15 Ways to See Through Lies

2. Watch for inconsistencies.
3. Be alert to vagueness.
4. Read nonverbal reactions.
5. Ask direct questions.
6. Don’t disregard lies to other people.

With that in mind, here are some signs that someone might be lying to you:

1. People who are lying tend to change their head position quickly.
2. Their breathing may also change.
3. They tend to stand very still.
4. They may repeat words or phrases.
5. They may provide too much information.
6. They may touch or cover their mouth.
