NLP (Neuro-Linguistic Programming) is a psychological approach that encompasses various techniques to understand and manipulate people. Three commonly used NLP techniques include cold reading, face reading, and body language analysis. Cold reading involves making general statements that seem specific and personal, allowing the reader to appear knowledgeable about the person being read. Face reading involves analyzing facial features to determine a person's personality traits and characteristics. Body language analysis focuses on interpreting nonverbal cues such as gestures and expressions to understand a person's thoughts and emotions.

These techniques can be used to effectively communicate and influence others.
