Following the video on Zero Harm Rob discusses the ideology of zero embedded in the Bradley Curve and logic of the Bird and Heinrich Pyramid. Rob draws attention to the religious nature of the Bradley curve and its use of religious language to explain 'natural instincts' of humans to be naturally unsafe. The ideology and assumptions of the Bradley Curve make disturbing assumptions about what it is to be human. Indeed, the whole zero harm ideology takes on a fundamentalist quest for perfection on rivaled by a religious quest. The video concludes with a brief discussion on the construct of the pyramid concocted by an insurance salesman in the 1930s without any validation, now used by the risk and safety industries to justify zero and the establishment of intolerant regimes of zero fixated on counting injury statistics as a demonstration of safety. The idea of demonstrating the the evidence of something by the absence of something else is shown to be erroneous and a contributor to toxic organisational culture.
