The smarter you are, the less likely you are to change your mind on certain issues when presented with new information
In an adversarial setting -- e.g. in the middle of culture warfare -- this is an entirely valid response.
If you just blindly update on everything and I control what evidence you see, I can make you believe anything with arbitrarily high credence. Note that this does not necessarily involve any lying, just proper filtering.
That's just rationalization. Again, even in the context of a simple hypothetical example with very clear and unfiltered evidence, participants were not willing to change their minds. I suggest you look at the actual study.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
