Vicarious Deliberation Spillover in Passive Listeners
RCTReview
Group deliberation interventions often assume active verbal engagement is mandatory for individual norm revision, raising questions about whether passive observers gain meaningful behavioral shifts from listening to peer discussions.
Picture this
Imagine three colleagues sitting at a table where two people debate a topic while the third silently listens. Even though the listener never opens their mouth, hearing their peers express fair-minded arguments changes their understanding of what the group considers acceptable, leading them to adjust their future behavior accordingly.
What the evidence says
Passive listeners in the 2-person discussion arm increased their selection of transgender workers by 13 percentage points relative to control, capturing roughly 76% of the 17 percentage point gain observed in fully active 3-person discussions.
- Who was studied
- 549 non-transgender participants assigned to the 2-person discussion arm (out of 3,397 total participants) in urban Chennai, India.
- How
- Randomized experiment comparing active 3-person discussion groups against a 2-person discussion structure where two individuals discussed hiring choices while a third participant listened passively.
What to do
Include passive audience observers in structured peer deliberation sessions when logistical or time constraints prevent every individual from speaking actively.
