This research consists of an analysis based on a Discursive Psychology perspective of how Chileans talk about recent past. The data are focus group discussions produced in 2005 and 2006. The 11 September 1973, Chilean military overthrew socialist government of. Salvador Allende, who had been elected president in 1970. The military installed first a junta and then a military government headed by General Augusto Pinochet. The military regime, which became known for tactics of political repression including assassination, torture and exile, remained in power until 1990, when Pinochet, having lost popular support (according to results of a national plebiscite), returned country to civilian rule. Since then, Chile has had four democratically elected presidents, none of whom has been able to avoid dealing with the legacy of past. Among Chileans, there is no consensus regarding how to name, describe or explain the events leading up to and during military regime. On contrary, since day of the coup, opposing versions of events have been sustained by those who supported the Allende government and those who supported coup. The controversies about 11 September 1973 itself, as well as antecedents and consequences of what happened on that day, are still valid concerns for Chileans. These concerns have been studied under moniker of collective or social memory, as attempts to explain the difficulties Chileans have encountered in coming to terms with legacy of past. The most frequent explanations for lack of consensus about truth of what happened in Chile have been based on an appeal to memory processes, shaping a debate about past as well as about legitimate sources of knowledge of past. My research explores in detail discursive and rhetorical devices (handled by participants of several focus groups) by which debate is explainable as result of a systematic and methodical use of language of polarisation.
