A good thinking tool shouldn't just hand users answers to their questions, but also guide and enable them to discover and articulate more complex questions.
Asking more complex questions, and discovering answers to them, which lead to even more nuanced questions. Without one, the potential of the other in this pair becomes limited.
A related thought: While building tools to solve hard problems for humans, we should strive to also improve people's depth of engagement with those complex problems and their solutions, as a way to preserve human agency when working with increasingly capable aids for our work. Otherwise, we risk losing touch with, and therefore understanding over, critical decisions.
