You can even make the same error twice but you better have much better explanation the second time around than you had the first time around because you already knew that what you did was risky and or failure prone.
But usually it isn't the same person making the same mistake, usually it is someone else making the same mistake and nobody thought of updating processes/documentation to the point that the error would have been caught in time. Maybe they'll fix that after the second time ;)

Yes. AAR process in the army was good at this up to the field grade level, but got hairy on G/J level staffs. I preferred being S-6 to G-6 for that reason.
-You don't hide anything
-Errors will be made
-After training/mission everyone talks about the errors (or potential ones) and how to prevent them
-You don't make the same error twice
Being afraid to make errors and learn from them creates a culture of hiding, a culture of denial and especially being afraid to take responsibility.
