Based on a shared lack of romantic and sexual relationships with women, the “involuntarily celibate” have congregated online in misogynistic cyberspaces to vent their personal issues, feelings towards women, and frustration about society. While their hostile attitudes and support for both online and offline violent rhetoric and actions have already been frequently studied, the question remains as to how the community pushes certain people towards adopting (extreme) misogynistic beliefs. Therefore, this ongoing project aims to further our knowledge of the community and its members, online misogyny, and radicalisation towards misogynistic extremism. For this purpose, the project will delve into the following elements: (1) the characteristics of people who identify as incels and join the community, (2) their reasons for joining and participating, and their experiences on these platforms, and (3) how the community contributes towards online misogynistic radicalisation by developing, sustaining, and spreading the incel ideology and online misogyny. The incel phenomenon will be studied from an interdisciplinary perspective shaped by literature on radicalisation, feminist scholarship on gender, masculinity and misogyny, (social) psychology, online communities etc., and combined with a mixed methods approach. The basis of this virtual ethnographic study is formed by non-participant observations on three forums, where a thematic analysis based on the writings of the members and a quantitative analysis of forum statistics will provide a view into the inner dynamics of the observed forums. This data in turn will shape the subsequent qualitative interviews and quantitative survey with self-identified incels, where specific themes that emerged during the first phase can be more deeply explored. By studying the incel phenomenon from various perspectives using several methods, and focusing on both personal and social factors, this study will shed light on the dynamics of online gender-based hate and radicalisation.
