Ready or not, here I come, you can't hide.
I'm sorry, guys, but I'm about to give away the greatest manipulation ever. Of course, this technique is used everywhere, but the best example is relationships.
Perhaps everyone has come across the following situation: you have a match with someone, things start looking up, and then he or she suddenly disappears. And then a couple of days later, "Hey, how are you?"
The "loss" technique. This way, the person stimulates the other's attention so the other will do everything in order not to lose again. Such a maneuver, by the way, is very common in business relationships.
