vilas, from a previous post 'Humans are fallible, we will suffer error, but if we cannot imagine this - that we won't make mistake, whatever the training - then inappropriate conclusions can focus on solutions involving even more knowledge and training - blame.
It is a misguided belief that we can prevent all accidents or that we can foresee every eventuality, however improbable.'
We cannot foresee every safety event. Any contradicting argument must explain why we did not foresee this accident and have training in place.
Hindsight is a very powerful bias, and more often the least effective safety solution.
