This is a great cold reading technique that works in magic tricks too.
You have some trick where someone needs to pick from 10 cards. And your patter goes something like "Picture the card in your mind. Ace of hearts. Ace of hearts" If they give a big reaction then you've found their card and performed a miracle. If not then you just continue "Of course, that's just an example..." and continue the patter throwing out other hints. Of course, it's tough to make this your only trick but it can really elevate a good trick to amazing.
Great example at 1.50 here: https://www.youtube.com/watch?v=QI5-NDiY7IM
