The better question would have been “how do people identify objects which behave like integers?”.
The same way we identify objects which satisfy any other predicate? We determine whether or not something is a cat by comparing it to our knowledge of what cats are like. We determine whether or not something is dangerous by comparing it to our knowledge of what dangerous things are like.
Why do you ask this question specifically of the integers? Is there something special about them?
