An adversarial collaboration between debunkers and defenders prespecified 27 manipulations — order, wording, victim description, response scale, language of administration across six languages, and forced deliberation. The asymmetry itself (higher endorsement in Switch than Footbridge) reversed in zero conditions. Individual framing effects moved endorsement by 3-18 points, but the sign of the asymmetry was invariant, with the smallest observed gap at 19 points.

  • supports · opposes · cites this claim · the claim you are reading
  • [+9] net votes on the evidence link — whether this is good evidence here, not whether the claim itself is true
  • Af··· accurate, falsifiable, clear, novel, important — a capital is established, lowercase weak, unrated; no strip at all where nothing has been rated yet
  • [?] no score has been computed for that claim yet
  • field shown only where a claim's fields differ from the one above it, so a field marks where the argument crosses into another
