That's is a media-cerated myth. The myth came out in the 1920's,
Journalistic Objectivity Evolved the Way It Did for a Reason - TIME Magazine, November 5, 2018
Even that article aims to perpetuate the myth.
The function of the press as an institution is to manipulate the public for the advantage of the press's maseters, which is emphatically NOT the public.
People will get closer to the truth when they take the time to study and discuss. Our laxzy public does very little study, and is hamstrung by having a dearth of knowlegdable sources and teachers.
Lazy consumption of news in half hour teevee programs, followed by crticism of the press, that does nothing to advance on the truth. It does nothing more than repeat what we already know, the press is not a source of truth. it is a source of information, yes, but even THAT is often lies, and nearly 100% of the time is misleading inforamtion for various reasons, lack of context, cherry picked, or striaght up fiction.
Well, there’s that....
