Defaults, Framing and Privacy: Why Opting In-Opting Out

Abstract

Differences in opt-in and opt-out responses are an important element of the current public debate concerning online privacy and more generally for permission marketing. We explored the issue empirically. Using two on-line experiments we show that the default has a major role in determining revealed preferences for further contact with a Web site. We then explore the origins of these differences showing that both framing and defaults have separate and additive effects in affecting the construction of preferences.
