it's pretty obvious that denial is politically and personally motivated and that the deniers are performing motivated reasoning, not seriously misinformed.

CFAR mission isn't informing people but teaching them to reason well. Not holding wrong beliefs because of motivated reasoning is part of that of it.

Caring doesn't fix the problem of motivated reasoning. A person who believes that AI risk doesn't exists because they think that an FAI would be really awesome has no problem with not caring for humanity.

Even on the issue of climate change you have problems of motivated reasoning on both sides of the isle. A lot of the money invested into Green energy companies went bust because people didn't think well about the sector and where the money has the biggest impact.
