Detailed replication evidence · 2026-11-02
Right direction on all 7 significant effects, close ranking (ρ = 0.99); sizes not comparable (the paper reports logit coefficients).
Use it to screen and rank which attributes move choice; sizes need the paper's respondent data.
- direction
- holds
- rank
- holds
- size
- not comparable
Supported uses
- Screening which attributes move choice, and in which direction.
- Ranking attributes and levels by how strongly they move choice.
Limits to keep in view
- 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 = 3.1575. Calibration aligns magnitude; it does not establish agreement in unadjusted effect sizes.

| Protection rate prevented by vaccines: 65% (reference) | 0.000 | Not measured | 0.000 |
| Protection rate prevented by vaccines: 80% | 0.504 | Not measured | 0.433 |
| Protection rate prevented by vaccines: 95% | 1.230 | Not measured | 0.773 |
| The risk of severe side effects: High risk (reference) | 0.000 | Not measured | 0.000 |
| The risk of severe side effects: Moderate risk | 0.793 | Not measured | 1.083 |

| Location of vaccine manufacturer: Domestic (reference) | 0.000 | Not measured | 0.000 |

Subgroups · screen, not a result
Split by education: 1 of 2 significant differences keep their direction in the simulation (9% to 91%)
screen, not a result. Each row is the college and above group’s effect minus the below college 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.
