Personal narratives to improve attitudes towards stigmatized immigrants: A parallel-serial mediation model

This work addresses the study of factors that increase the persuasive efficacy of testimonial messages aimed at improving intergroup attitudes. The results of two online experiments (N = 840) on the effect of empathy with, and similarity to, the protagonist in personal stories designed to improve attitudes towards immigrants are presented. In both studies, participants were given instructions to induce a certain exposure condition (empathy vs. an objective or distanced perspective) immediately before reading a narrative whose protagonist was an immigrant with high or low similarity to the audience. The results of mediation analysis show that both empathy and similarity increased identification and narrative transportation, which in turn reduced counterarguing, thus resulting in a more positive attitude towards the outgroup and lower threat perception. The results are discussed in the context of research on narrative persuasion and the design of campaigns to reduce racism and xenophobia.
