I think many people confuse IQ test for raw intelligence or mental capacity. They are not the same thing. There is, even in the best-designed IQ test a considerable amount of cultural knowledge and LEARNED problem-solving skills required for a high score.
What most IQ test measure is a combination of raw intelligence, problem-solving and cultural knowledge. This makes them difficult to apply to people that are not culturally similar. A person that has never been exposed to cultural items could not tell you what those items are regardless of how smart they are.
That is why IQ score typically rise with educational level. This has been shown by giving IQ test to students as they enter university. Their IQ - the same student - increases with each degree they achieve. If a student enters a university with an IQ of 100 they will typically graduate with an IQ of 115. If that same student then pursues and obtains an MA or MS their IQ has risen by another 5 points. Getting a Ph.D. raises the IQ still further. Why is this so? Because part of the education process is learning test-taking skills. In effect becoming educated allows you figure out things. (Or used to. I am not so sure this is as true as it once was)It isn’t that people with Ph.D.’s all started out as geniuses, they learned how to become a genius through acquiring problem-solving skills and developing mental discipline. Of course, there are exceptions to this rule.
(Note some test are better at screening for this than others and I am making a blanket statement. Please do not nit-pick. What I have written is generally accepted to be true.)
Thus, the charts in the Bell-curve show as much a lack of acculturalization and coping skills as they do low intelligence. The result, however; is the same. People that score lower on the test are going to, generally speaking, have less opportunity and fewer advantages in society. It doesn’t matter if they are just stupid or do not have the proper set of social and problem-solving skills. The solution is not to ignore the results or make arguments about them being kind, good, moral, or “differently intelligent” but to figure out how to maximize the acculturalization process among the less intelligent groups.
The poor, the less intelligent and the poorly acculturated can be fine, moral and polite people but they still have a problem with their IQ. Rather than simply giving them welfare or making AND ACCEPTING excuses for this we should help them raise their IQ.
A person without “moral intelligence” is not awfully bright to me. Look at somebody like Tony Podesta - rich, successful, corrupt and with truly execrable taste in art. Yet, Murray might consider him loaded with cognitive intelligence.

Cognitive intelligence is essentially how fast does one process and at what level of abstraction.
That is it. One can be an amoral slob but have an IQ in the 180s.
What you call moral intelligence is part of the sphere of my work on Emotional Intelligence which is self knowledge, emotional self management, understanding of others, management of relationships, empathy, passion, morality ethics, and joy.
Increasingly the IQ is the foundation for success in our culture and in many cases supersedes success in other spheres. This has been really emphasized in the tech industry.
