Good point. However cargo-culting other surgeons subtly and fashionably and well enough to fool promotion committees into overlooking mediocre performance might take more creativity than you think. For one thing surgeons are intelligent, status-oriented, complicated creatures. It's not just about picking the right clothing. Not giving the game away by your demeanour may require that you fool yourself too. Such narcissism might take a herculean effort to maintain because your ideas about yourself are connected to other, more objective, ideas. You might have to organise professional conferences and get involved in politics, which always take a psychological toll. If your attention is on the wrong things this could indicate that privately you don't believe your surgical performance is up to much or that it can be improved. Which may turn out to be a self-fulfilling prophecy.
