Some good quotes:
Science has shown that the conservative brain has an exaggerated fear response when faced with stimuli that may be perceived as threatening.
These brain responses are automatic and not influenced by logic or reason. As long as Trump continues to portray Muslims and Hispanic immigrants as imminent threats, many conservative brains will involuntarily light up like light bulbs being controlled by a switch.
By constantly emphasizing existential threat, Trump may be creating a psychological condition that makes the brain respond positively rather than negatively to bigoted statements and divisive rhetoric.
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.
These Trump supporters are experiencing relative deprivation, and are common among the swing states like Ohio, Michigan, and Pennsylvania. This kind of deprivation is specifically referred to as “relative,” as opposed to “absolute,” because the feeling is often based on a skewed perception of what one is entitled to.
It would be grossly unfair and inaccurate to say that every one of Trump’s supporters have prejudice against ethnic and religious minorities, but it would be equally inaccurate to say that few do.
While the conspiracy theory crowd — who predominantly support Donald Trump and crackpot allies like Alex Jones and the shadowy QAnon — may appear to just be an odd quirk of modern society, some of them may suffer from psychological illnesses that involve paranoia and delusions, such as schizophrenia, or are at least vulnerable to them, like those with schizotypy personalities...
Donald Trump and media allies target these people directly. All one has to do is visit alt-right websites and discussion boards to see the evidence for such manipulation.
