Psychological research (Carney et al 2008) suggests that liberals score higher on "Openness to Experience" (a Big Five personality trait). This trait correlates with a preference for novelty, ambiguity, and critical inquiry.

I think the stochastic parrot criticism is a bit unfair.
It is, in a way, technically true that LLMs are stochastic parrots, but this undersells their capabilities (winning gold on the international math olympiad, and all that).
It's like saying that human brains are "just a pile of neurons", which is technically true, but not useful for conveying the impressive general intelligence and power of the human brain.
