“…Therefore, narratives have been proposed as a useful tool to address sensitive subjects, which may otherwise resist cognitive elaboration because of conflicting beliefs and/or lack of interest amongst the audience [Avraamidou and Osborne, 2009;Mazzocco et al, 2010;Slater and Rouner, 2002]. Moreover, because their cause-effect structure, narratives are intrinsically easier to remember than expository arguments [Dahlstrom, 2014;Graesser, Olde and Klettke, 2002] and the changes of beliefs induced by narratives appear to increase over time, the so-called 'sleeper effect' [Appel and Richter, 2007]. Finally, several studies show that these effects are resistant to various forms of manipulation [Appel and Richter, 2007;Green, 2004;Green and Brock, 2000]: unless the persuasive intent of a narrative is made explicit [Moyer-Gusé, 2008] or the message is subjected to an active scrutiny [Marsh, Meade and Roediger, 2003], narratives seem to be largely assimilated as 'facts' even when explicitly labelled as 'fiction' [Gerrig and Prentice, 1991;Gilbert, 1991;Green and Brock, 2000;Marsh, Meade and Roediger, 2003], and the message they carry can have long-lasting effects on the beliefs and behaviours of the reader.…”
