Experimental Details

Interventions

Intervention(s)
We consider several treatment conditions that vary contextual factors which might affect persuasion using models. Using the exogenous variation provided by our treatments, we are able to examine comparative static comparisons to better understand what drives persuasion.

Further details pertaining to our experimental design are included in the attached pdf.

Primary Outcomes

Primary Outcomes (end points)
Key outcomes are described in detail in the attached pdf, but are mainly constructed from the beliefs of receivers and messages of senders.

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
Several layers of randomization are implemented by the computer software, oTree, that was used to programme this experiment.
Randomization Unit
We have multiple layers of randomization:

(i) Participants are randomized into different treatment conditions and then randomly assigned into groups of 6.
(ii) Within groups, participants are randomized into being senders and receivers.
(iii) Senders are randomized into different incentive conditions.
(iv) Sender-receiver pairs receive randomly generated data series to inform their decisions.
Was the treatment clustered?
Yes
