A Common Mistake
Beware of assuming that people will behave logically. They often do not. Whims, biases, and "baggage" may drive them and the person who has carefully worked out how they will behave may prove to be as persuasive as a PowerPoint presentation at a rock concert.
All of us know that because all of us have seen it and yet, for many of us, our default mode is to assume logical conduct. Not a bad assumption up to a point but only up to a point.
Use two maps in your reasoning. One is the route that will be taken if logic is the guide and the other is the route if emotion is the guide. The roads may merge but it helps to know the route other than the one you would have taken.
