The probabilistic behaviors of power system failures are the root origin of risks [1], and an effective risk assessment model can provide quantitative risk indices to represent system reliability.
But it is also a problem when studies like the work of Egan and Mullin distract us from what the research tells us are the real roots of this Risk Perception Gap, a gap between our fears and the facts that poses danger all by itself.
In the Chair's summary of the GP of 2013 emphasis was placed on targeting the root causes of risk where participants raised the need to take concrete measures to tackle risk drivers including baseline levels of disease, inadequate health services and infrastructure before, during and after disaster events, and poor water and sanitation (GPDRR 2013).
