The absence of feedback on primary controls seems to be such an error.
Then bring your evidence, as has been asked many times by many people - because right now there doesn't seem to be any.
As a touch-typist and guitarist I'm well aware of how much I rely on muscle memory - surely it must be similar with pilots?
You just brought the answer to your own question. Try to type in a stress environment at the same speed in an AZERTY keyboard than the one you can do on a QWERTY keyboard and see the difference for yourself...
You would have to use your yes and concentration on what you are really typing in order not to commit mistakes. The same for the pilot, that doesn't have the feed-back on the stick. He his deprived from his tactile feed-back and has to look at the PFD to see the results of his commands, therefore loosing a precious useful tool...
