I am in the process of writing grant applications for dissertation research and part of my explanation for my need for continued funding is that I am interviewing a population that requires a high level of trust, acceptance, and TIME in order to obtain rich, complex, and honest interview data. Many of the people in my "sample" are political leaders - they have a well-practiced rhetoric and particular spin and it takes several interviews and meetings to even begin to get past the "party line" and to the more individualized narratives. I want to make this point as a justification for further time needed in the field. Does anyone have any methodology literature or case studies they could point to that might help solidify my argument?
