  • The reason this corvid study is different from intuitively knowing that 10-10=no berries is where this 0/empty set is represented on the numberline.

    Considering 0 as a number vs the empty set are two different concepts. It’s the difference between having a bank account with $0, vs having no bank account. They don’t close your account when you have $0, so it’s still an amount of money.

    Crows considering 0 on the numberline, and differently from the empty set shows they have a more abstract concept of numbers than we thought.

    Idk who authored this study, seems like a very specific kind of person who is both into number theory and neural pathways of birds to design.
