That it takes a neuroscientist to explain what is wrong with the brains of popular vote loser Donald Trump’s supporters should tell you all you need to know about popular vote loser Donald Trump’s supporters. I guess I just thought they had really tiny brains, but there’s actual scientific evidence that proves something different different going on upstairs in these baskets of deplorables.
So what is going on in those special brains? This was written during the campaign but it’s still incredibly relevant to the few remaining Trump supporters:
1. The Dunning-Kruger Effect:
Some believe that many of those who support Donald Trump do so because of ignorance — basically they 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 seemingly obvious solution would be to try to reach those people through political ads, expert opinions, and logical arguments that educate with facts. Except none of those things seem to be swaying any Trump supporters from his side, despite great efforts to deliver this information to them directly.
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. This 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.” Essentially, they’re not smart enough to realize they’re dumb.
And if one is under the illusion that they have sufficient or even superior knowledge, then they have no reason to defer to anyone else’s judgment. This helps explain why even nonpartisan experts — like military generals and Independent former Mayor of New York/billionaire CEO Michael Bloomberg — as well as some respected Republican politicians, don’t seem to be able to say anything that can change the minds of loyal Trump followers.
Out of immense frustration, some of us may feel the urge to shake a Trump supporter and say, “Hey! Don’t you realize that he’s an idiot?!” No. They don’t. That may be hard to fathom, but that’s the nature of the Dunning-Kruger effect — one’s ignorance is completely invisible to them.
2. Hypersensitivity to Threat
Science has unequivocally shown that the conservative brain has an exaggerated fear response when faced with stimuli that may be perceived as threatening. A classic study in the journal Science found that conservatives have a stronger physiological reaction to startling noises and graphic images compared to liberals. A brain-imaging study published in Current Biology revealed that those who lean right politically tend to have a larger amygdala — a structure that is electrically active during states of fear and anxiety. And a 2014 fMRI study found that it is possible to predict whether someone is a liberal or conservative simply by looking at their brain activity while they view threatening or disgusting images, such as mutilated bodies. Specifically, the brains of self-identified conservatives generated more activity overall in response to the disturbing images.
So how does this help explain the unbridled loyalty of Trump supporters? These brain responses are automatic, and not influenced by logic or reason. As long as Trump continues his fear mongering by constantly portraying Muslims and Mexican immigrants as imminent dangers, many conservative brains will involuntarily light up like light bulbs being controlled by a switch. Fear keeps his followers energized and focused on safety. And when you think you’ve found your protector, you become less concerned with remarks that would normally be seen as highly offensive.
