Author reflexivity is increasingly common practice in publication, though certainly not universal. Especially significant in conducting qualitative research, author reflexivity acknowledges that we all bring our own interpretations and biases to our work, regardless of efforts made to remain detached from the research in order to engage in "objective" analysis. Indeed, the very essence of the debate between positivists and interpretivists is whether or not knowledge is measurable and neutral or constructed and dependent upon human experience. Regardless of the research paradigm with which your project aligns, consideration of author reflexivity should be a part of your QES project.
Potential conflicts of interest must be disclosed and reconciled among the research team. Including a statement about the authors position, social location, and experience with the subject matter at hand is an important step toward transparency and acknowledgment of implicit - and occasionally explicit - bias. Disclosure of these matters does not render your study any less valuable, rather it allows the reader more insight into how conclusions were drawn.
