I followed this story last night into a live youtube stream where the presenter asserted everything with an authoritative voice:

After bumbling his way through some half-hearted doxing attempts and watching her videos, he was smugly confident in his extrapolations of her psychological diagnosis, political affiliations, family history, &c. And his commenters formed a sycophantic chorus.

Ideology is the failure of a mental model to adapt to error. It's an inflexible coping strategy that rams all perceptions into presuppositions.

Its air of authority is evidence of the delusion, not of successful reality-checking.
