IQ Test For The More Complex Brain

This article states that the IQ test that we knew are not as reliable or accurate as we once believed. Since our brains have continued to develop and become much more complex we cannot give a single unified score for the three components of intelligence. A new study of 100,000 + participants suggest that there are at least 3 distinct components in measuring IQ. IN the study, all participants were invited to take a series of 12 online test that measure memory, reasoning, attention, and planning. The entire test takes around 30 minutes. According to the study there are 3 things that effect overall performance; short-term memory, reasoning and verbal recall. Lifestyle factors also come into play. Gamers have stronger reasoning and short-term memory, while people with anxiety don't do well with short-term assessments.

"Some very valuable research has been carried out using classical IQ testing. However, IQ is a massive oversimplification of the spectrum of human cognitive ability"

This means that the classical IQ test shouldn't be thrown out the window, but it can be modified to create more accurate measurements. John Gabrieli, a PhD professor of brain and cognitive science at MIT in Boston, reviewed the study.
“This is a really compelling study of an extraordinarily large number of people taking tests with a careful data analysis. It makes the case against the idea that IQ is localized in one part of the brain. We imagine that there is THE test of intelligence, but you can measure it in many ways. One measure may make a person seem super-intelligent, but if they picked another, they may seem average. There are multiple kinds of intelligence that can link to various tasks and different parts of the brain.”
It seems to me that there will never be a test that is completely accurate in measuring different components of IQ, because the brain is ever changing especially from person to person.
