We are a nonpartisan, nonprofit “consumer advocate” for voters that aims to reduce the level of deception and confusion in U.S. politics. We monitor the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases. Our goal is to apply the best practices of both journalism and scholarship, and to increase public knowledge and understanding.
FactCheck.org is a project of the Annenberg Public Policy Center of the University of Pennsylvania. The APPC was established by publisher and philanthropist Walter Annenberg to create a community of scholars within the University of Pennsylvania that would address public policy issues at the local, state and federal levels.

Hoaxy visualizes the spread of claims and related fact checking online. A claim may be a fake news article, hoax, rumor, conspiracy theory, satire, or even an accurate report. Anyone can use Hoaxy to explore how claims spread across social media. You can select any matching fact-checking articles to observe how those spread as well. We track the social sharing of links to stories published by two types of websites: (1) Independent fact-checking organizations, such as snopes.com, politifact.com, and factcheck.org, that routinely fact check unverified claims. (2) Sources that often publish inaccurate, unverified, or satirical claims according to lists compiled and published by reputable news and fact-checking organizations.
Hoaxy visualizes two aspects of the spread of claims and fact checking: temporal trends and diffusion networks. Temporal trends plot the cumulative number of Twitter shares over time. The user can zoom in on any time interval. Diffusion networks display how claims spread from person to person. Each node is a Twitter account and two nodes are connected if a meme (link to a story) is passed between those two accounts via retweets, replies, quotes, or mentions. The color of a connection indicates the type of information: claims and fact checks. Clicking on an edge reveals the tweet(s) and the link to the shared story; clicking on a node reveals claims shared by the corresponding user. The network may be pruned for performance.
We do not decide what is true or false. Not all claims you can visualize on Hoaxy are false, nor can we track all false stories. We aren’t even saying that the fact checkers are 100% correct all the time. You can use the Hoaxy tool to observe how unverified stories and the fact checking of those stories spread on public social media. We welcome users to click on links to fact-checking sites to see what they’ve found in their research, but it’s up for you to evaluate the evidence about a claim and its rebuttal.

PolitiFact is a fact-checking website that rates the accuracy of claims by elected officials and others who speak up in American politics. PolitiFact is run by editors and reporters from the Tampa Bay Times, an independent newspaper in Florida, as is PunditFact, a site devoted to fact-checking pundits. The PolitiFact state sites are run by news organizations that have partnered with the Times. The state sites and PunditFact follow the same principles as the national site.
