Rhetoric of Social Networks: Virality and Persuasion

New Rhetorical Conditions

Digital social networks have created radically new rhetorical conditions. The audience is not gathered before an orator, but dispersed, global, heterogeneous. Speed is not measured in days until a newspaper is released, but in seconds until the content spreads. Interactivity means the audience responds, comments, "likes," and shares.

"Virality" is the main goal in the rhetoric of social networks. What makes content viral? Jonah Berger's research ("Contagious", 2013): six principles of virality—social currency (make me interesting), triggers (remind me of something relevant), emotions (high arousal: anger, awe, anxiety—not sadness or calm), public observability (visible to others), practical value, narrative (story, not information).

Platform algorithms optimize "engagement"—which correlates with emotional arousal. This creates a systematic advantage for content that is conflictual, simplified, and emotionally charged.

Rhetoric of "Brevity"

Twitter/X (280 characters) created rhetoric of radical brevity. This is a rhetoric of slogans, not arguments. "A slogan beats a paragraph" in this environment. This is not neutral: complex positions cannot be expressed in 280 characters without simplification.

"Threads" are an attempt to bypass this limitation. But threads are read less often than single tweets. The attention economy works against argumentation.

TikTok—rhetoric of image and sound. 15–60 seconds of video. This is closer to television advertising than traditional rhetoric. "Capture attention in the first 3 seconds" is the content production rule. This is rhetoric of first impressions.

Question for Reflection: How do you adapt complex professional arguments for short formats (presentations, social networks, elevator pitch)? What is inevitably lost, and how can you minimize this?
