Reflexivity involves questioning what is taken for granted and exposing the hidden assumptions, meanings and power relations that underpin particular understandings of 'reality.' This chapter discusses two forms of reflexivity. The first concerns the way reflexive practices serve to problematize the phenomenon under investigation, with the aim of unsettling more established versions of reality and generating alternative ways of thinking. The second is radical or self-reflexivity where researchers interrogate their own involvement in the production of knowledge by authoring reflexive texts and conducting reflexive research practices.
