The document discusses various methods for detecting deception, including non-verbal and verbal clues that may indicate lying, such as nervousness, hesitation in speech, and failure to maintain eye contact.

Additionally, techniques like lie detectors and MRI scans are mentioned along with behavioral indicators that correlate with deception.
