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.
Based on my neurology classes, I feel like we have some idea what some parts of the brain do. Obviously full on experiments would be unethical, but we can like, observe which neural pathways formed in people with the same life style (so Taxi Drivers have larger and more developed sections focused on navigation). We can observe what happens to people who take the same kinds of damage, and occasionally we get lucky and we can see what happens to people with grievous injuries or rare maladies. Also, we can do experiments on creatures like snails which far less complex brains.
The brain is certainly an interesting a weird black box, but we do have outs to learn some things
Oh, totally. We legitimately know tons of stuff about brains, including what most parts are typically used for. We just can’t tell much based on eyeball lookin’, we’ve gotta get in there with FMRI and EEGs.
I’m purely referring to head/brain size or gross physical properties and how they relate to intelligence.
Show a neurologist a photograph of a random brain and ask them to assess the owners intelligence.
The only thing they really have to go on is that if you can photograph someone’s brain, signs aren’t typically looking great for them.
They’ll be making guesses based on vague correlations, and also getting fidgety about what you even mean by intelligence, since that’s also not a simple measure.
Oh, I forgot to mention that we can also do some weird experiments with rats. Teach a bunch of rats how to do a maze, or complete some task, and then surgically remove different bits of each of their brains.
Unless you really mess them up, they usually remember how to do the maze.
Yeah, brain plasticity is really fascinating. One of the guys I work with, its the only way to teach him anything. He had a heroin overdose like 15 years ago. He has basically no short term memory, but I’ve been able to get him to retain things via repetition. Mostly repetitive physical tasks, but social media, with advertisers constantly pinging him, has also been a very powerful reminder. He’s big into the EDM scene and he remembers events, both past and future, because social media keeps buzzing him and reminding him. I wish there was a way to harness that power for good.
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

Our brain shape science basically boils down to:

I fucking love science.
instructions unclear; adding rocks to brain for hard thinking
Tired of people stereotyping metalheads as dumb smh
No! That will probably do something bad! Or nothing, depending on complex factors we’ve not totally figured out!
At least wash it first and take some before and after images.

It’s why missing a chunk won’t make the neurologist definitely say it’s impaired someone’s intelligence.

It’s an extreme case, but definitely indicative of how visual examination is just not great for assessing brain function.

But obviously, I’ve never seen his brain before.

N = 1
Look out, this guy’s most people.
uses my superior vision, no caliper needed

My mom dropped me on my head when I was a baby and I still have the dent.
Don’t worry only skull size on birth matters, else we could just take normal kids and inflate their skulls with pump.
Jesus christ mate, they’re listening! Don’t give them ideas!
We have seen what they think we talk about vs what we actually talk about, and they def are not listening ;)
Soy irl
I said please no bully, y you bully?
it’s a compliment boo 😘 <3 u habibi
I don’t know who that is. I still use a rotary phone.

@henfredemars Indeed, it is often associated with hydrocephalus, a condition rarely conducive to cognitive performance.
