Mitigating risk is achieved through deeply understanding the problem space, and putting in the training to demonstrate ability to operate within the workspace.

Stupidity is blundering in without understanding the space. Ex “local man who has never climbed before takes up free climbing” is stupid.
NASA absolutely pared down safety “wants” left and right, they pioneered the technical risk analysis methods that resulted in the successes (and failures) of that program. It’s a fascinating read if you’re curious
