The theoretical ability to falsify something (or to prove it) has no bearing on the realities of propaganda, extensive domain knowledge or the lack thereof, and how such positions are ultimately arrived at.

Namely, trust in the institutions.

How many facts that form the bedrock of your worldview have you, personally, verified? Have you, personally, walked down the chain of evidence for certain scientific (i.e. falsifiable) claims and personally attempted to falsify them?

I didn't think so.
