Closing the Visibility Gap: A Design Science Approach to Algorithmically Competitive Counter-Speech

A recent integrative review identified the Visibility Gap as the structural discrepancy between the epistemic quality of counter-speech and its algorithmic competitiveness in platformised information environments. This article addresses the gap through design science research. Drawing on the Bystander Effect (Latané and Darley, 1970), social proof theory (Traberg, 2025), Population Intelligence (Tatham, 2015), the chronos/kairos distinction (Miller, 1994), the regulatory-theoretical diagnosis of the Public Discourse Paradox (Bassan, 2024, 2025), and cognitive warfare theory (Rushing et al., 2026), I derive five design principles for counter speech that combines verification capacity with algorithmic reach: platform-nativity, com municative plurality, temporal competitiveness, epistemic integrity under optimisation, and transparent automation. I present an artifact instantiating these principles through a four layer architecture integrating automated detection, persona-based intervention, embedded micro-inoculation, and adaptive evaluation. The artifact uses Thompson Sampling to op timise communicative delivery while structurally excluding factual content from the opti misation space. Evaluation through expert review and computational simulation supports the theoretical coherence of the design, provides preliminary evidence that the immutable constraint architecture resists reward poisoning under controlled conditions, and identifies persona authenticity and the tension between temporal competitiveness and human oversight as primary risks for field deployment. The central finding is that verification capacity and algorithmic reach, while analytically independent, are operationally coupled: achieving algo rithmic competitiveness imposes constraints that interact with verification standards. The article contributes to scholarship on counter-speech, platform governance, and information disorder by demonstrating that the Visibility Gap is a design deficit rather than a knowledge deficit, and that principled design within a regulatory frame that legal-theoretical analysis has independently diagnosed can address it.
