4 October 2021The projection bias corresponds to the human tendency to project current preferences into the future as if present preferences will remain unchanged, omitting a range of external influences over the current preferences. We design a survey experiment to investigate the projection bias relevance on two environmentally friendly initiatives, namely solar panels and eco-friendly transport. We found that beliefs and behavioral intentions are subject to positive change when individuals are solicited a day when the weather is congruent with the proposed changes. We draw several policy and managerial implications for environmental issues.
