Two complaints do not prove balance
Opposing partisans can experience the same coverage as biased against their own side even when they agree on what appeared
Premise
A disputed report can attract mirror-image accusations of bias from opposing groups. The Hostile Media Effect explains how people with strong positions may sincerely experience the same coverage as unfair to their own side. The disagreement can persist even when the audiences agree about the statements, sources, and evidence the report contained.
Robert Vallone, Lee Ross, and Mark Lepper introduced the phenomenon in 1985 through research on reactions to coverage of the Beirut massacre. The framework concerns perceived bias, not deception or direct attitude change. It adds an essential diagnostic distinction: what the message actually did and how audiences with different stakes perceived it are separate questions that require separate evidence.
