This lesson and its accompanying seven-minute video introduce students to a professional fact-checker, who describes the methods and processes he employs to verify information that appears in news stories. The video explains which claims can be fact-checked, and why some sources are more reliable than others. How do fact-checkers engage in analysis of contemporary and historical claims? How do we distinguish between “bad facts” and “bad narratives” when critiquing media sources? Examine the tools that fact-checkers use to identify and interrogate claims, and put those skills into practice.
