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.
Eheran@lemmy.world 1 day ago
You mean the median? :3

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.

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

Are you joking?

Sadly, no. About 0.5% of our brain mass is microplastics.

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.

I’m an ugly bag of mostly water.

Fitting, really, to be a dream to meat.

Brain uses more wattage than a lightbulb, unless we are counting incandescent bulbs because it makes the stat seem more impressive.
disguy_ovahea@lemmy.world 1 day ago
It was estimated back when incandescent was standard.
Keep in mind that’s not accounting for energy consumed from neurons burning oxygen, which accounts for 20% of a human body’s consumption.
Tar_alcaran@sh.itjust.works 1 day ago
20% of your bodies energy is about 20 Watts.
Normal-weight humans burn about 2200 kilocalories a day, which is about 9.2 megajoules. There are 8640 seconds in a day, so that works out to roughly 100 joules per second, or 100 Watt.
SuperIce@lemmy.world 1 day ago
That phrase first came out when incandescent bulbs were the most common, so they consumed like 60W vs 7W for an equivalent LED bulb. The brain is somewhere around 20W.

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. Should have sayd energy.

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

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.
