Aren't smaller, better-connected brains more likely to be from an intelligent person? I'm not sure there's a relationship between intelligence and brain size in general.
Also, huge head does not imply large brain inside the head.
missing big pieces usually makes it work less well.
folds and creases seem good?
Not too much fluid!
Not too little either!
front part seems pretty important for thinking.
middle too.
"stuff" in the brain is almost always bad for thinking. Like rocks and things. Neurons, blood and the right blend of fluids are great.
phrenology is pretty wrong. Like, super wrong.
Beyond that, we know a bunch of stuff about brains and neurons and how they all piece together, but just based on lookin', we're pretty bad at judging a person based on their head and brain.
I have a big head (I needed to pick the bigger helmets when I went gokarting) so yes, there is a huge relationship between IQ and brain size. Don't mock my chunky noggin please.
That you felt to point out what you think is a mistake shows me you have an inferior skull. You might even have the blood of the worst people (The Dutch, the creators of the infernal word LOL, Colonizing the sea, and Big Brother (potjandorie nog aan toe!)), in you. :P
