A socio-anthropological theoretical framework of the so-called Grid-Group Cultural Theory provides a typological model for understanding and mapping of cultural biases (shared values and beliefs), corresponding social relations and strategic behaviours. The starting argument of this paper is that this model can be used to illuminate and investigate the socio-cultural differences in peacebuilding approaches as the four theoretical ideal-types of individualism, egalitarianism, hierarchy and fatalism, correspond to different peacebuilding approaches used by different international actors and in different post-conflict contexts. This typological understanding of approaches to peacebuilding enables also a theoretical analysis of socio-cultural viability of different approaches in different socio-cultural context. The final argument of this paper is thus that viable approaches to peacebuilding are those that are synchronized with the socio-cultural context, i.e., with the cultural bias, social relations and strategic behaviours used by the major social and political actors in the local society.
