If you are always on the hunt for complacency, you will reward risk-takers, and people who thrive in uncertainty.
Take the mavericks in your service, the ones that wear rumpled uniforms and look like a bag of mud but whose ideas are so offsetting that they actually upset the people in the bureaucracy.
One of your primary jobs is to take the risk and protect these people, because if they are not nurtured in your service, the enemy will bring their contrary ideas to you.
