Begging the Question, Hasty Generalization

Clapham Omnibus

8 Comments

Not to put too fine a point on it, but this op-ed in the Wall Street Journal is the worst thing I've read in a while on health care.  Cataloging its sheer dumbness would be a labor of many days, so I'll just pick one representative argument (commenters are free to provide their own, or, as the case may be, defend the brilliance of the author's insight).  But first some context.  The point  is that there is no right to health care.  It supports these with a series of independent arguments.  Here is one of them:

When the supposed right to health care is widely recognized, as in the United Kingdom, it tends to reduce moral imagination. Whenever I deny the existence of a right to health care to a Briton who asserts it, he replies, “So you think it is all right for people to be left to die in the street?”

When I then ask my interlocutor whether he can think of any reason why people should not be left to die in the street, other than that they have a right to health care, he is generally reduced to silence. He cannot think of one.

I can think of a lot of things wrong with this argument.  In the first place, perhaps Dalrymple (that's the author's name) ought to ask different people from the men on the Clapham omnibus.  Secondly, it's weird that the people he asks always give the same answer and are stumped by the same objection.  Third, Dalrymple's question is adequately answered by the person, who takes it as self-evident that no one should be left to die in the street when someone can do something about it. 

Rights, for the average guy on the Clapham omnibus, are like that.  Ask the average American on the 151 Sheridan whether she has the right to private property, and she will say "yes."  Ask her why it shouldn't be the case that no one should take away her goods for no reason at all and she will stare at you and repeat that she has a right to private property.

The recognition of baseline inalienable rights (so we can say for the sake of argument) does not mean one lacks moral imagination.  If that were the case, the existence of moral imagination would nullify the existence of inalienable rights, since, after all, they lack imagination.

Lack of Evidence, Unqualified Authority

The stain of ignorance

In order further to induce skepticism about global warming, George Will now invokes the words of Mark Steyn, a man with no apparent education or expertise on climate science, who in turn rests his global warming denialism on someone who who has no education or expertise on climate science.  Will writes:

The costs of weaning the U.S. economy off much of its reliance on carbon are uncertain, but certainly large. The climatic benefits of doing so are uncertain but, given the behavior of those pesky 5 billion, almost certainly small, perhaps minuscule, even immeasurable. Fortunately, skepticism about the evidence that supposedly supports current alarmism about climate change is growing, as is evidence that, whatever the truth about the problem turns out to be, U.S. actions cannot be significantly ameliorative.

When New York Times columnist Tom Friedman called upon "young Americans" to "get a million people on the Washington Mall calling for a price on carbon," another columnist, Mark Steyn, responded: "If you're 29, there has been no global warming for your entire adult life. If you're graduating high school, there has been no global warming since you entered first grade."

Which could explain why the Mall does not reverberate with youthful clamors about carbon. And why, regarding climate change, the U.S. government, rushing to impose unilateral cap-and-trade burdens on the sagging U.S. economy, looks increasingly like someone who bought a closetful of platform shoes and bell-bottom slacks just as disco was dying.

For the Steyn reference, see here (for the lazy, Steyn's argument rests on the discredited paper of a non-scientist).  As a matter of logic, however, relying on the authority of someone else is a slightly more sound strategy than making stuff up–which is what Will did last time he talked about global warming.

Weak Analogy

The public option

6 Comments

The ongoing (and coming?) health care debate will no doubt be a gold mine of sloppy and dishonest reasoning.  We've already noticed some examples of this already.  Just as the debate over gay marriage seems to inspire certain particular patterns of fallacious reasoning (the equivocation on "marriage" and the slippery slope), I think the health care debate will have its own definitive fallacies.  At the moment, I'm thinking that we'll see a lot of red herring–changing the subject from the less appealing facts of the matter (for instance, the fact that Americans pay more for health care and get less than other developed nations) to tangentially related, yet incendiary, notions such as "socialism."

But I think we'll also see a whole lot of weak analogy–in particular comparisons of health insurance to any other complex consumer product.  Here's one from George Will yesterday:

Some advocates of a public option say health coverage is so complex that consumers will be befuddled by choices. But consumers of many complicated products, from auto insurance to computers, have navigated the competition among providers, who have increased quality while lowering prices.

Those things are different in that they are largely optional purchases.  Sure, you "need" them, but you don't need them.  I might mention, by the way, that auto insurance is legally mandated for all drivers (yet another difference from health insurance–and I doubt, by the way, that Will would advocate such a mandate).  In any case, before one starts comparing health insurance to any other consumer product, one ought to take note of the vast differences.  Few products typical consumers (i.e., anyone of any income level) would absolutely have to buy involve possible outlays of hundreds of thousands of dollars.  And few of those products carry with them (often in their fine print) the real possibility of physical and financial ruin.

In the interest of fairness, I should point out that this entire piece, however bad, does not argue against the feasibility or desirability of single-payer health coverage.  In fact, it does a lot to make the case for it (though not on purpose).  Will's purpose is merely to argue against the "public option."  I think his argument is bad (citing as it does Mort Kondrake and a health insurance industry funded study), but I think such an option is a bad one (for other reasons).  

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.

Judgement at Nuremberg

1 Comment

Kathleen Parker cluelessly asks:

When did we start punishing lawyers for producing opinions with which we disagree? And where does that road lead?

The answer: Nuremberg. 

And that's not the dumbest part of her argument.  This inexplicably moronic assertion (seen by now all over the place, e.g., here) shows up as well:

Moreover, the same technique is used to train our own military personnel, who do not suffer severe physical pain or prolonged mental harm. 

The logic of this claim is completely baffling.  If we use the technique known as waterboarding in order to prepare our military personnel for the kinds of torture that the enemy might use against them, then on that account it's not torture if we use it against the enemy.  But if it's not torture, then we are either tormenting our soldiers for no good reason or we are giving the enemy a pass in virtue of our using it as training.

White whine

1 Comment

White men can't catch a break these days.  First, the white guy lost the Presidential election, now the winner gets to appoint someone to the Supreme Court.  Though Obama has so far said nothing, this hasn't stopped speculation of the weirdest variety:

 

That's a stock image of an average white guy in a tie (from istockphoto.com), not, as one might have imagined, some shunned potential Supreme Court nominee.  Now Richard Cohen–liberal columnist in the Washington Post–expresses his deep concern over the fate of white men under the impossible burden of affirmative action.  He writes:

As the time approaches for President Obama to choose a successor to Justice David Souter, the term "litmus test" will be heard throughout the land. The White House will deny applying any such thing, but the nominee will undoubtedly be chosen according to where she stands on abortion, unions and other issues beloved by liberals. This is fine with me, but what I want to know is where she stands on Frank Ricci. He's a firefighter.  

What follows is a detailed description of Ricci's case (recently argued before the Supreme Court)–how he's been discriminated against on account of his being white, and so forth.  That may be, and by Cohen's very sorry description of the case, it looks absurd.  But as a general rule absurd arguments do not make it all the way to the Supreme Court, so one might wonder.  But that's not the point anyway.  Cohen seems to take this particularly absurd case as representative for how affirmative action needs to end, since, of course, racism is over and so forth (because "For most Americans, race has become supremely irrelevant. Everyone knows this. Every poll shows this.").

It's worse than this, however, because affirmative action (as demonstrated by Cohen's extreme example) is profoundly unfair in principle (like trying to "square a circle."):

Liberalism, a movement in which I hold a conditional membership, would be wise to get wise to what has happened. Blatant affirmative action always entailed a disturbing and ex post facto changing of the rules — oops, you're white. Sorry, not what we wanted. As a consequence, it was not racists who were punished but all whites. There is no need to cling to such a remedy anymore. There is, though, every need to retain and strengthen anti-discrimination laws, especially in areas such as fire departments, where racial discrimination was once endemic. Sufficient progress has been made to revert to treating individuals as individuals. After all, it is not some amorphous entity called "whites" who will suffer: It is un-lieutenant Ricci.

Bill Clinton tried to square the circle of affirmative action in his "Mend It, Don't End It" speech of 1995. It was a moving and eloquent address in which he recounted his region's history, reminding us of the depth and ferocity of racism in the South and elsewhere. Trouble is, the New Haven case proves that affirmative action was not mended at all. It remains noble in its ends and atrocious in its means, and it now provides Obama the chance to use his own family's history — indeed his own history — to show why it ought to conclude.

Affirmative action was never meant to "punish" racists by excluding them from employment.  This underscores Cohen's failure to grasp both the concept of affirmative and the facts of the case he discusses (his only reference is an op-ed in the Wall Street Journal by two conservative think-tankers).  One can found more background on the relevant legal questions here.  Without the necessary and obvious context, Cohen's ranting sounds a bit like this.

Charles Krauthammer, Equivocation, False Dichotomy, Slippery Slope, Straw Man, Things that are false

She blinded me with ethics

There's a certain laughable cluelessness about George Will.  One can seriously wonder whether he really knows that most of his columns advance the shakiest and silliest of arguments.  The same is not true of Charles Krauthammer, his arguments advance a fairly malicious brand of sophistry–in particular, the sophistry of wrongly or dishonestly (i.e., by distortion) claiming others guilty of sophistry.  See for instance his column on Friday (cf., the greatest non sequitur ever foisted)

Today the topic is stem cells.  Two things.  Krauthammer is not incapable of making a reasonable argument, and the stem cell issue deserves to be approached with some amount of seriousness.  Having said that, it seems that Krauthammer in his most recent column does not approach the issue very seriously.  Here's the first bit of unseriousness:

I am not religious. I do not believe that personhood is conferred upon conception. But I also do not believe that a human embryo is the moral equivalent of a hangnail and deserves no more respect than an appendix. Moreover, given the protean power of embryonic manipulation, the temptation it presents to science and the well-recorded human propensity for evil even in the pursuit of good, lines must be drawn. I suggested the bright line prohibiting the deliberate creation of human embryos solely for the instrumental purpose of research — a clear violation of the categorical imperative not to make a human life (even if only a potential human life) a means rather than an end.

On this, Obama has nothing to say. He leaves it entirely to the scientists. This is more than moral abdication. It is acquiescence to the mystique of "science" and its inherent moral benevolence. How anyone as sophisticated as Obama can believe this within living memory of Mengele and Tuskegee and the fake (and coercive) South Korean stem cell research is hard to fathom.

The first part of the second paragraph is false in the sense that Obama does not leave the matter entirely to scientists.  But the second part is a bit of ridiculous hyberbole of the slippery slope variety: if we leave the matter entirely to scientits (who are amoral!), we will get Joseph Mengele (that's a very swift violation of Godwin's law by the way).  Here, for reference, is the relevant section of Obama's speech:

I can also promise that we will never undertake this research lightly. We will support it only when it is both scientifically worthy and responsibly conducted. We will develop strict guidelines, which we will rigorously enforce, because we cannot ever tolerate misuse or abuse. And we will ensure that our government never opens the door to the use of cloning for human reproduction. It is dangerous, profoundly wrong, and has no place in our society, or any society. 

Moving on to the more malicious bits.  Here's Krauthammer again:

That part of the ceremony, watched from the safe distance of my office, made me uneasy. The other part — the ostentatious issuance of a memorandum on "restoring scientific integrity to government decision-making" — would have made me walk out.

Restoring? The implication, of course, is that while Obama is guided solely by science, Bush was driven by dogma, ideology and politics.

It's not a stretch to suggest that the Bush administration had a particular disdain for science and scientists who disagreed with their policy agenda.  See The Republican War on Science, 238ff, for why someone might plausibly assert such a thing about the Bush administration (so spare us the feigned shock please).  But more specifically, the "implication" (that's a logic term) is not that Obama is guided soley (you'll see what he does with this in a moment) by science.  That is an overly strong and decidedly uncharitable version of the claim Obama is making.  Continuing:  

What an outrage. Bush's nationally televised stem cell speech was the most morally serious address on medical ethics ever given by an American president. It was so scrupulous in presenting the best case for both his view and the contrary view that until the last few minutes, the listener had no idea where Bush would come out.

Obama's address was morally unserious in the extreme. It was populated, as his didactic discourses always are, with a forest of straw men. Such as his admonition that we must resist the "false choice between sound science and moral values." Yet, exactly 2 minutes and 12 seconds later he went on to declare that he would never open the door to the "use of cloning for human reproduction."

Does he not think that a cloned human would be of extraordinary scientific interest? And yet he banned it.

Is he so obtuse as not to see that he had just made a choice of ethics over science? Yet, unlike Bush, who painstakingly explained the balance of ethical and scientific goods he was trying to achieve, Obama did not even pretend to make the case why some practices are morally permissible and others not.

This is not just intellectual laziness. It is the moral arrogance of a man who continuously dismisses his critics as ideological while he is guided exclusively by pragmatism (in economics, social policy, foreign policy) and science in medical ethics.

Science has everything to say about what is possible. Science has nothing to say about what is permissible. Obama's pretense that he will "restore science to its rightful place" and make science, not ideology, dispositive in moral debates is yet more rhetorical sleight of hand — this time to abdicate decision-making and color his own ideological preferences as authentically "scientific."

No straw man has been identified, however: Obama has argued that the choice between the two is false, so naturally he does not choose between the two! (See the quote above).  Besides, Obama obviously does not share (see quote above) Krauthammer's nihilistic conception of science, nor does he intend to allow such a science to exist or flourish on the federal dime.  Obama has made it pretty clear that he thinks Bush's restrictions, however surprisingly or drammatically delivered, to be out of sync with where we are scientifically and ethically.  Such an argument, outlined earlier in the speech, does not entail now that anything goes or that there is no moral basis for his view–that would be a falsely dichotomous understanding of ethics and a complete distortion of what Obama said.  The weirdest thing about all of this is that Krauthammer seems to agree with Obama's position.

In any case, it is obvious that the issue of stem cell research is a morally intricate one–one that deserves more serious discussion than Krauthammer would allow.

He Almost Made It

George Will wouldn't let us down and make it through a column without an awful argument. Last three sentences in a column, that on a cursory reading at least was not that unreasonable. Throughout most of the column, he lambasts Obama for liberal opportunism, cynical budget manipulation, and his lack of qualifications for his job, all of which seems mildly cheap. But then he comes through for us:

One afternoon last week, cable news viewers saw, at the top of their screens, the president launching yet another magnificent intention — the disassembly and rearrangement of the 17 percent of the economy that is health care. The bottom of their screens showed the Dow plunging 281 points. Surely the top of the screen partially explained the bottom. 

I can't say whether there is such a causal relationship between Obama's speech and the Dow Industrial drop, but I worry a bit that Will is confusing MSNBC's immediate feedback stuff with the Dow Industrial Averages.

A pro-choice Catholic and a Rabbi walk into a bar

8 Comments

Two columns in the Post.  One from the newly reborn Kathleen Parker, who argues, not that fallaciously, that perhaps lifting the stem cell ban was otiose, as researchers had already found a way around the central moral problem (for some), i.e., the creation of embryonic stem cells from embryos.  Or is it the destruction?  I'm not sure, because she unfortunately characterizes the moral problem in these two distinct ways.  This seems important because some people object to using (therefore destroying) stem cells, others object to creating embryos solely for the purposes of research, which seems, in some sense, much worse.  Nonetheless, other cells, she alleges, work just as well, so lifting the ban on whatever it was that was happening doesn't amount to much.  I have a feeling something in there is false or confused, but this doesn't strike me as a fallacious argument.  So good for Parker, at least we stayed on topic.

Same topic, different writer.  Michael Gerson makes the following very puzzling assertion:

It is probably not a coincidence that Obama has chosen a Roman Catholic — Kansas Gov. Kathleen Sebelius — to implement many of these policies as secretary of the Department of Health and Human Services. Obama has every right to a pro-choice Cabinet. But this appointment seems designed to provide religious cover. It also smacks of religious humiliation — like asking a rabbi to serve the pork roast or an atheist to bless the meal.

Sebelius, though strongly pro-choice, was capable of occasional compromise. But she consistently fought against the serious enforcement of Kansas's late-term abortion restrictions. Kansas became a magnet for late-term abortions.

Still, Sebelius insists that "my Catholic faith teaches me that all life is sacred." This puts her in the same category as House Speaker Nancy Pelosi and Vice President Biden — Catholics who assert the sanctity of life while defending legal abortion. It has also earned Sebelius a firm rebuke from her archbishop.

No, it's not like the Rabbi thing at all: Sebelius is strongly pro-choice, one might presume the rabbi in the joke or the atheist is not "pro pork" or "pro God."  There is much else about this column that would warrant criticism, such as the claim that pro life people's rights are being trampled upon when they lose arguments:

There is a common thread running through President Obama's pro-choice agenda: the coercion of those who disagree with it.

Indeed, laws are coercive.  Elections, someone said, have consequences.  Pointing that out doesn't mean those consequences (i.e., laws which are "coercive"!) are wrong.

Where’s Foucault when we need him?

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.
