Research into pig cognition demonstrates problem-solving, memory, and emotional intelligence that challenge assumptions about their capacity for suffering and positive experience relevant to welfare standards.
Evidence of pig cognitive complexity strengthens the welfare case for high standards of care. Animals with greater cognitive capacity may experience both suffering and positive states more intensely than simpler animals. The ability of pigs to form complex social relationships, experience boredom and frustration, show empathic responses, and potentially have self-awareness creates obligations beyond basic physical care. The frustration of intelligent, social animals in barren, restrictive environments is qualitatively different from physical deprivation alone. Providing environments that allow positive cognitive engagement, social bonding, and behavioral complexity is a welfare imperative grounded in the scientific understanding of pig cognition.
