Overreaction and overregulation are usually the work of people within bureaucratic structures who have developed a mindset commonly known as CYA (Cover Your Ass). They know they can be held responsible for any problem that arises on their watch, especially if they took no action to prevent it, so they often adopt a defensive stance. In their minds, overreacting is better than underreacting, overregulating is better than underregulating, and caution is better than courage. This attitude reinforces the safetyism mindset that many students learn in childhood.
