The useful starting point
A stronger prompt invites an account, then clarifies it. It does not insert an action, motive, or cause that the witness has not established.
Find the assumption hidden in the question
Consider this prompt: why did the delivery worker ignore the warning? It assumes a warning existed, the worker noticed it, and the worker deliberately disregarded it. None of those facts is supplied in the exercise. A long answer to that question may still rest on its unsupported starting point.
For study, underline the assumptions before rewriting. Ask for the person's own description first, then clarify details of that account. The goal is to understand what the person recalls, including the limits of their view, rather than obtain agreement with a prepared explanation.
Rewrite a fictional interview prompt set
In the scenario, a stack of empty trays shifts while people are arranging a display. Witness A was at the room entrance. Compare the questions below.
| Suggestive prompt | More neutral prompt | Useful distinction |
|---|---|---|
| The stack was too high, wasn't it? | What could you see of the trays from where you stood? | Observation before assessment |
| Who rushed the setup? | Describe what you saw happening before the trays shifted. | Actions before motive |
| Did the noisy room distract everyone? | What do you remember hearing? | Reported sound before inferred effect |
The revised questions allow answers that differ from the interviewer's initial theory.
Clarify the account without filling its gaps
Suppose A answers: someone said the stand was unstable. Useful follow-up separates the speaker, the timing, and what A personally perceived. Ask which part A heard directly and which part A learned afterward. If A cannot recall, record that limit instead of offering a name for confirmation.
When A describes a location, ask them to explain it using the supplied classroom diagram. Do not infer that being nearby means having an unobstructed view. A summary such as you heard a comment after turning toward the room should be offered for correction, not treated as a settled fact.
Review your notes for words the witness did not use
After the fictional interview, compare the notes with the supplied responses. Remove unsupported additions such as careless, impatient, or obviously. Retain relevant uncertainty. If a summary changes after clarification, preserve a clear version history rather than silently making the earlier note appear more precise.
CCOHS recommends open questions and avoiding leading prompts. This exercise develops that narrow skill; it is not a qualification to conduct a real investigation. Real interviews require the organization's authorized process, appropriate support, and applicable requirements. Keep your classroom exercise focused on question quality and accurate attribution.
Check your reasoning.
Rewrite this prompt: You saw the worker remove the sign because it was in the way, correct?
Open the suggested reasoning
Start with: What did you see happen to the sign? Then ask where the witness was and what happened next. Do not supply the actor or motive unless the account establishes them.
