 We used to do these drills in the CIA war gaming drills, right? We were doing the classroom training, which was, you know, like a year long, basically, of just sitting around and getting into all these different national security scenarios. Not a year long. It was less than that. But anyway, it was a long time. And one of the things we would do is we would go through these mirror imaging exercises. And the basic lesson was, don't think that somebody else will act under the same circumstances the way that you will. Understand who they are, because then you'll know how they will act under the circumstances that you are trying to analyze, right?
