Reduction is a research area in which scientists work to simplify complex systems or problems by breaking them down into smaller, more manageable parts. This process involves identifying the essential components or variables that are most important for understanding the system and focusing on them while disregarding less critical details. Reduction aims to provide simpler models or explanations that can help researchers gain a better understanding of complex phenomena and make new discoveries. This approach is commonly used in various scientific disciplines, such as physics, biology, and psychology, to study and analyze intricate systems and processes.
