"Today's journalism ethics are the ethics of a profession serving yesterday's information-starved communities," he writes. "Today, we need a journalistic method that serves communities seeking truth and relevance within the abundance of information surrounding them."
He suggests journalists develop their own version of scientific methods to improve their standards to move from a medium of information to a medium of the arbiter of information.
