The key here is to be truth *seeking*. I'm not claiming you can actually find the truth, and sit on it and tell everyone they are wrong
I'm saying defining your task as a journalist as the deliberate *seeking* of the truth imposes a kind of direction that gives a kind of information-hygiene that protects you from many of the worst abuses that media can commit.
@Loukas @jayrosen_nyu From that perspective, it is indeed a valid definition, which arises another problem namely how many modern journalists (at least mainstream media journalists) actually seeking the truth, haha
