The bias bar demonstrates the bias distribution of reporting on a given story.

For example, if 15 sources are reporting on a story, and only 10% of coverage is from right-leaning sources, it would indicate a lack of coverage from sources that typically report on stories that support a right-leaning narrative. If a story only has 10% coverage from left-leaning sources, it would indicate a lack of coverage from sources that typically report on stories that support a left-leaning narrative.

The messaging is intended to communicate that people who only read news from sources from one side of the political spectrum would have missed out on the story. This often happens when a story contradicts a source’s dominant political narrative.
