Red Badger :" “Most people are aware that humans have unusually large brains – significantly larger than predicted from our body size. "

Learning to do more , .. with less brain size
It's what Socialism teaches us !

[Red Badger]

True.....................

beer goes back some 4500 years in Iran, etc.

the reason brains shrunk was the founding of the Demo party

[Little Ray]

Beer is the reason for civilization.
So maybe civilization or a more sedentary lifestyle caused it.

[WMarshal]

To sum it up, civilization will eventually render the great mass of humanity into mindless drones.

[M Kehoe]

Beer, bacon and beans?

Pork, potatos and pudding?

Or Moore’s law?

Agriculture is what made our brains shrunk. When you can stay in one place and provide for yourself, you don’t need to remember topography or weather patterns like you do as a nomadic hunter.

Quality vs quantity

[GingisK]

Maybe our modern brains are fabricated using a more highly advanced, yet smaller brain cells. Similar to developments in integrated circuits.

Yes, not that agriculture itself didn’t make people dumb, but the more consistent availability of calories allow for specialization and trades. In essence “civilization” as we know it is about collective specialization. You give up jack-of-all-trades for laborers, artisans and professionals. They still need to use their cerebral cortex, but once they have their jobs down pat, I’m going to bet their EEG readings flatten out a lot.

“The premise of this hypothesis is very intriguing. “

It has been around for a long time. For a fun read, look up C.M. Kornbluth’s The Marching Morons, a short story from 1959. It is the precursor to the movie, Idocracy. The logic of both is inescapable.

[Grampa Dave]

Liberals on welfare, free medical care, food stamps, lodging, watching ABCNNBCBS and being told, and who to vote for, don’t really need a big brain.

Their some what elected Resident even tells them when to get vaccinated, and who to hate.

Having a brain big enough to protest what your child is or isn’t being taught at public school is now a dangerous terrorist activity as per our AG!.

Then, regular daily drug use shrinks their unused brains even more each day.

So liberals don’t need a normal IQ or big brain.

So liberals have been around for a while now. Who knew?
