If we wanted to predict the political activity of the entire ENS community, such as in a census or pre-election poll, your concern would be valid. However, we do not aim to represent the entire community. Not only because of feasibility issues, but also because our preliminary research and data analysis show valuable possibilities for gaining insight about the segment we call “The Pioneers, The 1%”. We believe that representing this segment is an achievable goal.

They are more active in the community where we would recruit participants, and less motivated by financial incentives. In our private market research practice, we have seen genuine participation interest from individuals with net worths of $100k or more for less than $2 (we can provide examples of this in private).
