Fascinating article about a Gulfstream crash and the succession of seemingly unbelievable pilot errors preceding it. But these errors make sense in a culture where failing to follow correct procedures has been normalized:
Social normalization of deviance means that people within the organization become so much accustomed to a deviant behavior that they don’t consider it as deviant, despite the fact that they far exceed their own rules for the elementary safety. People grow more accustomed to the deviant behavior the more it occurs. To people outside of the organization, the activities seem deviant; however, people within the organization do not recognize the deviance because it is seen as a normal occurrence. In hindsight, people within the organization realize that their seemingly normal behavior was deviant.
