["Political Psychology, Volume 47, Issue 3, June 2026. ", "\nAbstract\nThe proliferation of conspiracy theories online has tangible offline consequences, both on an individual and collective level. Conspiracy narratives have been associated with reduced belief in democracy, the rise of populist parties, and can act as a radicalization multiplier in such contexts. These narratives capitalize on pre‐existing beliefs and grievances and add urgency to act through a narrative of imminent danger. Previous research has proposed that belief in conspiracy narratives is driven by unfulfilled psychological needs such as existential threat, epistemic motives, and social motives and calls have been made to examine conspiracy belief as a form of affective community investment. In the present research, we explored how conspiracy narratives address grievances and psychological needs through a 1‐month digital observation of conspiracy‐related YouTube videos. We performed an LDA topic model analysis of 102 videos and 455,738 comments and qualitatively examined 24 videos and 1200 comments using an abductive approach. This study validated and extended existing models of conspiracy beliefs, highlighting how conspiracy narratives address and amplify grievances and psychological needs in both official content and community‐generated discourse. This research contributes to a deeper understanding of the mechanisms underlying the spread and impact of conspiracy theories in online environments.\n"]
