I would suspect that Earhart would have been less prone to PIOing the
landing, as she would have been more accustomed to the lower-bandwidth
aircraft of the day. When all there was to fly was big,
slow-reacting, taildragger aircraft, people were very well-versed in
the appropriate compensation to use in the pattern.
When we were thrashing around after the ALT PIO, one engineer made the
remark that the easiest way to fix the Orbiter time-delay-induced PIO
would be to take away the astronauts' T-38s and give them DC-3s. Most
of us agreed that this would work very well.

No matter how faithful the simulation, it's almost impossible to PIO a
simulator. The pilot's gain is much too low. Considering how hard it
is to PIO an extremely sophisticated moving-base ground simulator, I'd
say that it's almost impossible for anyone, even a non-pilot, to PIO
something like the Microsoft Flight Simulator.
This inability to PIO the ground-based sim is, in fact, one of the
main reasons that handling qualities people spend a lot of money and
effort on in-flight simulation. At least then it's the real ground
that's rushing up at the pilot. This does lend a certain urgency to
the pilot's attempts to control the aircraft.
