Authority
From Tardis Wiki, the free Doctor Who reference
The Second Doctor told Zoe Heriot that logic merely enabled one to be wrong with authority. (TV: The Wheel in Space)
In early 2006, the webmaster of Who is Doctor Who? felt that "no one in authority will even start to take these sightings of Rose and the Doctor seriously - despite the WEIGHT of EVIDENCE." (PROSE: Rose sighting confirmed)
