Randomization Method
Randomization done by computer.
Randomization Unit

No

Experiment Characteristics

Sample size: planned number of clusters
600 laboratory subjects
1,200 MTurk subjects
Sample size: planned number of observations
600 laboratory subjects 1,200 MTurk subjects
Sample size (or number of clusters) by treatment arms
200 to each of the 6 groups for MTurk
For laboratory experiment, 200 health messaging - new product 1, 100 health messaging - new product 2, 200 ethical messaging - new product 1, 100 ethical messaging - new product 2. This is to allow for a further subdivision amongst those who receive information about new product 1 for a separate paper (which will have its own pre-registration and pre-analysis plan).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
