What technique is useful when interviewing witnesses about their observations?

The technique of allowing witnesses to let their memories flow without interruption is particularly effective in interviews because it encourages them to recall details in an unfiltered and natural manner. When individuals are given the freedom to express their thoughts and memories at their own pace, they are often able to provide more comprehensive and accurate information. This approach helps to create a comfortable environment, reducing the pressure that might come from more structured questioning techniques, which can lead to incomplete or inaccurate recollections.

Letting witnesses recount their experiences also helps to minimize the influence of interviewer biases, as well as reduces the risk of implanting suggestive information into the witness's recollection. This method is grounded in the understanding that memory can be a fluid and dynamic process, and it often benefits from an open dialogue rather than an interrogative approach.

In comparison to the other options, this technique is focused on encouraging candid sharing rather than challenging or directing the witness's narrative.
