You wouldn’t be retrained to ignore cues from your senses and trust your instruments. That training happens when you’re young and getting your IFR ticket.
I'm just pointing out that "they just need to be trained for the plane's behavior" isn't on the table for the MAX-8. The contracts said it would have the same type rating, and therefore the MCAS, for better or for worse.
I'm not quite sure how that is related to beginner flight lessons. (?)
