This is really interesting because it forces me to think about what it means to be "American" based on what I know (or don't know) about two countries. Occasionally, I know enough about each country to make an informed decision, but often, all I have to go with are the locations as given by the webpage, and my own personal familiarity as to whether or not I've heard the name. Statistically, this should average out among the number of participants, but I wonder what strategies others use to answer the question?
Thanks, I'm looking forward to seeing what the results look like, once I get enough people to submit.
