Credibility encompasses the perceived trustworthiness, expertise, and reliability of information sources. This topic covers psychological and social mechanisms underlying how people judge whether to believe information and sources, including factors like source reputation, source expertise, media type, presentation format, social proof, and heuristic shortcuts used in credibility assessment.

Notes
Credibility research bridges communication, psychology, and information science. Early work emphasized institutional gatekeepers and formal credentials, but internet-era research shows people increasingly rely on social and distributed forms of credibility assessment (peer ratings, reviews, peer networks) alongside traditional authority markers. Understanding credibility is foundational to misinformation research, since the first step in false-belief formation is often a judgment that misinformation is credible.
