There’s no going back. Journalists now have to operate in a world where no statement, however trivial, will be completely secured from public gainsaying. At the same time, public production of speech, not just consumption, means that the policing of ethical failures has passed out of the hands of the quasi-professional group of journalists employed in those outlets, and has become another form of public argument.
This alters the public sphere in important ways.
The old days, where marginal opinions meant marginal availability, have given way to a world where all utterances, true or false, are a click away. Judgement about legitimate consensus is becoming a critical journalistic skill, one that traditional training and mores don’t prepare most practitioners for.
Journalists identify truth by looking for consensus among relevant actors. For the last two generations of journalism, the emphasis has been on the question of consensus; the question of who constituted a relevant actor was largely solved by scarcity. It was easy to find mainstream voices, and hard to find marginal or heterodox ones. With that scarcity undone, all such consensus would be destroyed, unless journalists start telling the audience which voices aren’t worth listening to as well.
A world where all utterances are putatively available makes “he said, she said” journalism an increasingly irresponsible form, less a way of balancing reasonable debate and more a way of evading the responsibility for informing the public. Seeking truth and reporting it is becoming less about finding consensus, which there is simply less of in the world, and more about publicly sorting the relevant actors from the irrelevant ones. They can no longer fall back on “experts,” as if every professor or researcher is equally trustworthy.
