This chapter describes the world as black or white and uses that as the basis of explanations and communication. A strategy of depth-before-breadth makes it possible to pursue a single idea until the objective has been achieved, while at the same time limiting the mental effort required. The main issue with safety – and the reason why it is an ever-growing problem – is that the lack of safety is neither due to a single factor, nor can it be comprehended by a single view. A contemporary approach to safety should recognise that; it should try to embrace multiple perspectives in a comprehensible way. Since the focus of safety is on the negative, on what goes wrong or fails, the efforts focus on how to eliminate the causes. New perspectives and new approaches are brought on to solve the old problems, but the problems are understood in the same way, at times with a sprinkle of complexity added.
