The rapid advancement of artificial intelligence (AI) is transforming governance and decision-making processes across the world, with profound implications for democracy. AI offers promising opportunities to strengthen democratic decision-making by enhancing public service delivery, improving access to information, and enabling data-driven policymaking. Through AI-powered tools, governments can analyze large datasets to identify public needs, predict social challenges, and design targeted solutions, thereby increasing efficiency and responsiveness. Additionally, AI has the potential to expand citizen participation by supporting digital platforms for public consultation, deliberation, and feedback, making governance more inclusive and participatory. However, the integration of AI into democratic processes also presents significant threats. Algorithmic bias, opaque decision-making, and the misuse of AI for surveillance and manipulation can undermine fundamental democratic principles such as fairness, transparency, and accountability. The rise of deepfakes, microtargeted political advertising, and AI-driven misinformation campaigns has raised concerns about electoral integrity and the erosion of public trust. Furthermore, the concentration of AI expertise and control in the hands of a few private entities and governments poses challenges to democratic pluralism and equitable access to technology. This paper critically examines both the opportunities and threats posed by AI in the context of democratic decision-making. It argues that while AI can support more effective and inclusive governance, its unregulated or unethical use risks weakening democratic institutions and citizens' rights. The study emphasizes the urgent need for transparent, accountable, and human-centric AI governance frameworks that align technological advancements with democratic values. By fostering ethical AI development, promoting digital literacy, and ensuring public oversight, societies can harness AI’s potential while safeguarding the principles of democracy. The future of AI and democracy is deeply interconnected, making responsible AI integration essential for sustaining democratic integrity.
