Yes.  It turns out that if you try to get really specific about what _safe_ or_effective_ means, you run smack into the full complexity of the universe.  

Stuff that seems simple ("define _safe_") is surprisingly not simple.

The Loss of Shared Facts

Undisciplined

> It's a tough question.  "Covid vaccine is safe and effective."  Should this have been a shared fact, or not?

I think first you need to define "safe" and "effective" since ime, people talk past each other all the time and don't realize or don't care. What one sees as safe isn't safe for the other. Same for effectiveness and basically everything. I think this is also what @Undisciplined mentioned with shared facts vs shared conclusions.

This is definitely related to your argument about humility. It seems like we're not trying to convince others anymore, we're trying to convince ourselves (and our tribe if we blast our arguments into a digital space seen by million followers) that we're not wrong.
