>>11539836idk about this particular theory.
But I do agree that intelligence is multi-faceted and it is rare to find someone with a full spectrum high intelligence. People like to tout IQ as being an amazing thing, but in reality it only encapsulates a small portion of intelligence generally associated with test taking abilities. Even if someone scores obscenely high they might never actually do anything with their life because they don't understand people or hold the capacity to understand themselves.
Different types of intelligence can be cultivated better than others, some are more useful in daily life and some in specific circumstances.
