Eleven years later, as I am now definitely writing the last pages in my last book on the subject, I believe circumstances such as “9/11" have nearly … - Bob Altemeyer

The main reason, I submit, is that most of Trump’s backers are authoritarian followers—people who submit too much to the leaders they consider legitimate, trust them too much, and give them too much leeway to do whatever they want. “Well yeah,” you might say. “But that’s like saying an apple is an apple because it’s an apple.” And it would be golden delicious example of a rhetorical tautology except social scientists have had a good, independent way of measuring this kind of authoritarianism since the 1970s. And it was clear from the first studies that political “conservatives”—from ordinary voters to elected officials—tended to score highly on this personality test (Chapter 6 of The Authoritarians, the book on this website). We can gain considerable insight into Donald Trump’s supporters from the research on authoritarianism.

In another sense, however, the fidelity of Trump’s base remains astounding. He has made so many unforced errors because of his lack of understanding and low problem-solving intelligence, his vast ignorance, his enormous, never-ending dishonesty which seems as reflexive as his breathing, his explosive hostility, his uncontrollable vanity, his despicable demeaning of women, his squalid vulgarity, the stupidity of his stereotypes, the shabbiness of his thinking, the buffoonery of his parading, his attacks on the institutions he needs most to safeguard the country, his incredibly poor judgment about the character of those whom he has brought into his administration, his equally mind-numbing lack of judgment about foreign leaders, friend and foe, and his willingness to inflame Americans’ disagreements and turn them into conflagrations which make us that deeply divided house which the Gospels and Abraham Lincoln warned against—how can his supporters have stood so solidly behind him? You’d think they’d be having some second thoughts at least.

Our studies have focused upon the religious decisions made by college freshmen both because they are a convenient group for psychology professors to examine and because they have just emerged from an often turbulent time when they scrutinized the family religion. But will the decisions reached by eighteen-year-olds hold for the rest of their lives? If they have decided to stay in the fold, will they still be found there decades later? If they have decided to chuck the family religion, will they come back to it when they have children of their own? Speaking as middle-aged adults who once thought that "Fifty is really old," but who now consider fifty "much younger than sixty," we can testify that one's views can change as the growth rings accumulate. So maybe youthful decisions to keep or abandon the family religion will be reversed later.
