Human beings are very bad at diagnosing failures in complex systems when under intense pressure. Perception and cognition can be significantly affected and even normally highly competent and trained individuals can make poor decisions at times of high stress. I’m not qualified to judge how much of this was down to pilot error, but the risk is ascribing it purely to this and moving on takes away emphasis from redesigning the system to give the flawed human beings piloting the plane the best chance of making the right decision next time.
