what do you think /sci/?

75 IQ while still having 4x less brain

>> No.4202021

Certain physiological response from the body can result in such.

You should probably explain why it is first

Because his brain is 4 times smaller than the norm and still isn't that far below the rest of us. It was always supposed that brain size correlated with intelligence.
Not op by the way.

Probably garbage collector. No matter how you try to spin in, 75 IQ is Gump-tier.

Isn't that some strong evidence for dualism?

I think most of the cognitive operations are performed by the outer surface area of brain; the neocortex.

The brain is highly plastic in its early years. The developmental trajectory of the brain is dependent upon sensory input, which means that neurons adapt to some extent to whatever the local circumstances are during infancy. You can't lose 3/4 of your brain and be fine when you're an adult, but when you're young, your brain has the remarkable flexibility to compensate somewhat.

It is, but it's not the only determining factor.

Right, but subcortical gray matter structures are important as well, and the white bits are what connects different regions of the cortex to each other, and to subcortical gray matter structures.

The correlation between brain size and intelligence is weak, at 0.30 which is a shotgun blast on graphing paper. African Americans have slightly smaller brains on average, and have slightly lower average IQs. Asians have a very slightly larger brain than Caucasians, and have a very slightly higher IQ.

I personally think that the environmental effect explains the difference actually, since the different cultures and sub cultures value education differently. Even with a black child adopted by white parents, there are social influences like media and such that will cause this black person to adopt some harmful qualities of rap subculture.

Our IQ tests are also piss-poor because we don't fully understand intelligence. The reason that this man is quite intelligent, and why people with gunshot wounds to the head are still intelligent despite losing large chunks of their brain is because the human brain is largely redundant. Also, it is dynamic in the sense that brain "power" will be diverted to more important tasks. In this case, allowing this man to function as well as he needs to. I'm sure he suffers mentally in other not-so-important areas.

That's a misconception. There's no such thing as redundancy in the brain. Neurons that don't actively engage in communication with other neurons synapse with other neurons, retract their axon and grown a new one, or die. Compensation by other brain regions after a lesion does occur however, but that goes at the cost of less efficient performance of whatever brain region is compensating.

This would only be suprising if the gap between say a 75 and 100 iq was quantifiable in a manner that is not totally arbitrary. Then one could maybe assume it would be proportional.
Iq of 75 is monkey-tier.
