 In any case, some philosophers may wonder about the philosophical relevance of this experimental research. One response is that it could affect criteria of success in meta-ethics. For example, it is sometimes suggested that most people are moral objectivists rather than moral relativists, and that a meta-ethical position such as moral realism gains credibility because it is in accord with folk morality so understood (see Smith 1991). The studies just cited and others appear to challenge the factual premise of this meta-ethical criterion (see Sarkissian 2017), and it has been argued that the best interpretation of the empirical data is that many people accept a form of relativism (see Beebe Forthcoming). Another response is that some of the complexity revealed in these studies might lead philosophers to consider more seriously the philosophical viability of a pluralist or mixed meta-ethical position according to which, for instance, moral objectivism is correct in some respects, but MMR is correct in other respects (in this connection, see Gill 2008 and Sinnott-Armstrong 2009). There is more on this issue in  section 7.  In any case, there is increasing recognition of the importance of interpreting the significance of the experimental evidence for meta-ethics with care (see Bush and Moss 2020, Hopster 2019 and Pölzler and Wright 2020).
