Baseline Changes for Lie Detection

Last week I asked you to baseline people – see what people look like when they’re telling the truth. In lie detection, you’re looking for baseline changes. The baseline changes could be physical changes, emotional changes, or auditory (vocal) changes. If you’re speaking with someone and all of a sudden they change, pay attention. Maybe they feel uncomfortable with what they’re talking about or maybe they’re not being 100% truthful with themselves or with you.

Examples of Baseline Changes

If the person normally speaks slowly and they start to speak quickly and stumble over their words, then this is a baseline change.

If the person normally relaxes and sits back in their chair and they sit up rigidly, then this is a baseline change.

If the person normally uses a lot of gestures when they speak and they stop using gestures, then this is a baseline change.

Baseline Change Homework

Firstly, observe a person’s baseline (when they are telling the truth) and then secondly, look for cues that their baseline has changed.

When you see baseline changes, pay attention and dig deeper.
