> what would really change if we removed the CEO and replaced him with the Janitor? I think this reads rather more out of the conclusion than the data can bear. It's possible (though I don't think plausible) that it's true, but the data is only based on people who were selected to run companies i.e. people who those doing the hiring saw to be a good fit. It says nothing about being run by a random person off the street, for which there is necessarily no data.
