Media Bias Taxonomy

Media bias is not a single phenomenon but a set of distinct patterns that shape how information is written, framed, selected, and interpreted. Adapted from The Media Bias Taxonomy by Spinde and colleagues, this framework outlines four main categories of media bias, alongside a set of related concepts that intersect with bias research. Together, they offer a clearer way to understand how bias appears in news.

1. Linguistic Bias

Linguistic bias appears in word choice, phrasing, implication, and semantic structure. It includes connotation bias, epistemological bias, framing bias, linguistic intergroup bias, and bias by semantic properties.

2. Text-level Context Bias

Text-level context bias arises from how information is presented within a specific article or passage. It includes phrasing bias, spin bias, and statement bias.

3. Reporting-level Bias

Reporting-level bias appears through editorial patterns of attention, omission, and selection across coverage. It includes coverage bias, proximity bias, and selection bias, also known as gatekeeping bias.

4. Cognitive Bias

Cognitive bias concerns how readers process media information through prior beliefs, identity, and selective exposure. In the taxonomy, it includes selective exposure and partisan bias.

Related Concepts

The paper also identifies related concepts that cannot be assigned exclusively to a single bias category. These include framing effects, hate speech, sentiment analysis, and group bias, which encompasses gender, racial, and religion bias.
