The first of these three things I have mentioned in this blog before. I spend a lot of time taking apart fatal aviation accidents, looking for the influences and factors which came together in the unique combination that allowed each ‘accident’ to happen. In recent years one of the most common precursors to a crash is procedural non-compliance – deviation from standard operating procedures by one or more of those involved. The reasons that pilots and other professionals deviate in this way are many and often related to complex human behavioural conditions; it is worth looking at Abraham Maslow’s hierarchy of human needs for insight into some of them. Whatever the underlying reasons, prior to a crash the captain will frequently decide to do something contrary to their training and procedures, that will eventually lead to their own demise. Sadly their co-pilots often look on, aware that all is not well but saying nothing.

The second thing is ‘risk denial’; maybe I have raised it in earlier posts. This is a condition that arises when we are regularly exposed to a particular, perhaps severe, hazard but it never actually does us any harm. Over time we may subconsciously adopt a mind-set that whilst the severity could be very high, the probability or likelihood is so low that it can be disregarded. Imagine passing a heavy truck in the opposite direction on a narrow lane – the obvious action would be to slow down and pull in to the side of the road to let it pass safely but every time you have passed a truck no harm has come of it. So you are able to ‘deny’ the risk, despite its blatancy, and drive on as normal with a metre or less between you and death.

So here is the final thing and I wonder if there is a connection between the three? Modern movies, TV shows and most significantly computer games allow us to experience horrifically dangerous and deadly situations without suffering any (other than perhaps psychological) harm. Could that have led to a general conditioning of westernised humanity (including pilots) to be able to subconsciously ignore hazards and adopt risky behaviours on the assumption that we will come to no harm however bad things look? After all, passengers now routinely collect their baggage before evacuating an aircraft, despite the high risk of fire and explosion. I don’t know…
