This does actually remind me of how flight controllers were simultaneously selected and trained: the sim team designed scenarios that were specifically tailored to exercise some controller's weak point, over and over. They were very creative in how to exploit controllers' weaknesses.

Some controllers took their simulator failures as serious lessons and improved. Others didn't stomach the constant failures and dropped out of the programme. I don't know what proportion of alpha chicken they got, but from what I can tell, the flight controllers were really good at their jobs.

I've always wanted to explore adversarial simulation as a training and selection method but I have yet to find an occsassion that warrants it.
