I am not saying that there is a specific definition of intelligence that is good. I am saying that IQ as intelligence is not good. I wouldn't have a problem if people did use the terms "intelligence" and "IQ" so interchangeably. If the linked article talked only about IQ, then I would have no problem, but the article specifically talks about intelligence, and then uses studies on IQ to try to makes points about intelligence.
By the way, if you are looking for a better theory of intelligence (which is beside my point), then you should look at Cattell-Horn-Carroll Theory (http://en.wikipedia.org/wiki/Cattell-Horn-Carroll_theory) as an example.
Other than it correlates with all sorts of positive life factors, you mean? Like health, earning power and lack of a criminal record?
Nobody is saying that IQ is intelligence, including the author of the article. But it's a fairly large component of it.
