  "title": "Require an active choice when no safe default fits most people",
  "summary": "A default is convenient only when choosing for people by inaction is defensible.",
  "kind": "principle",
  "body": "If reasonable people may want materially different outcomes and you cannot justify one preset as a safe fit, require a small explicit choice instead. Keep the alternatives understandable and proportionate to the stakes. If you do use a default, say what is preselected and make changing it practical; current transparency evidence does not support the assumption that disclosure necessarily destroys the behavioral effect.",
  "limits": [
    "Active choice has its own attention cost and can be harmful when users lack information or the decision is needlessly complex. Do not remove well-justified safety defaults merely to appear neutral, and do not use transparency as permission for manipulative friction."

    {
      "claim": "A review of default-nudge design argues that active choosing can reduce some autonomy and welfare problems created by inappropriate defaults, especially when a choice architect cannot safely presume one option fits the chooser.",
      "role": "supports",
      "note": "Active choice also imposes attention and decision costs; it is not automatically better for simple, low-risk or strongly preference-aligned decisions.",

    {
      "claim": "A 2025 meta-analysis comparing transparent with covert nudges found no evidence that transparency generally weakens behavioral outcomes and reported a positive pooled transparency effect on behavior, but the evidence was dominated by online or laboratory default studies.",
      "role": "supports",
      "note": "Only two included studies were field studies and 88% of effects involved defaults, which sharply limits generalization to other nudge types and real-world settings.",

  "example": "Instead of silently enrolling every teammate in a high-notification mode, ask once between focused and high-alert modes when both are legitimate working preferences, then let the person change it later.",
  "check": "The design can explain why a default is appropriate—or it replaces the preset with an explicit choice when that justification fails.",
  "checklist": [
    "Would different reasonable users want different outcomes here?",
    "Can the preset create meaningful cost, privacy, risk or commitment for somebody who overlooks it?",
    "Can I justify one default from the chooser's interests rather than my convenience?",
    "If not, can I ask for one clear explicit choice?",
    "If a default remains, is it visible and easy to change?"
