The Edge of Sentience: risk and precaution in humans, other animals, and AI
LSE: Public lectures and events
Deep Dive
What is the main focus of Jonathan Birch's book 'The Edge of Sentience'?
The book focuses on developing a precautionary framework to make ethically sound, evidence-based decisions in cases of uncertainty about sentience in humans, other animals, and AI. It addresses questions like whether octopuses, crabs, or AI can feel pain or pleasure and how to manage these risks responsibly.
Why does Jonathan Birch prefer the term 'sentience' over 'consciousness'?
Birch prefers 'sentience' because it captures the capacity to have feelings that feel good or bad, such as pain, pleasure, boredom, or joy. 'Consciousness' can refer to more complex cognitive overlays, while 'sentience' focuses on the immediate raw experiences, which are more relevant to ethical considerations.
What evidence supports the claim that octopuses are sentient?
Experiments like the conditioned place avoidance test show octopuses exhibit behaviors similar to mammals in response to pain. For example, octopuses avoid chambers where they experienced pain and prefer chambers where they received pain relief, indicating a realistic possibility of sentience.
What are the ethical concerns surrounding octopus farming?
Octopuses are solitary and aggressive in close confinement, leading to injuries and stress in farming conditions. Intensive farming raises significant welfare concerns, and Birch advocates for preemptive bans on octopus farming and imports of farmed octopus to prevent unnecessary suffering.
How does Jonathan Birch propose addressing uncertainty about sentience in AI?
Birch suggests treating AI systems as sentience candidates if there is a realistic possibility they could feel pain or pleasure. He advocates for a precautionary principle, looking for computational markers or behavioral experiments that could indicate sentience, rather than dismissing the possibility outright.
What is the significance of the Animal Welfare Sentience Act of 2022?
The Act extended protections to include cephalopod mollusks and decapod crustaceans, such as octopuses, crabs, and lobsters, recognizing them as sentient beings. This change was influenced by Birch's research and aims to improve their welfare in practices like farming and slaughter.
What role do citizens' assemblies play in Birch's framework for managing sentience risks?
Citizens' assemblies are proposed as democratic mechanisms to debate and decide on proportionate responses to sentience risks. They allow the public to weigh in on ethical and policy decisions, ensuring that expert assessments of risks are balanced with public values and preferences.
Why does Birch argue against overconfidence in denying sentience in certain cases?
Overconfidence in denying sentience, such as in the case of unresponsive brain injury patients or invertebrates, can lead to neglect and suffering. Birch highlights historical examples, like surgery on newborns without anesthesia, to show the dangers of assuming sentience is absent without evidence.
