Protect your sources. It’s the cardinal rule of journalism, and reporters hold this promise of confidentiality in the highest regard. Journalists will protect a source’s identity or withhold details of their conversations when revealing these truths would be morally objectionable or life-threatening to the source. Yet, some journalists have broken this sacred covenant when their own security or safety is on the line.

Ethical journalists act with integrity, seek the truth, and report on it. Telling a story of public interest requires transparency on who provided the information and how the reporter acquired it. Sometimes sources or experts will only speak with a journalist if the conversation is considered on background or deep background. The terms are part of a journalist’s reporting arsenal and should only be used when necessary. But some subjects, particularly those in positions of power, have used this type of attribution to their advantage.

Journalists have a long history of putting citizens first and holding power to account–and that shouldn’t change just because there’s a new owner on the masthead. Bill Kovach and Tom Rosenstiel go even further and say in a Neiman Reports post that this responsibility is “social obligation that can actually override their employers’ immediate interests at times.”

The personalization of news is a permanent feature of our information ecosystem that comes with some benefits and many challenges. News consumers are often overwhelmed by the amount of news they’re exposed to on a daily basis, and news personalization definitely helps by filtering that content. But algorithms that allow news outlets to curate information can lead to a filter bubble, polarization and extreme views.
