The "I thought you were good, but it turned out to be..." technique.The essence of the reception - in the designation of the opponent's positive qualities, which you "knew", on which "counted", but "it turned out all wrong".
The meaning of the trick is inducing in the opponent a strong emotional experience, which will prevent him from negotiating in a balanced way.
For example:
- I was practically sure that I had found what I wanted, but this act of yours ruined your entire positive image.
