  "title": "Practice recoverable errors when transfer matters",
  "summary": "If the real job includes recovery, flawless rehearsal can leave the recovery skill untrained.",
  "kind": "protocol",
  "body": "Create a safe practice case where a wrong move is cheap and reversible. Attempt it before the full solution is shown, inspect the mismatch, correct it, then try a changed case that requires the same underlying judgment. The useful target is exploration plus diagnosis and recovery—not collecting mistakes for their own sake. Error-management research is strongest on transfer, but later experiments also show that simply telling people to make or welcome errors is not a universal advantage.",
  "limits": [
    "Do not manufacture errors in production or other high-stakes environments. Beginners who lack prerequisite knowledge may need more scaffolding, and exact routine procedures may benefit more from error prevention. The evidence supports a bounded training design, not a rule that more mistakes mean more learning."

    {
      "claim": "A meta-analysis of 24 error-management-training studies (N=2,183) found a positive average effect (d=0.44), with larger effects for post-training transfer (d=0.56) and structurally different adaptive-transfer tasks (d=0.80) than for performance during training or more similar tasks.",
      "role": "supports",
      "note": "The synthesis is from 2008, effects varied substantially, and the estimates do not show that deliberately increasing error rate is universally beneficial.",

      "claim": "In a randomized experiment with 164 participants where active exploration and task information were controlled, error encouragement produced better transfer than error avoidance but was not better than a no-error-instruction control.",

      "note": "The simulated air-traffic-control task and observed individual-difference interactions limit broad generalization; the result specifically weakens a simple claim that encouragement to err is the active ingredient.",

    "You are learning a tool, diagnosis or workflow in a sandbox and the real skill includes handling unfamiliar cases, not just repeating one exact procedure."

  "example": "In a training SAP tenant, diagnose a seeded configuration-versus-data mismatch without a click-by-click guide. After correcting it, solve a second incident with different symptoms but the same underlying dependency. Do not seed defects in a live client system.",

  "steps": [
    "Isolate the practice: use a sandbox, simulation, disposable copy or otherwise reversible environment.",
    "Set a stop rule before exploration so a mistake cannot cross into production, safety, security, privacy or irreversible loss.",
    "Attempt the case with enough guidance to understand the task but without revealing every step.",
    "When an error appears, name what you expected, what happened and which cue or rule you missed.",
    "Correct it, then retry on a variant that changes surface details and keeps the underlying decision.",
    "Judge the method by delayed or transfer performance, not by how many errors the practice produced."
