What does reduction refer to in research methodology?

Reduction in research methodology specifically pertains to minimizing the number of animals used in research without compromising the scientific validity of the results. This principle is part of the broader ethical framework known as the "3Rs," which stands for Replacement, Reduction, and Refinement. In this context, reduction aims to lessen the impact on animal subjects while still obtaining reliable data. By focusing on fewer animals, researchers can potentially reduce suffering and contribute to more ethical research practices.

This approach emphasizes the importance of designing experiments that yield the maximum amount of information from a minimal number of subjects. It encourages scientists to carefully consider their experimental designs and to strive for greater efficiency in data collection.
