Post hoc ergo propter

She loves me not

The standard critical thinking examples of fallacies, many argue, just don't ever occur in real life.  No one, for instance, would ever allege that the stock market is tanking on account of someone's appearance on a TV show.  Right?  Wrong.  Take the following interchange between Rep. Raul Grijalva (D-AZ) and CNBC's Michelle Caruso-Cabrera  (Via TPM).

“Representative? You know what, as we’re talking the market is selling off once again,” she told Grijalva. “Every time members of Congress come on, and I’ve got to tell you sir, I think you’re contributing to the fears that we’re going off the fiscal cliff because it doesn’t sound like there’s any compromise in what you’re saying. Do you care that markets are selling off dramatically when it looks like you guys can’t come to a deal?” 

What makes this hilarious is the implication that the stock market, with all of its wonderful complexity, was glued to CNBC, and CNBC's narrative of compromise, such that its hopes sank like a teenage boy at a high school dance when that compromise didn't appear to be imminent.

Sadly, the person who made this comment has a job as a journalist in the financial industry.  One might believe that knowledge, with all of its requirements of believing correctly and evidence and such, might be paramount.

Regrettably, no.

Bad Explanations, Lack of Evidence, Post hoc ergo propter

Post torture, ergo propter torture

Bill O'Reilly is happy Osama Bin Laden is dead.  Apparently, because there are political points to score.  OBL's assassination vindicates the use of torture, and that's cause to do a Bill O'Reilly in-your-face move. Like this:

[T]he big story to emerge from the action is that coerced interrogation gave the CIA vital information used to track bin Laden to his lair. . . .  Of course, that exposition is embarrassing to the left, including President Obama, Vice President Biden and Secretary of State Clinton, who are all on record as saying coerced interrogation does not work. Apparently, they were wrong in a big way.

Ah, so coerced information.  Yes, the result of enhanced interrogation.  Erm, torture.  OK, just so we're clear.  Yes, so, in your face, liberals and lefty-pansies!  And how do we know this?  Well, the story is clear:

The record shows that just three men were waterboarded: Khalid Sheik Mohammed, Abu Zubaydah and Rahim al-Nashiri, all al-Qaida big shots. Under duress, KSM gave up vital information that crippled his terror group and ultimately led U.S. authorities to watch bin Laden's top Pakistani courier. Eventually, that man led the CIA to the compound outside Islamabad.

Well, not so clear.  We captured KSM back in 2003, and he got about 183 sessions with waterboarding.  And then seven years later, we got OBL.  Case closed, right?   Well, no. If waterboarding works the miracles it supposedly does, then why did it take seven more years until we had the actionable intelligence to move on OBL?  If waterboarding works, then shouldn't we have caught him, like, earlier?  And, as I understand it (see the article here in Slate), KSM actually denied knowing the person known as OBL's courier.  That's, like, not what I'd expect as the slam-dunk case for enhancing interrogation.  'Cause aren't the tortured people supposed to say things that are true, instead of false?  That is, if torture works the way torture's supposed to work.  By 2005, remember, folks were saying the OBL trail had "grown cold".

Yeah, so here's another hypothesis.  We eventually stopped the simulated drownings of these folks and returned to the standard forms for interrogation — building trust, going over stories, treating prisoners with dignity.  And once that started working, then we started getting better intelligence.  There was an improvement in surveillance, and with info from Hassan Ghul (who was never waterboarded), OBL got tracked down.  Who knows… maybe the torture delayed the information coming out instead of hastened it.

But still, the far left won't budge. No matter what the facts are about the effectiveness of coerced interrogation, they will deny them. Infuriating.

Yep, it's infuriating, all right.  Infuriating.

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.

Politiculous

On the whole this site concerns itself with top-shelf newspaper punditry primarily because as one descends into syndication things get pretty bad.  So bad, at times, one wonders whether it's even fair to bring our very undergraduate skills of logical analysis to bear.  But sometimes, however, it's just entertaining.  If anything, Bill Maher's Religulous shows us that.  Someone could do the same thing for the poltical world.  Here's one place to start:

An e-mail: "OK, I'll say it…I believe today's massive decline was, in part (and maybe a big "in part"), in fear that the debate tonight won't go well for McCain and the implications that will have for an Obama victory. The likelihood of a recession has been talked about and, probably, factored in to a lot of folks' thinking already… …if tonight's debate tracks well for McCain, you'll see a positive response tomorrow; if it doesn't, hold on; it won't be pretty. Call it: 'Flight to Safety (from Socialism).'"

That's an email an editor at William F.Buckley's National Review thought important enough to repost online–without howls of laughter or at least notes of compassion for the person's diminished intellectual capacity.  So here's the problem, if one were to do a Religulous of politics, where would one begin?

Ad Hominem Abusive, Fallacies of weak induction, General discussion, Post hoc ergo propter, Robert Kagan

Don’t jinx it

Here's what looks like a causal argument–or a causal inference at least–wrapped up in another causal  explanatory inference.  The second one is an ad hominem, the first likely a causal fallacy.  Robert Kagan, of hawkish foreign policy fame writes.

Judged on its own terms, the war on terror has been by far Bush's greatest success. [1] No serious observer imagined after September 11 that seven years would go by without a single additional terrorist attack on U.S. soil. [2] Only naked partisanship and a justifiable fear of tempting fate have prevented the Bush administration from getting or taking credit for what most would have regarded seven years ago as a near miracle. Much of the Bush administration's success, moreover, has been due to extensive international cooperation, especially with the European powers in the areas of intelligence sharing, law enforcement, and homeland security. Whatever else the Bush administration has failed to do, it has not failed to protect Americans from another attack on the homeland. The next administration will be fortunate to be able to say the same — and will be contrasted quite unfavorably with the Bush administration if it cannot."[numbers inserted]

While there thankfully hasn't been another attack (aside from the Anthrax attacks) on U.S. soil, there have been numerous terrorist attacks on U.S. allies (Britain, Spain, Bali, etc.) and U.S. interests (Pakistan, Afghanistan, Iraq, Jordan, and so on).  Aside from the unsettling progress in Afghanistan and Iraq, one might suggest (as many terrorism experts have) that no terrorist attack was planned or attempted on U.S.soil.  So Kagan might be claiming credit for nothing.  In light of such observations, Kagan can hardly claim that "naked partisanship" (and fear of jinxing it) have prevented the Bush administration from taking credit.

So the second claim assumes only the weakest objections to credit-mongering (which, by the way, the Bush administration has not been shy of pointing out), when a person of Kagan's calibre ought to know better.  Given the existence of such views, Kagan ought to be far more circumspect when it comes to definitive causal assertions of the sort that the Bush Administration is responsible for stopping or otherwise preventing attacks on US soil–their mere absence is not evidence for its success.  Besides, given its unique ability to thwart terrorism here, our Allies might wonder why we can't be more helpful to them in this regard.

In fairness to Kagan, there's much more to the argument than cited here.  But then again, a silly argument is a silly argument.

John Hagee, Post hoc ergo propter, Religion

King of the Faeries

Sometimes it gets rather tiresome sorting through the nuanced yet sloppy reasoning of the typical national newspaper pundit, so let's just gaze with wonder at how bad things could be.  Enter Pastor John Hagee, unrepudiated and unrejected friend and supporter of John McCain, maverick:

HAGEE: All hurricanes are acts of God, because God controls the heavens. I believe that New Orleans had a level of sin that was offensive to God, and they are — were recipients of the judgment of God for that. The newspaper carried the story in our local area that was not carried nationally that there was to be a homosexual parade there on the Monday that the Katrina came. And the promise of that parade was that it was going to reach a level of sexuality never demonstrated before in any of the other Gay Pride parades. So I believe that the judgment of God is a very real thing. I know that there are people who demur from that, but I believe that the Bible teaches that when you violate the law of God, that God brings punishment sometimes before the day of judgment. And I believe that the Hurricane Katrina was, in fact, the judgment of God against the city of New Orleans.

Let's say it was.  Now the parade might have been canceled, but lots of non-gay people had their lives and homes destroyed.  I suppose they were just collateral damage. 

UPDATE 4/26/2008

Pastor Hagee has retracted this claim.

Academics, Post hoc ergo propter, Suppressed Evidence

I couldn’t help but think

1 Comment

People may have seen Hillary Clinton’s now much lampooned television advertisement.  She answers the phone at 3 AM, all ready for dealing with some  world crisis.  Some have seen a cause for concern.  Among them Harvard sociology Professor Orlando Patterson.  His op-ed contribution leaves much to be desired in the logic category.  We couldn’t help but think of two points.

First, the phrase "I couldn’t help but think of x" probably ought to be retired.  I don’t know when one can help but think of stuff.  The stuff I think of is mostly involuntary.  Well, here’s the phrase:

I have spent my life studying the pictures and symbols of racism and
slavery, and when I saw the Clinton ad’s central image — innocent
sleeping children and a mother in the middle of the night at risk of
mortal danger — it brought to my mind scenes from the past. I couldn’t
help but think of D. W. Griffith’s “Birth of a Nation,” the racist
movie epic that helped revive the Ku Klux Klan, with its portrayal of
black men lurking in the bushes around white society. The danger
implicit in the phone ad — as I see it — is that the person answering
the phone might be a black man, someone who could not be trusted to
protect us from this threat.

Pointing out that you couldn’t help but think of something seems like an odd way to separate yourself from your thoughts (he does it twice in this piece).  I can’t help but think of a lot of things.  But I can help but write them.

Here’s the second point (this point has, by the way, already been made across the blogosphere.  See the Daily Howler for particularly acute analysis). I think Patterson’s reading of this advert is way of the mark, particularly when it comes to the empirical questions.  He writes, later:

Did the message get through? Well, consider this: people who voted
early went overwhelmingly for Mr. Obama; those who made up their minds
during the three days after the ad was broadcast voted heavily for Mrs.
Clinton.

Don’t know about the implication there.  Seems like there are many obvious countervailing factors that need to be considered before one can buy the inference that the racist ad–actually, not just the ad, the racism of the ad–seriously changed people’s minds.  There’s more:

It is significant that the Clinton campaign used its telephone ad in
Texas, where a Fox poll conducted Feb. 26 to 28 showed that whites
favored Mr. Obama over Mrs. Clinton 47 percent to 44 percent, and not
in Ohio, where she held a comfortable 16-point lead among whites. Exit
polls on March 4 showed the ad’s effect in Texas: a 12-point swing to
56 percent of white votes toward Mrs. Clinton. It is striking, too,
that during the same weekend the ad was broadcast, Mrs. Clinton refused
to state unambiguously that Mr. Obama is a Christian and has never been
a Muslim.

That last claim, I think, is dubious.  The poll reading, without question, leaves much to be desired.  I couldn’t help but think of that. 

False Cause, Ignoratio Elenchi, Michael Gerson, non causa pro causa, oversimplified cause, Post hoc ergo propter

Diagnosis: Evil

3 Comments

To most people, elections are complicated.  Not so to some pundits.  Enter Gerson:

By the summer of 2007, the Republican presidential candidate most closely identified with the war, John McCain, was in serious trouble. Moderates and independents no longer seemed impressed by the fierce, lonely advocate of what many called "escalation." Political observers argued that McCain's money troubles and staff resignations and firings — he went from 120 campaign workers to 50 — were "another nail in Mr. McCain's campaign coffin," showing that "the wheels came off," and leading to "a death spiral that is almost never survived."

If cliches could kill, McCain would have been embalmed and buried.

Yet the Republican candidate most closely identified with the war and the surge performs well in head-to-head polls against the Democrats. The revival of McCain's campaign was possible for one reason: the revival of American fortunes in Iraq. Most categories of violence in Iraq are now down by more than 60 percent, and sectarian attacks in Baghdad have fallen by 90 percent. Sunni tribal leaders are conducting the first large-scale revolt of Arabs against al-Qaeda thuggery — which includes, we learned last week, strapping explosives to a mentally disabled woman and setting off a blast in a market.

McCain seems well suited to deal with this kind of evil — precisely because he would diagnose it as evil.

Every Republican save Ron Paul embraced the most energetic and belligerent of Bush's policies.  How McCain alone is helped by this seems a bit of a mystery.  Besides, someone might even say that the surge hasn't worked (because it has exhausted its own ability to continue without achieving any of its stated goals), but I guess that person would, as Gerson earlier says, would "embrace retreat at any cost."  But Gerson's claim about McCain's surging success is just run of the mill causal fallacy stuff–a little post hoc ergo propter hoc or perhaps some oversimplified cause.  The real travesty is the remark after the dash.  

There is another theologian in this race.  If diagnosing something as evil constitutes a qualification, then why isn't Gerson supporting Mike Huckabee?

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.
