Back when I was at university, I took a class called "Decision Support Systems", which was about the creation of software systems to help in decision taking.

The teacher started the first class with this statement "Human beings take decisions with the liver instead of the brain. They take emotional decisions, and then they use the brain to justify and rationalize them." then he continued explaining how this systems should help to avoid that.

But that is what the letter looks like. Rationalization.
