A paradigm shift refers to a fundamental change in the beliefs, assumptions, and methodologies within a specific scientific or academic field. This shift occurs when new discoveries, research findings, or perspectives challenge the existing paradigm or dominant theories and lead to a significant transformation in the way the field is understood or studied. Paradigm shifts can have profound implications for the direction of research, the interpretation of data, and the development of new theories and frameworks within a particular discipline. These shifts often occur as a result of groundbreaking discoveries, technological advances, or shifts in societal values and priorities.
