I think this is sharply correlated with what Tom Nichols' termed ['The death of expertise'](http://thefederalist.com/2014/01/17/the-death-of-expertise/ http://thefederalist.com/2014/01/17/the-death-of-expertise/) and how we tend to assign equal weight to all opinions, irrespective of the voice attached to them. Hence, we end up measuring volume/loudness rather than quality.
