  • Pros and cons of a framework for evaluating potential pain in decapods

    • Authors: Robert William Elwood Professor
      Abstract: 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.

  • A framework for evaluating evidence of pain in animals

    • Authors: Matilda Gibbons et al.
      Abstract: Crump et al. define eight criteria indicating sentience in animals, with a focus on pain. Here, we point out the risk of false negative or false positive diagnoses of pain. Criteria of different levels of inclusivity are useful for using the precautionary principle in animal welfare considerations, and for more formal scientific evidence of pain. We suggest tightening the criteria -- from more general evidence of sentience to pain alone -- because crucial evidence for animal welfare decisions might otherwise be missed for animals subjected to invasive and injurious procedures.

  • The dissonance between knowing animals are sentient beings yet eating them

    • Authors: Yana Bender et al.
      Abstract: Animal sentience is linked to the bigger picture of climate and health crises and “carnism” is a factor in the dissonance among (1) knowing animals are sentient, (2) caring about their feelings, and (3) not acting accordingly. We discuss our responsibility as researchers and as individual human beings.

  • Decapods as food, companions and research animals: Legal impact of
           ascribing sentience

    • Authors: Jonathan J. Cooper et al.
      Abstract: This commentary provides an overview of the practical implications of attributing sentience to protect decapods as food, companion and research animals in the UK context. Recognising their capacity to suffer has implications for humane slaughter in farming and fishing sectors. It should also place a greater duty of care on owners of captive decapods, considering their needs and avoiding unnecessary suffering. The recognition of decapod sentience should also have an impact on their protection as research animals, although research with a potential to cause suffering may be needed to better understand decapods’ capacity to suffer.

  • Motivated science: What humans gain from denying animal sentience

    • Authors: Uri Lifshin
      Abstract: Resistance to the idea that non-human animals are sentient resembles erstwhile resistance to the theory that the earth is not the centre of the universe, or that humans evolved from “apes”. All these notions are psychologically threatening. They can remind people of their own creatureliness and mortality and might make them feel guilty or uncertain about their way of life. An honest debate over animal sentience, welfare and rights should consider the human motivation to deprive animals of these things in the first place. I briefly review empirical evidence on the psychological function of denying animal minds.

  • Lack of imagination can bias our view of animal sentience

    • Authors: Brian Key et al.
      Abstract: How an animal reacts to a sensory stimulus is often used to assess whether that animal can experience feelings such as pain and pleasure. This behavioural path is typically complemented with reference to how a human would normally respond to and experience an analogous stimulus. Together, these approaches can lead to a “hard to imagine otherwise” argument for feelings. It is time to go beyond these qualitative assessments and to now determine whether a nervous system can execute the neural functions necessary for sentience.

  • Animals may be more reliably emotional than humans

    • Authors: Gerben A. van Kleef
      Abstract: Despite considerable advances in the study of animal sentience, reluctance to credit non-human animals with emotional capacities persists. I argue that this reluctance is untenable in light of (evolutionary) theory and empirical evidence. Humans may differ from animals in their ability to reflect on, reason about, and deliberately regulate their emotions. If anything, however, this implies animals’ emotional displays provide a more valid and reliable window into their internal states than do humans’, whose displays may be strategically altered. Any signs of pleasure or distress thus constitute direct readouts of animal wellbeing. It is time we start treating animals accordingly.

  • Extending the null hypothesis to invertebrate pain sentience

    • Authors: Eva Kakrada et al.
      Abstract: In 1985 Macphail proposed his Null Hypothesis that there were no qualitative differences in intelligence across vertebrate species. A recent review of the literature has found overwhelming support for his view. Studies also suggest that, with respect to cognition and the neural mechanisms that support it, the Null Hypothesis should be extended to invertebrates. We suggest, on the same premise, that the Null Hypothesis should be extended to pain sentience in invertebrates. Although few studies have been conducted, behavioural and neural evidence for pain sentience has been found in various representative invertebrate species.

  • The reality and prevalence of animal sentience

    • Authors: Antonio Damasio
      Abstract: Rowan et al use findings from neurobiology, clinical neurology, and general biology to argue for the extensive presence of sentience in animals, but they are wisely cautious concerning when in the phylogenetic scale that emergence occurred.

  • Decapod sentience: Promising framework and evidence

    • Authors: Jon Mallatt et al.
      Abstract: Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they have not yet been gathered. Future studies should explore how decapods are sentient with so few neurons in their nervous system (

  • Animal sentience in Indian culture: Colonial and post-colonial changes

    • Authors: Nanditha Krishna
      Abstract: The Indian tradition has respected animal sentience and non-injury toward all life. It is repeated consistently in Sanskrit literature and the later literature of the Jains and the Buddhists. Change came with the advent of Islamic rule followed by the British, who built slaughterhouses. The hunting of wildlife increased and several wild predator species were wiped out. The result was the series of legislations for animals which were initially proposed by the SPCAs and later by NGOs. In 1976, the Constitution of India was amended to make the protection of wildlife and compassion for living creatures a fundamental duty. However, in spite of the importance of the non-killing of animals, the meat industry for both domestic consumption and export has been growing. It is an ongoing struggle between activists, governments and the business class.

  • How much of a pain would a crustacean “common currency” really

    • Authors: Simon A. B. Brown
      Abstract: We should be suspicious of the idea that experiencing pain could enable animals to trade off different motivations in a common currency. It is not even clear that humans have a common motivational currency reflected in evaluative experience. Instead, pain may capture attention, inhibiting attention to competing motivations and needs, thereby making genuine trade-offs harder. Our criteria for pain in invertebrates should be part of a more subtle theory of the relationship between pain and decision-making.

  • Animal sentience science and policy

    • Authors: Andrew Crump
      Abstract: Animal sentience research cannot be divorced from its ethical and political implications. For example, discovering which animals are sentient is vital for deciding which require welfare protection. Two legal case-studies illustrate the importance of scientists in such debates: the UK Animal Welfare (Sentience) Act 2022 had input from animal sentience researchers, whereas the US Animal Welfare Act 1966 did not. The former defined sentient animals much more plausibly than the latter. I accordingly argue that sentience researchers should inform policy, and that this is achievable without sacrificing scientific integrity.

  • Sentience as part of emotional lives

    • Authors: Frans B. M. de Waal
      Abstract: It is high time to explore the sentience of invertebrate animals, but this topic cannot be discussed without also exploring their emotional lives, including positive emotions. Sentience probably evolved to allow the regulation of emotions by endowing them with feelings.

  • Sentience criteria to persuade the reasonable sceptic

    • Authors: Patrick Butlin
      Abstract: When presented with evidence that Crump et al.’s criteria are satisfied for the animals in some taxon, a sceptic could reasonably continue to suspend judgement about whether those animals are sentient. This is because the criteria refer to abilities which are associated with sentience in humans, but it is not clear that sentience is necessary for these abilities. The criteria could be strengthed by requiring evidence of a contrast in performance between cases in which information is carried by felt and unfelt states.

  • Unconscious humans, autonomous machines and the difficulty of knowing
           which animals are sentient

    • Authors: Marian Stamp Dawkins
      Abstract: The framework proposed by Crump et al. still leaves much doubt about whether invertebrates such as crabs are sentient. For example, many complex behaviours - even in humans - occur without sentience. Also, simple machines could easily meet all of Crump et al.’s eight proposed criteria for sentience. Acknowledging the limitations of what we currently know about sentience is important both for formulating legislation correctly and for advancing scientific understanding of this most puzzling of biological phenomena.

  • Sentience in decapods: an open question

    • Authors: Mark Briffa
      Abstract: Crump et al.’s framework is a powerful tool designed to assist decisions on the ethical treatment of decapod crustaceans. However, the question of whether decapods are sentient (i.e., whether they feel), remains open, perhaps indefinitely. More optimistically, we might design experiments that distinguish among different levels of awareness, sometimes viewed as components of sentience. We should strike a balance between assuming that all organisms are sentient and making unnecessary anatomical assumptions about sentience. Refining current experiments may provide concrete insights about awareness in Decapoda and other taxa.

  • Wild animal welfare

    • Authors: Clare Palmer et al.
      Abstract: Rowan et al’s article provides an overview of developments in the science of animal sentience and its links to animal welfare policy, especially regarding farm animals. But changing ideas of animal sentience and welfare are also important for managing wild and other free-living animals. We ask how the welfare of these animals differs from that of farmed animals, especially how the ability to make autonomous choices may matter. We suggest that more research into wild animal welfare is needed to make informed policy decisions, for example, about using animals in rewilding projects and choosing between policies of culling and fertility control.

  • Defining and assessing sentience

    • Authors: Barry O. Hughes
      Abstract: Precisely what is meant by the term sentience and how does it overlap with being conscious' We accept that animals have feelings but how do we know what they are and can we measure them' It is important that we clarify the terminology underlying these difficult concepts. Over the last 50 years a scientific discipline has developed to tackle these questions in a systematic way. We have to avoid thoughtless anthropomorphism yet we have to try to relate sentience in animals, as appropriate, to corresponding experiences in humans.

  • Unresolved issues of behavioral analysis in invertebrates

    • Authors: Charles I. Abramson et al.
      Abstract: Crump et al. (2022) provide a framework for determining the presence of sentience in organisms. Their target article is interesting and thought-provoking, but it does not consider the many unresolved issues related to behavioral analysis – especially when it concerns invertebrates. We feel that no real progress can be made until such fundamental issues as the need for a consistent definition of conditioning phenomena, the lack of a generally accepted behavioral taxonomy, and the use of cognitive terms to explain invertebrate behavior are examined critically.
