    Your tongue is also super tactile. We spend most of our toddler years discovering this.

    You can look at anything around you, anything, and your brain knows exactly what it would be like to lick it, even if you’ve never done it before. Taste, texture, residue etc… it’s quite freaky

    Oh and my thighs are really good at imagining my phone just buzzed.

    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.

      One blindspot is that the ear is not good at determining whether the sound comes directly in front or back of the head.

      the human *ears. we need both ears working together to determine the source of a sound.

      teamwork makes the dream work, people.

      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.

        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.

        Triangulation is 2 dimensional, the 3 dimensional equivalent would be “tetrahedralization”.

    Want to truly understand how good it is? Try getting a specific thing out of a pocket with a thick glove!

    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.

      Human balls are incredibly great at feeling immense pain at even the slightest slap with a riding crop.

      A nickel is smaller and thicker, and has a smooth edge compared to the quarter. Can you not tell the difference?

        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.)

          Well, sure. Adding many variables usually makes anything harder to do. But that generally just means it takes a little more effort.

          Are your hands horribly mangled or something? Am I bringing up something hard for you to deal with?
