Can you tell if someone is lying just by looking at him? Distinguishing between veracity and deception, in both oral and written language, is a complex task that requires training to avoid bias and speculation. Linguistic and structural patterns of communication alongside specific micro expressions, leakage of facial emotions, using Paul Ekman’s Facial Action Coding System (FACS), can be detected as a result of carefully planned provoking questions during interview and interrogation.
Different methods for detecting deception and corroborating truthful accounts are examined in depth providing the most reliable, clear and useful ways to gain full access to today’s science to uncover hidden messages you need. Words, grammar, voice, style, and facial expressions can reveal all you need to get the truth, using research-based methods from the fields of psychology, linguistics, and criminal justice. Eliciting information, interviewing and interrogation are fully developed as tools to highlight detection of deceptive answers, ranging from personal to law enforcement settings.
