Locating researcher positionality
It is not a given that a researcher will explicitly locate themselves in relation to their research subject. It is an increasingly common practice, but we can't take for granted that it will always be present. In fact, I found it quite challenging to locate the examples below.
A good place to look for this type of information is within the introduction, or prior to the methodology section of a research study. If it is a book that you are reading, the preface or author introduction is a good place to look.
Here's an example of an author explicitly naming their position in relation to their research (see Qualitative Approach section).
And here is an example of a very cursory mention of author positionality.
