Deception is typically discovered because:
- a third party reveals the information (accidentally or not—see this humorous example – parrot talks)
- people stumble across information by accident (e.g., read an e-mail by mistake, make a surprise visit, etc.).
- gross inconsistencies come to light (e.g., caller id doesn’t match where partner claims to be, parking tickets contradict partner’s whereabouts, etc.).
- people take active steps to discover the truth
