Weighting is certainly a difficult exercise. Even for engineers where the problems are more concrete, it often relies on building some sort of shared vision that is used to infer a future prediction. In fact most of the disagreements I see is when two engineers have a different view of the future. For sure, both quantitative and qualitative approaches are necessary to build a proper model. Anyways, my point was that by looking at every argument by first placing it on a left vs right scale removes the interesting nuances that could be discussed. I don't know that the engineering approach is necessarily the best tool to solve social inequalities as this is not my topic at all.
