Apologise for my ignorance however something occurs to me.
To draw a simplistic parallel many pilots today do not practice spins during their PPL because the FAA etc discovered that more planes were being lost in practicing than in inadvertant spins during regular flight and though we all practice developed stalls most of our time is spent diagnosing initial stall and preventing it's development.
When Airbus pilots practice stalls in the Simulator do they actually practice fully developed stalls? ie, all the way to less than 60 knots and where the stall warning turns off or just to the point of stall warning and then lower the nose and recover. If that were the case it is relatively easy to imagine that when the PF lowered the nose and the alarm sounded his reaction would be to raise it again, hear the alarm suspended and conclude that lowering the nose was dangerous.
