A few weeks ago
I wrote about what happens [whooping cough etc.] when people respond to well-established science with disbelief or mistrust. As I noted, this is an occupational risk for researchers who work on vaccines (and journalists who write about them), which is why I told a cautionary tale about rejecting science in the face of super-bugs. The piece resonated with readers, but not in the way I’d hoped. Of nearly 220 comments, the vast majority opposed vaccination, for various reasons, rejecting the science.
As I considered how to respond, I wondered how science educators might deal with the chasm between scientific facts and public opinion. Then it struck me: who better to consider rebukes of mainstream science than the Bay Area’s own
Eugenie Scott?
One of America’s most revered science guardians, Scott has long taught rational thought and “science as a way of knowing” as president of the
Bay Area Skeptics and as executive director of the Oakland-based
National Center for Science Education.
Best-known for defending the teaching of evolution in public schools, Scott led NCSE into the climate wars in January, when the center launched its
climate change education initiative to help educators under attack for teaching students about climate change.
I spoke with Scott last week about the challenges of communicating science when evidence runs headlong into ideology, belief, and denial.
Gross: One thing I noticed in some of the comments last week was a tendency to glom onto rare events, like adverse reactions to vaccines, to reject an entire body of science. NCSE hasn’t taken on the anti-vaccination issue, but do you see something similar with those who reject evolution and climate change?
Scott: This kind of anomaly mongering is something that we’ve dealt with for decades with evolution. We’re starting to learn more about it with climate change. One such anomaly is the fact that 1998 was an unusually warm year. So if you measure from 1998 to 2008–the line goes down–cooling has happened, therefore global warming is not taking place.
Now, this is exactly parallel to the kind of anomaly mongering you get with creationism. Where they’ll point to the live mollusk that carbon 14 dating indicated had been dead for 3,000 years, and say, therefore radioisotopic dating is not valid, therefore the Earth is young, therefore, evolution didn’t take place. It’s a logical series of arguments in one sense except the premises are all wrong because these are anomalies.
This satirical cartoon depicting Charles Darwin as an ape, published in 1871, following the publication of Darwin's "The Descent of Man," typified reactions of those who rejected Darwin's contention that humans and apes shared common ancestry.
In the case of the 1998 year, that’s cherry picking the data in a most egregious fashion, because if you pick just about any other year, you’ll find that the climate is getting warmer. And with the living mollusk,
that article was not an attack upon radioisotopic dating, but a methodology article showing the difference between carbon absorption in lacustrine [lake] versus riverine environments and how you must consider the source of your sample.
You find the same thing with people who object to vaccines. They’ll pick some anomalous observation and say, “See, see, we told you vaccines are dangerous,” or “We told you they’re ineffective,” or something along those lines.
To understand this phenomenon you really have to dig deeper into what is motivating people. First of all, I’d like to distinguish between the people who lead these movements versus the people who follow them.
They’re not the ones generating the vaccine anomaly, so to speak, but they’ve read this literature and they’re parroting what they’ve heard. And your heart goes out to them. They’re concerned about their children. They don’t want their kids to get sick. But as many admit, they don’t fully understand the science. And your decisions are obviously going to be influenced by your emotions.
We’re human beings, not automatons. But you need to temper them with good information, empirical information, dare I say scientific information, in order to make the best decisions...
