Surely we've all observed people that just don't care about something we would find interesting - that is real incuriosity. It's the same with my hunger analogy: someone could be hungry but not motivated enough to go and get food (but presumably not that hungry), while another person is genuinely not hungry at all, but the observable effect is the same. The reality is that emotions are subjective and we have no way to compare our experiences directly with others, but it's ridiculous to assert that they don't exist.
Agreed that this is all word games. Hopefully any good research would start by defining their terminology.
