A recent article by British scientist and author Matt Ridley denies rats the capacity for empathy primarily on the flimsy basis that studies on ants show them helping a distressed fellow ant. As it seems “absurd” to attribute empathic suffering to a social insect, we should not stoop to crediting such feelings to rats either, according to Ridley, and the authors of a recent paper in Biology Letters.
For the record, I have great respect for ants, and I won’t jump to conclusions about their capacities. But why on earth would we use ants as a yardstick for the emotional capacities of rats—a species with a demonstrated capacity for laughter, pessimism, emotional fever, and metacognition (awareness of one’s own knowledge)?
