This report presents the findings of an EDMO BELUX survey conducted in Spring 2022 to gain insight in the spread of disinformation among Belgian and Luxembourgish populations. We study exposure to, belief in, perceived causes of and solutions for disinformation in four regions—Flanders, Wallonia, Brussels and Luxembourg—with a representative sample of N=1,466 respondents. The findings of our survey tell a cautionary tale. Citizens in Belgium and Luxembourg are exposed to disinformation, especially the youth, social media users and politically interested. Belief in disinformation is more prevalent amongst younger citizens, and those who hold general conspiracy beliefs, while also being more trusting of media and politics. We also find evidence of a link between affective polarization and belief in disinformation in Belgium and Luxembourg.
