Intelligence. What is it? How can it be determined? How can we measure it? Chapter Nine takes an in-depth look at the concept of intelligence. The text makes it very clear that there is not set definition for intelligence. In fact it seems as the definition is all relative the person asking the question, making a correct definition nearly impossible to attain. Many of the determinants that are supported include, but are not limited to sensory capacity, abstract thinking, "thinking on ones feet", and ability to attain knowledge. While these ideas all hold true in terms of defining intelligence, determining what makes these things present is a little bit tougher. Many scientists have tried to determine what makes us intelligent by putting them into domains. The Triarchic model, developed by Robert Sternberg, divides intelligence into three parts, analytical, practical, and creative. Lastly, there are many supported biological explanations such as the size and structure of the brain.
The first to questions were answered early in the chapter, however the majority of the chapter goes into deep detail of how to measure intelligence. The IQ is the focus of this chapter which is defined as, "systematic means of quantifying differences among people in their intelligences." While the chapter shares how the test has created and has been evolved into a key part of our society, I found the "influence of genetics and environment on IQ" section the most interesting. Specifically the question "Does Schooling make us smarter?" was asked. I thought it was very intriguing that studies supported this unbelievably, with some surprising evidence. It shows that children who have an extra year of schooling have higher IQs, summer vacations lower our IQs, and dropping out lower ones IQ.
With an election just around the corner, education is a heavy platform for many of the candidates. I think it would be interesting if our country took a focus on developing children's IQs in school in order to ensure them a brighter more successful future. This information in this chapter shows that we can not only determine and test IQ but that we can develop. To me, a more intelligent country is vital to our future in the vastly changing and growing world.
