Doesn't everyone on this Forum know people who are extraordinarily bright on some subjects or areas of life, and really 'stupid' in others?
Time and time again, I've seen this in people, including myself; long ago it became obvious that intelligence (as opposed to "IQ") is highly multidimensional.
Sure. Every Democrat member of MENSA.

Answer: Yes I.Q. is multi-dimensional; however, the point is each of the factors seems to correlate with a general factor called "g." If Dr. Gardner gave us his data (if it exists) we could do correlation coeficients and determine whether and how much these factors of his correlated with "g." Generally, almost all I.Q. tests (and there are a considerable number) all have performance or verbal factors which all correlate with "g" if they measure performance at all.
Think of "g" as something like heat. You can measure it. You can quantify it. But it is still hard to define. Heat does follow certain laws and "heat" can be found in anything we call "hot." Not a good analogy perhaps, but the only one I can come up with now.
The only reason to discuss these matters is that people keep making statements and actions which run contrary to nature. For example, some years ago it was discovered the State of California was giving I.Q. tests to children to determine if they needed special education and help. It turned out that 30% of the Black children needed this help. A federal judge looked at this and said it was "racism" and forbid the schools from giving Black children I.Q. tests. This was the law of the land, until recently when Black parents demanded some exceptions.
If you find a child with a learning disorder it is important to make the proper diagnosis and proceed. Generally, the less able the student the more it is going to cost in time and money to achieve an amelioration or solution to the problem. The hysteria on the left about I.Q., racial differences and genetics have actually impaired the ability of professionals to do a better job and politicians from directing sufficient and necessary resources to do that job.
