“Once randomly aggressive behavior gets started in an organization, it tends to be contagious, rapidly spreading itself because of a built-in mammalian device for relieving stress, called redirected aggression. Stanford physiologist Robert Sapolsky describes it this way:“Numerous psychoendocrine studies show that in a stressful or frustrating circumstance, the magnitude of the subsequent stress-response is decreased if the organism is provided with an outlet for frustration. For example, the [glucocorticoid] secretion triggered by electric shock in a rat is diminished if the rat is provided with a bar of wood to gnaw on, a running wheel, or, as one of the most effective outlets, access to another rat to bite.”
