Specifically, it examines whether IWAH mediates the link between social dominance orientation (SDO) and intergroup anxiety.Design/methodology/approachThe sample included 304 adults from T & uuml;rkiye (61.2% male; age range: 18-64, M = 29.83, SD = 8.38), who completed an online survey including the SDO, intergroup anxiety and the IWAH scale.FindingsResults showed that higher SDO was linked to lower IWAH and greater intergroup anxiety. In contrast, higher IWAH was associated with reduced intergroup anxiety. Mediation analysis confirmed that IWAH significantly mediated the relationship between SDO and intergroup anxiety.Originality/valueThese findings suggest that fostering a broader human identity may buffer the negative effects of social dominance on intergroup relations. This study contributes to research highlighting IWAH as a potential pathway to reducing intergroup tensions and promoting global solidarity.eninfo:eu-repo/semantics/closedAccessIntergroup relationsIntergroup anxietyIdentification with all humanitySocial dominanceArticle10.1108/MHSI-09-2025-02432-s2.0-105027382201Q3WOS:001640489600001Q3
