Chapter Fourteen. The Informational Basis of Social Choiceprotect Any procedure of social choice makes use of some types of information and ignores others. For example the method of majority decision concentrates on peoples votes but pays no direct attention to say their social standings or their prosperity or penury or even the intensities of their preferences. The differences between distinct procedures lie to a substantial extent on the kind of information that each procedure uses and what it has to ignore. The informational bases of the different social choice procedures tell us a great deal about how they respectively work and what they can or cannot achieve.
