It is also important to note that this approach to research is used to explore life experience from those belonging to all other minority groups. Distinguished British sociologist, feminist, and writer, Ann Oakley has written numerous academic works focusing on the lives and roles of women in society. Oakley is a well-known pioneer in the unstructured interview research approach directed towards qualitative research that challenges existing power imbalances within the relationships of the interviewer and the interviewee. Oakley sees both issues as interlinked or, as she puts it "no intimacy without reciprocity". In 1974, Oakley interviewed women twice before the birth of their children and then twice afterwards. Each woman was interviewed for around nine hours on average. The women also asked her questions during the interviews and Oakley responded as openly and honestly as she wished for them to respond. Oakley wanted the respondents to be collaborators in her research rather than just interviewees causing the women to become increasingly interested in the research and contacting her with any information they thought important after the interviews. Oakley as well used the unstructured interview approach to study women's experiences of both house work and maternity care. Oakley interviewed 40 women about how much housework they did and how they and their partners organised domestic work. Both unstructured interview studies "were aimed at raising awareness of women's experiences and of promoting policy changes - for example, Oakley called for domestic work to be recognized as 'work' and to be given an appropriate status in relation to paid employment". These are prime examples of the advantages of rapport and the depth of information even beyond the interview using the unstructured interview research approach.
