Beyond Ranking: Exploring Relative Preferences in P/RRA

In this paper we argue in favour of moving beyond simple preference ranking when exploring preferences in PRA or RRA. The main reason for this is that ranking actually tells us little about preferences. This is often less than we think, because so many of us misinterpret ranking data. But even when interpreted correctly, ranking is not enough. Scoring systems are better, and some are described here, but we shall also introduce two new techniques which help to provide better information about preferences.
