Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, and Jonathan Birch, Sentience in decapod crustaceans: A general framework and review of the evidence


The rigorous framework for research into potential pain in decapods was successful in allowing legislators in the United Kingdom to evaluate a complex scientific issue. However, it might produce problems for research. I discuss doubts about the usefulness of the eight criteria. Some have yet to receive any investigation and others do not allow much inference about pain. In addition, some existing studies are not covered in the framework. Most worrying, however, is the potential for stifling future research of novel areas that are excluded from the framework.
