Biographical research is a qualitative research approach that takes individual lives or life histories as its main focus of interest. It seeks to understand the social world through the detailed examination of personal experiences and the stories people tell about their lives. This type of research often involves in-depth interviews, analysis of personal documents (such as letters or diaries), and sometimes ethnographic observations to gain a rich and holistic understanding of the individual's life within their social context. Biographical research can provide valuable insights into social processes, cultural norms, and the ways individuals shape and are shaped by their social environments. It is used in various social science disciplines, including sociology, psychology, and anthropology, to explore topics such as identity formation, social change, and the impact of historical events on personal lives.
