This case study presents the lessons learnt from a research practical experience involving triangulation. The benefit of triangulation as a research method was examined in a study with conflict-transiting communities where ethnic relations had gone badly and resulted in intense violence. Cross-checking information that participants provide to researchers and validating participants’ responses are keys to triangulation. The peculiarity of communities in some ethnic relations issues often are not the same and so have to be handled differently. The ways to conduct studies involving complex relations and excessive bigotry are highlighted with tips to ensure a credible research outcome.
