It's the fallacy that something must be true, because an authority figure or expert sais so. I've been hearing this fallacy quite a lot and don't remember it being used to prove points which I personally believe to be true. Could it be, that the people trying to convince others of this point of view have a difficult time themselves believing their own claims?
