Randomization procedure: 
The treatment group and the control group read different vignettes.
Study 1 conducted the “reducing response substitution” experiments using eight information treatments. Study 3 applied this strategy to one additional treatment. Using the same eight treatments, Study 1 also evaluated the counterfactual format using the same strategies described above. Study 2 applied these strategies to two additional treatments. Table 2 summarizes all 11 treatments and their corresponding outcome variables.
