I see what you mean. I'll try to give an example.

I tend to be skeptical of folks when I know they're incentivized monetarily, emotionally, or socially to believe a certain thing but I do my best not to discount them out of hand. I think most people have a tendency to write folks off completely when it's more useful to accept uncertainty. To know that a piece of information might be right even if it challenges my worldview. Unfortunately uncertainty is kinda hard work.

For instance, the US has a lot of incentive to make alternative economic systems seem awful. Anytime a pro US media source like Radio Free Asia says something negative about China. I have to accept that:

1. They've lied in the past
2. They're incentived to lie again
3. It's still possible they're telling the truth

I have to accept that balance.

This works well for situations that don't effect me personally. On the other hand, if there's a person who has a predatory reputation in my friend group, I don't have the luxury of giving them the benefit of the doubt. They are a present danger to myself and the people around me.
