Analysis of the social utility of a new safety standard in Section 1.1 used two dimensions, people and their goals. Chapters 3 and 4 introduced a third dimension, possible outcomes. I have not yet presented group utility analysis, in which the dimension of analysis is people; that is reserved for Chapter 6. But having presented intrinsic utility analysis and expected utility analysis, in which the dimensions of analysis are goals and possible outcomes, respectively, I may undertake a two dimensional analysis of an option's utility for a person.

A two-dimensional analysis expands a point in one dimension of analysis along the other dimension of analysis. In this chapter's two dimensional analysis, the expansion takes place at an outcome, a point in the dimension for expected utility analysis. A possible world serves as the outcome, and its utility equals its intrinsic utility. Hence an intrinsic utility analysis may decompress its utility along the dimension of goals.

The two-dimensional framework makes my decision space more versatile. Using it, intrinsic and expected utility analyses may conjointly dissect an option's utility. This chapter explores the analytic fruits of two-dimensionality. It uses intrinsic utilities to compute comprehensive utilities of options given uncertainty.

INTRINSIC AND EXPECTED UTILITY ANALYSES COMBINED

Chapter 1 outlined multidimensional utility analysis. It involves the conjoint application of two or more independent forms of utility analysis.
