ABSTRACT
This chapter explores the justice evaluation is the outcome of a process in which the observer compares the actual reward to the just reward a process captured in the justice evaluation function. The actual reward is sometimes called the perceived-actual reward, because the observer's information about the rewardee's actual reward may be imperfect. The protocols for measuring the actual reward and the just reward for fictitious others rely on the factorial survey method pioneered by Peter H. Rossi. This chapter develops several research designs for measuring and estimating the trio of fundamental justice quantities and the associated fundamental justice functions. The International Social Justice Project (ISJP) has asked respondents in its fieldings of 1991, 1996, 2000, and 2006 to provide the actual reward and the just reward for two of the occupations studied in the ISSP. The two occupations are 'unskilled worker in a factory' and 'chairman of a large national corporation'.
