Primary Outcomes

Primary Outcomes (end points)
The primary outcome is an index of sensitive attitudes.
Primary Outcomes (explanation)
I ask participants to state their level of agreement with 10 sensitive statements. I then aggregate the statements into an equally weighted index, making sure that all statements are oriented in such a way that larger numbers correspond to views that are perceived to be more socially acceptable.

Secondary Outcomes

Secondary Outcomes (end points)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
I filled out the "Experimental Design (Hidden)" category. I will make that category available after the end of the experiment.
Experimental Design Details
Half of the participants will be assigned to a Private Treatment and will be shown the following screen:

IMPORTANT: We will share aggregate-level answers to the questionnaire on the next screen with approximately 200 UCSD students who are scheduled to participate in the next phase of the study but no-one, not even the research team, will match your individual answers to any information that may identify you. Your answers to this survey are thus completely anonymous.

The other half will be assigned to the Public Treatment and will be shown the following screen:

"IMPORTANT: We will share your individual answers to the questionnaire on the next screen, as well as the individual-level answers of the other participants in this phase of the study, with approximately 200 UCSD students who are scheduled to participate in the next phase of the study. There is no need to provide your first and last name here; your information is already in the UCSD laboratory recruitment system.

According to the UCSD laboratory recruitment system, your first and last name are:
First Name: [first_name]
Last Name: [last_name]."

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
1000 individuals (The size of the experimental laboratory pool at UCSD has decreased due limited outreach during COVID 19, so it's not obvious I will be able to recruit 1000 subjects, but I will try)
Sample size (or number of clusters) by treatment arms
500 individuals in the Private Treatment and 500 in the Public Treatment.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
