Scientific research has revealed that pigs possess cognitive abilities rivaling those of dogs and primates — with profound implications for how billions of pigs are treated.
Pig intelligence research has comprehensively dismantled the assumption that pigs are low-cognitive animals unsuited to welfare consideration beyond basic physical needs. The evidence reveals animals capable of self-recognition, symbolic reasoning, emotional contagion, and complex social understanding — all of which carry welfare implications. A pig who recognizes itself in a mirror, who catches the emotional state of a distressed companion, who knows what it does and does not know, is an animal whose psychological experiences are morally significant in ways that the industry has largely failed to acknowledge. The cognitive evidence for pig welfare standards that prevent frustration, provide enrichment, and allow positive social experiences is overwhelming.
