An invitation from a neighbor did not change how many people came to clean
Most people who answered the phone in three Tunis neighborhoods said they would attend, but about 3% of recruited households showed up.
The study, in plain language
In three Tunis neighborhoods, the team invited households to a community cleanup. Participants were randomly assigned to receive an invitation from a neighbor or an outsider. Everyone received the same reminders and incentives. The two groups did not differ detectably in how many said they would participate or how many actually attended.
The phone survey showed something else. Of the 947 households reached, 92% said they would attend. But among the 1,199 households recruited, 34 people came on cleanup day. The figures use different denominators, so they cannot simply be subtracted, but they illustrate the distance between saying yes and showing up. Also, living in the neighborhood did not guarantee knowing the inviter personally.
The key idea
Saying yes on the phone and showing up in the street are two different steps. Here, the gap between them was visible.
Something to think about
When someone organizes an event, how many people who confirm actually come? Someone’s absence does not prove they are uninterested: obstacles between saying yes and showing up may not be visible.
