Cognitive ethology — the scientific study of animal minds — has transformed our understanding of animal mental complexity, with profound implications for how we think about animal welfare and moral status.
Cognitive ethology has shifted the scientific consensus from behaviourism — which dismissed animal minds as unknowable — to a nuanced understanding of diverse cognitive abilities across the animal kingdom. This shift has direct welfare implications: if animals have rich cognitive lives, their welfare needs extend beyond physical comfort to include cognitive stimulation, social complexity and positive emotional states. The discovery of cognitive complexity in species previously assumed simple — fish, octopuses, bees — expands our moral responsibility further than most welfare frameworks have yet caught up to. Welfare environments must be designed with cognitive needs in mind.
