In Chapter 1 we set the historical context in which we did our research in the deeply divided societies of Colombia, Bosnia-Herzegovina and Brazil. We describe how we selected the participants for our discussion groups, which was done as randomly as possible. We took great care to follow strict rules of research ethics for the safety of the moderators and the participants. The discussions took place at safe locations. The moderators did not raise sensitive questions about the past involvement of the participants in war actions and violence in general. The only topic for discussion was ways for more peace and a better life. For the records on our website the voices of the participants were altered , and for the transcripts the names were changed. Therefore the confidentiality of what was said in the discussions was secured.
