Article in English: Priming is a psychological technique in which you frame a person’s thoughts or behavior in a certain way by employing particular words or phrases.  Your partner will be more cooperative and willing to help you if you prime them to admit they are honest.

Ask, for instance, “Are you sure that’s where you were?” or “What really happened?” If your partner offers you a story about where they were and what they did, retell their story incorrectly, and add some damning detail about their cheating behavior.  For instance, imagine you think your partner is having an affair with a coworker.  When you ask them where they’ve been, they might say they went out for drinks with their friends.  In reply, you could say, “Oh, you went bowling with your friends and coworker?”  They might reply, “I didn’t go bowling with my friends.”  In this case, your partner’s partial denial...
