The assumption that researchers are highly familiar with the subject of their investigations has not been much debated. Many years of secondary and tertiary education, as well as continuous engagement with new developments in their respective fields, form a basis for accumulated expert knowledge. Yet there are disciplines in which certain skills can only be acquired by extensive training outside the academic sphere. In particular, areas involving precise control of the body such as sports, dance or music performance require sustained physical training before individuals acquire expert-level knowledge (Ericsson 1996). In this regard, these disciplines differ from other academic fields, and it can be asked whether a certain level of skill and familiarity is necessary or at least beneficial for carrying out research in these areas.
