It’s the Thought that Counts

Two months ago Dr. Steven Novella, who writes at NeuroLogicaBlog, was invited to be an expert on an acupuncture debate, and directed readers of his blog there to see more and comment. I followed his link and found Opposing Views, a website that hosts debates between experts in the topics debated, and allows readers to comment on individual arguments as well as the broader questions.

There are quite a few debates there that I think readers of this site would be interested in. If debunking pseudoscience is your thing, check out Are Autism and Vaccines Linked? or Does Intelligent Design Have Merit? The more religiously (or irreligiously) opinionated of you might want to take part in Should Religious Symbols be Displayed on Public Property? or even the more fundamental Is There a God? There are of course the classic debates on same-sex marriage and the electoral college, and many others. What’s really nice about the format is that they have verified experts representing their respective sides. While I can’t exactly say I’d vouch for the credibility of some of them (for example, the Discovery Institute), they certainly are experts in whatever it is they’re defending. No one can pout later about how their side was unfairly represented by someone who was unprepared and ill-informed.

So, I’ve been hanging around there for a while, commenting to point out nerdy things like post hoc ergo propter hoc fallacies and trying to engage people in intellectual discussion. I like it, but sometimes I wonder if I’m caught in a bit of a “someone is wrong on the internet” trap. (If these crazy people are on a debate website, I think to myself, surely they want someone to explain to them how they’re being irrational. Four hours later….) Incredibly, the site management does moderate comments. They’re successful at weeding out the YouTube sunshine, but they can’t exactly cull all the stupid ones because that would often introduce a pretty strong bias with respect to a particular debate.

Another reservation I have is that it’s tricky to pick truly debatable topics, and to phrase the questions in ways that facilitate debate with actual clash. Consequently, some of the dialogue gets more frustrating than it really needs to be. Should We Recycle? is actually about whether recycling should be government-mandated or market-driven. Both experts in Should Prayer Be Allowed in Public Schools? ended up agreeing that there’s no problem with students who choose to pray on their own in a non-disruptive way, although many of the commenters (and probably many of the users voting in the poll) didn’t get the memo.

Perhaps more important, however, is an issue about debate philosophy that I’ve struggled with for some time. Is it better to challenge ridiculous opinions out in the open, and let them either flourish or die in the marketplace of ideas, or should we instead refuse to dignify certain viewpoints with a formal recognition such as a debate? Some beliefs are so ludicrous that even agreeing to debate them gives them more credit than they’re due. On the other hand, if any meaningful number of people did hold such beliefs, it would be pretty scary — the kind of thing you might want to take action against. (Would you waste an hour trying to convince an audience not to listen to the Timecube guy? Probably not, unless there actually was an auditorium full of Timecube believers. In that case, I might be tempted to spend a lot more than an hour, if I didn’t run screaming.) A few of the questions on Opposing Views are pretty clear examples of this type of gray area. Are Generic Drugs as Effective as Name Brands? Yes. Yes, they are, because they’re chemically identical. There are also the cases where it’s not so much that one side is definitionally correct, but that anyone who’s devoted some intelligent thought to the matter reaches the same conclusion. Debates like those are harder to pinpoint, but they’re the ones I referred to before, in which eliminating the vapid comments would leave the thread sounding pretty one-sided. Is that debate really worth it, or is it making the struggle to educate and convince people even harder?

I don’t have answers to these questions yet, but I believe they’re worth thinking about and trying to answer. In the meantime, I’ll be around on Opposing Views, and for purely selfish reasons, I hope some of you will be too. There are these structural and philosophical difficulties that may or may not ever be overcome, but I still hate to see someone be both wrong and unchallenged on the internet. (More than 80% of responding users think that acupuncture works, despite the studies that have shown pretend acupuncture to be more effective than the real thing.) If some of you are there with me, we can make a dent in some of those poll results, and fill the comment threads with some higher-level critical analysis. At least for now, I’m naive enough to believe that it makes a difference.

The presidential debate this evening was interesting, but dense. A lot of important points were raised, but I’m unsure about how much the average viewer could take away from it, especially if they haven’t been following the details of the campaign in depth for as long as I have.

Of course, the big question after all debates is who won. I don’t think there was a clear winner (especially if you emphasize clarity in addition to simply having better arguments). Both candidates gave many answers in which they seemed to be listing handfuls of different ideas they wanted to cram in somewhere, rather than directly and succinctly answering the questions posed. Obama definitely came out ahead in terms of appearance and mannerisms, using the format of the debate to directly challenge McCain, while McCain looked down or away from Obama more often and seemed less comfortable. (Also, that tie… stripes were maybe not the best for TV?) It was nice to see the whole event stay civil and focused on issues (even if maybe not on one specific issue at a time).

In the end, I doubt this debate will change many people’s minds. However, both candidates have shown themselves to be skillful at speaking extemporaneously and with expertise on their policies, so I’m definitely looking forward to the next one.

Yesterday I was skipping around on the radio when I came to a Christian station broadcasting a story. Read slowly, deliberately, and with almost comical voices for the different characters, it was the tale of a young girl who had seen a TV preacher explaining why next Saturday was the day of Christ’s Second Coming. He had an equation (?) and a book all about it, and that convinced her, so much so that she began putting up posters all around her town. Her parents, good Christians of course, saw this as crazy behavior, but they weren’t sure how to talk to her about it. After all, if they told her that Jesus wouldn’t be returning on Saturday, she’d start to question whether he’d ever return at all! They didn’t know how to get her to stop acting crazy without shaking her faith.

The real issue seemed so blatant I couldn’t believe they were just sweeping it under the rug. What are the actual reasons for believing in the deity of Jesus, and for believing in the apocalypse accompanied by his return? Why is a televangelist’s take on this not seen as credible, but a local church minister’s is? How can you challenge one irrational belief without applying the same sort of scrutiny to your other beliefs? That’s exactly what the parents were worried about — that the “good” skepticism they wanted to teach her would turn into “bad” skepticism (i.e., distrusting things she was supposed to believe blind).

It got me thinking about… well, not exactly hypocrisy, because I feel like that word should be reserved for intentional cases. I suppose I should say contradictions. We all (perhaps to differing extents) compartmentalize various controversies and rationalize beliefs we’re predisposed to, rather than making judgments from first principles. It’s very easy for this to lead to a situation in which you hold very different opinions simultaneously. The more rational you are, the more likely you are to catch these instances when they do occur, and the quicker you resolve the inconsistency. However, understanding the importance of rational thinking doesn’t mean that you never hold contradictory beliefs.

This is more than just the doctor who smokes, or the obese gym teacher. There’s the “creation scientist” who, after being presented with carefully constructed scientific theories that have withstood rigorous testing, demands proof beyond any shadow of a doubt (clearly misunderstanding the concept of science), but who would never think of turning such a critical lens on the religious beliefs that form their large set of assumptions. There’s the pro-life advocate who wants abortion to be illegal because it is murder, but who would never consider assigning sentences of the same magnitude as what murderers get. There are liberals who think of the Constitution as a set of fundamental principles, which justifies giving absolute protection to expression and religion even if that’s not how the Founding Fathers would have interpreted it — but prefer to look to 18th-century laws to justify gun control in the face of the 2nd Amendment. Alternatively, you have conservatives who would oppose the “fundamental principles” interpretation in general, deferring to the attitudes of the Founders to define Constitutional protections — except in cases about gun control where they’re happy to embrace it.

I’m not saying you can’t believe in making abortion illegal while also supporting low sentences for it. What I’m saying is that, if that’s your position, you have to have reasonably subtle logic to back it up. A good way to examine whether your opinion on a topic is rational is to look at the underlying principles and assumptions, and see if you agree with the implications of those assumptions — in all cases, not just in the limited context of the original situation.

I also think this is good to keep in mind during discussions with others. Say you present some scientific evidence to a creationist, and they respond with criticism of the study methods. It’s not worth your time to defend the study; take their point about scientific rigor and run with it. If they really believe in the scientific method, they can’t make a reasonable claim that creationism is science. Rather than just trying to refute every statement they make as though the conversation were some horrible game of Whack-a-Mole, it can be helpful to agree with them while they’re making the portion of their arguments that are better suited to your side.

This way of thinking — about basic principles that reach beyond isolated opinions — seems especially helpful in political debates. Among most intelligent people, the controversy over, say, school vouchers isn’t really about school vouchers. It’s about underlying ways of thinking about political issues, with opposing views on vouchers being obvious conclusions based on different philosophical starting points. Testing and debating those underlying beliefs is more productive (and much more interesting) than trying to deal with the specific policy issue in question.

Update: I found the radio show I mentioned at the start of this post. It’s called Adventures in Odyssey, and you can read a plot summary of the episode here.
