Like they used to?
Journalism had a pretty strong code of conduct and drive to publish the facts. They couldn’t get it right all the time, but they had a stake in doing the best they could and not losing their reputation.
The truth of things doesn’t tend to come out in time. We know the truth about many things now, but after the window in which a change could be made was obfuscated and stopped.
Facts coming out when it is convenient to the people withholding them is not a success. If they come out at all.
The old system of journalism did a surprisingly good job, until people gave up on playing by the rules and decided to play by the trappings of journalism.
Reputation matters to the center and the left of the information ecosystem today. The right has connected its media to its politics entirely, to create a propaganda machine. Part of its routine is to state that journalism and the left are biased, and don’t want to deal with the truth, and then shoehorning their narrative into it.
