One of the beautiful things about coding is the immediacy of the feedback. Screw up and your program crashes. Get it right and the machine does what you want. Tests turn green - that's nice. Subtle bugs can be deceptive, you might be thinking. True, but lots of bugs are not at all subtle. When you get good at coding, you get a lot of positive reinforcement coming from a machine rather than other people. What that does to our psychology seems worth considering. Might we also have the same feeling of "I'm usually right!" and might that feeling transfer to domains where it's not backed up by any real learning?
