28	Hunt M, Carnevale F. Moral experience: a framework for bioethics research. Journal of medical ethics 2011, 37(11):658–662.	Moral experience hermeneutics (name assigned by reviewer)	Methodology designed to understand the moral practice of a population and therefore does not fully explore how to generate normative conclusions.

Medicine, Health Care and Philosophy 2012,15(2):129–139.	Ethics of public understanding	Proposed tool for making decisions that are congruent with the views of those affected.

31	Dunn M, Sheehan M, Parker M, Hope T. Toward methodological innovation in empirical ethics research. Cambridge Quarterly of Healthcare Ethics 2012, 21(4):466–480.	Grounded moral analysis	A constructivist account that aims for full integration of empirical analysis and normative analysis to develop normative claims that are justified and that have real-world purchase. Methodology centres around an iterative process of empirical research and theory being used to influence and change each other until a normative outcome is shaped by participants
		Moral conversation	A dialogical approach coming from the same theoretical standpoint as above. Intended to bring about focussed engagement and reflection within practice by forming a dialogue between stakeholders
		Moral participation	Again, from the same theoretical standpoint as above. The researcher actively experiences a situation and then undergoes a process of critical reflection which must stand up to ethical reasoning
32	Rehmann-Sutter C, Porz R, Leach Scully J. How to Relate the Empirical to the Normative. Cambridge Quarterly of Healthcare Ethics 2012, 21(4):436–447.	Phenomenological Hermeneutics	The researcher produces ethical arguments which, on phenomenological foundations, the data provides the conditions to evaluate. Involves hermeneutic ‘circles’- including whether the future ‘reader’ of any conclusion made will consider their findings to have any normative authority
33	Ives J. A method of reflexive balancing in a pragmatic, interdisciplinary and reflexive bioethics. Bioethics 2014. 28(6):302–312.	Reflexive Balancing	Although utilising the concept of coherence this methodology is distinct from reflective equilibrium in that it gives initial weighting to certain ‘boundary’ principles with which coherence is sought but which must then justify their own inclusion. This is likened to a ‘null hypothesis’ which must be proven or disproven. An explicitly pragmatic process, relying on a naturalistic ethics that focuses on achieving a defensible compromise in genuinely dilemmatic situations.
