Before
Subjects make multiple choices between an ambiguous option (for which the probability of winning a prize is unknown) and an uncertain option (for which the probability of winning a prize is known). For each subject and prize level we vary the attractiveness of the uncertain option while keeping the ambiguous option fixed.
We will run two robustness checks of the main design. One will have exactly the same design but will use a pool of workers with Amazon's "Masters" qualification. The other will present the same choices as the main design, but in a different layout/format.

Update on May 22, 2023: We will run a third robustness check in which the same prize is offered three times (i.e., instead of varying the prize).
