This article is very hard to digest because of the writers switching of "intelligence" and "IQ". Intelligence =/= IQ. IQ is a score on a test, and intelligence is a vague set of mental skills and processes to solve problems of varying degrees and subjects. To say that they are equal is like saying that athleticism is equal to the number of pounds you can bench.
If the writer is talking about IQ, then these investigations aren't interesting, as IQ is a very small subset of intelligence (the ability to solve those types of problems on a test, which you can easily train for). If the writer is talking about general intelligence, then the writer really shouldn't be mentioning IQ at all, as it is notorious for being confused as actual intelligence.
