Every website and news source has bias, meaning the publishers and editors make choices about what information to present based on their perspective. They also make choices about what information to believe and how to use words and images to tell a story.
Sometimes the information is incomplete or incorrect, which is misinformation. Promoting false information is called "disinformation." In any current event, there will be misinformation because of incomplete information or false assumptions. This is particularly common with information spread through social media, where people react quickly to real-time events.
Use these sources to understand the information you use and to evaluate its bias (underlying assumptions), perspective (worldview or conceptual framework), authority (how authoritative the sources are), and reliability (how close to true and accurate).
