Diffuse research refers to a broad and overarching field of study that encompasses a range of topics or phenomena that do not fit neatly into a specific category or discipline. This type of research typically involves exploring complex and diverse issues that may have multiple causes, effects, and implications. Examples of diffuse research areas could include interdisciplinary studies, cross-cultural research, or investigations into complex societal problems. Researchers in this area often draw on multiple disciplines and methodologies to gain a comprehensive understanding of the subject matter.
