What constitutes 'research rigor'?

Research rigor refers to the strict adherence to established scientific methods throughout the research process, which ensures the reliability and validity of the study findings. This means that the research is conducted in a systematic and controlled manner, employing methods that are recognized and accepted within the field. By following these scientific methods, researchers can minimize bias, enhance reproducibility, and strengthen the credibility of their conclusions.

While incorporating diverse methodologies, engaging participants, and analyzing various data types are all valuable aspects of research, they do not, by themselves, ensure the robustness of the findings without rigorous application of scientific principles. Rigor is fundamentally about maintaining high standards of quality and integrity in the research process, which is achieved primarily through the stringent use of scientific methods.
