Get Alfie Kohn on the Phone!

February 13, 2009

According to research published last week in the New England Journal of Medicine, smokers who were offered financial incentives to quit smoking were more likely to do so.  As the Wall Street Journal describes it:

“For the new study, researchers, led by a team from the University of Pennsylvania, tracked 878 General Electric Co. employees from around the country for a year and a half in 2005 and 2006. Participants, who smoked an average of one pack of cigarettes a day, were divided into two groups of roughly equal size. All received information about smoking-cessation programs.

Members of one group also got as much as $750 in cash, with the payments spread out over time to encourage longer-term abstinence. Those participants got $100 for completing a smoking-cessation program, $250 if they stopped smoking within six months after enrolling in the study, and $400 for continuing to abstain from smoking for an additional six months.

All participants were contacted three months after they enrolled in the study and periodically after that. Those who said they had stopped smoking at any point during the study were asked to submit saliva or urine samples for testing so that their claims could be verified.

About 14.7% of the group offered financial incentives said they had stopped smoking within the first year of the study, compared with 5% of the other group. At the time of their last interview for the 18-month study, 9.4% of the paid group was still abstaining compared with 3.6% of those who got no money.”

Wait a minute!  If I’ve learned one thing from Alfie Kohn it is that extrinsic rewards undermine intrinsic motivation.  The smokers paid to stop should have had the internal motivation to quit undermined and should have been less successful than those who quit for the pure joy of it.

I’ve got an idea.  Let’s stop paying people for their work because it only undermines their internal motivation to work.  And to avoid undermining Alfie Kohn’s motivation, I’m sure he’d understand if people stopped paying him for his lectures and books.


Research Round-Up

February 10, 2009

The U.S. Department of Education released a study on how alternatively certified teachers affect student achievement.  The bottom line is that they find: “students of teachers who chose to enter teaching through an alternative route did not perform statistically different from students of teachers who chose a traditional route to teaching.  This finding was the same for those programs that required comparatively many as well as few hours of coursework. However, among those alternative route teachers who reported taking coursework while teaching, their students performed lower than their traditional counterparts.” 

I’m sure that the headlines will be:  “Alternative Certification Fails to Improve Student Achievement.”  But they will have it backwards.  The real headline should be: “Years of Teacher Education Coursework Yields No Benefits for Student Achievement.”

Besides, the real question is whether the alternatively certified teachers are better than the traditional certified teachers districts would have hired if they were constrained to hire only certified teachers.

And in other research news, the forthcoming issue of Education Next has an article by Paul Peterson and Matthew Chingos comparing student achievement in Philadelphia’s for-profit managed schools versus district-managed schools.  The find: “the effect of for-profit management of schools is positive relative to district schools, with math impacts being statistically significant. Over the last six years, students learned each year an average of 25 percent of a standard deviation more in math — roughly 60 percent of a year’s worth of learning — than they would have had the school been under district management. In reading, the estimated average annual impact of for-profit management is a positive 10 percent of a standard deviation — approximately 36 percent of a year’s worth of reading. Only the math differences are statistically significant, however.”


What is Required to be Part of the Black Caucus?

February 10, 2009

This story comes out of the Arkansas Democrat Gazette.  I think it raises all sorts of interesting questions about identity politics, but I don’t have the answers.  So, I’ll just reproduce portions below to see what folks think.

“Rep. Richard Carroll of North Little Rock, Arkansas’ only Green Party legislator, asked to be a member of the Arkansas Black Legislative Caucus but was rejected because he’s white….  Asked about it after the meeting, Carroll said he wanted to be a member, but that caucus leaders told him that caucus bylaws require that members be black.

Caucus Chairman Rep. Nancy Duffy Blount, D-Marianna, likened the situation to a man wanting to be part of the Legislative Women’s Caucus. ‘With men, there are some things that men can understand and share and there are some things they can’t because they’re not women,’ Blount said. ‘Same thing here…’

Carroll, 52, said he wanted to be a caucus member to better represent and understand the views of his constituents. He said he could ask his wife, who is black, for her thoughts, but that she would only be one person.

‘You have to be an elected legislator and you have to be black,’ Blount said…. The latest bylaws for the caucus on file at the Bureau of Legislative Research give no race requirement for membership. It says that the membership ‘shall consist of any current member of the Arkansas General Assembly who pays an annual membership.’ But the bureau staff didn’t know whether those bylaws were current. Blount said she didn’t know either but she thought they had been changed to include a race requirement. She said she doesn’t have a copy of the bylaws but based her understanding of the membership requirements on ‘common sense’ and from what caucus vice chairman, Sen. Tracy Steele, D-North Little Rock, told her the bylaws said. Steele later said he had ‘no idea’ what the bylaws said about membership. …

Carroll wondered how the caucus ‘defines black,’ whether you needed to be a ‘certain percentage’ black. Blount said, ‘If you say you are an African-American, we don’t go back and do a historical search. We just go on whatever they say they are.’

Another caucus member, Sen. Joyce Elliott, D-Little Rock, said Carroll’s interest in the caucus is ‘commendable’ but ‘since it’s called the ‘black caucus’ he can’t be a member. It is a caucus defined as being black. All discrimination is not bad. You can discriminate about whether you are going to drink four beers or 10 beers. I would say that’s good discrimination. “‘ Elliott said excluding whites is a legitimate form of discrimination because black legislators need to join with others of ‘common cause.’

Carroll said he didn’t see it as a discrimination either.  ‘It’s just that that’s their bylaws,’ he said.

It’s only a matter of time until there is a dispute over membership in the Gay Caucus.  How will we tell?


You Mean Wal-Mart Isn’t Evil?

February 9, 2009

 

(Don’t blame me for the lousy photo-shopping.  Eduwonkette did it.  But I told her it made me look like David Byrne in his giant suit.  Pretty cool!)

David Kinkade at the Arkansas Project alerted us to this piece by Charles Platt, a writer at Wired Magazine, on his experience going “undercover” to work for Wal-Mart.  Platt writes:

” I found myself reaching an inescapable conclusion. Low wages are not a Wal-Mart problem. They are an industry-wide problem, afflicting all unskilled entry-level jobs, and the reason should be obvious.

In our free-enterprise system, employees are valued largely in terms of what they can do. This is why teenagers fresh out of high school often go to vocational training institutes to become auto mechanics or electricians. They understand a basic principle that seems to elude social commentators, politicians and union organizers. If you want better pay, you need to learn skills that are in demand.

The blunt tools of legislation or union power can force a corporation to pay higher wages, but if employees don’t create an equal amount of additional value, there’s no net gain. All other factors remaining equal, the store will have to charge higher prices for its merchandise, and its competitive position will suffer.

This is Economics 101, but no one wants to believe it, because it tells us that a legislative or unionized quick-fix is not going to work in the long term. If you want people to be wealthier, they have to create additional wealth.

To my mind, the real scandal is not that a large corporation doesn’t pay people more. The scandal is that so many people have so little economic value. Despite (or because of) a free public school system, millions of teenagers enter the work force without marketable skills. So why would anyone expect them to be well paid?

In fact, the deal at Wal-Mart is better than at many other employers. The company states that its regular full-time hourly associates in the US average $10.86 per hour, while the mean hourly wage for retail sales associates in department stores generally is $8.67. The federal minimum wage is $6.55 per hour. Also every Wal-Mart employee gets a 10% store discount, while an additional 4% of wages go into profit-sharing and 401(k) plans.”

He then concludes:

“Based on my experience (admittedly, only at one location) I reached a conclusion which is utterly opposed to almost everything ever written about Wal-Mart. I came to regard it as one of the all-time enlightened American employers, right up there with IBM in the 1960s.”

So, the path to higher worker wages is improved education, not unionization?  Luckily the unions do so much to help improve education that I guess we are in great shape!


Mistaken AJC Voucher Editorial Held Accountable

February 9, 2009

 

One of the great things about these here inter-web thingies is their ability to hold newspapers accountable when they make mistakes.  And the editorial by Maureen Downey that the Atlanta Journal Constitution ran last week on vouchers was very much mistaken.  In it Downey  claimed “in the handful of states that have conducted experiments with vouchers, the results contradict claims of improvement by Johnson and other voucher advocates… Yet, in return for zero impact, Johnson proposes to dismantle public education in Georgia.”  She also described “vouchers as a threat to the bedrock American belief that public education is critical to the health of the democracy and should not be sacrificed to political agendas.” 

To support her overwrought claims she cites a newspaper article on Ohio’s voucher program, studies of the voucher programs in DC and Milwaukee conducted by my colleague Pat  Wolf, and a review of the literature by Barrow and Rouse.  Unfortunately she cites all of them selectively or misinterprets their findings as showing “zero impact.”  Fortunately, Pat Wolf noticed her incorrect interpretation of his work and sent a letter, which the AJC ran today.

But letters are limited in length and less salient than the editorials they attempt to correct.  In the old days when newspapers were the only game in town, it was very difficult to hold newspapers accountable for editorials that were factually inaccurate.  They might have run letters, like the one Pat Wolf submitted, but they wouldn’t even have to do that if they didn’t want to.

With the inter-webs we not only have Pat Wolf’s letter in the AJC, we can also circulate it by posting it on blogs, like I just did.  And we can add additional material, for which there would have been no space in the letters section.  So let me add that here is a complete list of random-assignment studies of the effects of vouchers on students who use themHere is a summary of the effect of vouchers on the public school system.  And here is random-assignment research on the effect of charter schools on participants.  And if she thinks choice destroys democracy, here is a review of that literature showing that she is mistaken about that as well.

If Maureen Downey and the Atlanta Journal Constitution want to say that evidence shows “zero impact” from vouchers, then they have to explain away all of this evidence.  And if they don’t want to justify their claims in the pages of their paper, we can hold them accountable on the web.

Get Lost 9

February 6, 2009

(Spoiler Alert!)

Another great episode, but not too much new was revealed that could not have already been guessed. 

1) Jin is alive, but not having seen him die, we could have guessed that he’d be back.  In addition, having him alive will make Sun’s efforts at revenge more tragic. 

2) Miles has been on the island before and is probably Pierre Chang’s (Marvin Candle’s) son, who was the baby we saw with him when the record skipped in the season opener. 

3) Ben was the one sending lawyers to take Aaron from Kate, probably to push her into returning with Aaron to the island to keep him.

The introduction of younger Danielle and the French scientists suggests that much of this season will be consumed with “back-filling” the plot.  That is, we are going to fill in the story of how various, previously minor, characters are actually significant parts of the plot in the past.  Now that we’ve seen the younger Widmore and the younger Danielle, I bet we are going to learn about how Widmore was forced from the island and why some are allied with him and some with Ben.

I’m also pretty sure that “Ellie,” the woman who held Daniel Faraday at gunpoint as he went to dismantle “Jughead,” the H-bomb, is a younger Ms. Hawking.  And Ms. Hawking is Daniel Faraday’s mom.  You can see the evidence for this theory here.

I think Lost will be governed by Terminator Rules, where the future cannot be changed despite efforts to do so.  And with an H-bomb on the island I fear that the end is that the island is destroyed by it.  People are trying to “save the island” by changing time, but it will be doomed.  And we’ll have one big time loop where “Adam and Eve” (who may be Aaron and Ji Yeon, Sun and Jin’s baby) loop back to the start of the island in time from near it’s end.

I do have some questions about Jin and Danielle.  Had they met in the future?  If so, did Danielle remember that she had met Jin in the past?  Is it possible that we aren’t playing by Terminator Rules and Jin’s encounter with Danielle in the past is something that didn’t happen previously?  Has the string of time been changed?

Also, Brian has suggested a theory that the water bottle in the canoe is going to be very significant.  Perhaps the people in the canoe are members of the Oceanic 6 unknowingly (?) shooting at their former fellow castaways.  Or maybe they are intentionally doing so to stop them from something horrible that they are about to do.  As we back-fill we are going to see these same episodes from different perspectives.


The Wagner Epic Continues

February 3, 2009

No, not that Wagner.  There is more on Tony Wagner, the snake-oil salesman educational consultant.  My op-ed on Wagner ran in the Northwest Arkansas Morning News.  I’ve also reprinted the text below, since it is easier to read that than the scanned pdf in the link.

The first community discussion on Wagner’s book, The Global Achievement Gap, was held last nightIt wasn’t too bad.  A number of teachers (at tables other than mine) expressed resentment at the suggestion that they weren’t already aware that critical thinking and creativity were desirable.  But administrators and GT teachers seemed more enamored with the book.  And the reaction from parents and community members included a fair degree of skepticism. 

It’s hard to get people to think critically about people who push a focus on critical thinking.  To be for critical thinking is like being for goodness and light.  The tricky part is in how you get there.  To the extent that Wagner has any concrete suggestions, he seems to be taking folks down the wrong path.  He wants less emphasis on content and less testing.  But he shows no evidence that higher levels of critical thinking can be found in places or at times when there was less content and less testing.  In fact, the little evidence he does provide would suggest the opposite.

Some smart folks are pushing back against these data-free educational consultants.  Sandra Stotsky had an op-ed on Wagner last weekDan Willingham had an excllent blog post on Alfie Kohn as did Stuart Buck.  And Robert Pondiscio at Core Knowledge ,  AndyRotherham at Eduwonk , and Ken De Rosa at D-Ed Reckoning have added their two cents (which, with the new stimulus package, will become 2 trillion cents).

So here is my op-ed pasted below:

Fayetteville Public Schools Need Evidence, Not Snake-Oil (submitted title)
By Jay P. Greene

              The Fayetteville Public Schools purchased 2,000 copies of Tony Wagner’s The Global Achievement Gap and organized a series of public fora to discuss how that book might guide our schools.  The District is to be commended for engaging the community in this process.  But it is unclear why the District selected Wagner’s book as the focus of this discussion.

Wagner’s book makes claims about what skills students really need to learn, what is blocking them from learning those skills, what countries are more successful in teaching these skills, and what some schools are doing to remedy the problem.  But he provides no systematic evidence to substantiate any one of these claims.  In short, the book is a series of anecdotes that more closely resembles what one would find in a self-help manual than in a work of social science.  If we apply our critical thinking skills, which Wagner says are essential, we should reject this book as a sound basis for planning the future of Fayetteville schools.

First, Wagner says there are seven essential survival skills that our children need to learn.  How does he know that these are the essential skills?  He chatted with a CEO on an airplane and selected a few more to interview.  Does he review any research on the types of skills that predict who will become successful adults?  No. Wagner relies upon the authority of his experience and the experiences of a handful of corporate executives to identify the essential skills.  Accepting claims on this basis would be the sort of thing we would hope people with critical thinking skills might reject.

Frankly, the seven skills he lists — critical thinking, collaboration, adaptability, initiative, communication, analysis, and imagination – seem reasonable enough, but they are also so vague as to be unhelpful in informing schools about what to do.  How exactly do we produce critical thinking or adaptability or creativity?  It’s not as if educators have been unaware of these goals, but they haven’t generally been effective at developing strategies to achieve them.

Then Wagner identifies what he believes is blocking the acquisition of these seven essential skills – high stakes testing.  What evidence does he present to support this claim?  Again, he presents no systematic evidence to demonstrate that there is a tradeoff between the content knowledge required in accountability testing and the essential skills he wants.  Couldn’t it be the case that improving mastery of basic skills and content knowledge provides the foundation for these seven skills?  It’s hard to be imaginative, analytical, etc… without knowing subject matter and basic skills of literacy and numeracy.  Einstein may have said “imagination is more important than knowledge,” as the book’s dedication indicates, but Einstein couldn’t have succeeded without a firm grasp of advanced mathematics.

If Wagner were right that accountability testing undermines essential skills, then surely these skills must have been more plentiful before testing became as salient as it is today.  But Wagner does not (and cannot) provide any evidence to show that.  Instead, he shows (on p. 74) that students in the United States significantly lag students in Finland, Hong Kong-China, Japan, and Korea in certain problem solving skills on an international test called PISA.  As it turns out, high stakes testing is extremely prominent in most of these countries with strong problem-solving results – a fact curiously at odds with Wagner’s claims.  If accountability testing undermines essential skills, why do countries with such strong accountability systems manage to succeed so well in teaching the essential skills Wagner wants?

Wagner describes three model schools that he says have been effective at teaching essential skills (although he again fails to provide any evidence that they are as successful as he claims).  But it is by no means clear that the approaches adopted by these three schools are the only valid approaches or that they could be replicated easily by others.  Replication is especially problematic because the three models he provides are all charter schools or alternative schools of choice.  Perhaps the secret of these schools’ success has something to do with school choice and not the features he describes.  If true, it’s not clear how Fayetteville could imitate the success of these schools.

To achieve our goals in education we have to adopt approaches backed by systematic evidence.  If we believe critical thinking, collaboration, and creativity are the most important goals for schools, then we need systematic evidence on systems of teacher preparation, curriculum, and pedagogy that effectively produce those goals.  There is a growing body of scientific research on these issues, including a number of studies sponsored by the U.S. Department of Education’s Institute for Education Sciences, that the Fayetteville Public Schools might wish to consider rather than consulting with the latest peddler of educational snake-oil.


Building Without Foundation of Evidence

February 1, 2009

This is the model for new school construction. (HT: Arkansas Project)

 I understand why House Democrats included $20 billion for school construction in the $819 billion stimulus package they passed last week.  They need to throw money out the window as fast as the printing presses can make it.  That way they can say they are doing something to “help” the economy.  And as long as they are doing something they might as well help their friends in the educational industrial complex.

What I don’t understand is why some normally smart people feel compelled to justify this school construction spending by claiming that it will help students or that it is badly needed.  There is no evidence to support these claims.  That’s why I was surprised to see Sara Mead, senior research fellow at the New America Foundation, write:

“But perhaps the most important reason to invest in school construction is that our students need it. Just as Americans have underinvested in our bridges, roads, and other infrastructure, we’ve also underinvested in our education infrastructure. The American Society of Civil Engineers Infrastructure report card gives our school buildings a grade of D — lower than grades for bridges, rail, or public transit infrastructure. According to the National Center for Education Statistics, it would cost $127 billion just to renovate and repair crumbling or outdated school facilities to good condition. Poor school facilities don’t necessarily prevent students from learning, but, it’s unconscionable that we currently ask students to learn, and teachers to work, in buildings that are overcrowded, inadequately heated and ventilated, poorly maintained, and in some cases literally falling apart. The contrast between schools and other buildings sends our most disadvantaged children a devastating message about the value we place on their education.”

As readers of JPGB may recall, the research literature finds no relationship between school facilities and student achievement (outside of developing countries, where a grass hut and mud floor may be a hindrance in bad weather).  To repeat: “In the Handbook of the Economics of Education, Eric Hanushek reviews all of the research meeting minimal quality standards regarding the relationship between school facilities and student performance.  He identifies 91 analyses on the issue in the U.S. and finds that 86% of them show no statistically significant relationship.  Of the remaining 14% of analyses that did show significant effects, 9% were positive and 5% were negative. ”

If the evidence generally fails to find that better school facilities improve student outcomes, it’s not clear how Sara Mead can support claims like “our students need it” or that current facilities send “a devastating message about the value we place on their education.”  If it has no effect on their learning, how devastating could it be?

Perhaps Sara Mead relies upon the assessments from the American Society of Civil Engineers (ASCE) and the National Center for Education Statistics (NCES) to support her claims.  Let’s look into those references a little further to see whether we should believe them or believe the research reviewed by Rick Hanushek.

The ASCE grade of D-  for school infrastructure is in a report card issued by the interest group representing engineers who design public infrastructureTo determine the grades ASCE “assembled a panel of 24 of the nation’s leading civil engineers” who then reviewed other reports and surveys of civil engineers.  I would be more specific about their methodology, but they provide almost no information about their methods or standards.  Their entire description of the methodology consists of 5 sentences.  You can read it yourself to see.

In the 2009 report card they actually gave school infrastructure a D.  But don’t worry, that is the average grade they gave to the 15 categories of public infrastructure they graded, which ranged from C+ to D -.  They also determined that we need to spend $2.2 trillion (with a T!) on public infrastructure.  How exactly did they determine that?  Again, the five sentences describing their methodology didn’t exactly explain all that.  But since they are a lobby group representing engineers who work on public infrastructure projects, I’m sure we can just trust their expert judgment that we urgently need to spend $2.2 trillion on what they do.

Using the NCES to support a need for $127 billion in school construction spending is hardly more persuasive.  To be precise, the NCES did not determine the amount that needs to be spent on schools.  They just surveyed school district officials and in the survey asked the school officials how much money they thought needed to be spent on their schools to bring them to “good” condition.  The NCES does not represent this result as their own opinion; they portray it as the opinion of the people they surveyed.

Again, asking people who are the potential beneficiaries of public spending whether they need more money without any standards to define their “need” is unlikely to be a reliable method. 

To illustrate the point, I’ve conducted a survey of “experts” on JPGB – the regular contributors — to determine the resources we would need from the federal bailout to bring the blog “into good overall condition.”  One respondent identified the need for martinis, cigars, and a few Vegas junkets to improve our creative process.  Another identified the need for a board game marathon only interrupted by Indian food buffet binges to sharpen our intellect.  And another agreed with the first two and added  the need for a spaceship, pony, and a lifetime supply of spicy wings and candy.  (You can guess who’s who.)

I think I’m going to trust Hanushek’s assessment of 91 analyses that meet social science standards over the self-serving assessments of school officials and and a construction lobbying organization.  If you disagree, then I expect that you’ll support our demands to add JPGB to the bailout since, after all, the “evidence” clearly demonstrates our need.

Fayetteville has been hit by an incredible ice storm that has knocked us out of commission.  Above is a photo taken by Brian Kisida of his street near the university.  Everyone should appreciate power and heat while they have it.


Critical Thinking About Critical Thinking

January 27, 2009

snakeoil553.jpg

Fayetteville Public Schools have been hypnotized by Tony Wagner’s The Global Achievement Gap.  They’ve bought 2,000 copies, which they’ve distributed to administrators, teachers, and members of the community.  They’ve organized three public discussions of the book.  They are bringing in Wagner himself.  And they’ve indicated that they would like to use this book as a guide for planning a new high school and other changes.

My colleague, Sandra Stotsky, applies her critical thinking skills in today’s Northwest Arkansas Times to Wagner’s call for more emphasis on “21st Century Skills,” like critical thinking, adaptability, and creativity, and less emphasis on subject content:

“Who can argue against teaching students ‘agility and adaptability’ or how to ‘ask good questions?’ Yet these ‘skills’ are largely unsupported by actual scientific research. Wagner presents nothing to justify his list except glib language and a virtually endless string of anecdotes about his conversations with high-tech CEOs.

Even where Wagner does use research, it’s not clear that we can trust what he reports as fact. On page 92, to discredit attempts to increase the number of high school students studying algebra and advanced mathematics courses, he refers to a ‘study’ of MIT graduates that he claims found only a few mentioning anything ‘more than arithmetic, statistics and probability’ as useful to their work. Curious, I checked out the ‘study’ using the URL provided in an end note for Chapter 3. It consisted of 17, yes 17, MIT graduates, and, according to my count, 11 of the 17 explicitly mentioned linear algebra, trig, proofs and/ or calculus, or other advanced mathematics courses as vital to their work – exactly the opposite of what Wagner reports! Perhaps exposure to higher mathematics is not the worst problem facing American students!

Similarly, while I agree with Wagner that too many public schools fail to teach ‘effective oral and written communication,’ I am utterly puzzled by his contention that teachers’ obsessions with teaching grammar, test-prep and teaching to ‘the test’ are the problem. Really? Which English teachers? A lot of parents would kill to get their children into a classroom where they knew the teacher cared about grammar, or at least was brave enough to try to teach conventional sentence structure and language usage.

As for too much testing in schools, another of his complaints, Wagner again cites no relevant research. On the other hand my colleague Gary Ritter finds that here in Arkansas public schools the most tested students – those in grades five and seven – spend only 1 percent of total instructional time being tested, probably less time than spent in class parties or on field trips. And without testing, how can we figure out what our students know, and which programs successfully teach them?

Wagner’s book is engaging and sometimes points to real defects in American schools. Yet it fails to use research objectively to ascertain what is truly happening in America’s 90,000 public schools. Moreover, like all too many education ‘reformers’ Wagner is simply hostile to academic content. Wagner does not seem to care if students can read and write grammatically, do math or know something about science and history – real subjects that schools can teach and policy-makers can measure.

Unfortunately, Wagner dismisses measurable academic content while embracing buzzwords like ‘adaptability’ and ‘curiosity,’ which no one could possibly be against, but also which no one could possibly measure. Do we really care if our students are curious and adaptable if they cannot read and write their own names? “

I have my own op-ed on Wagner pending at another local paper.  Meanwhile my colleague Stuart Buck has an excellent blog post on a related topic — Alfie Kohn’s attack on Core Knowledge.  Even worse, Stuart notes, Kohn accuses people who disagree with him of having bad intentions and not just being mistaken.

It is puzzling how this entire industry of education consultants, including Wagner, Kohn, Kozol, and Gardner, manage to have such large followings with such weak arguments.
