Then picking the exact correct thing
Your tongue is way more tacticle. We spend most of our toddler years discovering this.
You can look at anything around you, anyrhing, and your brain knows exactly what it would be like to lick it. Taste, texture, residue etc… it’s quite freaky
Oh and my thighs are really good at imagining my phone just buzzed.
inner or outer?

Siri, how do I unthink a thought?
Yeah, if you tilt your head back and pretend you’re shaking a salt shaker into your mouth, you will actually taste salt.
I don’t taste anything. Does it matter how hard I shake it?
When I was an adolescent, I dreamt that I performed oral sex on a woman by putting my entire head inside of her vagina. Turns out that cunnalingus is nothing like my premonition, but I certainly had the texture figured out.
There are 100% women who would be into that. I’m not saying they’re common, but I may have met at least one of them.
The area immediately before your hand is also really good at letting you know the time.
As a single dude, I can tell You, that’s not the only thing a human hand is good at.
Yeah, it’s really good at holding onto…hey, doesn’t that Look like a giant–
Dick, take a look out of starboard, it looks like a huge…
Also locating needed nightstand items in the dark of night
I must have gotten a defective one, then. My hand sucks at that.
Want to truly understand how good it is? Try getting a specific thing out of a pocket with a thick glove!
What’s in my pocket?
handses
Ohhhhhh, tricksy hobbitses. We hates them.
Lint.
Pocket sand
We’re also the absolute best at throwing.
There are over 1 trillion nerve ending in your hand
Just kidding I made that up
“And the average human only utilizes 10% of those nerve endings”
I disagree, if my pocket is busy I need to take things out to tell the difference between them. Also, my hands can’t tell the difference between my cards.
I wonder if this is an acquired skill. I’m reminded of working on cars and having to build “touch sight” where you “see” things hidden behind an engine block or other obstruction by feel alone.
Too bad that my brain apparently still can’t figure out the difference between they keys for my front door, shed and bike lock. Still requires 3 tries just like with USB sticks.
Maybe you could apply different tapes or something to the keys to tell them apart.
You can also scratch pretty much any part of your butt crack just by feel.
Idk… Sometimes I end up with nothing but keys in my hand and think I forgot my lighter just because the FOB for my car is the same shape and size as a BIC.
And human eyes are incredible at seeing things
Exactly correct!
Then picking the exact correct thing
It can easily tell what item is a coin, but how much that coin is worth is hard for it to do. (Trying to grab a nickel vs a quarter, etc.)

Euro coins have different knurling around the edge of the coin for accessibility reasons. It has the side effect of helping a lot when trying to find the right ones blindly in your pocket.
US coins too. Big, small, thick, thin, smooth, knurled.
Yeah I could definitely identify each euro coin by feel.
A nickel is smaller and thicker, and has a smooth edge compared to the quarter. Can you not tell the difference?
This guy fishes in his pockets with his hands.

When you’re jiggling around in your pocket for it and there’s other coins in there too, it becomes harder to do.
I’m not saying there’s a 0% chance of figuring it out by touch alone, just that by touch identifying a coin (vs a not-coin) is a lot easier to do than by touch identifying what amount an individual coin is worth. (In the U.S. at least.)

Here’s another: the human ear is phenomenal at determining where in 3d space a sound is coming from. Most animals can only determine direction and can’t really place a sound vertically. Watch what your cat or dog does when they’re looking for the source of a noise, it takes them a lot longer.

the human *ears. we need both ears working together to determine the source of a sound.
teamwork makes the dream work, people.

If someone wants to read an interesting (but complex) explanation of how it works
olafurp@lemmy.world 7 hours ago
One blindspot is that the ear is not good at determining whether the sound comes directly in front or back of the head.
terminhell@lemmy.world 21 hours ago
iirc it’s because human ears are slightly offset to each other vertically. The brain then calculates the time difference it takes each ear to hear it. Basically triangulation.

Triangulation is 2 dimensional, the 3 dimensional equivalent would be “tetrahedralization”.
davidgro@lemmy.world 14 hours ago
I’ve never liked this explanation because if that was all there was to it, it would still only localize to a slanted line in front of us.
Say for example the right ear is higher (I tried finding which one normally is, but couldn’t find a good answer) in this case it would not be feasible without other clues to tell the difference between a sound being higher up and slightly to the left, or lower and slightly to the right. It’s not a significantly different situation from the ears being the same height.
In reality there are other clues, largely based on the shape of our ears slightly changing the sound in learned ways based on the angle it comes from.
