I have come to the conclusion that the main purpose of human life is to increase entropy by making errors. Years ago I was helping Citibank set up their computers for loans and had a bank VP ask me why I wanted to use check digits on the loan numbers since randomly the technique would only catch 1 in 10 errors. He had a funny look on his face when he was informed that humans make predictable errors and that the check digits would catch 100% of the errors they were most likely to make. The point is that student pilots have predictable behaviour that has to be trained out of them using the same technique that precedes most messy divorces, "Are you going to believe me or your lying eyes?".
