  "title": "Use a smile, nod or greeting as a low-cost social acknowledgment",
  "summary": "Connection has smaller units than conversation.",
  "kind": "protocol",
  "body": "Offer a brief culturally appropriate acknowledgment—eye contact, smile, nod or greeting—when the context feels safe and receptive. Let it end there unless the other person reciprocates. These small signals can communicate openness without demanding time or disclosure.",
  "limits": [
    "Social norms vary by culture, safety and context; respect non-response and personal space."

    {
      "claim": "In a nationally representative English sample, a visible 'Happy to Chat' badge increased perceptions of friendliness, trustworthiness and openness to conversation and increased intentions for small social acknowledgments.",

      "role": "supports",
      "note": "The study used pictured targets and stated intentions rather than observed public interactions.",

    {
      "claim": "The stranger-listening studies found global listening quality was associated with connection markers even in brief small-talk interactions.",

      "role": "supports",
      "note": "Global behavioral coding is broader than one simple behavior such as question count.",

  "use_when": [
    "A full conversation feels inappropriate or too demanding but you want to be less socially invisible in routine public life."
  ],
  "avoid_when": [
    "Social norms vary by culture, safety and context; respect non-response and personal space."
  ],
  "example": "Say hello to the neighbor in the lift and let the exchange remain one sentence if that is where it naturally stops.",
  "check": "You create small opportunities for mutual recognition without turning every encounter into a conversation goal.",
  "steps": [
    "The setting is safe and casual, and brief acknowledgment is normal.: Offer a small signal and allow it to end naturally.",
    "The person appears busy, uncomfortable or unreceptive.: Respect the cue and do not escalate the interaction."
