Fragmentation in research refers to the division of a topic or field of study into smaller, more specialized subtopics or areas of focus. This can occur due to the growth of knowledge, the development of new methodologies or technologies, or the emergence of new research questions. Fragmentation can lead to a more nuanced understanding of specific aspects of a topic, but it can also make it challenging to integrate findings across different subfields or to identify overarching patterns or trends. Researchers may need to collaborate across disciplines or engage in interdisciplinary research to address the complexities and challenges posed by fragmentation in their field.
