sum had been amassed despite lavish support for various causes and his personal ethic which made him reluctant to sell on a falling market when if too many did it could deepen a slump.[135]
Just imagine how much Keynes would have socked away if he didn't have that live-for-today attitude.

Weekend Blogging -- Puzzles! Puzzles! Puzzles! (from our side of the pond)

Having just done Dudney, it's only fair that we give equal time to America's turn of the century puzzle master, Sam Loyd.

If the name is new to you, here's a quick introduction from Wikipedia:
Loyd is widely acknowledged as one of America's great puzzle-writers and popularizers, often mentioned as the greatest—Martin Gardner called him "America's greatest puzzler", and The Strand in 1898 dubbed him "the prince of puzzlers". As a chess problemist, his composing style is distinguished by wit and humour.

However, he is also known for lies and self-promotion, and criticized on these grounds—Martin Gardner's assessment continues "but also obviously a hustler", Canadian puzzler Mel Stover called Loyd "an old reprobate", and Matthew Costello calls him both "puzzledom's greatest celebrity...popularizer, genius," but also "huckster...and fast-talking snake oil salesman."[4] He collaborated with puzzler Henry Dudeney for a while, but Dudeny broke off the correspondence and accused Loyd of stealing his puzzles and publishing them under his own name. Dudeney despised Loyd so intensely he equated him with the Devil.[5]
[For an in depth look at both Dudney and Loyd, Gardner is the go-to guy.]

Loyd was a master of all sorts of mathematical diversions but he is best remembered for his geometric puzzles. Perhaps the best known of these were the "Trick Donkeys." The object is to cut this picture into the three pieces indicated and rearrange them so that the jockeys appear to be riding the donkeys. No tearing or folding allowed and the donkeys cannot overlap.

One of the interesting things about this puzzle is that there are relatively few ways of arranging the pieces but people trying to solve the puzzle will almost invariably keep retrying the same unsuccessful arrangements.

Another famous puzzle (and one I'd like to revisit if I have the time) is Back from the Klondike:






From Wikipedia:
Back from the Klondike is one of Sam Loyd's most famous puzzles, first printed in the New York Journal and Advertiser on April 24, 1898. In introducing the puzzle, Loyd describes it as having been constructed to specifically foil Leonhard Euler's rule for solving any maze puzzle by working backwards from the end point.[1]
The following are Sam Loyd's original instructions:
Start from the heart in the center. Go three steps in a straight line in any one of the eight directions, north, south, east, west, northeast, northwest, southeast, or southwest. When you have gone three steps in a straight line you will reach a square with a number on it, which indicates the second day's journey, as many steps as it tells, in a straight line in any one of the eight directions. From this new point, march on again according to the number indicated, and continue on in this manner until you come upon a square with a number which will carry you just one step beyond the border, thus solving the puzzle.
Over at the Mathematical Association of America site. Ed Pegg Jr. has put Loyd's magnum opus, Sam Loyd's Cyclopedia of 5000 Puzzles, Tricks, and Conundrums online.

Here are some sample pages including the yellow-menace puzzle, Get Off the Earth. Solutions are found in the links that follow each page.

At last a candidate Maureen Dowd can support

Jonathan Chait has a good column about President Obama's recent comments about "going Bulworth," an allusion to the 1998 Warren Beatty movie about a politician who as a result of a drunken but honest rant finds his career reinvigorated.
The trouble is that these [frank] answers, while true, don’t actually help Obama. Any political scientist will tell you that the scope for possible legislation in this term is very narrow: The median House member is a very conservative Republican who represents a district that voted for Mitt Romney, and whose biggest political risk is losing a primary to an even more conservative Republican.

But most political reporters and analysts don’t pay attention to the political science. They like narratives that revolve around the president as a protagonist. When you confront them with structural analysis that confounds their narratives, they just get upset with you. It serves no purpose. That’s why I advised Obama to use “less real talk and more bullshit.”

A post-presidency Obama who actually spoke his mind, rather than fashion himself a post-partisan eminence, as post-presidents do — now that would be awesome. But the reason politicians don’t go Bulworth is that it doesn’t work. The truth about legislative dynamics is complicated and depressing. People don’t want to hear it.

Last night, for example, Obama said of the IRS scandal, “The good news is it’s fixable, and it’s in everyone’s best interest to work together to fix it.” That is some prime-caliber bullshit. Of course it’s not in the Republicans’ best interest to fix the problems with IRS enforcement. It’s in their interest to prevent any fix and let the problems linger as long as possible.

But if he had said that, there would have been a huge outcry, and probably a presidential apology. Nobody objected to Obama’s faux-naïve claim that Republicans will naturally want to solve the problem. Bullshit works. Bulworth doesn’t.
Bulworth is variant of the "straight-talking everyman takes control from the politicians" genre. Bulworth starts out as a standard politician then becomes a straightshooter, but the underlying fantasy is basically the same as that of Dave and Mr. Smith Goes to Washington: a political savior who would cut through the corruption and needless complexity with plain talk and common sense.

Not surprisingly, this notion holds a special appeal for Maureen Dowd.
Mr. Obama’s errors on the helter-skelter stimulus package were also self-induced. He should put down those Lincoln books and order “Dave” from Netflix.

When Kevin Kline becomes an accidental president, he summons his personal accountant, Murray Blum, to the White House to cut millions in silly programs out of the federal budget so he can give money to the homeless.

“Who does these books?” Blum says with disgust, red-penciling an ad campaign to boost consumers’ confidence in cars they’d already bought. “If I ran my office this way, I’d be out of business.”
