- This technique is used by intelligence agencies to find a leak. It allows you to know exactly who is betraying your trust.
HOW TO DO IT :
You need to feed a specific piece of fake information to the person you suspect.
Choose a fake secret that is believable but specific (e.g., 'I’m planning to quit my job next month' or 'I’m secretly dating [Name]').
Tell this secret only to that one person.
Tell a different fake secret to other people if you have multiple suspects.
Wait.
WHY IT WORKS :
If that specific rumor comes back to you from someone else, you know with 100% certainty who the leak is. You caught the rat red-handed.
