It is crucial to remember that detecting lies based on body language or facial expressions is a complex and often unreliable process. People can exhibit various signs for various reasons, such as nervousness or discomfort, which may not necessarily indicate deception.
The most accurate way to detect lies is through careful examination of the content of the person's statement, asking follow-up questions, and cross-referencing with available facts or evidence.
If you suspect someone is being dishonest, it's essential to approach the situation with empathy and understanding, while focusing on gathering more information to make an informed judgment. Jumping to conclusions based on body language alone can lead to misunderstandings and unfair assumptions.
