People will always make mistakes, this can be referred to as human error, or the human factor. The goal of the study of human error is to attempt to prevent its occurrence, avoid recurrence or mitigate the effects of both.
Maintaining a perfect awareness of the whole situation is impossible, and in some reports it proved an easy way to target and blame individuals. We should not stop seeking to improve our personal qualities, but we need to understand the limitations of our abilities to “train out” undesirable characteristics. Persisting with a blame culture inhibits improvements which could genuinely reduce the chances of human error, by focussing on the individuals rather than the system.
