These websites make it their business to check facts on important or trending news stories. They are non-partisan, which means they are "not biased or partisan, especially toward any particular political group." (Courtesy Oxford New American Dictionary)
The International Fact-Checking Network (IFCN) is "a forum for fact-checkers worldwide hosted by the Poynter Institute for Media Studies. These organizations fact-check statements by public figures, major institutions and other widely circulated claims of interest to society.”
The Poynter Institute is "a global leader in journalism. It is the world’s leading instructor, innovator, convener and resource for anyone who aspires to engage and inform citizens in 21st Century democracies."
Their aim is to "teach those who manage, edit, produce, program, report, write, blog, photograph and design, whether they belong to news organizations or work as independent entrepreneurs. We teach those who teach . . . students in middle school, high school and college . . . And we teach members of the public, helping them better understand how journalism is produced and how to tell for themselves whether it’s credible."
