- This is a CIA presumptive interrogation technique. You bluff to see their reaction.
HOW TO DO IT :
- Sit them down, look disappointed, and say calmly: 'I know exactly what's been going on. I wasn't going to say anything, but someone sent me the screenshots. I just want to know why.'
WHY IT WORKS :
- If they are 100% innocent, they will get confused and angry ('What screenshots? What are you talking about?!').
- If they are guilty, their brain will instantly try to figure out which secret you found out about. They will usually pause, look down, and try to do 'damage control' by admitting to a smaller piece of the truth ('Look, I only texted them once...'). You just caught them."
