So, What is Democracy Anyway? | Peter Emerson | TEDxVienna

In many instances, a majority vote identifies not the will of the people, not even the will of the majority of them, but the will of those who wrote the question. Most political problems are complex; to reduce them to a win-or-lose binary vote, or even a series of such dichotomies, often turns what should be a discussion into an argument. Preferential voting in contrast can be win-win: indeed, a points system can identify that option which, if not the most popular, is at least the most generally acceptable.
