In the Introduction we define what we mean by deliberation. We then turn to the concept of Deliberative Transformative Moments (DTM) and present the coding categories to get a handle at the concept. We explain why we use an interpretative qualitative approach and give justification why we focus our research on deeply divided societies and why we chose group discussions between ex-guerrillas and ex-paramilitaries in Colombia, Serbs and Bosnjaks in Srebrenica and police officers and local inhabitants in Brazilian favelas. We also show how our research fits the general literature on conflict resolution in deeply divided societies. To make the research transparent we have established a website with the records, transcripts and English translations of all the group discussions (www.ipw.unibe.ch/content/research/deliberation). Our coding resulted in high reliability.
