To comment more in the direction of this forum, I believe "research" like this is a misuse of cognitive measurement and does a disservice to anyone who struggles to advocate for a child who's an outlier of any type. The article was also extremely shallow and contributes to the culture of misunderstanding about testing and intelligence.
We get enough accusations of elitism.
One problem is that the testing isn't really quite measuring the right thing to begin with.
You are really trying to determine developmental arc, which is probably only partially correlated to IQ.
