Resumen de "Yes/no/not right now": : Yes/no response formats can increase response rates even in non-forced-choice settings
Eleanor Putnam-farr, Jason Riis
Although yes/no response formats have been used to increase enrollment rates in several different types of programs, their effectiveness has generally been tested in forced-choice settings. The effects on postchoice engagement have not beenmeasured. Across two field experiments in an e-mail context in which choice is not forced, the authors demonstrate a substantial advantage in click-through rates for a yes/no response format over traditional opt-in response formats. The increase in click-through rate does, under certain conditions, also persist through downstream program enrollment and participation. Finally, though noting that the yes/no format advantage is probably multidetermined, the authors discuss several potential psychological mechanisms, which are particularly relevant in non-forced-choice settings. The authors also discuss how the yes/no response format might operate in other settings, such as the implementation of mandated choice for organ donation
