4 ways to detect a lie

1. Watch body language.

People will often give away a lie in their facial expression, but some of these facial expressions are subtle and difficult to spot. Some people will change their facial coloration to a slighter shade of pink, others will flare their nostrils slightly, bite their lip, perspire slightly, or blink rapidly. Each of these changes in facial expression signifies an increase in brain activity as lying begins.

3. Listen to tone, cadence, and sentence structures.
