This research paper explores the underrepresentation of Black American artists, particularly Black female artists, in American museums, examining its impact on social justice and democracy. Employing content analysis, the study focuses on major San Francisco art museums to assess how they represent minority artists. The literature review emphasizes the crucial role of art in fostering social justice and notes various efforts to address underrepresentation, such as increased spending on art by Black artists and museum initiatives to diversify collections. Identified research gaps include the need for larger sample sizes and exploration of socio-economic factors. Methodologies involve content analysis, case study research, evaluation research, and correlation research to analyze museum documents, exhibits, and diversity plans, aiming to determine the effectiveness of museum initiatives in promoting diversity and inclusivity.
