I think PG is mainly talking about how the ratio of certain personality elements and basic strengths might contribute to a higher perceived "intelligence". i.e. Someone with a high EQ (Emotional Quotient) relative to their spatial reasoning might seem more intelligent than the person with lower EQ and higher spatial reasoning, while someone with an equally high EQ and spatial reasoning might develop some sort of personality disorder. (Hopefully not, but just an example) This could probably be extrapolated into ratios between language skills, creativity, ability to grasp abstraction, memory, etc. etc.
