Abstract
This project examines an environment where a group of two senders (group-members) communicates with a receiver (evaluator) by disclosing or not disclosing a realized outcome. Group members have distinct preferences over the group's disclosure decision, and their disclosure recommendations get aggregated into a disclosure decision according to a deliberation protocol. We characterize, both theoretically and experimentally, the relation between a group's deliberation protocol and two observable outcomes: individual disclosure recommendations, and the evaluator's interpretation of the absence of disclosure. Generally, the evaluator interprets ``no news'' with skepticism, but each of the group-members is more or less targeted by that skepticism depending on how the group deliberates.

Randomization Method
Subjects voluntarily sign up to participate in our sessions after receiving an invitation email. We then randomly assign each session to one of the treatments.
Randomization Unit
In our study, the randomization unit is individual.
Was the treatment clustered?
No
