How do you detect lies in D&D?

In D&D, you detect lies primarily through player roleplaying, using Insight checks against Deception/Persuasion, and leveraging spells like Zone of Truth or Detect Thoughts, as there's no universal "lie detection" mechanic, requiring Dungeon Masters (DMs) to focus on verbal cues (vague, overly detailed stories), body language (fidgeting, eye contact shifts), and inconsistent narratives, similar to real-world techniques but within game rules. Players often ask for Insight rolls to gauge truthfulness, while DMs look for patterns of dishonesty or cognitive load indicators.
