Research on pig cognition has revealed remarkable intellectual abilities that challenge assumptions about pig awareness and dramatically strengthen the moral case for better farm welfare standards.
Pig cognition research creates a compelling moral case for treating pigs' welfare with far greater seriousness than commercial livestock standards have historically demanded. Cognitive bias research — showing pessimistic bias in poor welfare conditions and optimistic bias in enriched environments — provides direct evidence that pigs' welfare conditions affect their emotional experiences in meaningful ways. Empathy-like responses demonstrate social emotional processing. Combined with tool use, problem-solving ability, and social complexity, the evidence portrait of pig intelligence rivals many species granted far greater moral consideration. The gap between what we know about pig cognition and how the majority of pigs are treated in intensive farming systems is among the most ethically troubling in contemporary animal welfare.
