Most online surveys include some form of inducement to encourage respondents to take and complete the survey, often consumer goods like MP3 players. As social science researchers, it was important to us to provide a sufficient incentive while maintaining the anonymity of respondents, not advertising a consumer product, and not providing an incentive that might bias the sample toward, for example, those who want an MP3 player.
With this in mind, we offered survey respondents an incentive in the form of a raffle for a $200 contribution to their favorite charity, to be announced on this site. Following the closure of the survey, we used a true random number generator to select three winning charities.
They are:
The American Diabetes Association, Alexandria, VA
Theatre for Living Society (Headlines Theatre), Vancouver BC, Canada
The Co-Intelligence Institute, Eugene, OR
