People in general are biased to ignore sources that don't agree with their existing opinions. Trump may be an extreme example. This is probably what still allows Trump supporters to exist -- I have no other way to explain how 30% of population can ignore the things that happened recently and keep declaring support for Trump. Certainly it is not intelligence because roughly 50% of voters elected Trump and there had to be a lot of people with above-average intelligence who voted for him regardless of completely incoherent campaign.
