I agree that Humans inherently get things wrong and learn from them, however I don’t like your seemingly blasé attitude towards it. ‘Getting things wrong’ in aviation can and has on many occasions, prove fatal. Being taught the correct way of doing things first time round, and noting when problems might arise is how tragedies can be avoided. You seem to be suggesting that getting something wrong and mitigating is an appropriate method of learning; I however think that at the very latest problems should be trapped before mitigation is necessary. Even during the learning process. And the experience you talk about comes about from trapping problems and in future you can avoid the same problems before they even develop.
I really don’t think ground school questions can be related, you can simply put down the book and think about it. In the air it is far far different. Im sure you can appreciate.
