If it’s really caring as such that we care about, this seems like an easy question. People tend to care more about people when they know personal details about the person. We would therefore expect accurate knowledge to show at least some correlation with caring, unless fear or deliberately misleading knowledge came into play. (And fear should matter less under CEV, if that rule works at all.)
So we should ask about the correlation?
