The importance of EQ is interesting especially because it is underestimated. Many tend to underestimate EQ because it goes into the category of soft values and also is more hard to measure than IQ.
Again it comes down to the question of if the mathematicians are superior to the ones coming with a background of social sciences etc.

But if you look at countries where there also is a focus on EQ then you will see that they are doing well. They are complete because they understood that in order to have a complete society you need to benefit from all sort of intelligence, which means both EQ and IQ.
In Scandinavia EQ is considered important, and these countries are after all doing quite well.
