A Bigger Brain Doesn’t Mean a Higher IQ

Researcher’s claim according to which there is no connection between brain size and a higher intelligence is based on simple evidence. Men have larger-sized brains than women, but they are not more intelligent. As a matter of fact, in 2012 researchers discovered that women get higher scores than men when it comes about IQ tests.

A bigger brain doesn’t mean a higher IQ, study reveals.

Many people think that a bigger brain would lead to a higher IQ, but that seems to be just a myth. A recent study revealed that the brain’s size has nothing to do with intelligence.

The study was published in Neuroscience and Behavioral Reviews and shows no link between a larger brain and IQ. The study was made by scientists from Austria, Germany and the Netherlands and it was made up of both published and unpublished studies which involved approximately 8,000 participants. They confirmed that the brain’s size has nothing to do with the IQ.

Jakob Pietschnig, the study’s lead author, claimed that even if a slight connection could be noticed, the size has little relevance.

Researchers analyzed 148 brain samples from both men and women and were able to observe that even if there is a small connection between brain and IQ, one’s intelligence is actually given by the brain’s structure.

“Brain structure and integrity appear to be more important as a biological foundation of IQ, whilst brain size works as one of many compensatory mechanisms of cognitive functions,” Pietschnig declared.

To put it simply, the size influences only rapidness that makes the cognitive function complete.

But what’s the reason people believe the brain size is connected to a bigger IQ? Researchers believe that one reason is the 150 years of people believing that due to several publications.
