Prior work
This trial does not extend or rely on any prior RCTs.
We run an incentivized representative survey in the US. In the survey we elicit individual thresholds for switching from one decision to another decision. Eliciting covariates on attitudes and personality traits allows us to test and estimate our model to predict individual thresholds.

Primary Outcomes

Primary Outcomes (end points)
The thresholds participants report. Participants enter two thresholds, one broad one and one for a more narrow reference group.
Primary Outcomes (explanation)
we do not have to construct this variable, we directly elicit it.

Secondary Outcomes

Secondary Outcomes (end points)
we elicit many covariates. The hypothesis section of this preregistration document lists them one by one.

Experiment Characteristics

Sample size: planned number of clusters
4000 individuals in the U.S.. Sample is stratified: 500 observations for each of the 8 groups (male, female) X (asian,black,hispanic,white).
Sample size: planned number of observations
Sample size (or number of clusters) by treatment arms
500 individuals in each of the eight groups. Male Asian; Female Asian; Male Black; Female Black; Male Hispanic; Female Hispanic; Male White; Female White.
Individuals in each group are U.S. representative for each of the groups on the following dimensions: Age, Region in U.S., Education. 50% of participants are in the DefaultPro treatment, the other 50% in the DefaultAnti treatment. 80% are in the Public treatment, 20% in the Private treatment. 33% are in each of the three reference group treatments.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
