>> Getting good at it seems to be a matter of methodical practice.
Yes, but I can practice moving my eyebrows to achieve mastery, because I know how to move them at least a little bit. With my ears, I literally cannot - no matter how hard I think about it or how much I strain, they just won't move. So how can you practice something that you cannot do at all? Just "try harder"? I feel like that's like telling someone with no legs to practice walking.
Maybe tiny shocks like with a tens system, or a pinch, used to jolt your nerves into recognizing the location? I had a lot of trouble with my eyebrow arching, but eventually got it by poking it with a straw or pushing it around with my finger.
Or maybe there's a genetic component, like tongue rolling. The nerves and muscles are there, no sensation seems to be lost, they're just arranged a bit different.
Kinda cool how something trivial can go into these weird rabbit holes, anyway.
