Not meant as an attack on the parent comment but I've been interested in the concept of judging things by inputs versus outputs. I see aspects of this in many controversial subjects; particularly homelessness. Different groups of people seem to focus on one side and ignore the other side of the equation when making arguments. These groups just end up talking past each other then and don't make progress towards a consensus.

I'm curious what kind of research (or keywords to search for) there is around this topic. Is it just a morality thing or does it go beyond that?
