dollars), both questionnaire data and results from a ï¬eld study showed that opting-in resulted in much lower levels of participation (20%) than opting-out (75%). 1. Theory: Frames and Defaults To better understand why opt-in choices differ from opt-out choices, we need to consider the mechanisms that might contribute to these differences. Table 1 shows how opt-in (Question 1) and opt-out options (Question 2) are typically presented on Web sites. Upon closer examination, it becomes clear that opting-in vs. opting-out combines two different
