Judges detect lies by looking for inconsistencies in testimony, comparing statements to evidence (documents, texts), observing non-verbal cues like body language and eye contact, and noting verbal tells such as repeating questions or vague answers, with a focus on factual contradictions being more reliable than behavioral signs alone, using cross-examination to poke holes in fabricated stories. They don't rely on one single sign but build an overall impression of credibility from patterns, external evidence, and internal logic.
