The spectrum is based on trust.  

Science is trust in the scientific method plus your ability to carry it out alone.  Consensus is trust in some method of discerning truth from a collection of votes.  Democracy is accepting truth from a collection of votes alone.  Trust is believing a truth from a single vote alone

The pursuit of truth must live on that spectrum somewhere.  But it's moot, if the "meta-truth" is something outside that spectrum, in which case, the pursuit is pointless 😏
