#4 – Defensiveness
Two of the most popular tricks in the Liar’s Handbook are projection and deflection. For example, if a person is cheating on their partner then they may accuse them of infidelity when confronted. Becoming aggressive and spreading accusations around is often an attempt to intimidate the person asking questions and (hopefully) end or derail the conversation. Watch out for raised voices, allegations, and manipulation (“don’t you trust me?”) when you confront a person about wrongdoing. If a mild conversation rapidly escalates into an argument or a list of accusations, the chances are that the person you are talking to is hiding something.
