Research on animal cognition continues to reveal capabilities previously thought uniquely human. These findings have direct implications for how we understand animal welfare needs and moral obligations.
Each new finding in animal cognition science has welfare implications because cognitive capacity shapes the nature of subjective experience. An animal capable of episodic memory can remember past suffering and anticipate future negative events; an animal with theory of mind can experience social isolation with awareness of what it is missing. The accumulation of cognitive science findings has created an increasingly compelling case that our conventional distinctions between animals deserving moral consideration and those that do not are scientifically unjustified. The challenge for welfare is translating this expanding scientific understanding into practical obligations: if crows can plan for the future, what do we owe them? If fish can count and use tools, what does that mean for their welfare in fishing and aquaculture?
