Pigs reconcile after fighting. That confirms their intelligence

“I like pigs,” Winston Churchill supposedly once said. “Dogs look up at us, cats look down on us, but pigs treat us as equals.” Whether Churchill’s contemporary George Orwell also liked pigs is less clear. But he, too, surely saw something in them that was lacking in other domestic beasts, for it was they who ended up running the show in his allegorical novel, “Animal Farm”. Pigs, then, are intelligent social creatures.

And, like all animals, they sometimes fight. A study just published in Animal Cognition by Ivan Norscia, a biological anthropologist at the University of Turin, in Italy, and his colleagues, looked at how a group of 104 domestic pigs went about resolving such incidents. In total, Dr Norscia and his team studied the details of 216 porcine conflicts over the course of six months.
