Fake news should not be confused with satire, bias, junk science or clickbait. Fake news is intentionally false, meaning there is no factual basis for this kind of news. To help you delineate fake news from other types of sources here are some helpful definitions:
Fake News: Sources that entirely fabricate information, disseminate deceptive content, or grossly distort actual news reports.
Satire: Sources that use humor, irony, exaggeration, ridicule, and false information to comment on current events.
Bias: Sources that come from a particular point of view and may rely on propaganda, decontextualized information, and opinions distorted as facts.
Junk Science: Sources that promote pseudoscience, metaphysics, naturalistic fallacies, and other scientifically dubious claims.
Clickbait: Sources that provide generally credible content, but use exaggerated, misleading, or questionable headlines, social media descriptions, and/or images.
