Artificial intelligence (AI) is a concept based on the idea of creating intelligent computer programs similar to human intelligence by examining human intelligence. Recognizing and introducing the AI one of the most striking subjects of today and attracting the attention of public policy makers and practitioners by elaborating the developments and reflections of AI on the public administrations and policies constitutes main purpose of this study. In this context, the study examined the conceptual framework of AI in the light of the previous literature and researches and assessed the types, the historical development process, and the future. To shed lights on the reflections of AI in public administration and policies, the contribution of H. Simon, the Nobel Prize winning public administration scholar and influential since the beginning of his AI studies, and the impacts of AI practices on the main processes of public administration and policies like decision making, agenda setting, policy making and policy implementation in providing public services were evaluated. Examples of public policies with AI implementations in the public sector are included. It is concluded that AI will reduce the significant workload, increase efficiency and effectiveness, ensure timely better decisons especially in health, transportation, security and many similar public services, but it is ineveitable and necessary to specialize in AI in order to benefit greatly from this area and to prevent the probable risks.
