Is Our “Number Sense” Biology, Culture — or Something Else?

It’s a surprisingly controversial question with a — perhaps unsettling — answer

British science writer Philip Ball, author of How to Grow a Human, offers an even-handed account of a controversy on the origin of our ability to understand numbers (numeracy). Numeracy is the beginning of mathematics, the most abstract of all human pursuits. It isn’t possible to get very far in mathematics without some ability to abstract. Ball cites as an example the difference between 152 and 153. Many life forms, competing for a pile of food items, can distinguish between 2 and 3. But distinguishing between 152 and 153 clearly requires abstraction. It’s the same principle as the chiliagon, a geometric figure like a triangle except that it has 1000 sides. A triangle can be envisioned concretely. A chiliagon can…

In What Ways Are Dogs Intelligent?

There is no human counterpart to some types of dog intelligence

At Gizmodo recently, George Dvorsky adopted the useful, though somewhat unusual, strategy of determining dog intelligence by focusing on what dogs can’t do. He starts with the premise, as put by University of Exeter psychology professor (and dog expert) Stephen Lea, who says that domestication “has radically altered the intelligence of dogs.” Not so much raised or lowered it as changed its nature from the type of intelligence we would expect from a wolf: “Dogs are very good at what they’re bred to do — they’re excellent at doing those things, and in some cases even better than other species we think are intelligent, such as chimps and bonobos,” Zachary Silver, a PhD student from the Comparative Cognitive Lab at…
