Consider the following statement for the role that ethics plays in both normative and positive economics. "Ethics is the study of morals standards and how it affects conduct and I believe it is more present in normative economics than in positive economics. There are no value judgments in positive economics, though the latter is measurable." Others have made similar remarks as well.
Can facts (or data) be interpreted in a way that may drive a particular policy? If so, can two groups using the same data interpret the data differently to generate distinctly different policies that may serve to further their own agenda?
Is this where ethics would come into play with positive economics? How do we (or can we) ensure that those interpreting the data do so in a way that would be considered ethical?
