The Two Questions That Can Reveal a Liar — And Why They Work

Have you ever had the feeling that someone wasn’t telling you the whole truth, but you couldn’t quite figure out why?

Catching a lie isn’t always about noticing nervous body language or avoiding eye contact. Sometimes, the most revealing clues can come from how a person responds to simple questions.

A popular idea circulating online suggests that asking two carefully chosen questions can make inconsistencies in someone’s story easier to notice. While no question can guarantee that someone is lying, the technique can be useful for encouraging a clearer, more detailed explanation.

Question #1: “Can You Tell Me Exactly What Happened?”

Instead of accusing someone directly, ask them to explain the situation in their own words.

The important part is to let them speak without constantly interrupting.

Pay attention to whether the story is reasonably coherent, whether important details change, and whether the person can explain the sequence of events naturally.

A person who is simply nervous may still tell the truth, so nervousness alone shouldn’t be treated as proof of deception.

Question #2: “What Happened Next?”

This simple follow-up can be surprisingly useful.

Rather than suggesting an answer, you’re asking the person to continue the timeline themselves.
