Examples include bias introduced by the ownership of media, including a concentration of media ownership, the subjective selection of staff, or the perceived preferences of an intended audience.

The Cochrane Risk-of-Bias Tool defines detection bias as the result of “systematic differences between groups in how outcomes are determined”. ⁴. This bias (also called observer, ascertainment, or assessment bias) occurs if knowledge of a patient's assigned strategy influences outcome assessment.

Another way to help overcome media bias is to read stories from multiple sources. For example, after a political debate, read multiple articles about the debate from sources ranging in affiliations. This way, you don't solely rely on information coming from one end of the political spectrum.
