I'll give you the people and situations it is used in.
The head of the FBI international hostage program has made
this mandatory training for their operatives. Can't get much more intense
need to get this right when you have peoples lives at risk and an international media scrutinizing you.
It is used in securing contracts worth hundreds of millions of dollars with
companies that reside in a completely foreign culture to ours.
It has been used to go back and get higher prices after the contracts have been inked
which made the company "look bad for getting it wrong".
This two letter word carries so much power that your black belt negotiator buckles under it's force.
This all mighty word is NO.
What you do is say to your opponent that "if at any stage that this isn't right, let me know".
There are a few reasons why this works, which I don't have time to give now.
Just know it works in the toughest fields you could ever imagine...like those examples I gave you.
Yep, like a lot of common theory taught and regurgitated, asking for the "NO" is just the opposite.
As I said before, this has been tested where lives are at risk.
Who would you trust with your life?
