Data from a national online survey of 1010 respondents during the 2024 American campus protests show that hostile media perception fueled strategic social media activity – strengthening in-group bonds and disengaging from opponents. Additionally, conspiracy beliefs moderated these effects, intensifying or reducing the impact of hostile media perception on polarized social media behavior, depending on belief strength.enHostile media and friendly chambers: Social media polarization and the 2024 U.S. campus protestsPeer Reviewed Journal Article10.1080/08838151.2026.2642912
