Here's the psychological problem that causes Trump supporters to keep getting duped:
"In the past, some prominent psychologists have explained President Donald Trump’s unwavering support by alluding to a well-established psychological phenomenon known as the “Dunning-Kruger effect.” The effect is a type of cognitive bias, where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they don’t have enough knowledge to know they don’t have enough knowledge. Or, stated more harshly, they are “too dumb to know they are dumb.” This simple but loopy concept has been demonstrated dozens of times in well-controlled psychology studies and in a variety of contexts. However, until now, the effect had not been studied in one of the most obvious and important realms—political knowledge."
