Definitely agree with the calling other opinions into question thing. I try to use that to check myself whenever I'm listening to someone I think initially has a lot of good points.

There are a couple of topics where it for me shines through if people on the right politically will actually reflect deeply to find the "correct" answer, or whether they're willing to regurgitate every talking point of the right.

Likewise when people on the left know all the genuinely good arguments, but also subscribe to every single point of craziness from the woke left.

I'm always disappointed when good speakers turn out not to be good thinkers...
