I have an idea that I have developed after extensive literature review, I am quite sure I have formed an interesting hypothesis, although I am not completely sure this hypothesis is testable.
I would like to contact the expert in the field which I think should have most of the data I need and has probably done part of the analysis but has not looked at this data through the perspective I am interested in. I do not have any common collaborators with this person.
I am afraid that if I contact this person and explain my idea he might think that I am not needed to complete this research because I am not offering data or any particular methodology, and I would only be able to do only a small part of the data analysis. Basically I am not offering much aside from the idea and writing the article, thus my concern for being excluded by a potential article.
Due to time constraints I would not be able to do this on my own so I do not have many alternatives, how should I proceed?
