Social Media Trends and Public Opinion Dynamics in Port Harcourt

This study examined how social media trends influence agenda-setting and public opinion formation in Port Harcourt, Nigeria, with specific focus on the X platform (formerly Twitter). Anchored on the Agenda-Setting Theory, the research investigated three key questions: why Nigerian X users engage with certain trends over others, how frequently these trends shape opinion formation, and how influencers direct public discourse. Using a descriptive survey design, the study sampled 384 respondents from Port Harcourt's population of 3,688,308 through multi-stage sampling techniques. Data collection involved 323 valid questionnaire analyzed using frequencies and mean scores. Findings revealed that Nigerian X users engage with trends based on multiple factors: algorithmic visibility and frequency of appearance on timelines emerged as the strongest determinant, followed by entertainment value, emotional connection, and personal relevance, peer influence, and political importance. Social justice movements, particularly #EndSARS and #EndBadGovernance, dominated as the most prominent trends, followed by politics and governance and public health issues. The study demonstrated that X trends frequently influence opinion formation across social issues and political matters, health issues and popular culture, and economic concerns. Influencers emerged as powerful agenda-setters who determine topic visibility, frame discourse through strategic presentation, serve as thought leaders, and actively engage followers to shape public opinion. However, challenges persist regarding misinformation dissemination, echo chamber effects, and the quality of public discourse. The study recommends that influencers promote constructive dialogue, X platform collaborate with fact-checking organizations, and stakeholders encourage critical thinking among users to improve the quality and credibility of digital public discourse in Nigeria's evolving media landscape.
