Zones Of Precaution, Jonathan Birch
Zones Of Precaution, Jonathan Birch
Animal Sentience
My commentary focusses on Mikhalevich & Powell’s criticisms of the Animal Sentience Precautionary Principle. I emphasize the pragmatic nature of my rationale for proposing that, rather than extending the scope of animal welfare protection on a species-by-species basis, we should be willing to protect entire Linnaean orders on the basis of evidence from a single species.

Animal Sentience
I respond to commentaries by Elwood and Seth & Dienes and to a recent critique by Diggles, discussing the link between avoidance learning and sentience, the relevance of the clash between frequentist and Bayesian statistics, the risks to decapod welfare in aquaculture, and the broader concerns one may have about a “precautionary” approach to protecting invertebrates.
Animal Pain And The Social Role Of Science, Leslie Irvine
Animal Pain And The Social Role Of Science, Leslie Irvine
Animal Sentience
Assuming that all animals are sentient would mean ending their use in most scientific research. This does not necessarily imply an unscientific or anti-scientific stance. Examining the social role of science reveals its considerable investment in preserving the status quo, including the continued use of animal subjects. From this perspective, the use of animal subjects is a custom that science could move beyond, rather than a methodological requirement that it must defend.

A Preliminary Investigation Into The Welfare Of Lobsters In The Uk, Gemma Carder
Animal Sentience
The welfare of invertebrates is overlooked and their needs are not understood. It is assumed that they do not experience pain and suffering. Studies on decapod crustaceans challenge this assumption. Research has focused on distinguishing between nociception (the ability to detect a harmful stimulus and to react to it reflexively) and pain (an aversive feeling or emotional experience). Findings indicate that decapod crustaceans can experience pain, which supports a case for protecting their welfare. I have investigated the current husbandry conditions of a globally consumed decapod crustacean, the lobster, as housed in tanks inside food outlets in the UK. Housing …
Cautions About Precautions, Jay R. Stauffer Jr.
Cautions About Precautions, Jay R. Stauffer Jr.
Animal Sentience
Assuming an animal to be sentient in the absence of conclusive evidence to the contrary is an extreme position, hence it should not and could not be the default assumption. Birch explains how the precautionary principle may be used to substantiate decisions to give the animal the benefit of doubt. Although I am reluctant to accept all of his points, Birch has provided an excellent argument for the use of the precautionary principle for the detection of animal sentience. I agree that more research is needed to refine and understand this relationship.
A Risk Assessment And Phylogenetic Approach, Culum Brown
A Risk Assessment And Phylogenetic Approach, Culum Brown
Animal Sentience
The precautionary principal is often invoked when talking about the evidence of sentience in animals, largely because we can never be certain what any animal is thinking or feeling. Birch (2017) offers a preliminary framework for the use of the precautionary principal for animal sentience combining an epistemic rule with a decision rule. I extend this framework by adding an evolutionary phylogentic approach which spreads the burden of proof across broad taxonomic groups and a risk assessment component which magnifies the likely impact by the number of animals involved.
