A study conducted on more than 1, 00,000 people found there are at least three separate components of brainpower and it is foolish to give a cohesive score for all of them.
The way researchers understand the complexity of the human brain has evolved, and so has the meaning of IQ, - what it really means, and how precisely we can capture it.
Researcher Adam Hampshire, a psychologist at the Brain and Mind Institute Natural Sciences Centre In London, is of the opinion that there are various types of intelligence. It is time to move on to using a more comprehensive set of tests that will measure separate scores for each type of intelligence.
In a new study conducted recently, 12 online tests were given to a few people to check their ability in various areas like reasoning, attention, and planning as well as information on the test takers' background and lifestyle. The entire test took around 30 minutes to complete.
The study found that there are at least three components that affect overall performance in tests. These include short-term memory, reasoning, and verbal recall.
"Potentially, we can measure a more comprehensive set of intelligences. 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."
"Based on the results of our study, it seems likely that IQ differences will vary in scale or even direction depending on the exact type of intelligence that the test or set of tests rely most heavily upon. I would suggest that it is both more accurate and informative to measure multiple types of intelligence", Hampshire says.
