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.
I've seen plenty of people rationalize not wanting to learn a new thing with those words.
The thing is, this is a rationalization too. It may be true, it may also be false. The only certain thing is that they don't want to learn a new thing.
That said, this happens in small circles, where you know the context of the person asking the question. People assuming they know why a stranger is asking something tend to be wrong too.
