The ‘involuntary celibate’, or (predominantly) men who have been unable to find romantic or sexual relationships with women despite desiring to, have come together in the online incel community. Though initially supportive in nature, the community has become a hotbed for (violent) online misogyny. This exploratory virtual ethnographic research focusses on the nature of the incel community and its members, and how the community plays a role in online misogynistic radicalisation. To this end, this paper applies Bayerl and others’ Radicalisation-Factor Model and its four interlinked factors – the individual, the environment, the radical groups and ideology, and technologies – to the incel community. This adjusted framework finds its basis in existing insights from the literature on online radicalisation, social psychology, gender, masculinity, and misogyny, and is further supplemented by insights from non-participatory observations on incel forums. By approaching the incel phenomenon from different perspectives, this framework has the aim of providing a holistic understanding of the incel community as well as highlighting the importance of the interplay of various individual, ideological, contextual, and technological features in the process of online radicalisation.
