Traditional journalism values a focus on news reporting that is fair and impartial, guided by principles like truth, verification and accuracy. But those standards are not observed across the board in the “news” content that people consume.

Tim Groeling, a communications professor at the University of California Los Angeles, said some consumers take too much of the “news” they encounter as impartial.

When people are influenced by undisclosed political bias in the news they consume, “that’s pretty bad for democratic politics, pretty bad for our country to have people be consistently misinformed and think they’re informed,” Groeling said.

If undisclosed bias threatens to mislead some news consumers, it also pushes others away, he said.

“When you have bias that’s not acknowledged, but is present, that’s really damaging to trust,” he said. —Poynter
