The Supremacy of Bias: Identifying Barriers to Communication through Social Media Exchanges

Failures of communication and understanding are a persistent feature of public discourse. This book argues that many of these failures arise from value-protective denial: the tendency of individuals to avoid, ignore, or reject information that threatens beliefs supporting their values. Because many activities and perceptions of reality depend on these beliefs, contradictory information can produce a threat response that motivates resistance to evidence and logical contradiction. The book describes a condition referred to as the supremacy of bias, in which the protection of belief-supporting values is prioritized above truth, learning, or intellectual consistency. When this condition is present, individuals maintain positions despite unresolved contradictions or the absence of supporting evidence. The argument is developed through a series of analyzed social-media exchanges that illustrate recurring patterns of reasoning failure, including authority-based belief formation, the treatment of opinion as fact, and resistance to arguments that challenge existing beliefs. These cases demonstrate how value-protective denial obstructs learning and prevents the establishment of shared factual understanding. The broader implication is that bias-driven resistance to challenging information undermines both individual reasoning and collective decision-making in democratic societies.
