Intragroup Peer Discussion for Outgroup Discrimination Reduction
RCTReview
Intergroup contact interventions reduce prejudice but are difficult to scale because individuals predominantly interact within their own identity groups. Labor market discrimination against transgender workers persists due to social coordination barriers and unobserved group norms.
Picture this
Think of a group of drivers waiting at an intersection where everyone secretly wants to let a merging car pass, but nobody moves because they assume other drivers will get angry. When three people sit together and talk about traffic courtesy for ten minutes, the driver who cares most speaks up first, realizing others actually agree. Once the unwritten rule is spoken aloud, everyone changes how they drive because they now know the rest of the group approves.
What the evidence says
3-person group discussions increased selection of transgender delivery workers by 17 percentage points (a 42% increase over control), while 2-person discussions increased selection by 13 percentage points. 25% of the short-term impact persisted after 2–9 weeks (4 percentage points or an 11% increase over control), whereas public non-discussion produced no significant change.
- Who was studied
- 3,397 non-transgender participants in urban Chennai, India.
- How
- Randomized controlled trial framed as market research for a grocery delivery service; participants made 10 private binary hiring choices between cisgender and transgender workers, assigned to 3-person discussions, 2-person discussions, public decisions without discussion, or private individual control groups, with a follow-up survey averaging 35 days later.
What to do
Organize structured 10-minute peer discussions among majority-group hiring managers prior to candidate selection to activate latent consensus around non-discrimination.
From the source
"Compared to individuals in the comparison group that did not take part in group discussions, participants in 3-person discussions (group one) were 17 percentage points more likely to select a transgender individual for their delivery (a 42 percent increase)."
