Genome entry #1 Intelligence

In Intelligence Robert Plomin and his colleagues did studies about specialized kids that are gifted. These kids are 12-14 years old. These students are the top 1% in their school. He wanted to see how their intelligence differ among humans. A blood test was done to test the intelligence. He discovered that the smart people have different kinds of genes, everyone has a different kind of IGF2R in their gene's pattern. Sternberg believe that there are 3 different kinds of intelligence, the first is analytic, creative and practical. Spearman later noticed that one student can excel from one subject but may do poorly on another subject, different from other students. Intelligence is different among different kinds of people, some believe that it is nurture and some believe that it is nature. Both are quite debatable.
