Suppressed Evidence

Taking pride in being ignorant

2 Comments

In response to distortions of story, Obama said it seems like certain people "take pride in being ignorant."  Enter Newt Gingrich and Sean Hannity:

GINGRICH: Well, I got a very funny e-mail from a retired military officer in Tampa who pointed out that most tire inflation is done at service stations and you pay for it. And it’s actually a higher profit margin than selling gasoline. So Sen. Obama was urging you to go out and enrich Big Oil by inflating your tires instead of buying gas.

Video here.  The tire inflation advice was not only a strategy to deprive BIG OIL of vast profits, but one to save you money on gas.  So the amount invested on tire pumping (50 cents) will save you much more in fuel efficiency (with all of the accompanying benefits, such as depriving Big Oil of its profits, not filling the atmosphere with that much more carbon, etc.).  In case you're keeping score at home, this would amount to, I think, a fairly textbook case of suppressed evidence.

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.

 But, it raises a more interesting logical point. Commentators and pundits treat positions as though they are arbitrary "commitments"–this  is some sort of political "decisionism" that reduces everything to ideology.This simplifies their job, the only thing they have to track is whether a candidate is 'for' or 'against' something. It also makes for nice narratives of the flip-flop sort. 

What is obfuscated by this lens is that people hold their commitments for reasons. Obama might oppose opening the OCS and ANWR to drilling as a means to the goal of energy independence or lowering gas prices in the short term and long term because there is no reason to believe that they are a means to these ends.

 He can quite consistently support the same policy for some other end–in this case, to gain investment in alternative energy that will probably help move us towards less dependence on foreign energy, help make transportation and other energy uses cheaper, and (pace Krauthammer, maybe "save the planet").

Of course, this subtlety can't be explained in an interview or you suddenly start to look all Al Gore. The viewer either gets this or she/he doesn't. The interviewer deliberately obfuscates a distinction (I suspect) he understands in order to play the "brash interviewer" role he's seen on Fox.

Even after O. makes the point, less pedantically than I have, the interviewer tries the same trick with Yucca mountain. 

I guess that there is a sort of scope fallacy, or a sort amphiboly. "Obama opposes drilling for reason x." becomes "Obama opposes drilling." Or maybe a mistake in generalization: "Obama opposes drilling for reason x" "Obama always opposes drilling." 

 

 

Suppressed Evidence

Surge protector

27 Comments

I heard this on the radio and thought it didn't make any sense.  Even though it's a politician, I'll break with tradition (that's "tradition" by the way, not "rule") and put it up here.  And if you're addicted to "balance," then go find some crazy equivalent howler by Obama so we can talk about that.  It's John McCain criticizing Obama on the surge. 

Oddly enough, my opponent advocates the deployment of two new combat brigades to Afghanistan — in other words, a surge. We're left to wonder how he can deny that the surge in Iraq has succeeded, while at the same time announcing that a surge is just what we need in Afghanistan. I'll leave all these questions for my opponent and his team of 300 foreign policy advisors to work out for themselves. With luck, they'll get their story straight by the time the Obama campaign returns to North America.

The only way this argument would work is if Obama had argued that "surges" (I'm weak on military strategy, but I don't think that's a kind of thing) do not work in principle–which, as far as I know, he didn't. 

I guess I would call this a rather straightforward case of suppressed evidence.  Afghanistan and Iraq are obviously different vis a vis military surging.  Reasons for surging in one place are not reasons for surging in every place.

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.

Robert Samuelson, Straw Man

Back in my day

Maybe we could call this the "grandpa argument": to anyone complaining of a misfortune, you reply by recounting misfortunes much worse.  So if someone says it's hot, tell him about when you forgot to turn on your air conditioning.  When someone says school is hard, tell them about when you went to school and had to run both ways uphill in the snow with bricks.

Robert Samuelson offers us a nice example of this.  He writes:

The specter of depression stalks America. You hear the word repeatedly. Are we in a depression? If not, are we headed for one? The answer to the first question is no; the answer to the second is "almost certainly not." The use of "depression" to describe the economy is a case of rhetorical overkill that speaks volumes about today's widespread pessimism and anxiety. A short history lesson shows why. 

I haven't heard the word "depression" at all (and my quick and informal Google search did not produce anything serious).  I've certainly heard the word "recession," which is a much different thing.  So who is Samuelson talking about?  He doesn't really say.  And this isn't just a lead in.  He's serious.  He concludes:

We are relearning an old lesson: The business cycle isn't dead. Prosperity's pleasures breed complacency and inspire mistakes that, in time, boomerang on financial markets, job creation and production. Just as expansions ultimately tend to self-destruct, so downswings tend to generate self-correcting forces. People pay down debts; pent-up demand develops; surviving companies expand. The Great Depression was an exception. The present economy would have to get much, much, much worse before it warranted the same appraisal.

So there you have it.  Samuelson has conjured up a non-existent opponent, and soundly defeated him.  Now the funny thing is this.  Normally one makes such arguments in order to defeat much stronger ones–or so goes the strategy of the straw man.  Samuelson, however, doesn't seem to suggest that much.  So, while today may be no Great Depression, it doesn't mean that it's not a "recession" (which is another, more interesting question Samuelson might have spent more time addressing).

The proliferation of global warming deniers occupying the highest echelons of the Republican political and intellectual structure (need they be listed here?) notwithstanding, Al Gore is really partisan–and on top of that, some environmentalists seem not to value people more than plants.  So if anyone is responsible for the failure of environmentalism, Michael Gerson argues, it's them.  While we're at it, if anyone is responsible for the failure of women's rights, it's those annoying feminists:

Some Republicans and conservatives are prone to an ideologically motivated skepticism. On AM talk radio, where scientific standards are not particularly high, the attitude seems to be: "If Al Gore is upset about carbon, we must need more of it." Gore's partisan, conspiratorial anger is annoying, yet not particularly relevant to the science of this issue.

This points, however, to a broader problem. Any legislation ambitious enough to cut carbon emissions significantly and encourage new energy technologies will require a broad political and social consensus. Nothing this complex and expensive gets done on a party-line vote. Yet many environmental leaders seem unpracticed at coalition-building. They tend to be conventionally, if not radically, liberal. They sometimes express a deep distrust for capitalism and hostility to the extractive industries. Their political strategy consists mainly of the election of Democrats. Most Republican environmental efforts are quickly pronounced "too little, too late."

Even worse, a disturbing minority of the environmental movement seems to view an excess of human beings, not an excess of carbon emissions, as the world's main problem. In two recent settings, I have heard China's one-child policy praised as an answer to the environmental crisis — a kind of totalitarianism involving coerced birth control or abortion. I have no objection to responsible family planning. But no movement will succeed with this argument: Because we in the West have emitted so much carbon, there needs to be fewer people who don't look like us.

Human beings are not the enemy of sound environmental policy; they are the primary reason sound environmental policy is necessary.

If the movement to confront climate change is perceived as partisan, anti-capitalist and hostile to human life, it is likely to fail, causing suffering for many, including the ice bears. And so the question arises: Will the environment survive the environmentalists?

Now in some respect this might be sound practical advice.  But really, I think Gerson has blamed the unreasonable excesses of the Conservative movement on their perception (which is in reality a caricature) of the environmental movement.  That caricature, of course, exists primarily in their minds.  Sure, you can find some pretty jerky environmentalists, but you need not consider them the key representatives of the movement.

What conclusion would you think would follow from the following (courtesy of Sadly, No!)?

Dark deeds have been conducted in the name of the United States government in recent years: the gruesome, late-night circus at Abu Ghraib, the beating to death of captives in Afghanistan, and the officially sanctioned waterboarding and brutalization of high-value Qaeda prisoners. Now demands are growing for senior administration officials to be held accountable and punished. Congressional liberals, human-rights groups and other activists are urging a criminal investigation into high-level "war crimes," including the Bush administration's approval of interrogation methods considered by many to be torture.

I would think: we are a nation of laws.  The accused will no doubt have better legal representation than their alleged victims (someone said something like that once–who was it?), but they'll still have to answer for their deeds.  That's what I would say.  Here's what the author said:

It's a bad idea. In fact, President George W. Bush ought to pardon any official from cabinet secretary on down who might plausibly face prosecution for interrogation methods approved by administration lawyers. (It would be unseemly for Bush to pardon Vice President Dick Cheney or himself, but the next president wouldn't allow them to be prosecuted anyway—galling as that may be to critics.) The reason for pardons is simple: what this country needs most is a full and true accounting of what took place. The incoming president should convene a truth commission, with subpoena power, to explore every possible misdeed and derive lessons from it. But this should not be a criminal investigation, which would only force officials to hire lawyers and batten down the hatches.

Couldn't this be said about any criminal act?  What the family needs is a full accounting of what happened–outside of the Rashomon-like perspectivism of a criminal trial–so let's grant the accused immunity and  just hear about how he went about his crimes.

Of course that's nonsense not worthy of the most motivated high school debate student.  People will continue to lie to protect their reputations–even when nothing is at stake.  Criminal trials don't really produce truth anyway, they produce, maybe sometimes, justice.

 

Charles Krauthammer, Weak Analogy

Hard power

8 Comments

A people oppressed by years of military rule is a little like a hostage: they're oppressed against their will (no surprise), and they're subject to all sorts of unspeakable brutalities (including murder).  But that's pretty much it.  However difficult it is to rescue hostages (and it's very difficult I'm sure), it's rather easier than rescuing an oppressed people with "democracy" or "humanitarian intervention").  For that reason, Charles Krauthammer's analogizing the Columbian hostage rescue (which used "hard power"–no shooting, however!) to the invasion of Iraq (which used shooting) makes one cringe:

And who's going to intervene? The only country that could is the country that in the past two decades led coalitions that liberated Kuwait, Bosnia, Kosovo and Afghanistan [The only country?  Not only are these situations significantly different from each other, but, Europe participated in all four of them–eds]. Having sacrificed much blood and treasure in its latest endeavor — the liberation of 25 million Iraqis from the most barbarous tyranny of all, and its replacement with what is beginning to emerge as the Arab world's first democracy — and having earned near-universal condemnation for its pains, America has absolutely no appetite for such missions.

And so the innocent languish, as did Betancourt, until some local power, inexplicably under the sway of the Bush notion of hard power, gets it done — often with the support of the American military. "Behind the rescue in a jungle clearing stood years of clandestine American work," explained The Post. "It included the deployment of elite U.S. Special Forces . . . a vast intelligence-gathering operation . . . and training programs for Colombian troops."

Upon her liberation, Betancourt offered profuse thanks to God and the Virgin Mary, to her supporters and the media, to France and Colombia and just about everybody else. As of this writing, none to the United States.

All of this to claim the French are sissies (yet again).  But, as certainly the French know, libertating a hostage from a captor has one clear marker of success: the hostage's life and freedom.  The success metric of an invasion?  Perhaps when they see us, their liberator, as their oppressor.  For then they are truly free.

George Will, Straw Man

Beer

6 Comments

I can think of two primary beer objectors–the late Dr.Atkins (and his crazy low-carb diet) and Christian (therefore European) religious Teetotalers. So why this then?

The gene pools of human settlements became progressively dominated by the survivors — by those genetically disposed to, well, drink beer. "Most of the world's population today," Johnson writes, "is made up of descendants of those early beer drinkers, and we have largely inherited their genetic tolerance for alcohol."

Johnson suggests, not unreasonably, that this explains why certain of the world's population groups, such as Native Americans and Australian Aborigines, have had disproportionately high levels of alcoholism: These groups never endured the cruel culling of the genetically unfortunate that town dwellers endured. If so, the high alcoholism rates among Native Americans are not, or at least not entirely, ascribable to the humiliations and deprivations of the reservation system. Rather, the explanation is that not enough of their ancestors lived in towns.

But that is a potential stew of racial or ethnic sensitivities that we need not stir in this correction of Investor's Business Daily. Suffice it to say that the good news is really good: Beer is a health food. And you do not need to buy it from those wan, unhealthy-looking people who, peering disapprovingly at you through rimless Trotsky-style spectacles, seem to run all the health food stores.

Doesn't Whole Foods, a kind of health food store, sell beer?  Nice bit of paralipsis also about racial "sensitivities."
