A Complete Psychological Analysis of Trump's Support Its a long article but worth reading. It paints quite a bleak picture of the modern world and the way that people can be manipulated. I recognise many of these traits in the people I know who support brexit which shows that it is not a specifically American issue. This one chimes with me a lot because I worked with several of these people on a project a few years back. People who have had success in some things believe that they are experts in all fields. You cant reach them because they are bomb proof. 7. The Dunning-Kruger Effect: Humans Often Overestimate Their Political Expertise Some who support Donald Trump are under-informed or misinformed about the issues at hand. When Trump tells them that crime is skyrocketing in the United States, or that the economy is the worst it’s ever been, they simply take his word for it. The Dunning-Kruger effect explains that the problem isn’t just that they are misinformed; it’s that they are completely unaware that they are misinformed, which creates a double burden. Studies have shown that people who lack expertise in some area of knowledge often have a cognitive bias that prevents them from realizing that they lack expertise. As psychologist David Dunning puts it in an op-ed for Politico, “The knowledge and intelligence that are required to be good at a task are often the same qualities needed to recognize that one is not good at that task — and if one lacks such knowledge and intelligence, one remains ignorant that one is not good at the task. This includes political judgment.” These people cannot be reached because they mistakenly believe they are the ones who should be reaching others.
