Experimental Design

Experimental Design
We exogenously vary contextual factors that may play a role in influencing persuasion using narratives.
Experimental Design Details
Please refer to the attached pdf for details.
Randomization Method
The randomization is implemented by the computer software, oTree, that was used to programme this experiment.
Randomization Unit
We have multiple layers or randomization. These are described in detail in our attached pdf.

Our main between-individual randomization will be done at the individual level. Within each pair of treatments, individuals have an equal (50%) chance of being randomized into each treatment condition.

In addition, we add exogenous variation in the individual rounds that an individual completes. Much of this is similar to the randomization described in detail in our working paper https://www.cesifo.org/DocDL/cesifo1_wp10206.pdf. The attached pdf in this pre-registration provides details.
Was the treatment clustered?
Yes
