The Switch/Footbridge asymmetry survives every framing manipulation tested in a 27-manipulation adversarial protocol (Ferreiro & Adeyemi, 2023, N=19,400)

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.

Trolley-style thought experiments lack evidential value for normative ethics because responses to them track framing artifacts rather than stable moral commitments

The 19-point minimum asymmetry gap exceeds the largest single framing effect (1…
Converts the defense from 'the asymmetry is robust' to a quantitative bound: the artifact literature's own largest effect cannot manufacture the phenomenon. The obvious attack is additivity — several artifacts stacking could exceed 19 points even if none does alone.
