Do people with smaller heads have smaller brains?
How can you fit the same sized brain into different size heads?

Do you have a small head?

You fold it.

Or deflate it a bit - depends on the type of brain.

And still they gaz'd and still the wonder grew,
That one small head could carry all he knew.

Oh I'd say there are plenty of people with big heads filled with air.

It depends on how old you are. What with Moore's Law and what-not, it seems on petaflops alone a 2015 six-year-old is ten times as intelligent as an 80-year-old retired career guidance teacher.

I have no idea what that word means, but I love it! Makes my brain all tingly when I say it

Of course. That's a no brainier.

Or is that just people with no heads?

Of course you'd say that, you have the brainpan of a stage coach tilter

Micheal McDaniel Proved that brainsize has an influence on how smart you are.

"Big-brained people are smarter: A meta-analysis of the relationship
between in vivo brain volume and intelligence Michael A. McDaniel"

In 1836, Frederick Tiedmann wrote that there exists ban indisputable connection between the size of the brain and the mental energy displayed by the individual manQ (as cited in Hamilton, 1935). Since that time, the quest for the biological basis of intelligence has been pursued by many. Various narrative reviews (Rushton & Ankney, 1996, 2000; Vernon, Wickett, Bazana, & Stelmack, 2000) and a metaanalysis (Nguyen & McDaniel, 2000) have documented a non-trivial positive relationship between brain volume and intelligence in non-clinical samples.

Finally, it resolves a 169 year-old debate. Tiedmann (1836) was correct to conclude that intelligence and brain volume are meaningfully related.

Heres an interesting one sure to cause some debate:

Since males have the bigger brains, they must have the smarts, right? In one study, scientists converted the SAT scores of 100,000 17- and 18-year-olds to a corresponding IQ score and found that males averaged 3.63 IQ points higher than the females

If there was a true causative relationship between large brain size and IQ then shouldn't elephants and whales be more advanced than us apes?

Birds have very small brains but can be considerably smarter than creatures with much larger brains.

There isn't a uniform brain size, same way there isn't a uniform heart or liver size.

I don't belieeeeeevvvvve it.

I think that it is the density of neural connections that is significant. More inter-connections among the neurons the greater the processing power.
Maybe one of the other scientists on AH can confirm.

Actually it's about the ratio of brain size to animal size, it's called the encephalization quotient.

So even though whales have massive brains, they have a ratio much smaller than dolphins and humans.

Birds on the other hand can actually have a better ratio to humans, but their small brain size also limits their cognitive ability.

I'm no expert, but I'm sure there must be a minimum brain size at which the EQ becomes relevant.

So normal people with big heads, yes could actually be naturally smarter.
Giant people with a head that is anatomically to scale with their larger bodies, not smarter than average.

What BizzyC said. Neandertals had bigger brains than us, but also had bigger bodies so their overall ratio meant their brains were the same size as ours or slightly smaller. They clearly weren't as inventive as us, so brain organisation comes into it too. They had much large visual areas in their brains so they may have had shortfalls elsewhere. Modern human brains have actually been shrinking in size over the last 40,000 years. The guys and gals who painted the caves in France, Spain and elsewhere were larger of brain and about the same body size, so their brains were actually bigger. Some have suggested they may have been brighter than us too, or rather their environment meant that they had to be masters of more things than we need to be today. We can afford to be more specialised. So today a highly intelligent "nerd" who isn't very practical in other areas can thrive, but back then he, or she would have been boned.

While it is certainly true that there is a dearth of sabre-tooth tigers to run from, and a similar scarcity of antelope that need running down and hommering with a primitive flint axe, it seems to me that a Renaissance Nerd should be well-able to Nerd about a variety of subjects, not just complex computer/engineering stuff.

The modern Nerd should be able to hack on computers, household electrics, car-servicing/basic repair, infant excrement-management, maritime navigation, bawling-child plamásery, truck-driving, Kenjutsu, dressing, table-manners, decent port and/or brandy, Ulster Fry cookery hi, and pint-lofting. Specialisation is for insects.

Brains don't even exist. Think about it - have you ever actually seen your brain?

I met it down the pub about six months back or that way. He was keeping well.

I talk to my brain all the time.

Sometimes it talks back.

Maybe some have been brainwashed and they shrunk so then you can have a big brain in a small head.

Sounds like a load of pseudo-scientific bunk to me.
