From January’s National Geographic we have an article and a figure showing the disagreement between scientists and laypeople (U.S. adults) on a number of contentious topics related to science. The data come from two polls that surveyed 2,002 U.S. adults and 3,748 members of the American Association for the Advancement of Science (AAAS), asking them, as the article notes, “identical questions about their views on scientific achievement, education, and controversial issues.”
This isn’t much of a surprise, though the 51% gap about the safety of GMOs was larger than I expected. The good news is that half of the American public now accepts the scientifically uncontested fact that our species is warming up the planet. The bad news is that this is only half, and a substantial number of laypeople (and fewer scientists, though still to many) continue to favor more offshore drilling and more fracking. That, of course, just leads to more global warming.
Regarding evolution, the 65% figure that “humans have evolved over time” at first seems to contradict the most recent Gallup poll, shown below, which shows that only 19% of Americans think that humans evolved naturalistically. However, an additional 31% think that humans evolved, but that our evolution was guided by God—a stand that I see as a form of creationism, since it posits that human evolution involved divine intervention. The 31% and 19% add up to 50% who accept human evolution (be it God-guided or naturalistice), but that’s still 15% lower than the poll above. The disparity may reflect a difference in the way the question was asked.
As usual with these articles, the National Geographic piece blames this opinion gap on—scientists, of course (my emphasis in the following):
On most other scientific matters, a widespread “opinion gap” splits the experts from everyday folks, pollsters at the Pew Research Center reported Thursday [Jan.]. The rift persists in long-running issues such as the causes of climate change and the safety of nuclear power. And it crops up in the news today in battles over outbreaks of measles tied to children who haven’t been vaccinated.
Scientists say this opinion gap points to shortcomings in their own skills at reaching out to the public and to deficits in science education. On the last point, at least, the public agrees, with majorities on both sides rating U.S. education as average at best.
[Alan Leshner, AAAS head] argues that scientists can better sway public opinion by making the case for science in smaller venues, such as retirement communities or library groups, instead of the traditional lecture hall. “It is important that the public understands that scientists are people too.”
While I appreciate the need for more and better science education—after all, I’ve spent my career teaching and writing popular science—it’s all too easy to pin the “acceptance gap” on scientists and teachers. Yet the poll described above was taken not of students, but of adults: adults who live in a culture where it’s dead easy to find information about evolution, vaccination, global warming, and GMOs. And if your response is that if one goes online, you find plenty of websites that tout creationism and global-warming denialism, so who’s to judge, well, is the public really so clueless that it doesn’t know to trust in reputable scientists rather than questionable websites?
We’re living in the age of Neil deGrasse Tyson, David Attenborough, Stephen Jay Gould, Genie Scott, Richard Dawkins, and hundreds of other people dedicated to informing the public about science. Can we really argue that we need to go to retirement communities and library groups to effect a sea change? I’ve done such things to promote evolution, and the results have been meager (this is why I prefer to write books, which people can digest and ponder).
It’s time to consider that political, ideological, and religious worldviews actually immunize people against science, and that trying to push science through cracks in those walls won’t work. I’m fully convinced, for instance, that you can’t get Americans to accept evolution by simply teaching evolution. By the time that kids are old enough to learn about it, many of them have already been brainwashed to reject it by religious parents. If we want most Americans to accept evolution, as do most Europeans, we must loosen the grip of religion on society. (That, of course, may require, as Marx noted, eliminating the social conditions that promote religiosity.) After all, as I’ve shown before, there’s a strong negative correlation between the religiosity of a society. Here’s a figure and its caption from a paper I wrote three years ago in Evolution:

The same holds for U.S. states: the top ten states whose residents most readily accept evolution are all among the least religious, while the bottom ten are the most religious. Here’s a figure I made from several sources. States are ranked from highest to lowest in the proportion of people accepting human evolution. Arrows show the ten least religious states (blue) and most religious states (red). (Date for the other 30 states weren’t available.) Note the lack of overlap:
Anti-vaxers and anti-GMOs, too, are often motivated not by ignorance of the facts (which, after all, are readily available), but by what they want to believe. Sociological studies, particularly one done by Dan Kahan, have shown that ideology and “groupthink” are powerful immunizers against facts, and that those conservatives who are more aware of the scientific consensus on issues like evolution and global warming are in fact more resistant to accepting the consensus view! That itself implies that the problem isn’t ignorance of science, but ideological and religious immunization against science.
So, like Rod Serling, I’ll offer, for you consideration, this proposal: scientist are doing a damn good job promoting their findings and raising public awareness. Yes, many scientists don’t do “outreach,” and even those who do are sometimes bad at it. But America is awash in science: it’s not hard to find authorities like the Centers for Disease Control and Prevention telling you about the safety of vaccines, or NASA giving the scientific consensus on global warming. Seek, and ye shall find.
It’s time to stop bashing scientists and teachers as the major cause of Americans’ resistance to the finding of science. That kind of masochism comes from the reluctance of scientists to call out people for their faith and politics. After all, it’s a hell of a lot easier to just beat our breasts and blame ourselves. But the fault, dear Americans, is not in our dearth of scientific stars, like Tyson and Dawkins, but in our faiths and ideologies.
