Decades of animal cognition research have demonstrated sophisticated capacities across many species. This evidence raises the question: what welfare obligations follow from cognitive sophistication?
The welfare implications of cognitive research are profound. If an animal can anticipate future suffering, plan, remember past harms, and experience social relationships — then deprivation, isolation, and painful procedures cause harms that extend beyond immediate physical experience. Welfare standards built solely on pain threshold underestimate the scope of animal suffering.
