This short video from a South Park episode exemplifies...
... the current Republican/Democratic divide to me:
Several Trump supporters took his hydroxychloroquine recommendations seriously too. After all, it's mostly business men put in charge of doctors and scientists in this country anyway... so they must be more trustworthy about such matters, right?
(Actually, I doubt Trump supporters even attempted that kind of reasoning about it.)
No wonder only 6% of scientists in this country identify themselves as Republicans:

Too many right-wing authoritarians in this country who shut off their critical thinking capacities, or it might lead them to uncomfortable contradictions to their long-held group identities:

According to Altemeyer, the above-mentioned reasoning flaws prevalent among authoritarians are all connected to their instinct to not think for themselves but to absorb their beliefs from their group, with particular deference to what the leader tells them to believe. If they are to absorb whatever they're taught, they must not think critically about the logic of what they're taught. A person who can think critically can achieve sustainable beliefs as they come closer to the truth, but an unthinking authoritarian can only achieve sustainable beliefs if they stubbornly stick to what they were taught no matter what outsiders tell them.
