While it seems intuitively pretty clear that fairness involves an equal division of something
I’d say that’s wrong, and that humans believe fairness to be the appropriate division of something, with ‘appropriateness’ corresponding to a set of principles defining the relationship between effort, resources, and entitlement.
Sometimes equal division is seen as being fundamentally unfair. See the parable of the workers in the vineyard for a classic example.
