Being Misquoted

July 17, 2008

Dean Millot has a new post attacking me on the peer review issue that Eduwonkette promotes on her own site.

But Dean Millot is being fundamentally dishonest in that he misquotes me. He says that I argue: “In short, I see no problem with research becoming public with little or no review.”

In fact I wrote: “In short, I see no problem with research initially becoming public with little or no review.” (See here )

The absence of the word “initially” makes quite a difference and sets up the straw man that Millot wishes to knock down. The issue is not whether research can benefit from peer review, but whether it is inappropriate to make it publicly available INITIALLY, before it has received peer review.

Readers may want to wonder about the credibility of Millot’s claim that “One of the reasons I do my best to quote the very words of people I write about in edbizbuzz is that I prefer to fight fair.”

And so much for Eduwonkette’s praise of Millot’s “measured, careful, and thoughtful analysis.”

I’m waiting for the correction and apology from both of them.


It Never Ends

July 14, 2008

I thought that the exchange with Eduwonkette over the appropriateness of releasing research without peer review had run its course with my last post.  But it seems that it will never end.  Here is her latest post and here is the reply that I posted in her comment section:

Eduwonkette is attempting to change the subject. I’ve never disputed that peer review can help provide additional assurances to readers about quality.  The issue is whether research ought to be available to the public even if it has not been peer reviewed.  In attacking the release of my most recent study Eduwonkette seems to be arguing that it is inappropriate to release research without peer review, at least under certain conditions that she only applies to research whose findings she does not like.  If she were going to be consistent, she would have to criticize anyone who releases working papers of their research, which would be almost everyone doing serious research.

 

What’s more, she is still trapped in a contradiction: she can’t say that we should analyze the motives of people who release research directly to the public when assessing whether it is appropriate, while she prevents analysis of her own motives because she blogs anonymously.  As I have now said several times, either she drops the suggestion that we analyze motives or she drops her role as an anonymous blogger.  If she refuses to resolve this contradiction, Ed Week should stop lending her their reputation by hosting her blog.  Let her be inconsistent in blogging at the expense of her own anonymous persona and not drain the respectability of Ed Week.

 

Lastly, the comparison of the market for education policy information and the market for cars comes from my most recent post in our exchange, but she oddly does not credit me here. (See https://jaypgreene.com/2008/07/12/see-were-in-italy/ )  Her position seems to be that we ought to forbid (or at least shun) the sale of used cars without warranties (translation: research without peer review).  My argument is that used cars without warranties come at a risk but there are compensating benefits.  Similarly, non-peer-reviewed research has its risks but also its benefits.

 

UPDATE — My exchange with Eduwonkette continues although it seems increasingly pointless.  Here is my (slightly edited) last comment on her site:

“Let’s make this very concrete. Was it inappropriate for Marcus Winters and I to release our social promotion findings in 2004 without peer review, or should we have waited until it had been peer-reviewed and published (in various forms) in 2006, 2007, and again in 2008? If the appropriate thing is to wait, would interest groups, editorial boards, and bloggers similarly hold their tongues until the additional evidence came in?  Would policymakers hold off on decisions that might have come out differently if they had the suppressed information?

Would it have been OK to release in 2004 as long as we tried to make it obscure enough so that people were less likely to find it? What if interest groups, bloggers, etc… found our obscure finding and promoted them (as has happened with Jesse Rothstein’s paper)?

And in saying ‘working papers and thinktank reports are released for entirely different functions’ you are repeating your call for an analysis of motives. You’ve said that think tanks want to influence policy (bad motive) while academics are trying to advance knowledge with each other (good motive). But if academics are serving the public good, shouldn’t they ultimately want to influence policy? I am an academic who also releases working papers through a think tank. Does that make my motives good or bad? I think all of this analysis of motives is silly when the real issue is the truth of claims, not why people are making those claims. Calling for an analysis of motives is especially silly for someone who is trying to influence people anonymously. The fact that you are trying to influence people through a blog does not give you a free pass from having to be consistent on this.”


See, we’re in Italy…

July 12, 2008

“See, we’re in Italy.  The guy on the top bunk has gotta make the guy on the bottom’s bed all the time.  It’s in the regulations.  If we were in Germany I would have to make yours.  But we’re in Italy, so you’ve
gotta make mine. It’s regulations.”

This is more or less Eduwonkette’s response to my complaint that she can’t argue that the source of information is important in assessing the truth of claims while blogging anonymously.  Her answer is that it’s different for bloggers (in Italy) than for researchers (in Germany).  It’s regulations.

She goes on to describe some differences between different types of information in education policy debates, but it’s not clear why any of those differences would be relevant to whether assessing the source is important for one and not for another.  The closest she comes to explaining why things are meaningfully different is when she says, “And let’s be realistic: an anonymous blogger isn’t shaping public policy.”  So, if information will have no bearing on policy debates, then its source is unimportant.

This would be a consistent argument if she really believed that bloggers had NO influence.  But of course they have at least some influence.  Why else would she and the rest of us be bothering with this?  And if bloggers have some influence, then the same basic principles should apply: either we should analyze the motives of sources of information to assess the truth of claims or we shouldn’t.  I’m in favor of not analyzing motives for anyone since I think that the truth of claims is independent of the motives of the source.  Even bad people can make true arguments.

At the risk of belaboring this issue, maybe I can clarify things by describing the market of ideas in policy debates as being like the market for cars.  We have different levels of confidence in cars that have gone through different processes before being made available for sale.  We could buy a used car from the corner used car dealer with no warranty.  That would be like reading blogs.  We don’t really know whether we are getting a lemon or not, since almost no assurances have been made about quality.  Or we could buy a used car from a larger chain with at least some warranty.  That would be like getting information from newspapers or magazines.  There has been some review and assurance of quality, but we still don’t quite know what we’ll get.  Or we could buy a new car from a major dealer and buy the extended warranty.  That would be like getting information from a peer-reviewed journal.  It may still be a lemon, but we’ve received a lot of assurances that it is not.  And I suppose reading an anonymous blogger is like buying a used car from someone you don’t know in the want ads.  There are trade-offs in getting cars with these different level of assurances about quality, just as there are trade-offs in getting information that has gone through different processes to assure quality. 

Eduwonkette’s argument is essentially that the same rules regarding these trade-offs don’t apply to the market for cars without warranties that do apply to the market for cars with warranties.  My view is that there are only differences in degree, not kind.  Even bad people can sell cars that are good values.

I’ve also noticed that Marc Dean Millot has weighed in on this issue.  He’s just knocking down a straw man.  It is not my position that research doesn’t benefit from peer review.  He can check out my cv to see that I have two dozen peer-reviewed publications, many of which were earlier released directly to the public without review.

I’ve been arguing that the public benefits from seeing research even before it has received peer review because it gets more information faster.  Without the assurances of peer review people will tend to have lower confidence in that research, and their confidence may increase as the research receives those additional assurances.  Millot seems to want to embargo information from the public until it receives peer review.  If he really believes that, then he should criticize every researcher with working papers on the web.  That’s almost everyone doing serious research.

And on his points about ideology tainting research I would suggest that people read Greg Forster’s excellent earlier post on Vouchers: Evidence and Ideology.


Eduwonkette Apologizes

July 8, 2008

I appreciate Eduwonkette’s apology posted on her blog and in a personal email to me.  It is a danger inherent in the rapid-fire nature of blogging that people will write things more strongly and more sweeping than they might upon further reflection.  I’ve already done this on a number of occasions in only a few months of blogging, so I am completely sympathetic and un-offended.

One could argue that these errors demonstrate why people shouldn’t write or read blogs.  In fact some people have argued that ideas need a process of review and editing before they should be shown to the public.  These people tend to be ink-stained employees of “dead-tree” industries or academia, but they have a point: there are costs to making information available to people faster and more easily.

Despite these costs the ranks of bloggers and web-readers have swelled.  There are even greater benefits to making more information available to more people, much faster than the costs of doing so.  People who read blogs and other material on the internet are generally aware of the greater potential for error, so they usually have a lower level of confidence in information obtained from these sources than from other sources with more elaborate review and editing processes.  Some material from blogs eventually finds its way into print and more traditional outlets, and readers increase their confidence level as that information receives further review.

Of course, the same exact dynamics are at work in the research arena.  Releasing research directly to the public and through the mass media and internet improves the speed and breadth of information available, but it also comes with greater potential for errors.  Consumers of this information are generally aware of these trade-offs and assign higher levels of confidence to research as it receives more review, but they appreciate being able to receive more of it sooner with less review.

In short, I see no problem with research initially becoming public with little or no review.  It would be especially odd for a blogger to see a problem with this speed/error trade-off without also objecting to the speed/error trade-offs that bloggers have made in displacing newspapers and magazines.  If bloggers really think ideas need review and editing processes before they are shown to the public, they should retire their laptops and cede the field to traditional print outlets. 

We have a caveat emptor market of ideas that generally works pretty well.

So it was disappointing that following Eduwonkette’s graceful apology, she attempted to draw new lines to justify her earlier negative judgment about our study released directly to the public.  She no longer believes that the problem is in public dissemination of non-peer-reviewed research.  She’s drawn a new line that non-peer-reviewed research is OK for public consumption if it contains all technical information, isn’t promoted by a “PR machine,” isn’t “trying to persuade anybody in particular of anything,” and is released by trustworthy institutions.

The last two criteria are especially bothersome because they involve an analysis of motives rather than an analysis of evidence.  I defended Eduwonkette’s anonymity on the grounds that it doesn’t matter who she is, only whether what she writes is true.  But if Eduwonkette believes that the credibility of the source is an important part of assessing the truth of a claim, then how can she continue to insist on her anonymity and still expect her readers to believe her.  How do we know that she isn’t trying to persuade us of something and isn’t affiliated with an untrustworthy institution if we don’t know who she is?  Eduwonkette can’t have it both ways.  Either she reveals who she is or she remains consistent with the view that the source is not an important factor in assessing the truth of a claim.

No sooner does Eduwonkette establish her new criteria for the appropriate public dissemination of research than we discover that she has not stuck to those criteria herself.  Kevin DeRosa asks her in the comments why she felt comfortable touting a non-peer-reviewed Fordham report on accountability testing. That report was released directly to the public without full technical information, was promoted by a PR machine, comes from an organization that is arguably trying to persuade people of something and whose trustworthiness at least some people question.

So, she articulates a new standard: releasing research directly to the public is OK if it is descriptive and straightforward.  I haven’t combed through her blog’s archives, but I am willing to bet that she cites more than a dozen studies that fail to meet any of these standards.  Her reasoning seems ad hoc to justify criticism of the release of a study whose findings she dislikes.

Diane Ravitch also chimes in with a comment on Eduwonkette’s post: “The study in this case was embargoed until the day it was released, like any news story. What typically happens is that the authors write a press release that contains findings, and journalists write about the press release. Not many journalists have the technical skill to probe behind the press release and to seek access to technical data. When research findings are released like news stories, it is impossible to find experts to react or offer ‘he other side,’ because other experts will not have seen the study and not have had an opportunity to review the data.”

Diane Ravitch is a board member of the Fordham Foundation, which releases numerous studies on an embargoed basis to reporters “like any news story.”  Is it her position that this Fordham practice is mistaken and needs to stop?
