In my experience, the ones who most fervently believe they have such “clues” are, in fact, lacking them. I can’t tell you the number of times I’ve encountered engineers who become indignant when someone tries to redirect them to safe, scalable, and operable ways to solve problems. What they often want is to have the problem solved their way because it would be less work for them or otherwise advance their own personal interests, regardless of the problems doing so would create.

Can confirm, I had a coworker doing that a while ago and it was incredibly frustrating. After going through the whole quizzing you still end up with no answer to your actual question, as if they were more interested engaging with their own process and not what you were actually asking

Exactly.

Back when I worked at Google there was an internal page someone put up that denoted what they called "the YX problem": the observation that the XY problem, applied to a sufficiently great extent, creates an environment where more productivity is lost convincing one's interlocutor that X is in fact the correct problem to solve than would be lost by chasing X and having to later pivot to Y if that turned out to be wrong.

It's extraordinarily aggravating when it happens. I really wish it was something we talked about more.

Your way is good because it answers my question first. I've been wanting to do a weird thing X and had to first spend half an hour convincing people that yes, I really do know what I'm doing, so they'd give me the one-liner answer I came for.

Ultimately, it should be on me to choose whether I want to risk doing X or whether I want to take up your offer to explain Y, not the "as a favor to you, I'm not going to tell you how" way you described.
