This is incorrect, as far as the research into training for expertise goes. You actually want simulations to be like the real world: complex, ambiguous, sometimes with delayed feedback and presenting multiple forms of the problem. Of course, it also takes a good mentor to debrief with and untangle what was bad luck and what was bad decision making. (See the Oxford Handbook of Expertise if this stuff interests you.)
