@patrickcmiller "caused" should probably be "contributed to." Also, for a study that claims to be about "human factors", there's a remarkable lack of introspection about the actual underlying human factors beyond "blame the human operator." No serious industry portraying itself as safety/security-focused would ever accept a double-digit percentage of human error resulting in significant negative consequences without a deeper examination and direct addressing of the underlying causes. We collectively need to stop blaming our users.
