A little room to think
One clearer reading question.
Knowing when a question was chosen helps explain what an answer can do. A question set before examining results gives the investigation a stated target. A question that emerges while exploring results can open a useful new direction. The distinction matters because an appealing pattern could help choose the very question it then appears to answer. Keep that sequence visible. Ask whether the interpretation concerns an original target or a new lead, and what a separately planned check would contribute. Exploration can remain valuable without being presented as a completed test.
Questions to keep nearby
- Was the question chosen before the results were examined or during exploration?
- Could the pattern have influenced which question received attention in the report?
- What would a separately planned check add to the interpretation of this new lead?
