A member asked:
Is there any correlation between skull/brain size and intelligence / iq / etc.? also does bigger head = bigger brain?
11 doctors weighed in across 3 answers
No: There are lots of people with large brains but they're not geniuses. Conversely, lots of people with small sized brains are out there who are really smart. It's all what you do with your brain and how you put things together. Some are gifted but this doesn't correlate with brain size.

Not too much...: Higher IQ is better correlated with the density of brain tissue; meaning, the more packed and populated an area of the brain is with neurons, the likely the more intelligence there will be. Many studies suggest that it is not only gray matter that counts, but also white matter. Einstein's brain was only about 90% the size of the average adult male brain, yet, look what capacity he had...

No.: If your brain is within the normal range, there is no correlation. And a bigger head does not necessarily mean a bigger brain, because head size is related to skull size, and skulls can be of variable thickness and have other anatomic variations.
