This study explores the role of logical principles as a scientific foundation in economics, highlighting how logic supports theory development, empirical analysis, and decision-making in this discipline. As the foundation of scientific methodology, logic ensures consistency, validity, and coherence in research, helping to avoid cognitive biases and logical fallacies that often arise in economic analysis. Using the Systematic Literature Review (SLR) method, this study synthesizes findings from various academic sources to explain the importance of logical principles such as deduction, induction, and probability in building economic theories and addressing challenges in modern economic research. In conclusion, the proper application of logic not only improves the quality of research but also the credibility of the resulting economic policies.
