This trial does not extend or rely on any prior RCTs.
The norms that underpin societal prejudice can be highly persistent, but using the law to grant rights to minority groups may generate changes in whether people think discrimination is socially acceptable. In this project, I will test whether the expansion of legal rights for a stigmatized minority - transgender persons in India - has an effect on discrimination in a real-stakes hiring choice. I will measure whether telling people about the expanding legal status of transgenders can improve their attitudes directly, and will also examine whether such an intervention can generate positive social spillovers: do people talk more positively about transgenders in a group discussion after hearing about transgender rights, and can this persuade others in their group to subsequently discriminate less?

Experimental Design

Experimental Design
There are two main treatment variations.

First, at the start of the main survey, participants are shown one of three different videos:
1. Control video - gives no information about transgender rights, and includes placebo information about voting rights in India
2. Messaging video - the participant is shown persuasive messaging, arguing that transgenders in India should have fundamental rights
3. Law video - the participant is shown a video that tells them that transgender people actually do have legal rights in India because of a Supreme Court ruling in 2014

In addition, participants are cross-randomised into one of two conditions:
1. Discussion - respondents take part in a discussion among a group of 3 neighbours, in which they discuss their preferred worker and make a collective hiring choice
2. No discussion - respondents do not take part in a discussion.

See pre-analysis plan for further details on the experimental design.

In phase 2 of the experiment, two additional treatment arms will be added:
1. Pairwise discussion - 2 respondents in a group take part in a discussion, and the 3rd respondent listens
2. Public choices - respondents choose while knowing that their responses will be made public to the others in their group

Randomization using an R script.

Experiment Characteristics

Sample size: planned number of clusters
Approximately 1133 groups of 3 respondents
Sample size: planned number of observations
Approximately 3400 respondents
Sample size (or number of clusters) by treatment arms
N = 300 for each of the following arms:

In total:
1. No discussion: N = 1300
2. Discussion: N = 900
3. Public choices: N = 600
4. Pairwise discussion: N = 600

Each will be cross-randomised with the information treatment, so that:
1. Control video: N = 1133
2. Messaging video: N = 1133
3. Law video: N = 1133
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Main comparison between 6 treatment groups: Each participant states their preferences over 6 pairs of delivery options. 2 of these pairs includes 1 transgender delivery worker. Based on simulations from pilot data from 120 individuals, this yields an MDE of 15 percentage points (0.3SD) on pairwise comparisons between the 6 treatment arms (assuming 𝛼 = 5%, power = 80%). Comparison of No discussion with Discussion. Similar simulations imply an MDE of 7.5 percentage points (0.15SD).
