This paper explores the integration of machine learning with adaptive theory in social science research, highlighting a methodological evolution crucial for understanding complex social phenomena. I examine the synergistic potential of combining machine learning's data-driven analysis with adaptive theory's iterative, flexible nature. The paper outlines the methodological fit of adaptive theory in social sciences, emphasizing its accommodation of complexity and contextual variability. I discuss the theoretical implications of incorporating machine learning, including its role in hypothesis testing and the development of social theories. The paper further navigates through the research process, illustrating how initial broad concepts refine into structured inquiries via inductive exploration and deductive forecasting using machine learning techniques. Finally, I address the challenges and opportunities presented by this integration, such as model interpretability and ethical considerations, while forecasting future research directions. This integration marks a significant step in enhancing the depth, dynamism, and responsiveness of social science methodologies.
