From the Defence Aviation Safety Centre Journal 2008, the article "Military Human Factors--Where We Are Now, Where We Might Go" explains why problem solving needs to go beyond simply blaming an individual as the source or cause of a problem:
The search for causes tends to stop when we can find the human or group closest to the accident who could have acted differently...that would have led to a different outcome. These people are seen as the source or 'cause' of the failure.
...we react, after the fact, as if the knowledge we now possess was available to the operators then. This oversimplifies or trivializes the situation confronting the practitioners and masks the processes affecting practitioner behaviour before the fact. As a result, hindsight and outcome bias blocks our ability to see the deeper story of systematic failures that predictably shape human performance.
