9. Aim High
Trick: Ask for way more than you want at first then scale it back later.
This trick is sometimes known as the door in the face approach. You start by throwing a really ridiculous request at someone—a request they will most likely reject. You then come back shortly thereafter and ask for something much less ridiculous—the thing you actually wanted in the first place. This trick may also sound counter-intuitive, but the idea behind it is that the person will feel bad for refusing your first request, even though it was unreasonable, so when you ask for something reasonable they will feel obliged to help out this time.
Scientists tested this principle and found that it worked extremely well as long as the same person asked for both the bigger and smaller favor, because the person feels obliged to help you the second time and not anyone else.
