Uninformed
InformedBEHAVIORAL

Users will receive 20x their usual incentives for two weeks, and they will receive emails informing them about the incentives (one announcement before the incentives begin, and one email every two days reminding them about the overall incentive program). These emails will contain information about the incentives and the purpose of the incentives. The reminder emails sent every two days, however, will include more information about the overall program incentives to maximize the number of participants who learn about the incentive program at some point.
