What is the purpose of literature reviews in research?

The purpose of literature reviews in research is to analyze existing research and identify gaps in the literature. By systematically reviewing previous studies, researchers can understand what has already been explored in their field, the conclusions drawn from those studies, and any limitations or inconsistencies present in the existing literature. This comprehensive understanding allows researchers to pinpoint areas that require further investigation, thereby supporting the development of their own research questions and hypotheses.

The analysis of existing research helps to ensure that new studies build on established knowledge and contribute meaningfully to the discipline. Furthermore, literature reviews provide context for the researcher’s work, demonstrating how their research fits into the broader academic conversation.

In contrast, summarizing personal experiences of researchers does not contribute to the academic rigor and objectivity valued in research. Gathering opinions from the general public may provide insights for certain research topics, but it lacks the systematic approach of a literature review focused on prior scholarly work. Lastly, creating new hypotheses without any background information undermines the foundation of scientific inquiry, which relies on existing knowledge to inform and shape new research directions.
