The performance failure is the one to watch, because it feels like following the instructions.
Intent has a smell, as Voss puts it. Deliver a label like a checkbox, and they receive it like a checkbox. Now they know you are running a technique on them. The tools work only as extensions of genuine curiosity, the one input you cannot fake on a deadline.
The other thing to respect is the ceiling. Voss puts hostage negotiation at 93 percent and is blunt that the last seven are unreachable however long you spend. That is a claim about process, not outcomes. It sits next to Annie Duke's thinking in bets. Losing the hand with the best available process is not evidence the process was wrong.
Even inside Voss's own firm, instructors contest the sequencing. In this session, a Black Swan instructor says nine times out of ten he would reach for a label. Voss would reach for a calibrated question. Both are right. The order can change. The confirmation you drive toward cannot.
