Research from various countries demonstrates that trust builds social cohesion and conflicts may be solved as a result. Many alternatives for reconciliation in various countries have been studied and introduced to Thailand. However, the implementation of a reconciliation policy in Thailand seems to be impossible without having the atmosphere of peace building and specifically, trust building. This study aims to measure trust and discuss factors that may be problematic for establishing social cohesion, explaining why the process of reconciliation cannot be successful without trust building. The data from the Social Quality survey conducted by King Prajadhipok's Institute in late 2009 was used. This study finds that Thai society is still fragile because of the decreasing trust among people as well as confidence in various institutions, particularly political institutions.
