One comparison I am interested in is with an important baseline table from the 1972 American National Election Survey. That survey's table crossed the "are you an optimist or a pessimist?" question with the "do you think most people can be trusted?" question.
I am interested in this issue, because I think trusters, especially optimistic trusters, are the people most likely to undertake Tocquevillian projects of community improvement.
