In Simple Words
Watching a broadcast announcement about a new law is like getting a temporary flyer on a windshield; it reminds people of the rules for a day, but gets thrown away and forgotten. Engaging in a live conversation with peers is like building a communal sign together; because participants actively argue and internalize the message with people they know, the shift in belief remains standing long after the meeting ends.

Immediate private choices; videos crossed discussion assignments. No clear video effect remained around one month later; follow-up choices were hypothetical.

Top-down information campaigns broadcasting legal rights can generate immediate compliance or behavior shifts, but often lack long-term retention. Policy makers need interventions that sustain bias reduction beyond initial exposure.
Participants
3,397 non-transgender individuals in Chennai, India, with subset groups assigned to video treatment arms (1,135 legal rights video, 1,135 rights messaging video, 1,135 comparison video).
Study Design
Randomized experiment comparing 2-minute video screenings (Supreme Court legal rights vs generic rights messaging vs control) against group discussion treatments, measuring private hiring decisions immediately post-treatment and approximately 35 days later (2–9 weeks).
Results
Viewing legal rights videos initially increased transgender worker selection by 10.3 percentage points (a 23% increase), and generic rights messaging increased selection by 5.8 percentage points (a 13% increase). However, approximately one month after the intervention, behavioral impacts from video screenings decayed completely to zero, whereas peer group discussion impacts persisted significantly at 4 percentage points.
Takeaway
Replace passive legal rights video broadcasts with interactive peer-group dialogue modules in compliance training programs to ensure behavioral persistence beyond one month.
