Emotional Intelligence versus IQ
I think we can link EQ with wisdom and IQ with knowledge. One can be knowledgeable with others knowledge but one cannot be wise with others wisdom.
That effectively leaves
EQ to the genes and
IQ to the learning after birth. EQ is what you got through your genes from your forefathers-innate & deep features.
That proves why some people with limited education will rise to higher levels. Naturally that is due to EQ.
A person with a good EQ can survive without any IQ. But a person with good IQ and no EQ cannot survive in this universe.
Any leader, if we observe, will have more EQ than IQ.
