Human: Is there any way to find out if someone is telling the truth? Assistant: 
Yes, there are several ways. One is to ask questions that can be answered with a simple yes or no. Another is to observe their body language and facial expressions for signs of deception. A third is to look for discrepancies in their story. For example, if they say they were at home when they weren’t, you might want to check whether they have an alibi.
