Public attitudes toward immigrants and refugees are shaped by a complex interplay of psychological, social, and political factors. This thesis examines these attitudes in Ireland through both quantitative and qualitative approaches. The quantitative component utilises data from the Republic of Ireland arm of the COVID-19 Psychological Research Consortium (C19PRC) study, with a sample size of 1041 participants. It focused on key predictors of migration attitudes, including socio-demographic, political, psychological, and mental health variables. The findings indicate that socio-demographics, social dominance orientation, trust in the state, empathy, and conspiracy mentality are significant predictors of migration attitudes, while mental health variables do not show a similar association. The qualitative component comprises data gathered through semi-structured interviews with residents of Dublin, with a sample size of 21 participants. It explored how personal experiences, media narratives, and national identity influence public perceptions towards immigrants and refugees. The reflexive thematic analysis identifies five key themes, along with several subthemes: Awareness of Anti-Migrant Sentiment, Attitudes Toward Diversity, Barriers to Integration, Economic and Public Service Concerns, and Irish Identity. This study enhances the broader understanding of migration attitudes in Ireland and Dublin, underscoring the importance of policy interventions that foster social cohesion, address systemic inequalities, and challenge prevailing exclusionary narratives. The limitations of this study are also discussed, as well as implications for future research, policy development, and intercultural relations.
