There has been a growing consensus among authorities, especially in the Trump era, that the U.S. is in an epistemological crisis that threatens its democracy. President Barack Obama, for example, in a recent "Atlantic" interview, said: "If we do not have the capacity to distinguish what's true from what's false, then by definition the marketplace of ideas doesn't work. And by definition, our democracy doesn't work. We are entering into an epistemological crisis." If this is true, it is an issue which the academic and journalistic communities--i.e. those in charge of the public's knowledge and education nationwide--need to address. What can be done, for the health of public thought and discourse, to help resolve the national epistemological crisis, and protect democracy? First, there is a need to promote, for all courses and disciplines in all colleges and universities, explicitly and emphatically, that the best--i.e., surely, most reliable--way to think about the world is "on the basis of evidence." Second, and this is critically important, there is no reason "thinking on the basis of evidence" cannot also be taught as the explicit standard and simple lesson throughout secondary schools nationwide. Third, there is a need to promote at every opportunity stronger academic, journalistic and media offerings in American history and civics, to combat the widespread ignorance that has also undermined politics. Fourth and finally, the need to promote to journalists their need to habitually ask, as the first question after hearing any political opinion or unsupported assertion, "What's your evidence?", and if none is forthcoming, to report that fact--that non-event as an event, that the dog didn't bark, as it were--an integral part of their stories.
