Shawn Otto writes: Four years ago in Scientific American, I warned readers of a growing problem in American democracy. The article, entitled “Antiscience Beliefs Jeopardize U.S. Democracy,” charted how it had not only become acceptable, but often required, for politicians to embrace antiscience positions, and how those positions flew in the face of the core principles that the U.S. was founded on: That if anyone could discover the truth of something for him or herself using the tools of science, then no king, no pope and no wealthy lord was more entitled to govern the people than they were themselves. It was self-evident.
In the years since, the situation has gotten worse. We’ve seen the emergence of a “post-fact” politics, which has normalized the denial of scientific evidence that conflicts with the political, religious or economic agendas of authority. Much of this denial centers, now somewhat predictably, around climate change — but not all. If there is a single factor to consider as a barometer that evokes all others in this election, it is the candidates’ attitudes toward science.
Consider, for example, what has been occurring in Congress. Rep. Lamar Smith, the Texas Republican who chairs the House Committee on Science, Space and Technology, is a climate change denier. Smith has used his post to initiate a series of McCarthy-style witch-hunts, issuing subpoenas and demanding private correspondence and testimony from scientists, civil servants, government science agencies, attorneys general and nonprofit organizations whose work shows that global warming is happening, humans are causing it and that — surprise — energy companies sought to sow doubt about this fact.
Smith, who is a Christian Scientist and seems to revel in his role as the science community’s bête noire, is by no means alone. Climate denial has become a virtual Republican Party plank (and rejecting the Paris climate accord a literal one) with a wide majority of Congressional Republicans espousing it. Sen. Ted Cruz (R–Texas), chairman of the Senate’s Subcommittee on Space, Science and Competitiveness, took time off from his presidential campaign last December to hold hearings during the Paris climate summit showcasing well-known climate deniers repeating scientifically discredited talking points.
The situation around science has grown so partisan that Hillary Clinton turned the phrase “I believe in science” into the largest applause line of her convention speech accepting the Democratic Party nomination. Donald Trump, by contrast, is the first major party presidential nominee who is an outright climate denier, having called climate science a “hoax” numerous times. In his responses to the organization I helped found, ScienceDebate.org, which gets presidential candidates on the record on science, he told us that “there is still much that needs to be investigated in the field of ‘climate change,’” putting the term in scare quotes to cast doubt on its reality. When challenged on his hoax comments, campaign manager Kellyanne Conway affirmed that Trump doesn’t believe climate change is man-made. [Continue reading…]
