In the current historical climate, a domain where quantifiable measurement is possible takes precedence over one where it does not. We believe that things that can be measured are real, and we ignore those that we don’t know how to measure. So people take intelligence very seriously, because the mental ability we call by that name can be measured by tests; whereas few bother about how sensitive, altruistic, or helpful someone is, because as yet there is no good way to measure such qualities.
