Primary Outcomes (Explanation) They report a random draw, so I compare what they draw and what they report. They report a random draw, so I compare what they draw and what they report.
Planned Number of Clusters 120 dyads for sequential treatments and 60 for simultaneous. I assume that in simultaneous, given that participants decide without knowing what the other decided, I can use the report of both participacipants in the group as identical. So, I have two observations by dyad. 120 dyads for sequential treatments and 60 for simultaneous. I assume that in simultaneous, given that participants decide without knowing what the other has decided, I can use the report of both participants in the group as identical. Then, I will only need to collect half of the dyads compared with other treatments. There is the possibility that the second player left the game given that they can get tired of waiting for the first-mover decision. In these cases, a robot will take decisions on behalf of P2. I will not exclude these observations from the analysis, because arguably this does not change the decision because they only learn whether their partner dropped-out after making their decisions.
