The guy is a 'normal'.  He ultimately places his confidence in the inherent and relative 'goodness' of the establishment.  Part of the reason for this is that he rejects even considering alternate hypotheses which vary from mainstream conceptions of reality.  They are immediately labeled 'conspiracy theories' and thus can safely be rejected out of hand.  Gavin and most of the people who brought resources (financial, technical, etc) to the table are trained in the same way and cut from the same cloth.  Their reasons for getting involved in the first place vary, but they can be relied upon to follow certain fairly well directed paths as they navigate through the wilderness.
