In Western iconography, Justice is blindfolded and holds aloft a balance scale. The blindfold represents impartiality-because Justice cannot see the people before her, her decisions will not be prejudiced by their appearance. The scale represents the use of publicly accepted principles-all can see as Justice weighs the punishment to the crime. Several doubts about the correspondence between this ideal and the reality of how justice is administered in nations and other organizations surface when justice is considered in relation to cultural and ethnic differences. Most familiar, but not the emphasis of this chapter, is the objection that Justice wears no blindfold: Justice administrators not only see but take into account ethnicity and culture. 1 This chapter focuses on an objection to the notion of universally accepted principles that is signified by Justice's scale. There is increasing doubt that principles of justice, like the principles of physics that govern a scale, are recognized by people everywhere. That is, some claim that what we see when we see justice depends on the lens of one's culture or ethnicity. Such differences in perceptions of justice create a deep difficulty for a society or organization that aspires to provide ''justice for all,'' because even if partiality is purged from the system it will be impossible to deliver decisions that all of the people perceive as just.In a long tradition, philosophers from Aristotle to Rawls have studied objective principles of justice. That is, they have endeavored to identify principles of social conduct that are just according to external logical standards. In a much shorter tradition, social psychologists have studied subjective principles of justice. That is, psychologists have addressed the question of what principles determine people's perception of a social situation as just or unjust. This work has produced complex models of the psychological processes that lead one to perceive fairness in a particular way of distributing scarce resources, or of making a socially important decision,
