'Water of Gold' is a Nollywood film (a loose term referring to the Nigerian film industry), which was commissioned for the purposes of this experiment. The movie, set in the Niger Delta, is a story about two brothers. One brother, Natufe, is a poor fisherman whereas Natufe's brother, Priye, leaves the Niger Delta and returns home after getting rich by doing business only to become a corrupt politician much to the shock of Natufe, who had become outspoken about the prevalent local corruption.
In one version of 'Water of Gold', Natufe and another local activist set up a number for corruption reporting via text message and report instances of it. The other version does not contain those scenes. And the researchers discovered that 'Water of Gold' does boost corruption reporting among viewers but only when it contains the extra 17 minutes showing the movie characters reporting corruption themselves.
The movie and an accompanying mass text message campaign spurred 240 people from the 106 small communities of Nigeria to send in concrete, specific reports of corruption over a seven-month period which is a marked improvement compared to two national campaigns done to curb corruption.
Both the versions of the movie had a new system displayed to report corruption on the film's packaging and at the beginning, middle and end of the film. After the film was released, the researchers sent out mass texts where people simply had to reply to report corruption.
Littman, one of the co-authors said, I think people were surprised that the campaign actually worked.
It wasn't an accident that the study focused on the Niger Delta region, where massive amounts of oil production have not been accompanied by an equivalently substantial investment in services and infrastructure for citizens.
