This led me down a bit of a rabbit hole. Related to this is what is sometimes known as the "Backfire Effect" which is the idea that a person's belief in something untrue will only be strengthened when presented with evidence to the contrary.

I had thought this was well established by experimental psychology, but now that I am looking into it it seems like the evidence is not nearly as strong as I thought and the effect may be very small or nonexistent.
