According to a Stanford University article, some studies claim that having a bigger brain means that you’re smarter. However, the article also mentions that brain size has a surprisingly small impact on intelligence and behavior. Having an unusually large brain doesn’t necessarily make someone a genius, and large-scale research suggests only a slight correlation between brain size and intelligence.
Another article from ScienceDaily also supports this claim. It states that bigger brains are smarter, but not by much.
On the other hand, an article from Inc.com states that on average, people with bigger heads tend to be more intelligent. However, size alone doesn’t tell the whole story. Research also shows that intelligence is not a function of how hard the brain works… but of how efficiently it works.
So while there may be some correlation between brain size and intelligence, it’s not necessarily true that having a bigger brain means you’re smarter.
What is the average size of human brain?
The size of the human brain can be measured by its weight, volume, or dimensions. The average weight of the human brain is about 3 pounds (1.3 to 1.4 kg)1. The average volume of the human brain is about 75 cubic inches (1,250 to 1,400 cm3). The average dimensions of the human brain are about 6.5 x 5.5 x 3.6 inches (17 x 14 x 13 cm).
On average, male brains are about 10% larger than female brains.
What is the weight of the heaviest human brain?
The heaviest human brain ever recorded weighed 2.3 kg (6 pounds 4.5 ounces) according to Guinness World Records. It was measured by Dutch pathologist Gerard Christiaan van Walsem in 1899, during the autopsy of an unnamed young man who died at the Meerenberg Asylum in Santpoort, near Haarlem in the Netherlands
What is the smallest human brain ever recorded?
According to New Scientist, a man with an unusually tiny brain manages to live an entirely normal life despite his condition, which was caused by a fluid build-up in his skull. Scans of the 44-year-old man’s brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue.
