Pigs are among the most cognitively sophisticated animals raised for food. The scientific evidence for their intelligence has profound implications for how we evaluate and improve their welfare.
The cognitive sophistication of pigs places them in a morally significant category that their current welfare standards in most jurisdictions fail to reflect. An animal capable of learning video games, forming lasting friendships, and experiencing pessimistic emotional states in poor environments is clearly experiencing a rich inner life that standard intensive farming conditions dramatically impoverish. The gap between what pigs are capable of experiencing and what conventional production systems provide is one of the most significant ethical inconsistencies in modern food production. Enriched environments, social stability, and genuine behavioral complexity are achievable improvements that begin to address this gap.
