The part of my brain that processes information gets incredibly inflamed when I see/hear things like this. Like, I know that people like him clearly don't process information the same way I do and I accept that. But I cannot unify the concept of an entity which requires logic for everyday interactions with their own reality, alongside one that will outright deny an objective truth that is placed in front of them. It's a failure of reason and an abject denial of who they are as a conscious being and it makes so little sense to me that I feel compelled to go do some unrelated logical thing just to bring balance back to my sphere of reality.
I believe at least a portion of it is intentional and I think you can see that from how he deliberately shuts down and refuses to answer when he's cornered.
