That touches on the issue I had with the article as well.
> "But psychometric studies, which seek to measure the nature of intelligence, paint a different picture. Millions of observations have shown that essentially all “primitive” cognitive abilities—short and long term memory, the use of language, the use of quantities and numbers, the visualization of geometric relationships, pattern recognition, and so on—are positively correlated."
Whilst it might have been "proven" in the lab, that's not what is apparent with day to day experiences. If we split 'intelligence' into 'academic intelligence' and 'emotional intelligence', it's rare to find someone who excels with both. It's not just a matter of capacity, our abilities are a reflection of what we devote our energy to.
To explain why it's important to make the distinction between different types of intelligence... to put it simply, academic intelligence makes a difference in abstract thinking, developing new ideas and refining existing ones. However, emotional intelligence guides us on how best to spend our time. Emotional intelligence is a close relative to wisdom. We need it to guide us. If not, we'll end up doing things because we can, rather than whether we should, and with the power of super-intelligence that's something we'll need more than ever.
