Something that worries me slightly about it is that people are shockingly lousy at guessing how they are going to behave in future, so the question has two layers of abstraction: how the world will be, and how they are going to potentially feel.

One way my former manager taught me how to derive this information is to ask the user to design their ideal product ... I know, I know, but hear me out ... so you start the interview with what they're doing right now and the problems they encounter, and what they're currently doing to solve it. Then you ask them to sketch or write down their ideal solution which could be absolutely anything. Then, you get them to compare the current reality with their imagined ideal, and tell you about the gaps.

In one interview, my participant drew (for an edtech product) a chair that would give you electric shocks every time you got the answer wrong! Ah, they are looking for feedback. The gap with the current reality is the lack of instant, individualised feedback.

I never had to ask them to prioritise their imagined wishes, but they volunteered the information that their most important wish was to be told, there and then, what they're getting right.
