Would you mind clarifying, which sense of 'jarring' are you using? v.intr.
Also, what are the Dark Arts? (there was a mental flash of Yudkowky talking against misterianists, also rang a bell about PUA and Star Wars, so better ask than sorry)
Ok, after your clarifications: Yes, this does have a manipulative character to it. It just strikes me as a situation where the ideal honesty is simply not achievable. A group will have tacit beliefs and assumptions, there is nothing you can do about it. First come, first served.

Some prior considerations:
1) I mean "problem" in a very general sense, it could be a math problem, an existential problem, a social problem, an akrasia problem, a disease problem etc...
2) I'd like people to give informative/didactic responses. Try not only to state the facts, but also to help someone who'd encounter similar situations to be able to deal with them.
3) When talking about the one you didn't, give enough specifics that someone would actually be able to help you.
