The Missing Half: Structured return in scenario-based training for high-stakes professions — a position paper

Abstract

Scenario-based training is standard practice wherever professionals must act under pressure: law enforcement de-escalation and crisis-intervention drills, emergency response, custodial and forensic practice, military and humanitarian preparation. Participants are placed inside constructed circumstances, repeatedly, often with professional role-players, and often across consecutive days. Training traditions in these fields give sustained attention to entry — briefing, scenario design, fidelity, immersion — because entry is what makes the exercise work. The movement out is comparatively unarticulated. It is generally assumed to occur by itself once the exercise is called. This paper argues that the asymmetry is a design gap rather than an oversight, that it is already recognised in adjacent fields under the term de-roling, and that a usable instrument exists. It sets out the shape of the problem, what a structured return does and does not claim to do, and why the risk in such exercises concentrates in the debrief rather than in the enactment. It is a position paper, not an evaluation study. No claim is made here about measured effects.
