Responding to policy signals? An experimental study on information about policy adoption and data retention policy support in Germany

Abstract

Objective We analyze whether and how individuals react to information about the adoption of a particular policy, with a focus on the role of conservatism. Methods We conducted an online survey experiment on support for data retention in Germany. A recent law on this issue allowed us to test the effects of two policy signals, information about the adoption of a new law (law signal) and information that this followed a Constitutional Court decision (law and court signal), on separate groups of respondents. Results Our results show a positive effect of each policy signal on support for data retention. The effect of the law signal was even slightly stronger for individuals with conservative beliefs. Conclusion Illustrating how lock-in effects of policies can work, our study contributes to research on attitudinal policy feedback: creating new legislation also means legitimizing the policy position in question and stating that this norm should be accepted.
