A small fraction of online actors now exerts outsized influence over what the public sees, believes, and argues about. In a new short review paper, we trace how social media influencers can turn fringe claims into viral narratives—often by exploiting a feedback loop between influencers, algorithms, and crowds. As such, the modern information environment enables a tyranny of the minority: extreme and coordinated voices dominate attention, distort perceived social norms, and create a “funhouse mirror” version of public opinion that makes fringe positions look common and conflict look inevitable. We synthesize emerging evidence that a tiny number of highly active users drives a disproportionate share of misinformation and toxicity, and explain how platform incentives reward moralized, identity-salient, and emotionally charged content. We conclude by outlining pragmatic responses—individual, institutional, and policy-level—and by highlighting how generative AI could either accelerate bespoke realities or help rebuild shared understanding, depending on how these systems are designed and governed. osf.io/preprints/psyarxiv/tj… We (@PillaiRaunak & @steverathje2) reviewed @noUpside's fantastic book "INVISIBLE RULERS" and connected it to the research we have been doing on this topic for the past decade.
