How many times has your instructor said "Ah, I'm glad you did that"
when you screwed up. I believe that approach to error compensation
will help keep us alive as well as welcome more people to the sport.

From the article:

"Jim Reason: Oh yes, even the best ones have bad days. It's really
quite hard to be good all the time, but yes, one of the things that
perhaps is lacking in surgical training is the mentor who hopes that
you'll make a mistake across the table, and say, 'Ah, I'm glad
you did that; now I can tell you how to fix it'. In other words, to
watch people make errors, then to teach them how to repair, to
compensate. People who will tell you the ways of error."
