Some subjectivists and relativists need not agree to these statements from "measures" of subjectivism and relativism, raising questions about face validity. Can psychologists chat with philosophers before making scales like these?
#Subjectivism:
The truth does not exist
All subjective perceptions of a chain of events are equally true
#Relativism:
It is impossible to compare different cultures beliefs about reality in terms of "correctness"
