General Information
Project description
Online experiment tested two novel public health messages on social distancing.
•Messages focused on potential to infect vulnerable people or many people.
•Participants (N = 500) randomized to see control or (one of two) treatment posters.
•Behavioral intentions and acceptability judgements of behaviors measured later.
•Both posters increased caution with respect to social distancing.

Hypothesis
We aimed to test two novel public health messages against a control message. The first was designed to exploit the "identifiable victim" effect by highlighting the risk of transmission to identifiable vulnerable persons. The second sought to counteract intuitive underestimation of exponential transmission.
How hypothesis was tested
In total, 500 Irish adults undertook a pre-registered, online experiment. They were randomly assigned to a control group or one of two treatment groups. The control group viewed a current poster that encouraged a 2-m separation between people. The two treatment groups saw posters of similar design, but with narrative messages describing how an individual had infected a specific vulnerable person or multiple other people. Later questions measured intentions to undertake three specific types of social interaction over the coming days and the stated acceptability of three other types of social interaction. Pilot work had identified these six behaviors as "marginal" - people were unsure whether they were advisable.
