In Robert Altermeyer's book on the authoritarian personality I'm pretty sure he said that overly literal thinking is very characteristic of the authoritarian mind.

The book's available online for free so I just Ctrl-F'd "literal" to see if I remembered that right. I don't think I did. He does talk a lot about how right wing authoritarians interpret the Bible literally instead of figuratively and it's fun to think about that in relation to the TRA interpretation of the sacred Tumblr canon.
But I think what I was thinking of was what he'd written about the failures of logic in the authoritarian personality. At risk of derailing (well at least the thread is about authoritarianism!) I decided to C&P this passage because I'd be fascinated to see the same test applied to modern left wing authoritarians.
[Authoritarians] particularly had trouble figuring out that an inference or deduction was wrong. To illustrate, suppose they had gotten the following syllogism:
All fish live in the sea.
Sharks live in the sea..
Therefore, sharks are fish.
The conclusion does not follow, but high RWAs would be more likely to say the reasoning is correct than most people would. If you ask them why it seems right, they would likely tell you, “Because sharks are fish.” In other words, they thought the reasoning was sound because they agreed with the last statement. If the conclusion is right, they figure, then the reasoning must have been right. Or to put it another way, they don’t “get it” that the reasoning matters—especially on a reasoning test.
Deductive logic aside, authoritarians also have trouble deciding whether empirical evidence proves, or does not prove, something. They will often think some thoroughly ambiguous fact verifies something they already believe in.
I recommend the book despite its datedness - as I was skimming through it I kept finding more and more parts that are relevant to the current situation!
