We live in an ethical epoch when editors at BuzzFeed and Politico have no scruples when a reporter sleeps with a prime source on her beat, after which she lands a prized New York Times job, at the very top of the journalism food chain.

Not that flexible conflict-of-interest standards are anything new. Ben Bradlee, as lauded as any journalist of his era, exploited a close friendship with President John F. Kennedy when he was Newsweek’s Washington bureau chief, giving fits to his competitors at Time. Bradlee was covering events that, one could argue, that he had helped shape in his conversations with Kennedy.

In 2018, such stuff matters more than ever, given the low esteem of “mainstream media” performance. The latest evidence comes in a survey reported June 11 by the American Press Institute, The Associated Press and NORC at the University of Chicago.

We learn that 35 percent of Americans have a negative view of news organizations, and 42 percent think news coverage veers too far into commentary, while 63 percent want to get mostly facts alongside limited analysis. Importantly, 42 percent don’t understand how the use of anonymous sources works and 68 percent say the media should offer more information about story sources.

President Donald Trump’s frequently fake “fake news” attacks on reporters, of course, continually involve complaints about unnamed sources. For sure, the Washington press corps, which makes such lavish use of anonymous sources in coverage critical of the Trump administration, must do everything possible to maintain accuracy and fairness.

Once upon a time -- in 2005 -- the staff Credibility Group formed in the wake of the horrid Jayson Blair scandal advised New York Times colleagues in a report titled “Preserving Our Readers’ Trust [.pdf here].” It warned that the daily should “keep unidentified attribution to a minimum” and “energetically” enforce limits across the board -- in hard news, features, magazine sections, and with copy from the growing number of freelance contributors.
