analytic models are capable of taking into account voter uncertainty, ignorance and incompetence. We shall also discuss how uncertainty pertains to electoral outcomes. Given voter opinions, there is often a wide variation in the possible electoral outcomes. This could be called procedure-dependence of outcomes. Its existence shows that uncertainty is not something that can characterize only future events. It can pertain to past ones as well. This work is part of the Democracy and Constitution Project of Center for Business and Policy Studies (SNS). The idea of writing a book on the performance of voting procedures under uncertain cir­ cumstances came up in my correspondence with Dr. Per Molander of SNS a few years ago.
