Thanks. This reminds me of something I've found which works well in the short run. I admit I haven't checked for long term consequences.
It makes me crazy when people repeat themselves in short succession. If you listen, it's possible to discover that Waiting for Godot is more realistic than a lot of more interesting theater.
Hypothesis: People repeat themselves if they aren't sure they're being heard, or, oddly (and I've done this myself) if they're unsure of how what they're saying will be received.
Solution: Smile at the person and repeat back what they said. Your body language is "I was so interested I remembered what you were saying" not "I heard it already and I'm bored".
Observation: People stop repeating that particular thing. Yay!
However, they tend to seem a bit taken aback, though not hostile. I don't know to what extent they feel comforted and heard and possibly surprised because they weren't expecting that, and to what extent they've been embarrassed that their amount of repetition has been noted.

I have worked hard to stop doing this. As a teen I'd often repeat something when it wouldn't provoke a response. This is silly. I now realize that 9 out of 10 times the other person heard you perfectly well, so repeating what one said is counterproductive.
Also I've figured out that I should be louder. Everyone knows that one person who nobody likes because ze is too loud, but be...
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?)
