The Factual is a plugin that analyzes how credible a news article is based on the diversity and quality of its sources, the factual tone of the article's writing style, the expertise of the journalist on the topic based on historical focus, and the site reputation based on historical scores of every article on the site.
The Factual scores individual articles, so scores will vary within a publication. It will also recommend stories on a similar topic from both sides of the political divide to ensure that you are reading balanced sources.
Not only does it integrate with news websites, but it will also rate posts from designated news sites on Facebook and Twitter.
Their methodology is based on The International Federation of Library Associations.
The sites below generally review specific news stories and claims. Wikipedia, Google, Twitter, and LinkedIn can be used to look up quotes and research authors of articles to see their professional credentials.
Definitions used by Melissa Zimdar's Open Sources project that classifies websites for credibility.
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.
Extreme Bias: Sources that come from a particular point of view and may rely on propaganda, decontextualized information, and opinions distorted as facts.
Conspiracy Theory: Sources that are well-known promoters of kooky conspiracy theories.
Rumor Mills: Sources that traffic in rumors, gossip, innuendo, and unverified claims.
State-sponsored News: Sources in repressive states operating under government sanction. Propaganda.
Junk Science: Sources that promote pseudoscience, metaphysics, naturalistic fallacies, and other scientifically dubious claims.
Hate News: Sources that actively promote racism, misogyny, homophobia, and other forms of discrimination.
Clickbait: Sources that provide generally credible content, but use exaggerated, misleading, or questionable headlines, social media descriptions, and/or images.
Proceed With Caution: Sources that may be reliable but whose contents require further verification.
Political: Sources that provide generally verifiable information in support of certain points of view or political orientations.
Credible: Sources that circulate news and information in a manner consistent with traditional and ethical practices in journalism (Remember: even credible sources sometimes rely on clickbait-style headlines or occasionally make mistakes. No news organization is perfect, which is why a healthy news diet consists of multiple sources of information).
