<p>Addressing persistent inequalities between advantaged and disadvantaged groups often requires public support for social policies aimed at reducing intergroup disparities. Previous research suggests that interventions emphasizing intergroup helping or similarity-focused contact can increase advantaged group members’ willingness to support social policies benefiting disadvantaged groups. However, the applicability of these interventions outside Western contexts remains underexplored. This study investigated whether exposure to video-based interventions promoting intergroup helping or similarity-focused contact increased policy support among advantaged Turks (<i>N</i> = 259) towards disadvantaged Kurds during the COVID-19 pandemic in Türkiye. Participants, recruited via convenience sampling through social media, were randomly assigned to intergroup-helping, similarity-focused contact, or a neutral control condition. Policy support was measured using scales assessing support for high- and low-cost social policies. ANCOVA analyses indicated that, compared to the control condition, both intergroup helping and similarity-focused interventions significantly increased support for high-cost social policies, while no differences were found for low-cost policies. Within the Turkish context, this finding implies that, despite prevalent ethnic tensions and structural inequalities, interventions emphasizing intergroup helping or similarity-focused contact can equally and effectively foster a common ingroup identity among advantaged group members, enhancing their willingness to endorse costly policies benefiting disadvantaged groups. Nevertheless, results should be interpreted considering potential sampling biases due to the recruitment method. Future research should replicate these findings with more representative samples and explore boundary conditions in different cultural settings.</p>
