America's Cult of Ignorance—And the Death of Expertise
“There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'”
—Isaac Asimov
In the early ’90s, a small group of “AIDS denialists,” including a University of California professor named Peter Duesberg, argued against virtually the entire medical establishment’s consensus that the human immunodeficiency virus (HIV) was the cause of Acquired Immune Deficiency Syndrome. Science thrives on such counterintuitive challenges, but there was no evidence for Duesberg’s beliefs, which turned out to be baseless. Once researchers found HIV, doctors and public health officials were able to save countless lives through measures aimed at preventing its transmission.
The Duesberg business might have ended as just another quirky theory defeated by research. The history of science is littered with such dead ends. In this case, however, a discredited idea nonetheless managed to capture the attention of a national leader, with deadly results. Thabo Mbeki, then the president of South Africa, seized on the idea that AIDS was caused not by a virus but by other factors, such as malnourishment and poor health, and so he rejected offers of drugs and other forms of assistance to combat HIV infection in South Africa. By the mid-2000s, his government relented, but not before Mbeki’s fixation on AIDS denialism ended up costing, by the estimates of doctors at the Harvard School of Public Health, well over three hundred thousand lives and the births of some thirty-five thousand HIV-positive children whose infections could have been avoided. Mbeki, to this day, thinks he was on to something.
Many Americans might scoff at this kind of ignorance, but they shouldn’t be too confident in their own abilities. In 2014, the Washington Post polled Americans about whether the United States should engage in military intervention in the wake of the 2014 Russian invasion of Ukraine. The United States and Russia are former Cold War adversaries, each armed with hundreds of long-range nuclear weapons. A military conflict in the center of Europe, right on the Russian border, carries a risk of igniting World War III, with potentially catastrophic consequences. And yet only one in six Americans—and fewer than one in four college graduates—could identify Ukraine on a map. Ukraine is the largest country entirely in Europe, but the median respondent was still off by about 1,800 miles.
Map tests are easy to fail. Far more unsettling is that this lack of knowledge did not stop respondents from expressing fairly pointed views about the matter. Actually, this is an understatement: the public not only expressed strong views, but respondents actually showed enthusiasm for military intervention in Ukraine in direct proportion to their lack of knowledge about Ukraine. Put another way, people who thought Ukraine was located in Latin America or Australia were the most enthusiastic about the use of U.S. military force.
These are dangerous times. Never have so many people had so much access to so much knowledge and yet have been so resistant to learning anything. In the United States and other developed nations, otherwise intelligent people denigrate intellectual achievement and reject the advice of experts. Not only do increasing numbers of lay people lack basic knowledge, they reject fundamental rules of evidence and refuse to learn how to make a logical argument. In doing so, they risk throwing away centuries of accumulated knowledge and undermining the practices and habits that allow us to develop new knowledge. ...
