Contrary to popular belief, we're all profoundly stupid. Even the smartest among us spend enormous effort in their struggle to comprehend our surroundings.

At least half of us are below average.

But in a perfect bell curve, isn't the median always the same as the average?

And even if it's not a perfectly symetrical bell curve, aren't they generally close enough to ignore the differance

It's not. I assure you there are far more outliers on the low end.

[–] milicent_bystandr@lemm.ee 8 points 4 weeks ago (1 children)

I endeavour to be as stupid as possible so more people can be above average.

[–] Imgonnatrythis@sh.itjust.works 5 points 4 weeks ago

America thanks you for your service.

If we're talking about IQ, than no. An IQ between 85 and 115 is considered average. This entails 68% of the population. So, only 32% of people are not average and only 16% are below average.

Maybe the brain will one day invent something more tiresome than watching reddit users exchange tautologies.

I often describe myself as "3lbs of mostly fat piloting a meat mech." To the point that my wife sometimes refers to injuries as malfunctions/damage to her meat mech.

[–] LillyPip@lemmy.ca 7 points 4 weeks ago

I’m an ugly bag of mostly water.

Fun fact, the average adult brain also has a credit cards worth of plastic inside. So that bacon has some company!

Additionally, the average brain is about 1300 grams. 0.5% of 1300 is 6.5 grams, and plastic credit cards weigh roughly 5 grams.

0.5% is really hard for me to visualize. A credit card in everyone's brain is unfortunately easy.....

Once I put my head up to the EFTPOS machine and the payment actually went through

[–] voracitude@lemmy.world 14 points 4 weeks ago

EFTPOS is the fastest payment system in the world for identifying Australians on the internet. If you need to camouflage, you can use "card reader" instead. I don't know when you'd need to camouflage like that, but these are interesting times.

If we are talking facts, neurons don't use electricity, it's a cascade of released ion potentials. Thats why nerves are so much slower than electrical signals.

[–] psud@aussie.zone 16 points 4 weeks ago (1 children)

He should have said "power" not electricity

Humans dissipate power in the range of old tungsten lamps - on the order of 100W at rest, brains use about 20% of that, so 20W - about the same as an energy efficient globe

[–] Kbobabob@lemmy.world 4 points 4 weeks ago (1 children)

Hi. I'm just curious what part of the world you're from that light bulbs are called a globe?

Cheers.

[–] psud@aussie.zone 4 points 4 weeks ago (1 children)

Yeah we call them light globes in Australia, as well as bulbs

[–] Kbobabob@lemmy.world 3 points 4 weeks ago

Thanks. Never heard it before

[–] SoleInvictus@lemmy.blahaj.zone 16 points 4 weeks ago

It's really both, neurons communicate electrochemically. Neurons establish a voltage difference across their membrane, typically positive outside, negative inside, by concentrating ions on one side or the other. In a single neuron, the action potential (signal) results in the electric polarity of the cell membrane switching to negative outside, positive inside, with the change in gradient cascading down the length of the axon as ions are allowed to flow across the membrane by voltage-gated ion channels. After depolarization, ions are actively and selectively pumped to either side of the membrane, repolarizing it.

There's a lot more to it than that but it's 100% charge dependent. The change in charge is mediated by the flow of ions across a membrane instead of the flow of electrons through a conductor, hence why it's slower.

Fitting, really, to be a dream to meat.

I Upvoted just for the tapioca mention

[–] MintyFresh@lemmy.world 3 points 4 weeks ago

Tapioca does sound good.

You momma is FAT (with water and salt)

[–] espentan@lemmy.world 14 points 1 month ago (1 children)
[–] kautau@lemmy.world 11 points 1 month ago (1 children)

Yeah your momma’s so big she’s not even FAT she’s exFAT and can store files up to 120 petabytes

[–] rmuk@feddit.uk 8 points 1 month ago

Yo mama's like exFAT; she's got no permissions so anyone can access anything and her low requirements mean she gets embedded everywhere.

[–] weariedfae@lemmy.world 4 points 4 weeks ago

But poltergeist cat is real!
