Research into the cognitive abilities of pigs, chickens, cows, and sheep has revealed sophisticated learning, social intelligence, and emotional complexity that demands a fundamental reassessment of how we treat these animals.
The emerging science of farm animal cognition fundamentally challenges the assumption that these animals have simple inner lives that don't warrant moral consideration. Animals that learn quickly, remember individuals, experience emotions, and anticipate future events have welfare interests that deserve serious ethical weight. The cognitive sophistication revealed by research demands a response from producers, policymakers, and consumers.
