Media Bias

Short answer: A pattern where a news outlet consistently frames events to favor one political worldview.

Media bias is the term for systematic, repeated framing choices in a news outlet's coverage that favor one political worldview. Optics News uses outlet-level bias labels from Media Bias / Fact Check (MBFC) as context, but its core product is article-level framing comparison — showing what changed in the headline wording on this specific story, not a static judgment about the outlet. Bias labels are useful context; they don't override the actual wording.
