Passage Summary: Don't make a choice if you're under-informed; keep researching until you actually know enough to decide properly.

Reasoning: If a person lacks the data required for a well-informed choice, they should avoid making a decision based only on what they currently know and should instead keep gathering information.

Analysis: This is a prescriptive principle that sets a high bar for decision-making. It tells us exactly what to do when we are in a state of ignorance: stop and search. When looking for a matching scenario, prioritize an example where a character recognizes their lack of information, refrains from pulling the trigger on a decision, and actively seeks out more data. The correct application will mirror this 'wait and research' structure perfectly.
