Approche psycho-sociale des dégradations de symboles nationaux : conséquences sur les relations intergroupes, implication de l’identification et des patriotismes

Abstract : The aim of this thesis is to study the impact of national symbols’ desecration on intergroup relations and socio-psychological factors (identification and patriotism) that may moderate these consequences. Because they strengthen the cohesiveness, distinctiveness and cultural identity of a group, national symbols ensure a secure social identity. Based on social identity theory, we hypothesized that symbol desecration, even if perpetrators are ingroup members, would constitute a threat and thus provoke a diffuse pro-ingroup bias. Intergroup consequences could be moderated by rigid or conservative identification with the national group, i.e., blind patriotism. These issues are explored in four experimental chapters. The first three chapters examine implications of desecrating a national symbol and group identification on intergroup attitudes. On the whole, identification does not explain increases in pro-ingroup bias when symbols are harmed. However, context is determinant. The desecration of a national symbol by an ingroup member in an intergroup (sport competition) or intragroup context leads to strategies of intergroup (increase in pro-ingroup bias) or intragroup (increase in identification) defense, respectively. The fourth chapter shows that blind patriotism is a moderator of consequences of an ingroup national symbol’s desecration in an intragroup context. Higher blind patriots perceive more threat, resulting in an increased and diffuse proingroup bias. Contributions, limits and perspectives of this research are discussed.
