We present a theoretical and epistemological reflection on Forum Theater’s potential as a Research Tool. Our presence on social action and research has led us to a double reflection on qualitative research’s limitations on the affect studies and the Forum Theater’s potential as a research tool to tackle research about affects. After some specific experiences in action research (qualitative research on romantic love and gender violence, and the creation process of the Forum Theater “Is it a joke?”), we explore Forum Theatre’s possibilities as a research tool in the feminist epistemology framework.
