The "Safe" Answer

As much as it concerns me that starting this blog with a political topic might turn people off, I'm going to go with my instinct to write what's on my mind. Let's talk about Michelle Bachmann and vaccines.

There have been many articles lately on the remarks the congresswoman made - and later defended - at the Republican debate. In case you haven't been following, I'll summarize: She has spoken out against Gardasil, the HPV vaccine that can help lower a woman's chances of contracting cervical cancer. But she didn't just speak out against the vaccine, she created a rumor that it can cause mental retardation in children.

I'd like to focus on one aspect of this story that I feel has some relevance to science education. Here's the article that got me started thinking about it, for your reference. There's a lot going on in that article, especially about Rick Perry, but I'm not here to talk about politics, so I'm going to skip over all that and focus on one remark made by Ms. Bachmann: “This is the very real concern and people have to draw their own conclusions.”

I find this argument both fascinating and disturbing, and I'm certain I've seen it before, specifically in a video that made the rounds a while ago from the Miss USA pageant. The contestants were asked whether evolution should be taught in schools. The overwhelming majority said no, because they 'don't believe in evolution.' But a precious few gave what was clearly considered to be the "safe" answer: teach the debate. This stance is so common it has become something of a catch phrase within the evolution vs. creationism conversation.

I really think the Miss USA contestants and Ms. Bachmann are saying the same thing: tell people that there is a controversy. Don't represent the facts, don't educate them about science or even mention that conclusive scientific data exists on the subject... No, just tell them "There is a debate going on. You should pay attention, and form your own opinions."

It sounds innocent enough. After all, we want people to think for themselves. So they should look at the debate themselves, right? They should gather the facts and come to a conclusion on their own. But don't be fooled. This argument is already biased toward an anti-science conclusion. It sends people off running in the wrong direction, while veiling itself behind a guise of neutrality.

What Bachmann is really doing here is putting on a show. She starts a rumor that casts her opponent in a negative light and makes her look like a hero for drawing attention to some flaw of her own invention. Then, when she is confronted with real, scientific evidence that her claims are completely fabricated, she throws her hands up and says "That's just what I heard! I'll let people make up their own minds." It sets the stage for anti-science rhetoric, because any retort automatically sounds like an implication that people shouldn't be allowed to make up their own minds, when in reality the public has been handicapped in their ability to approach the subject neutrally. Bachmann creates controversy where there is none, then walks away and lets the scientists talk in circles trying to repair the damage.

The same goes for the "teach the debate" attitude toward evolution. At the end of the day, a science classroom is a science classroom, and it is the responsibility of a teacher only to teach science. Not politics, and certainly not religion. But this idea has somehow become what is considered the "safe" answer. Why do people hear this, and think it's neutral? Or innocent? This is the most politically charged sentiment I've ever heard on the subject of science education. What these people are really saying - both Bachmann and the "teach the debaters" - is that it's okay to make up false rumors about science and medicine, misrepresent or even completely silence the facts, then tell people to come to conclusions based on incomplete and falsified evidence. It's okay to handicap people when their health and education is concerned. Because ignorance endows us with political and social power, and let's be honest, that was really the point all along.

I think if you sat Michelle Bachmann down and asked her if she thinks that science education is important, she would say yes. And she'd mean it, emphatically. But she clearly doesn't fully understand the underlying principle of skepticism or the importance of the scientific process. She is actively crippling the science education of the public when she spreads lies for her own gain.

Given that, know this: when you say "wouldn't it be better to teach the debate?" and I say "No," I'm not trying to keep the truth from you. I'm trying to keep you from allowing the truth to be poisoned for you, before you have a chance to study it for yourself. This isn't a safe answer. It's a highly political answer; a mean trick. And it does tangible harm; don't forget that we're talking about medicine here. The HPV vaccine prevents cancer. It actually prevents cancer. Michelle Bachmann is scaring people into avoiding a vaccine that could save their lives. Why? So she can gain more votes.

So, the next time someone says "You should investigate this debate and draw your own conclusions," start your investigation by asking the question: is there even really a debate going on? I think you'll be surprised how often you'll find the answer is 'No.'

  1. Great post! In re: Bachmann in particular - I don't think it's fair to say she created the rumor that vaccines are linked to mental retardation. The vaccine-autism link goes back to a study with faked data, and has proliferated since (though it's possible she was the first to bring it to this particular vaccine, I don't know).

    More broadly, there's a growing literature in my field - the sociology of science - on just these topics. The leading figure is Naomi Oreskes, a historian of climate science and more recently of manufactured controversies more broadly. She wrote an influential paper back in the early 2000s showing that the debate on anthropogenic climate change had basically ended - not about the details, but about the basic facts that humans were emitting a lot of CO2 that was causing warming. Recently, she and a co-author just published a great book called Merchants of Doubt about how literally the same people that pioneered the "Tobacco Science" controversy transitioned to climate change, bringing with them the same tactics (the ones you describe above). It's horrible to watch it all happening again, and this time not just threatening smokers but the whole planet (for climate change), and everyone's health (especially women) with HPV.

    The thing is, there's a big problem if we go too hard to the other extreme: just trust the scientists, question nothing. Scientific expertise is usually very bounded - science can tell us an awful lot about very specific things, but the story gets very murky when we try to link it up to specific policies, or estimate the costs or benefits to society, and so on. So, we need to engage with science without paying complete obeisance to everything any scientist - or even the majority of specialists in a field - say. But how do you know where to draw that line? How do we create processes for acting on the current best science without messing things up too badly if we turn out to have been wrong? There's other work in my field on that question, e.g. "Acting in an Uncertain World" by Callon et al, on the ideas of reversibility and the precautionary principle (different ways of thinking about acting on uncertain knowledge - which is all knowledge, on some level).

    Finally, have you seen these t-shirts? They are v. amusing, and I am wearing one right now.

  2. Dan you are awesome. Okay, I'm gonna go in order:

    1) Ahhh yes Andrew Wakefield. I specifically didn't bring up the autism story because, frankly, anti-vaccine people make me nerd rage. I didn't want to derail the discussion. But it is such an amazing example. Despite the fact that the case has been put to rest - Andrew Wakefield did start a rumor and falsify data for personal financial gain and was later stripped of his license for it - people still believe his lies. There is an entire movement of people who are anti-vaccine because of his selfish campaign. It saddens and pains me, and I wasn't sure I could incorporate it into this entry without getting overly emotional. So I left it out.

    2) Yes, I do believe Ms. Bachmann is the first one to bring the vaccine debate (ugh) to the HPV vaccine. But it's all the same argument, and as usual, she has no evidence whatsoever.

    3) That sounds awesome. I'll have to add that book to my reading list. Thanks for the heads-up.

    4) Beautifully put. And you're right, one of the most important underlying concepts in science is that we cannot use authority as our basis for truth. I might write an entry on this... In any case, in my life, I treat any argument skeptically for which the person has not cited a source. That is the scientific and literary standard, and I use it as an intellectual standard for myself if the conversation is serious enough. If I hope to make a point in conversation, but I can't immediately cite my source, I try to apologize and request that we revisit the topic later, when perhaps I'm better prepared. Or, alternatively, we continue the conversation with the understanding that my arguments are based on my recollection of an article or source that I don't have in front of me, and should be treated as such: a personal recollection.

    It's tedious and time-consuming, but I think especially in political debates it's worthwhile. These are the people making laws about medicine and science in this country. They shouldn't be allowed to make uninformed decisions that could adversely affect our lives.

    5) Holy crap those shirts are amazing. I'M IN LOVE.
