Terrorist groups have integrated social discourse into their narratives to exploit public fear. The COVID-19 pandemic has provided an opportunity to measure how ISIS modified narratives, stimulated group communication, reinforced enemy hatred, and employed new mobilization/recruitment strategies. Using Significance Quest Theory, this study examines ISIS’s Twitter activity related to COVID-19 ( N = 630,201) and how the group leverages the psychological effects and the social disruption. This study employs a two-stage analysis of tweet sentiment and emotion with a statistical analysis of retweet-motivating factors to explore how ISIS manages its narrative, needs, and network. Results show content with higher negative sentiment scores had more retweets across all sample sets. Insights include deeper understanding of extremist activity and group adaptation to external changes.

The transfer of power stemming from the 2020 presidential election occurred during an unprecedented period in United States history. Uncertainty from the COVID-19 pandemic, ongoing societal tensions, and a fragile economy increased societal polarization, exacerbated by the outgoing president's offline rhetoric. As a result, online groups such as QAnon engaged in extra political participation beyond the traditional platforms. This research explores the link between offline political speech and online extra-representational participation by examining Twitter within the context of the January 6 insurrection. Using a mixed-methods approach of quantitative and qualitative thematic analyses, the study combines offline speech information with Twitter data during key speech addresses leading up to the date of the insurrection; exploring the link between Trump's offline speeches and QAnon's hashtags across a 3-day timeframe. We find that links between online extra-representational participation and offline political speech exist. This research illuminates this phenomenon and offers policy implications for the role of online messaging as a tool of political mobilization.
