The certificates on the wall may be making people slower Every newly learned technique, every newly earned certificate, gives the impression of a margin of safety: a repertoire acquired so that it will be there if needed one day. But the way the human decision-making mechanism actually works reverses this intuition directly: the larger the repertoire grows, the longer it takes to access it. The claim of this article is simple and may be uncomfortable to hear: having thirty di

1. Introduction Volume I addressed the visual-motor (Vickers's feed-forward model) and cognitive (Klein's Recognition-Primed Decision model) foundations of target transition in dynamic shooting sports, showing that these mechanisms operate reliably within the sporting context. That volume closed on an unresolved question: do these mechanisms remain intact under the perceptual narrowing reported under genuine threat (tunnel vision, auditory suppression, an autopilot response),

1. Introduction In dynamic shooting sports (IDPA, IPSC, Multi-Gun), target transition and multiple-target engagement are taught largely as a skill domain grounded in coaching experience and orally transmitted practical knowledge. "Predictive shooting" the shooter acting on knowledge of technique and equipment rather than waiting for explicit visual confirmation from the sights before every shot (Stoeger & Park, 2021) is one of the central concepts in this domain. However, thi
