A personal anecdote that gives some credence to this theory:
Some years ago, after the Economic Crash of 2009, I attended a course in Progammable Logic Controllers which was designed to be a module for electrician's Continuing Professional Development. I, a Civil Engineer, had no background in this topic and said as much to the tutor. "Don't worry, he said, "the people with no experience nearly always do better than anyone else". This surprised me. It also surprised me when I came joint top in the course results.
People with experience can’t be asked doing the course because they know better anyway :) of course you do better because you probably take it seriously
