Does a bigger brain mean you're smarter?

Did you know that a bigger brain can actually indicate that you are more intelligent? Not always. But the most recent study shows that intelligence and bigger brain sizes are actually positively correlated at .33+.  (The lowest score could be a -1 meaning there is perfect negative correlation and a +1 would have meant there was a perfect positive correlation.) Correlation does not prove causation but it is still interesting to think that sometimes a bigger brain does cause someone to be smarter!  When Einstein's brain was studied, it wasn't any heavier or larger in total size than a normal brain but the parietal lobe's lower regain was 15% larger than the average brain's! This just so happens to be the portion of the brain that processes math and spatial information!
