Turning Opposition into Support to Immigration: The Role of Narratives

The way we collectively discuss migration shapes citizens' perceptions of migrants and their influence on our society. This paper investigates whether a narrative about the positive impact of immigrants on the hosting economy affects natives' behaviour towards migrants. To shed light on the underlying mechanism, we present a simple theoretical framework that models the relationship between beliefs, attitude and behaviour and identifies the sequential channels through which a narrative might be useful in changing attitude and behaviour. We test its predictions through an online survey experiment, where we deliver UK natives a favourable narrative about migrants. Treated subjects revise their beliefs about migrants and exhibit significantly more positive self-reported attitudes and more pro-migrant behaviour. Moreover, they update beliefs in a way that gives support to the existence of confirmation bias.
