Is there a way to tell when a person is lying?

Yes, there are several ways to determine if someone is lying. One of the most common methods is by observing their body language and facial expressions, as well as listening for verbal cues such as pauses or hesitations in speech. Another method involves asking questions that can be answered with either a truthful or deceptive response, which can then be compared against the actual answer given. Finally, it may also be possible to analyze physiological responses like heart rate variability or skin conductance levels, both of which tend to increase during deception.
