Hasty Generalization, hollow man, Lack of Evidence, Richard Cohen

The average person must think

Richard Cohen, liberal columnist for the Washington Post, has struggled with some very basic logical notions.  Today is no exception.  Today again he puts on his contrarian hat and accuses a lot of unnamed people–admirers of Sonia Sotomayor (Obama's nominee for the Supreme Court) of elitism and racism.  He writes:

With the nose of a trained columnist, I detect the whiff of elitism-cum-racism emanating from the nomination of Sonia Sotomayor to the Supreme Court. The whiff does not come — Rush Limbaugh and Newt Gingrich notwithstanding — from Sotomayor's own statements; nor does it come from her controversial decision upholding race-based affirmative action. It comes, instead, from the general expression of wow about her background. Imagine, someone from the projects is a success!

"Nobody expects you to be chosen someday for the Supreme Court when your father was a welder with a third-grade education," wrote Richard Lacayo in Time magazine. He is right — the expectations are all otherwise. You can see them on display in many of the reports about Sotomayor's background. She was raised in public housing projects. She grew up in the Bronx, which the average person must think of as a particularly nasty part of Mumbai, and she is, finally and incriminatingly, Puerto Rican. This is all, apparently, very hard to imagine.

With the nose of a trained nonsequitarian, I detect a whiff of it-does-not-follow here.  Cohen's only evidence of a "general expression of wow" is some guy writing in Time and his own "the average person must think."  He then goes on to debunk this not-established-to-exist general expression by running through a list of unnusually successful (and therefore completely unrepresentative) people (for any background) who come from public housing projects (Mike Tyson, Jay-Z, Ken Auletta, etc.).  No one can plausibly deny the empirical possibility of being a success in any endeavor despite having been born in the projects.  But what wows people are the probabilities.  As Cohen ought to know, the expectations for people in the projects are indeed very different, not out of racisim, but out of a realistic sense of how one is successful in America.  I doubt it is really elitism to think that.

Academics, Lack of Evidence, Plain Bad Arguments

This was an episode of the Simpsons

3 Comments

No seriously, this happened (via Steve Benen):

Every winter, David DeWitt takes his biology class to the Smithsonian's National Museum of Natural History, but for a purpose far different from that of other professors.

DeWitt brings his Advanced Creation Studies class (CRST 390, Origins) up from Liberty University in Lynchburg, Va., hoping to strengthen his students' belief in a biblical view of natural history, even in the lion's den of evolution.

His yearly visit to the Smithsonian is part of a wider movement by creationists to confront Darwinism in some of its most redoubtable secular strongholds. As scientists celebrate the 200th anniversary of Charles Darwin's birth, his doubters are taking themselves on Genesis-based tours of natural history museums, aquariums, geologic sites and even dinosaur parks.

"There's nothing balanced here. It's completely, 100 percent evolution-based," said DeWitt, a professor of biology. "We come every year, because I don't hold anything back from the students."

In the Simpsons episode, when the religious types demanded alternatives to Darwinian evolution be taught in school, Principal Skinner proposed Lamarkian evolution.

In other matters, the Post has published an op-ed by an former Harvard endocrinologist on the virtue of science.  He says it's wrong.  The only serious examples he gives are examples of irresponsible science reporting–that's different.  Here's a piece:

When a group of British academic researchers reported last spring that women fond of eating breakfast cereal were more likely to give birth to boys, the story was lapped up by journalists the world over. "Skip breakfast for a daughter, eat up your cereals for a son," advised the Economist, just one of many publications to seize on the report.

The problem with this fascinating study? It appears to be wrong. An analysis led by Stan Young of the National Institute for Statistical Sciences found that the original conclusion was based on poor statistics and is probably the result of chance.

So far, Young's rebuttal, published in January, has received little notice. That it is ignored by many of the media outlets that lavished attention on the original report isn't surprising; in fact, the most remarkable thing is how ordinary that lack of attention may be. A lot of science, it turns out, can't withstand serious scrutiny. Thoughtful analysis by John Ioannidis suggests that more than half of published scientific research findings can't be replicated by other researchers.

Can the results of that one study about the falsity of scientific research be replicated?  The author doesn't bother to find out.  In any case, that is seriously the only evidence for this startling claim offered in the entire piece.  The rest is anecdotal school sucks kind of stuff.  It does, of course, suck.  And science is mostly wrong, that's the point.  I thought.  Or so I learned in school.  But maybe they were wrong about that.

George Will, Inexplicable, Lack of Evidence, Things that are false

Choose your own facts

10 Comments

Everyone has heard the expression, "you can choose your own something or other, but not your own facts."  Well, in a way, no.  Here's the way, according to Washington Post's Ombudsman, Andrew Alexander:

Opinion columnists are free to choose whatever facts bolster their arguments. But they aren't free to distort them.

The question of whether that happened is at the core of an uproar over a recent George F. Will column and The Post's fact-checking process.

That sounds wrong to me.  Two quick reasons.  First, there seems to be a question of scale.  If we have three facts that support a claim, and 97 which don't, an opinion columnist at the post is free to argue talk about the three to the exclusion of the 97.  Let's say, for instance, that one tiny piece of evidence (of dubious origin) holds that a certain person is guilty of a crime, yet a pile of evidence shows the opposite.  The Post's Ombudsman thinks it would be fine to mention the one piece, and not the others, creating the impression that the preponderance evidence leans the other way.

Second, we have a question of context.  Facts have a context in which they are true.  In George Will's recent column (which after all is the occasion for this piece), he alleges–and this is the foundation for his argument–that there was a global cooling hysteria in the 1970s.  This may be true of the popular media, but it wasn't true of scientists (who argued that the climate was warming).  There's a fact, sort of I guess, with no context producing a rather misleading inference.  This is especially true if the audience does not have a very clear grasp of the background information (which information makes Will's columns appear ridiculous). 

Choosing your own facts, in other words, can be a method of distortion, and, in this case it was.

Where’s Foucault when we need him?

5 Comments

George Will's been taking a beating lately–His character, his general ignorance of that of which he comments upon, and, our favorite, his logic have all come under increasing attack recently. Today we can give him a pass on his column. Its silliness is not entirely his fault. For some reason he devotes his column to fawning over the relatively uninteresting analogy between past sexual morality and the supposed moralizing about food by one expert in philosophy at the Hoover institute, Nancy Eberhardt who we are told by Will is "intimidatingly intelligent."

The idea seems to be that in the past we moralized sex, but left food to be a mere matter of taste. Now we moralize food, but leave sex to be a mere matter of taste. I think probably both claims are false, though I'm willing to bite that we have stopped moralizing a lot of sex, and some moralize a lot of their choices involving food.

But, then we run into this sort of confusion:

Most important of all, however, is the difference in moral attitude separating Betty and Jennifer on the matter of food. Jennifer feels that there is a right and wrong about these options that transcends her exercise of choice as a consumer. She does not exactly condemn those who believe otherwise, but she doesn’t understand why they do, either. And she certainly thinks the world would be a better place if more people evaluated their food choices as she does. She even proselytizes on occasion when she can. In short, with regard to food, Jennifer falls within Immanuel Kant’s definition of the Categorical Imperative: She acts according to a set of maxims that she wills at the same time to be universal law.

In heavy-handed contrast:

Even without such personal links to food scarcity, though, it makes no sense to Betty that people would feel as strongly as her granddaughter does about something as simple as deciding just what goes into one’s mouth. That is because Betty feels, as Jennifer obviously does not, that opinions about food are simply de gustibus, a matter of individual taste — and only that.

And again:

Most important of all, Betty feels that sex, unlike food, is not de gustibus. She believes to the contrary that there is a right and wrong about these choices that transcends any individual act. She further believes that the world would be a better place, and individual people better off, if others believed as she does. She even proselytizes such on occasion when given the chance.

And to beat the horse within an inch of its life:

Most important, once again, is the difference in moral attitude between the two women on this subject of sex. Betty feels that there is a right and wrong about sexual choices that transcends any individual act, and Jennifer — exceptions noted — does not. It’s not that Jennifer lacks for opinions about sex, any more than Betty does about food. It’s just that, for the most part, they are limited to what she personally does and doesn’t like.

And to make it clearer still:

As noted, this desire to extend their personal opinions in two different areas to an “ought” that they think should be somehow binding — binding, that is, to the idea that others should do the same — is the definition of the Kantian imperative. Once again, note: Betty’s Kantian imperative concerns sex not food, and Jennifer’s concerns food not sex. In just over 50 years, in other words — not for everyone, of course, but for a great many people, and for an especially large portion of sophisticated people — the moral poles of sex and food have been reversed. Betty thinks food is a matter of taste, whereas sex is governed by universal moral law of some kind; and Jennifer thinks exactly the reverse.  

Fortunately she doesn't draw any substantial conclusions from this. With that sort of genial Brooksy, "foibles of the human race exposing, concealed smirk," she contents herself with running this analogy to its exhaustion while ignoring relevant points of disanalogy, and doing little more than pointing out this curious social change, which perhaps seems to be neither curious, nor a social change, with closer scrutiny. But she closes with this whopper of a post hoc propter hoc fallacy wrapped in a bacony strip of psychoanalyzing explanation and deep-fried in a vat of greasy rhetorical questions:

The rise of a recognizably Kantian, morally universalizable code concerning food — beginning with the international vegetarian movement of the last century and proceeding with increasing moral fervor into our own times via macrobiotics, veganism/vegetarianism, and European codes of terroir — has paralleled exactly the waning of a universally accepted sexual code in the Western world during these same years. 

Who can doubt that the two trends are related? Unable or unwilling (or both) to impose rules on sex at a time when it is easier to pursue it than ever before, yet equally unwilling to dispense altogether with a universal moral code that he would have bind society against the problems created by exactly that pursuit, modern man (and woman) has apparently performed his own act of transubstantiation. He has taken longstanding morality about sex, and substituted it onto food. The all-you-can-eat buffet is now stigmatized; the sexual smorgasbord is not. 

In the end, it is hard to avoid the conclusion that the rules being drawn around food receive some force from the fact that people are uncomfortable with how far the sexual revolution has gone — and not knowing what to do about it, they turn for increasing consolation to mining morality out of what they eat. 

Perhaps it's just me, but I find it surprisingly easy to avoid this conclusion.

Indescribable

Will repeats his performance this weekend with a bizarre attack on the stimulus spending. There are three things that are sticking in Will's craw:

  Brian Tierney is CEO of Philadelphia Media Holdings, which publishes Philadelphia's Inquirer and Daily News and has missed loan payments since June. Pennsylvania Gov. Ed Rendell's spokesman says Tierney has had "a number of conversations" with Rendell about receiving state money that "could come from a number of revenue streams."

He spends about a third of the column attacking this request–why he's doing it is not at all clear. Perhaps we should conclude "Not all spending requests are equally good." But, this doesn't seem to be much of a headline. Maybe I'm missing something here.

 Rep. Henry Waxman, the California Democrat, practiced law for three years, then entered elective office at 29 and has never left, so when he speaks about a world larger than a legislature, and about entities more enmeshed in life's grinding imperatives, he says strange things. Objecting to General Motors, Ford and Chrysler opposing more severe fuel-economy and emissions standards, he says: "They have not yet stopped being controlled by their own self-interest."

This is followed by some equally random sneering at Waxman for supporting the loans to the auto company and emissions standards. I guess in Will's confused mind, the problem with the auto industry is the threat of increased fuel-economy standards. At least, that's the only way I can parse this rambling kvetch.

"Never," Rep. Tom Cole (R-Okla.) said when voting against the stimulus, "have so few spent so much so quickly to do so little." Three of his contentions are correct. The $787 billion price tag is probably at least two-thirds too low: Add the cost of borrowing to finance it, and allow for the certainty that many "temporary" programs will become permanent, and the price soars far above $2 trillion.

But Cole's last contention is wrong. The stimulus, which the Congressional Budget Office says will, over the next 10 years, reduce GDP by crowding out private investment, already is doing a lot by fostering cynicism in the service of opportunism.

And he ends, like he did this weekend, with an easily debunked misrepresentation.  The C.B.O. report is here . It claims that after raising GDP between 1-4% for the next couple of years (and creating 1.3-3.9 million jobs), the effect of the stimulus over the next decade will decrease. Ultimately in 2019 the increased debt will "crowd out" private investment (i.e. capital will have been attracted to government debt rather than private investment) and this will (may?) reduce the GDP by 0.1-0.3%. Yes that is 1/10 of 1 percent reduction. 

I don't see any real problem of logic here, indeed I'm not sure I see any logic whatsoever. Somehow, Will seems to want to suggest that the stimulus bill is some sort of hothouse of "opportunistic" spending. But, these two little vignettes don't go very far to do that. The first might be an illustration of that opportunism, by the second, Will seems to have forgotten what his column was about and the third is just warmed-over blogo-babble that has been discredited. How the editors of the Post ignore the stench of these columns just baffles me.

Lack of Evidence, Michael Gerson

Argumentum ad Obamam

3 Comments

Today Michael Gerson argues that Obama's new politics is all hogwash because, get this because I'm not making this up, some anonymous and unnamed bloggers celebrated the earlier than expected firing of a political appointee.  He writes:

But one major personnel error was made from malice. And it calls into question the depth and duration of President Obama's "new politics."

Interesting remark there at the end.  More on that in a moment.  But here's the evidence for the strikingly general claim that one should now question Obama's "new politics."

Then, the day after the inauguration, Dybul received a call asking him to submit his resignation and to leave by the end of the day. There was no chance to reassure demoralized staffers, or PEPFAR teams abroad, or the confused health ministers of other nations. The only people who seemed pleased were a few blogging extremists, one declaring, "Dybul Out: Thank you, Hillary!!!" 

And following directly:

As in most political hit-and-run attacks, the perpetrator was not anxious to take credit. It seems unlikely to be Hillary Clinton herself — Dybul's ultimate boss at the State Department — who had not even been confirmed when Dybul received his call. But someone at State or the White House determined that sacrificing Dybul would appease a few vocal, liberal interest groups. One high-ranking Obama official admitted that the decision was "political."

It may be the case–but Gerson's evidence for the fairly strong claim that this was an "attack" made from "malice" and is completely non existent.  He doesn't even try to argue that this had anything to do with Obama or any key Obama operative.  

I think we might have stumbled upon a new fallacy–call it argumentum ad Obamam.  Here's how it goes.  Start from the premise that Obama is better than Jesus, then argue that any negative thing remotely linkable to him shows that he is not in fact the real Jesus after all–as omnipotent, omniscient, and omnipresent he would have stopped it!–and that maybe there is no Jesus, and that those who believed in Jesus were gullible fools, because all there exists there is evil.

Well, that's a load of crap, of course.  Not because Obama is Jesus, but because only a nitwit like Gerson would expect him to be (disingenuously–I mean, Jesus, this guy worked for Bush for six solid years, anyone remember Iraq?  Abu Ghraib?) in order to show that silly expectation no one would seriously have to be unfounded.

Lack of Evidence, Peter Beinart

The soft bigotry of low expectations

With Bush leaving office, people are now scrambling to say something nice.  Now enter Peter Beinart, liberal hawk, whose bad foreign policy judgment has propelled him ever upwards, as it nearly always does in the accountability-free profession of punditry (cf. Tom Friedman).  The wronger you are, the more jobs you get.  Anyway, Beinart today counsels "liberals" (by which he means irony-free stoners with no sense of history, practicality, or self-awareness) to admit that the surge–the 2006 increase in troop levels in Iraq–worked, and that it was "courageous" of Bush to do so.  He writes:

It's no longer a close call: President Bush was right about the surge. According to Michael O'Hanlon and Jason Campbell of the Brookings Institution, the number of Iraqi war dead was 500 in November of 2008, compared with 3,475 in November of 2006. That same month, 69 Americans died in Iraq; in November 2008, 12 did.

Violence in Anbar province is down more than 90 percent over the past two years, the New York Times reports. Returning to Iraq after long absences, respected journalists Anthony Shadid and Dexter Filkins say they barely recognize the place.

Is the surge solely responsible for the turnaround? Of course not. Al-Qaeda alienated the Sunni tribes; Moqtada al-Sadr's Mahdi Army decided to stand down; the United States assassinated key insurgent and militia leaders, all of which mattered as much if not more than the increase in U.S. troops. And the decline in violence isn't necessarily permanent. Iraq watchers warn that communal distrust remains high; if someone strikes a match, civil war could again rage out of control.

Moreover, even if the calm endures, that still doesn't justify the Bush administration's initial decision to go to war, which remains one of the great blunders in American foreign policy history. But if Iraq overall represents a massive stain on Bush's record, his decision to increase America's troop presence in late 2006 now looks like his finest hour. Given the mood in Washington and the country as a whole, it would have been far easier to do the opposite. Politically, Bush took the path of most resistance. He endured an avalanche of scorn, and now he has been vindicated. He was not only right; he was courageous.

It's time for Democrats to say so.

He probably could have done better than this if he wanted to praise Bush's courage and wisdom, as he has admitted that perhaps the surge wasn't the cause of Iraq's improvement after all, and, for that matter, he can't really say Iraq has improved.  Well, it has in one sense.  Fewer US troops are dying.  I would say that if you going to make a strong causal claim such as this one, and psychoanalyze people who fail to see the causal connection you do, then you ought to have a more convincing case.

George Will has the courage to say what the people who aren't thinking are thinking:

There will be "some impact," Will declared. "And I think this adds to my calculation — this is very hard to measure — but it seems to me if we had the tools to measure we'd find that Barack Obama gets two votes because he's black for every one he loses because he's black because so much of this country is so eager, a, to feel good about itself by doing this, but more than that to put paid to the whole Al Sharpton/Jesse Jackson game of political rhetoric."

Perhaps if it's hard to measure, and you're a conservative columnist prone to gullibility, you should back off and wait until there's evidence.

David Broder, Inexplicable, Lack of Evidence

Fine

Where I come from–Liberal Academia–debates are won by the party who has (1) the better command of the facts; (2) the better argument.  Where David Broder lives, Washington D.C., such liberal, post-modern notions as facts and argument matter not.  

Palin did just fine on her own, and so did Joe Biden, her sparring partner and the veteran senator from Delaware. In fact, the surprise of the night was that the candidates for the No. 2 job were much livelier and more impressive on the Washington University stage than Barack Obama and McCain had been when they met at Ole Miss.

In a session that was faster-paced and friendlier than the presidential debate, Palin and Biden smiled often at each other while exchanging glances and verbal blows. It was a reminder that politics can be fun — as well as informative.

But it created a mystery of its own. Why in the world has the McCain campaign kept Palin under wraps from her debut at the Republican National Convention until this debate? What were they afraid of?

I asked that question of Steve Schmidt, the McCain campaign manager, and he disputed the premise. Schmidt said that Palin has answered "hundreds" of questions — which will come as news to the reporters who have been traipsing around the country with her. Going into the debate, she had done exactly three television interviews — with ABC, CBS and Fox — and not held a single news conference.

It doesn't appear Broder even watched the debate.  It's one thing to assert that Palin did fine in the debate, followed by (1) a new definition of "fine" and (2) evidence that it applies to her performance in St.Louis.  It's rather another thing simply to state as settled fact that she did fine and then mysteriously wonder why the McCain camp worried about her in the first place.  As anyone who saw those interviews knows, they worried about her because when pressed, it becomes clear she doesn't know anything about anything and, more importantly, she can't even fake it when pressed.

In the wake of David Brooks's critical piece on Sarah Palin, I was going to point out that perhaps I was wrong about the right wing pundit corps.  Maybe they don't marshal any argument, however foolish, in support of their "guy," whoever their guy is, or however silly his policy prescriptions.  That would have been fun to write, as I enjoy being wrong, despite what people may think.  But then I run across this morning's George Will column.  He's not pro-Palin, but that's not going to stop him from making a pitch for McCain.  Well it's not really a pitch for McCain, since he doesn't mention any of McCain's numerous virtues or policy proposals as a reason to vote for him.

What worries George Will, reputedly some kind of libertarian, about a Democratic Presidency is the possibility of (a) an (unlikely I think) expansion of unionization, (b) universal health care, (c) (unlikely again) laws regarding political speech.  As a rule, one ought to dismiss out of hand Will's characterization of these issues, as he is, unfortunately, a serial straw man constructor.  Perhaps one might find better arguments against those things elsewhere.  What's silly is that these three things pose such a danger to the country and liberty, that Will finds their possible vetoing sufficient reason to vote for McCain.  I mean, as they say, come on you've got to be kidding me.  This is all you have?

Well, in other ironic matters, there's this:

Palin is as bracing as an Arctic breeze and delightfully elicits the condescension of liberals whose enthusiasm for everyday middle-class Americans cannot survive an encounter with one. But the country's romance with her will, as romances do, cool somewhat, and even before November some new fad might distract a nation that loves "American Idol" for the metronomic regularity with which it discovers genius in persons hitherto unsuspected of it.  

"Liberals," of course, are elitists–i.e., not "everyday middle-class Americans."  Don't they, by the way, belong to unions?  Unions like the ones whose expansion this piece claims to offer reason to oppose?  Then of course the irony: George Will, cursing elitism, makes fun not only of what lots of people watch, but of their aesthetic judgments as well.  But perhaps he never cursed elitism.

In a related matter–this is dumbfoundingly hilarious.
