[A]t the most basic level, conservatives and liberals seem to hold different beliefs about what constitutes “truth.” Finding facts and pursuing evidence and trusting science is part of liberal ideology itself. For many conservatives, faith and intuition and trust in revealed truth appear as equally valid sources of truth.Ehrenreich associates this psychological tendency with submission to authority, in other words conservatives tend to believe what people in authority (within their world) tell them to believe. They believe their preachers, and Donald Trump, for example. In general, they are less inclined to critical thinking and more inclined to tribalism and motivated reasoning. During the election, many purveyors of fake news who were only in it for the clicks and the money tried putting out fakery that might appeal to both Democrats and Republicans; but only the pro-Trump material got results. You will never see the equivalent of the Comet Ping Pong pizzeria pedophilia ring hoax, or birtherism, or "death panels," get over on liberals.
True, some people on both the left and right thought the official story of the 9/11 attack was fake, and some people -- again, left and right -- continue to doubt the official account of the Kennedy assassination. In my view what we are told about these events is more or less the truth, though likely incomplete; but doubt about these events is not nearly as preposterous as birtherism or pizzagate.
We have a problem, however, if some 35-40% of the population is simply never going to believe certain plain facts. What happens when Robert Mueller proves the corruption of the Trump campaign and the candidate, and they simply won't believe it?
