Impact of Social Media in Shaping Public Opinion in Nigeria: A Theoretical Review

Abstract

This study examines the impact of social media platforms such as Facebook, Twitter/X, Instagram, and TikTok in shaping public opinion within Nigeria’s socio-political context. The research problem emerges from the increasing influence of digital media in amplifying voices, framing issues, and mobilizing citizens, yet with limited understanding of its dual effects on opinion formation. Using a desk research approach, the study draws insights from relevant communication and sociological theories including Agenda-Setting, Framing, Spiral of Silence and Uses and Gratification. The objectives are to clarify key concepts, evaluate theoretical strengths and weaknesses and link them to the Nigerian digital experience. Findings reveal that while Agenda-Setting and Framing theories emphasize media’s power in issue salience and meaning construction, they understate audience agency. Similarly, the Spiral of Silence highlights the fear of isolation but struggles to fully explain online anonymity, whereas Uses and Gratification stresses user agency but overlooks structural inequalities in media access. The study concludes that despite these limitations, Framing Theory provides the strongest explanatory power for understanding how Nigerian social media users construct narratives and influence collective opinion. Thus, the research contributes to deepening communication scholarship in Africa by situating global theories within local realities.
