The science of animal sentience and the politics of animal welfare should be kept separate

Although linked historically by Rowan et al., the scientific study of animal sentience and political campaigns to improve welfare should be kept separate, for at least two reasons. First, separation makes it clear that standards evidence acceptable ethical or decisions on can lower than those required a rigorously approach sentience. Second, helps avoid confirmatory bias in form giving undue weight results are line with pre-conceived ideas views.
