Experimental Design
Experimental Design
Laboratory experiment plus MTurk experiment.

There are 9 treatment arms in a 3x3 design, combining 3 different types of messages with 2 "new products" + 1 absence of a new product. Full details in pre-analysis plan registered with OSF.
Experimental Design Details
Randomization Method
Randomization done by computer.
Randomization Unit
Individual.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
800 laboratory subjects
1,800 MTurk subjects
Sample size: planned number of observations
800 laboratory subjects 1,800 MTurk subjects
Sample size (or number of clusters) by treatment arms
200 to each of the 9 groups for MTurk
For laboratory experiment, 200 health messaging - new product 1, 100 health messaging - new product 2, 100 health messaging - no new product, 200 ethical messaging - new product 1, 100 ethical messaging - new product 2, 100 ethical messaging - no new product. The extra weight on new product 1 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)
