“I’ll change my beliefs when I see it”: Video fact checks outperform text fact checks in correcting misperceptions among those holding false or uncertain pre-existing beliefs

Widespread concerns about the pervasiveness of misinformation have propelled one antidote to the center of scholarly attention: the journalistic fact check. Yet, fact checks often do not work as intended. While most fact checks are text only, a compelling theoretical argument can be made for using a video format instead. In this pre-registered experiment conducted in Germany (N = 1,093), we investigated whether using video versus text can improve fact checks’ ability to correct misperceptions about transgender women, cannabis consumption, migration, and climate change. Video fact checks outperformed text fact checks, with those holding false or uncertain pre-existing beliefs benefiting the most. We contribute to motivated reasoning theory the idea that visual information can override directional reasoning better than textual information, and that processing fluency is the mechanism by which this occurs. Our findings paint an optimistic picture for the ability of fact checks to debunk misinformation, especially for those holding misperceptions.
