Phatthanakit's research focuses on social and cross-cultural psychology, specifically focusing on culture, identity, beliefs and well-being. Within his PhD research, he is studying cultural differences in just world beliefs (e.g. belief in a just world, immanent justice reasoning). There are previous studies examining just world beliefs in Western countries but not much research examining these concepts in some other parts of the world.
