In recent years, men identifying as involuntary celibates, or 'incels,' have been involved in serious incidents of violence against women. This group is characterized as a poltical sub-culture or onlinecommunity, marked by misogyny and driven by emotions such as resentment, shame, and revenge. The research on online incel communities is expanding, revealing their promotion of sexist, anti-feminist, and pro-violence worldviews, along with hegemonic and toxic forms of masculinity. A notable feature of the incel community is its intricate 'theoretical framework' used to elucidate the plight of its members. Within this framework, incel men are depicted as voiceless, excluded victims and losers in the (hetero)sexual market. This marginalization is atributed to their perceived biological inferiority and increased subjugation of men within a context shaped by hegemonic feminism. While existing research has extensively studied the content of incel theorizing, litle atention has been devoted to understanding how the incel community constructs its worldview. Our article aims to fill this gap by examining the incel worldview through a sociology of knowledge lens. A netnographic study of the digital incel forum Incels.is reveals how users establish their knowledge claims and the sources and methods they employ. Additionally, we explore the implicit or explicit epistemic paradigms at play, emphasizing the interactions and tensions between different paradigms. Notably, we investigate how incels leverage both conventional scientific principles and personal experiences, mirroring feminist approaches, to make claims about societal structures.
