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?)
I am terrible at remembering names. This is bad in itself, but exacerbated by a few factors:
I regularly have lengthy conversations with random strangers, and will be able to easily summarize the conversation afterwords, but will have no recollection of their name.
I am fairly noticeable and memorable, so even people whose names I have no reason to know will know mine.
I am not particularly good with faces either.
This isn't a memory problem, I can quote back conversations or remember long strings of numbers. I often cope by confessing to my weakness in a self-deprecating manner, or by simply not using names in direct address (it's generally not necessary in English), but these don't actually help me learn names. If I remembered to ask their name early on, I sometimes pause mid-conversation to ask "Are you still x?" but that is somewhat awkward and I'm wrong half the time anyway. The only time I can reliably remember is if they share the name of an immediate family member.This is bad enough that I'll sometimes be five or six classes into the semester and have to check the syllabus to figure out the professor's name, or will have been in multiple classes with someone and shared several conversations and still not know their name.
I've had good results with flashcards. One side write a person's name, and on the other write conversation details, physical descriptions, and mnemonics for physical descriptions. A few days of reviewing that Michael Jones is a friend of Lisa's who a grad student at Brown studying Fluorochemistry and looks a bit like O'Brian from Star Trek, and you'll probably remember his name (and other tidbits about him too).
