Pigs are among the most cognitively sophisticated farm animals — their intelligence has direct implications for the welfare harms caused by barren, intensive systems.
The cognitive sophistication of pigs directly amplifies the welfare cost of their intensive confinement. An intelligent, curious, socially complex animal confined in a barren concrete pen with nothing to do experiences a qualitatively different and more severe form of deprivation than a less cognitively complex animal in the same conditions. Pigs explore, investigate, solve problems, and form complex social relationships. Preventing all of these behaviors does not just frustrate individual motivations — it deprives animals capable of rich inner experiences of nearly all meaningful stimulation. This is among the strongest arguments for prioritizing pig welfare reform.
