Fighting Disinformation: How to Measure the Impact of Pre- and Debunking on Dutch Primary School Children’s Media Literacy? How to Measure the Impact of Pre- and Debunking on Dutch Primary School Children's Media Literacy?

To empower citizens against disinformation in a sustainable way, teaching media literacy is important, especially among young children, enabling them to use this competence throughout their lifetime. Prebunking and debunking are two different teaching methods to enhance media literacy and fight disinformation. Prebunking is a technique based on teaching people to recognize disinformation in advance so that they are aware of it. Debunking is characterized by refuting disinformation after the target group has been exposed to disinformation. To compare their impact, our empirical study conducted an exploratory experiment at two primary schools in the Netherlands in Spring 2024. One group of primary school children (10–13 years old) was exposed to a prebunking intervention (based on inoculation, a psychological approach directed against the disinformation manipulation techniques) while the other group was exposed to a debunking intervention (based on a traditional media literacy lesson). Both groups were questioned about the reliability of digital information (news items) to measure the effectiveness of prebunking compared to debunking.
