Debiasing mechanism
The argument
Because safety cases are prone to confirmation bias toward a predetermined conclusion of safety, positive safety arguments tend to leave disconfirming considerations unexamined; and because deliberately considering reasons a favored conclusion could be wrong reduces confirmation bias and overconfidence, a systematic search for defeaters directs attention to exactly the weaknesses that one-sided argumentation overlooks.

The inference goes through: if positive safety arguments systematically under-attend to disconfirming considerations and directed doubt corrects that tendency, a structured defeater search will surface some of what was overlooked. Its weight rests on the effectiveness of deliberately considering how a favored conclusion could be wrong, which is not yet assessed here but reflects a well-replicated debiasing literature; the confirmation-bias tendency of safety cases stands supported. The argument establishes that the search finds something overlooked, not that it finds everything that matters.
