9538 Assessment
Research Question The research area is clear, but the research question is vague.  Is not clear what "find out if the possible salience of .. racial/ethnic stereotypes in mainstream American media is associated with racial preferences in online dating" means.  Greater salience produces more racialized choices?  The pattern of racial dating choices reflects media stereotypes if salient?  
Relevant Literature The general discussion of literature is okay, but a bit meandering.  A well-defined research question should guide the literature review, which, above all else, reviews the existing work regarding the research question.
Causal Interpretations  
Data  It is unclear how the data described can be used to address the research question, at least as far as that question can be inferred.  We have no way of knowing what media the people in the dating data use, so we cannot relate their exposure to their dating preferences.   What the proposal means when talking about combining the data is obscure.
Research Value The general value of such information - if the research could succeed - is largely self-evident; the central question concerns whether this proposed study will provide any new knowledge.
Timetable Vague.
   
Priorities for Developing a Full Draft This project needs a clearer and more precise research question, one that can be sensibly related to prior research, and for which you can identify data that will really allow addressing the question.
