From what I’ve read, there are a few things that change people’s beliefs. Fact is not one of them. What your in-group believes is a big factor. So if we could murder fox news, we’d probably do the world a lot of good.

But the other thing that apparently can push people into reevaluating their beliefs? Horrific, personal, trauma. Someone who’s whole town was destroyed by climate change might be shaken up enough to rethink their world view. Maybe.

You could also maybe trigger the effect by beating the living shit out of a climate change denier, because being dragged out of their coal-rolling truck and being beaten so badly they’ll never walk again would be traumatic.
