Detailed explanation-1: -An IQ score doesn’t measure your practical intelligence: knowing how to make things work, says Richard Nisbett, a professor of psychology at the University of Michigan. It doesn’t measure your creativity. It doesn’t measure your curiosity. It doesn’t tell your parents or teachers about your emotional readiness.
Detailed explanation-2: -The problem with IQ tests is that while they are effective at assessing our deliberative skills, which involve reason and the use of working memory, they are unable to assess our inclination to use them when the situation demands.
