Q says to trust Barr but no one has ever specified what to trust.

When we say "trust person x", our brain processes it as they are trustworthy.

With Q because of how they post, there is not the connotation they are good. We should look at it in different ways. Perhaps Q meant trust Barr to be a traitor, or trust sessions to do the wrong thing....

Qs posts often time lack context for good reason. It's up to us to make sure we are looking at all possible angles.
