On 3 February 2024, we organized a hybrid online/in-person Deliberative Town Hall (DTH) in Baruten/Kaiama, Nigeria. The topic was the policing infrastructural development. To study the effects of attendance at this event, we embedded it within a field experiment, with both a pre-event and a post-event survey. The experiment includes outcomes that are grouped in several different families, and this registration primarily concerns the effects of attendance at the DTH on efficacy.
