Information sufficiency and attribution of responsibility: predicting support for climate change policy and pro-environmental behavior

摘要

This study extends the central part of the risk information seeking and processing model to examine how message elaboration influences individuals' support for climate change mitigation policy and their intention to engage in pro-environmental behavior. Data were collected through online experimental surveys at two large universities in the Northeastern United States. Results indicate that perceived issue salience triggered negative affect and information insufficiency, both of which prompted systematic processing, which subsequently led to greater policy support and stronger intention to adopt more pro-environmental behaviors. From an applied perspective, this study suggests important pathways to encourage greater message elaboration, which may lead to increased public support for mitigation policies and adoption of pro-environmental behavior.
