 The second approach to rejecting DMR focuses on the interpretation of the empirical evidence that purportedly supports this thesis. Some objections point to obstacles that face any attempt to understand human cultures empirically. For example, it may be said that the supposed evidence is incomplete or inaccurate because the observers are biased. In support of this, it may be claimed that anthropologists often have had preconceptions rooted in disciplinary paradigms or political ideologies that have led them to misrepresent or misinterpret the empirical data. Or it may be said that even the most objective observers would have difficulty accurately understanding a society’s actual moral values on account of phenomena such as self-deception and weakness of will. These concerns point to substantial issues in the methodology of the social sciences. However, even if they were valid, they would only cast doubt on whether DMR had been established: They would not necessarily give us reason to think it is false. Of course, this would be an important objection to someone who claims DMR is established or relies on DMR to argue for MMR.
