"I like pizza" is an opinion. "I can read your thoughts" is a factual claim. We can test factual claims.

  Sure, and "I can hear the ghosts around me" is not, and it's a waste of time for anyone trying to prove or disprove this opinion.

    Which is fine, but often the claim is "The thing in this picture is a ghost." That's easily testable.
