In broad terms of course emotional intelligence is very useful when interacting with other humans.

to pick at the 1-2% numbers a bit the impact of IQ depends on the individual; physical size/height is only profoundly important for the success of certain people - athletes primarily. however, both also have correlation with success. I'm sure the paper was more careful than this article.

IQ is often used as a proxy for intelligence, when in fact it's just a set of standard metrics that nobody thinks is that good beyond a certain point - after all the term comes from early attempts to quantify developmental delay. Leaving that aside for a moment.
