How to Recognize Warningand Protect Yourself

There isn’t a magic pair of questions that will always expose a liar—but there are two very effective types of questions investigators often use:

1. “Tell me the story again, but in reverse order.”

Liars usually rehearse a story in a normal timeline. Asking them to go backward (from end to beginning) makes it harder to maintain a fake story, so inconsistencies often appear.

2. “Can you give more specific details about that moment?”

Follow up with questions like: What time was it? Who else was there? What happened right before/after?
Truthful people can usually add details naturally, while liars may hesitate, contradict themselves, or stay vague.
