Abstract: We examine some examples where the use of cardinal preferences solves problems that occur when ordinal preferences are used exclusively. Ordinal preferences are the first step toward ranking alternatives but they are not the last. In general we are interested in deriving a consistent ranking of alternatives which may then be used to construct a scale after a unit of measurement has been developed.
