There was some research recently that showed the same thing. People who are "dug in" on a topic, usually a political topic, will shut down when a person tries to persuade them of an alternative, but are much more open to hear the same arguments from AI and actually reconsider their position.

I believe this is a big reason why X-Ai was so important for conservatives to get off of the ground, they were afraid all the crazy would start wearing off if people asked the "woke" models for the truth.
