Welcome to the Age of Denial

IN 1982, polls showed that 44 percent of Americans believed God had created human beings in their present form. Thirty years later, the fraction of the population who are creationists is 46 percent.

In 1989, when “climate change” had just entered the public lexicon, 63 percent of Americans understood it was a problem. Almost 25 years later, that proportion is actually a bit lower, at 58 percent.

The timeline of these polls defines my career in science. In 1982 I was an undergraduate physics major. In 1989 I was a graduate student. My dream was that, in a quarter-century, I would be a professor of astrophysics, introducing a new generation of students to the powerful yet delicate craft of scientific research.

Much of that dream has come true. Yet instead of sending my students into a world that celebrates the latest science has to offer, I am delivering them into a society ambivalent, even skeptical, about the fruits of science.

This is not a world the scientists I trained with would recognize. Many of them served on the Manhattan Project. Afterward, they helped create the technologies that drove America’s postwar prosperity. In that era of the mid-20th century, politicians were expected to support science financially but otherwise leave it alone. The disaster of Lysenkoism, in which Communist ideology distorted scientific truth and all but destroyed Russian biological science, was still a fresh memory.

The triumph of Western science led most of my professors to believe that progress was inevitable. While the bargain between science and political culture was at times challenged — the nuclear power debate of the 1970s, for example — the battles were fought using scientific evidence. Manufacturing doubt remained firmly off-limits.

Today, however, it is politically effective, and socially acceptable, to deny scientific fact. Narrowly defined, “creationism” was a minor current in American thinking for much of the 20th century. But in the years since I was a student, a well-funded effort has skillfully rebranded that ideology as “creation science” and pushed it into classrooms across the country. Though transparently unscientific, denying evolution has become a litmus test for some conservative politicians, even at the highest levels.

Meanwhile, climate deniers, taking pages from the creationists’ PR playbook, have manufactured doubt about fundamental issues in climate science that were decided scientifically decades ago. And anti-vaccine campaigners brandish a few long-discredited studies to make unproven claims about links between autism and vaccination.

The list goes on. North Carolina has banned state planners from using climate data in their projections of future sea levels. So many Oregon parents have refused vaccination that the state is revising its school entry policies. And all of this is happening in a culture that is less engaged with science and technology as intellectual pursuits than at any point I can remember.

Thus, even as our day-to-day experiences have become dependent on technological progress, many of our leaders have abandoned the postwar bargain in favor of what the scientist Michael Mann calls the “scientization of politics.”
