On a related topic, competence, I have come to realise over time that I and many people I know have a bias towards people in professions they don't know much about, believing that most of them are good at their jobs. Reality is that as the case with general population, majority are incompetent, careless, and well, downright stupid. Be it doctors with a decade long training/education, plumbers, lawyers, programmers, etc.
