[The Second Take] Capture Nonverbal Cues to Unmask the Persona

People Who Deceive and Manipulate Others
Facial Expressions and Body Language Cannot Be Perfectly Controlled

Humans are skilled actors. From an early age, they make appropriate facial expressions to get what they want from their parents. During their growth, they often hide their true feelings in front of their parents or siblings. As adults, they wear masks suited to their roles. People do not recognize this as acting. Even the actors themselves mistakenly believe it to be genuine. As William Shakespeare said, "All the world's a stage, and all the men and women merely players. They have their exits and their entrances; and one man in his time plays many parts."

The film Confession is a crime story focusing on role-playing. Yoo Minho (So Ji-sub), the sole suspect in a locked-room murder case, vehemently denies the charges. Yang Sin-ae (Kim Yoon-jin), a lawyer who has never lost a case, suggests reconstructing the incident from the beginning for a perfect testimony. She points out each flimsy alibi to induce a full confession of the circumstances.

The words, gestures, and postures exchanged across the table are all acting. Yoo Minho pretends to be the victim, and Yang Sin-ae pretends to be the lawyer. Depending on the statements and challenges, their voice tones and attitudes subtly change. However, it is difficult to expect a tense psychological battle. Yang Sin-ae approaches the conversation having already traced some of Yoo Minho's traces. By giving trust with lawyer-like speech and expressions, she can find the puzzle pieces she wants. Meanwhile, the tension and fun of the role-play diminish, and the story falls into a twist.

Would the case fall into a maze if Yang Sin-ae had no prior information? Not necessarily. The masks people wear have cracks. True emotions and unconscious desires leak out little by little. It is impossible to perfectly control nonverbal signals such as facial expressions, voice changes, and body movements. People who harbor resentment or hostility show clear signs through body language. They suddenly frown, glare, or purse their lips and quickly relax them.

Sudden silence also says a lot. Those who hear words that provoke jealousy or hostility often fall into thought for a moment. They may hide it with a smile, but inside they are just as furious. This sends a signal of irritation different from simply being shy or having nothing to say.

Louis XIV used this to test the nobles. The nobles were skillful actors who often hid their feelings toward the king. Louis XIV would appear unexpectedly in their presence and carefully observe the fleeting expressions. If many uncomfortable signals were detected, he interpreted it as hidden hostility.

Most people are not Louis XIV. They are naturally easily deceived. This is because they want to believe certain things. Those who deceive or manipulate others thrive by exploiting this tendency. If people were not so easily fooled, humanity’s future would be brighter than it is now. However, it is impossible to change human nature. The best we can do is learn to recognize the signals that indicate attempts at deception, maintain a skeptical attitude, and verify more evidence. Robert Greene, known as a master of power tactics, advises in his book The Laws of Human Nature as follows:

"Whether attempting concealment or gentle persuasion, those who deceive others desperately try to prevent you from seeing the truth. While lively expressions or gestures may come purely from the other person's vitality and genuine kindness, if the person is a stranger or someone who might be hiding something, you must not lower your guard. At that time, you should look for nonverbal signals that confirm your suspicions."
