Hide analysis

When interviewing witnesses to a crime, police interviewers seek to maximize the amount of information that a cooperating eyewitness can give them so that they can generate leads to follow, confirm or disconfirm . ███████ ███ ██ ██████ ███

Intro to Topic · Police interviews of eyewitnesses

Goal is to maximize the amount of true information from eyewitnesses. How do police do this?

Method 1 · Cognitive interview

Description · Development, adoption, and techniques

Success · Increases number of true recalls without increasing false recalls

Problem · Too hard to implement

Cognitive interview is complex. Too hard to learn. Too hard to implement. So it's great if it's executed properly but it's too hard to execute properly.

Method 2 · Hypnosis

Problem · May increase false reports; may increase false confidence; not all witnesses are susceptible to hypnosis

While hypnosis is easier to execute than cognitive interview, it has a lot of downsides.

Ideal Solution / Method · 3 criteria

1. requires no special training (better than cognitive interview); 2. can be applied to everyone (better than hypnosis); 3. has positive effect on true recall with no increase in false recall (better than hypnosis).

Method 3 / Ideal Solution · Close your eyes

Just tell witnesses to close their eyes as they are recalling.

Evidence of Success · "Close your eyes" is the best method

Improve true recall to similar degree as cognitive interview. Everyone can use this technique, unlike hypnosis. Doesn't require any specialized training, unlike cognitive interview.

This best captures the purpose, which is to describe the kind of information police interviewers seek to gain from witnesses. Confirming or disconfirming alibis is one way interviewers might try to use an interview procedure.
