Video or text? Evaluating the relative efficacy of different formats for fact-checking.
The research team, which included Factcheck.org co-founder Kathleen Hall Jamieson, presented a sample of 525 online respondents with a deceptive claim on the Keystone XL pipeline included in a political flyer. They were then presented either (a) a textual fact check of the claim (b) a humorous video fact-checking that claim (c) a non humorous video fact check (d) an unrelated humorous video of a baby singing (e) nothing at all. Belief in the deceptive claim fell more significantly among participants who viewed either fact-checking video than among those who read the article.
