This probably ought to be a new fallacy–something akin to the Reverend Lovejoy’s wife’s plaintive cry on the Simpson’s:

>”won’t someone please think of the children, think of the children!”

I ran across it yesterday in the pages of the Washington Post. The argument–if you can call it that–seemed to be that Al Gore’s “Inconvenient Truth” makes points which are all basically right and makes recommendations we should follow, but it’s scaring the children, among other things:

>In “An Inconvenient Truth,” Al Gore tells us that unless drastic global changes are made, our cities will be inundated and those of us who haven’t drowned will face a world wracked by cataclysmic weather and swarming with pestilence. One of his devotees, actor Leonardo DiCaprio, is coming out with his own environmental horror movie warning of human extinction if we continue living as we are. This would have a negative effect on the box office, but extinction might be preferable to the future Gore envisions.

>I, however, refuse to see the apocalypse in every balmy day. And I think it’s wrong to let our children believe they’ll be swept away before they get a chance to fret about college admissions. An article in The Post this spring described children anxious, sleepless and tearful about the end; one 9-year-old said she worried about global warming “because I don’t want to die.”

>Usually we want to protect our children from awful events, adjusting the message to suit their age. Certainly we tried to do that after Sept. 11. But an essential part of the global warming awareness movement is the belief that scaring us to death is the best way to spur massive change. Gore explicitly compares warming to the Nazis of the last century and terrorists of this one.

>And a recent New York Times profile of Gore tells that we are to be flooded with “An Inconvenient Truth.” It is going to be shown in schools; book versions for children and young adults and a children’s television show are planned. The global Live Earth concerts scheduled for July 7 are expected to raise millions, going to a three-year public relations effort, headed by Gore, to deluge us with bad news.

>All this is not to say that it’s not getting warmer and that curbing our profligate environmental ways is not a commendable and necessary goal. But perhaps this movement is sowing the seeds of its own destruction — even as it believes the human species has sown its own. There must be a limit to how many calamitous films, books and television shows we, and our children, can absorb.

Commendable and necessary it may be, but won’t someone please think of the children?

Accident, George Will, Hasty Generalization, Ignoratio Elenchi

Empirical generalizations are a matter of common sense, and, yes, generality. Most people know that one counter example is not enough to render it false. Most people. Most people also know, by way of generalization, that general rules are bound to be interpreted in surprising ways some of the time. That’s no surprise. Since the subject of rules is human behavior, there are (1) bound to be exceptions and, (2) instances where people will test the limits of the law, and, more importantly, (3) people who refuse to understand that general rules regarding human behavior are subject to (1) and (2)–most of the time that is.

A rule about workplace speech in California (I bet you can see what’s coming) concerns speech on the employee bulletin boards and email system. Fair enough. There are rules because people abuse public fora. But things went awry (as could have been expected). Here’s what happened, in George Will’s retelling (I recommend one seek an independent source for this):

>Some African American Christian women working for Oakland’s government organized the Good News Employee Association (GNEA), which they announced with a flier describing their group as “a forum for people of Faith to express their views on the contemporary issues of the day. With respect for the Natural Family, Marriage and Family Values.”

>The flier was distributed after other employees’ groups, including those advocating gay rights, had advertised their political views and activities on the city’s e-mail system and bulletin board. When the GNEA asked for equal opportunity to communicate by that system and that board, it was denied. Furthermore, the flier they posted was taken down and destroyed by city officials, who declared it “homophobic” and disruptive.

>The city government said the flier was “determined” to promote harassment based on sexual orientation. The city warned that the flier and communications like it could result in disciplinary action “up to and including termination.”

>Effectively, the city has proscribed any speech that even one person might say questioned the gay rights agenda and therefore created what that person felt was a “hostile” environment. This, even though gay rights advocates used the city’s communication system to advertise “Happy Coming Out Day.” Yet the terms “natural family,” “marriage” and “family values” are considered intolerably inflammatory.

As usual, we make no judgment here on the merits of the case as it stands (it seems poor taste to use language you have chosen on purpose to offend any captive audience–but sometimes that is unavoidable). We would merely like to return to the whole idea of general rules which are bound to confuse some and be abused by others.

Free speech, for instance, means you can assert the false without legal penalty, but you can’t shout fire in a crowded theater. You also can’t use it threaten people with violence of one kind or another. And the limitations continue. It’s a general rule. Rules have exceptions. To think such rules have no exceptions is simply the fallacy of accident (misapplication of a general rule). To suggest, however, that the existence of those exceptions means the rule ought to be abandon is to compound that with the ignoratio elenchi (suggest an extreme conclusion follows from premises the suggest something milder).

Worse than those two things would be to put them together to arrive at a silly conclusion:

>Congress is currently trying to enact yet another “hate crime” law that would authorize enhanced punishments for crimes motivated by, among other things, sexual orientation. A coalition of African American clergy, the High Impact Leadership Coalition, opposes this, fearing it might be used “to muzzle the church.” The clergy argue that in our “litigation-prone society” the legislation would result in lawsuits having “a chilling effect” on speech and religious liberty. As the Oakland case demonstrates, that, too, is predictable.

Not really. It doesn’t demonstrate anything. The Oakland case illustrates that rules (or laws) regarding human behavior will have exceptions and that people will exploit them (sometimes illegitimately). It doesn’t show that there shouldn’t be rules. Besides, if you want to demonstrate any proposition regarding human behavior, you’ll need many many more instances. One won’t inflammatory anecdote won’t do. That’s a hasty generalization.

Ignoratio Elenchi, Kathleen Parker

Blame the victims

Thanks to all the crooks and liars for visiting yesterday.

In other matters, in a rare moment of accountability, the prosecutor of the Duke rape case, Mike Nifong, both lost his job and was disbarred for exaggerating evidence in a rape case. Kathleen Parker, however, is not satisfied–and she has found the real culprit:

>It couldn’t have happened to a more deserving fellow, but the case doesn’t end here. Nifong’s legacy, which ultimately may hurt women more than it does the falsely accused men, will be long-lived. And the politically correct culture that allowed his charade to persist remains securely in place, while those who enabled Nifong walk scot-free.

>Which is to say, before we applaud the tragedy’s finale, we might ask Lady Macbeth if she can recommend a good soap.

>It is tempting to convince oneself that Nifong’s banishment means that all is right in Dukedom. Doubtless, many among Duke’s faculty and administration, as well as random race-baiters, campus feminists, various reporters, commentators and assorted armchair prosecutors would prefer that no one remember their roles in advancing the Nifong farce. (KC Johnson, Brooklyn College history professor, has it all on his Durham-in-Wonderland blog, durhamwonderland.blogspot.com.)

>But they shouldn’t get off so easily. All were participants in the scurrilous witch hunt that unfolded during the last year. All were congregants in the PC Church that sanctifies certain groups as unassailable victims (all minorities and females) and others as condemnable perps (all males, but especially descendants of history’s white oppressors).

>From the beginning, when an African-American stripper — alternately known as a “working mother” and “college student” — claimed that three lacrosse players had raped her, few questioned whether she might be lying or that the men might be telling the truth. A spirit of retributive justice prevailed while feminist law professor Wendy Murphy summarized the zeitgeist on CNN’s “The Situation”: “I never, ever met a false rape claim, by the way. My own statistics speak to the truth.”

Someone is justly punished for perpetrating a fraud (topic of disucssion: can anyone think of some other recent frauds, perhaps broader in scope and with more victims?), by playing on their plainly legitimate racial and class sensitivities, and Parker concludes that their racial sensitivities are to blame. The real upshot of the case is this:

>Thanks to these activists and Nifong — and the dancer who cried wolf — real rape victims may be reluctant to come forward. Others may not get their day in court as intimidated prosecutors anticipate defeat with jurors jaded by the Duke spectacle.

In other words, because of the skepticism Parker advocates about the honesty and motivations of rape victims, their supporters, and legal advocates, real rape victims might not come forward–because Parker might not believe them. And Parker thinks that’s the real crime.

category mistake, Equivocation, Stanley Fish

They’re bound to mess up

In his second commentary on Porphyry's Isagoge, Boethius argues that those who ignore the science of disputation are going to make mistakes (Patrologia Latina 64, 73A). He should have also pointed out that those ignorant of scientific disputations will likewise never learn the "incorrupt truth of reality." I think Stanley Fish falls somewhere in the middle: he's both ignorant of logic and science. He writes:

Dawkins voices distress at an imagined opponent who 'can't see' the evidence or 'refuses to look at it because it contradicts his holy book,' but he has his own holy book of whose truth he has been persuaded, and it is within its light that he proceeds and looks forward in hope (his word) to a future stage of enlightenment he does not now experience but of which he is fully confident. Both in the vocabulary they share 'hope,' 'belief,' 'undoubtedly,' 'there will come a time' and the reasoning they engage in, Harris and Dawkins perfectly exemplify the definition of faith found in Hebrews 11, 'the substance of things hoped for, the evidence of things not seen.'

The evidence for the theory of evolution, my science oriented friends tell me, is vast and testable. On the basis of this vast and testable theory, Dawkins makes judgments (perhaps erroneous ones–remember children, this is science, people are bound to make mistakes, that's the point) about things and events that fall within the purview of the theory, such as the behavior of biological creatures–i.e., living things, like human beings. He claims that as we learn more about the brain–that thing with which we think, and whose wisdom is impaired with chemical substances found in booze–we will probably come to account for more and more human behavior. Confidence or rather faith in such progress is one reason why the study of neurology continues to be funded. One problem with Fish's claim is that he sophistically equivocates on the words "believe," "hope," and so forth. The fact that believers and science types both "believe," "hope" and "have faith" in other words, tells you nothing about what they believe and how they believe, but a lot about the multivalent nature of words. All cognizant beings stand in some kind of relation to the objects of their judgments–but that doesn't mean the objects of these judgments are all the same.

Slashdot linked to this article by the President of the Czech Republic (corrected 6-16). It’s a treat for the connoisseur of bad argument. First a nice straw man argument.

We are living in strange times. One exceptionally warm winter is enough – irrespective of the fact that in the course of the 20th century the global temperature increased only by 0.6 per cent – for the environmentalists and their followers to suggest radical measures to do something about the weather, and to do it right now.

Not sure what to make of this paragraph. The last sentence seems to hang on a sort of ambiguity–in one sense environmentalists want a sort of “central planning.” But not, it seems, to me in the same sense as communism. Whatever it is, it’s a pretty cheap trick, I think.

As someone who lived under communism for most of his life, I feel obliged to say that I see the biggest threat to freedom, democracy, the market economy and prosperity now in ambitious environmentalism, not in communism. This ideology wants to replace the free and spontaneous evolution of mankind by a sort of central (now global) planning.

This paragraph is interesting.

The environmentalists ask for immediate political action because they do not believe in the long-term positive impact of economic growth and ignore both the technological progress that future generations will undoubtedly enjoy, and the proven fact that the higher the wealth of society, the higher is the quality of the environment. They are Malthusian pessimists.

Not sure I see the relevance of the “proven fact,” which, nonetheless, seems plausible to me as a simple generalization, for the problem of global warming. Does this imply that we can simply assume that global warming is not a threat, if it is caused by higher standard of living?

How about this? Perhaps an ignoratio elenchi?

The scientists should help us and take into consideration the political effects of their scientific opinions. They have an obligation to declare their political and value assumptions and how much they have affected their selection and interpretation of scientific evidence.

Should scientists qua scientists really take into consideration the political effects of their scientific opinions (qua scientific opinions)? Even if that’s so, the last sentence is just nutty. But since it has no obvious logical connection to the first sentence (does it follow from the previous one? explain? is it a case of “loosely connected statements?”), we have either, if we take it as an argument, a sort of ignoratio elenchi or red herring, perhaps.

He closes with a series of suggestions that. . .well, my description can’t do them justice. (My favorites are 4 and 5).

  • Small climate changes do not demand far-reaching restrictive measures
  • Any suppression of freedom and democracy should be avoidedc
  • Instead of organising people from above, let us allow everyone to live as he wants
  • Let us resist the politicisation of science and oppose the term “scientific consensus”, which is always achieved only by a loud minority, never by a silent majority
  • Instead of speaking about “the environment”, let us be attentive to it in our personal behaviour
  • Let us be humble but confident in the spontaneous evolution of human society. Let us trust its rationality and not try to slow it down or divert it in any direction
  • Let us not scare ourselves with catastrophic forecasts, or use them to defend and promote irrational interventions
    in human lives.

Let’s get cynical

V.D.Hanson sees right through your pro-immigration stance, university perseffers:

>Most cynical of all, however, are the moralistic pundits, academics and journalists who deplore the “nativism” of Americans they consider to be less-educated yokels. Yet their own jobs of writing, commenting, reporting and teaching are rarely threatened by cheaper illegal workers.

>Few of these well-paid and highly educated people live in communities altered by huge influxes of illegal aliens. In general, such elites don’t use emergency rooms in the inner cities and rural counties overcrowded by illegal aliens. They don’t drive on country roads frequented by those without licenses, registration and insurance. And their children don’t struggle with school curricula altered to the needs of students who speak only Spanish.

Teaching. Cynical.

But perhaps Hanson is on to something, not eve the jobs of the California Republican Party are safe from foreigners.

Bad Explanations

Fun with logic

Whoever thought logic could be so informative:

>The anatomic and physiologic facts of alimentation and reproduction simply do not change based on any cultural setting. In fact, the logical complementarity of the human sexes has been so recognized in our culture that it has entered our vocabulary in the form of naming various pipe fittings either the male fitting or the female fitting depending upon which one interlocks within the other.

>When the complementarity of the sexes is breached, injuries and diseases may occur as noted above. Therefore, based on the simplest known anatomy and physiology, when dealing with the complementarity of the human sexes, one can simply say, Res ipsa loquitur – the thing speaks for itself!

>SECRETARY RICE: Look, let me tell you what I think about Scooter Libby. I think he’s served the country really well. I think he did it to the best of his ability. I think that he is going through an extremely difficult time with his family and for him. And you know, I’m just desperately sorry that it’s happening to him and I — you know, the legal system has spoken, but I tell you, this is a really good guy who is a good public servant and ought to be treated in accordance with that.

I wonder if such feelings of pity are proper for fallen soldiers.

Contradictions, David Brooks, False Dichotomy

Today David Brooks tries to erase any subtlety from the immigration question. The real conflict is between educated globe-trotting elites and local Nascar types. In case you thought that’s the usual silly dichotomy, you’d be right. This time, however, he finds a way to contradict himself and patronize both groups of the dichotomy.

>The conventional view is that an angry band of conservative activists driven by nativism and economic insecurity is killing immigration reform. But this view is wrong in almost every respect.

Three paragraphs of general assertions lead to the following conclusion:

>What’s shaping the immigration debate is something altogether deeper and more interesting. And if you want to understand what it is, start with education. Between 1960 and 1980, the share of Americans enrolled in higher education exploded. The U.S. became the first nation in history with a mass educated class. The members of this class differed from each other in a thousand ways, but they tended to share a cosmopolitan approach to the world. They celebrated cultural diversity and saw ethnocentrism as a sign of backwardness.

No attempt is made to support that claim with any research. Broad, unsupported generalizations–even in the context of a 750 word column–don’t deserve anyone’s serious consideration. If you can’t even point to the right kind of source for that evidence, you probably shouldn’t write it in a newspaper.

Here’s the dichotomy. First, the smart, elite types:

>Liberal members of the educated class celebrated the cultural individualism of the 1960s. Conservative members celebrated the economic individualism of the 1980s. But they all celebrated individualism. They all valued diversity and embraced a sense of national identity that rested on openness and global integration.

Now the yokels:

>This cultural offensive created a silent backlash among people who were not so enamored of rampant individualism, and who were worried that all this diversity would destroy the ancient ties of community and social solidarity. Members of this class came to feel that America’s identity and culture were under threat from people who didn’t understand what made America united and distinct.

But they’re not driven by nativism–they only feel that the ancient ties of solidarity and community of their native culture is under threat from outsiders.

George Will, Post hoc ergo propter, Straw Man

Post tax cuts ergo propter tax cuts

66 Comments

It has become tiresome again to point out the numbskullery of George Will’s arguments. As he often does, today he misrepresents the positions of Bush’s tax cut objectors and asserts that the tax cuts in precisely the way Bush (and Reagan, of course) envision them have made the economy grow.

The first:

>Last Sunday, eight Democratic presidential candidates debated for two hours, saying about the economy . . . next to nothing. You must slog to Page 43 in the 51-page transcript before Barack Obama laments that “the burdens and benefits of this new global economy are not being spread evenly across the board” and promises to “institute some fairness in the system.”

>Well. When in the long human story have economic burdens and benefits been “spread evenly”? Does Obama think they should be, even though talents never are? What relationship of “fairness” does he envision between the value received by individuals and the value added by them? Does he disagree — if so, on what evidence? — with Federal Reserve Chairman Ben Bernanke that “the influence of globalization on inequality has been moderate and almost surely less important than the effects of skill-biased technological change”?

Someone with madder internet skillz than me ought to do a Nexis search for how many times Will writes “Well period” after quoting someone ought of context. I suppose Obama has only those sound bites to offer–no explanation behind them or anything. Just for the record, the complaint about the tax cuts consisted in their uneven distribution. Critics argued that they would have been more effective had people who could spend the money gotten more, and people who don’t spend or don’t need gotten less. That’s the argument–I’m not having it now, so don’t comment on it–so Will ought to deal with that claim. Instead he makes it sound like the Democrats were against any tax cuts or endorsed only the most Robin Hood of tax schemes. Aside from that, he makes it sound like the avoided the topic of the economy at the debate. Well. At the debate, they’re not the ones asking the questions. Besides, the one who did most of the talking was Wolf Blitzer.

The second:

>In the 102 quarters since Ronald Reagan’s tax cuts went into effect more than 25 years ago, there have been 96 quarters of growth. Since the Bush tax cuts and the current expansion began, the economy’s growth has averaged 3 percent per quarter, and more than 8 million jobs have been created. The deficit as a percentage of gross domestic product is below the post-World War II average.

Post tax cuts ergo propter tax cuts.
