 Let us return to the general picture of scalar need for informed consent, which depends on many variables and generates different requirements on different occasions. It also raises interesting practical questions. First, who should decide when fully informed consent is necessary (Joffe and Truog 2010, 361)? Might a crude, one-size-fits-all requirement of informed consent serve most practical purposes (Wertheimer 2014)? Perhaps a fair compromise is to use an “intervention ladder” that defines broad categories of intervention as more or less intrusive, then specifies broad categories of circumstance that require especially robust consent in some cases and only minimal consent in others (Nuffield Council on Bioethics 2007, 41–3)? What seems, in any event, to emerge is that the need for informed consent would be misrepresented as fundamentally a single constraint or threshold. In this area, at least, commonsense morality acknowledges that prescriptions’ strengths and characters vary, with multiple determinants.
