Despite being recognised as the foundational process of an extremist group exit [Morrison, J. F., Silke, A., Maiberg, H., Slay, C., & Stewart, R. (2021). A systematic review of post-2017 research on disengagement and deradicalisation. Centre for Research and Evidence on Security Threats. https://crestresearch.ac.uk/download/3797/21-033-02.pdf], identity transformation is surprisingly under-investigated. This paper therefore explores how identity is represented in the exit process by examining ten autobiographies written by right-wing formers. The data were analysed using thematic analysis, and three themes were developed and named: ‘is this who I am?’, fatherhood, and reinventing the self. Drawing on social identity theory [Tajfel, H., & Turner, J. C. (1979). An integrative theory of intergroup conflict. In W. G. Austin, & S. Worchel (Eds.), The social psychology of intergroup relations (pp. 33–37). Brooks/Cole], the article proposes that emotionally laden cognitive openers can alter intergroup evaluation and social identity satisfaction. Certain cognitive openers, such as fatherhood, were seen to strongly influence the former’s self-categorisation and personal identity. The analysis also found that rebuilding an alternative identity after leaving the group took significant time and effort. The paper highlights the complexities of identity transformation during and after an extremist group exit and suggests that the process can involve changes to both personal and social identity structures.
