When Neighbourhood Norms Matter: Understanding the Drivers of Pro‐ and Anti‐LGBTI Actions in Türkiye

Despite the global rise of anti‐LGBTI policies, research examining the contextual drivers of cis‐heterosexuals’ action tendencies towards LGBTI remains limited. Across two studies, we investigated the role of local neighbourhood norms in Türkiye using a cross‐sectional multilevel design (Study 1; N = 488) and a preregistered experimental norm manipulation (Study 2; N = 198). Study 1 showed that perceived supportive norms were associated with greater pro‐LGBTI action at both individual and neighbourhood levels, and with lower anti‐LGBTI action at the individual level. Perceived opposing norms also predicted increased pro‐LGBTI action at the individual level. In Study 2, compared to control, supportive norms condition increased pro‐LGBTI action, whereas opposing norms increased anti‐LGBTI action. Compared to opposing norms, supporting norms also increased pro‐LGBTI action and reduced anti‐LGBTI action. Findings highlight the importance of local normative contexts in shaping intergroup action tendencies.
