A, Eleven choice sets in the experiment, with dots representing bundles (options) and lines representing choice sets (trials). The red line shows the example presented in Figure 1. B, One example of choices that violate GARP from a simulated participant. The selected bundle A is directly revealed preferred to all other bundles on the red solid line including bundle B. By monotonicity, bundle B is objectively better than the corresponding bundle on the blue dashed line (bundle C). By transitivity, bundle A is preferred to bundle C. However, the simulated participant in our example selected bundle C (blue dot), a choice that violates GARP.
