Bias is the proper study of every discipline, and every intelligent person, no matter what their specialization or expertise. Journalism is the only discipline dedicated to convincing its audience that they are objective and beyond bias -- rather than it is the bias that is the filter of their perception and limits their understanding.
There is an interesting article in the Honolulu Star-Bulletin highlighting this discussion, entitled, "School video preaches tolerance," but it was only about tolerance for homosexuals and not tolerance for everyone in general, as one critic at the end was summarily dismissed. When one starts discussing tolerance only for homosexuals, or only for blacks, or only for Hawaiians -- that is not tolerance but bias.
So how these people can promote mutually contradictory points is what George Orwell -- a marginalized journalist of his times who predicted this growing danger of the media to blur relevant distinctions and foment its own unchecked biases -- called "doublethink."
Intelligence is manifested behavior and not potential that has yet to be manifested. A large part of this manifestation is what people get focused and involved with -- the significant or the trivial. In game strategy or war, one of the most effective strategies, is getting the opponent to fight every battle rather than just the significant ones -- so one's energies are dispersed too widely to be effective at any one -- that is the critical one.
