Social Choice Theory

Social Choice Theory is a field of decision theory that studies how collective decisions are made from individual preferences. Arrow's Impossibility Theorem proves that no voting system can be simultaneously fair, rational, and universal. In AI governance, this means AI alignment via RLHF faces fundamental theoretical limits—no single AI model can perfectly represent all human values. This principle is critical for AI safety and ethical design, as it dictates the limits of AI-driven decision-making systems. Companies must account for these theoretical constraints when designing AI systems that impact diverse user groups, ensuring compliance with emerging regulations like the EU AI Act and Taiwan's AI Basic Law own frameworks.

Enterprise AI risk management using Social Choice Theory involves three key steps: First, stakeholder value-mapping to identify diverse user preferences, essential for compliance with the Taiwan Personal Data Protection Act (GDPR-aligned). Second, implementing AI decision-making aggregation rules, such as weighted voting or rank-aggregation, to ensure AI outputs align with institutional ethics. Third, establishing continuous monitoring of AI fairness metrics, such as the Disparate Impact Ratio (target range 0.8-1.25), to prevent discriminatory outcomes. For example, a Taiwanese bank deploying AI for loan approvals must use these principles to ensure the model doesn't violate the Fair Lending Act, mitigating regulatory and reputational risks.

Taiwan enterprises face three primary challenges: Lack of diverse datasets for AI training, regulatory ambiguity due to the pending AI Basic Law, and a shortage of AI ethics specialists. To overcome these, enterprises should: 1) Use synthetic data-generation techniques to represent diverse demographic groups; 2) Adopt the EU AI Act's risk-based approach as a global compliance benchmark; 3) Invest in cross-functional teams comprising AI engineers, legal experts, and ethicists. The priority should be establishing an AI Governance Committee within the first 90 days of AI deployment to oversee ethical compliance and risk-adjusted decision-making processes.
