Joel Klein discusses the concept of 'authority gradient' in aviation and its implications in healthcare. This refers to the expertise levels within a team, such as a flight crew or medical staff. An authority gradient could lead to experienced members discounting inputs from less experienced ones, which could be crucial in crisis situations. In healthcare, this could contribute to unfavorable situations. Aviation manages high authority gradients by open communication and affirming everyone's value in their roles. This method is less common in healthcare but could be beneficial.
