In recent years--and especially since the 2016 presidential election--numerous media organizations, newspapers, and policy advocates have made efforts to help Americans become more careful consumers of the information they see online. In K-12 and higher education, the main approach has been to provide students with checklists they can use to assess the credibility of individual websites. However, the checklist approach is outdated. It would be far better to teach young people to follow the lead of professional fact-checkers: When confronted by a new and unfamiliar website, they begin by looking elsewhere on the web, searching for any information that might shed light on who created the site in question and for what purpose.
