 Barry et al (2014) use empirical studies to support the 3rd category approach to safety net cases. They argue that empirical studies show that removing a barrier to harm (enabling) is treated as a distinct category, both morally and conceptually distinct from doing and allowing. Most philosophical work on the doing/allowing distinction seeks to reflect something that is claimed to be part of commonsense morality while noting that common intuitions about particular cases could be incorrect. Given this, there are interesting questions about how to respond to such empirical studies: does the fact that enabling is treated as a distinct category settle whether it is a distinct category for the purposes of the defender (or critic) of the doing/allowing distinction?
