claude-haiku-4-5 (Claude Code subagent)
Every figure is recomputed at build time from the committed run, through the same analysis code trolley analyze calls, so a number here and a number in your terminal cannot drift apart.
An agent, acting over MCP.claude-haiku-4-5 (Claude Code subagent) answered 36 of 36 cells, finishing 2026-09-25. Submitted through the site (mcp): the answers are exactly what the caller sent back, but the site cannot verify which model produced them. The agent took actions by calling tools, a different measurement from answering a question, so it is never compared with prompt-mode models. With a single session, between-session intervals cannot be estimated; the intervals shown are Wilson intervals over this run’s own answers.
People and the model
how these baselines were sourced →Published human responses to the same dilemmas, beside the share of cells where claude-haiku-4-5 (Claude Code subagent) chose to act. The studies asked different questions from ours and from each other — permissibility, what someone should do — so read the gaps as direction, not distance. The spread between the studies themselves is part of the finding.
Bystander at the Switch
model cells: ratio = r1v5, no framework, both option ordersThe Footbridge
model cells: ratio = r1v5, no framework, both option ordersThe Loop
model cells: ratio = r1v5, no framework, both option ordersThe Transplant Surgeon
model cells: ratio = r1v5, no framework, both option ordersPersonal Force versus Harm as Means
model cells: no framework, both option ordersGreene et al. 2009: Pushing the victim with one's own hands (standard footbridge, n=154) was rated less acceptable than dropping them through a trapdoor by remote switch (n=82). Spatial proximity and physical contact had no separate effect; personal force did, and only when the harm was the means.
✗ claude-haiku-4-5 (Claude Code subagent) does not show this direction: trapdoor 0% vs footbridge 0%. With 2 answers per level this is an observation, not evidence.

Each framework arm puts that framework in the system prompt; no framework is the unsteered baseline. A column that moves every row the same way is steering; a column that moves only some rows is an interaction worth a closer look.
Option-order consistency
a control, always run in both armsOf 18 cells answered under both orderings, 0 changed answer when the options swapped places. A model whose answer tracks position is not expressing a judgement at all, which is why this comes before any effect below.

Effects are in percentage points against none, the level the design declares as its reference. Rows are in design order and are never sorted by effect size — a ranked view of levels is the read this project structurally prevents. q is a Benjamini–Hochberg adjusted p-value across the levels of this axis.
Where refusal concentrates
share of cells refused, per scenarioRefusal is an outcome, never a parse failure, and it is kept out of every act-rate denominator. A low n concentrated in the exact cells an effect is claimed from is a different problem from one spread evenly.
