I am beginning to suspect that it is surprisingly common for intelligent, competent adults to somehow make it through the world for a few decades while missing some ordinary skill, like mailing a physical letter, folding a fitted sheet, depositing a check, or reading a bus schedule. Since these tasks are often presented atomically - or, worse, embedded implicitly into other instructions - and it is often possible to get around the need for them, this ignorance is not self-correcting. One can Google "how to deposit a check" and similar phrases, but the sorts of instructions that crop up are often misleading, rely on entangled and potentially similarly-deficient knowledge to be understandable, or are not so much instructions as they are tips and tricks and warnings for people who already know the basic procedure. Asking other people is more effective because they can respond to requests for clarification (and physically pointing at stuff is useful too), but embarrassing, since lacking these skills as an adult is stigmatized. (They are rarely even considered skills by people who have had them for a while.)
This seems like a bad situation. And - if I am correct and gaps like these are common - then it is something of a collective action problem to handle gap-filling without undue social drama. Supposedly, we're good at collective action problems, us rationalists, right? So I propose a thread for the purpose here, with the stipulation that all replies to gap announcements are to be constructive attempts at conveying the relevant procedural knowledge. No asking "how did you manage to be X years old without knowing that?" - if the gap-haver wishes to volunteer the information, that is fine, but asking is to be considered poor form.
(And yes, I have one. It's this: how in the world do people go about the supposedly atomic action of investing in the stock market? Here I am, sitting at my computer, and suppose I want a share of Apple - there isn't a button that says "Buy Our Stock" on their website. There goes my one idea. Where do I go and what do I do there?)
When I wear the device, there are eight motors positioned around my ankle. The one pointing most closely to north vibrates. As I move, there is sometimes some lag before a motor changes state, but when I'm still, there is always one motor buzzing, or else two motors kind of taking turns. (Actually, one of the motors doesn't work, because I burned the circuit board at its contact >< But that still tells me something.)
I'm not totally used to it yet--the buzzing is a little uncomfortable when it goes on for too long in one spot (like sitting in a car driving straight for several minutes). I think it might be an improvement if the motors were pulsed instead of continuous. But, if I am walking around, changing directions, it feels just fine. But I haven't been using it enough for me to feel a strong absence or blindness when I take it off.
How do I use the knowledge? One of my hobbies is geocaching. In geocaching, I usually need to look at a GPS receiver and a compass alternately, while also not tripping over roots and while looking around for my goal. I haven't gotten to try it yet, but with the ankle device (it's called North Paw), I'm hoping to reduce my visual burden by transferring some responsibility to my tactile modality.
