Spot on. I think this can be applied to having tests also and arguably agile/XP. Something everyone on HN is going to agree on is having tests and having a good test coverage. But why? Why should I if I am a newbie? Because our experience has given us a headache and tests have been the asprin that makes sure that these headaches don't occur again. Arguably agile because many people here don't believe in it. Why don't they believe in it? Because they have never had the headaches it is meant to help, or they have never tried it when they had the headache, or someone else on their team had the pain and not them.
