Leadership is a skill. We train it like one.

Fitts & Posner described three phases — a cognitive stage of explicit rules, an associative stage of refinement, and an autonomous stage where the skill runs without conscious effort. Dreyfus traced the same arc from novice to expert.

Difficulty is matched to the stage. Guided mode pairs a stylised partner with rigid, by-the-book scoring so a beginner can learn the moves cleanly. Standard and Challenging hand over a realistic, unpredictable partner once the fundamentals are fluent.

Ericsson’s research on expert performance found the differentiator is deliberate practice: effortful, well-defined tasks just beyond current skill, repeated with immediate, specific feedback — not mere experience.

Every turn is a rep at the edge of the conversation. Feedback arrives immediately and points at the exact line you said. Mechanically repeating a move that has stopped working earns nothing — variety and intent are rewarded.

Hattie & Timperley showed effective feedback resolves three questions — where am I going, how am I doing, where to next. Black & Wiliam and Shute found formative feedback, given while there is still time to act, drives the biggest gains.

You get formative feedback on every turn — what landed, why, and a better line to try — and a summative debrief at the end. The live read keeps you adjusting; the debrief turns the whole session into patterns.

Vygotsky’s zone of proximal development and Bruner’s scaffolding describe learning at the edge of ability with fading support. Cognitive load theory adds that beginners learn more when extraneous load is removed first.

Difficulty is the scaffold. Guided mode lowers the load with a legible partner and clear rules; the support fades as you climb; in-the-moment suggestions are scaffolds you can lean on and then let go.

Kolb’s experiential cycle moves from concrete experience to reflection to conceptualisation to active experimentation. Schön’s reflective practitioner and simulation research show structured debriefs are where doing turns into understanding.

You practise a real exchange, then a structured debrief turns the transcript into named moves and clear next steps — which you carry straight into the next rep. The loop, not the single try, is the unit of learning.

Dweck’s growth mindset, self-determination theory’s focus on competence and autonomy, and Edmondson’s psychological safety all converge: people improve when failure is safe and feedback targets the work, not the worth of the person.

It’s a private sandbox built for failing well. Scoring is calibrated to encourage — an earnest attempt is never punished, only moves that work against the principle are — and feedback always addresses the line, not you.

Situated-learning research shows skills transfer when practice shares the texture of the real context. Performing to an artificial yardstick instead produces brittle, mechanical habits that don’t survive contact with a real person.

Your partner behaves like a real person — guarded, inconsistent, human — especially as difficulty rises. And the score rewards the genuine effect on them, not the words you used, so what you practise is what transfers.
