Scientific research has revealed remarkable cognitive abilities in pigs, with welfare implications that challenge common assumptions about the animals we farm for food.
The scientific evidence for pig intelligence creates a profound ethical dissonance with intensive pig production practices. Animals with cognitive abilities on par with companion species we carefully protect are routinely kept in barren, highly restrictive environments that deny all meaningful behavioral expression. The welfare case for enrichment, social stability, and space is not just about preventing physical suffering but about enabling cognitive engagement appropriate to the animals' intelligence. Knowing that pigs can solve problems, form bonds, and show emotional responses like optimism or pessimism makes the barren battery-style environment of much intensive pig production a clear welfare failure.
