Ad hominems and drawing conclusions about character

Ad hominem abusive fallacies are fallacies of relevance.  The basic scheme for the fallacy type is:

P1: S holds that p

P2: S has some vice, X

C1:  Therefore, p is false (or unacceptable).

With my informal logic classes, I have the regular joke: Just because Brenda is a heavy drinker, that doesn't mean that she doesn't know much about politics — She may be a heavy drinker because she knows politics!  That gets lots of laughs, believe me.  But now, consider an argument of a different form, but composed of similar propositions:

P3: p is demonstrably false (i.e., there is sufficient and easily accessible evidence that p is false)

P4: S holds that p, despite P3

C2: Therefore, S has some vice X (where X = vices from simple stupidity to willful ignorance to suffers from ideological thinking)

Importantly, the argument has very similar claims as the ad hominem abusive, but it is of a different form — we are reasoning to S's vice, not from it.  Now, it is clear that this second kind of argument can be made hastily (as there is a big difference between being wrong and being stupid — that's the Fallacy of No Reasonable Alternatives, a species of false dilemma), but it does seem right that P3 and P4 are relevant to C2.  This second form of argument is one either (a) addressed to some third party about S or (b) addressed directly to S in order to request that S reform how she performs in argument regarding p (and perhaps other issues).

With the theoretical apparatus assembled, let's look at Steve Chapman's column, "Why Birtherism is Here to Stay," over at TownHall.com. 

There has never been a shred of persuasive evidence that Obama was born anywhere but Hawaii. But thanks to rampant paranoia and widespread credulity, the myth of his foreign origins gained currency among many people who should know better.

What is Chapman's explanation for this phenomenon — people who believe things that they should know better to not?

A poll taken after the release of his birth certificate showed 18 percent of those who have seen it still aren't convinced.  Something about this president impels many people to accept anything that is said about him, as long as it's unfavorable. . . .   Birthers don't dislike Obama because they think he was born abroad. They think he was born abroad because they dislike him. People of this bent don't proceed from facts to a conclusion. They prefer to reach a conclusion and then scrounge for any facts — or "facts" — that support it.  For them, being told Obama is a natural-born American is like being told he's a loving father and a loyal friend. They won't buy it because it doesn't confirm what they want to be true.

The logician and pragmatist C.S. Peirce called these sorts of patterns of thought 'pseudoreasoning,' and it looks very much like a form of rationalizing.  And the key to the effectiveness of these strategies of thought is that the people making errors with them are not exposed to the consequences of being wrong.  If you pseudoreason your way to believing that you can fly, you pay the consequences.  But if you pseudoreason your way to believing that the President of the United States is a Muslim Marxist AntiChrist, you make lots of friends (and if you stop believing them, you lose those friends).

This is surprising only if you think of political views as a matter of logical reasoning. For many people, they really aren't. They're a way of indulging emotional impulses without suffering painful consequences. . . . [I]f thinking Obama is a foreigner brings you closer to people you like, you come out ahead. Birthers would rather be wrong than be divided from their allies. So the fiction that Obama was born in Kenya will endure, and many Americans will hold fast to a ridiculous article of faith that has been conclusively refuted.

The thing is that this does amount to calling Birthers credulous, ideological, and cognitively blind.  Chapman forgot one thing more for his piece: directing readers to the comments for this piece!

I won’t forget to place roses on your grave

Tu Quoque arguments, it seems to me, have a statute of limitations on when the first of the two inconsistent acts can be relevantly inconsistent with the second. (See my long article in Informal Logic for the full story)  For example, someone may express appropriate surprise at the fact that the altarboy later became an atheist when he was a grownup, but that's not inconsistency in the relevant sense for an accusation of hypocrisy.  The two acts need to be close enough in time for them to be relevant to each other.  And so it's usual when someone runs an argument from inconsistency, she will say something like:

Person S says we should not do X, but then she turns right around and does X.

The important thing is that S turns right around and does it.  If she did X years ago, perhaps S has learned her lesson.  Or she's changed her mind.  Or maybe the facts regarding X have changed.  X may be the best option, nowadays.  The lesson: with charges of hypocrisy, time's relevant.

With that in mind, let's look at Jonah Goldberg's commentary on the (albeit grudging) praise of Ronald Reagan's presidency from liberals.  This is part of a trend he sees. Barry Goldwater, after being demonized by LBJ, was later portrayed as an "avuncular and sage grandfather type." William F. Buckley, too, went from being called a Nazi to later being an actual defender of liberalism.  Reagan, now:

As we celebrate the 100th anniversary of his birth, the Gipper is enjoying yet another status upgrade among liberals. Barack Obama took a Reagan biography with him on his vacation. A slew of liberals and mainstream journalists (but I repeat myself) complimented Obama’s State of the Union address as “Reaganesque.” Time magazine recently featured the cover story “Why Obama (Hearts) Reagan.” Meanwhile, the usual suspects are rewriting the same columns about how Reagan was a pragmatist who couldn’t run for president today because he was too nice, too reasonable, too (shudder) liberal for today’s Republican party.

Trouble is, while Reagan was alive, liberals didn't have too high an opinion of him:

[My] favorite comes from Madame Tussauds Wax Museum in London, which in 1982 held a vote for the most hated people of all time. The winners: Hitler, Margaret Thatcher, Ronald Reagan, and Dracula.

Now, first, note that these are cases where we're looking at things said in 1982 and 2011.  Almost thirty years difference.  Second, note that these inconsistencies are ones distributed over a group, Liberals, not individual people.  Regardless, it's almost as though Goldberg isn't paying attention to the subtext of these retrospectives:  that despite the fact that liberals disagreed with these conservatives, liberals could nevertheless see their virtues as people in retrospect.  And one of the reasons why those virtues are worth mentioning now is that current conservatives so clearly fail to have them.  I take it back.  Goldberg gets that part:

[S]o much of the effort to build up conservatives of the past is little more than a feint to tear down the conservatives of the present.

But, for some reason,  he thinks instead this is a point he's scoring on liberals by showing how they're inconsistent.  Again, in cases where time's changed the variables, sometimes what you've inveighed against earlier becomes the best choice.  Ask any liberal: would you take  Reagan or Buckley over Palin or Goldberg for a decent conversation about government and political norms?  You know the answer.  Goldberg thinks this means that liberals think that the only good conservative is a dead conservative. He's missed the point.  The point, instead, is sadly that all the good conservatives are dead.

There’s no modern Socrates, so you must be…

Victor Davis Hanson is a classicist of some standing.  But he, unfortunately, isn't much for logic. Or, perhaps, simple consistency.  His recent article, "The New Sophists," over at National Review Online, exemplifies these two traits in spades.

Hanson's thesis is that there's just so much double-talk and empty rhetoric, especially from the left, and more especially regarding global warming.  Al Gore "convinced the governments of the Western world that they were facing a global-warming Armageddon, and then hired out his services to address the hysteria that he had helped create."  And the recent record snowfalls in the Northeast are clear evidence that global warming is a sham.  When climate scientists explained that events like this are not only consistent with global warming, but to be expected, Hanson retorts:

The New York Times just published an op-ed assuring the public that the current record cold and snow is proof of global warming. In theory, they could be, but one wonders: What, then, would record winter heat and drought prove?

It's not just climate science that has the double-talk, though.  Hanson sees it with discussions of the Constitution:

One, the Washington Post’s 26-year-old Ezra Klein, recently scoffed on MSNBC that a bothersome U.S. Constitution was “written more than 100 years ago” and has “no binding power on anything.”

To all of this, Hanson makes his analogy with classical Athens and the problem of the sophists:

One constant here is equating wisdom with a certificate of graduation from a prestigious school. If, in the fashion of the sophist Protagoras, someone writes that record cold proves record heat, . . . or that a 223-year-old Constitution is 100 years old and largely irrelevant, then credibility can be claimed only in the title or the credentials — but not the logic — of the writer.

OK. That's a nice point, at least if it were true about the cases he was discussing. (Did Hanson not read the reasons in the NYT article he never cites as to why we'd get crazy snowfalls because of global warming?  If he's going to talk about the article, talk about its argument, too.  Sheesh.  And Klein said it was over 100 years old, and that it's not binding, … but that doesn't matter to Hanson, I guess).  But it's on this point about sophists run amok that Hanson bemoans our fate:

We are living in a new age of sophism — but without a modern Socrates to remind the public just how silly our highly credentialed and privileged new rhetoricians can be.

So we don't have a modern Socrates.  So what's Hanson doing, then?  By that statement, he can't think he's Socrates or doing the job of criticizing the new rhetoricians, can he?  So what is he?  I think I know:  He's another sophist.

Nut Picking

I love meta commentary–that's why it's so much fun to read George Will and Charles Krauthammer–that's what they do: they make (usally wrong) observations on the logic of argument.  Well, at least someone is doing it.  For this reason I was glad to run across a phrase close to our heart here, "nut picking."  It appears in a Dave Weigel column in the Washington Post concerning misconceptions about the "Tea Party Movement." 

The tea party is racist.

2. It's a phenomenon that some activists call "nutpicking" — send a cameraman into a protest and he'll focus on the craziest sign. Yes, there are racists in the tea party, and they make themselves known. But tea party activists, in most cases, root them out. Texas activist Dale Robertson, who held a sign comparing taxpayers to "niggars" at a 2009 rally, was drummed out of that event and pilloried by his peers. Mark Williams, formerly the bomb-throwing spokesman for the Tea Party Express (he once told me he wanted to send the liberal watchdog group Media Matters "a case of champagne" for calling him racist), was booted after penning a parody essay that had the NAACP pining for slavery.

Liberal critics of the tea party make the case that conservative opposition to social spending is often racially motivated. That's not new, though, and it's certainly not the basis for the tea party.

"Nut picking" has its origin in a 2006 Kevin Drum post of the Washington Monthly as far as I can tell.  To be precise, it refers to the all-too-common practice of trolling the comments of internet fora–what you humans call "blogs"–for the crazies.  One then alleges that the crazy commentor represents a typical view of the opposition.  Therefore, etc., as the medievals would say.  Real logicians call this practice "weak manning" or more technically, "the selectional form of the straw man."  

Now to be precise again (sorry, it's my job), the claim that the tea party is racist might be justified (badly, let's say) in some instances by nut picking, but it is not the same as nut picking.  Nut picking may be one of the many mechanisms used to produce an unrepresentative sample, upon which one then makes an inductive generalization.   

Nothing’s Sacrosanct

Ann Coulter’s been paying attention to Elena Kagan’s SCOTUS nomination proceedings.  She even read a profile of Kagan from the New York Times.  Kagan’s aunt notes that the family was intellectually engaged:

“There was thinking, always thinking,” Joyce Kagan Charmatz, Robert Kagan’s sister-in-law, 71, said of the family’s dinner table. “Nothing was sacrosanct.”

That “nothing was sacrosanct” caught Coulter’s eye.  She’s skeptical about whether in a liberal family that there could be a nothing’s-off-limits discussion.  She first observes:

Really? Nothing was sacrosanct? Because in my experience, on a scale of 1-to-infinity, the range of acceptable opinion among New York liberals goes from 1-to-1.001.

And then she ponders:

How would the following remarks fare at a dinner table on the Upper West Side where "nothing was sacrosanct": Hey, maybe that Joe McCarthy was onto something. What would prayer in the schools really hurt? How do we know gays are born that way? Is it possible that union demands have gone too far? Does it make sense to have three recycling bins in these microscopic Manhattan apartments? Say, has anyone read Charles Murray's latest book? Those comments, considered "conversation starters" in most of the country, would get you banned from polite society in New York.

Coulter’s hypothesis is that Kagan’s family was actually a group of insular liberals, people who pretended to be open-minded, willing to hear out all the sides, and so on, but never actually met anyone who had an opposing view.  Coulter knows all those New York liberals, and she knows just how dogmatic they can be: 

Even members of survivalist Christian cults in Idaho at least know people who hold opposing views. New York liberals don't. . . .  Even within the teeny-tiny range of approved liberal opinion in New York, disagreement will get you banned from the premises.

Seriously?  Now, for sure it’d be easy to switch out ‘New York liberals’ with ‘Texas conservatives’ and all the right-wing talking points with lefty talking points, and you’d see just what a bigoted and ridiculous tirade that’d be about conservatives.  Surely, we all know there are dogmatists on both sides. But they don’t define the sides, and they don’t define how parenting happens.  One of the things that Coulter fails to observe is that Joyce Kagan Charmatz is trying to get across that the Kagan family was not one of those dogmatic families you might see on the liberal side.

The larger problem is that Coulter has the worst of the ‘New York liberals’ define them all.  We’ve observed a number of times here at the NonSequitur that this is a form of straw-manning more precisely called weak manning. The basic trope is to find the worst and dumbest representative of a group you hold to be wrong, criticize this representative, and then act as though the group is wrong uberhaupt on the basis of this criticism.  For example, we all have shut-in uncles who surf the web in their bathrobes who are just right of Ron Paul libertarians.  When they say stupid things at family reunions, we don’t think this necessarily impugns libertarianism.  Every time you’re inclined to think that libertarians are stupid, you must remember Robert Nozick was very likely smarter than you. Same goes for Coulter – every time she thinks she can define the class ‘New York liberal,’ their views and their parenting on the basis of the worst of the class, she should exercise some measure of judgment.

Clapham Omnibus

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.

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.

White whine

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.

Compound error

I read these things and shake my head:

Last week’s column about Denis Rancourt, a University of Ottawa professor who is facing dismissal for awarding A-plus grades to his students on the first day of class and for turning the physics course he had been assigned into a course on political activism, drew mostly negative comments.

The criticism most often voiced was that by holding Rancourt up as an example of the excesses indulged in by those who invoke academic freedom, I had committed the fallacy of generalizing from a single outlier case to the behavior of an entire class “Is the Rancourt case one of a thousand such findings this year, or it the most outlandish in 10 years?” (Jack, No. 88).

That's Stanley Fish, the New York Times' interpreter of the academic world.  Sounds like he has been accused of a hasty generalization in the form of "nutpicking."  I'm not particularly interested in the merits of the charge–Fish seems even to concede it.  One minor observation.  I'm sure we are all guilty at one point or another for reasoning that badly.  The difference is that Fish gets to air out his errors in the New York Times.  Anyway, he makes things worse as he defends himself.  He writes (following directly):

It may be outlandish because it is so theatrical, but one could argue, as one reader seemed to, that Rancourt carries out to its logical extreme a form of behavior many display in less dramatic ways. “How about a look at the class of professors who … duck their responsibilities ranging from the simple courtesies (arrival on time, prepared for meetings … ) to the essentials (“lack of rigor in teaching and standards … )” (h.c.. ecco, No. 142). What links Rancourt and these milder versions of academic acting-out is a conviction that academic freedom confers on professors the right to order (or disorder) the workplace in any way they see fit, irrespective of the requirements of the university that employs them.

Eegads!  "Carrying the behavior to its logical extreme" is the characteristic marker of the slippery slope.  And its supported by an alleged fallacy of accident: certain very jerky professors are going to interpret academic freedom very broadly, and, since they will allege this, there must be a logical connection between academic freedom and being a complete nitwit.  Well there isn't.  Just because the connection is alleged by some–how many, not many I would guess–does not mean the connection obtains.  What Fish has done, in other words, is compound the error of one fallacy (the hasty generalization nutpicking variety) with three more:the slippery slope, the fallacy of accident, and the implied hasty generalization again!

Argumentum ad dictum

I can think of the Latin for "bumper sticker" (argumentum ad scriptum bigae in posteriore?).  But Bill Kristol gives us another example in today's Times (see here for another):

But the next morning, as I drove around the Washington suburbs, I saw not one but two cars — rather nice cars, as it happens — festooned with the Obama campaign bumper sticker “got hope?” And I relapsed into moroseness.

Got hope? Are my own neighbors’ lives so bleak that they place their hopes in Barack Obama? Are they impressed by the cleverness of a political slogan that plays off a rather cheesy (sorry!) campaign to get people to drink milk?

And what is it the bumper-sticker affixers are trying to say? Do they really believe their fellow citizens who happen to prefer McCain are hopeless? After all, just because you haven’t swooned like Herr Spörl doesn’t mean you don’t hope for a better world. Don’t McCain backers also have hope — for an America that wins its wars, protects its unborn children and allows its citizens to keep more of their hard-earned income?

But what if all those “got hope?” bumper stickers spur a backlash? It might occur to undecided or swing voters that talk of hope is not a substantive plan. They might be further put off by the haughtiness of Obama’s claim to the mantle of hope. This hope restored my spirits.

Before they fell again. Later that day, I read a report of a fund-raising letter from Obama on behalf of the Democratic Senatorial Campaign Committee, arguing that “We must have a deadlock-proof Democratic majority.”

Someone once claimed that all arguments are "ad hominem."  By this he obviously didn't mean that all arguments commit the fallacy of the same name, but he meant rather that all arguments are directed at some particular person's beliefs.  Regardless, the same principles of charity would apply.

Now this isn't the worst of Kristol's argument, as it is merely a set-up for an even sillier claim [continuing directly]:

Yikes.

But then it occurred to me that one man’s “deadlock-proof” Democratic majority is another’s unchecked Democratic majority. Given the unpopularity of the current Democratic Congress, given Americans’ tendency to prefer divided government, given the voters’ repudiations of the Republicans in 2006 and of the Democrats in 1994 — isn’t the prospect of across-the-board, one-party Democratic governance more likely to move votes to McCain than to Obama?

These are all certainly reasons related in the right kind of way to the conclusion (they won't elect Obama), but Kristol is guilty of two big mistakes.  The first is a priorism–while the evidence he mentions relates to the conclusion (even though the claim about the dissatisfaction with the "democratic" congress is misleading), the availability of empirical data makes such recourse to a priori notions unnecessary.  One can, in other words, track poll data now–poll data which paints a rather different picture (so he at least ought to argue against that).  Second, the repudiation of majorities 12 years a part does not demonstrate much (it's only two instances) about American distrust of one-party rule–besides, in neither of those years were their Presidential elections.

**update: here's someone's suggestion for bumper sticker: adfixum in obice.
