Yes, understand what you're saying and agree on how it works.
Let us compare a concert pianist, who's muscle memory is equisitely nuanced and, with extremely rare exceptions, not subject to lapse regardless of "surprise".
While not in the same class of training, (it's neither possible nor necessary) as a concert pianist, it is in the same category.
I do not agree and do not grant that minds and muscles go blank in a manner that is, as in the case of pianists, other than extremely rare. While all is not amenable to rational analysis or thought, the probability that a transport crew is going to lose the picture at the first sign of abnormality, is not a basis for explanation. There are too many counter-examples.
The one thing I think is reasonable to accept is, there is no training in actually dealing with surprise, fright, panic etc. I have in the past expressed two reasons for this: Training-training-training and SOPs are intended as both predictive tools for crew coordination, and preventative measures to counter surprise, fear and inappropriate responses. Demonstrably, this works. But we are, after all, humans.
What I am unwilling to broach without substantive evidence is a shift in the characterization of crew responses into another industry which sets aside the old-fashioned notion of competency and how such is achieved.
