Are bigger brains better?

Do people with a small head (like myself) have a lower amount of intelligence? There’s a very weak, spurious correlation. This correlation is probably due to the effect of childhood malnutrition on both intelligence and general body (including head) size.

In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. … Thus, on average, a bigger brain is associated with somewhat higher intelligence.

What does a big head indicate?
