Detailed replication evidence · 2026-11-04
Right direction on 6 of 8 significant effects, partial ranking (ρ = 0.74); sizes not comparable (the paper reports logit coefficients).
Use it to screen which attributes move choice; sizes need the paper's respondent data, and confirm the 2 reversed effects with people.
- direction
- mixed
- rank
- mixed
- size
- not comparable
Supported uses
- Nothing yet without human confirmation.
Limits to keep in view
- Ranking close levels against each other; the order diverges from humans.
- Decisions that hinge on the attributes whose direction flipped (listed below).
- Effect sizes in the paper's units; only direction, rank and shape are compared.
Effects on a common scale
Human effects: logit coefficient. Synthetic effects are multiplied by the record’s calibration factor, k = 2.0729. Calibration aligns magnitude; it does not establish agreement in unadjusted effect sizes.

Subgroups · screen, not a result
Split by sex: no significant difference between the groups, so there is nothing to compare
screen, not a result. Each row is the male group’s effect minus the female group’s, human in logit, simulated on the simulation’s own scale, so compare direction, not size. A Jev fast-small screen makes no comparison claim.
