Weekend blogging -- save this one for late in the day

As a former creative writing major, I probably shouldn't admit this but I wasn't really familiar with Paul Verlaine and I had no idea that Clair de lune was inspired by his poem of the same name.

Nothing more to add in the way of comment except the recommendation that you wait till late in the evening before pushing play.




Clair de Lune by Paul Verlaine

Your soul is a chosen landscape
Where charming masqueraders and bergamaskers go
Playing the lute and dancing and almost
Sad beneath their fanciful disguises.

All sing in a minor key
Of victorious love and the opportune life,
They do not seem to believe in their happiness
And their song mingles with the moonlight,

With the still moonlight, sad and beautiful,
That sets the birds dreaming in the trees
And the fountains sobbing in ecstasy,
The tall slender fountains among marble statues.

Putting Arne Duncan's remarks in context

“It’s fascinating to me that some of the pushback is coming from, sort of, white suburban moms who — all of a sudden — their child isn’t as brilliant as they thought they were and their school isn’t quite as good as they thought they were, and that’s pretty scary,” Arne Duncan said. “You’ve bet your house and where you live and everything on, ‘My child’s going to be prepared.’ That can be a punch in the gut.”

To understand why Duncan hit such a nerve, you need to consider the long and complicated role that racial politics have played in this debate.

The public face of the education reform movement has always been pictures of eager young African-American and Hispanic children. Not only has the movement been sold as a way of helping these children but people who object to parts of the reform agenda have often been accused, implicitly or explicitly, of not wanting to help children of color. This naturally has caused some resentment by those, such as myself, who disagree with many of the proposals and who have actually taught in places like Watts and the Mississippi Delta, but there are more serious sources of tension.

For starters, with certain notable exceptions, the leaders of the reform movement tend to be white or Asian (for example, "2012 members of TFA are 62 percent white and only 13 percent African American"). By comparison, the tenured and/or unionized teachers who have paid the highest price in terms of policy changes and school closures have been disproportionately African-American. Under these circumstances, you can imagine the reaction when education reformers make statements like “I think the best thing that happened to the education system in New Orleans was Hurricane Katrina.”


(as a side note, Jay Altman is one of the best paid administrators in the city)

Even more troubling is the disconnect between the marketing and the actual focus of the reform movement. Though the defining image of the movement is of a reformer surrounded by a happy group of African-American or Hispanic elementary school students in brand-new charter school uniforms, almost none of the major reform initiatives are specifically targeted at helping these particular kids. Initiatives like Common Core and teacher accountability are being proposed for all schools. Sometimes reformers will argue that though these changes affect all students they will have their greatest impact on disadvantaged kids. Other times, they simply let their photo ops do the talking for them.

Even TFA, which was held up as the definitive program for helping kids in poor neighborhoods, is now focusing more on developing leaders and administrators and is actually providing teachers for areas like Chicago and even more notably Huntsville that have a surplus of highly qualified instructors applying for the jobs.

Perhaps people did read too much into Duncan's comments but, considering recent history, you can see how some might react badly to his suggestion that race was a factor in people's decision to criticize his proposals.

So what am I missing?

This conclusion of a piece by Megan McArdle was confusing:

Those victims should not be abandoned -- no American should be allowed to starve in retirement. But the federal government should not step in to guarantee those false promises, any more than it should attempt to re-create the vulnerable housing developments that were washed away by the storm.

The context is that of the Detroit bankruptcy, where retirees are getting 16 cents on the dollar.  There is also issues with health care that I am not clear about, but I am presuming that these people are eligible for Medicare (they are not eligible for Social Security since they did not participate in the contributions).

What I don't understand is what the path forward being proposed is?  We cannot recover the money from past administrations, and the issues with the pension are complex.  Fault is very hard to assess.  So the choices seem to be: short other creditors, default on pension obligations, or find another source of funds.  Unless the suggestion is that the state should backstop these obligations, I am unclear what the source might be? 

I am hoping that further information makes this situation seem less dire. 

"As God as my witness..." is my second favorite Thanksgiving episode line

If you watch this and you could swear you remember Johnny and Mr. Carlson discussing Pink Floyd, you're not imagining things. Hulu uses the DVD edit which cuts out almost all of the copyrighted music. .

As for my favorite line, it comes from the Buffy episode "Pangs" and it requires a bit of a set up (which is a pain because it makes it next to impossible to work into a conversation).

Buffy's luckless friend Xander had accidentally violated a native American grave yard and, in addition to freeing a vengeful spirit, was been cursed with all of the diseases Europeans brought to the Americas.

Spike: I just can't take all this mamby-pamby boo-hooing about the bloody Indians.
Willow: Uh, the preferred term is...
Spike: You won. All right? You came in and you killed them and you took their land. That's what conquering nations do. It's what Caesar did, and he's not goin' around saying, "I came, I conquered, I felt really bad about it." The history of the world is not people making friends. You had better weapons, and you massacred them. End of story.
Buffy: Well, I think the Spaniards actually did a lot of - Not that I don't like Spaniards.
Spike: Listen to you. How you gonna fight anyone with that attitude?
Willow: We don't wanna fight anyone.
Buffy: I just wanna have Thanksgiving.
Spike: Heh heh. Yeah... Good luck.
Willow: Well, if we could talk to him...
Spike: You exterminated his race. What could you possibly say that would make him feel better? It's kill or be killed here. Take your bloody pick.
Xander: Maybe it's the syphilis talking, but, some of that made sense.

Equality and Adam Smith

Bill Gardner from the Incidental Economist (in comments):

As you know, Adam Smith was a moral philosopher. You might want to ponder this quote from the Wealth of Nations:

“No society can surely be flourishing and happy, of which the far greater part of the members are poor and miserable. It is but equity, besides, that they who feed, clothe, and lodge the whole body of the people, should have such a share of the produce of their own labour as to be themselves tolerably well fed, clothed, and lodged.”

I think that this really is the piece that modern objectivists (Randians) miss.  Even in Atlas Shrugged, the hyper-capitalist society was clearly defined as being better for the average worker.  In fact, the story of the company becoming socialist suggested that socialism under-mined values like generosity. 

The notion that an equitable society is a better society is very important and yet seems to be increasingly lost in the rhetoric.  When we have a high unemployment rate, it cannot merely be laziness that prevents work and it seems that we are having trouble with the most expensive part of the formulation (lodged --it is housing that is the big expense these days). 

Now before the argument that this inequality was necessary for progress comes into being, remember that Adam Smith celebrated a nation of shopkeepers, not of corporations. 

Teacher incentives

Dana Goldstein writes about a program that gives a $20,000 bonus to teachers who transfer to "high poverty, low test score" schools.  These are all established mid-career teachers, not ivy-leaguers parachuted in to help.  They showed benefit in elementary schools but not middle school.  All of these transfers were inter-urban.

I have two thoughts.  One, huge merit pay bonuses are the precise opposite of revenue neutral.  There is no evidence that cutting everyone's pay to afford these bonuses for some teachers would be a cost-effective strategy.  Its an average causal effect applied to a population already getting an underlying rate of compensation.  So what this really has to be judged against are other interventions that would spend the same money in different ways. 

Two, the political feasibility seems low.  So long as education is funded via local taxes, it seems challenging to build support for a program to pull good teachers out of well funded schools and push them into high poverty area schools (almost certainly with lower funding).  Just how one might build the political coalition to do this (without encouraging mass abandonment of existing public schools) seems to be a open question.

You will never guess who I'm quoting...

And, God help me, she pretty much nails it:

There’s much more to the fight than simple left-right divisions. The Common Core peddlers include meddling, Fed Ed Republicans from Jeb Bush and Mike Huckabee to progressive billionaires Bill and Melinda Gates to Newscorp. media giant Rupert Murdoch and dozens of educational corporate special interests that stand to gain billions from the Common Core testing/textbook/data-mining boondoggle.

I have to give credit where credit is due, even if it costs us at least one loyal reader.

Education blogging -- Common Core, accountability and the cost of deadwood

I've started digging into the Common Core standards and one of the things that hit me was the large amount of what I would consider deadwood, topics of limited value that take up valuable class time (my favorite example is synthetic division, but there are plenty of others).

The damage caused by deadwood is not that great when teachers are allowed some leeway in deciding what to focus on, but in an age of standardized tests and fetishized accountability, teachers are forced to make difficult decisions. Math teacher Gary Rubinstein has a truly depressing example.

When teachers have to teach too many topics, they do not have time to cover them all in a deep way.  The teacher, then, has to choose which topics to cover in a meaningful way, and which to cover superficially.  It would be as if an English teacher was told to cover fifty novels with her class.  Not being able to have her classes read all fifty books, she would pick some to read fully while having her class read excerpts or even summaries of the other ones.

I got to witness an extreme example of this decision making when I graded the Geometry Regents at the centralized grading center this past June.  A huge part of Geometry, in my mind the most important part, is deductive proofs.  I’d say that over half of a ‘true’ Geometry course would involve proving different theorems.  Well, on the Geometry Regents these proofs are not a large percent of the test, less than ten points out of eighty.  So on the June Regents the last question on the test, a six point question, was the proof question and I was assigned to grade about 200 papers from a school, I won’t say which one, to grade.  As I graded I noticed that many of the students left the proof blank.  By the end of my grading I realized that out of 200 papers, all that could have received up to 6 points for the proof — a total of 1,200 potential points to have been earned on this question, I had awarded only two points total.  That’s two points out of a possible 1,200.  I asked around and the consensus was that teachers, knowing that proofs would take months to cover but be only worth less ten percent of the points on the test, would be too risky to teach.  All the time spent on this tough topic would only, at best, get the students a few extra points while they would lose all that time they could use to teach some of the easier topics that were more likely to be on the test.

Of course, we could have a long discussion on whether proofs belong in HS math classes (I tend to agree with Rubinstein on this one, at least when it comes to geometry), but it's important to realize that's not what happened here. There was no discussion. No arguments were made. No supporting data was gathered. The people who wrote the curriculum simply dodged the question of what to leave out.

When you overstuff a curriculum you guarantee that certain topics will be skimmed or skipped entirely and when you apply tremendous pressure on teachers to raise test scores, you force teachers to make the kind of choices you've seen here.

Antibiotics: an ever evolving story

I really think that the issue of antibiotic resistance gets too little play, so I am happy to see it discussed -- even if the discussion errs on the alarmist side.  In particular, I am unclear as to why we can't rotate antibiotics, why we even imagine that antibiotic soap is a good idea, and would be interested to hear a good reason for the routine use of antibiotics in raising cattle. 

The last is the strangest -- we are subsidizing meat production by not making farmers pay for the externality of antibiotic resistance.  I have no trouble with meat consumption, but it is unclear to me that it is an ideal target for subsidy given the high energy costs of that food source. 

However, it is true that we would still have options post-antibiotics.  Alcohol, heat treatments, and, surprisingly, silver remain effective despite antibiotic resistance.  Having said that, there is no reason we couldn't be doing more to make use of these techniques and rely less on the medications to which germs become resistant with time. 

Ed reform background reading -- three from Wikipedia

I know this is rich coming from a blogger but too many people are joining in on the ed reform debate without having taken the time to learn the basics (Frank Bruni being a veritable poster child), particularly when it comes to curriculum reform and Common Core. Below I picked three topics that are important and generally well known among people who have been in the weeds of the education debate but which seldom show up in the standard coverage. If you're interested in this debate, they're worth checking out.

The first is one of the biggest education reform initiatives to predate the current era. It had striking parallels to many of the current initiatives and was often supported by almost identical rhetoric but it seems to have dropped down the memory hole.


New Math

New Mathematics or New Math was a brief, dramatic change in the way mathematics was taught in American grade schools, and to a lesser extent in European countries, during the 1960s. The name is commonly given to a set of teaching practices introduced in the U.S. shortly after the Sputnik crisis in order to boost science education and mathematical skill in the population so that the perceived intellectual threat of Soviet engineers, reputedly highly skilled mathematicians, could be met.
...
Mathematicians describe interesting objects with set-builder notation. Under the stress of Russian engineering competition, American schools began to use textbooks based on set theory. For example, the process of solving an algebraic equation required a parallel account of axioms in use for equation transformation. To develop the concept of number, non-standard numeral systems were used in exercises. Binary numbers and duodecimals were new math to the students and their parents. Teachers returning from summer school could introduce students to transformation geometry. If the school had been teaching Cramer's rule for solving linear equations, then new math may include matrix multiplication to introduce linear algebra. In any case, teachers used the function concept as a thread common to the new materials.

Philosopher and mathematician W.V. Quine wrote that the "rarefied air" of Cantorian set theory was not to be associated with the New Math. According to Quine, the New Math involved merely..."the Boolean algebra of classes, hence really the simple logic of general terms."

It was stressed that these subjects should be introduced early. The idea behind this was that if the axiomatic foundations of mathematics were introduced to children, they could easily cope with the theorems of the mathematical system later.

Other topics introduced in the New Math include modular arithmetic, algebraic inequalities, matrices, symbolic logic, Boolean algebra, and abstract algebra. Most of these topics (except algebraic inequalities) have been greatly de-emphasized or eliminated in elementary school and high school since the 1960s.

The second is a widespread though perhaps fading approach to running a business. Outside of various questionable theories of incentives, it might be the most influential set of private sector ideas in the reform movement. (For a more detailed account of the relationship, check out this article by Shawn Gude)

Scientific Management

Its development began with Frederick Winslow Taylor in the 1880s and 1890s within the manufacturing industries. Its peak of influence came in the 1910s; by the 1920s, it was still influential but had begun an era of competition and syncretism with opposing or complementary ideas.

Although scientific management as a distinct theory or school of thought was obsolete by the 1930s, most of its themes are still important parts of industrial engineering and management today. These include analysis; synthesis; logic; rationality; empiricism; work ethic; efficiency and elimination of waste; standardization of best practices; disdain for tradition preserved merely for its own sake or to protect the social status of particular workers with particular skill sets; the transformation of craft production into mass production; and knowledge transfer between workers and from workers into tools, processes, and documentation. 

Scientific management's application was contingent on a high level of managerial control over employee work practices. This necessitated a higher ratio of managerial workers to laborers than previous management methods. The great difficulty in accurately differentiating any such intelligent, detail-oriented management from mere misguided micromanagement also caused interpersonal friction between workers and managers.

The third is rather specific and it's perhaps more up-and-coming than big, but it has some powerful supporters and is already having a having a major impact, particularly in mathematics education.

Deliberate practice

Psychologist K. Anders Ericsson, a professor of Psychology at Florida State University, has been a pioneer in researching deliberate practice and what it means. According to Ericsson:

"People believe that because expert performance is qualitatively different from normal performance the expert performer must be endowed with characteristics qualitatively different from those of normal adults." "We agree that expert performance is qualitatively different from normal performance and even that expert performers have characteristics and abilities that are qualitatively different from or at least outside the range of those of normal adults. However, we deny that these differences are immutable, that is, due to innate talent. Only a few exceptions, most notably height, are genetically prescribed. Instead, we argue that the differences between expert performers and normal adults reflect a life-long period of deliberate effort to improve performance in a specific domain."

One of Ericsson's core findings is that how expert one becomes at a skill has more to do with how one practices than with merely performing a skill a large number of times. An expert breaks down the skills that are required to be expert and focuses on improving those skill chunks during practice or day-to-day activities, often paired with immediate coaching feedback. Another important feature of deliberate practice lies in continually practising a skill at more challenging levels with the intention of mastering it.[4] Deliberate practice is also discussed in the books, "Talent is Overrated," by Geoff Colvin,[5] and "The Talent Code," by Daniel Coyle,[6] among others.

Points to Ponder

Ezra Klein:

In their ambition to simultaneously reformulate almost every major government program, Republicans have embraced an agenda of greater complexity and scope than anything Democrats now promote. An America in which the federal government can successfully run Medicaid but can’t build functional exchanges has no place for Ryan’s far-reaching reforms.

One of the advantages of simple and universal programs is that they are easy to administer.  When you have a country of 300 million people, it is not trivial to figure out who is entitled to benefits. 

Ironically, the sort of reforms where we match people more precisely to benefits are precisely the reforms that require really good government in order to work. 

Kennedy, Camelot and the danger of myth

"I just can't see a picture of Martin Luther King without thinking, you know, that man's terrible."
Jacqueline Kennedy, speaking in the months after her husband's assassination.

Over at the Monkey Cage, there's a political science take on the anniversary of the assassination (Why so many Americans believe Kennedy assassination conspiracy theories). It makes some interesting points but I have a somewhat different take.

As we've talked about before, if there's an idea that fits in with pre-existing beliefs (particularly one which alleviates cognitive dissonance) and which is aesthetically attractive, people will tend to favor that idea over better supported but less appealing alternatives.

The Sixties are a period that inspire intensely conflicting emotions, particularly among boomers, often producing great cognitive dissonance and there is probably no more resonant myth than that of a lost golden age (with loss due to betrayal being a particularly popular variant). In the case of John F. Kennedy, the Camelot allusions started almost immediately after the assassination and Johnson was soon identified with one of the most mythic of betrayers. (The use of conspiracy theories to delegitimize presidencies is, of course, not limited to LBJ.)

The power of these loss myths obviously rely on the counterfactual leading to a happy place. (if Orpheus and Eurydice were headed for a miserable marriage, the story isn't nearly as effective.) In the case of JFK, for many Democrats and boomers (particularly boomers who had been draft eligible), this basically means the great society without the escalation in Vietnam.

As for the latter, there is certainly evidence that Kennedy was seriously considering getting out, having come to suspect that the war was a lost cause, but every president from Ike through Nixon saw Vietnam as problematic, but every administration got us in deeper. Wars have a long history of being easier to get into than out of. Add to that JFK's commitment to fighting communism (particularly in Latin America and, because nothing ever changes, Iraq) and you can see how certain historians take this position:

Patricia Limerick, a University of Colorado history professor who heads the school's Center of the American West, doubts Kennedy would have backed off from U.S. involvement in Vietnam. The policy of communist containment was too ingrained in him.

"That was one Cold Warrior, that Kennedy," Limerick said. "He gave so much momentum to Vietnam. Cold War thinking was such a powerful arranger of brain cells of people of a certain age at that time."

The domino theory — the notion that communist expansion would continue unless directly confronted — drove decisions. Even the race to the moon was a direct competition with the Soviet Union.

"So I don't know any reason to think that foreign policy would have evolved," Limerick said. "Lyndon Johnson inherited a rat's nest, and we all know who he inherited it from."

How about domestic (and extraterrestrial) policy? Kennedy had laid out an ambitious "New Frontier" agenda but outside of research the progress had struck many observers at the time as somewhat slow, particularly on the social justice side. It's not entirely clear why that would have changed. Even when it came to Apollo, Johnson had been pushing the space race as early as the late Fifties and was, if anything, more dedicated to the issue than was Kennedy.

Of course, the cause where the difference is sharpest is civil rights. While Kennedy was certainly progressive on these issues, they were not a priority. Furthermore, there was considerable emotional distance between the Kennedys and the leaders of the civil rights movement, most notably Martin Luther King who was not even invited to JFK's funeral.

By comparison:

By this time in January 1965, Johnson had already driven through Congress the most important civil rights legislation since emancipation. Now, he told King, their work was only beginning. When Congress reconvened, he intended to introduce a voting rights bill, one that would bring justice to the segregated South, creating a vast new pool of loyal Democratic voters even as it would surely alienate multitudes of whites. ''The president and the civil rights leader -- the politician and the preacher -- were bouncing ideas off each other like two old allies in a campaign strategy huddle, excited about achieving their dreams for a more just society,'' Nick Kotz writes in his narrative history of the two men's alliance. ''As always,'' he continues, ''Johnson did most of the talking. As always, King was polite and deferential to the new president. But there was a shared sense of new possibilities, new opportunities for cooperation to bring about historic change.'' This carefully etched scene serves complementary purposes. It captures Johnson and King at the apex of their collaboration, a snapshot of an optimistic peak that only magnifies the friction and tragedy to come.

The standard response to the Kennedy-King antipathy has generally been to blame J. Edgar Hoover ("Caroline Kennedy, the daughter of John and Jacqueline, said her mother's comments about King are evidence of the 'poisonous' activities Hoover was engaged in, as he ruled the FBI as his private fiefdom."), but as appealing as this is from a psychological standpoint (the "bad council" excuse is often used to alleviate cognitive dissonance), there are at least a couple of problems with this explanation.

For starters, Hoover had constructed his empire in large part by being able to sense both what presidents needed to know and wanted to hear. Here's Tim Weiner, author of "Enemies: A History of the FBI."

GROSS: So did Hoover kind of make a lifelong practice of using his wiretapping to spy on people he perceived as his enemies in government?

WEINER: Well, that's correct, but he also was very well-attuned to what presidents wanted to hear. President Eisenhower wanted to hear about the communist threat. President Johnson wanted to know about the Ku Klux Klan, and despite his lifelong predilection for opposing integration, Hoover did as the president ordered. He was very sensitive to the needs of presidents.

More importantly, Johnson had heard the same FBI reports that Kennedy had but they had no apparent effect on his attitude toward King, though they may have shaped his feeling toward Hoover. ("It's probably better to have him inside the tent pissing out, than outside the tent pissing in.")

In other words, the golden age story here assumes that Kennedy was about to change direction on the two defining issues of the decade -- Vietnam and civil rights -- and that he was going to change in the right direction (right according to the belief system of those who tend to hold most tightly to the Camelot myth). This could well have happened during a second Kennedy term. Or we could have had withdrawal from Vietnam but no Head Start, Medicare, Medicaid, or Voting Rights Act. We might have even stayed in Vietnam and lost all of those programs.

Myths of golden ages and the loss of innocence are tremendously appealing in large part because they let us avoid facing the way things really are. With all due respect to JFK (who was, in many ways a great man), maybe it's time to let this one go.

Students will little note, nor long remember what was taught here...

[Update: For more on Common Core and David Coleman check out this follow-up post, "The great pedagogical end run"]

It was just over one hundred and fifty years ago that Abraham Lincoln delivered the Gettysburg Address. That makes this story from Valerie Strauss particularly timely:

Common Core’s odd approach to teaching Gettysburg Address

Imagine learning about the Gettysburg Address without a mention of the Civil War, the Battle of Gettysburg, or why President Abraham Lincoln had traveled to Pennsylvania to make the speech. That’s the way a Common Core State Standards “exemplar for instruction” — from a company founded by three main Core authors — says it should be taught to ninth and 10th graders.

The unit — “A Close Reading of Lincoln’s Gettysburg Address“ — is designed for students to do a “close reading” of the address “with text-dependent questions” — but without historical context. Teachers are given a detailed 29-page script of how to teach the unit, with the following explanation:

The idea here is to plunge students into an independent encounter with this short text. Refrain from giving background context or substantial instructional guidance at the outset. It may make sense to notify students that the short text is thought to be difficult and they are not expected to understand it fully on a first reading — that they can expect to struggle. Some students may be frustrated, but all students need practice in doing their best to stay with something they do not initially understand. This close reading approach forces students to rely exclusively on the text instead of privileging background knowledge, and levels the playing field for all students as they seek to comprehend Lincoln’s address.

The Gettysburg Address unit can be found on the Web site of Student Achievement Partners, a nonprofit organization founded by three people described as “lead authors of the Common Core State Standards.” They are David Coleman,  now president of the College Board who worked on the English Language Arts standards; Jason Zimba, who worked on the math standards; and Susan Pimental, who worked on the ELA standards. The organization’s Linked In biography also describes the three as the “lead writers of the Common Core State Standards.”

At the risk of deviating from the standards of close reading, this requires some context. The education reform movement, like all major movements, is an alliance between different groups with different agendas. One of the less recognized of these groups is well-intentioned educators who champion certain pedagogical theories that have proven to be hard sells. (David Coleman is, in many ways, the archetypal member of this group.) The reform movement's emphasis on standardization (note the 29-page script) has given them a chance to apply these theories on a massive scale without a lot of review and despite a lot of resistance.

This resistance is a major but largely unreported source of tension between movement reformers and teachers (particularly experienced and, ironically, effective teachers) who are reluctant to scrap proven approaches for ideas that can, frankly, sound a bit flaky. More on that later.

This post continues the Common Core thread that started here. It also relates to some of my earlier comments about rutabaga cults.

More Motley Foolishness -- Hydrogen is safe as a fuel, not as an investment

I spotted another doozy from Motley Fool. For a change, it doesn't involve Netflix or Disney, but other than that the formula is basically the same and the advice is, if anything, worse. As is often the case, the title gives you a good idea what to expect:

"Will This New Toyota Hydrogen Car Change the World?"

The story, by John Rosevear, is pretty much a retyped press release along with some standard pop science boilerplate on hydrogen fuel cells all delivered in MF's typical breathless style ("heavy bets on fuel cells — and hydrogen — as a way to power the automobiles of the future"). As always, MF is careful not to come out and say that this is the next big thing while being just as careful to downplay (or omit entirely) all the troubling facts that undercut their argument.

There's an old saying in military circles that goes "Amateurs talk strategy; Professionals talk logistics." When dealing with transportation technology, you might replace 'strategy' with 'features' and 'logistics' with 'infrastructure.' Transportation infrastructure often faces a nasty chicken/egg problem -- few people want to buy the vehicles until the infrastructure is in place and you can't get infrastructure funded until lots of people own the vehicles -- but with hydrogen fuel cell cars the problem is particularly acute. Not only is hydrogen somewhat difficult to handle, it is competing against a range of low and zero emission vehicles, all of which use well-established infrastructure. There is no county in America where you cannot get gasoline, diesel, natural gas, and electricity.

On top of that, you also have a serious concern about energy density. There simply is not that much power you can extract from a cubic foot of hydrogen, even under considerable pressure.Gasoline has excellent energy density. Diesel is even better. Batteries are constantly improving. With hydrogen, I don't see much room for improvement. Energy density isn't as much of a problem with stationary systems but if you have to carry your fuel around with you it's a big deal. The FCV has "two spun-carbon and aluminium tanks holding hydrogen gas pressurised to 700 bar (10,000psi)" for decent range. That's a solid piece of engineering by Toyota (which employs a lot of smart people) but you have to suspect that higher pressures will be very hard to come by.

I don't want to paint too grim a picture. It's possible that Toyota's FCV will lead to something major -- there could be an unexpected technological advance or a major government initiative that subsidizes both the cars and their infrastructure -- but based on current comparative functionality and infrastructure issues, this technology is very much a long shot.

More to the point, the challenges facing fuel cell vehicles are widely known and if you're reading something about investing in this sector, these challenges need to be prominently mentioned very near the top of the page. If they aren't, you need to ask yourself how much value to put on the writer's advice.

Pre-existing conditions

Mark Palko sent me a link to a Consumer Reports discussion of pre-ACA individual market healthcare.  It was scathing, giving examples like:

The Georgia real estate agent whose group health plan was folding and who couldn’t find replacement insurance unless it excluded coverage of her $1,700-a-month rheumatoid arthritis medication, without which she would quickly become disabled.

I think that the example above gives a good example of what makes the market in health insurance challenging.  When you link your insurance to your job, some people will inevitably lose their jobs.  These people will have paid into insurance when they were healthy but no longer have access to that plan.  Thus they have serious problems ever getting coverage.

Now this would be fine if acute risks were all that we were insuring against (like a house fire).  But we also insure against the development of a chronic condition that is expensive to treat and ongoing.  Now add in recission -- health plans checking to see if you gave perfectly accurate information only after you start claiming benefits (notice that they do not offer to return previously paid premiums as part of this process) and it is clear that the individual health plan market had some serious drawbacks.  In fact, given recission, it is unclear if people who lose inexpensive plans were actually insured in the case of a disaster. 

Now the private market solution to this set of problems is a regulated series of exchanges.  If these exchanges cannot be made to work, and even private companies seem to have trouble with doing so from time to time, the next best solution would be to expand public coverage.  What if anybody could opt-in to Medicaid?  Would that really be a disaster?  It would hurt medical wages and simultaneously expand demand, but we could compensate by expanding medical licensing to groups like Nurse Practitioners provide care to Medicaid patients.  Then private insurance is supplemental (like the UK) and these issues become a lot less concerning (because insurance reputation begins to really matter). 

These issues are worth keeping in mind as we watch this experiment unfold.
