says that what people do makes sense to them at the time—given their goals, attentional focus and knowledge—otherwise they wouldn’t be doing it. In other words: people do not come to work to do a bad job. Pilots do not check in for a flight in order to die. Nurses do not sign in to go kill a patient (and if they do, it takes you into the realm of sabotage, criminality, terrorism which requires different explanations and interventions—not part of this book).
