Intelligence is a multidimensional thing that is measurable in terms of actual performance. For example my cats and dogs have a higher level of social intelligence and conscientiousness than my high functioning adopted human child with Asperger’s. There are very real rewards and consequences to that.

Secondly, intelligence is not an indication of how smart someone is. Intelligence is only a measure of learning potential. How smart someone is results from both intelligence and practical application.

Finally, in psychology no other measure correlates with performance, health, and goal attainment as well as intelligence. I am not talking about IQ. I am talking about real world performance measures of multidimensional intelligence.

The article is almost certainly correct that the singular dimensional use of IQ has racial roots because it is biased to the administrators and against its test population. The supposed use of success in the article is highly dubious though, that reveals a poorly defined social construct.
