Abstract
The use of information provision has been criticized as an ineffective way to increase support for evidence-based environmental policies, but it remains a dominant strategy among policy communicators. Using a survey experiment on climate change and genetically modified food (GMO) policy preferences in Germany and the United States (N = 3,000 total), we investigate how information provision shapes environmental policy attitudes and whether this effect is moderated by trust in science and trust in the source of messages. Findings show that information provision significantly shifted policy preferences towards the prevailing scientific opinion, but primarily among individuals whose prior attitudes conflicted with the scientific message. While trust in GMO science moderated message effectiveness in the U.S., generally the effects did not depend on levels of trust in science or trust in the message source. Results are similar for both countries, suggesting that the findings could be relevant to different political contexts.
